Running a multi-module Maven web app in Eclipse

I'm trying to run a multi-module Maven web app in Eclipse (EE Helios SR 1). In NetBeans one have just to click the run button. But here it's probably a little more complicated.

I've added Tomcat 7.0.26 as a server for the war module of the project. When I try running the app, in the Servers part of the window I see Apache Tomcat v.7.0.26 at localhost [Started, Synchronized], but browser doesn't react. Does the system browser need to show the page when the app is running?

I tried to move to localhost:8080 and localhost:8080/welcome.html (the second one should be processed by the app) when the server was started, but I got 404 error both times. I also didn't see the new folder in the apache-tomcat-7.0.26/webapps/. Should Eclipse place the project there when running the application? I'd be really grateful if someone tells me what I'm missing here.

If not specified, tomcat integration with eclipse deploy by default war to a specific folder in .metadata, in my case somethings like: ~/workspace/<my_project_workspace_name>/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/

Every war are then unzipped to a folder. If your maven pom.xml you'll find a

<build>
    <finalName>myapp</finalName>
</build>

Then it'll deployed to tomcat as :

localhost:8080/myapp/welcome.html

I have had a lot of bad experience with running web servers in Eclipse. Most of the time, this was related to unreliable class/resource reloading.

My solution was to add Jetty to my app in a new module (see Embedding Jetty). This basically turns my web app into a Java application, avoiding most of the problems. It also allows me to specify a filter (written in Java) when the app should reload.

This solves all the problems with class reloading (classes and resources are never copied anywhere; they are loaded from Eclipse's bin folders), startup is much faster (we got the startup time from several minutes down to 15s) and reliable.

Maven Projects are different from the ones with Web Application Facets, You cannot directly run a Maven App as a web app because the folder structure is different. In order to run your application directly from eclipse, try to add Web Application nature to your maven project [A complex modification involving modification of .project and .classpath files along with addition of few other files]. I would recommend modifying your pom.xml file accordingly
