My Tomcat instance is listening to multiple IP addresses, but I want to control which source IP address is used when opening a URLConnection.
How can I specify this?

The Java URLConnection class represents a communication link between the URL and the application. It can be used to read and write data to the specified resource referred by the URL.
connect method is called. When you do this you are initializing a communication link between your Java program and the URL over the network. For example, the following code opens a connection to the site example.com : try { URL myURL = new URL("http://example.com/"); URLConnection myURLConnection = myURL.
URLConnection is the base class. HttpURLConnection is a derived class which you can use when you need the extra API and you are dealing with HTTP or HTTPS only. HttpsURLConnection is a 'more derived' class which you can use when you need the 'more extra' API and you are dealing with HTTPS only.
This should do the trick:
URL url = new URL(yourUrlHere);
Proxy proxy = new Proxy(Proxy.Type.DIRECT,
new InetSocketAddress(
InetAddress.getByAddress(
new byte[]{your, ip, interface, here}), yourTcpPortHere));
URLConnection conn = url.openConnection(proxy);
And you are done. Dont forget to handle exceptions nicely and off course change the values to suit your scenario.
Ah and I omitted the import statements
