I have a problem on SLSB. My SLSB has a database connection field, and I get
connection through container(jboss) in ejbCreate and close connection in ejbRemove. As
follows:
package com.smartcode.framework.persistence;
...
public class PersistenceBean
implements SessionBean {
SessionContext sessionContext;
Connection cn;
ClassMap classmap;
public void ejbCreate() throws CreateException {
cn = PersistenceResource.getConnection();
classmap = ClassMapGetter.getClassMapBean();
}
public void ejbRemove() {
try {
if (cn != null) {
cn.close();
}
}
catch (Exception ex) {
throw new RuntimeException(ex);
}
}
public void ejbActivate() {
}
public void ejbPassivate() {
}
public void setSessionContext(SessionContext sessionContext) {
this.sessionContext = sessionContext;
}
public ValueObject save(ValueObject v) {
try{
CommandListFactory factory = new CommandListFactory(cn, classmap);
Iterator ite = factory.createCommands(v).iterator();
while (ite.hasNext()) {
((DaoCommand)ite.next()).execute();
}
v.setAllNormal();
}
catch (Exception ex) {
throw new javax.ejb.EJBException(ex.getMessage(), ex);
}
return v;
}
...
}
When the SessionBean is invoked by a general java application through remote
interface, it works well.
But it is invoked by another SSLB A which is invoked by a general java application,
either remote interface or local interface, when SSLB A return result to client, jboss
throw a exception, as follows

I guess this problem is revelant with the connection pool, but I don't know jboss how
release a connection.
Thanks.
