Flex与java交互，BlazeDS出现内存溢出

我java端查到数据后，并且把所有的图片加载成流的形式，返回到Flex端，报出了以下错误，实在不懂怎么着手解决；
[BlazeDS]Java heap space

Answer 1

我是用的是myeclispe
通过Preferences-->MyEclipse-->Servers-->Tomcat-->JDK
在Optional

Answer 2

调tomcat配置文件能给JVM调大一点，如果还是不能解决的话，就不要一下加载那么多

追问

这是传输的时候报出来的，和Tomcat的内存有关吗？

追答

你这明显是java虚拟机的问题 你既然说是flex 肯定是web项目 你不在tomcat里面配置 还能在哪配置？web项目是bs架构的，你难道还能去客户端配置么？
