    <p>I am sorry to change my entire concept.</p> <p>I want to forward call from <code>Servlet</code> to <code>Jsp</code>.While forwarding time I will pass parameters.</p> <p>Sevlet Program.</p> <pre><code> protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { //Creating object to FunctionNames class for calling their functions try { FunctionNames FunctionNamesObject=new FunctionNames(); //calling Method from class object List&lt;File&gt; finalListNames=FunctionNamesObject.ListOfFileNames(getServletContext().getRealPath("/copy"),".txt"); for (int fileIndex = 0; fileIndex &lt; finalListNames.size(); fileIndex++) { //Copy and pasting file from SourcePath to destination Path FunctionNamesObject.FileMoving( finalListNames.get(fileIndex), getServletContext().getRealPath("/Rod"), "TMapInput.txt" ); //.exe file process will be start from here. FunctionNamesObject.ExeternalFileProcessing(getServletContext().getRealPath("/Rod"),"ThMapInfratab1-2.exe","TMapInput.txt"); //Later Rods output files moving from one directory to another function will be added here request.setAttribute("Name","ABD"); request.setAttribute("Password", "DEF"); RequestDispatcher rd=request.getRequestDispatcher("/JSPFiles/JspTesting.jsp"); rd.forward(request, response ) ; } } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } </code></pre> <p>Jsp Code is:</p> <pre><code>&lt;% out.print(request.getAttribute("Name")); out.print(request.getAttribute("Password")); %&gt; </code></pre> <p>If you observe my code, <code>RequestDispatcher</code> code is in <code>for</code> loop,means For every iteration I want to forward call to <code>Jsp</code> file with parameters.</p> <p>in first iteration, I am getting response from <code>Jsp</code> file,but it's not working from second iteration.I am getting the following error.</p> <pre><code> HTTP Status 500 - Cannot forward after response has been committed java.lang.IllegalStateException: Cannot forward after response has been committed PackageName.ClassName.service(ClassName.java:36) javax.servlet.http.HttpServlet.service(HttpServlet.java:723) </code></pre> <p>How can I fix this.</p> <p>Thanks</p>

    2. COwe build an application using `Wolfram Mathematica` I can integrated my `Mathematica` in `JSP`, finally my `Mathematica` code is in `JSP` file. it fetch values from queryString(from URL).also we have a `.exe` file, using `Java` I can run the `.exe`. Once I run the `.exe` file it gives `.txt` files as a output.After this If I trigger my `Mathematica` Application,It imports `.exe` output files and does some heavy computations and finally some data will be saved in `DB`.

    3. CO... And why do you need to iterate over the files to do this? It really sounds like your architecture is a little broken at the moment.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
