Same JSP/Servlet is executing again and again

Hello,
We have some JSPs which do a lot of processing and is 'alive' for a long period
of time. If we use the JSP with small amouts of data, it is fine. But when we
use the JSP with lot of data, it seems to 'go in a loop'.
It is processing the data again and again and again and brings down our server.
We do not think it is the code that is wrong - as it processes perfectly if the
data is small or when our server is not busy. This problem happens if the data
is lot and the server is also busy. The JSP seems to be executing again and again.
Is there some type of 'refresh' logic in weblogic that refreshes the JSP/servlet
and makes it 'execute' again and again.
We are using WL 6.1
Thanks,
Oleg.

Hi Oleg,
Could you tell us how you find out that there is an additional request?

Thank you Varad and Slava,
We don't use plagin for iplanet,
but our problem is very similar:
Weblogic generate additional request if the previous request toservlet/jsp is
taking long time.
Where I can configure JSP timeout to fix this problem?
Thank you very much.
Oleg.

Hi Oleg,
Are you using weblogic plugin for iplanet webserver ?
In weblogic server 6.1 sp3 there is a problem with this plugin. It would
generate
additional request if the previous request to servlet/jsp is taking more
than
the configurable timeout set in the obj.conf file of iplanet webserver.
This plugin problem is fixed in wls6.1 sp4.

How do you know that a JSP goes into a loop?

What load is considered to be high/low for you
application? Are you running a load test?
Is there some type of 'refresh' logic in weblogic that refreshes
the
JSP/servlet
and makes it 'execute' again and again.Normally Servlet/JSP enters service() method when
there is an incoming request. It should not be happening
at JSP's will.

How to compile jsp project on the plateform of Myeclipse and jboss
hi :-) this is not eclipse forum and not that sure about your problem but i'll try to answer :-)
i'm not sure how you create your war but there something wrong with your web.xml. kindly check it :-)
by d way, you can deploy your project in my-eclipse by
- right click on the project then select my-eclipse > Add and Remove Project Deployment's
- a new window will open and you can now configure how you deploy your project :-)
other alternative edit your jboss-service.xml then put something like this
<attribute name="URLs">deploy/, file:/D:/workspace/deploy</attribute>
(note, change the path according to your needs)

How can I call EJB from JSP/Servlets in iWS?

Hi!!
My JSP/Servlets are on iWS, and I deploy EJB on iAS.
In this case, I don't know how JSP/Servlet call EJb on iAS.
I'd like to know how I can set JNDI name in JSP/Servlet on iWS.
I will thank you if you give me a simple example source using JSP/Servlet
and EJB.
Thanks in advance!!!
- Park-

Park,
Why Are you running your JSP/Servlets in iWS instead of iAS? For whatever
reason,
look at the Converter sample from iAS. You will be doing RMI/IIOP in this
case and the sample explains in detail what to do.

How to execute again the JSP codes

Dear Experts,
I am having trouble to execute again the JSP codes in my abc.jsp page. The sequence of the codes are:
[ JSP codes ]
[ HTML codes]
My JSP file is selecting from DB2 and display the results on the same page. The selecting is depending to the selection in the combo box and included the selection into the SQL statement.
The problem is when I change the selection at the combo box, how can I refresh the page and fill in with the new results from database by selecting with the new keyword.

You will have to do an onChange handler for the select box, that simply submits the form, and the action would be the current page.

ViewObject LOV query is executing again and again..

Hi Experts,
Currently in my application VO has one LOV component
DeparmentVO - countryID (LOV) pointing to the CountryVO
Where CountryVO is a query based and it depends on the user session language "Select countryID, country from Counties where language=:language
Now application works fine, however whenever the user launched the page the countryVO query is executed again and again and it is not cached. In the DeparmentVO view accessor the is there any way we can specify the CountryVO to be taken fro cache? Or is there any configuration that we need to do inorder to run the country query only once per session?
Looking forward you advice on this.
Thanks

Hi Timo,
Our jdev version is 11.1.2.1
We have the page which shows the department table each record has the country LOV.
After the login the user can view the page at that time the query is executed, after that he may visit some other page and then come back to the same page then again it is executed. The CountryVO list is based on the language so it needs to be load only once per session in my case to optimize the performance.
Thanks

Try removing and then reinstalling the Apple software using these instructions.
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7
The above containes a link for XP. Also. make sure you install the correct Apple software, It comes in 32 and 64 bit and you need the one that is the same as the computer OS

First, you posted in the Mac App Store forum which are apps for the Mac OS X, not iOS devices.
You do not need to re purchase your apps. Connect your iOS devices to your computer, launch iTunes. From the menu bar click Apps then click Sync

When i active my mac pro all i get is a white screen and it loading .. and when it fully loaded it turns off and the same thing keep on happening again

when i active my mac pro all i get is a white screen and it loading and when it fully load its turn off , and it keep on doing the same thing for hours

