再次提出Portal action问题

这次的问题是这样的，在不扩展jsr168的标准下，我是否能够将某一个服务器下的某个web程序拉到另一个服务器下的portlet中，而且还能正常跑起来？

比如，我现在创建一个门户，然后将yahoo,google的首页放到我的两个窗子里。然后点击查询的时候将结果显示在这些小窗子里

我现在的方案是模仿yahoo和google的页面，设计自己的portlet。然后将请求转发到这些网站再重新显示。

可能利用iframe也能够完成

除了这些技巧，有没有标准的办法？？

wsrp，这个只是听说过，没有用过

当然可以的
看来你们才开始研究portal的
plumtree到上面去找找的，实现起来很容易的

本人比较愚钝，请willmac讲讲好么？

咳,类似proxy的东西，什么都可以吃的
用于弱整合，不过这是我极力反对的，portal是内容管理和流程控制的容器的
是web容器的更高层次，而不是infomation hub.
多余的话，不说了，这些年说累了。
plumtree的代码贴出来，有用就拿去吧
ps:rss解决方案也类是的，不想改代码都可以用这个方案的
虽然这个代码有些suck的，也就一个思路的
嗬嗬，这个代码仅限google,自己的应用，自己写proxy的，看的时候注意

占个坑

呵呵，willmac的代码在有代理服务器的情况下就跑不动啦。还是用iframe好点。方便，省事。
