Problems with ResultSet from CallableStatement

Hello!

I have a tricky question.

I execute the following storedprocedure to a Oracle database:
CREATE OR REPLACE PROCEDURE getImages (p_cursor OUT SYS_REFCURSOR) AS BEGIN OPEN p_cursor FOR SELECT ID, FILNAMN FROM bild; END;

with this Java code:
callableStatement = connection.prepareCall(storedProcedure, ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
callableStatement.registerOutParameter(i+1, OracleTypes.CURSOR);

To get hold of the ResultSet I do:
callableStatement.executeQuery();
resultSet = (ResultSet) callableStatement.getObject(1);

That seems to work fine, but later on I have to do this:
resultSet.beforeFirst();

But It gives me an exception, that beforeFirst is not allowed:
java.sql.SQLException: Ogiltig Õtgõrd f÷r endast vidarebefordrad resultatuppsõtt
ning: beforeFirst
        at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)
        at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)
        at oracle.jdbc.driver.BaseResultSet.beforeFirst(BaseResultSet.java:72)
        at p6b4005.DatabaseAccessor.executeOracleStoredProcedure(DatabaseAccesso
r.java:231)
        at p6b4005.DatabaseAccessor.main(DatabaseAccessor.java:806)

Evidently the prepareCall method only effects the returned ResultSet delivered by the callableStatement.executeQuery();
And not the resulset delivered by the resultSet = (ResultSet) callableStatement.getObject(1);

But how should I do to make this ResultSet scrollable so I can call resultSet.beforeFirst();???

Best regards
