html:submit causes HTTP Status 500

Hi guys,
I did some modification to my struts project and apparently I am getting the notorious message below. I removed the tags:
<html:submit> and </html:submit>
And the project works! What is the reason this is happening and how can I use those tags?
* I checked to verify and my struts-html-el.tld is located under the /WEB-INF
Thanks

HTTP Status 500 message when attempting to open Financial Report.

In a new 9.3.1 installation (BI, Essbase, HFM, Planning) I am unable to run Financial Reports in Workspace. As a test, I have created a simple report, using Studio, which has only boilerplate text - no grids or anything else that requires a DB connection. The report previews fine from the Studio client but when I attempt an HTML preview or when I attempt to run the report from within Workspace, I receive an HTTP Status 500 error in the right panel in Workspace. Below is the text of the error. I am using IIS 6 with Tomcat. My troubleshooting effort have been around IIS and BI configuration. I am able to open Web Analysis documents without any trouble. Any suggestions you may have would be appreciated.

Hi again Ramana,
Did you try any of the following:
1.) Delete Tomcat cache with the following steps
Stop Tomcat.
Remove the folders from <Tomcat\work\Catalina\localhost> directory.
Start Tomcat. (it will delay a few minutes)
The cache will be recreated automatically.
2.) Redeploy Explorer application with wdeploy tool (Location: <install_dir>\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\wdeploy)
Syntax
wdeploy <WEB_APP_SERVER> [-D<PROPERTY>=<value>] <ACTION>
Example
-- Undeploy
wdeploy tomcat7 -DAPP=explorer undeploy
-- Deploy
wdeploy tomcat7 -DAPP=explorer deploy

Flickr Server Error - HTTP Status 500 - how to fix?

Hi,
Just upgraded to Photoshop Elements 11 on a x64 Dell running Win7. When trying to share photos using Flickr (which worked previously), I get the following:
Any idea what I can do to fix this? I've tried resetting accounts in Adobe Partner Services, Clearing Online Service Data, and refreshing the list of services - but makes no difference.
Any help very much appreciated,
Dan.

Hi,
Thanks - I've cleared my browser cache, and tried all the other things available here too, a couple of days ago:
http://kb2.adobe.com/cps/403/kb403064.html
When I tried it, it made no difference. Ironically, just using the Flickr service today 'just works'. Server side, as you say, so maybe something got restarted / fixed?
Given the entire forum web site wasn't accessible yesterday (and that appears to run on Tomcat, too) - perhaps the restart of the one is linked with the restart of the other.
Anyhow - problem solved - thanks for your support!
Dan.

java.lang.UnsupportedClassVersionError: Bad version number in .class fileThe class is compiled with a JDK version which is newer than the JRE version used to run the class. To solve this, just clean up your Java environment and align the versions. You can get version information of the Java compiler using javac -version and of the Java runtime using java -version.
That said, this problem is actually not related to servlets. You didn't get a root exception of javax.servlet package. You just got a root exception of java.lang package, which basically makes it a Java SE problem. Questions related to those actually belongs in the 'New to Java' forum.

HTTP Status 500 error

We have a form in Form Manager that sends us back to the login page after clicking on the submit button. This usually happens when it takes us more than 1 hour to complete the form.
When I try to login again and click on the link to open the form, I get this message on the right side of Form Manager:
HTTP Status 500 -

We suspect that this is a timeout issue. We already changed the web.xml file and increased the session-timeout to 5 hours but the error still occurs. Please help. Thanks.

Hi Melissa
I have asked Adobe numerous times about how to modify the default timeout in Form Manager. The response has always been that there is no way to do this.
I'm not trying to dissuade you from trying, and it would be great to find a solution, but I wouldn't hold out too much hope :-)
This comes down to a training issue - if the user is going to leave the form for any length of time, they should save the form as a draft.
Good luck...

PS. I haven't tried this yet, but I suspect that this will be much easier to tweak in LiveCycle ES. So another option is to consider upgrading.

