有没有办法将带有“ jar”包装的Maven项目部署到Tomcat7中？

Question

My project generates a Jar as the output package and uses an external War file, available on our Artifactory, as the Web Application to be deployed on Tomcat (currently using version 7). This War file contains all libs and modules required for the application to run.

I have already packaged and ran those projects outside eclipse on a "vanilla" Tomcat installation. In this scenario, the Jar my project generates is loaded on the context.xml file this way:

<Loader className="org.apache.catalina.loader.VirtualWebappLoader" virtualClasspath="/home/igor/workspace/myapp/myapp-2.4.3.jar"/>

Is there a way I can deploy this project on Tomcat using Eclipse and still be able to debug it? Can I use the Jar generated for this purpose or do I have to deploy the workspace project? As for the War file, do (or can) I have to add it as an dependency?

Thanks in advance!

EDIT

We actually provide an Web Framework, which is packaged as a war. Other applications that use that framework are exported as jars and loaded into the framework through the context file as cited above.

Your question is confusing probably because of your custom plugin/classloader and deployment which is sort of orthogonal to debugging.

What I recommend is you keep whatever system you have to build/package/deploy and use JVM remote debugging. That is do not use the Eclipse WTP since you seem to have custom steps for deployment but rather build your code deploy & run a separate Tomcat instance and then run the remote debugger in Eclipse .

You will get some hotcode swapping with this method but not as much as something like JRebel.. (which you could use also) it will certainly be better than constantly redeploying.
