You can get Fuse IDE to build your project and install your jar / bundle / war to the hot deploy directory of your application container (Tomcat, Jetty, ServiceMix, Karaf).

Just right click on the project and select Deploy To -> ....

First time you try you need to setup a new Container configuration in the preferences. You can set up a few different ones if you prefer (so you could setup a few versions of Tomcat or Tomcat and Jetty and Karaf).
