POI Article

This article from Javaworld shows how easy it is to use POI. Cool - I'm sold!

Just for clarification the article only shows you HSSF. POI includes: HSSF, HDF, HPSF and POIFS. POIFS is OLE 2 Compound Document format which is the grand mama of the whole project. HSSF is the Excel Api.. Of course it stands for Horrible SpreadSheet Format (which is BTW fair. Excel format is illconceived...not nearly as ill-conceived as OLE 2 CDF itself...). I think you'll find that POI has excellent documentation for an opensource project. And you might enjoy this: http://jakarta.apache.org/poi/hssf/quick-guide.html or this: http://jakarta.apache.org/poi/javadocs/ (BTW clicking on a class in the javadoc lets you see UML class diagrams if you click on the upper right hand corner) -- also you might find the Source to the unit tests under "src/tests" to be pretty helpful. Unfortunately Centipede doesn't yet publish it in our online cross-referenced source code (http://jakarta.apache.org/poi/javadocs/javasrc/), however you can view it here (http://cvs.apache.org/viewcvs/jakarta-poi/src/testcases/). If you need assurance of the quality of our source code you should merely look here (http://jakarta.apache.org/poi/). We have ATM 375 unit tests... I'd bet most of the code is covered directly! Enjoy POI!
