Please help with "500 Internal Server Error"

Hi all,
I get a "500 Internal Server" error when doing some processing with a Java program that makes HTTP calls into an application API deployed as WAR file on a OC4J midtier installation. The process works fine until I get a "500 Internal Server" after about 100 transactions. I can see reference to the 500 error in the Apache access_log, but that is it - no other references whatsoever in any of the logs (OPMN, OC4J, Apache, etc.).
Can anyone point me to some sort of "500 error troubleshooting guide" or have any suggestions as to how to track the problem down?
Thank you.
Anton.

Hi,
Thanks for the reply! And yes its very frustrating. There is no other reference to this error - and I have the app and all Oracle components (oc4j & Apache) at their maximum log level.
I have logged a SR with Oracle and off course their first response was that it "must be an issue with the 3rd party app". Needless to say the 3rd party vendor suggests I speak to Oracle...Anyway I am still working with Oracle on the SR.
I have in the meantime upgraded to 9041, but I still get the same. I will try 9042 next. I have also started a "Plan B" workaround in my code...
Thanks for the sympathy and any other other insights still most welcome...
Cheers.
Anton.

FOP PDF Printing Fails with 500 Internal Server Error in APEX 4.1

Hi,
We have Oracle Application Server 10.1.3.5 (Apache + J2ee) installation in our environment. I configured Apache FOP for Apex 4.1 running on Oracle 11.2.0.1 database using" Section 5 - Installing and Configuring Apache FOP - http://www.oracle.com/technetwork/developer-tools/apex/application-express/configure-printing-093060.html document". I am getting "500 Internal Server Error
Servlet error: An exception occurred. The current application deployment descriptors do not allow for including it in this response. Please consult the application log for details."
Do I need to configure Apache FOP only using Standalone OC4J containers as mentioned in the document instead of using j2ee containers installed as part of OAS 10.1.3.5 install? If so, any idea why this restriction?
Thanks in advance for your help.
Regards,
Lavanya

Thanks Hussein for your response.
Do you have proper entry in the hosts file?I do have the correct entries in both host and guest OS. As I mentioned, I'm able to ping in command prompt both linux guest (DNS) name and ip address. It is just the login page load. It could be not just R12...may be any other web page as well...
I don;t know how these DNS Server name is resolved and so on..this networking stuff in windows 7...it may be irrelevant to this forum...but chancing my luck if someone had this issue in the past.
I believe the main issue with the ping, so once this is fixed you should be able to access the application (assuming it is up and you can access from other machine -- If I understand you correctly, I believe you did from XP).Yes..the same config works fine in XP.

Hi,
In KM Content goto /etc/xmlforms/km.appl.xmlforms.xfbuilder_core.jar and download the file to local files system.
Now open the jar file with winrar/winzip and open META-INF folder, there you should find SAPPortalsCertificate.SF and SAPPortalsCertificate.RSA files.
If these files exist in META-INF folder, then you jar is signed and if not unsigned. For security reasons classloader does not allow to open unsigned jars as some other jars in classpath are signed.
So if these files not present in META-INF folder, then replace the corrupt km.appl.xmlforms.xfbuilder_core.jar file with file that works on some other server.

What does it mean? 500 Internal Server Error? Is this a Goog;e thing?

When I open Firefox, the page is blank with 500 Internal Server Error at the top. I think it might be an issue with Google, because I can access sites from the address page, but no access to Google. Has anyone else had this occur?

Does is still happen in Firefox Safe Mode. See [[Safe Mode]].
If so, it's probably being caused by an add-on.

Google search homepage lost 500 internal server error?

always used google search as homepage over the last few days it just loads with 500 internal server error and I cant reset it even when restoring default and trying again cannot even get to any google webpage??

Start Firefox in Safe Mode to check if one of the extensions or 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.

Check the connection settings.

C:\Jdevstudio successfully
2. Then i created the untitled1.jsp page ---> only showed Hello world and save
3. the Embedded OC4J Server compiled successfully ..i thought this meant nothing wrong with the code.
Successful compilation:0 errors, 0 warnings..
4. But when i looked into the Embedded OC4J Server-Log
i found the error :

I got less error showing:

This still caused 500 Internal Server Error
6. I still did know the real problems then i read the installation guide of jdev
is it necessary to set the JavaHome in C:\Jdevstudio\jdev\bin\jdev.conf
or do i need to set ORACLEHome in this file
7. from the log file the server called Jdk under Jdevstudio\jdk\bin\javaw.exe -jar
it seemed fine...
8. Anything wrong with admin.jar....
9. is the problem from setting not setting jdk (javahome) or admin.jar...or OC4J problems please help
i would appreciate you help
thank you

OAM 10.1.4.3 integration with EBS- 12.1.3 gives http 500--Internal Server Error on login

Hi,
We are integrating E-business (12.1.3) with Oracle Access Manager (10.1.4.3) using Oracle E-Business Suite AccessGate[1.2.2].
On trying to login (after submitting credential) to the application we are getting the below error.

Please help me if anybody has faced this issue previously.

Hi,
Thanks everyone for the response.
Doc ID 975182.1 for EBS-OAM integration is being followed.
We've collected the HTTP traffic but it shows the same 500 internal error and class cast exception. The deployed access gate also shows the same error when in debug mode.
Any pointers would be helpful.
Thanks.

Please help with "500 Internal Server Error"
