Applet錯誤java.lang.NoClassDefFoundError

我創建了一個運行junit測試的applet。當我從Eclipse中運行applet時，一切正常。當我嘗試將其嵌入到HTML中時，我正確地獲得了UI，但是當我單擊確定開始執行測試時，出現以下錯誤。Applet錯誤java.lang.NoClassDefFoundError

我包括我的所有類加一個的.jar所有externan jar文件和我使用它時，我打電話從HTML小程序。我的HTML是因爲它得到一樣簡單：

<html> 
    <title> Performance App </title> 
    <body> 
    <h2> Applet... </h2> 
    <applet code=lefty.AppletSetup.class width="200" height="200"  archive="performanceApp.jar"> 
    </applet> 
    </body> 
    </htmL>

此外，我不得不提到我的類中的一個延伸RunListener但我已經包含在我的類路徑和最終罐子的junit.jar。

此外，我不得不提到我的類中的一個延伸RunListener但我已包括在我的類路徑和最終罐子的junit.jar。

一些點作爲

A）你怎麼包括外部罐子到項目罐子？
B）classpath - 你的意思是一個util運行？
C）

造成的：拋出java.lang.ClassNotFoundException： org.junit.runner.notification.RunListener該行表示，類真正缺少因此，它是在項目罐子？

我想你不應該部署小程序單元測試代碼;僅僅因爲所有的單元測試都是針對IDE applet仿真運行的;所以儘量在沒有junit的情況下部署它

祝你好運
