I have a webapp that needs to be deployed to Websphere 8.5, (it works fine in tomcat 7). This app calls the REST webservice of another app, and uses HttpClient for that. When I start the app I get the following error:

I've found this question but it wasn't really helpfull. Can anybody help me with this?
Httpclient libraries conflict with WebSphere provided. Please try to create isolated shared library via Environment > Shared libraries, put the http client jars there and map that library to the application. See more details in this post WebSphere 8.5 and Apache HTTP Client
