Random behaviour of Redirect JSP (URGENT)

I tried to create Oracle PDK java portlet that will have multiple JSP. Which i want to call one after the another in the flow.
I did created in entry in provider.xml sas follows
<pageParameterName>rs_next_page</pageParameterName>
My JSP has sample code as follows
<%@page contentType="text/html; charset=windows-1252"
import="oracle.portal.provider.v2.render.PortletRenderRequest"
import="oracle.portal.provider.v2.http.HttpCommonConstants"
import="oracle.portal.provider.v2.url.UrlUtils"
%>
<%
PortletRenderRequest pReq = (PortletRenderRequest)
request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
%>
<P>Hello <%= pReq.getUser().getName() %>.</P>
<P>This is the <b><i>Show</i></b> render mode!</P>
<form name="actItem" method="get" ACTION="<%= UrlUtils.htmlFormActionLink(pReq,UrlUtils.PAGE_LINK) %>">
<%= UrlUtils.htmlFormHiddenFields(pReq,UrlUtils.PAGE_LINK, "actItem") %>
<input type = hidden name = "rs_next_page" value = "/htdocs/editresources/editresourcesEditPage.jsp">
<input type="submit" value="Submit"/>
</form>
But it does not work It does not give error or anything. I have 2 Oracle PDK portlet having same code it works but this does not work.
Could you please guide me what is best approach of redirecting to another JSP in Oracle portal
I tried next_page ad hidden field but then it overwrite the another portlet next_page parameter.

I've seen some weird errors when people mix MyFaces and Sun JAR's together (although I haven't seen this one earlier).
First try removing the Sun JSF RI JAR's (jsf-api and jsf-impl) and see if it works. If not, then try replacing the h: components by t: components (Tomahawk), that is at least replacing h:dataTable and h:column by t:dataTable and t:column.

hi,
When you enter more than one partner for a particular partner function (for example, you define three different ship-to parties), you can select one partner as the default. During sales or purchasing processing, if you have defined multiple partners for a partner function, the system prompts you to choose just one partner. The system presents the default partner as the first choice in the pop-up window and it is must.

Personalizations Random behaviour.

Hi Guys,
I am seeing a strange problem, with a tactical question.
I have developed a stand alone custom stack layout region with a textInput field in it(CustomRN). By default the test Input field is set read only.
I have attached this region to other seeded region(SummaryRN) by personalizing summary region and adding a stack layout which extends CustomRN).
This summary region is part of many pages. Two pages I have personalized (Context Document : OverviewPG, at function level) to make editable the test Input field as the need is that only on those pages, text input field should be editable.
Now, the problem is that sometimes the field appears editable, sometimes it doesn't. By clearing the cache, field becomes editable. But when renavigate after some time, or some using some other responsibility, its again read only. This is quite random behaviour.
Any thoughts? I am working on Employee self service, Performance management module.
Another key question is: I have personalized the the customRN with context document as OverviewPG(as custom RN is now part of OverviewPG), and personalized at context Document as customRN itself too.
If a shared region is personalized at the container page level as well as shared region level also, which of these two personalization may take precedence?

That makes sense.
Now try moving the focus request and the key event generation to a separate bit of code which is called after the table has been displayed.

Hi,
After getting the parameter in the Page2.jsp, you need to parse the string for '<' and '>' symbols. You need to use the following code to use instead,
< = < or <
= > or >Then you can print the string on the browser.

You do not check if the modelType is null and
          if(modeltype.equals("Direct")) {
          out.println("in if");
          will result in a NullPointerException when it is null.

Implementing session timeout in JSP - - Urgent help !

Hi
I have a requirement where I need to write a session timeout functionality in a JSP such that the page is redirected to a different page if there is no activity for 5 min.
I tried the following :
1.On the onload of my JSP, i created a new session from the current request using the following code snippet :
          HttpSession pSession = request.getSession(true);
          pSession.setAttribute("loggedin","true");
          pSession.setMaxInactiveInterval(10);
2. Then on any action performed on the JSP, i called the collowing JS function before invoking the server side code.
/** function to check the user session **/
function fnChkSession()
     alert('Inside check session');
     <%
          try
               System.out.println("The value of the session var loggedin : "+pSession.getAttribute("loggedin").toString());
               System.out.println(" getMaxInactiveInterval() value is : "+pSession.getMaxInactiveInterval());
          catch (Exception e)
               System.out.println("** Inside the fnChkSession exception catch block **");
          if (pSession.getValue("loggedin") == null)
     %>
          alert('Session has expired');
          document.forms[0].submit();
     <% } %>
But when I execute this code ,even after 10 secs my session seems to be alive.I can retrieve the session attribute after 10s.
I also tried setting the session-timeout value in the web.xml. It didnt work.
Can anyone pls help me on how to proceed further on this.
Thanks

