jcom打印遇到超级难题，困惑中，求高手指点～～～
java＋Eclipse＋Tomcat7的环境下，利用poi作成Excel后，使用jcom调用默认打印机打印的时候，在Eclipse开发环境下能正常打印的，但是直接启动Tomcat7，打印就会出现异常了。现在的配置：jcom.jar放在calsspath下，jcom.dll放在java_home的bin下
不知道是哪里设置错了，还是漏了，已经困扰N久了，希望高手指点一下～～～
异常如下：
IDispatch::Invoke(0x783,1) failed HRESULT=0x80020009L
jp.ne.so_net.ga2.no_ji.jcom.JComException: IDispatch::Invoke(0x783,1) failed HRESULT=0x80020009L
