I’m new to Java development, here is the question:
I have generated the web application
mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=webapp -DarchetypeArtifactId=maven-archetype-webapp
, then i have added java.com.mycompany.app folder with the simple App.java file.
By the command mvn package tomcat:deploy in my localhost:8080/manager i can see my web app, but how can I add my jar file in it?

    • When adding a class in src/main/java, Maven compiles it and ensures it gets copied into your WEB-INF/classes directory — so no need to do anything. So your class com.mycompany.app.App should have been picked up by Maven, compiled and copied into WEB-INF/classes (you should be able to verify this in the target/ folder).
    • If you want to add another jar file into your war file, you need to add this jar as a Maven dependency in your pom.xml file.
