以下三种解决方法:

       1,从Intalled JREs里修改;window->Preferences->Java->Installed JREs,选择当前的JRE,然后edit它;在新窗口里设置Default VM Arguments为 -Xms128M -Xmx512M即可;这个设置应该对所有的工程都有效;

        2,如果仅仅是想对某个工程的有效的话,从Debug... 或Run...里修改,在(x)=Arguments里设置和上面相同的参数即可;

       3,如果小猫猫Tomcat的话,window->Preferences->Application Servers->Tomcat->Tomcat 6.x,选择JDK设置即可;

         大概就是这些设置,应该可以解决OutOfMemoryError: Java heap space的问题。
