[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>

                   <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!

回答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.

I had experienced similar issue while dealing with multipart uploads. After bit searching and investigation, I figured out that I was using different version of jersey-multipart and mimepull jars which were not compatible with the jersey bundle used in my project.

If you are a non-maven developer, make sure that you have added following jars in your classpath:
