Webgui error

Dear experts,

I have just installed SAP NetWeaver 7.01 SR1 ABAP Trial Version.

(1) As per the documentation, I tried to access Webgui using following URL but got an error:


Error message reads as following:

Service cannot be reached

What has happened?
URL http://localhost:8000/sap/bc/gui/sap/its/webgui call was terminated because the 
corresponding service is not available.

The termination occurred in system NSP with error code 403 and for the reason Forbidden. 
The selected virtual host was 0 . 

What can I do?
Please select a valid URL. 
If you do not yet have a user ID, contact your system administrator. 


HTTP 403 - Forbidden

Does anybody know the solution?

(2) Another issue - Every time I use a transaction, it starts compling it (because this is first time a transaction is being accessed) and it takes a long time in anything I do. I am sure there must be a program (or report) if i can run that it will do all the compilation. does anybody have any idea of it?
