通过 Eclipse 插件工具将 Web 应用程序添加到 WebSphere Liberty Profile

Question

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，我按照以下步骤继续创建 Liberty Profile 服务器这里的说明： http://publib.boulder.ibm.com/infocenter/wasinfo/beta/index.jsp?topic=%2Fcom.ibm.websphere.w4d.nd.doc%2Ftopics%2Frw4d_dirs.html

我将 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网址 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 servlet/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>

有什么想法可能是这里出了问题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“动态网络项目”框架，并在其中放入了一个index.html 文件。我将它添加到 liberty 服务器中，它通过访问 localhost:9080/simpleApp/index.html 来工作。

我试图添加的现有动态 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 下发现了以下内容：

Web 应用程序中的 spring 设置似乎导致了一些问题？

谢谢

Answer 1

事实证明，这是某些平台上 Spring 的问题（在我的例子中是 WebSphere liberty 8.5）。

从 Spring 3.1.0 M2 升级到 Spring 3.1.1 修复了该问题：
