Can anyone tell me how the work-break-down (WBS) of a project can be created graphically from input values that the Project Manager enters in project management software?
Just show me some steps to build a WBS.
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
Googling for project management tools in java yielded the following: http://java-source.net/open-source/project-management
The above tools are desktop solutions, but if you are looking for a web based solution there is a popular tool called Redmine, which is a project management web application developed in Ruby. You can deploy it on a Tomcat application server using JRuby.
UML is a modeling language you would use to embark on such a task. Many IDE's have UML modeling capabilities for you to make graphical representations of your class hierarchy. Personally I'm quite fond of Intellij IDEA ... there are also some very good Eclipse plugins such as ObjectAid.
EDIT Referencing your update, I recommend taking a look at Enterprise Architect.
If however you are looking a Model Driven tool suite, Enterprise Architect is superb.
