A few useful tips for your web service configuration:

1. How to change the port of tomcat server?
If you are using tomcat as a stand alone web server, the default port is 8080 (full url is http://YOUR_HOST_NAME:8080). To change the port number, go to $CATALINA_HOME/conf/server.xml, find this part:

<!-- Define a non-SSL Coyote HTTP/1.1 Connector on port 8080 -->
<Connector acceptCount="100" connectionTimeout="20000" debug="0" 
disableUploadTimeout="true" enableLookups="false" maxSpareThreads="75" 
maxThreads="150" minSpareThreads="25" port="8080" redirectPort="8443"/>

Change the port to your favorate number.

2. How to monitor the soap message?

As a convenient note, add this part to the corresponding <service> element 
 (in $AXIS_HOME/WEB-INF/server-config.wsdd) of your web service:

   <requestFlow>
    <handler type="soapmonitor" />
  </requestFlow>
  <responseFlow>
    <handler type="soapmonitor" />
  </responseFlow>

3. How to adjust the memory setting of tomcat?
Set CATALINA_OPTS in catalina.bat or catalina.sh. For example, in catalina.sh, add
export CATALINA_OPTS="-Xms64m -Xmx256m"
