Hi guys.

I am trying to set up Eclipselink to work with my MySQL database, in particular the stored procedures. Below is my code:

User.java


LoginAction.java


Stored Procedure


When I attempt to get the result list I get the following error:


Does anyone know how I can cast the statement or if there is a problem with my code or a workaround?

Thanks for your response. That is the only line of error I have in my console.

Try using executeUpdate() method instead getResultList() method.

I thought executeUpdate() was used to run update and delete statements. It returns an integer and I need a result class.

The issue is that your procedure returns a result set, but by default @NamedStoredProcedureQuery assumes output parameters are used or no result.

You need to set returnsResultSet=true in your @NamedStoredProcedureQuery.

But please log a bug, this exception should not occur, it should always be using a CallableStatement for @NamedStoredProcedureQuery, (but you should get an empty result set without returnsResultSet=true).
