(It is mainly to achieve online reading of word/excel/ppt. I have also checked a lot of materials on the Internet. Office cannot read them directly. It is necessary to convert the formats to read them. I have seen two formats several times, one is swf, the other is HTML. There are many jar packages to convert. I adopted one of the methods, openoffice swftool. With this method, it is necessary to install openoffice and swftool, and start the openoffice service at the same time. After the instance is downloaded and imported, change the index The way in the jsp can be solved. If you come to our Open Source, there will be materials or software you need, tutorials, patches, source code, etc)
