Eclipse ClearCase plugin and CCRC

I am new to ClearCase and CCRC in particular. Can someone help me, please? I have a CCRC installed and I have a view. How can convert this view to a eclipse project and use the ClearCase plugin functionality? I have tried to associate a project, but always seems to get:

An internal error occurred during: "Refreshing ClearCase Resource States". java.lang.NullPointerException

Environment details:

• Eclipse Platform Version: 4.3.2

• Eclipse ClearCase Integration Version: 2.2.35.201406121752

• Rational ClearCase Remote Client Version: 7.1.1

Thanks!

The two are not related:

• once you have added an existing web view to your ClearCase navigator, you have a web view copy area path which contains the files locally.
• in Eclipse, you can define a new project, adding that project in the same folder as the web view local path: the goal is to define the .project and .classpath where the web view and the sources are.

If the Eclipse project is where the ClearCase view is, then the ClearCase options (checkouts, version tree, merge, ...) will be available.

Make sure to not use the ClearCase Eclipse plugin from sourceforge though: it works for classic ClearCase, not for CCRC.
