A while ago i posted something about continuous integration for osb on a linux machine running bamboo. At the end of the build cycle (code checkin by dev, tool detects change, checkout, build, deploy) you like to run tests to see if the code that was just checked in…did not break anything.
In the case of service bus technology you preferably like to do end-to-end testing….meaning something like….
putting input somewhere….
service does its VETRO ( validate, enrich, transform,route and operate) thingie
and the ouput gets validated …
For synchronous services the strategy for testing could be…
- create a test facade that calls the service you like to test
- the service stores the output of the message using the wli osb reporting tables, storing $body witha key that has a unique id…for e.g. The internal $messageID variable…
- the service returns the messageID in the header with an inbound response to the testfacade
- thetestfacade does a query in the wli report data table using the id that was given in the header
I made a poc for that…and that works fine… If everything is synchronous …even over more services , this should enpose no problem…as long as the services pass the correct information via the header.. In my poc i had to do 2 tricz to get this running…
- include a timer that delays the query to the reporting table…the services repond quicker than the persistance of the body in the database…therefor i implemented a Thread.sleep in a java callout
- You need to sql the following in order to get the xml content from the blob table… select utl_raw.cast_to_varchar2(dbms_lob.substr(BLOB_FIELD)) from TABLE_WITH_BLOB where ID = '';
…you can get the code from my repo….
For asynchronous services this is a complete different story… Often there is some queueing mechanism in place…and the main question will be then…
Which input file is responsible for which output file….with async services i cannot find a way to link the input with the output….perhaps content based?… Or do something smart with the facade ( test directory Or something like that) in any way …for now i will just assume that i am the only one testing or using a certain service at the time….then my strategy for now will be…
- let junit put file in the input of service
- wait some time
- let junit pick up the result from the configured endpoint of the service….do some testing…and voila
Seeing Oracle XML database technology in action using the Oracle Service Bus.
Prerequisites
An Oracle Database that can handle tables of XMLTYPE, (Oracle DB XML): Tip download the excellent Virtual Box images from the http://www.oracle.com site
An Oracle Service Bus installation
Steps
Log in to the database (with sqlplus or sqldeveloper) and create a table of XML type;, for e.g.:
create table chris_test of xmltype;
In sql developer you will see something like this:
NOTE that you did not have to create columns and their types…you just created a table of XMLtype
You can xquery this table…which I will show you later on…
For our example you need to create a datasource on your weblogic console (your OSB machine) named jdbcDS that can access the Oracle XML DB we just used
In your OEPE create a new XQuery resource, by select new –> XQuery Transformation (what is in a name)….
Put the following content in your xquery resource….
Note (the double ‘ signs)…escaping quotes
xquery version "1.0" encoding "UTF-8";
(:: pragma type="xs:anyType" ::)
declare namespace xf = "http://tempuri.org/OSBProject1/xquery/lookup/";
declare function xf:lookup()
as element(*) {
fn-bea:execute-sql(
'jdbcDs',
'rec',
'select XMLSERIALIZE(CONTENT COLUMN_VALUE AS CLOB INDENT SIZE=2)
from XMLTABLE
(
''for $i in fn:collection("oradb:/OE/CHRIS_TEST")/PO[CUSTNAME/text()=$REFERENCE]
return $i/CUSTNAME''
passing ''Chris'' as "REFERENCE"
)')
};
The fn-bea:execute-sql function takes 3 params in this case (other variations are possible…RTFM
1st param is the name of the datasource
2nd param is just a variablename for each record
3rd param is the actual xquery / sql query …
Now just create a Proxy Service with an ASSIGN….that refers to this xquery….Happy testing…
your proxy service…which will only output the results of the database xquery lookup
The Assign function…In which you refer to the XQuery resource…In my example it is called lookup.xq, I assigned this to variable XXX
In the logging in do log the $XXX variabele….
you will see something like this in your logging then…
Earlier I made some movies on this topic (lazy documentation)…now I have them on youtube…
Having experience with continuous integration tools like cruise control and hudson for java projects, I now wanted to implement this strategy for development and testing for an OSB/ ALSB project using Bamboo as CI tool.
My o my what a nightmare, nothing to be found on the internet about this topic…..
