最近看了Flex + LCDS + Java教程觉得不错，但是有个疑问，按照该教程建立的项目发布在安装有lcds的机 器上就可以进行java remoteobject的通信，可是如果将项目发布到没有安装过lcds的机器上好像不能使用remoteobject了，系统提示为“Error instantiating application scoped instance of type 具体的类名",可是如果将lcds自带samples发到没有安装过lcds的机器上的话，里面的实例一样可以运行java
remoteobject调用，向各位请教一下这是什么原因,该如何解决，谢谢了


开发用的环境为:myeclipse6+resin+flex3.0(插件版)+lcds2.5.1

具体的错误:
/*******************************************************/

谢谢了，问题解决了，是jdk版本造成的，谢谢您的回答

怎么 解决的能告诉一下吗 ？

lcds的自带sample里面已经包含lcds所需的库了，也就是说你部署了lcds-sample也就同时部署了lcds。

lcds在哪可以下载呀？

可能是你的jdk是1.6版本的造成的  改成JDK1.5就可以了

lcds到Adobe官方网站下载
