How to show an image on jasper report?
- by spderosso
Hi,
I want to show an image on a jasper report. I have the following on the .jrxml:
<image>
<reportElement x="181" y="0" width="209" height="74"/>
<imageExpression class="java.lang.String"><![CDATA["logo.jpg"]]></imageExpression>
</image>
The image logo.jpg is in the same directory as the .jrxml. By just putting that it didn't work for me. I googled a bit and found out that jasper report considers what i put on the .jrxml as a relative path to the JVM directory and that to change this I need to pass as a "REPORT_FILE_RESOLVER" parameter a FileResolver that returns the file. So, I did the following in my .java (is located in same place as the .jrxml and the image)
FileResolver fileResolver = new FileResolver() {
@Override
public File resolveFile(String fileName) {
return new File(fileName);
}
};
HashMap<String, Object> parameters = new HashMap<String, Object>();
parameters.put("REPORT_FILE_RESOLVER", fileResolver);
...
Which should return the expected file, but I still get a
net.sf.jasperreports.engine.JRException: Error loading byte data : logo.jpg
at net.sf.jasperreports.engine.util.JRLoader.loadBytes(JRLoader.java:301)
at net.sf.jasperreports.engine.util.JRLoader.loadBytesFromLocation(JRLoader.java:479)
at net.sf.jasperreports.engine.JRImageRenderer.getInstance(JRImageRenderer.java:180)
...
What am I doing wrong?
Thanks!
