一般是什么引起的呢,为何在jre1.6中访问就不行,但是jre1.42、jre1.5下面就是正常的,是用jgraph开发的网络拓扑图查看

------解决方案--------------------
------解决方案--------------------
参数值不在取值范围内,width和height不能小于等于0
------解决方案--------------------
很明显的错误。。顶楼上。。
------解决方案--------------------
public class IllegalArgumentException extends RuntimeException抛出的异常表明向方法传递了一个不合法或不正确的参数。 所以很显然,你的Width (0) 和 height (0)是不合法的,参数必须>0。
