我正在尝试使用“IBM WebSphere Liberty Profile Tools for Eclipse”让现有的 Web 应用程序与“WebSphere Application Server Liberty Profile v8.5 Beta”一起使用。
我已经按照此处的说明安装了 Eclipse 的开发人员工具以及 liberty 配置文件运行时： https ://www.ibm.com/developerworks/mydeveloperworks/blogs/wasdev/entry/download?lang=en#comment-1321558450546
然后，我按照以下说明继续创建 Liberty Profile 服务器：http:
//publib.boulder.ibm.com/infocenter/wasinfo/beta/index.jsp?topic=%2Fcom.ibm.websphere.w4d.nd。 doc%2Ftopics%2Frw4d_dirs.html
我将我的 Web 应用程序添加到服务器并使用以下控制台输出启动它：
Launching TEST (was4d-1.0.0.20111202-0614/websphere-kernel_1.0.0) on Java HotSpot(TM) 64-Bit Server VM, version 1.6.0_26-b03
Boot properties: file:/home/tbuckley/work/WAS/was4d/usr/servers/TEST/bootstrap.properties
Config document: file:/home/tbuckley/work/WAS/was4d/usr/servers/TEST/server.xml
[AUDIT ] CWWKE0001I: The kernel was launched.
[AUDIT ] CWWKE0002I: The kernel started after 0.91
[AUDIT ] CWWKF0007I: A feature update is starting after 0.92 seconds.
[AUDIT ] CWWKZ0058I: Application monitor started after 1.218 seconds.
[AUDIT ] CWWKO0219I: TCP Channel http-default has been started and is now listening for requests on host localhost (IPv4: 127.0.0.1) port 9080.
[AUDIT ] SRVE9998A: Application myWebApp added to web container.
[AUDIT ] CWWKZ0001I: The application myWebApp has started successfully.
[AUDIT ] CWWKF0008I: The feature update is complete after 2.141 seconds.
当我通过浏览器点击网络应用程序 url http://localhost:9080/myWebApp/时，我得到一个空白页面和以下控制台信息：
[ERROR ] SRVE0015E: Failure to initialize Web application myWebApp
如果我重新加载页面，我会得到以下信息：
[WARNING ] SRVE0274W: Error while adding servlet mapping for path-->/login/*, wrapper-->ServletWrapper[Application Servlet:[/login/*]], application-->myWebApp.
[ERROR ] SRVE0015E: Failure to initialize Web application myWebApp
我的 web.xml 下还有以下 servlets/mappings：
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Application Servlet</servlet-name>
<url-pattern>/login/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
有什么想法可能是错误的，或者我如何获得更详细的调试信息？
更新
我刚刚在那里创建了一个骨架“动态 Web 项目”，并在其中放入了一个 index.html 文件。我将它添加到自由服务器，它通过转到 localhost:9080/simpleApp/index.html 来工作。
我要添加的现有动态 Web 应用程序非常庞大且复杂。我在 was4d/usr/servers/TEST/logs/ffdc/ffdc_12.02.16_16.40.33.0.log 下找到以下内容：

Web 应用程序中的弹簧设置似乎引起了一些问题？
谢谢
