Query is not defined Exception while Executing Finders

Question

Hi,
We have used Toplink 2.5.1 & weblogic 5.1 for a year. All works great. Recently we are upgrading to Weblogic 7.01 and toplink 903. Inorder to make previous finder methods work, I created a Class DescriptorManager add a lot static methods each for one entitybean. In Mapping Workbench, I did:
.Select Advanced Properties > After Load from the menu for the bean.
.Enable the amendment method for the descriptor by specifying the class and name of the static method.
The code which in the DescriptorManager.java is:
public static void addDescriptorFinders(Descriptor descriptor)
     * Enumeration findDescriptorByServiceType(BigInteger stypeId)
ReadAllQuery query1 = new ReadAllQuery();
query1.setName("findDescriptorsBySrvcTypeId");
query1.addArgument("lStypeId");
query1.setReferenceClass(MeDescriptorBean.class);
ExpressionBuilder builder = new ExpressionBuilder();
query1.setSelectionCriteria(builder.get("serviceType").equal(builder.getParameter("lStypeId")));
descriptor.getQueryManager().addQuery("findDescriptorsBySrvcTypeId", query1);
In Here is MeDescriptorHome:
public interface MeDescriptorHome extends EJBHome {
     public MeDescriptor findByPrimaryKey(MeDescriptorPK key) throws FinderException,RemoteException;
public MeDescriptor findByGroupId( BigInteger groupId) throws FinderException, RemoteException;
     public MeDescriptor findOneByQuery(ReadObjectQuery query, Vector args) throws FinderException,RemoteException;
     public Collection findDescriptorsBySrvcTypeId(BigInteger serviceType) throws FinderException,RemoteException;
I write a test client, which call
findByPrimaryKey
findOneByQuery
findByGroupId
findDescriptorsBySrvcTypeId
The first two works.( which are toplink reserved query), the other two do not work. Can someone help me please? Thanks a lot!
Here is the error message I got:
Error during finders:

Answer 1

You are on the right track for sure. You should make sure that the <ejb-ql> node in you ejb-jar.xml file is empty, and that the arguments for the finder are specified correctly.
Next, I would make sure that the descriptor is, in fact, being amended. Maybe just throw a debug line into the descriptor amendment method for your MeDescriptorBean and make sure it is being called after you re-start the server.
