I am seeing something similar to lappi's issue. I've also perused a number of other topics re: DB driver issues, but none directly correspond to my problem, or were able to help me fix it.
I've deployed jBPM 3.0.2 to JBoss 4.0.3 SP1. I'm testing a process definition using a simple servlet in a webapp. The servlet calls some utility code, packaged within an EAR. The jBPM core libraries are packaged in another EAR. Both EARs are within the ...\server\default\deploy directory. The webapp worked fine when using the Hypersonic default DB. However, I've not had the same success with mySQL. I keep getting the following error message: 12:26:32,646 INFO [Configuration] processing association property references 12:26:32,646 INFO [Configuration] processing foreign key constraints 12:26:32,748 INFO [C3P0ConnectionProvider] C3P0 using driver: com.mysql.jdbc.Driver at URL: jdbc:mysql://localhost:1521/jbpm 12:26:32,748 INFO [C3P0ConnectionProvider] Connection properties: {user=root, password=****} 12:26:32,748 INFO [C3P0ConnectionProvider] autocommit mode: false 12:26:32,748 FATAL [C3P0ConnectionProvider] JDBC Driver class not found: com.mysql.jdbc.Driver java.lang.ClassNotFoundException: No ClassLoaders found for: com.mysql.jdbc.Driver at org.jboss.mx.loading.LoadMgr3.beginLoadTask(LoadMgr3.java:292) at org.jboss.mx.loading.RepositoryClassLoader.loadClassImpl(RepositoryClassLoader.java:475) at org.jboss.mx.loading.RepositoryClassLoader.loadClass(RepositoryClassLoader.java:377) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:164) at org.hibernate.util.ReflectHelper.classForName(ReflectHelper.java:108) at org.hibernate.connection.C3P0ConnectionProvider.configure(C3P0ConnectionProvider.java:65) at org.hibernate.connection.ConnectionProviderFactory.newConnectionProvi der(ConnectionProviderFactory.java:124) at org.hibernate.connection.ConnectionProviderFactory.newConnectionProvi der(ConnectionProviderFactory.java:56) at org.hibernate.cfg.SettingsFactory.createConnectionProvider(SettingsFactory.java:366)... etc. I deployed the mySQL driver in the ...\server\default\lib directory and added a datasource definition into the corresponding "deploy" directory. I adjusted the hibernate.properties and hibernate.cfg.xml files and checked them repeatedly. I even added a "resource-ref" to the webapp's "web.xml" file and added a "jboss-web.xml" file there, even though they weren't needed for Hypersonic. Still no luck. It seems no matter what I do, I can't get my app, or Hibernate, to recognize the mySQL driver. Any ideas to fix this would be most appreciated!
