JDeveloper 10g: to and BPEL

I was searching for the changes from JDeveloper to related to BPEL technology. Here the official webpages:
There are many fix lists and readme but nothing about BPEL.
Even on metalink i was not able to find anything...
So if anybody knows how to get the lists with the JDeveloper patches related to BPEL, please add a comment to this blog ;-)

Oracle SOA Suite 11g: How to get a running test instance (on a laptop)?

After migrating the first project, the next step is to deploy this bpel to a server. I started with only installing JDeveloper an let's see, if it possible to stay with that (without installing the real wls production server).

I started with just with

So this looks like the wls server can be configured with Getting started with WebLogic Server 10.3.1:

But after some clicks i ended with:

Ok, there was only a very small chance, that a database is included inside the jdev-package. Like expected i installed Oracle's XE database. And after a short search i found a nice guide for setting up test instances inside

Just to add the missing steps:
dpkg -i oracle-xe-universal_10.2.0.1-1.0_i386.deb
/etc/init.d/oracle-xe configure
oracle@hades:~/app/oracle/product/10.2.0/server/bin$ ./
lsnrctl start
sqlplus system/passwd@XE
and as written in the Oracle documentation - download the rcu and run it:

Ok, ignore this, but then:
RCU-6107:Fehler bei der Prüfung auf Voraussetzungen von DB Init Param für: SHARED_POOL_SIZE
Erforderlicher Wert = 147456 KB, Aktueller Wert = 0 KB, Vergleichsoperator: ">="
RCU-6107:Fehler bei der Prüfung auf Voraussetzungen von DB Init Param für: SGA_MAX_SIZE
Erforderlicher Wert = 147456 KB, Aktueller Wert = 143360 KB, Vergleichsoperator: ">="
But this is fixable:

SQL> alter system set sga_max_size=150M scope=spfile;
System altered.
SQL> alter system set sga_target=150M scope=spfile;
System altered.
and restart the DB:

Once again:

Then i tried via Jdeveloper -> Run -> Start Server Instance
But the result was just many errors and no connectivity via http://localhost:7001.

Then i tried
cd /opt/Oracle/Middleware/user_projects/domains/DefaultDomain/
And after waiting 2 minutes, it worked:

Review at amazon: SOA Principles of Service Design

Last week i read the first book from Thomas Erl.

It is a very nice book, if you have to build some slides or if you want to give a lecture. But really deep insights into the topic service design is not provided. For example chapter 6 "service contracts" covers only a simple WSDL as example.
Nearly 50% of the book is occupied by fancy graphics, but most of the are quite useless or without any additional value.
Perhaps it was just the wrong book from Thomas Erl, so i will try another one, too...
If you like, take a look at my review at (It is written in german, sorry again ;-).

Migrating BPEL projects from 10g to 11g (example: 101.HelloWorld)

On this blog i started more than one year ago with the lost (collaxa) BPEL-tutorials. My first posting was the 101.HelloWorld.
Now after the arrival of Oracle's application server 11g i decided to do all the tutorials again to see what has changed. So let's start:
First you need to download jdeveloper 11g and add the bpel components.
Then get the old bpel tutorials (you can copy them from an 10g installation area: /opt/oracle/product/
After that open jdeveloper and create an application:

Then you have to create a project, even we do not need this here:

Then you can click finish.
Now choose open and select the HelloWorld.jpr:

This starts the migration wizard:

And the wait:

Done! So let's see what happened.
Ok, much more files than in 10g:

The bpel itself has one transformation more than before:

Opening the transformation, i got the following error:

But after restarting jdeveloper, i was able to access this xslt.

In addition a composite was generated:

The test suite was migrated, too

As a difference to 10g the tests are added at composite level and not inside the bpel (the blue arrow inside the light blue circle).

Double clicking this arrow opens this dialog:

And Generate Sample does really work (it changes Kireet to name1 ;-)....
Deploying and checking will be done in another posting.
