Maven WebApp with Intellij - procedure

Question

What is the procedure to make a Java EE WebApp with Maven and Intellij?

This is what I do:

• File / New / Project
• Project Type : Maven
• Create From archetype : maven-archetype-webapp

But when I create a servlet IntelliJ shows a symbol on the servlet:

This symbol is "Java class located out of the source root. Refer to the section Configuring Content Roots for details"

If I launch the project I get an error.

If I mark the "resources" directory as "Sources Root", the project works.

But if I reload Maven (right click / maven / reimport) the resources directory lost the "Source Root" structure.

I think something is wrong in my procedure.

Answer 1

Create a new folder under main called java. Then right-click it and select Mark Directory As -> Sources Root. Use this directory for all your java code and everything should work!

Answer 2

Thank you to Chrkv !

1). Create a new folder under main called java. Then right-click it and select Mark Directory As -> Sources Root

2). In Project Structure / Modules / Web enable the checkbox for makes java "Sources Root"

Now i can use right click on java / New / Servlet.

What is the "resources" directory ? (if i cant create servlet here)

Is this the right precedure ?

I'd also encountered the same issue and found a solution by replacing the dependency:

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>servlet-api</artifactId>
  <version>2.5</version>
  <scope>provided</scope>
</dependency>

by following dependency

<dependency>
      <groupId>javax</groupId>
      <artifactId>javaee-api</artifactId>
      <version>6.0</version>
      <scope>provided</scope>
  </dependency>

after adding this and making the java the source root directory as mentioned in above answer, the intellij idea provided the option for creating filters along with web services. I followed the steps from the link : http://www.tugay.biz/2013/10/hello-world-web-application-with-maven.html
