500 Internal Server Error in Webdynpro Java

[Former Member]

Dear Team,

We are using EhP 5 including some web dynepro java applications (claim services, income tax declaration and leave encashment). While accessing such application we are getting 500 internal server error without any details log of error.

Hereby, we have attached screen shot of error for ready reference (Complete screen shot of error).

No details error log availabale in NWA or ST22.

Your effort for the same is highly appreaciated.

Thanks & Best Regards,

Dear All,

Thanks for the solution.

The issue is resolved at some level.

As we have 2 EP application server. (Let say A and B)

Cause: If user is accessing application, and it instance connected to A which it is working. But after some time same user is accessing application, instance connected to B. It is not working.

As Port is maintained for A server however, not maintained for B. Hence, when it is connected to A, it will work but when it is connected to B. It will not work.

Here is the solution:

1. Checked issue log in NetWeaver Administrator (in Portal Index page).

2. Checked Issue message: Message sort of Service file at server level

3. Checked service file in etc system folder at server level

4. In that file, port is maintained in only for one application server.

5. Maintain for second application server.

Thus, Issue resolved.

Thanks to our senior basis consultant.

Thanks,

Ketul
