我正在研究java wicket框架和Apache tomcat.这里我有问题当我尝试
启动tomcat时它显示Java虚拟机启动器弹出窗口"无法创建
Java虚拟机".
单击Pop窗口上的"确定"按钮后,它会在控制台上显示错误.

VM初始化期间发生错误.
无法为对象堆保留足够的空间.

请给我任何参考或建议.
提前致谢.

我通过添加以下行来设置tomcat 7的堆大小 catalina.sh

export CATALINA_OPTS="-Xms512m -Xmx1024m"

然后停下来,启动了tomcat.但是当尝试使用命令jmap -heap获取堆大小时,我可以注意到内存不会改变:
