我已經使用Eclipse創建了一個java程序，並試圖在線運行它（這是一個簡單的遊戲）。我有自己的.class文件，程序運行端到端沒有問題。當我嘗試在網站上運行它時遇到問題。我用下面的代碼來嘗試，沒有運氣啓動它作爲一個applet：在網站上運行java類
<html>
<body>
<applet
code="Handler.class"
codebase="AlamoAdventure/"
name="Alamo Battle Adventure"
width="680"
height="509"
archive="Handler.jar"
id="Alamo Battle Adventure" >
</applet>
</body>
</html>
當我轉到它告訴我點擊的小程序詳細信息的網站。當我這樣做時，我得到一個彈出窗口，它給我一個RuntimeException：java.lang.reflect.InvocationTargetException
我錯過了什麼步驟讓它運行？ Handler.class和Handler.jar都在相同的位置。
主菜單java代碼如下：
/*
* Main Menu is the start up window that is displayed when the program starts. It has one button, "Start Game", and a randomly
* selected picture from a batch of 6.

你確定你寫的課程不在包裝下嗎？ – aksappy 2013-04-30 06:02:09
而且..該URL又在哪裏？順便說一句 - 代碼中的類聲明是什麼？ – 2013-04-30 06:06:08