Hi Shahenaz,
It's a little difficult to understand exactly what's going on with your mac based on the description you gave. Is there anything else you could add? Is it stuck in a reboot loop? Or is it just showing a white screen forever?
I had pretty much the same problem a few days ago, and was worried my mac was screwed permanently, but I got it fixed up no problem!
Follow these steps to try and troubleshoot/fix the problem.
1. Boot into OSX Recovery Mode
First, turn off your Mac. If it isn't responding, or is stuck in a reboot loop, just hold down the power button until it turns off, and you hear the fans stop. Then boot it while holding the Command and R keys. If it successfully boots into OSX Recovery Mode, continue with this step. If not, skip to step two. (My Mac couldn't successfully boot into the recovery mode, so I had to go to step 2)
Select "Disk Utility" from the list of options, and find your built in hard drive from the list on the left. Usually there are two listings/names for your drive. The first should be something like "500GB longchainoflettersnumbers Media". Then the one below will be a little easier on the eyes, named Macintosh HD, if you haven't changed its name. That's the one you want, click it.
Now go to the "First Aid" tab. Click on the "Verify Disk" button in the bottom right corner, and let it do its thing. Once that's done, hit repair disk, also in the bottom right corner. If your disk is corrupted, you may need to run the repair process several times, before it comes up completely clean.
Once this is done, select Shut Down from the Apple menu and, once your Mac is completely off, turn it back on like normal. If it works, great. If not, proceed to step two.
2. SafeBoot
Sometimes, when a mac is acting up and doesn't want to start, all it takes is a safe boot, followed by a regular restart. Or maybe you recently installed a program that either has malicious or errored coding that's causing your troubles. This is where Safe Boot comes in.
Turn off your mac, and reboot it while holding Shift. (If you want to see the process that's going on in the background, boot while holding Shift, Command, and V. This will enter something called Verbose Mode).
If it boots successfully into Safe Mode, great. If you believe that there's a particular program that you recently downloaded that might be causing your trouble, now's the time to delete it. If not, just reboot normally and see if it works! If it doesn't, or if your Mac didn't even Safe Boot like mine, proceed to step 3.
3. Fsck!
For this step, you're going to be booting your mac into Single User Mode. I'm not going to go into details as to what this step does, but it works for some people. Here are the steps.
Turn off your mac, and reboot it while holding Command and S. The screen should go black, and you'll see some white text run across the screen, wait a few seconds, until you see the command prompt. Now type
fsck -fy
and hit the Enter key. This will run a series of system checks, which could take a few minutes. Be patient on this part. Once it's done, it will show one of two messages:
1. "The volume (your Mac) appears to be OK
or
2. "File System Was Modified"
If you got message 1, type reboot and press Return. Hopefully your computer works after this - if not, proceed to step 4.
If you got message 2, run the same command again until you get message 1. If it doesn't seem to be working, turn off your system and proceed to step 4.
If you couldn't even boot into Single User Mode in the first place (like me), go to step 4 anyways.
Step 4: Reset the NVRAM
The NVRAM is another kind of RAM that stores data like the computer volume you had set before you turned it off, or the screen brightness, resolution etc. This memory is saved, unlike with regular RAM. Resetting it isn't harmful to your system, it will just put your screen brightness, volume, etc. to defaults.
Turn off your Mac, and reboot while holding Command, Option, P, and R, and continue holding them down until you hear the computer restart again.
I can't really explain why to do this step, I just know it works for some people, and seems to be what unbricked my MacBook Pro. If none of these steps, fixed your Mac, well the situation is looking pretty grim. Try setting up a meeting with a Mac Genius at your local Apple store. However, I know that many other people with these symptoms ended up having a logic board failure. Apple can swap out your logic board for a new one, but the price is pretty hefty, somewhere around $300 I believe.
Well I wish you luck, I hope this helped you!

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>

How to get 'exit event' script to execute again when form file with saved data is re-opened?

I have created an Adobe Dynamic XML Form using LiveCycle Designer with many fields / subforms that are ‘visible’ or ‘hidden’ dependent upon the options selected from various Drop-Down Lists. The form has also been save-enabled. Users can successfully complete the form and save a copy with the data that has been input.
The problem I have is that when the saved file is re-opened the ‘hidden’ fields / subforms which were previously made visible by selection of the appropriate options from the Drop-down Lists are now NOT displayed. However if you make the same selections from each of the Drop-down Lists AGAIN the hidden fields / subforms are displayed and do contain the data that was entered.
The problem appears to be that the script which determines whether a field / subform is ‘hidden’ or ‘visible’ is an
<event activity="exit" name="event__exit">
which is followed by
if (this.rawValue == "0")- (i.e. the value of the Drop-down List)
sfCompanyDetails.presence = "visible";
sfRecruitmentAgency.presence = "hidden";
etc, etc
and, therefore, it is not executed again when the saved file is re-opened.
Can anyone please advise how to achieve this?
