What is a best solution for hot deploy to Jetty?

Question

Hi,

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

Answer 1

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?

Answer 2

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