Redeploy fails after trying to open a socket to an invalid IP address

Question

I'm having a problem with a servlet on the JSE8 application server. In this servlet I write to a socket. Everything is fine if the IP address I write to is valid, however if I try to open a socket to an ip address that doesn't exist I get an exception of course. However, after this if I try to redeploy the servlet I get an error saying the directory can't be deleted and the redeployment fails. Any ideas on what might be causing this issue?

Hey ioannis,
So I would recommend starting from scratch on this one and seeing if we can get things to work.  I would recommend following these steps:
Make sure that you have access to port 80, which is what LabVIEW and the Web Server uses for communication.  This might mean turning off virus checkers or firewalls, as Altenbach suggested.
Restart your computer.  This is to make sure that there isn't anything already accessing this port that is conflicting.
Start LabVIEW once the computer is back up.
Open the VI that you would like to publish.  I might recommend using an Example just to test, but you could use your program.
Select Tools » Web Publishing Tool (WPT).
On the bottom of the WPT window, press the Start Web Server button.
Configure your VI as you would like.  You can probably just use the defaults for now. 
Select Save to Disk and replace the file if necessary.
Hightlight the address that comes up in the Document URL window and press Ctrl+C to copy it.
Open Internet Explorer and past the URL into the address bar on the development computer. 
These steps should be all that is necessary to use the WPT, so please follow them and let me know if they help or not. 
Thanks!
