[JBoss jBPM] - Re: Changes to Task object not reflected in DB
by zhanglikui888＠sina.com
I have the same problem,the below code is the detail:
JbpmConfiguration config=JbpmConfiguration.getInstance();
JbpmContext jbpmContext=config.createJbpmContext();
//Session session=jbpmContext.getSessionFactory().openSession();
//Transaction trans=session.beginTransaction();
ProcessDefinition pd=jbpmContext.getGraphSession().findLatestProcessDefinition("baoxiao");
//ProcessInstance pi=pd.createProcessInstance();
ProcessInstance pi= new ProcessInstance(pd);
pi.getContextInstance().setVariable(Constants.ISSUE_USER, Constants.userName);
TaskInstance ti=pi.getTaskMgmtInstance().createStartTaskInstance();
ti.setVariable("baoxiaoId", 6);//baoxiao.getBaoxiaoId());
ti.end();
the log is follow:
2008-06-01 17:26:43,906 [org.hibernate.engine.StatefulPersistenceContext.ProxyWarnLog]
[WARN] Narrowing proxy to class org.jbpm.graph.node.StartState - this operation breaks ==

[JBoss Cache: Core Edition] - Bad registration of class loader
by yair.zaslavsky
Hi all, I have a class that wrapps "get" and "put" of TreeCacheMBean (The class gets an object of TreeCacheMBean using the code:
MBeanServer server=MBeanServerLocator.locateJBoss();
| TreeCacheMBean cache=(TreeCacheMBean)MBeanProxyExt.create(TreeCacheMBean.class, "jboss.cache:service=TreeCache", server);
|
)
When i invoke the get and put methods I get the exception:
java.lang.RuntimeException: java.lang.ClassNotFoundException: No ClassLoaders found for: com.cellerium.logicsrv.logic.resource.data.BinaryResource

I did use "registerClassLoader" (in my wrapping class i have an init method that performs:
treeCache.registerClassLoader("/", this.getClass().getClassLoader());
Can anyone tell me why i am getting this exception?
