Exception accessing portal over web dispatcher

[former_member185029]

Hello experts,

We are facing issue while accessing portal over web dispatcher on IE (7 & 8).

We get following exception when we try to load any WebDynpro IView (both standard and custom)

com.sap.tc.webdynpro.services.sal.deployment.core.ClassLoaderException: Classloader of 'sap.com/pb' is null, even though application is started.

We are able to execute the application in following ways though

1. Accessing the portal directly bypassing webdispatcher

2. Using Mozilla Firefox browser to access the webdispatcher URL.

Please guide what is missing from the configuration perspective to make it work on IE.

Appreciate the responses.

Thanks

Hi,

Do you get an error message in the dev_webdisp when this occurs?

Does this error occur exactly at the time that you get your error when accessing the portal? If so, increase the trace level of the WD and check once more..

Kind regards,