I finally got everything working eventually (3 days) …
GOAL
Have an environment that is deployed an test automatically after each change in the repository. One of the most important reasons for companies to implement Service Bus technology is transformation of messages. Therefore I like to achieve that after each change to the code, the Services are being tested on expected input and expected output. Ideally every OSB project will have a testproject that encapsulates the expectations and testcases for each project.
LINUX MACHINE RUNNING: Subversion/ Bamboo/ and OSB
Development Machine: Running whatever with Subversion plugin to checkin code
This picture below explains Continuous integration building and testing in a nutshell….
Note: Actions 1 – 4 are performed on the build server, After a fix the sources gets checked in again…and the cycle starts again….HENCE continuos
PROBLEMS
I had several problems, but synchronisation was the main problem…
There are many blogs on the internet show you how to do an export and deployment of OSB projects…however if you have an OSBProject1 that is linked to an OSBConfiguration1 and you update the project (like an svn update, which is what BAMBOO does in case of a build)) then you have a problem…..
If you dont believe me try do the following:
In OEPE create a OSBConfiguration
In OEPE create a OSBProject, put some test proxyService or business Services in them
In OEPE link the OSBProject to the OSBConfiguration
NOW exit eclipse and go to your workspace
make a tar of your current OSBProject (we will simulate SVN behaviour, by putting a backup back)
Open Eclipse and change something in your current current OSBProject, then Close eclipse again
Now untar your OSB backup …hereby overwriting the change in your current project
Now try do the export from OSB again…… (Remember you have your eclipse closed) you will notice that even tough you only have overwritten 1 proxy file that the build will fail because the file that you have overwritten is not synchroized with the OSBConfiguration anymore. For this you need to start eclipse again. I have spent a lot of time searching for the correlation and the only correlation I could find for now is between the Project and the Configarion in several files, no on artifact level tough. And no matter what I tried with manipulating (with shell sed scripts) nothing worked…appearantly there is some OSB/Eclipse magic going on….so in order to make this project run (Continuous Integration with OSB) I need to have OEPE/ eclipse open for the synchronization.
Lesson Learned: In case of Continous Integration whereby SVN is updating your OSBProject, have Eclipse/ OEPE run in the background to take care of the Synchronization otherwise the export of OSB which is done by com.bea.alsb.core.ConfigExport will fail with a 101 ERROR
After writing this POST I had another problem with projects with JCA components… When doing the export of the OSB projects I got the following error:

Exporting to /tmp/sbconfig.jar… 21-Dec-2011 09:29:03
Error during configuration jar export.
Until now everything was working with with Standard OSB artifiacts, however when Projects refer to JCA components you go the error like above.
After some googling aroung I found out that it was related to the 64 bit version of OEPE that I was using for creating the Export. I used the same scripts on the same projects on my local Linux machine which runs a 32 bit version of OEPE and then it works fine….how about that.
STEPS
On your build server (see pic) make sure you have OSB with OEPE installed
Run Eclipse OEPE on your linux machine; You need to run Eclipse on the Linux machine, I will explain how to do this (generate key, X11 forwarding etc etc) (some tips, run eclipse by nohup ./eclipse & and make sure your session is not killed by updates and a rebooting machine…happened to me too a couple of times)
On your build server (see pic) make sure you have BAMBOO install and configured
You will probably have the following situation, you work on windows machines, you access your linux machine using putty or some kind of other terminal and you have a personal username and password to access the machine.
Once you accessed the machine, you will need to sudo in order to become the user for starting and stopping your oracle/ bea software.
Note It is not possible to open an X11 session with X11 forwarding while your logged in as user A and you start the X11 session as user B… the X11 forwarding needs the .Xauthority file which resides in your home directory of your user.
The following steps will explain you how to start an X11 session on your windows box….the X11 session is needed for the Eclipse GUI on linux.
- Logon to the linux box using your own account, then sudo to the user you suppose to be… for example sudo su – osb
- Create a ssh key with the following command (I prefer type DSA…not mandatory) ssh-keygen -t dsa
just fill in the default values…do not fill in a password…this is much easier
At the end you will have a .ssh directory in your home directory with the following files:
now copy the id_dsa.pub into a file named authorized_keys, this file is not created by default
now copy the private key (id_dsa) to your windows machine using winscp or some other SFTP client.
