  • 0

I’m wondering if it is possible to pass form data from index.jsp file to a java class and then back to the response.jsp. I’m trying to compute something with the data they have entered into index.jsp but it can’t be done in Javascript. Is there a way that I can retrieve the data?

The other thing is using http servelts and writing the entire html in Java, but that seems overly complex and not worth the effort if there are simpler ways of doing this.

Thanks in advance for the help!

This is one of the scripts (in javascript) that I written to try and solve this problem, but my class, RunPython.java, always comes an error?

<script type="text/javascript">

function onSubmit(){
   var Bugfile = document.forms[0]["BugFile"].value;
   var GD = document.forms[0]["GD"].value;

<%
String s = request.getParameter("Bugfile"); 
String d = request.getParameter("GD");
RunPython re = new RunPython(s,d);
%>

}

    The compiler is just trying to tell you that it cannot resolve the mentioned class in any of the imports. You need to import the mentioned class in JSP.

    <%@ page import="com.example.RunPython" %>

    This has nothing to do with passing variables around, although your attempt seems to be pretty clumsy, but this is subject to a new question.

    Unrelated to the concrete problem, you seem to misunderstand the purpose and capabilities of servlets. They are not meant to write the HTML entirely in it. Just only Java code. Start at our servlets wiki page to learn about them.
