New Codesytel guidlines and some questions

Hi all, at the moment I am working on xml-rpc in xwiki, I am adding documentation and fix the coding style. But I run in some trouble: 1) I have an interface "ConfluenceRpcInterface", which is documentet quite well. Now in "ConfluenceRpcHandler", which implements the "ConfluenceRpcInterface" I need to add javadoc to each method. The question now: Shall I copy and paste the javadoc from the interface, is it okay to add something like /* * (non-Javadoc) * @see com.xpn.xwiki.xmlrpc.ConfluenceRpcInterface#login(java.lang.String, java.lang.String) */ or should I not document the interface and add the documentation to the implemantion of the interface? 2) ArrayList is not allowed. What should I use instead? Thanks, austriancoder
