如何在 JSP 页面中获取任何字符串值

Question

If any "ID" set with value in Servlet Class then How can i access that value on my jsp page. As i know there are several methods which helps to fetch the value by using Session management but i am tired of do it.

Please help me out.

Thanks in advance.

Answer 1

Typically the servlet calls HttpServletRequest.setAttribute to place a key value pair in the request. Then the jsp page can access this value thru the 'request' jsp variable.

Answer 2

From the servlet, set the file name in request context:

request.setAttribute("filename", fileNameStr );

In JSP write:

<%=request.getAttribute("filename")%>

Answer 3

Very simple via session, and you don't need to deal with passing parameters between pages.

File 1:

String strVal = "one";
session.setAttribute("strVal",strVal);

File 2:

String strVal = (String)session.getAttribute("strVal");
