[jboss-user] [JBoss jBPM] - Re: Process files not uploaded

[gogoasa]

I my case, I used the standard SQL creation table script which comes with the jBpm distribution. I also changed the hibernate dialect to Oracle9Dialect.

The problems manifests itself as follows. Suppose you have a musicians-jndi.properties file that you included in your process archive, at the root level. In an action, trying to call an external EJB service, you would first try to load the jndi properties as follows: 

InputStream resourceAsStream = this.getClass().getClassLoader().getResourceAsStream("musicians-jndi.properties");

The exception is :
