Question

我已经在websphere服务器中部署了我的应用程序，上周工作正常。

之后不会更改类文件和配置文件，但是现在当我尝试访问应用程序时出现错误

我无法理解为什么突然发生初始化失败。

我不确定问题是否是由于websphere服务器中的某些问题引起的？

Answer 1

运行时类路径中缺少包含com.klm.solution.cargo.webpearl.library.Debug的JAR，真的没什么可说的，只需检查你的编译和＆amp;运行时类路径匹配。

Answer 2

根据你的堆栈跟踪，检查这一行在com.klm.solution.cargo.webpearl.library.USRUserAutherization.getSSOID(USRUserAutherization.java:109) 你可以找到线索。

Answer 3

我已经在调试模式下重新启动了服务器并检查了问题并开始工作。这很奇怪

java.lang.NoClassDefFoundError :(初始化失败）
