class vs component diagram

[Kazimierz Trzonek]

which classes from the class diagram i dont have to put in component diagram?

do i put interfaces or their implementations in componenet diagram?

which classes that arent on class diagram do i put on component diagram?

what are objects that i put into component diagram? are they classes from class diagram?

is eg security (implemented declarativly in web.xml) a component?

does component ~ class or component ~ package/functionality

which relationship line should connect service with dao on class diagram?

is there any sample solution of sample assignment? or any old assigment from sun?

So, I think you might want to start off by defining what a component diagram is. Do a google search and find some sample component diagrams, and find a good definition. Then share with us on this thread what you found out.

From the questions you're asking, it seems that you're really struggling with what a component diagram is. Components and classes are very different concepts.

when do we use assembly line, and when normal arrows?

when one component displays an interface, and other uses it - than it's assembly?

but whan use line whith arrow?

shouldn't on below picture be used assebly connections? (picture from http://www.visual-paradigm.com/VPGallery/diagrams/Component.html):



on the picture from wiki assebly is used in internal dependencies of component, and arrows connect to external ports.

are ports equal to interfaces? name port is used in external context and interface in internal?

Read the relevant section of the UML 2.x specification. It makes it quite clear what the various elements are for, the constraints that exist upon them, and the associations and attributes that characterise them
