Hi all, My problem is finally resolved! There are couple feedbacks I like to give back to Maven users/developers:
1. The archetype:create plugin generate webapp that has web descriptor(web.xml) set to version 2.3!!! big nono if you want EL stuff to work. Would be nice to upgrade to latest, or at least 2.4 2. When running a webapp in a IDE(m2eclipse in my case) environment, I can't add servlet and jsp api in the top level dependencies, as it gets pulled into the classpath by IDE, and therefore conflicting with the internal Web container's version. (Setting it to "provided" scope didn't work either) The solution I have is to create a profile dependencies in pom, and even set to activeByDefault will work! And here are steps I used to start a fully working webapp with latest Maven2+Eclipse europa(j2EE)+Tomcat6+m2eclipse plugin. 1. $ mvn archetype:create -DgroupId=cnx -DartifactId=mywebapp -DarchetypeArtifactId=maven-archetype-webapp 2. cd mywebapp 3. mvn eclipse:m2clipse -Dwtpversion=1.5 4. Replace pom.xml with: http://snipplr.com/view/3774/maven2-pomxml-for-a-webapp-that-works-in-eclipse-europam2eclipse/ 5. Replace src/main/webapp/WEB-INF/web.xml with: http://snipplr.com/view/3775/minimal-web-descriptor-version-25-webxml/ 6. Add any EL or JSTL to src/main/webapp/index.jsp for testing. Eg: ${header} 7. Open Eclipse and Import Existing project mywebapp 8. In eclipse, right click project and go to J2EE Module Dependencies, check M2REPOS library. 9. Create a Server runtime with Tomcat6, Add mywebapp module, and Starts it. 10. Hit http://localhost:8080/mywebapp and test away Thanks, -Z On 9/18/07, Jim Sellers <[EMAIL PROTECTED]> wrote: > Z: when you say that it's not working, do you mean on the .classpath file > for eclipse? > > Does this seem like the same problem as you are having: > http://jira.codehaus.org/browse/MECLIPSE-79#action_99459 > > Jim > > > On 9/18/07, Wayne Fay <[EMAIL PROTECTED]> wrote: > > > > Google for "maven exclusion". > > > > Wayne > > > > On 9/18/07, thebugslayer <[EMAIL PROTECTED]> wrote: > > > Max, > > > How would I exclude the javax.servlet:jsp-api one?
