Question

I have written a sample EJB class as shown below :

@Stateless(mappedName = "BusinessSLSB")
@Local(BusinessLocal.class)
@TransactionAttribute(value = TransactionAttributeType.REQUIRES_NEW)
public  class BusinessSLSB implements BusinessLocal{

            //body of the class

}

I have a non-EJB class in the same project and I try to lookup the file in the following way :

public class GetTransactionData {
private BusinessLocal business;
public GetTransactionDataForMercury(){
    notifier.info("Creating an object of GetTransactionData");
    try{
        InitialContext ctx = new InitialContext();
        business = (BusinessLocal) ctx.lookup("BusinessSLSB");
    }catch(Exception ne){
        notifier.error("Error occurred --> " + ne.getMessage());
    }
}

When I am executing the code, I am getting the following exception :

Error occurred --> Unable to resolve BusinessSLSB. Resolved '

Am I going wrong in providing the lookup name? How can I resolve this issue?

Answer 1

I have found the solution for such a problem. The solution is add the following lines in the web.xml file :

<ejb-local-ref> 
    <ejb-ref-name>ejb/BusinessLocal</ejb-ref-name> 
    <local>dk.tdc.soa.smo.draco.ejb.BusinessLocal</local> 
 </ejb-local-ref>

and the following lines in GetTransactionData :

public class GetTransactionData {
      private BusinessLocal business;
      public GetTransactionDataForMercury(){
      notifier.info("Creating an object of GetTransactionData");
      try{
         InitialContext ctx = new InitialContext();
         business = (BusinessLocal) ctx.lookup("java:comp/env/ejb/BusinessLocal");
         }catch(Exception ne){
      notifier.error("Error occurred --> " + ne.getMessage());
      }
}
