jbuilder写applet,用了xylayout,dataset等，怎样发布呢

[ppzhao]

jbuilder里可以看

出来就不可以了，怎样发布它呢？

[Symanteck]

直接将html文件在ie中打开，如果applet显示不对是路径得问题

[Symanteck]

在applet中不一定能访问数据库，没试过。
最好不再applet中do this

把jb\lib\jbcl.jar放到你的classpath中就可以了！
告诉你一个最好的方法！！！其实他就用到了两个类文件
代替你的com.borland.jbcl.*
就哦ok!!!1

还有个这个怎么办？
如何给别人也能运行，没人改classpath太麻烦了
每个客户端还要有jbcl.jar
怎么办？！？！

[ppzhao]

jbuilder打包，就可以了

[copyright]

直接选择打包工具，将需要的文件jar到一起，
然后再html里面德applet中加一个参数
加上archive="xxx.jar"就行了
