There could be many causes for a 404 error. Use version control to see exactly what was changed and revert it if necessary; look into the log file and see what error message you've got. If you still can't fix it, come to my office hours on Monday.

There should be more before this.

here is my logFile

It's a log file from three days ago.  The warning doesn't seem to have anything to do with the current 404 error, which seems to indicate that the project was not deployed (thus it didn't generate any error message in the application log).

Try the following:

• Stop the server.
• In the Servers view, delete csns under the server.
• In the menu, select Project -> Clean... -> Clean all projects
• Delete csns-*.xml and web.xml under web/WEB-INF
• Refresh the project
• Run the project again

If this does not work, you need to bring your laptop to my office hours.

Hi ,

I have 404 error after adding new model classes, hbm mapping files into the project and change hbm config file and run on the server again. I am not sure it is same problem as Sanaz_6101 but I followed the above instructions but it does not work. I have attached the log file. for mapping error, although i can successfully generate csns.ddl, there is one exception for mapping issue. Any idea? Thanks.
