Re: [las_users] LAS Server Error: javax.servlet.ServletException,still doesn't work

[Eleni Hatzikosti <ehatz@xxxxxxxxxxx>]

Jon,

   Hi. I removed my las installation, and set it up from the beginning, 
setting the configure, and configure.pl as root owner and root group and 
made the configuration.
When I was asked to give my web server address without including the port in 
non-standard (I didn't gave it - before I was writing 8080), and after all 
it worked perfectly. Actually I didn't understood what was the problem 
exactly but after this operations it worked.
