java.lang.NoSuchMethodError在WebSphere 7

Question

我到一個奇怪的問題中運行，

我有彈簧2.5開發的Web應用程序。

我將這個應用程序部署在websphere 7應用程序服務器。

有兩個WebSphere應用服務器，應用程序正常工作在一個應用程序服務器，但在另一方面，它給出了一個奇怪的錯誤說，Web應用程序正在爲一個不存在的方法的調用。

java.lang.NoSuchMethodError: com.dfn.mtr.mix.beans.PortfolioRecord.getPendingSell()J

實際方法調用應用程序製作是，

com.dfn.mtr.mix.beans.PortfolioRecord.getPendingSell() 

我附下面日誌的一部分。當我爲這個問題搜索時，我找不到任何解決方案，希望你們可以給我一些幫助以解決問題。 如果您想了解有關此問題的更多信息，請讓我知道。

問候， Rangana

Answer 1

在大多數情況，這意味着你的jar版本不對應一個。
您需要驗證它們的版本是否正確。

我想這樣做的原因是當加載所需的類classloader時，因爲該類存在沒有其他錯誤，它可以加載到JVM中。
但是，當您調用該方法時，它會失敗，因爲在此版本的jar中可能沒有必需的方法。

請檢查方法getPendingSell()在這個類com.dfn.mtr.mix.beans.PortfolioRecord

如果您不能手動找到它，你現在可以做進一步的探索！

Answer 2

我建議要做的第一件事是： 轉到目錄HOME_OF_YOUR_WAS_PROFILE \ installedApps \ YOUR_APP_NAME並檢查那裏的jar文件。試着檢查你的庫，它們可能在耳邊或在戰爭檔案中。它們在兩臺服務器上必須相同。

如果您使用Windows作爲您的操作系統，請考慮Websphere 7在卸載時有時不清除應用程序目錄。當你改變你的庫的版本時，這是很常見的情況：

1）例如有一個lib文件lib1-3。 2.0 .jar。 2）您將其更改爲lib1-3。 3.1 .jar在您的應用程序中。 3）您卸載您的應用程序並安裝新版本。 4）這兩個文件都在你的lib路徑中，這就是你遇到的問題。
