Open from the command prompt

open /Users/mingch/Documents/workspace-freelance/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps

Check the project is there any .class path get copy over. If no class file is copy, try the following solution.

1. From the project explorer, browse the target folder.
