This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Is it best practise in maven to have one pom for your entire web project (webcontent + Java Source files) or to have one pom for your web content and then one for your javasource files.
Your Java source files then get packaged to a jar and your WebContent is packaged as a War which depends on the Java Source Files packaged as jar.
I has always seen the servlets and their helper classes appearing in the same projects with the static web content. Thus the classes end up in WEB-INF/classes. In a way this makes more sense because usually the Java sources and the static content are closely related. If the Java classes were packaged in a separate JAR file, one would usually assume that that JAR could be used in multiple projects, which in this instances is not the case.
Unless I'm mistaken, you're considering a scenario where the static content of a webapp is being packaged and deployed separately from the dynamic stuff. JSPs, BTW are not static content - they're compiled into dynamic components, and therefore cannot be effectively deployed in a static content server.
There once was a practical performance reason for separating static and active services in J2EE, but that was long, long ago. Modern-day servers such as Tomcat can serve up CSS and HTML just as efficiently as Apache can, so there's no real reason to complicate matters by creating a separate static content bundle.
If you do choose to separate the 2, however, the "correct" way would be to make each package be a separate Maven project, since the Maven rule is 1 product output per project.
