Question

I’m a novice in using maven and idea. I passed throught all intuitive steps to run web project but have got 404 page (this application works well if I use as a simple web project in Idea). The pom file is below:

Could you please tell me the my fault or suggest a article where I can find the explanation of this?

Answer 1

As others mentioned, yo need a war packaging. To be sure, start your project with a maven archetype, see http://maven.apache.org/guides/mini/guide-webapp.html

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-webapp -DarchetypeArtifactId=maven-archetype-webapp

Make sure you can build a war:

mvn clean install

Now import your project in IDEA: File, New Project, Import Project from external Model, Maven, select your pom.xml.
