Help in executing Hello World BPEL example

[gosanjeev]

I'm going through the tutorial http://docs.jboss.org/jbpm/bpel/tutorial.html#tutorial.hello.test and in the last step on running the JUnit test case named ClientTest I'm getting the following error:

run-test:
[junit] Testsuite: org.jbpm.bpel.tutorial.hello.ClientTest
[junit] Tests run: 2, Failures: 0, Errors: 2, Time elapsed: 0.411 sec

Any help would be much appreciated.

Thanks,

Please ignore my previous post. The problem got fixed when I reinstalled JDK 1.5_06.

[doankhoavy]

hi gosanjeev!
Would you like share jdk 1.5_06 ?On the Sun site just has jdk 1.5_07.I installed this jdk and also get the same problem as you.
thanks

[peterj]

Prior releases of the JDK can be downloaded from http://java.sun.com/products/archive/.

[doankhoavy]

Thanks PeterJ
Yeah, I have fixed this problem.

[gosanjeev1]

hi doankhoavy,
glad that your problem is fixed. I haven't found enough BPEL examples on JBoss environment. The only reference I have is the document titled "JBoss jBPM BPEL 1.1".
If you have come across more samples I would appreciate your sharing them.
thanks,
sanjeev

[doankhoavy]

Hi gosanjeev,
I also have the same document as you, no more
Thanks.
Do you know any designer tools for BPEL that is plugged into the Eclipse?

[gosanjeev1]

I am now investigating ActiveBPEL. They have an open source version and also a designer. http://www.activebpel.org/

[doankhoavy]

Hi gosanjeev,
Yes,the tools that i use then ActiveBPEL is easiest.
To answers your prior questtion : in addition have Oracle document
http://www.huihoo.com/oracle/docs/B14099_19/integrate.1012/b14448/hello.htm . Oracle plugin Eclipse
or IBM Process Choreographer
http://www-128.ibm.com/developerworks/webservices/library/ws-bpelwp/
These doc purpose to just understand more about BPEL.

And i have another question when the fisrt time run then server show a error message :
