Java.lang.OutOfMemoryError without ResultSet

Question

Hi everyone,
I am getting a java.lang.OutOfMemoryError when I call a Stored Procedure in Microsof SQL Server...
This procedure reads lot of tables to process the data and insert in another table...The process is HUGE in the SQL Server....The SQL Server runs in another computer...
Here are part of my java code:
     Connection conn = ResourceManager.getConnection();
     CallableStatement cs = conn.prepareCall("{call sp_FillLinks(?,?,?,?)}");
     cs.setString(1, banda);
     cs.setInt(2, spNtcId);
     cs.registerOutParameter(3, Types.INTEGER);
     cs.registerOutParameter(4, Types.INTEGER);
     cs.executeUpdate();
You can see that there's not exists ResultSet occuping the virtual memory...
But when i look at the Task Manager, the memory used by the java.exe process oscillates until to blow up the heap size that i have configured with -mx512m ...
I tested it with two JDBC drivers (Microsof and UNA2000)....and the problem persists...
Well, The question is ...Why the java are ocupping memory if the work is
being made by the SQL Server ??...I searched the forums but dind't find the answer I need
Thanks
Juan

Hi jschell...Thanks for replay..!!!
Do you know how can I make that Stored procedure doesnt return ResultSets..??
Or..What instruction in SQL return ResultSet...?
Where can I find more about the relation betwen SQL and Java ResultSets..?
For example in this StoreProcedure...I use :
INSERTS ..
UPDATES ..
CURSORS .. (CREATE, OPEN, FETCH, CLOSE, DEALLOCATE )
SELECT ..
BUT ONLY IN THIS FORM:
     SELECT @DetLinkNSeqDet = NSeqDet,
@DetLinkPesoStnDw = PesoStnDw
     FROM SpDetLinks
     WHERE      Banda = @Banda AND
          SpNtcId = @SpNtcId AND
          NSeqCab = @CabLinkNSeqCab AND
          StnNameDw = @StnNameDw
