I had look on JackRabbit , Alfersco , eXo , and etc. I study the JCR documentation too ,

But I have problem to run one simple example . I can create repository , workspace and node and also

save binary file in node , But for retrieving those things i have problem . for example I want show all content

( Workspaces m nodes , items, properties ) in tree also i wand save one binary file to my hard disk from that repository .

In other word I saved one file ( sample.gif or sample.pdf ) in my A workspace and in node A and in node A i saved that .
