jbpm getting started

[craig]

I have been able to download and build the jbpm 31 integration.

I have looked but cannot find any examples of setting up an engine which I can use withing my application. Does anyone have a 'Hello World' example which includes the applicationContext.xml ?

Thanks,
Craig

There isn't any sample for jbpm at the moment. I'll try to make one or migrate an existing one from plain jbpm to spring jbpm support. You can take a look at the tests which contain application context definitions. Can you also please, raise an issue on jira under spring modules? thanks.

[craig]

thanks for the hints Costin.

i raised the jira issue as asked.

I have looked at the tests, but cannot figure out how to set up the factorybean.

I would like to pass in a mysql connection for the hibernate. I know how to set up transaction managers, and a mysql connection...but, how would I configure it to use a specific database, with the default hbm files?

Here is what I have in my application context...it fails in the afterPropertiesSet...I am not sure which of the two configuration methods to use (JbpmConfiguration, or ObjectFactory)

any help would be much appreciated.

What's the message? Have you looked at the generated javadocs?

[craig]

Yup, I have read it all.

I also tried this:

I get this error:

getting further...i had missed the &. However, if I call getConfiguration on the hibernate session factory the return type is Configuration....the LocalJbpmConfigurationFactoryBean has a method setConfiguration, but is expecting resource.

I don't see what I should be setting, setObjectFactory, or setConfiguration.

[craig]

Ok, now I am getting there. I hadn't seen the applicationContext which was in the testing folder, i had looked in the source package.

That has all the information I need to set it up properly.

That's what I meant by tests. jbpm 3.1 support is different from jbpm 3.0 since jbpm itself has been modified quite a lot. Even though there are some similarities the classes and underlying architecture has changed - one aspect would be that you don't need to pass in a Hibernate configuration.

where is the testing folder your refering to here?

[Costin Leau]

inside the springmodules 0.3 distribution and the latest version on the spring modules cvs.
