A trigger causes a BatchUpdateException

Question

Hi all.
I have a big problem. I need to do a program that insert batch information to
Sybase, Firts I use PreparedStatement but when I send executeBatch() command,
throws a Exception , then I used Statement and I got the same problem.
This problem is caused by a insert trigger configured in the sybase table. Maybe
the driver can't distinguish between update counts from the trigger and insert
java sentence. I dont know.
Anybody have an idea to solve this?
I am using WebLogic 8.1 , jConnect 5.5 and Sybase 11.9.2
I send you the completa message exception and part of my example program.
Error 500--Internal Server Error
java.lang.ClassCastException

Thanks for your help.
the code for my jsp program example is :
try {               InitialContext env = new InitialContext();
ds = (DataSource) env.lookup("jdbc/Envios");
} catch(NamingException ne) {
out.println("No pudo obtener conexión a la base de datos: " + ne + "<BR>");
//crea la conexion
cnx = Sql.getCnx(ds, 5000);
Statement stmt = cnx.createStatement();
try{
stmt.addBatch("INSERT INTO cdHistoria VALUES('1234567880','MEX',getDate(),'1234567','MLOC','123',NULL,NULL,NULL)");
stmt.addBatch("INSERT INTO cdHistoria VALUES('1234567881','MEX',getDate(),'1234567','MLOC','123',NULL,NULL,NULL)");
reg = stmt.executeBatch();
}catch(SQLException bue){%>
Error causado por SQLException: <%=bue.getMessage()%>

String SQL = "INSERT INTO cdHistoria VALUES(?,'MEX',getDate(),'1234567','MLOC','123',NULL,NULL,NULL)";

Anybody have an idea to solve this?Hi. This is a followup from a post to the sybase jdbc group. Have you tried
the latest driver from them? The ClassCast exception is a purely Sybase
driver internal error.
