java.lang.ClassNotFoundException：org.glassfish.jersey.servlet.ServletContainer，

帮助我解决此问题，我添加了记录日志的1.2 jar和jersey-bundle 1.18 jar。

    public Response getMsg(@PathParam("param") String msg) {  
        String output = "Jersey say : " + msg;  
        return Response.status(200).entity(output).build();

使用此web.xml servlet指令-更改必要的信息：

<servlet> <servlet-name>Jersey REST Service</servlet-name> <!-- Define ServletContainer of Jersey --> <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> <!-- Define the package to search for classes --> <init-param> <param-name>com.sun.jersey.config.property.packages</param-name> <param-value>com.javatpoint.rest</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>

java.lang.ClassNotFoundException：org.glassfish.jersey.servlet.ServletContainer异常
