Simple Question+ JAR

[vadey]

I want to add jar file in project (maybe Class model ) and it show me diagram of class ?  

Menu
 Project
    Source Code Engeneering
       nothing active

How can I do it ?

Right click target package: Code engineering/Import binary/Select Jar

The items in the Source Code Engineering menu all require a model to be open and either a class diagram open or the current package in the Project Browser to not be a root node.

From there Thomas is correct, the import binary item is what you need.
