Eclipse(4.2) maven(3.0.4--m2e) integrate with tomcat 7 (win7)

1.Install maven plugin(The picture following showed for you means you maven plugin "Maven Integration for Eclipse" was already installed)

 

2. Add tomcat 7 server to eclipse IDE(On picture you can find tomcat version information.)

 

 Change publishing option and Server Locations option.

 3. Create a maven project, and config it  as a jsf project.

</project> 

project struture maybe like this:

Config "Run Configurations" and run it(Project menu --> Run as --> Maven build)
 
Config source output directory to "target/Test1/WEB-INF/classes"(If can't find the folder, refresh project)
 
Config tomcat 7 to deploy the project, open server.xml file in Servers project(When you added a server this project is existed)
 
Add this line to deploy project(nested in Host XML element):
 <Context docBase="D:\projects\Test1\target\Test1" path="/Test" reloadable="false"></Context>\
"D:\projects\Test1" is project base path, "target\Test1" will be generated after maven build project.

4. Debugging
Make a breakpoint in your java code(In my demo project, I maked one in jsf managed bean, and triggle it by submitting a jsf action.)

 

Start tomcat server in debug mode.

 

Open your browser and open url "http://localhost:8080/Test/index.jsf", then click the button and submit an action:

The IDE find the breakpoint but not found the source code, then click "edit source lookup path" button to add project source path:

 

 

 

 

 

OK, then go to breakpoint

 

If you delete a line of method "say", you don't need redepoly project util it taking effect.

That's it.
