Easy way to run Tomcat on port 80 (not as root)
I am sure that I am not the only Java developer to suffer a little while configuring Apache and Tomcat. The Apache foundation has a project common daemon that supports starting a Java process as root, binding sockets lower than 1024, and then switching to a non-root account to actually run Tomcat. This was easy to set up under Linux, more of a hassle under OS X.
This is especially cool/useful for me because the web applications that I develop have little or no static content, so running Tomcat through Apache never did make much sense for my applications. Check it out!
