明显的java.lang.NullPointerException.
报这样的异常,只有在你的环境中才可以看到是什么参数造成的

各位哥哥，我现在也在用jboss portal，想把用ssh作的项目包成portal应用，可是我不知道怎么做，网上找了很多资料，例子，只有几个能跑通，谁能啊，啊！

大部分的例子只是出错，cannot found StrutsPortletInstance 之类的。而且，我把出错的war移走后，那些page 标签还在，生气！是不是与我用的与server绑定的版本有关啊，急！

jboss portal同liferay的实现原理差别较大。能力所限无法回答，请将该问题移到java主板。谢谢。
