在 Tomcat 5.5 中部署 web-app 时如何解决错误listenerStart？

发布于 2024-08-29 02:45:36 字数 1271 浏览 8 评论 0原文

我已将使用 Spring 和 Hibernate 的 Apache Wicket Web 应用程序部署到我的 Tomcat 5.5 实例。当我导航到 Tomcat Manager 界面时，我发现我部署的 Web 应用程序没有运行。当我按“开始”时，我收到以下错误消息； “失败 - 上下文路径 /spaghetti 处的应用程序无法启动”。

我的 catalina.log 包含以下内容：

Apr 15, 2010 1:51:22 AM org.apache.catalina.loader.WebappClassLoader validateJarFile  
INFO: validateJarFile(/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/jsp-api-6.0.16.jar)   - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/jsp/JspPage.class  
Apr 15, 2010 1:51:22 AM org.apache.catalina.loader.WebappClassLoader validateJarFile  
INFO: validateJarFile(/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/servlet-api-6.0.16.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class  
Apr 15, 2010 1:51:24 AM org.apache.catalina.core.StandardContext start  
SEVERE: Error listenerStart  
Apr 15, 2010 1:51:24 AM org.apache.catalina.core.StandardContext start  
SEVERE: Context [/spaghetti] startup failed due to previous errors

摘自 web.xml：

    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>

非常感谢任何帮助。

I've deployed an Apache Wicket web-application that uses Spring and Hibernate to my Tomcat 5.5 instance. When I navigate to the Tomcat Manager interface I see that the web-application I deployed is not running. When I press 'Start' I get the following error message; "FAIL - Application at context path /spaghetti could not be started".

My catalina.log contains the following:

Apr 15, 2010 1:51:22 AM org.apache.catalina.loader.WebappClassLoader validateJarFile  
INFO: validateJarFile(/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/jsp-api-6.0.16.jar)   - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/jsp/JspPage.class

Apr 15, 2010 1:51:24 AM org.apache.catalina.core.StandardContext start  
SEVERE: Context [/spaghetti] startup failed due to previous errors

Excerpt from web.xml:

    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>

Any help is greatly appreciated.

我发现遵循这些说明有助于找出问题所在。对我来说，那是杀手，不知道什么被打破了。

从链接引用

在 Tomcat 6 或更高版本中，默认记录器是“java.util.logging”记录器，而不是 Log4J。因此，如果您尝试添加“log4j.properties”文件 - 这将不起作用。 Java utils 记录器查找名为“logging.properties”的文件，如下所示：
http://tomcat.apache.org/tomcat-6.0-doc/logging.html< /p>
因此，要获取调试详细信息，请在 WAR 的“/WEB-INF/classes”文件夹下创建一个“logging.properties”文件，然后就完成了。
现在，当您重新启动 Tomcat 时，您将看到所有调试的全部内容！！！
示例logging.properties文件：

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

I found that following these instructions helped with finding what the problem was. For me, that was the killer, not knowing what was broken.

Quoting from the link

In Tomcat 6 or above, the default logger is the”java.util.logging” logger and not Log4J. So if you are trying to add a “log4j.properties” file – this will NOT work. The Java utils logger looks for a file called “logging.properties” as stated here:
http://tomcat.apache.org/tomcat-6.0-doc/logging.html
So to get to the debugging details create a “logging.properties” file under your”/WEB-INF/classes” folder of your WAR and you’re all set.
And now when you restart your Tomcat, you will see all of your debugging in it’s full glory!!!
Sample logging.properties file:

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/jsp-api-6.0.16.jar
/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/servlet-api-6.0.16.jar

您不应在 /WEB-INF/lib 中有任何特定于服务器的库。将它们留在应用程序服务器自己的库中。它只会导致类路径中的冲突。删除 /WEB-INF/lib 中的所有特定于应用程序服务器的库（以及 JRE/lib 和 JRE/lib/ext 如果您已将其中任何一个放置在那里）。

将特定于应用程序服务器的库包含在 Web 应用程序的库中的一个常见原因是，初学者认为这是修复不可解析的 javax.servlet 类等编译错误的正确方法。将它们放入 webapp 的库中是错误的解决方案。您应该在编译期间在类路径中引用它们，即 javac -cp /path/to/server/lib/servlet.jar 等，或者如果您使用的是 IDE，则应该集成IDE 中的服务器并将 Web 项目与服务器关联。然后，IDE 将自动在 Web 应用程序项目的类路径 (buildpath) 中获取特定于服务器的库。

/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/jsp-api-6.0.16.jar
/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/servlet-api-6.0.16.jar

You should not have any server-specific libraries in the /WEB-INF/lib. Leave them in the appserver's own library. It would only lead to collisions in the classpath. Get rid of all appserver-specific libraries in /WEB-INF/lib (and also in JRE/lib and JRE/lib/ext if you have placed any of them there).

A common cause that the appserver-specific libraries are included in the webapp's library is that starters think that it is the right way to fix compilation errors of among others the javax.servlet classes not being resolveable. Putting them in webapp's library is the wrong solution. You should reference them in the classpath during compilation, i.e. javac -cp /path/to/server/lib/servlet.jar and so on, or if you're using an IDE, you should integrate the server in the IDE and associate the web project with the server. The IDE will then automatically take server-specific libraries in the classpath (buildpath) of the webapp project.
