关于velocity模板的一个问题

Java code

Velocity  [debug] Velocimacro : "velocimacro.library" is not set.  Trying default library: VM_global_library.vm2010/03/08 9:42:38 org.apache.catalina.core.ApplicationContext logVelocity  [debug] Could not load resource 'VM_global_library.vm' from ResourceLoader org.apache.velocity.tools.view.servlet.WebappLoader: 2010/03/08 9:42:38 org.apache.catalina.core.ApplicationContext logVelocity  [debug] org.apache.velocity.exception.ResourceNotFoundException: WebappLoader : Resource 'VM_global_library.vm' not found.    at org.apache.velocity.tools.view.servlet.WebappLoader.getResourceStream(WebappLoader.java:179)    at org.apache.velocity.runtime.resource.loader.ResourceLoader.resourceExists(ResourceLoader.java:224)

这是个什么问题啊，该怎么解决呢？

[解决办法]
Velocimacro：“velocimacro.library”未设置。 尝试默认的库：VM_global_library.vm




忘了什么配置？
