java.lang.IllegalArgumentException: Width (0) and height (0) cannot be <= 0

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

参数值不在取值范围内,width和height不能小于等于0

[lanzhengwu]

很明显的错误。。顶楼上。。

[Maozhj]

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。

回复的都不在点上，这位是不是用的报表？

[ljiabin]

有没有人说点有用的，到底怎么解决啊！

[panzhou3333]

是啊，怎么解决呢
int w = img.getWidth(this) == 0 ? 500 : img.getWidth(this);
int h = img.getHeight(this) == 0 ? 300 : img.getHeight(this);
BufferedImage bi = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB);
有人是这么解决的。

同样的错误，但是我的原因是在struts.xml中使用了el表达式引起的
