使用velocity启动项目报错

启动tomcat时，出现
2007-3-15 16:42:42 org.apache.catalina.core.ApplicationContext log
信息:  Velocity  [error] ResourceManager : unable to find resource 'VM_global_library.vm' in any resource loader.
2007-3-15 16:42:42 org.apache.catalina.core.ApplicationContext log
信息:  Velocity   [info] Velocimacro : error using  VM library template VM_global_library.vm : org.apache.velocity.exception.ResourceNotFoundException: Unable to find resource 'VM_global_library.vm'
2007-3-15 16:42:42 org.apache.catalina.core.ApplicationContext log
信息:  Velocity   [info] Velocimacro :  VM library template macro registration complete.

在goole 搜了很多，发现有这样一个回答

Absence of 'VM_global_library.vm' does not cause the build to fail. Its a
standard velocity message and you should ignore it, if you are not using
velimacros.

[error] ResourceManager : unable to find resource ‘VM_global_library.vm’ in any resource loader.

 

velocity.log出现这样的错误：
Mon Jan 17 10:21:14 CST 2011 [error] ResourceManager : unable to find resource ‘VM_global_library.vm’ in any resource loader.
Mon Jan 17 10:21:14 CST 2011 [info] Velocimacro : error using VM library template VM_global_library.vm : org.apache.velocity.exception.ResourceNotFoundException: Unable to find resource ‘VM_global_library.vm’
但是，项目可以正常启动，运行，
而且整个项目中都没有VM_global_library.vm字样，看来是普遍问题了。
baidu一下，google一下，发现
Absence of ‘VM_global_library.vm’ does not cause the build to fail. Its a

也有的说是struts的版本问题，不管他了

还有一种解决方法：
直接修改Velocity的jar包里的属性文件即可，方法如下：
1）进入velocity-1.5.jar
2）打开org\apache\velocity\runtime\defaults\velocity.properties
3）修改内容如下：
runtime.log.logsystem.class = org.apache.velocity.runtime.log.NullLogSystem

以后再也不会有velocity.log文件出现了，也不会有找不到Log类的方法，更不需要添加这个logkit的jar包了。
