Hi all , i am using RedHat6.1 , postgres7.01.,jdk1.3 , and jboss2.1.
I have finder method below :
It did not display records when call the finder method eventhough
that were some records in the database.
The errors is not always occured , this is the method in the session
bean which call the finder method :
public ArrayList searchByLikeCompanyname(String companyname) throws
RemoteException,FinderException{
ArrayList result = new ArrayList();
Collection collection =
usercompanyHome.findByLikeCompanyname(companyname);
Iterator iterator = collection.iterator();
while(iterator.hasNext()){
UserCompany usercompany =
(UserCompany)javax.rmi.PortableRemoteObject.narrow(iterator.next(),
UserCompany.class);
UserCompanyJB usercompanyJB = usercompany.getCompanyJB();
result.add(usercompanyJB);
}
return result;
}
Anybody have any idea ? I have include also my ejb.jar
