<p>I'm currently working on a WebSphere 6.1 Web Project.</p>

<p>In my java code, how can i get the current running application port?</p>

The servlet API gives you the local port in HttpServletRequest.
```
```
protected void doGet(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {
    PrintWriter writer = response.getWriter();
    writer.write("" + request.getLocalPort());
    writer.close();
}
```
```
The ports are defined in the node's
serverindex.xml
(e.g. [WAS]/profiles/AppSrv01/config/cells/localhostNode01Cell/nodes/localhostNode01/serverindex.xml).
```
```
<specialEndpoints xmi:id="NamedEndPoint_1214751102556" endPointName="WC_defaulthost">
  <endPoint xmi:id="EndPoint_1214751102556" host="*" port="9080"/>
```
```
I'm not sure if the WAS JMX support exposes this information - you'd have to check the doc.
