Dynamic Web Project option missi

I had the same problem and did this:

1. Click "Help" > "Install new software"
2. In "Work with", paste: http://download.eclipse.org/releases/kepler
3. In "Web, XML, Java EE and OSGi Enterprise Development", check:
   1. Eclipse Java EE Developer Tools
   2. Eclipse Java Web Developer Tools
   3. Eclipse Web Developer Tools
   4. Eclipse XML Editors and Tools

Finally, click "Next" to install the new software and "Dynamic Web Project" will be available.
