The myeclipse "Generating artifacts" column name is invalid. How can this problem be solved!

The error "Generating artifacts" is thrown when hibernate3.2 is used to map pojo,
Note: I use oracle. If mysql is used, no error occurs.

Open the workspace/. metadata/. log file and find the exception log information thrown by eclipse as follows:

! ENTRY org.eclipse.core.jobs 4 2 2008-04-02 15:22:23. 031
! MESSAGE An internal error occurred :"Generating Artifacts".
! STACK 0
