You are trying to bind Usertransaction to the weblogic JNDI  tree. But name "UserTransaction" bound to a javax.transaction.UserTransaction object. So you need to edit your ejb-jar.xml of MyServiceBean and change the name Usertransaction to something else.

I don't have anything named 'Usertransaction'  in my ejb-jar.xml file. (see below)

Can u post the piece of code in my ejb where you use user transaction. you can go to your weblogic browser and right click on servers and do a view JNDI tree to see the list of JNDI names bound to the server. check for usertransaction and give us that info.

Can you post your weblogic.xml too? (I hope I named it correctly. This is the weblogic specific deployment descriptor that you would find co-located with ejb-jar.xml)
The names that get bound to a jndi tree of the application server is present in the app server specific deployment descriptor. The ejb-jar.xml merely contains the references.

Here is my weblogic-ejb-jar.xml -

<weblogic-ejb-jar>

  <weblogic-enterprise-bean>
    <ejb-name>
      MyServiceBean
    </ejb-name>
    <local-jndi-name>
      ejb.local.MyService
    </local-jndi-name>
  </weblogic-enterprise-bean>

</weblogic-ejb-jar>

Here is the ejb

package com.app.ejb;


import javax.ejb.SessionBean;
import javax.ejb.SessionContext;

import org.apache.log4j.Logger;

import com.util.Util;


public class MyServiceBean implements SessionBean {

  public String reflect(String string) {

    StringBuffer reflection = new StringBuffer();
    Util.showTime();

    for (int i = (string.length() - 1); i >= 0; i--) {
      reflection.append(string.charAt(i));
    }

    return reflection.toString();
  }


  public void ejbCreate() {
  }

 
  public void ejbRemove() { }

 
  public void ejbActivate() { }

 
  public void ejbPassivate() { }


  public void setSessionContext(SessionContext aContext) {
    this.context = aContext;
  }


  private SessionContext context;

 
  static final Logger LOGGER = Logger.getLogger(MyServiceBean.class);
}

I'm not referencing 'UserTransaction' anywhere in my code so this is driving me crazy!
