The problem is in your insert statement.

you mistyped the key word values as value.(second line in your query)

StringBuffer sql=new StringBuffer("Insert into customerTable(");
sql.append("FirstName,LastName,Role)values(");
sql.append("?,?,?)");

Thanks and regards

<set name="lineItem" inverse="true" lazy="true" cascade="all">

Hi ,
In MVC pattern we usally refer
M - Model - DataBase
V - View - JSP /HTML
C- Controller -Servlets
why can't we mention the
Servlets as View and JSP as controller.
Because both the servlet and JSP both are same.

V- View -Servlet
C - Controller - JSP
why can't mention like that?

Thanks and regards

.....<sample code>........
public class Client{
public static void main(String[] args){
new Client().doAction();
}
public void doAction() throws Exception{
InitialContext ctx=getInitialContext();
Object obj= ctx.lookup(jndiName);
home=(YOURHOME)PortableRemoteObject.narrow(obj,YOURHOME.class);
remote=home.create();
}
public InitialContext getInitialContext() throws NamingException{
Hashtable hs= new Hashtable();
hs.put("java.naming.factory.initial","com.sun.jndi.cosnaming.CNCtxFactory");
hs.put("java.naming.provider.url","iiop://127.0.0.1");
hs.put(Context.SECURITY_PRINCIPAL,"j2ee");
hs.put(Context.SECURITY_CREDENTIALS,"j2ee");
return new InitialContext(hs);
}
}
i am working in sun one application server. it is working in sun one appli server. try to execute this one, hope j2ee also support this one.
