MyEclipse中增加Tomca启动使用内存
window->preferences->myeclipse ->application server->tomcat 5->jdk->optional java jvm arguments里加:
-Xms256m -Xmx512m -Xss4M -XX:MaxPermSize=256m
-----------------------------

中文转16进制的指令： C:\Program Files\Java\jdk1.6.0_12\bin\native2ascii.exe -encoding gbk d:\a.txt d:\b.txt
-----------------------------

调试参数： -Xms256m -Xmx256m -XX:PermSize=128M -XX:MaxPermSize=300M
