Hello i am a newby with EJBTransactions,
i just create some Hello World examples on how EJB works.
But after reading a lot and searching the WEB for two days i see no reason why that
should not work. Imo this should be the standard way for Client managed explicit
Transactions. Isnt it?
I already solved two non standard problems: 1st setting the jndi Props by
System.setProperty() and 2nd the non standard JNDI name of the UserTransaction is
"java:UserTransaction" instead of the spec. defined standard
"java:comp/UserTransaction".
But it always throws this Exception in the line of home.create():
javax.transaction.TransactionRequiredException: Transaction Required
at
org.jboss.ejb.plugins.TxInterceptorCMT.runWithTransactions(TxInterceptorCMT.java:316)
at org.jboss.ejb.plugins.TxInterceptorCMT.invokeHome(TxInterceptorCMT.java:74)
Imo the UserTransaction should be passed to the Bean and used.
The transaction-attribute = mandatory forced that.
// ######### The Client ##################
public class ExplicitUserTransactionClient {
public static void main(String argv[]) throws Exception {
// solves JBoss Bug: UT factory lookup failed
System.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jboss.naming.HttpNamingContextFactory");
System.setProperty(Context.PROVIDER_URL,
"http://vwplan.wob.vw.vwg:8092/invoker/JNDIFactory";);
Context context = new InitialContext();
// Lookup non standard Name of Jboss UserTransaction and start it
UserTransaction ta = (UserTransaction)context.lookup("UserTransaction");
ta.begin();
// use an EJBean, TA should be propagated to it
Object ref = context.lookup("java:/ejbtest/ejb/EXTABean");
EXTABeanHome home = (EXTABeanHome)PortableRemoteObject.narrow(ref,
EXTABeanHome.class);
EXTABean bean = (EXTABean) home.create();
// End userTransaktion (on the Client)
ta.commit();
context.close();
}
}
// ######### The Bean ##################

public class EXTABean implements SessionBean {
public EXTABean() {
super();
}

public void ejbPassivate() throws EJBException,RemoteException {}
public void ejbRemove() throws EJBException, RemoteException {}
public void setSessionContext(SessionContext arg0)

}

Thanks for your help.