Could you kindly help me.
Thanks in advance for your help

Hi Paolo,
which APEX version do you use?
There are only a few reasons that might lead to the behaviour you describe. These are
- configured header size for Tomcat Connector is too small
- configured character encoding for Tomcat Connector doesn't fit for APEX (you need UTF-8)
- you don't have the required version of OWA_UTIL in your XE if you upgraded to a more recent APEX release (e.g. APEX 4.0)
Have you configured the Tomcat's HTTP Connector to use the appropriate header size and character encoding?
(see {thread:id=2174509})
If you've upgraded your XEs APEX, e.g. to 4.0, you also have to update the OWA_UTIL in your XE. APEX versions from 3.0 onwards require at least 10.1.2.0.6, which is the version provided in the installation package. You may just update to that version by changing to the subdirectory owa of your APEX installation package and running
@owainst.sqlas sys (just like in the steps before).
You can check if you have the appropriate version of OWA_UTIL installed by running
select owa_util.get_version from dual;In addition you may also want to check if you performed all steps of this small [url http://www.oracle.com/technetwork/developer-tools/apex/upgrade-apex-for-xe-154969.html]HowTo for the upgrade of APEX in XE databases.

What can I do about http status 500 error report?

I have Windows and want to log in to a bank website. I click the Log In button and get this message:
"Http status 500" and that "The server encountered an internal error () that prevented it from fulfilling this request." and "Path webClient.passmark.login does not start with a "/" character" and "he full stack trace of the root cause is available in the Apache Tomcat/5.5.23 logs."
I have tried the "secure Connection failed" troubleshooting without luck. What can I do?

Does a direct link to the login page work?
*https://secure.ally.com/allyWebClient/login.do
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.

2 users can't login - HTTP Status 500 - on Teaming 2.0

I have 2 user that can't login to Teaming 2.0. They get this error: "HTTP Status 500". Even if I enter a bogus password for them the "HTTP Status 500" error occurs. I use LDAP authentication to eDirectory. These users DON'T have duplicate objects in my tree. In eDirectory they have first name, last name, full name, phone number and email address entries. All other users can login. Where are the Apache Tomcat/6.0.18 logs on a SLES 10 install of Teaming 2.0? There are log files in /opt/novell/teaming/

You need to be sure that it is not an LDAP problem... the best way is to start from LDAP to investigate. Enable the LDAP trace on eDir with imonitor, during the teaming login. Also you can use ldapsearch to have full details on the accounts in order to compare them with a working user (a space somewhere, an additional attribute, etc...).

please help me out, i have a release to QA today

findbykey method failed because it tried to access 0'th element of the array/list with size 0?
maybe acegi filters out elements to be returned so it returns empty collection and some logic knows that there should be elements returned so tries to access first element on array/list but there is nothing since acegi has filtered data out?

HTTP Status 500 Error java.lang.NullPointerException on BO 4.0 SP2

The installation of 'SBOP BI Platform Servers 4.0 SP02 Patch 5' didn't affect this problem, it still has the same error.
BusinessObjects XI 3.1 is running without problems on that server.
Any help would be very appreciated!
Thanks in advance.

Hello together,
I could fix this issue without any reinstalling of tomcat. I had the same problem after installtion of Patch 9 of SP2 for BOE 4.0.
Directly after the installation I changed the session-timeout parameter in some web.xml's because it was requested by our customer. Because I wanted to have a good documentation of those changes in the web.xml's I created a bigger comment in these files.
First I got 404 errors after that - to solve this I followed Knowledgebase article [1639813|https://websmp230.sap-ag.de/sap/support/notes/1639813] but first it didn't help.
So the before mentioned bigger comments seemed to be a problem (or maybe the special characters in there) because after shortening these comments and restarting SIA and Tomcat the 404 error disappeared and suddenly the above described 500 error occured.
After that I changed the Tomcat's localhost directory to localhost.old during downtime of Tomcat (as recommended by Lukas Kostrab). localhost was newly created but it didn't help either.
So last but not least I redeployed tomcat following article [1639813|https://websmp230.sap-ag.de/sap/support/notes/1639813] (wdeploy.bat tomcat6 u2013DAPP=BOE deploy) and started Tomcat and SIA again. I decided to wait a little bit longer with trying to start CMC - maybe 15min - and suddenly it worked.
So in conclusion I would say:
- check any changes you made in any config-files (like e.g. web.xml) and shorten them or remove special characters
- stop SIA and Tomcat
- rename localhost directory (or copy and remove) so it will be recreated at startup of Tomcat
- if that doesn't help check tomcat config according to article [1639813|https://websmp230.sap-ag.de/sap/support/notes/1639813] and redeploy tomcat as mentioned in that arcitle and be a little bit patient
Hope this might help some of you.
Best wishes
Marie
