Hi all, Today I made the relevant code changes in AnnotationBinder.java, EJB3Column.java and table.ftl. Its worked like dream.Just I couldn't believe myself. Please take diff from the existing file and let me know your comments. Sorry I could not send the diff. Changes made: Classs Name: EJB3Column.java Methods: initMappingColumn,buildColumnFromAnnotation (with additional parameter String columncomment). Class Name: AnnotationBinder.java Methods: processElementAnnotations Regards, Prasanna On 1/29/08, Prasanna Kothandaraman <prkothan(a)gmail.com&gt; wrote: > > Hi all, > > Got the breakthru in problem I narrated in my earlier mail.
