在将JAX RS应用程序部署到Websphere 8.5时，Servlet映射未发现错误

Question

我是web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遵循此链接。应用程序在Tomcat上成功运行，但当我将其部署到IBM WebSphere 8.5.5时。它成功部署，但未能启动。我知道我的Web.xml有一些问题，所以我添加它进行更正。尝试过，但没有成功。

当我尝试启动应用程序时生成的Web Sphere日志是：-

我已经尝试了两个类加载选项Parent First和Parent Last，但都没有用。

Answer 1

它给出的错误是"org.glassfish.jersy.servlet.ServletContainer"；类路径中缺少。因此应用程序没有启动。

看到与WAS 8.5.5兼容的Jersey版本了吗？(我想是Jersey 1.x(。需要使用相应的库。

<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>
