我有一個RCP應用程序(簡稱RCP-APP)。我創建了一個包含媒體播放器api(.jar文件)的新插件(稱爲插件A)和一個媒體播放器api通過JNA訪問的C庫(dll)文件夾。然後我創建了另一個插件(稱爲插件B),其中包含依賴於插件A的媒體播放器應用程序。Eclipse RCP /插件問題
當插件B被激活時,我收到以下錯誤消息,通知我Plug-在B因找不到球員.DLL文件是媒體正在尋找:

如何告知插件B(或RCP-APP)的.DLL文件是在一個特定的文件夾中的插件A?
看來,api希望通過它的環境PATH變量找到.dll。
我該如何溝通「插件A /文件夾名稱」?
感謝您的協助。
」恕我直言,最好將直接訪問.DLL文件的所有代碼插入到插件A.這樣您就不需要將插件的內部文件結構公開給它的用戶。「 確實如此。但是,這推斷出我創建的每個插件都使用媒體播放器api,它將包含dll和.jar文件的副本,這正是我試圖通過放置.jar文件和。 – 2009-06-22 15:01:45
無論如何.....我api試圖通過PAT變量找到.dlls我誤以爲能夠將位置作爲參數傳遞給api – 2009-06-22 15:22:21
