Where should I add Java files in web (WAR) project in Maven?

Question

Where should I have my Java source folder in the Maven web application architecture which results in a WAR?

Suggestions needed.

Answer 1

The basic structure that is standard for Maven project is the following.

src/main/java        Application/Library sources
src/main/resources    Application/Library resource
src/main/filters      Resource filter files
src/main/assembly    Assembly descriptors
src/main/config    Configuration files
src/main/webapp    Web application sources
src/test/java        Test sources
src/test/resources  Test resources
src/test/filters      Test resource filter files
src/site              Site

Following the Maven recommendations and normal behavior makes it easier for other people familiar with Maven to easy recognize and understand the structure.

Answer 2

Maven web applications typically do not include java source code. The maven approach is to create a maven project for the "logic" of your web application (this will build into a jar) and create a second maven project for the webapp portion of your web application (this will build into a war). Then in the webapp portion, you introduce a dependency on the "logic" portion.

The end result is that when you build / test your logic jar (which contains servlets, etc), you will deploy that to your local repository and then build your war (which contains jsp pages, web.xml configs, etc).

Answer 3

Unless you explicitly specify it differently in your pom.xml (productive) Java source files in a Maven project go to src/main/java.

Answer 4

Java files always go in src/main/java and its advised to keep it that way.
