什么错误啊!粘出来
---------------------------------------------------------------
是javaScript的错把。你的onclick方法里面调用了savexml方法，而savexml没有定义（你现在定义的是jsp脚本里面的savexml方法）。
---------------------------------------------------------------
lileinlp(目空一切) onclick当然不能调用jsp脚本里面的savexml方法，java代码在页面初始化后，就不存在了，onclick只能调用js 写的函数
---------------------------------------------------------------
你应该把保存文件的功能方到另一个jsp文件里,通过request来传递内容
