I am a litter confusing. If I deploy by myself,that to say I copy the "F:\mavenTest\MT-Parent\MT-web\targetMT-web.war" to the tomcat install directory: C:\tomcat6.0\webapp, what does the eclipse debugger do ? Without the IDE debugger I also can visit my page by " http://localhost:9000/MT-web/helloServet"
Now I add some breakpoints in a servlet under the MT-server(a dependency of MT-web) and I want it hangs up in the breakpoint when I request the servelt such as "http://localhost:9000/MT-web/helloServet"
