更改導致java.lang.NoClassDefFoundError的工作空間：org.apache.http.client.methods.HttpUriRequest

Question

我創建了一個新的工作區並從存儲庫加載了項目。

當我嘗試測試REST Web服務時，將項目發布到了Web Sphere，我得到以下異常（對於項目中的所有服務）。 當我從舊的工作空間發布它時，相同的代碼工作正常。 （兩個工作空間中的服務器實例相同）

Answer 1

好像您錯過了打包httpclient-XX庫的過程。 驗證新的war文件的（webroot）\\ WEB-INF \\ lib包含此jar文件

Answer 2

RAD似乎對可用的類感到困惑。 您可以嘗試從服務器中刪除應用程序，重新啟動服務器，然后重新添加應用程序。 甚至刪除服務器並重新創建它。

在多個工作空間上配置相同的Project和Server似乎不會引起任何問題，但是我想某些地方的某些元數據已損壞或混亂。 就像指向舊位置或其他東西一樣。
