webui tomcat/tornado issues

So I have now both tornado server and tomcat running and I face two errors. I was hoping you could help out in those:

The tornado webserver starts fine (I dont add papaya.net to my hosts file) but when I try to run http://localhost:8080/ChatService?wsdl I get internal server error (500). The weird thing is this goes away as soon as I switch off my VPN. The error I get with VPN on is :

# Restoring model weights ...
Web service started.
ERROR:tornado.application:Uncaught exception GET /ChatService?wsdl (127.0.0.1)
HTTPServerRequest(protocol='http', host='0.0.0.0:8080', method='GET', uri='/ChatService?wsdl', version='HTTP/1.1', remote_ip='127.0.0.1')
Traceback (most recent call last):

socket.gaierror: [Errno -2] Name or service not known
ERROR:tornado.access:500 GET /ChatService?wsdl (127.0.0.1) 5.01ms

As I run tomcat it spins up the webclient. I enter Hi and the webclient fails with
```
org.apache.jasper.JasperException: Unable to compile class for JSP: 
```

An error occurred at line: 7 in the jsp file: /ajax/getChatReply.jsp ChatClient cannot be resolved to a type 4: response.setContentType("text/html; charset=utf-8"); 5: response.setHeader("Cache-Control", "no-cache"); 6:
7: ChatClient cc = (ChatClient)session.getAttribute("ChatClient"); 8: if (cc == null) { 9: cc = new ChatClient("http://papayachat.net:8080/ChatService", 5); 10: session.setAttribute("ChatClient", cc);

Any idea for both the errors?
