SCM repository creation

Hi,

I am using clearcase 7.0.1 version with blaze 7.0 but when i goes on for clearcase repository creation it throws an error that ccversion manager class can no be instantiated as there is a class propertyrequestitem is not found ,

I tried to analyse and found that the class needs to be in stpwcm.jar but there is no such class hence giving error.could you throw some light in this regard.

Regards,

Lohit