You are confusing java with javascript.
These two things are not the same.
The lifecycle goes something like this
1 - Request is made to server
2 - Java/JSP runs java code, produces HTML page
3 - java stops running
4 - html is sent to browser, and javascript starts running.
You cannot call java code from browser events (such as onload, onclick, onchange...) The only way to run java code again is to submit a request (normally by submitting a form, or clicking a link. )
If you want a javascript solution, in IE, use the window.setTimeout() method to execute some javascript code after a certain period of time.
A more generic approach would be to use the refresh header. Set the timeout for the refresh header to be 300 seconds. If the user stays on the same page for more than 5 minutes, it will redirect to the new page.
Hope this helps,

Redirection JSP not working in IE

Hi all,
I have a servlet with the following part of the code to redirect to an jsp page.
When I enter the correct username and password, and click "submit", it should redirect to my index.jsp page. It works fine with firefox, but in Inter
works fine with firefox. But in Internet Explorer(IE), if I click "submit" button, nothing happened, it just remain at the original page.
if(buttonType.equalsIgnoreCase("submit")){
if (username.equals("test") && password.equals("test")){
     url = host+"index.jsp";
     response.sendRedirect(url);
     return;
Thank you in advance!

JSP- Servlet- Same JSP - Urgent HELP!

I have a scenario as follows:
The JSP is a Login JSP which forwards the request to the Servlet to validate the Login info from the HTML. This I do by submitting the JSP page to itself & in the beginning checking if the Submit button was clicked, if yes, then I extract all the form elements by request.getPArameter(element name) & set in on the request using request.setAttribute() methods! The servlet uses the values by doing a request.getAttribute() & say, a validate User failure, the servlet ahs tor edirect user to the same Login.jsp page, but the second time, the "Submit" button value is still true, since the servlet forwards the same request, response & this ends in an infinite loop, of JSP calling Servlet, the User validation fails & the Servlets calls the JSp again, and so on.
How do I reset the HTML form element values in the JSP before forwarding to the Servlet? is there a request.setParameter() method? Or is there a way for the servlet to forward a new request & response to the same JSP?
Thanks in advance.

if the user is invalid.. redirect them to the error page and in the error page pu this javascript... It will refresh the page so the loop will not happen.
<script language="JavaScript">
var sec2count = "2"
var redirectpage = "Login.jsp"
function countdown() {
if (sec2count == "0") {
document.location = redirectpage
else {
sec2count = sec2count - 1
document.form1234.counter.value = sec2count
setTimeout("countdown()", 1000)
countdown()
</script>

Http 500 error when redirecting jsp pages

Possible to redirect JSP output?

Is it possible to redirect the output of a JSP either directly to a printer or directly to a File object? I would like to write a report template using JSP and be able to display it via a browser (so far so good, that's what JSP does) but I'd also like to take the same output that the JSP generates and either print it directly (as in printing many many reports without having to run each one in a browser and click the browser print button) AND to be able to email the report to a client.
Each of these means I need to redirect the output of a JSP. I couldn't find anything in this forum about that. Is this even possible?
Thank you in advance for your answers.

