Not all of them are required (I think), but after installing the components listed below I got the “Dynamic Web Project” template added to my Eclipse (Indigo). The list is:
- Eclipse Java EE Developer Tools
- Eclipse Java Web Developer Tools
- Eclipse Web Developer Tools
- Eclipse XML Editors and Tools
You can install those packages by clicking on “Help” > “Install New Software”, selecting the repository that corresponds to your Eclipse build (i.e http://download.eclipse.org/releases/indigo for Indigo). The packages are grouped under “Web, XML, Java EE and OSGi Enterprise Development”.
