ServletContainer class not found Exception

Question

I cannot compile my jersey project anymore and I get the following exception:

GRAVE: Servlet /Project-API threw load() exception
java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer

I read on SO that it might be caused by my pom but I cannot figure out how to fix it.

Here is my pom

Here is the minimal set up that just works for Jersey 1. Compare with your version.

Add your repository to pull these jars.

Answer 2

Here's how you solve this sort of problem. You are missing a class, so obviously you need this class in your dependencies. What dependency can you add that contains the missing class?

You can search resources like GrepCode or the Maven Central Repository for your missing class (both those links search for this missing class, by way of example).

Now we know that the missing dependency is com.sun.jersey:jersey-servlet so add this to your dependencies:

<dependency>
  <groupId>com.sun.jersey</groupId>
  <artifactId>jersey-servlet</artifactId>
  <version>1.17.1</version>
</dependency>

By way of a suggestion, I notice that most of your Jersey dependencies are version 1.17.1 but you have one 1.19 in there ... you should probably try to stick to the same version for all of them to avoid any inconsistencies between them.

Also, if these libraries are included in your application server (like Glassfish or Weblogic, etc) then you should have <scope>provided</scope> on all of them. But if you're using something like Tomcat, then forget this (unless you're manually adding them to Tomcat's lib directory).
