Crontab运行java程序

如果你定时执行java程序，如果手动执行脚本没有问题，但是在crontab中确不执行那就要看看你的的shell脚本中是否引入和环境变量。网上有很多方法解决在crontab中引入环境变量的方法选一个方便省事的就可以了，下面是我用的：

#!/bin/sh
. /etc/profile
CLASSPATH=$CLASSPATH:/opt/javalib/antlr-2.7.6rc1.jar:/opt/javalib/asm.jar:/opt/javalib/asm-attrs.jar:/opt/javalib/cglib-2.1.3.jar:/opt/javalib/commons-collections-2.1.1.jar:/opt/javalib/commons-logging-1.0.4.jar:/opt/javalib/dom4j-1.6.1.jar:/opt/javalib/ehcache-1.1.jar:/opt/javalib/hibernate3.jar:/opt/javalib/jaas.jar:/opt/javalib/jaxen-1.1-beta-7.jar:/opt/javalib/jdbc2_0-stdext.jar:/opt/javalib/jta.jar:/opt/javalib/log4j-1.2.11.jar:/opt/javalib/mysql-connector-java-5.0.5-bin.jar:/opt/javalib/xerces-2.6.2.jar:/opt/javalib/xml-apis.jar:/opt/javalib/proxool-0.9.1.jar:/opt/javalib/proxool-cglib.jar
export CLASSPATH
cd /opt/InputHint
java -server -Xmx256m -Xms256m com.ku6.inputhint.logicnew.InputHintExecute >> stdout.log
