原因：java.lang.NoClassDefFoundError：org / apache / log4j / Logages in XPages

Question

现在在我们的XPages项目中，我们必须使用Quartz Scheduler。我尝试导入所有必需的jar，其中包括以下内容：

• c3p0-0.9.5.2
• log4j-1.2.16.jar
• quartz-2.3.0-SNAPSHOT.jar
• quartz-jobs-2.3.0-SNAPSHOT.jar
• slf4j-api-1.7.7.jar
• slf4j-log4j12-1.7.7.jar

我已经将所有罐子导入到我们的项目中，但是在加载页面（甚至不调用石英或任何东西）时，出现以下异常：

Error 500
HTTP Web Server: Command Not Handled Exception

在日志中，我看到：

我怀疑此问题与Axis 1.4 log4j-1.2.8.jar incompatible with XPages?有关

我已经尝试遵循建议并将以下内容添加到java.policy（部分授权codeBase）：

permission java.lang.RuntimePermission "setContextClassLoader";
permission java.lang.reflect.ReflectPermission "suppressAccessChecks";

但仍然没有运气。

怎么了？

提前感谢

我已通过添加所有日志记录库解决了该问题：

• log4j-1.2.16.jar
• slf4j-api-1.7.7.jar
• slf4j-log4j12-1.7.7.jar

至lib / ext
