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

Question

我已經在websphere服務器上部署了我的應用程序，上週它工作正常。

類文件和配置文件之後沒有改變，但現在當我嘗試訪問該應用程序，我得到的錯誤

我無法理解爲什麼突然初始化失敗正在發生。

我不確定問題是否是由於websphere服務器中的某個問題引起的？

Answer 1

含com.klm.solution.cargo.webpearl.library.Debug的JAR是在運行時類路徑丟失，別的不多說真的，只是檢查，如果你的編譯和&運行時類路徑匹配。

Answer 2

根據您的堆棧跟蹤， 檢查此行 在com.klm.solution.cargo.webpearl.library.USRUserAutherization.getSSOID(USRUserAutherization.java:109) 你可以找到線索。

Answer 3

我已在調試模式下重新啓動服務器，並檢查問題並開始工作。這很奇怪
