[Design of JBoss jBPM] - Multiple 1PC resources in enterprise

by thomas.diesler＠jboss.com

Alejandro, https://jira.jboss.org/jira/browse/JBPM-1708 If I understand you correctly, you associated the DS for the TimerEntityBean with the JbpmDS to share the same DS with the rest of the engine and not have multiple 1PC resources enlisted. | <jbosscmp-jdbc> | <defaults> | <datasource>java:/JbpmDS</datasource> | <create-table>false</create-table> | <remove-table>false</remove-table> | <pk-constraint>false</pk-constraint> | </defaults> | | <enterprise-beans> | <entity> | <ejb-name>TimerEntityBean</ejb-name> | Using the same DS for all DB related stuff seems correct to me. The EjbSchedulerTest however still fails | Running org.jbpm.scheduler.ejbtimer.EjbSchedulerTest | Tests run: 6, Failures: 0, Errors: 6, Skipped: 0, Time elapsed: 9.431 sec <<< FAILURE! | | Caused by: org.jboss.util.NestedSQLException: Transaction is not active: tx=TransactionImple < ac, BasicAction: 7f000001:bb20:48c8d180:55 status: ActionStatus.ABORT_ONLY >; - nested throwable: (javax.resource.ResourceException: Transaction is not active: tx=TransactionImple < ac, BasicAction: 7f000001:bb20:48c8d180:55 status: ActionStatus.ABORT_ONLY >) | at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:94) | at org.hibernate.connection.DatasourceConnectionProvider.getConnection(DatasourceConnectionProvider.java:69) | at org.hibernate.jdbc.ConnectionManager.openConnection(ConnectionManager.java:423) | There seems to be more to it than sharing the DS.

[Design of EJB 3.0] - Re: EJB3 Classloader Leak (EJBTHREE-1442)

by ALRubinger

Brian's correct; my switching over to the TCCL in BaseSessionProxyFactory.createProxyBusiness() leads to a CL Leak. But I'm not convinced that this is the evil piece. I *need* this code, and web injection fails without it (see http://www.jboss.com/index.html?module=bb&op=viewtopic&t=141165 for an explanation of why). However, this TCCL usage seems awfully hacky to be in EJB3 Proxy; I'd expect to always use the Container CL to generate proxies. This unfortunately will collide when a web CL needs injection and has previously defined the business interfaces with its own CL (which by Servlet Spec must look to itself *first*, and parent delegation second). Also interesting is Ron's last post, which I'll look at tomorrow.

by ron.sigal＠jboss.com

I just noticed that, in a fit of housekeeping, it looks I changed ServerThread from version 2.2 to 2.4 so that, instead of calling getClass.getClassLoader() with each invocation, it creates private static ClassLoader classLoader = SecurityUtility.getClassLoader(ServerThread.class); Should I write a 1000 times "DO NOT CREATE STATIC REFERENCES TO CLASSLOADERS"? If you make it an instance variable, does the problem go away? I'd try it but I screwed up my copy of AS 5.0.0.CR2 and I'm still downloading a clean copy from SVN.

Regarding the Remoting ServerThread I mentioned earlier: It has a reference to the TCL that defined it, but it's the CL of ejb3-connectors-jboss-beans.xml.

So: ejb3-connectors-jboss-beans.xml CL > Proxy Class > Business Interface Class > Deployment CL ? ...and that's how one CL creates a chain of linked references to the EJB_SLSB CL?

A classloader maintains a ref to all classes it has defined; the ejb3-connectors-jboss-beans.xml classloader defined that proxy class. But the business interface came from the deployment CL, since classes loaded by the deployment CL are visible to the ejb3-connectors-jboss-beans.xml classloader. The proxy's class has a ref to the business interface class.
