Passing parameters from one jsp file to an included jsp file?

Question

I have a servlet controller for a jsp file. I pass some parameters to this file when loading it, via request.setAttribute() , from the servlet. However, I need to include another nested jsp from the main jsp file. Will the nested file have access to the params which were sent? If not, how can I pass those params to the nested file?

Answer 1

是的，嵌套的jsp将看到从servlet控制器设置的请求范围属性。

Answer 2

use jstl's set method in the parent jsp and use the same variable in jspf.

In parent jsp.

<c:set var="foo" value="bar"/>

In included jspf.

<h2>The included parameter is ${foo}</h2>

Also you can access all the attributes set inside a servlet using request.setAttribute() in the jsp page using EL eg ${attributeName}
