Call method without parm

[<SRamanujan@xxxxxxxxxxxxxxxxxx>]

I am new to java calls from rpgle.  I was trying to validate a URL and get the 
server and port from the url using getHost and getPort methods.  I could get up 
to URL constructor, but when I call the getHost I seem to have problems.  I 
keep getting getHost call error or class error.  I have pasted the code I used. 
 I also wanted to know how to read a string returned I have used AS/400 alpha 
numeric in PR for return. But am not sure this will work.

TIA,
Sudha