On your windows box convert your private key into the PKK format by running….puttygen.exe
press on Load Private Key and load the private key you just uploaded
After succesful loading you will see something like the screen below:
Then Press the “Save Private Key” button in order to save the key in ppk format…save it as <filename>.ppk (Note in the example above I used a password…this is not mandatory) PPK is Putty’s own format…
This key you can use for logging with your user…If it is not working …talk to your NIX administrator…it could be that some permissions needs to be set on /etc/ssh/sshd_config
In your putty session configure your putty session to use the PPK key you just created…see screen below:
Also turn on your X11 forwarding…see screen below…
The MIT Magic Cookie will be saved in your.XAuthority file in your home directory…when you log in….Instructions for setting up X11 on your Linux box…for e.g. http://www.wikihow.com/Configure-X11-in-Linux
Now start eclipse by running nohup ./eclipse & (this will make the oepe run even after closing down the session (unless you kill eclipse itself)…also make sure that your linus administrator did not configure a session timeout for your sshd sessions
create an OSB configuration…In your OEPE project explorer, right click the project browser and select OSB create Osb Configuration, Name it something without spaces, for e.g. OSBConfiguration1
via console checkout all the projects you want to have build…
This is something you do only initially: Open a console and check out your projects in the workspace of eclipse
for e.g. cd /home/oracle/workspace
svn co http://someServer.com/svn/OSBProject1
- then in eclipse import your project into eclipse…Right click resources explorer, IMPORT , IMPORT, Existing projects into workspace
Select the project you just checked out, you get something like this below then…
link your projects by dragging the project into the OSBConfiguration, it will look something like this then…
4 Configure Bamboo …
Put the build scripts in a directory on your server….
for e.g. in /home/oracle/scripts/osbbuild we will need the following scripts:
import.py; a python script for actually deploying the osb artifacts into a preconfigured OSB environment
build.xml; the ant script responsible for building and copying stuff
build.properties; the file needed for configuring the scripts

Now we configure Bamboo…Login to the bamboo console
Create a Plan…which will encorporate the behaviour of 1 or more projects….than add a project and configure its tasks
the 1st task is SVN Checkout…see the1st picture (make sure you checkout from the proper trunk/ branch or whatever)
2nd and 3rd taks are ANT tasks, 1st ANT task is for building/ exporting the osb artifacts (with the changes from the previous subversion checkout), 2nd ANT task will call the actual import task for importing the deployable onto the preconfigured deployment server….You could also combine this into 1 task, but I chose to seperate it into 2 tasks for debugging purposes
The Maven task is needed for executing the Junit test cases (will be handled another time)…
The last step for parsing the sure-fire test results is not really needed…and will not be discussed any further
in the 1st ANT task I configure the following in Bamboo
- Task description; just a name for the task
- Excecutable; a link to the preconfigured ant installation which must reside on the same machine
- build file: this is the location to the build.xml file (command line it would be something like ant -f <build.xml>)
- In Target I fill in the following
- 1 st param is the name of the task: buildOsb (see source)
- 2nd param -DProjectName=CommonOSB; in the build.xml you see a reference to this param ${ProjectName} this is name of the project we just checked out from SVN, this reference is also used in the eclipse workspace
- 3rd param -DBambooName=<someBambooName>; in the build.xml you see a reference to this param ${BambooName} this is the Bamboo directory we are using, this is needed because we will copy files from this directory into our eclipse workspace
- in CLASSPATH, I just used the $CLASSPATH which I get if I do a setWLSEnv.sh
Best of luck to you…may the force be with you
If you need help, just give me a mail: chris@datalinks.nl
Implement a simple ProxyService that reads a file with a Java CallOut,
do something with the File and present it’s output in HTML
I know ProxyServices are note meant for Presentational stuff and all that other blabla…,
but I like to use technology the way I like it and not because people say it needs to be used in a certain way.
In Eclipse:
create OSBConfiguration
create OSBProject
create Java Project
In the java project create a class that does your file Reading and creates HTML output.
something like this…. NOTE that your output method needs to be STATIC
import java.io.File;
public class VersionReader {
public VersionReader(){
}
public static String constructInfo(){
StringBuffer sb = new StringBuffer();
sb.append("<HTML>");
sb.append("<H1> HELLO WORLD !!!!!! </H1>");
sb.append("</HTML>");
}
}
! OSB can directly handle (do something with it) SimpleTypes and XMLTypes, ComplexTypes like Lists of of Objects or HashMaps can only be passed through as reference.
