JSP Flush not working on submit to page

I have a page that gets called from another with a badic submit button. In the second page I flush the stream and then wait 10 seconds. The problem is that the browser does not show the response until it is done getting the data and then the whole page shows up. What gives? BTW If I hit the refresh button on the page then it works fine.
Code below:
<html>
<head>
<title>This is the title</title>
</head>
<body>
here it is.
</body>
</html>
<%
out.flush();
Thread.sleep(5000);
%>
Response after

The browser doesn't have to synchronize itself with your output, and there's so much buffering between your JSP and the browser that it couldn't even attempt that anyway. Also, it's quite common that the browser won't display the page until it has received it all, especially if there are tables involved, because it doesn't know how to render the first part until it sees what comes later. I can't imagine why you would want to stall the output, the Internet is slow enough as it is.

OC4J JSP Debugging not working for all the jsps

Hi,
Initially I was not able to debug jsps using Eclipse and OC4J. The jsp debugging started working once I made the below changes:
1) global-web-application.xml is modified
Changed the attribute development="true" in orion-web-app
Added the below init param for the JspServlet
<init-param>
<param-name>debug</param-name>
<param-value>class</param-value>
</init-param>
If the jsps are present in a sub directory under the webcontent none of the breakpoints are working. I am still be able to view the jsp pages on the browser.
Tools: Oracle 10g Application Server Standalone version(10.1.3.5.0), JDK5, Windows XP, Eclipse Indigo
Project Structure:
Test (Eclipse Dynamic Web Project)
-WebContent
Sample.jsp ( Breakpoints are working)
-subF (Folder)
SubSample.jsp (Breakpoints are not working)
-WEB-INF
web.xml
Debugging worked for http://localhost:8888/Test/Sample.jsp
Debugging not working for http://localhost:8888/Test/subF/SubSample.jsp
Any help is highly appreciated.

This tells there is not enough main memory (not disk space) for the program to run.
- You can look the dump in ST22, it will have suggestions on increasing the ROLLAREA??, you can forward that to Basis.
- Most likely you will not have any more memory to assign so the above may not be feasible. Try to rework your query so it works with less data.

Response.sendRedirect("abc.jsp") is not working

Hello,
I deployed my web application(jsp with business components) on AS 902.
Web cache is running on port 80.
Apache is running on 7778.
To pass request i use,
mod_proxy.c in http.conf. and
<virtual host> for my application, to get required url.
It is running fine, But response.sendRedirect("abc.jsp") is not working properly. It redirects the request to apache directly and skips web-cache. Also it changes url for the page given in method.
While the same application was running ok on v 10222a. That version handle this method properly.
how to remove this error ???
Plz hurry up. Our product is ready for launching on 9iAS. It is final testing.
Thnx.

Tahir,
What is the exact error message you are hitting.
Are you able to use web-cache with other examples.
Can you try testing it the the webcache demos that are part of ojspdemos.ear under /j2ee/home/demo.

I upgraded to version 9 from version 8. The following items do not work properly - menu, home page, navigation bar, wheel click. I backed up to version 8, and none of this stuff works right. How do I fix this?

When I open Firefox, the bookmark menu is a little tab in the upper left corner. If I go to view and un-click bookmark menu and then view, click it, the standard menu bar shows up. The Back and Forward buttons don't work. The navigation window does not show the URL of the current page. When opening, the home page does not come up. The wheel click works on the bookmark bar, but not within a page. The menu (file, edit, etc) does not work after the first page. Version 8 worked well. When I upgraded to version 9, all this trouble started. I backed up to version 8, but the problem persists.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
*https://support.mozilla.com/kb/Safe+Mode
Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

I updated to latest Safari version (7.0.4) but the problem persists.

One problem is that you write into the output stream from an action method and don't know what's already in the output stream. Once there is one byte written to hte stream (which you can't know from inside the action method) the pdf stream does not behave as you think it would.
Next thing is that you use createRootApplicationModule but never release it. This will get you out of resources error eventually.
A better approach would be to put this code in a servlet and stream the report from there. In the servlet you have control over the output stream.
Check my blog http://tompeez.wordpress.com/2011/12/16/jdev11-1-2-1-0-handling-imagesfiles-in-adf-part-3/ where I show how to serve images from a servlet which can even use the application module pool from the application (no need to use createRootApplicationModule at all). All you have to do is to exchange the part where I get and stream the image data to your needs.

