Question

我已经接管了具有以下规范的Web应用程序的开发和支持：

Java SE 1.6
Tomcat 6
Jersey 1.7

EDIT   我正在使用eclipse并使用eclipse运行该项目。不确定这是否有所不同。

EDIT   道歉。我使用的是球衣1.17.1而不是Jersey 1.7

此时我还没有使用Maven。我的新服务的web.xml条目是

  <servlet>
    <servlet-name>RESTService</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>com.sun.jersey.config.property.packages</param-name>
        <param-value>com.gy.restservices</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>RESTService</servlet-name>
    <url-pattern>/api/*</url-pattern>
  </servlet-mapping>

应用程序启动很好，但是当我调用我收到的服务时

org.apache.catalina.core.StandardWrapperValve invoke

我不确定是什么导致了这个问题。

我查看了this SO question，但它与部署到Google应用引擎有关。

好。这一个得到了解决。我从jersey-bundle-1.17.1.jar更改为jersey-bundle-1.19.1.jar，现在我的REST服务正在运行。

实现JAX-RS服务时接收java.lang.IncompatibleClassChangeError
