Please, help me answer some questions:

As I understand, it comes by default with SAP Netweaver based on Java? So that if I install Netweaver 7.3, Portal will be available right away over the browser, just enteringhttp://server_name:50000 ?. it opens sap Netweaver login page , there in no portal it seems like a sap java stack. so my question is how to install portal?
