[INFO] Started Jetty Server

I am using Jersey 1.11 + Jetty 7.6.1.v20120215.
These are my dependencies:

                <dependency>
                    <groupId>com.sun.jersey</groupId>
                    <artifactId>jersey-bundle</artifactId>
                    <version>1.11</version>
                </dependency>
                <dependency>
                    <groupId>com.sun.jersey</groupId>
                    <artifactId>jersey-client</artifactId>
                    <version>1.11</version>
                </dependency>
                <dependency>
                    <groupId>com.sun.jersey</groupId>
                    <artifactId>jersey-servlet</artifactId>
                    <version>1.11</version>
                </dependency>
                <dependency>
                   <groupId>com.sun.jersey.contribs</groupId>
                   <artifactId>jersey-multipart</artifactId>
                   <version>1.11</version>
                </dependency>

I tried looking around Google, but I couldn’t seem to find the cause.

Thanks in advance!

Answer 1

remove

   <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-bundle</artifactId>
        <version>1.11</version>
   </dependency>

and you should be fine.

You are confusing Jersey by adding bundle and separate dependencies to the classpath. So basically you have two classes which have same name (“com.sun.jersey.core.util.FeaturesAndProperties” in this case), Jersey runtime expects one and you are providing second one.. or vice versa.

Anyway, you should be fine when jersey-bundle is removed from classpath.
