将值从一个jsp文件传递到另一个jsp文件

Question

Suppose i'm having 2 jsp pages, page1 and page2. Now i'm including page1 in page2. I want to access some value from page1 and i want to access it within jsp scriplet tag, how can i get it without using cookie or session?

Answer 1

You cannot access variables declared in a scriptlet in page1 from page2. This is one of the disadvantages of scriptlets . Check out the answer by BalusC.

If you are using JSTL, you can do something like this in page1:

  <c:set var = "salary" scope = "session" value = "666"/>

or with request scope:

  <c:set var = "salary" scope = "request" value = "666"/>

And in page2:

<c:out value = "${salary}"/>

But really, you should be setting variables in your servlets which you can then access anywhere in the JSPs.. The use of scriptlets is highly discouraged.
