I'm using ibm rsa 9. In ibm knowledge center I found how to create pluglet:
- Customize your perspective.
- Click Window > Customize Perspective.
- In the Customize Perspective window, click the Shortcuts tab and be sure New is specified in the Submenus list.
- In the Shortcut Categories list, select Pluglets to enable the related shortcuts. Make sure that the Pluglet and Pluglets Project check boxes are checked in the Shortcut list.
- Click the Commands tab. In the Available command groups list, select Pluglets and Modeling.
- Click OK.
- Click File > New > Pluglets Project to start creating the pluglets project.
Unfortunately, I don't see Pluglet in the Shortcut Categories list.
I resolved it with this : http://www-01.ibm.com/support/docview.wss?uid=swg21590669.
To resolve the problem, you have to add new capabilities :
Hope this could help !
