Issue with Webmethods & Clear Case integration


We are integrating Webmethods 7.1 with Clear Case7.
We are experiencing some issues as follows.

While trying create a package,or any component developer throws error “can’t create”.

If we are trying to checkout a flow service also it throws error “Component is not locked”.

We could see some logs like:

java.util.MissingResourceException: Can’t find resource for bundle com.webmethods.vcs.resources.VCSExceptionBundle, key CreateProcess: cleartool lscheckout -directory -me -cview

Has anybody experienced such issue?
Or any guess on the cause of the issue…

Thanks in advance
