Starters-Kit 3.1.2 Problems

[rbowman]

Hey guys,

I'm trying to work through the "Getting Started" guide, but I'm having a few problems. I am trying to run this on OpenSuse 10.1, so I started the jboss server by running the following:

./run.sh -c jbpm

I have made sure that proper permissions were set before doing this. As the output goes flying by, I have noticed that it gets to a certain point and the log output keeps printing the same thing every five seconds:

10:40:57,405 DEBUG [JbpmContextInfo] creating jbpm context with service factories '[message, scheduler, logging, persistence, authentication]'

I am not sure what this means. Can anyone help me out?

Also, when I imported the jbpm project into eclipse (${starters-kit-home}/jbpm), I have noticed that org.jbpm.msg.command.AsyncExecutionDbTest.java has errors. Specifically, eclipse is complaining about the methods CommandExecutorThread.getStackTrace() and CommandExecutorThread.getState() not existing. Because of this, I cannot seem to build the mysql scripts by executing:

cd ${starters-kit-home}/jbpm-db
ant mysql.scripts

I get the following output from ant:

$ ant mysql.scripts
Buildfile: build.xml

I just downloaded the starters-kit yesterday. Any help would be greatly appreciated. I am trying to figure out jbpm for use on a complex software request automation project.

Thanks,

The first part looks normal to me - I've been interpreting it to mean that jBPM is up and running and periodically polling existing processes to see whether anything needs to be done.

[rbowman]

Thank you for your quick response.

I suppose it's fairly obvious that I never checked with a web browser to see if it actually worked. I thought since I never saw anything come across the log like "server started in..." that jboss never actually started.

Anyone have any ideas about the DB scripts?

That's a bug. There is a compile error in a few of the JUnit tests. You can either change the source in jbpm yourself to remove those errant lines (just used for debug), or not build those tests by editing the ant build.xml

Hi,
I got this kind of error message recently. After "set JAVA_HOME=e:\app\JAVA5" and ant again, everything is ok!

Try to compile under JDK 1.5 rather than 1.4.
