Jersey: "There is no dependence on the method ..."

Question

Can someone explain the meaning of this error?

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 to look around Google, but I could not find the reason.

Thanks in advance!

Answer 1

remove

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

and everything should be fine.

You confuse Jersey by adding a bunch and separate dependencies to the class path. So basically you have two classes that have the same name ("com.sun.jersey.core.util.FeaturesAndProperties" in this case), Jersey runtime expects one, and you provide the second ... or vice versa.

In any case, you should be fine when the jersey-bundle is removed from the class path.

Answer 2

I had a similar problem when working with multi-page downloads. After searching and investigating the bit, I realized that I used different versions of jersey-multipart and mimepull jars, which were not compatible with the jersey kit used in my project.

If you are a non-maven developer, make sure you add the following jars to your classpath:

• jersey-multipart-X.jar
• mimepull-Y.jar

X and Y are version identifiers for jersey-multipart and mimepull jars respectively.

* Please note that X (jersey-multipart version) must be the same as the jersey-bundle jar version.
