[jboss-user] [JBossWS] - ClassCastException when trying to marshal MySql Datetime

[attila.soos]

I get this Exception when I call my WebService. I use JBoss 4.0.5.GA, MySql JDBC Driver mysql-connector-java-3.1.14, and Hibernate. In my Pojo Class I've mapped the datetime Fields as java.util.Date, and in wsdl file as dateTime. My webService works without datetime fields perfectly.

I call this function in my WebService:

Session hsession = null;
User user = null;
try {
	
	
	
	InitialContext ctx = new InitialContext();
	SessionFactory factory = (SessionFactory) ctx
			.lookup("java:/hibernate/MySqlRw");
	hsession = factory.openSession();
	Criteria crit = hsession.createCriteria(User.class);
	
	crit.add(Expression.eq("user_login_name", name));
	
	List resultList = crit.list();
	System.out.println("Size: " + resultList.size());
	if (resultList.size() > 0) {
		Iterator it = resultList.iterator();

		while (it.hasNext()) {
			
			user = (User) it.next();
			
		}
	}

} catch (Exception ex) {
	ex.printStackTrace();
} finally {

	hsession.close();
}
return user;
