Ubuntu Server 12.10
Tomcat 7
BaseX 7.6

We are using the client module to make the following call: client:connect($app:feedback-server-host, 1984, $session-user, $session-password). Port 1984 successfully connects within a client/server application; however, when we deploy as a web application to Tomcat, either BaseX Server is not starting up or port 1984 is not available. We added <param-name>org.basex.debug</param-name> to Tomcat's web.xml. The output of …/tomcat7/logs/catalina.out follows:

I ran netstat -an | grep "LISTEN ". Port 1984 was not listed. Thinking that 1984 was closed, I ran iptables -A INPUT -p tcp -d 0/0 -s 0/0 --dport 1984 -j ACCEPT. However after running netstat -lnp | grep 1984 -- still nothing. 

The file .basex is at the root of our webapp and looks like this:

...
# Client/Server Architecture
HOST = ouripaddress
PORT = 1984
SERVERPORT = 1984
EVENTPORT = 1985
USER = user 
PASSWORD = userpassword 
SERVERHOST = ouripaddress
PROXYHOST = 
PROXYPORT = 80
NONPROXYHOSTS = 
TIMEOUT = 30
KEEPALIVE = 600
PARALLEL = 8
LOG = true
LOGMSGMAXLEN = 1000
...

Any help as to why we are not able to connect would be much appreciated!

could you additionally tell us what error message is attached to the error code?

As your code seems to work on your Mac, I indeed assume it has to do
with the servlet configuration. You could try to add the following
snippet to the web.xml configuration file:

  <context-param>
    <param-name>org.basex.debug</param-name>
    <param-value>true</param-value>
  </context-param>

This way, some additional debugging information such as Java stack
traces will be output to STDERR, which you could send us as well (this
information may e. g. end up on command line or in logs/catalina.out,
depending on your Tomcat configuration).

Hope this helps?
Christian
