conn.setAutoCommit(false);


PreparedStatement pstatement = conn.prepareStatement(
"UPDATE gl_mast SET gl_descr = ?, db_amt = ?, " +
"cr_amt = ?, gl_type = ? , gl_pct = ? WHERE gl_code=?");

pstatement.setString(1, request.getParameter("gl_descr"));
pstatement.setFloat(2,Float.parseFloat(request.get Parameter("db_amt")));
pstatement.setFloat(3,Float.parseFloat(request.get Parameter("cr_amt")));
pstatement.setString(4, request.getParameter("gl_type"));
pstatement.setFloat(5,Float.parseFloat(request.get Parameter("gl_pct")));
pstatement.setInt(6,Integer.parseInt(request.getPa rameter("gl_code")));

int rowCount = pstatement.executeUpdate();
