Error while rebuilding webdynpro application

Hi,

When i am building my application i am getting two errors.

1 . This compilation unit indirectly references the missing type com.sap.tc.logging.Location (typically

*some required class file is referencing a type outside the classpath) *

2 . The project was not built since its classpath is incomplete. Cannot find the class file for

*com.sap.tc.logging.Location. Fix the classpath then try rebuilding this project *

Please suggest how to resolve these issues. I have checked the classpath and added the required jar

files also.

Thanks a lot.
