开发完项目以后，部署到服务器上的时候，出现的问题如下（本地运行正常）：

解决问题的方法：

直接在我的帐号zhang下面对tomcat进行重新启动操作还是不可以，说是logs没有权限访问。然后我把logs chmod 777以后，还是不可以。

就在root帐号下重新配置了一下环境变量，然后重启了tomcat，问题解决了。但是不知道为什么这样就可以了

操作如下：

第一、切换到root用户下；

第二、[root@wn7-lcg bin]#vi /home/lxm/.bash_profile
第三、加入如下配置
#2012-12-10 zhangshibo add
export JAVA_HOME=/usr/local/jdk1.7.0_03
PATH=$PATH:$JAVA_HOME/bin;

第四、立即生效

[root@wn7-lcg bin]# source /home/lxm/.bash_profile

第五、重启tomcat
[root@wn7-lcg bin]# ./shutdown.sh
