all the above bold letter files i am using for this task. but it is showing error in this line:

vehicleReportTask.run();

where vehicleReportTask is the RunAndRenderTask which is holding the png images to diplay in reports. This is how i am storing into task:

vehicleReportTask.setParameterValue("image", imgPath + filename);

its giving the same error from long time now, so if anyone can help me resolving this issue it would be veru much helpful to me. if anything required as an input feel free to ask. i can mail you of needed my email id is: vikramfartyal@gmail.com

Answer 1

java.net.MalformedURLException: no protocol means lack of protocol, like http:// of file:// .

Try to pass URL like this: file:///Softwares/new_tomcat/tomcat7/temp/jfreechart-299441806335424490.png by adding protocol prefix to imgPath .
