How can i view an image from a Blob column that contains an image file data with jasper reports?
Define an Image element in the report layout and set type to java.lang.Inputstream ,then bind element to the Blob column .
excuse me java.io.InputStream
i think this image viewer will help you view image, but i am not sure whether it is compatible with Blob column. maybe it will work.www.rasteredge.com/.../
