1. Re: Best way to debug my BPEL processes in JBPM?
meghanai_99 Mar 5, 2007 4:35 PM (in response to meghanai_99)Hello All,
I tried following the settings on http://www.jboss.com/products/jbpm/downloads to get source code from cvs and I get 'connection refused' error :(D:\jbpm-bpel-trunk>cvs -d :pserver:anonymous@anoncvs.forge.jboss.com:/cvsroot/jb pm checkout / cvs [checkout aborted]: connect to anoncvs.forge.jboss.com(64.74.196.143):2401 f ailed: Connection refused
Any idea?

2. Re: Best way to debug my BPEL processes in JBPM?
aguizar Mar 5, 2007 5:30 PM (in response to meghanai_99)You can read about the ProxyWarnLog here. Searching the word "ProxyWarnLog" in this forum should also give you the details you need.
what is the best way to debug what went wrong?
Try not to rely to much on a debugger. Personally, I did; after a while I found it took too much time to find even the simplest problems. Now I prefer to examine the log file. The problem with logs is that they tend to have an overwhelming amount of useless information. Fortunately, it can be filtered :-)
JBoss AS uses log4j as its logging kit. The configuration file resides in server/[profile]/conf/log4j.xml. The log4j manual provides a great description of the configuration file format.
Hibernate can be quite verbose, in typical debug sessions I limit everything but the SQL statements:<!-- Limit the org.hibernate category to INFO as its DEBUG is verbose --> <category name="org.hibernate"> <priority value="INFO"/> </category> <!-- Limit the SQL statements --> <category name="org.hibernate.SQL"> <priority value="DEBUG"/> </category> <category name="org.hibernate.engine.StatefulPersistenceContext.ProxyWarnLog"> <priority value="ERROR"/> </category>
Note, the above also takes care of the annoying ProxyWarnLog entries popping up in the console.
jBPM emits log messages on any process execution event:15:49:28,765 DEBUG GraphElement : event 'node-leave' on 'Receive(A)' for 'Token(/primary/S)' 15:49:28,765 DEBUG GraphElement : event 'transition' on 'Transition(A-StructuredActivity.End)' for 'Token(/primary/S)' 15:49:28,765 DEBUG GraphElement : event 'node-enter' on 'Receive(B)' for 'Token(/primary/S)'
In the above extract, "A" and "B" are the activity names. By looking at nearby GraphElement entries, you can determine the activity where the fault occurred.
This information also goes to the database so that you can access it programmatically. Refer to the chapter on logging in the jBPM user guide for details.If I want to debug the source code, which port of 'localhost' I should attach the eclipse debugger with?
JBoss AS does not start the JVM in debug mode by default. If you want to do so and you are running on Windows, edit bin/run.bat. Look for "JPDA options", then uncomment the following line:rem set JAVA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=y %JAVA_OPTS%
The port will be 8787. -

meghanai_99 Mar 5, 2007 5:46 PM (in response to meghanai_99)Hello Alex,
Thank you for the prompt reply. Looking at the server log file I was thinking of changing log4j anyway. Btw what about that cvs error? It has been a while since I used cvs ...so is there anything wrong with my command? Why am I not able to get the source?
Thank you,
