Jersey restful service communication(IncompatibleClassChangeError)

我在JDK 1.6 http服务器上创建了一个基于jersey 1.12的宁静服务外观。当我在eclipse中启动我的应用程序时,一切正常。我可以毫无困难地与外观进行通信,但是当我使用启动脚本通过控制台启动应用程序时,我在访问服务时遇到了IncompatibleClassChangeError。

我能够缩小问题的范围。问题在于发送响应。因为我可以正常地与服务通信(请求被处理)但我没有得到回复。你对此有什么线索吗?

启动脚本

#!/usr/bin/env bash
libpath=
for i in $(ls lib/*|grep ".jar"); do 
    libpath=$( echo "$i:$libpath"); 
done
java -cp "$(echo $libpath)build/jar/myjar.jar" org.....Startup

将被抛出的异常

WARNUNG: Class org....facade.ServiceFacadeImpl is ignored as an instance is registered in the set of singletons
Call getMutationList: NP_005378
Exception in thread "pool-1-thread-1" java.lang.IncompatibleClassChangeError: Class javax.ws.rs.core.Response$Status does not implement the requested interface javax.ws.rs.core.Response$StatusType

我门面的一部分

@GET
@Path("/mutations/{id}/{from}/{size}")
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public MutationPosContainer getMutationList(@PathParam("id") String id,
        @PathParam("from") Integer from, @PathParam("size") Integer size) {
    ...
    if (posContainer == null)
        throw new BadRequestException();
    else
        return posContainer;
}

应用程序处理程序

public class SnapDbApplication extends Application {
  private ServiceFacade facade;

  public SnapDbApplication(ServiceFacade facade) {
      this.facade = facade;
  }

  @Override
  public Set<Class<?>> getClasses() {
      Set<Class<?>> s = new HashSet<Class<?>>();
      s.add(this.facade.getClass());
      return s;
  }


  @Override
  public Set<Object> getSingletons() {
      Set<Object> s = new HashSet<Object>();
      s.add(this.facade);
      return s;
  } 
}

编辑:classpath

您的类路径中可能有jsr311的不兼容版本(请参阅1)。删除它,它应该运行正常。
