Java操作MS Word和Excel文档

能通过Java来操作Word或者Excel的api，据我所知的有这些，都考察了一下，开源的除了Openoffice和officewriter对Word的表格有好的支持外，其他都很不专业，或者不支持。

Aspose.Words http://www.aspose.com/ 付费产品
Aspose.Words for Java, it runs on any OS where Java is installed.
It will output the document to DOC, DOCX or RTF if you need an MS Word output format. All are supported equally well.
Using this API you can create a document from scratch, literally from nodes and set their formatting properties. You can also use a DocumentBuilder which provides higher level methods such as create a table row, insert a field etc. Or you can copy/join/move portions between existing pre created document, say you want to assemble a contract, just grab and copy pieces from several documents and Aspose.Words will merge styles, list formatting etc properly in the resulting document.
You will be able to insert a TOC field using Aspose.Words, but as of today, the TOC field will require a field update when the document is opened in Microsoft Word. However, we are going to release full support for TOC fields early in 2010. E.g. it will build complete TOC as MS Word does it.
