Hi, I discovered POI a few months ago and find it cool because most of my needs are covered by this library.
The context I work in : - 100% Java application on a webserver - POI 2.5 (I cannot use POI 2.0 since I use methods that don't exist in 2.0) - XLS templates (Excel 2000), sometimes with charts and macros. - A program merges a template with data extracted from an Oracle DataBase on the fly. - The newly created XL document is then sent to the end user. - When opening the document, the macro builds the final document, processing the data with a given set of parameters, building the final chart(s). So far, everything works fine (thanks !) BUT : - When I simply add a logo to my document (a gif/jpeg image for example), - The document processing seems to work fine - When I open the generated XL document, it seems to be corrupted and XL juste tell me "Unable to open document". I've written dozens of XL templates, from the more complicated to the most simple, and most of the time, the created file is just corrupted (depending on the input image i use). I've red things about that kind of problems, and answers about Escher objects, but even when I just have *a single image in an empty spredsheet*, the XL file becomes corrupted. Are there any specific limitations to the use of images in templates ? See an image that doesn't work in attachement. Thanks in advance for your help Julien, FRANCE.
