My requirement is to integrate a SharePoint(2013) website in WebSphere Portal 8.5 . Right now security is disabled in SharePoint. So the SharePoint application URL is accessible through a web browser without any authentication and the URL is working fine. But when I use the same URL to configure the Web Dock portlet, it seems to be behaving inconsistently. Sometimes, I get the following error message - Error 404: An exception occurred while parsing the URL... But then it starts working correctly after a few page refreshes. Then again after sometime , the same error comes up. This is the first time I'm using the Web Application Bridge so haven't come across similar issues before. Can some one please suggest a solution.
