WDPortalNavigation.navigateAbsolute is not working correctly.

[anandprakash_rai2]

Hi All,

I have a  page in portal.When the user clicks on this page then a web dynpro java application iview will be called.

In this an wd java application runs. It checks for some data base entry and if that entry exist then we navigate to a new page in the portal.I have used

WDPortalNavigation.navigateAbsolute api in my wd java component.

The issue is

I am getting an error while using this api  WDPortalNavigation.navigateAbsolute.

The code which I have written is

WDPortalNavigation.navigateAbsolute("my pcd  address",WDPortalNavigationMode.SHOW_INPLACE,WDPortalNavigationHistoryMode.NO_HISTORY,"");

The error is

NavigationNode.addExtConnectorKeytoEnv: Exception

[EXCEPTION]

java.lang.NullPointerException: while trying to invoke the method java.util.Hashtable.remove(java.lang.Object) of a null object loaded from local variable 'env'

What portal version? Is the navigation triggered? See if SAP KBA 1917848 is relevant.

[anandprakash_rai2 · Accepted solution]

the portal version is 7.3. Yest the navigation is getting triggered but I am getting an above error in the log.

[anandprakash_rai2 · Accepted solution]

Hi Samuli,

Thanks for your reply.I asked the SAP to provide us the patch. Will let you know once resolved.

Thanks

Hi Samuli,

The above mentioned problem is resolved by referring to the KBA. I have awarded points to you.

But I am facing one more error in my log.

Once the user clicks on the web dynpro iview the application on portal runs fine but in the log I am getting an error message for that user. It just shows the system.err and I dont get any details in the log.

PFA the error log

WD java application name is – dc-wd-stc-bi-disclaimer.

This error we get only when user clicks on the web dynpro iview referring to this application in portal.

I don't know what component that is. Use System Components in NWA to locate the software component and look for SAP notes/patches for it.
