retrieving web item properties

Hi All,

I'm trying to use BW 3.5 JavaScript functions like SAP_BW_Get_url and SAPBWGetItemProp(itemName) on BI 7.0 environment in my custom JavaScript functions(using new JavaScript web item) but nothing seems to work, Do we have new set of JavaScript functions to perform these similar things in the new 04s environment?

Any help is appreciated.
