The three minor hurdles to configuring Jetty 7 and Maven are making sure port 80 is not already taken, getting the right connector implementation configured, and running Maven as sudo so that Jetty has permission to run on Port 80. In OS X, you can see if anything is already running on port 80 by running the following command from Terminal:

If you're on OS X and see something running on Port 80 yet you didn't install a webserver, chances are it's Sharing. Go to System Preferences > Sharing and disable it. Otherwise, figure out what process is running on port 80 and make it go away.

Now to configure the Jetty Maven plug-in, here is what my configuration looks like which you should replicate in your pom.xml under the plugins section (and adjust to your particular directory structure and desired context):

One of the difficulties I encountered was getting the connector working correctly. Since Maven has moved to be an Eclipse project, the package structure for the connector has changed and thus the reason most of the existing documentation on getting custom connectors to work did not work for me.

The last remaining hurdle to overcome is that running a standard “mvn jetty:run” doesn't work on OS X (and likely Linux as well). You'll see the error message “Embedded error: Permission denied”. If you run Maven with error stacktraces enabled, you'll see an exception that looks like this:

This is because you need elevated permissions to run applications on lower ports on *nix based systems. Simply run it as sudo, “sudo mvn jetty:run” and you'll be good to go.

Not a terribly tough problem to overcome on your own, but I thought I'd try and try to save someone some time if they run across the same issues.

I found a question/thread on StackOverflow where someone else had already pondered the same thing and got a long list of possible answers to compare to each other, including using Apache Commons and the Google Collections Library. After testing all of them, the fastest way ended-up being implementing a "MutableInt" class and using it as the value data type in the map:

Pretty interesting stuff! Note that the above code snippet is not very cleanly formatted, but you'll get the idea.

Microsoft Remote Desktop for OS X

Alternatively, you can also try downloading CoRD, an open source Remote Desktop Client and installing it. It seemed to have trouble connecting to my Windows XP workstation for whatever reason, but that doesn't mean it won't work for you of course.

CoRD

CoRD is a Mac OS X remote desktop client for Microsoft Windows computers using the RDP protocol. It's easy to use, fast, and free for anyone to use or modify.

Luckily this is easy to install, just not terribly intuitive or easy to find as it's not a package known as dig:

That's pretty much it-- you should now be able to use dig!

A couple of years ago while setting-up a new J2EE server cluster using the Implementing Multitier Hardware Load Balancing with ColdFusion MX for J2EE or JRun article, I needed to setup a proxy filter for ColdFusion requests. Given that the application I was setting up used a context root of /, the proxy rule listed in that article would not work. Instead, thanks to my former co-worker Rod, I now have a regular expression which will redirect all basic requests for ColdFusion:

This regexp works for the following combinations:

And the following requests are not proxied:

Obviously these are just basic test cases, but it should leave all CSS, image, JavaScript, etc. type requests to the webserver, and pass on everything else to the app servers. You would also need to change it to include direct requests for .cfc files if you're doing anything like Flash Remoting, Web Services, etc directly to CFC's.

Basically in any Unix type derivative such as Linux such (Ubuntu, RedHat, SuSe, etc.), as well as Mac OS X, all that you need to type this at the command line:

I remember there being a couple of commands in Windows which you could do this with, but it's been so long since I've used Windows on a regular basis I honestly don't remember how to do it. I do know you can use TCPView to accomplish the same thing, however.

Easy solution:

In the address bar of Firefox, type:

Search or scroll down to the section called "network.http.sendRefererHeader" and change this value to 1.

For some reason, this was set to 2 on my machine.

Annoying solution:

Something is probably corrupt in your Firefox profile. Given that you're the type of person who shops at newegg, AND uses firefox, you can probably figure out how to create a new profile on your own.

Anyhow, give those a try and see if they work. It's nice to be able to shop on Newegg again with Firefox!

... you've came to the right place.

There are many ways to setup your package structure under Maven2 to build EAR's, but essentially what I do is create a root level project which packages a given application into an EAR, and nothing more. Once you have the maven-ear-plugin setup for the most part, all that you need to do is to tell the Maven EAR Plugin to treat the various Axis2 pieces of shit packages like JAR's:

This is just one of many gotcha's I learned about while working on an aforementioned project. In fact it's really pretty hard to find any comprehensive documentation on getting EJB3, Spring, and Hibernate working together on JBoss with a typical Java web application, especially while using Maven. I have a sample project I used to work through some of the integration issues with this, and will hopefully be able to wrap it up and add it to Google Code in the next few weeks to provide an example of getting all of these technologies to play together.

Though Java 6 didn't provide quite as much new syntactic sugar as Java 5, the performance increases in Java 6 are pretty dramatic. I highly recommend giving Java 6 a look if you're doing any development which runs on the JVM if you haven't already switched.

Keep in mind that this is mostly a developers port as it's not yet integrated into Cocoa, the MacOS X native GUI. Desktop applications will run under X11, but this is the next hurdle to tackle (though it seems to be a pretty big one).