JSP compenent not working in mozilla and firefox

Hi Experts,
We have made a portal component with JSPs. And assigned it to anonymous page on our portal.
Same is working fine with IE. However, with Mozilla and Firefox it gets distorted.
Anyone knows whether mozilla supports JSP pages or not?
Is there problem with Support pack?
I am using EP 7.1 and SP 10 for the Mozilla Browser version (3.6.25 and 8.0.1).
Your helps will be appriciated.
Regards,
Chitra

Dear Chitra
Please check Product Availability Matrix in service market place to verify the compatibility for accessing JSP in mozilla,
I think it should work in 3.6.25 but not sure about 8.0.1, please check and verify in SMP
Best Regards

Out.flush() not working

I can't get the out.flush to work. The page is paused until all values are finished then it is displayed. Here is my example code.
<pre>
import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class MyTest extends HttpServlet {
     public void init(ServletConfig conf) throws ServletException {
super.init(conf);
public void service(HttpServletRequest req, HttpServletResponse res)
throws IOException {
// res.setContentType("text/html"); //this nor the one below works
res.setContentType("multipart/x-mixed-replace;boundary=\"boundary\"");
PrintWriter out = res.getWriter();
for(int x=0;x<3;x++){
     out.println("<br>x = "+x);
     out.flush();
          try{
                    Thread.sleep(1000); //in milliseconds - 1000 milliseconds = 1 second
               catch(InterruptedException ie){}
</pre>

You were hoping that the output of the servlet would be sent piece by piece to the client browser as you generated it? That is not how it works. Nothing is sent until you return from the service method. It is possible to do what I think you were hoping, but you have to work with the browser and have it refresh periodically. I have seen examples of that but I am not competent to try to explain it.

JSP/Servlets not working after upload

I have a JSP file and some servlets that work fine on my PC running Tomcat.
I just uploaded them to my web server (which supports servlets/jsp and has apache web server running), but they do not work. The jsp file does not run, it just displays the source code.
Strangely, the support people at my server say the jsp files run ok when they view them. But when I view them from my browser it just shows source code.
Do I need to configure something in my program? Or is it a server problem?

Very hard to help without seeing the page - the answer is in the code :-)
Can you please point a link to your page?
Are you sure you uploaded all the image files, and that the paths to the images are all correct?

Sites with .jsp extention not working completely

websites having extension .jsp are not showing propperly

Normally, when a webserver uses JSP, they instruct Firefox that the content type of the page is text/html, so Firefox doesn't treat those .jsp pages differently from other server technologies.
Could you provide a link to a page that is not showing properly and describe how it differs from what you expect?
More generally:
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
Alternately, you also can clear Firefox's cache completely using:
"3-bar" menu button (or Tools menu) > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now"
If you have a large hard drive, this might take a few minutes.
(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:
* right-click and choose View Page Info > Security > "View Cookies"
* (menu bar) Tools > Page Info > Security > "View Cookies"
* click the padlock or globe icon in the address bar > More Information > "View Cookies"
In the dialog that opens, you can remove the site's cookies individually.
Then try reloading the page. Does that help?

JSP-Editor not working properly

Hi everybody,
I am working with ISA5.0 and NWDI. I have checked out the Web-Module Project crm/isa/web/b2b.
Now I would like to modify JSP-Files. Unfortonately the JSP-Editor is not working properly.
The JSP-Editor cannot resolve references to Tag-Libraries like
<%@ taglib uri="/isa" prefix="isa" %>
Furthermore I get Errors with JSP-Includes
<%@ include file="checksession.inc" %>
The JSP-Editor does not show any other compile errors until the above mentioned errors are resolved.
So the JSP-Editor does not help with compile errors.
I have tried to use Lomboz instead, but due to the modularization in ISA5.0 and NWDI (ie the Taglibraries are defined in a separate module) I did not get it to work either.
Does anybody have experience on how to get the JSP editor to work properly?
Thanks for your help,
Andreas

Highlite the clip in the timeline, control click on it and choose "send to soundtrack as an audio file project" in the pop up menu. Don't do an "open with editor". This should work.
If it doesn't and it's just the one clip, you could launch Soundtrack and then open that clip as an audio project . . . don't do a open with editor, just open it directly. Make your adjustment and save over writing the file with the new audio. You may want to copy the clip first as a backup. When you open your FCP project, you'll have to re-link the clip. Once you do it will show up with the new sound.
