I have started working with Japsper Report and feeling very good.I have few questions. 1) Let's say I have a field 'Salary' and some where down the report I want the SUM of all the salary. Is it possible through some functionality. Is a function like SUM available in JasperReport? 2) Do we have check box element in Jasper Report lik textbox and image? It would be great if somebody can point to link/reference.

You're correct. I have modify the code and now it works correctly. Thanks for your input. and you earned one karma. :) Code: Post Edited by vpandya at 07/04/2009 14:09

I took a bird's eye view into JRImageRenderer class from source code and found below code snippet, Code: Here, imageLocation variable is of String type but If I have passed an object of InputStream then how come imageLocation variable would get initialized?

Has anybody ever been able to display image on the report without saving it into local drive? I am working hard but no success since last three days. Various options to display image are net.sf.jasperreports.engine.JRRenderable java.lang.String java.io.InputStreamI have tried above three options. The second option works as I pass the path and image is stored in to local drive. But first and last option doesn't work. I get byte[] of image from database(blob --> byte[]) and I pass it to ByteArrayInputStream class. But it doesn't work. I have also tried JRRenderable option but no success. Can somebody tell me what am I missing? Code: PS : Size of imageByteArray is not zero. I have verified that. Post Edited by vpandya at 07/01/2009 15:09

I guess you are missing the Jasper Report Jar file or if it is present then it's not on the class path.

When I pass bais(ByteArrayInputStream),lr(JRRenderable) object reference as a parameter, it can't render the image rather it shows jasper report's default image. But when I pass fis(FileInputStream) object reference it renders the image correctly. Can somebody help me? Code: Post Edited by vpandya at 06/30/2009 17:33
