用jbuilder8寫一個簡單Applet裡面包含database,queryDataSet,tableScrollPane,jdbTable database->connection Driver:sun.jdbc.odbc.JdbcOdbcDriver URL:jdbc:odbc:web 在jbuilder8可正常執行 用htmlconv1_3_0_01.jar將Applet1.html轉換 於WEB是執行會出現以下錯誤,哪裡有錯誤請各位大大釋疑!! The driver: sun.jdbc.odbc.JdbcOdbcDriver could not be loaded. This could be a problem with the driver itself, or that the driver is not found on the classpath. Stack Trace...

applet在取存有關檔案，資料庫上有安全上的考量 ，所以一般來說沒有經過簽章的applet是不能直接與 database連線的，要作簽署還要用另外的工具。 通常你想網路連到資料庫最理想的用法還是用JSP, 除非必要否則不要用applet去作有限制的工作。
