Java报错，各位大神帮忙看看：java.lang.NoClassDefFoundError

Question

代码如下：
com.asiainfo.crm.open.base.bo.IOpenLogical iOpenLogical = IUcmCoreFactory.getICenterSV()._getICenterByBillId(aBillId);

上面代码执行时跳到下面代码，随后报错：
public static ICenterSRV getICenterSV() throws IOpenException,Exception{
return (ICenterSRV)OpenServiceFactory.getService( ICenterSRV.class );
}
