I have seen in several threads here on stackexchange that this could be due to the LyX pipe. I have updated through the MiKTeX Package Manager the packages that could be updated. But then I got the error:Д¬aused by: net.sf.: Incompatible java.io.ByteArrayInputStream value assigned to parameter LOGO in the myReport dataset. I am using LyX 2.1.4 (latest version), JabRef 2.8.1 and Adobe Acrobat Reader DC.

If the image is put in a JAR, it must be sin some Java package reserved for images and other static resources. What you should do it to reference image files using their relative location within the classpath. Instead of getting the URL of image, I use the methode getResourceAsStream from the class loader to get the InputStream of the image, and set this to : printParameter('LOGO', imageStream), and in the template I have $P with java.io.InputStream as ImageExpressionClass. Hi, Using absolute paths to locate file resources is a bad idea, especially in J2EE applications. Would this be a problem for JR to traverse to the image? as you can see, the image lays within a. Then I omit the prefix jar:file: so I should get the absolute path of the image (shouldn't I?)Д«ut it seems that the template can't find this.Д¬aused by: net.sf.: Byte data not found at location : /opt/jboss-4.2.3.GA/server/instance1/tmp/deploy/tmp60550myApp.ear-contents/myApp-exp.war/WEB-INF/lib/module-print-1.1.0.jar!/printpackage/logo.png Jar:file:/opt/jboss-4.2.3.GA/server/instance1/tmp/deploy/tmp60550myApp.ear-contents/myApp-exp.war/WEB-INF/lib/module-print-1.1.0.jar!/printpackage/logo.png So I use the class loader of the class which will set the parameter, and using the method getResource on the relative path of the image, I managed to get the complete URL for the image as follows: Now I'd like to put an image for the report, and would like to try to provide this by using the absolute path of the image. I'm using JasperReport for a web application (jboss server on linux-based system), which generate some PDFs.

Jabref write absolute path
