如何将一个jsp文件的数据用于另一个

Question

I am new in java. By using this loop i generated data in my demo2.jsp file

//it is demo2.jsp

 String sLabel
 String labelNames[]=request.getParameterValues("name");
   for(String str: labelNames)
   {
       out.println("<br>");
        sLabel=str;
      out.println(sLabel);
  }

by this i get output :-> software hardware(It is name of checkbox of demo1.jsp)

demo1.jsp

<form method="post" action="demo2.jsp">
<input type="checkbox" id="software" name="name" value="software"/>software<br>
<input type="checkbox" id="hardware" name="name" value="hardware"/>hardware<br>

I want to use that output(software, hardware) in another jsp page from demo2.jsp. for that i already created one form for POST action

//it is form of demo2.jsp

<form method="post" action="demo3.jsp">
<table>

<tr><td></td><td><input type="submit" value="Submit"></td></tr>
</form>

In demo3.jsp how should i use output of demo2.jsp is there any kind of JSP inheritance available. Please help?

Answer 1

Use JSP file include to have the same functionality at different JSPs.

<%@include file="demo2.jsp" %>

in demo3.jsp
