情况是这样的：一个DLL，已经在注册表注册了。如何通过读注册表Load Dll呢？怎样create 里面的class呢？VBA里是这样用的：
'Declare variables and constants
'Object variables
Dim MyMetabase As Object, _
MyQuery As Object, _
MyMetaCube As Object

'Excel variables
Dim ReportRange As Range

'Other variables
Dim MyData As Variant

'Constants
Const MyFirstAttribute = "Brand"
Const MyMeasure = "Units Sold"

'connectto a database
'Instantiate a Metabase object
Set MyMetabase = CreateObject("Metabase")//注册表里的KEY为"Metabase"

'Identify an ODBC data source
Let MyMetabase.ConnectString = "Metademo"
Let MyMetabase.Name = "MetaCube Demo"

'Specify database login name
Let MyMetabase.Login = "metademo"

'Specify database password
Let MyMetabase.Password = "metademo"

'Log in to demonstration database, open DSS System
MyMetabase.Connect

用JAVA如何做？请赐教！！！
