java.lang.NoClassDefFoundError:无法初始化类org.omnifaces.config.WebXml [英] java.lang.NoClassDefFoundError: Could not initialize class org.omnifaces.config.WebXml

问题描述

我最近在pom中添加了omnifaces 1.4.1，以使用某些转换器.

 < dependency>< groupId> org.omnifaces</groupId>< artifactId>多功能界面</artifactId>< version> 1.4.1</version></dependency> 

现在，对应用程序的每个请求都将引发一个始于

的异常.

  java.lang.NoClassDefFoundError:无法初始化类org.omnifaces.config.WebXml 

我正在使用的omnifaces.SelectItemsIndexConverter正常工作，但是对于每个请求都抛出此异常；甚至在不包含 onmifaces 组件的问题的页面上./p>

我的环境如下:

• Tomcat 7.0.37
• Mojarra 2.1.10
• PrimeFaces 3.4.2
• PrimeFaces扩展程序0.6.1

除了添加到pom之外，还需要其他一些设置吗?

解决方案

java.lang.NoClassDefFoundError:无法初始化类org.omnifaces.config.WebXml

当 WebXml >配置枚举在初始化期间无法解析Webapp的 web.xml 和/或 web-fragment.xml .但是，这应该引发了运行时异常.我将检查为什么它被吞下了.也许是特定于Tomcat的.

关于在特定情况下引发的运行时异常，

java.lang.ClassNotFoundException:avax.faces.application.ViewExpiredException

这表明您在 web.xml 中的内容如下:

 <错误页面>< exception-type> avax.faces.application.ViewExpiredException</exception-type>...</error-page> 

它应该确实是 javax.faces.application.ViewExpiredException .相应地修复它，然后 WebXml 将成功解析 web.xml .

I have added recently added omnifaces 1.4.1 to my pom to use some of the converters.

 <dependency>
    <groupId>org.omnifaces</groupId>
    <artifactId>omnifaces</artifactId>
    <version>1.4.1</version>
</dependency>

Now, every request to the application throws an exception which starts at

java.lang.NoClassDefFoundError: Could not initialize class org.omnifaces.config.WebXml

The omnifaces.SelectItemsIndexConverter I'm using is working fine, but this exception is being thrown for every request; even on pages that do not contain onmifaces components.

My environment is as follows:

• Tomcat 7.0.37
• Mojarra 2.1.10
• PrimeFaces 3.4.2
• PrimeFaces Extensions 0.6.1

Is there some additional setup that is required more than just adding to the pom?

解决方案

java.lang.NoClassDefFoundError: Could not initialize class org.omnifaces.config.WebXml

This will occur when the WebXml configuration enum failed to parse the webapp's web.xml and/or web-fragment.xml(s) during its initialization. This should however have thrown a runtime exception about that. I will check why it's been swallowed. It's perhaps Tomcat specific.

As to the runtime exception being thrown in your particular case,

java.lang.ClassNotFoundException: avax.faces.application.ViewExpiredException

This suggests that you've in your web.xml something like:

<error-page>
    <exception-type>avax.faces.application.ViewExpiredException</exception-type>
    ...
</error-page>

while it should really have been javax.faces.application.ViewExpiredException. Fix it accordingly and WebXml will then succeed in parsing the web.xml.
