Finding resources in JasperReports
Images
Resources such as images that are attachments can be referenced using $P{RESOURCE_DIR}.
An image path would look like
$P{RESOURCE_DIR} + "image.jpg"
Resource bundles
Resource bundles are property files for translating reports into different languages.
By default iDempiere-JasperReports looks for a resource file with the same name as the JasperFile, ie, the Jasperfile is called Report.jasper and then it will look for Report.properties and Report_en_US.properties etc. This might be practical if you only have one single report and have no need to share translations between different reports.
NOTE! Idempiere doesn't handle resource bundles with country specific languange until after IDEMPIERE-1215 have been resolved.
