Pinned topic Websphere portal Exceptions after clearCache

‏2019-08-13T10:42:26Z | portal8.5

Something weird happened on my portal server ( fortunately a developper one ).

Just after running the commands to clear the cache ( clearCache and osgiCfgInit ), a restart of a server shows a bunch of exception related to the javax.portler.* package.


ClassNot found exception on PortletRequest, PortletSession ..... I was able to get rid of some of these exception by adding to the "app" directory the right "jar" files ... But this is not enough. Even the "Admin console" is showing the exception. Below is an example.


I have install a new profile ( using the same WAS installation ) of WPS ( vanilla ) on the same machine and got the same error. This is the reason why i am assuming that the problem is not centered on WPS but WAS .. Plugins ? WebContainer ?

Any idea ?




Thanks a lot.
