java.lang.NoClassDefFoundError: (initialization failure)
提问by user2369634
I have deployed my application in websphere server and it was working fine last week.
我已经在 websphere 服务器中部署了我的应用程序，上周它运行良好。
Class files and configuration files are not changed after that, but now when I try to access the application I get the error
之后类文件和配置文件不会更改，但是现在当我尝试访问应用程序时出现错误
I am not able to understand why suddenly the initialization failure is occuring.
我无法理解为什么突然发生初始化失败。
I am not sure whether the issue is due to some problem in websphere server?
我不确定问题是否是由于 websphere 服务器中的某些问题引起的？

The JAR containing com.klm.solution.cargo.webpearl.library.Debugis missing on the runtime classpath, not much else to say really, just check if your compile and & runtime classpaths match up.
com.klm.solution.cargo.webpearl.library.Debug运行时类路径中缺少包含的 JAR，实际上没有什么可说的，只需检查您的编译和运行时类路径是否匹配。

According to your stacktrace,
check this line
at com.klm.solution.cargo.webpearl.library.USRUserAutherization.getSSOID(USRUserAutherization.java:109)you can find the clue.
根据您的堆栈跟踪，检查这一行，com.klm.solution.cargo.webpearl.library.USRUserAutherization.getSSOID(USRUserAutherization.java:109)您可以找到线索。

I have restarted the server in debug mode and checked for the issue and it started working. This is very strange
我已在调试模式下重新启动服务器并检查问题并开始工作。这很奇怪
