我尝试以自下而上的方式实现 Web 服务。首先,我创建了一个动态 Web 项目并实现了一个使用 selenium 的功能。然后我将 selenium-server-standalone-3.23.0.jar 添加到项目的构建路径中。然后我将相同的 jar 文件添加到部署程序集中。然后我使用 Web 服务向导生成 Web 服务器和客户端。之后,我将相同的 selenium jar 文件添加到服务器的 WEB-INF/lib 文件夹并尝试运行该函数,该函数返回此异常:

然后我看了看控制台,看到上面写着:
May 21, 2013 8:45:09 PM org.apache.catalina.loader.WebappClassLoader validateJarFile
INFO: validateJarFile(C:\EclipseWorkspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\sonkezeko3\WEB-INF\lib\selenium-server-standalone-2.32.0.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class
这是什么原因造成的?我应该使用其他一些jar文件吗?服务器的代码如下:
