将 JAX RS 应用程序部署到 Web Sphere 8.5 时找不到 Servlet 映射错误

Question

我是网络服务新手。已在 java 中使用 Eclipse 开发了一个简单的 rest web svc，Tomcat 遵循此 link. Application successfully runs on Tomcat but when i deploy it to IBM WebSphere 8.5.5. It deploys successfully but fails to start. I know its something with my Web.xml so i am adding it for rectification. Tried 但无济于事。

  <servlet-mapping>
  <servlet-name>Java WS</servlet-name>
  <url-pattern>/*</url-pattern>
  
  
  </servlet-mapping>
</web-app>

当我尝试启动应用程序时生成的 Web Sphere 日志是：-

0000112c ApplicationMg A   WSVR0204I: Application: TestWS_war  Application build level: Unknown

because of an mbean exception: com.ibm.ws.exception.RuntimeWarning:

我已经尝试了 Class 加载选项 Parent First 和 Parent Last 但无济于事。

Answer 1

它给出了 Class 路径中缺少“org.glassfish.jersey.servlet.ServletContainer”的错误。因此应用程序未启动。

看到与 WAS 8.5.5 兼容的 Jersey 版本了吗？（我认为是泽西 1.x）。需要使用对应的库

<servlet>
    <servlet-name>javax.ws.rs.core.Application</servlet-name>
</servlet>
<servlet-mapping>
  <servlet-name>javax.ws.rs.core.Application</servlet-name>
  <url-pattern>/rest/*</url-pattern>
</servlet-mapping>
