what are all the latest technologies in netweaver

Netweaver is a suite of products

SAP NetWeaver is a set of capabilities that are provided by many different SAP products constructed to work with each other to make applications work together, build new applications on top of existing applications, and lower the total cost of owning applications.

i guess SAP Netweaver is having around 8 components like SAP Portal,Process Integration,BW,RFID,Application Server are a few components.

In addition to this we have 3 development tool,among them are NWDS(Netweaver Developer Studio),VC(Visual Composer).

The various components of SAP NetWeaver work as a part of orchestra. Each is a powerful instrument that can make many different kinds of IT music, but each also has one thing that it does particularly well. Each uniquely talented component has the most value when playing well with others to solve a problem

Now abt your question--- latest technology in netweaver.if you are talking abt Languages then we can use Java and ABAP to develop an application in NW.

Hope this will be helpful to you.
