2 very beginner questions

[benSpec]

Hello,

I've done most of the specifications of the project I'm  working on and now I want to go forward, so :
_ is the way to make a complete document from all the diagrams stands on making a document of each diagram and  then paste them all together ? or is there some way to make it in one shoot ?
For now, I just get a white page but I probably can fixe this ...
_ I've made a test of Model Transformation and generate a javaModel in a file : how can I use this informations ? does it have to be injected in some java tools ?

Thank you for any help
