I am testing simple Enterprise application but I am getting following error when I call remote method.

type Exception report

messageInternal Server Error

descriptionThe server encountered an internal error that prevented it from fulfilling this request.

SessionBean

public Object SearchData(Integer id) {
        Customer cust = em.find(Customer.class, id);
        return cust;
    }

RemoteLibrary

@Remote
public interface CustomerSessionBeansRemote {

    Object SearchData(Integer id);

}

JSP

Object o = ic.lookup(CustomerSessionBeansRemote.class.getName());
CustomerSessionBeansRemote custSession = (CustomerSessionBeansRemote) o;
Customer customer = (Customer)custSession.SearchData(1);
if(customer!=null){
     out.print(customer.getName());
}

I have added EJB and remoteLibrary project into my WAR project,so, my JSP hasa access to my Customer class.

any Help would be appriciated. Thanks.

Solution

  • "CORBA.MARSHAL" means that IDLs you use in your local and remote program are not identical and/or remote method is throwing exception which is not defined in IDL.

    This is all assuming that you're using compatible ORBs on both sides and settings on both sides are compatible.
