500 Internal Server Error - Web Dynpro Content Administrator
Any help would be really appreciated...
I was trying to create/Maintain JCo destions on Web Dynpro Content Administrator caught up with the 500 Internal Server Error
Error Summary
While processing the current request, an exception occured which could not be handled by the application or the framework.

To facilitate analysis of the problem, keep a copy of this error page. Hint: Most browsers allow to select all content, copy it and then paste it into an empty document (e.g. email or simple text file).
For further information about the Web Dynpro error page, error analysis and a description of well-known error situations, see SAP note 1113811.
Root Cause
The initial exception that caused the request to fail, was:
java.lang.NullPointerException
at com.sap.tc.webdynpro.serverimpl.wdc.sl.SystemLandscapeFactory.checkStatus(SystemLandscapeFactory.java:869)
at com.sap.tc.webdynpro.serverimpl.core.sl.AbstractSystemLandscapeFactory$1.checkStatus(AbstractSystemLandscapeFactory.java:310)

at com.sap.tc.webdynpro.tools.explorer.JCOConnectionsDetails.addJCOClientToList(JCOConnectionsDetails.java:750)
... 73 more

Possible Reasons:
1. Some fields for the backend system used to setup the JCO destination are not updated properly (i.e.
empty) in SLD.
2. Ensure that the SLD is setup properly. Click on the u201CTest Connectionu201D to check that the SLD is up and running.
Check section "NullPointerException in the trace when maintaining JCO destinations" in below SDN document:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/f3f93ee7-0c01-0010-2593-d7c28b5377c2 (Adaptive RFC- Troubleshooting Guide)

Thanks in advance,

Hi,
We were also having the same problem; but we couldnt find a specific solution for that problem.
But when we upgraded the ESS support packages to SP13 for some other reason this issue was also got resolved.
May be helpful i guess.

500   Internal Server Error : java.lang.NoClassDefFoundError in XI - SLD

Hi Friends,
We have upgraded the NW2004s java sp level from SP 04 to SP 05. But after doing so we are getting the following error while accessing the System Landscape Directory from the following link
"http://host:port/rep/start/index.jsp"
The error description is as below
"500   Internal Server Error
Web Dynpro Container/SAP J2EE Engine/6.40
Failed to process request. Please contact your system administrator.
Error Summary
While processing the current request, an exception occured which could not be handled by the application or the framework.
If the information contained on this page doesn't help you to find and correct the cause of the problem, please contact your system administrator.
Root Cause
The initial exception that caused the request to fail, was:
java.lang.NoClassDefFoundError: com/sap/lcr/pers/jdbc/CRQMappedJdbcJ2EEPoolPersistence
    at com.sap.sld.wd.main.MainView.checkHealthyServer(MainView.java:423)

Correction Hints
It can't be determined from the exception chain, which class loader failed to load the above class. But at least the class loader of the current application does not contain a resource with name 'com/sap/lcr/pers/jdbc/CRQMappedJdbcJ2EEPoolPersistence'.
If I click on the SLD onthe SAP Netweaver - Exchange Infrastructure, I am getting the above error.
Pls help me to solve this problem.
Thanks in advance
Purnendu

Hi Sridhar,
Thanks a lot for your reply.
I can launch the transaction SXMB_IFR. It works fine. I got the XI frontend with Exchange Infrastructure Tools.
But when I click on the SLD I am getting this error.
I have also tried to open the http://<SLDserver>:<port>/sld link. But this is also giving me the same error.
I have checked the SLDCHECK transaction.
I am copy/pasting some part of the Check result for reference.
""Use transaction SLDAPICUST if you wish to maintain the SLD server access data
Launching the SLD GUI in a separate browser window...
=> Verify in the browser GUI that the SLD is in a healthy running state!
Calling function LCR_LIST_BUSINESS_SYSTEMS
Retrieving data from the SLD server...
Function call returned exception code     4
=> Check whether the SLD is running!
Summary: Connection to SLD does not work
=> Check SLD function and configurations""
I have checked the following thread
XI-SLD & IS configuration
But the solution provided in the thread "configure the hostname without any domain with transaction SLDAPICUST" doen not work.
By the way how to check whether SLD is running or not.
Thanks in advance and warm regards
Purnendu

ESS- 500 Internal Server Error

hi all
some of the ESS users getting when they check on the my messages or leves
"500 Internal Server Error -WEB Dynpro Container /SAP J2EE Engine"
can some one help me tko identify and resolve this issue..
Regards
Buddhike

This is not a specific error. It can often times be cleared up by simply refreshing. It could be that the portal was to slow to connect, it could be that the backend was too overwhelemd to connect, it could be several things. That's why I suggested having your BASIS folks look into it. In one case recently, ours was simply that the server was not tuned correctly and was "missing" connections. It might be something fairly simple for you.

I got the 500 internal server error while deploying the application to server.
I tried to find the log file at usr --> SAP --> SID --> JC XX --> j2EE --> Cluster --> Server 0 --> log, but no log was there.
There were structure changes in the RFC and also code change in my Web
Dynpro code.
I´m working on EP 7.
NWDS version is 7.0.1
Please help me as the production move is pending because of this.

HTTP 500 internal server error while starting abap web dynpro application

Hi there,
i have some problems concerning my web dynpro abap configurations in the system. When i start an application the browser appears and displays the http 500 internal server error. The required icf nodes are activated, as far as i know. the following properties are set:
hostname: aet
port: 8000
The generated url for the web dynpro application looks as follows:
http://aet.ls3001:8000/sap/bc/webdynpro/sap/zwdr_test?sap-language=EN
Maybe anybody of you out there has an idea for that situation.
Thanks for your afford and kind regards,
Albert

Hi Ulli,
the error message says:
UNKNOWN HOST
Description: Unable to locate the server named "aet.ls3001" --- the server does not have a DNS entry. Perhaps there is a misspelling in the server name, or the server no longer exists. Double-check the name and try again.
So the problem is the hostname.
When i replace the hostname with the ip of the server, the following error occures:
COULD NOT CONNECT
Description: Could not connect to the server "10.18.187.9".
But with SAPLogon, its possible to connect on the server by filling in the ip adress.
Kind regards,
Albert

500 Internal Server Error while using BEx Web Application

Hello All,
Kindly help me in resolving below issue which is getting popped up for only few people, when they are clicking some of the MSS links.
500 Internal Server Error

Error Summary
Exception occured while processing the current request;this exception cannot be handled by the application or framework

To facilitate analysis of the problem, keep a copy of this error page Hint: Most Web browsers allow you to select all content, and copy and paste it into an empty document (such as in an email or simple text file)
Root Cause
The initial exception that caused the request to fail was:
Cannot get connection for 60 seconds. Possible reasons: 1) Connection are cached within System Thread (can be any server service or code invoked within SystemThread in the SAP J2EE Engine), 2) The pool size of adapter "SAPFactory" is not enough according to the current load of the system

In case 1) the solution is to check for cached connections using the Connector Service list-conns command, in case 2) to increase the size of the pool and in case 3) to increase the time to wait for connection property. In case of application thread, there is an automatic mechanism which detects unclosed connections and unfinished transactions.
