How to configure jersey to avoid com.sun.jersey.spi.container.servlet.ServletContainer giving problems?

Question

I have managed to narrow down why I can't compile my project. It's a maven project meant to be an api REST, done on eclipse and the idea is for it to run on tomcat v6.

I had this configuration on the pom.xml:

<!-- Jersey -->
    <dependency>
     <groupId>com.sun.jersey</groupId>
         <artifactId>jersey-server</artifactId>
         <version>1.19</version>
     </dependency>
     <dependency>
         <groupId>com.sun.jersey</groupId>
         <artifactId>jersey-servlet</artifactId>
         <version>1.19</version>
     </dependency>

Which gives me the following error:

java.lang.ClassCastException: com.sun.jersey.spi.container.servlet.ServletContainer cannot be cast to javax.servlet.Servlet And when I've tried removing jersey-servlet, since I've seen people say that they create trouble and I only need jersey-server and so on, I get this:

java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer

I've been messing arround with a lot of configuration, trying to follow different solutions, but I believe the problem lies here. Could anyone tell me how to properly configure this?

Answer 1

Try removing the jersey-server dependency. Use only the jersey-servlet dependency:

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-servlet</artifactId>
    <version>1.19</version>
</dependency>

And ensure the com.sun.jersey dependencies are using the same version. At the time of writing, the most recent version is 1.19.1 .

If it's a new project, forget the old Jersey 1.x and go for Jersey 2.x .
