After upgrading to Stack 10 I recieve a "500 Internal Server Error "

[Former Member]

Hello. I am running the EP6 SP4 on a Win 2000 environment. We have decided to upgrade to SP10. I have followed the upgrade guide and am still having problems. I have upgraded the WEBAS to SP10 and now am trying to upgrade my portal environment. After getting a successful upgrade message I rebooted the server and I am getting an internal server error(null pointer). I have tried everything to fix but nothing has helped. Here is the exact error message:

Application error occurs during processing the request.

Details: java.lang.NullPointerException

SAP says this problem is UME releated and is fixed in SP11.

Hi Peter

Did you get a resolution to your problem from SAP? I'm getting the same error after upgrading to EP6 SP9 from SP3.

Thanks & regards

Hi Pran,

I had opened an OSS message on Sunday when the error occured and am waiting to hear back from them.

The folder is not there in the server that was upgraded but is there in the production system.

Thanks for the help.

Hello,

I am getting the same 503 error. I am on SP9. We have a very basic config. Deploy service is running successfully. I have no default.trc. The message below, from the server.0.log is the only thing I find but I am still not sure it is the cause.

Any ideas?

Sorry Peter

I am running out of clues , my last check would be to see if this portalapp(com.sap.portal.navigation.AliasService) actually exists in the path

/usr/sap/<sys id>/JC00/j2ee/server0/apps/sap.com/irj/servlet_jsp/irj/root/web-inf/portal/portalapps

You should see a folder com.sap.portal.navigation.AliasService, compare this file system with a successfully running portal (if you have one), or atleast check if the folder exists

Hi,

You can check the path as

D:\usr\sap\<SAP SID>\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\portalapps

And check com.sap.portal.navigation.AliasService

the folder exist or not ?

I am facing the same problem on EP6.0 SP16.

Still the error exist

Hi Pran,

You asked me "Can you check the status of the irj app through the deploy service in Visual Admin". I have opened the visual administrator and found the deploy service on the server but don't know what I am supposed to be looking at beyond that. Anything in particular?

You will have to check for detailed traces to see if there is some parent errors thats causing this (through the LogViewer service in Visual Admin) - I have found the place but do not know what I am supposed to be looking at.

Hi Peter

For deploy service

expand servlet_jsp

and check that staus of the app sap.com/irj ,what is it?

For Log viewer

You need to check the logs in default.trc which is in the path

Cluster

-->usr/sap

-

---

><instance>/JC00

-

---

>j2ee/cluser/server

-

---

>default.trc

Hi Peter

Servlet name 'prt' is mapped to the dispatcher servlet of irj which is the Portal application , for some reason this does not start eventhough it is set as load on startup. Can you check the status of the irj app through the deploy service in Visual Admin . Is it in starting , stop or running mode ? You will have to check for detailed traces to see if there is some parent errors thats causing this (through the LogViewer service in Visual Admin)

Regards

Hi Peter

I assume you get this when you type in the url http://<server>:50000/irj

My guess the some of the app deployments has been unsuccessful. One way to check this is

try logging in with this URL instead

http://localhost:50000/irj/servlet/prt/portal/prtroot/com.sap.portal.navigation.portallauncher.defau.... You should get a login screen. If you get something like Component Name:N/A then that would be the case. Please try

Regards

Pran
