What is a best solution for hot deploy to Jetty?

Question

I have a web application which is running on jetty. Continues builds are built on hudson. I would like to make a hot deploy on demand from hudson.

I found cargo plugin which should be able to do so but cargo's web doesn't show any complete example how to do it - for remote jetty server - may be I miss it?

What do you suggest? Do you have any other better solution?

thank you,

Vitek

What version of Jetty are you using? Cargo has remote deployer support for Jetty 6.x+ only (and only for the Maven 2 plugin). — Pascal Thivent, Nov 09 '09 at 06:10

Cargo's documentation shows that it is possible to deploy to jetty via maven 2.

And here is the configuration.

I assume you tried this? What was the problem?

Jetty : can be run as as standalone : just remote copy the war you build . Standalone Jetty instances can be run independent ports .

Yml : eg

<Set name="ThreadPool">
  -->
  <New class="org.mortbay.thread.QueuedThreadPool">
    <Set name="minThreads">10</Set>
    <Set name="maxThreads">50</Set>

For those of you using Windows, if you run into file locking errors, visit:

http://docs.codehaus.org/display/JETTY/Files+locked+on+Windows

Windows locks the files Jetty loads into memory. The above link will show you how to prevent that.

dead link! :( shouldn't answer questions with links like that – Nicholas DiPiazza Jul 17 '18 at 00:47
@NicholasDiPiazza you could just update the link with one from the internet archive. The original post was 6 years before your comment, it is quite common for links to go bad on older posts. – harryovers Dec 18 '18 at 16:15
