image in custom JasperReport .xml template

[sledgeas]

I have put an image, which is in the same directory as the template .xml file ($IREPORT_INSTALLATION/templates)

I refer to it as:
                <image  scaleImage="FillFrame" evaluationTime="Now" hyperlinkType="None"  hyperlinkTarget="Self" >
                    <reportElement
                        x="0"
                        y="0"
                        width="53"
                        height="44"
                        key="image-1"
                        stretchType="RelativeToBandHeight"
                        isPrintInFirstWholeBand="true"/>
                    <box></box>
                    <graphicElement stretchType="RelativeToBandHeight"/>
                    <imageExpression class="java.lang.String"><![CDATA["image.jpg"]]></imageExpression>
                </image>

I get errors (through e.g. iReport):

Error filling print... Byte data not found at location : .logo.jpg
net.sf.jasperreports.engine.JRException: Byte data not found at location : .logo.jpg     at net.sf.jasperreports.engine.util.JRLoader.loadBytesFromLocation(JRLoader.java:482)
...

Providing absolute path works. I also tried referring to it as ./image.jpg, .\image.jpg but nothing helped.

Thank you in advance.

Relative paths from .jrxml files to images (or other resources) do not work as you suppose they do (i.e. relative to the .jrxml file).  Instead, all relative paths are considered relative to the JVM current directory.

You can customize the way files are resolved by setting a value for the REPORT_FILE_RESOLVER parameter.

HTH,

Lucian

Thank you, I have resolved it by adding iReport/templates to the class path.

As I could not get any documentation of how to use REPORT_FILE_RESOLVER, but thanks anyway.

Case solved,
