我下载了连接器.jar
驱动程序,并在服务器/lib
文件夹中找到它。我不明白会出什么问题
编辑:下面是我在worklight mobile browser simulator中运行应用程序时发布的控制台javascript消息

我解决了这个问题。我在
.xml
文件(是3306而不是3036)中编辑了url的端口,还更正了select()
中的函数select(语句)
下面两个文件更正

你在哪里找到接头的?你下载了哪一个?另外-尝试删除.jar并将其放回原处,它曾经帮助过我一次。@nute我解决了这个问题。我编辑了url的端口(是3306而不是3036),还更正了
select()中的函数select(statement)
?谢谢。@IdanAdar我有一个问题:如果我想在机器的同一lan上的真实设备上运行应用程序,我必须用lan中机器的ip更改
值,否则我必须做其他事情?你想做的是打开一个新的问题,并提供完整的细节。:)
