Hi there, I'm using POI 1.5.1 because this is the latest release, and I was told that this is a quite stable one while newer ones would not be as stable.
In the PDF docs it is explained that custom data formats can be built with the method createDataFormat of the class HSSFWorkbook. Unfortunately, in 1.5.1 it seems that this method does not exist in this class. In Google I found that this method was introduced in 1.11.0 . Is this really the case? Do I have a chance to create custom data formats with 1.5.1 in a different way? Or did I miss something? Or do I need to use a new version? Kind regards, Christian
