Did you choose to install all 3 options during the installation? Namely:
- IBM Worklight Studio
- IBM jQuery Mobile Tools
- IBM Dojo Mobile tools
In any case, there is another way to add the Worklight options (it will add it to both the File >> New... menu and the right-click context menu >> New...):
- Window >> Customize Perspective... >> Shortcuts
- In the Shortcuts Categories section on the left side scroll all the way to the bottom and tick the "Worklight" checkbox
- Press OK
Even w/out doing the above, you always have the Worklight icon in the top toolbar which hold the same functionality.
Personally I don't like using the File menu for that. I find myself using either the Worklight icon in the top toolbar or the right-click context menu (less restrictive as you can get to it from anywhere you right-click while in Eclipse).
