遇到TOMCAT出錯(cuò)：java.lang.OutOfMemoryError: Java heap space，于是查了資料，找到了解決方法：
If Java runs out of memory, the following error occurs:
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
Java heap size can be increased as follows:
java -Xms<initial heap size> -Xmx<maximum heap size>
Defaults are:
java -Xms32m -Xmx128m
如果你用win
/tomcat/bin/catalina.bat 加上下面的命令:
set JAVA_OPTS=-Xms32m -Xmx256m
如果你用unix/linux
/tomcat/bin/catalina.sh 加上下面的命令:
JAVA_OPTS="-Xms32m -Xmx256m"
