Can't invoke a service in Java extension

Hi,I'm going to write an expansion package to get some data, but in ThingWorx I made the following mistake:

[context: com.thingworx.webservices.context.HttpExecutionContext@4f87ac83][message: Unable to Invoke Service ReceiverStringMessage on TestHttpThing : org.jboss.netty.handler.codec.http.HttpRequest.setHeader(Ljava/lang/String;Ljava/lang/Object;)V],

ErrorCode(85ca1119-3609-4f9e-b926-c03164007877), Cause(org.jboss.netty.handler.codec.http.HttpRequest.setHeader(Ljava/lang/String;Ljava/lang/Object;)V), Reason(A Java method definition was not found at runtime.), Possible Resolutions([1]=Verify that you are compiling against and running against the same Jar and/or class definition versions., [2]=Verify that you have including the correct version of the Jar file in your Extension manifest file as a Jar Resource.)
