Hi Niral Soni

I modified the code as you send but the problem is it is not even calling the javascript function(reset())when i clicked on the reset button.I kept the alert message just for checking whether the function is calling or not it is not displaying the alert message.I understood that it is not calling the javascript function.What might be the problem

Hi can you tell me hot to use that length[^] in my code i have the code as follows.

var sub_dept_name = document.getElementById('txt_sub_deptname').value;

if(sub_dept_name == '')
{
alert("please enter sub department name");
document.getElementById('txt_sub_deptname').focus();
return false;
}

Thank You Bhardwaj with this query i am getting the comma seperated values when i execute the query through the query browser in mysql.But when i kept the same query in my code i am getting the exception as org.hibernate.MappingException: No Dialect mapping for JDBC type: -1. My code is like this

session = HibernateSessionFactory.getSession();

String hql = "select GROUP_CONCAT(SenderId) FROM userinfo";

senderIdValue = (String)session.createSQLQuery(hql).list().get(0);

Can you give me any idea about this exception.

Thank You Abhinav
But i am using the MYISAM engine and i am assigning the unique constraint to the column.When i have done like that the data is not importing into the table if i assign the column as unique and there are no duplicates also.

No yar My requirement is it must be string type because who ever is sending the message... that person name we can give as SenderId.

komali Guntur 13-Jul-11 3:42am View

SenderId i defined as String type to the string type Auto Increment is allowed

Thank You Mr Joan Murt
But my problem is not with the database in database it is updating the value with the given value from the application.After that whenever i am trying to enter the SenderId to the another user through the application then it has to take the all the SenderId's from the database and compare the entered value with all the existed SenderId's in the database if nothing is match then no problem it will update.But if any thing is match then it has to display the message as SenderId already exists.And i am using Mysql 5.1 DB.Am i provided the correct information or not i dont know i am new to java and forums also.If you require any more clarification i am sending my servlet class just go through it.I think you can understand.

public class AddSenderId extends HttpServlet {

public static Logger log ;
String message=null;
public AddSenderId() { }

public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Transaction tx = null;
HttpSession sesn = null;
try {
log = Logger.getLogger(this.getClass());
PrintWriter out = response.getWriter();// this can be removed.
sesn = request.getSession(false);

int userid = Integer.parseInt(request.getParameter("userid"));
String senderId = request.getParameter("senderid");
String remarks = request.getParameter("remarks");
List <userinfo> senderid_list = new UserDao().getSenderID();
System.out.println(senderid_list.size());
for(int i=0;i
