将 JAX RS 应用程序部署到 Web Sphere 8.5 时未找到 Servlet 映射错误

Question

我是网络服务的新手。已经使用 Eclipse 在 java 中开发了一个简单的 rest web svc，Tomcat 遵循这个link。应用程序在 Tomcat 上成功运行，但是当我将它部署到 IBM WebSphere 8.5.5 时。它部署成功，但无法启动。我知道它与我的 Web.xml 相关，因此我将其添加以进行整改。尝试this，但无济于事。

当我尝试启动应用程序时生成的WebSphere日志是：-

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

Answer 1

它给出了类路径中缺少“org.glassfish.jersey.servlet.ServletContainer”的错误。因此应用程序没有启动。

查看与 WAS 8.5.5 兼容的 Jersey 版本吗？ （我认为是泽西 1.x）。需要用到对应的库。

<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>
