Have you defined any package called java.util.logging or a class inside it?

Hi,


No,i don't have any package java.util.logging


<code>
<highlight>Hello.java</highlight>
package examples;
public interface Hello extends javax.ejb.EJBObject
{

public String hello() throws

java.rmi.RemoteException;

}
<highlight>HelloHome.java</highlight>


package examples;
public interface HelloHome extends javax.ejb.EJBHome
{
Hello create() throws java.rmi.RemoteException,
javax.ejb.CreateException;
}

<highlight>HelloBean.java</highlight>

package examples;
import javax.ejb.SessionContext;

public class HelloBean implements javax.ejb.SessionBean
{

public void ejbCreate()
{
System.out.println("ejbCreate()");
}

public void ejbRemove()
{
System.out.println("ejbRemove()");
}

public void ejbActivate()
{
System.out.println("ejbActivate()");
}

public void ejbPassivate()
{
System.out.println("ejbPassivate()");
}

public void setSessionContext(SessionContext ctx)
{
System.out.println("setSessionContext()");
}


public String hello()
{
System.out.println("hello()");
return "Hello, World!";
}
}
</code>

please help me,to get through this problem.

Well, the problem is that you're adding to the classpath a .jar that defines a class in a package reserved for the JVM.

Take a look at this:

Hi,

Even after changing my classpath to bea tools.jar and rt.jar,still i am getting the same error.

I'd check the JVM version running the server and then the classpath. I'd remove from classpath the conflicting entried, as they're supposed to be included by default.
