I tried to use statement.execteBatch with many SQL querys with a Advatage server..
I was always given the same message : 'SQL Attempt to produce a ResultSet from executeBatch'
Instead, everything is good if I use only one query.
Here is the code I used.

myStatement = POSIS.createStatement() ;
try{
     if(POSIS.getMetaData().supportsBatchUpdates()){
       System.out.println( "Good : Driver supports Batch Updates." );
       POSIS.setAutoCommit(false) ;
        try {
          myStatement.clearBatch();
          String sql = "Update posPrHd1 SET LINKS = 'TTTTT' where LINKS = '4M351' ";
          int iCount = myStatement.executeUpdate(sql) ;      // good
          myStatement.addBatch(sql);
          int aArray[] = myStatement.executeBatch();        // good
          myStatement.addBatch(sql);
          aArray = myStatement.executeBatch();            // not good
        } catch( BatchUpdateException bue ){
          System.err.println(bue.getMessage());
          //bue.getMessage() = SQL Attempt to produce a ResultSet from executeBatch
        }
        POSIS.setAutoCommit(true) ;
     }else {
        System.err.println( "EBRun Error: Driver " + "does not support Batch Updates." );
        POSIS.closeConnection();
     }
}catch (Exception ee) {
       System.err.println(ee.getMessage()) ;
}

POSIS.setAutoCommit(false) ;
