Hi,
I am new to maven 2 and am trying to migrate my maven 1 projects to maven 2.
I am trying to use xdoclet maven plugin to generate ejb interfaces and
deployment descriptor files.
The ejb container used is weblogic. The xdoclet maven plugin seemed to have
executed correctly (that's what I think), but when I try to use the
weblogic-maven-plugin after that to create the stub classes and the jar, I
get errors.
I only have a simple stateless session ejb. I get a
weblogic.utils.compiler.ToolFailureException exception with EJB specific
messages which also include entity bean specific messages.
I do not know where am I going wrong ? Is my approach right?
Here's the code
/* TimeXMEJB.java */
package com.harland.maven2ejb.server.session;
import javax.ejb.SessionBean;
import javax.ejb.EJBException;
import javax.ejb.SessionContext;
import java.rmi.RemoteException;
import java.util.Date;
/**
* This is the EJB TimeBean
*
* @ejb:bean type="Stateless"
* name="MyTimeXM"
* display-name="EJB MyTimeXMBean"
* view-type="remote"
*
* ... other javadoc tags ...
*/
public class MyTimeXMEJB implements javax.ejb.SessionBean {
/**
* Get time
*
* @ejb.interface-method view-type="remote"
*/
public String getMyTimeXM() {
return "Time is : " + new Date().toString();
}
/**
* @ejb.create-method
*/
public void ejbCreate() { }
public void ejbPassivate() {}
public void ejbActivate() {}
public void setSessionContext(SessionContext context) {}
public void ejbRemove() {
}
}
