JBPM Configuration

[dharraj]

Hello,

I am trying to understand how JBPM configuration works in the 3.1 (beta2). I am using the parseInputStream method passing it jbpm.cfg.xml which has

<string name="resource.hibernate.cfg.xml" value="/home/myhome/hibernate.cfg.xml" />

in it. However, I am getting the following exception:

org.hibernate.HibernateException: /home/myhome/hibernate.cfg.xml not found
 at org.hibernate.util.ConfigHelper.getResourceAsStream(ConfigHelper.java:147)
 at org.hibernate.cfg.Configuration.getConfigurationInputStream(Configuration.java:1265)

The file exists and it has right permissions set. Please tell me what I am doing wrong.

Thanks

Hi Raj,

org.hibernate.util.ConfigHelper.getResourceAsStream

would indicate that Hibernate is looking on the class path and I don't assume you have a file '/home/myhome/hibernate.cfg.xml' on your class path.

Thanks for the reply. So, do you know if it is possible to configure hibernate with a configuration file that is not bundled into a jar file? I glanced over the hibernate documentation but didn't see any thing that tells otherwise. Would you recommend using the hibernate Configuration object instead of a configuration file?

Thanks
Raj

The classpath can have directories as well as jars. You could add a directory, say /home/myhome, to your classpath (before your libraries, so that the directory takes precedence over any bundled file). Afterwards, specify the path to the configuration file in relation to that directory: /hibernate.cfg.xml. Note that the initial slash in this path means "classpath root" rather than "filesystem root".

Hello Alex,

Sorry I got side traced on to another problem. I can get it to work as you mentioned when I run it from command line. I have ./ in my class path and have hibernate.cfg.xml in the working directory. This works. However, I cannot get it to work if say I put the hibernate.cfg.xml in my.jar and place my.jar in /home/raj and have /home/raj/my.jar as first thing in my classpath. Actually I am trying to get it to work in Eclipse.

Thanks
Raj
