<c:set var="data" scope="session" value="${param.urldata}" /> 

How do i do this using JSP tags??? Thanks in advance

Answer 1

As i understand somewhat , you are trying to send the values from JSP page to Servlet..

For this we have lot of solution

• Pass the value through method
• Set the value at session and get it wherever you want in the whole application

I prefer second point, because which hold the value for the entire application

Check Pass variables from servlet to jsp

Above question pass the value from servlet to JSP,Your question is opposite of the answer that's it..!

Set value at JSP : session.setAttribute("key","value");

Get value at Servlet: session.getAttribute("name");
