我必須通過添加寫入本地文件的功能來擴展現有的小程序。 我試過http://pscode.org/jws/api.html#fs的文件服務演示，發現它是我們需要的。 但我在Eclipse中運行它，在這裏我收到大量的（無奈的我）消息：如何在eclipse中運行java fileservice applet？

我已經搜索小時的網，並無法找到一個解決方案。什麼不見了 ？
如何在Eclipse中運行它？請問[this]（http://www.coderanch.com/t/525316/JNLP-Web-Start/java/Eclipse-run-JNLP）是否相關？ – maksimov
I'va將樣本添加到exixting程序中，並添加了對「savefile」例程的調用，該例程起作用：它顯示框架和按鈕，如獨立樣本中一樣。但是當我點擊「打開的文件」或「保存文件」按鈕時，我有這個消息列表。我將它作爲「java applet」運行，其他所有部分都正常工作。還有一個jnlp文件帶有樣本「FileAccess.java」，看起來像鏈接中的文件。我錯在哪裏？我忘了什麼？ – Louis
您是否嘗試將它作爲'Java Application'運行而不是作爲'Java Applet'運行？ – maksimov
