Hi Kingofhawks, If you want to manage some directory and file it's certainly could me more easy to use directly the OS capability of networking directory because managing the change of your tree could be more complexe that install a samba server or something like this. If you use tree, this tree must just reflet the directory structure, not the data on the files. The file must transfert and update on demand with a byte[] flow. Fo your directory structure you have to make an ejb that compare the server tree and the client tree and apply the difference (delete, rename...). For the file you ejb just need to read/write file and convert this to byte. I hope this help.
