webdynpro java session expiration not working in NWDS 7.5

[former_member266708]

Hi All,

We have migrated our application from NWDS 7.0 to 7.5 .

Previously in 7.0 when our application session is getting expired then we were automatically taken by dispatcher to the below screen where an Hyperlink for our application is present.

But now in NWDS 7.5 only blank screen is visible .

***Our Application is custom webdynpro java application.
*** In both cases the session expiration time out is already set in Application properties.

Could you please let us know if we miss something to configure in NWA or somewhere.

Thanks in advance.

Viplove,

Just to help with debugging, normally the logout technique or expiration technique is to force the system to logout and point or redirect the URL to another page. The picture you provided has some https:// address (masked right now) but ultimately it is a logout page.

In one of our SAP products we normally handle this via the ICF (area or SICF SAP transaction). Check if your system needs to be reviewed in this area and determine if the logoff page is still setup correctly. You may compare this to your older system if you still have it up and running.

Check this link just for reference to explain what I stated above (about having a logoff page or redirect HTML link):

Hi Viplove,

Hope you are doing good.
The property DefaultExpirationTime contains the default timeout value for all Web Dynpro applications in seconds. You can perhaps try to increase it as per need. SAP note ##1113811 also provides some info. On 7.1+ server, you should be able to modify this using /nwa or SAP note ##1012065.

Kind Regards,

Dear Viplove,

Please go through on the following SAP Note step by step:

842635 - Session Management for Web Dynpro Applications

However you have 7.5 Java this note is helpful for troubleshooting.