In eclipse create an export of your java sources in the form of a JAR file:
Right Click on your Java Project do a export, select OTHER and then choose JAR
In your OSB Project Create a Jar Folder and Drag the JAR file you just created into your OSBProjects’ JAR folder….
Now in your OSB Project Create your Proxy Service
Click something together That looks something like this
PipeLine PairNode, 2 stages, stage 1 java call Out, stage 2 replace and transport header
Defined 2 stages for debugging purposes…not really needed
Confgure your Java callout like this…
In the Java callout you will get a dialogue that forces you to point to a java class (point to the JAR file you dragged earlier)
then select the static Method you programmed earlier.
As you will see, OSB is smart enough to see that the result Type is of the Simple Type String. The output I assing to an OSB variable named htmlOutput
In the replace Message Processing step I configure the following:
Simply put I place the content of the Java Callout into the body result of this ProxyService, Note that I checked the Replace Node Contents radio button
So far this has been standard OSB stuff, but now the trick for Presenting XML output (that contains a HTML string) in your browser….
You need to Configure the COMMUNICATION step Transport header in order to Trick your browser in order to accept this…
Direction is INBOUND RESPONSE
Select CONTENT-TYPE and configure the expresson to “text/html”
Deploy this stuff and call the Proxy Service in your browser and behold your result:

# it will also maintain a version file in the home directory of the soa user
# Note: Dirty hack in order to make sed accept params…
# Note that $1 must be the version Name then!!!

Versioning of OSB artificats is a bit more complex…than regular web applications..
Some people use the version numbers in the artifacts which is a lot of hassle.
Why do we do versioning: we like to see which version is deployed in production (or any other environment)
my strategy
Tagging version
svn checkout
create versionFile (this will be used if you deploy for the version webapp)
add version number to all artifacts
svn mkdir tags/<version nr>
svn checkin
svn copy trunk/project tags/<version nr>
Making Description empty again
svn checkout from trunk
remove versionFile
remove version from artifacts
checkin
Deployment based on tag
checkout tag from svn
make sbconfig.jar
generate list of artifacts
publish generated artifact list with version number to versionProxy
Checkin version
Via the web app…will read textfile or via versionProxyService
Decided to make a app for it…..TO BE continued!!!!
Things I tried adding version number to description
Deployment plan, does not work for OSB deployments
Customization file, only search and replace of things it can find…not descriptions
wlst, not possible to change description of items…you can enable disable and rename but no property for description anywhere
java, not possible to change description of items…you can enable disable and rename but no property for description anywhere, the ProxyService? BusinessService and ALSBConfigurationMBean do not support change of description
I remember I had this issue a while age….but to my shock I did not blog it…Because my great inspirator Mr Vernetto Blogs everything with javamonamour…I will be a better boy now and start documenting…
Anyway
Because weblogic uses some libraries of the OS for encryption and decryption it is adviced to use the /dev/urandom library in stead of the defaul /dev/random lib…this can have a major impact on performance.
there are several ways to enforce this…but my favorits is to do it on OS level by making a symbolic link.
as root:
cd /dev
rm -f random
ln -s /dev/urandom random
svn: Could not use external editor to fetch log message; consider setting the $SVN_EDITOR environment variable or using the –message (-m) or –file (-F) options
svn: None of the environment variables SVN_EDITOR, VISUAL or EDITOR is set, and no ‘editor-cmd’ run-time configuration option was found
you can set vi as your default SVN editor like this:
To work under version control the best thing to do is the following:
- mv the current project directory to a tmp directory (backup precaution)
- Checkout the project from the repository… and work with this copy, you can checkout via:
svn co file:///home/oracle/repository/myFirstSvnProject
NOTE
it is best practice using the promotional model (google it
go to your project directory
svn mkdir trunk
svn mkdir tags
svn mkdir branches
(trunk will be the main (latest) version where developers work on, tags are meant for tagging certain releases (usually this is a copy of certain files in the trunk at a certain moment), branches are meant for developers who need to go their own way )
start the deamon
svnserve -d
(for always starting after reboot do: chkconfig svnserve on)
