BlackBerry XML File Controller

I need a fully working XML Controller written in BlackBerry Java for OS5. Please see the attached files to understand the classes and its relationships. The interface is defined in [login to view URL], it should expose 3 methods: . BigVector getRootNodes() . BigVector getNodesFromBranch(int branch) . IPage getIPage(String pageCode) All data is retrieved from [login to view URL] Please see full description and attached file. ## Deliverables 3 interface methods: > public BigVector getRootNodes(); > public BigVector getNodesFromBranch(int branch); > public IPage getIPage(String pageCode); getRootNodes and getNodesFromBranch should fill a BigVector vector of type IMenuItem All data is retrieved from **[login to view URL]** Data should be retrieved per demand. It should not be cached before requesting a page node or a menu collection. To understand which nodes are root nodes (needed at getRootNodes) see**[login to view URL]** To understand which nodes are branch nodes (needed at getNodesFromBranch) see **[login to view URL]** To understand how an IPage should be retrieved see **[login to view URL]** Any doubt do not hesitate to ask. Thanks!
