引言: 如何用java或jsp讀取word當案的資料？使用COM Object試試 來源:http://www.alphaworks.ibm.com/forum/olebridge.nsf/archived/326C7A24514B7679899C062AA87A787B?OpenDocument Here are some listings of some classes I made when I was evaluating OLEBridge. You probobly need to view them with Netscape as MSIE doesn't seem to be able to show the text as preformatted. Here's a little GUI for trying out method calls on COM objects (it's hard coded to work with Word, but I've used it for playing with Lotus WordPro, too). Apologies for the UI and the lack of comments, but I found it quite useful. No introspection on the COM objects (as far as I could tell) means you have to find out method and property names some other way. the OLEView is not totally generic, but it can do some useful things, and I'm sure it could be augmented to be totally generic, if someone wants to put in the time. import com.ibm.olebridge.*;