The problem with using a new URLConnection is that the current session is not applied to the JSP page as desired.
For those using Tomcat 4, which implements the Servlet 2.3 spec, this page describes how to replace the output stream of a servlet with your own.
http://www-106.ibm.com/developerworks/java/library/j-tomcat/
The example implements a character replacement mechanism. Using a filter and a wrapper. I modified this example to redirect the output stream to a file, which allowed me to then e-mail the output of a JSP. I did this by only using the wrapper classes.
Here are the relavant excerpts from my code
//Inside the servlet:
//{snip}...
String sFileName = "e:\\temp\\email\\temp.html";
RedirectTextWrapper rTW =
new RedirectTextWrapper(response, sFileName);
gotoPage(sAddress, request, rTW);
//{snip}...
//Supporting classes:
class RedirectTextStream
extends ServletOutputStream {
private OutputStream intStream;
private boolean closed = false;
public RedirectTextStream(String sFileName) {
try{
intStream = new FileOutputStream(sFileName);
}catch(FileNotFoundException e){
e.printStackTrace();
public void write(int i)
throws java.io.IOException {
intStream.write(i);
public void close()
throws java.io.IOException {
if (!closed) {
intStream.close();
closed = true;
public void flush() throws java.io.IOException {
intStream.flush();
class RedirectTextWrapper
extends HttpServletResponseWrapper {
private PrintWriter tpWriter;
private RedirectTextStream tpStream;
public RedirectTextWrapper(ServletResponse inResp,
String sFileName)
throws java.io.IOException {
super((HttpServletResponse) inResp);
tpStream = new RedirectTextStream(sFileName);
tpWriter = new PrintWriter(tpStream);
public ServletOutputStream getOutputStream()
throws java.io.IOException {
return tpStream;
public PrintWriter getWriter()
throws java.io.IOException {
return tpWriter;
}

Mozilla n' Firefox shows HTML source for JSP(URGENT!!)

Hi all,
I have made a web application with JSPs. It seems to work fine with IE. However, with Mozilla and Firefox, it displays the HTML source generated by JSP instead of actually showing the HTML page for that source.
I'm stumped because I haven't found any other msgs on forums with someone experiencing the same problem. Any help would be appreciated. I need to fix this urgently.
Thanks

Random blank pages with JSPs

I've written several web applications, and I've never encountered this before. I have a servlet and several JSPs. As I continue to run the application as I am developing it, I am having problems where a page will be blank. What I see is a URL with the servlet context plus a parameter for the page name that should be going to the servlet. If I click the back button in the browser, and do the exact same thing again, that post request is sent to the servlet, processed correctly, and a new JSP is dispateched to present a web page. That is, when I can't predict it, a page does not render because it seems as though the post request does not actually reach the servlet but this does not happen most of the time. I can't figure out how to debug it, since it happens at random moments on random pages. I'm running on tomcat 5.1. Any suggestions for how to debug this? My log for the application (created by log4J) shows nothing, nor does catalina.out or current localhost log file. Thanks.
Ken

No I didn't decide to revert back, I just wanted to see if by going back I would get blank pages again. And I did. My wife's iPad is now on Google and is working fine, so that does seem to be the solution, despite BT's Chat advisor claiming that it could not possibly be their DNS server.
Yeah, I will change the router's DNS if it's still OK in a few hours. I gave up with the BT HH a few days after installation when I got fed up of constant (hourly) WiFi dropouts. BT kindly sent me a replacement and that was even worse ; the HH really is junk, and I hate not having control over router settings anyway. I've always been happy with Linksys so went for an EA4500, which has been great. Oh, and I also have an old WRT54GS running DD-WRT as a wireless bridge to reach the parts of the house and garden that are out of range of the 4500.
Finally, thanks for your help.

Download a text file from JSP (Urgent Please!)

Hi,
I have a issue with this JSP, I need to download a txt file from my webserver to the pc client, the page shows the dialg box but appear the filename (list.jsp) of my jsp instead of the txt file.
If I click the save buton save the list.jsp page; if I click in the open buton, then appear again the dialg box and now appear the url (download.jsp?filename=...) and if I click in the save button now I can save my txt file in the local pc.!!!!
Any ideas ??
list.jsp --> is the jsp from the download.jsp is run.
download.jsp
<%@ page import="java.io.*,javax.servlet.*,java.util.* "%><% String filename = request.getParameter("filename");
response.setContentType("application/download");
String value = "attachment; filename=\"" + filename + "\";" ;
response.setHeader("Content-Disposition",value);
int iRead;
FileInputStream stream = null;
try {
File f = new File("C://test//" + filename);
stream = new FileInputStream(f);
while ((iRead = stream.read()) != -1) {
out.write(iRead);
out.flush();
finally {
if (stream != null) {
stream.close();
%>

Maybe try no quotes around the content disposition header?
Also, I'm not sure that application/download would be the best content type, maybe "application/octet-stream" instead. You should also probably explicitly set the Content-Length header to the file size.

Displaying an Image in an Excel Spreadsheet with JSP - URGENT

Hi Peoples
I can transfer the table I am using in to excel with JSP by doing:
<%@ page contentType ="application/vnd.ms-excel" %>
this works fine, though I have an image that sits within the table that I want to be displayed as well.
Can this be done?? If so how???
Thanks
