loading .jasper files saved on .jar

2004-08-06 08:18

Hi all, does anybody could tell me if it is possible to pack .jasper files on jar files and then to load them from there (the jar file without unpacking) in order to have all the resources on one jar file.

Thanks in advance.

 

Mauro.

simply put your file in a folder you can track from the jar and use the JRLoader class to load it; for instance if my report is "Report.jasper" and the path to it from the root of the jar file is "report/Report.jasper", i'll simply do

 

JRLoader.loadObjectFromLocation("report/Report.jasper")

Well try this to load a jasper-file from your jar-archive:

 

JasperReport jr = null;

String reportDir = new String("/reports/templates/"); // your directory structure within the jar - see with the class beyond

String reportFileName = new String ("YourTemplateReportName");

String reportExt = new String(".jasper");

String reportString = ((DruckDokument.class.getPackage().getName()).replace('.','/')+reportDir+reportFileName+reportExt).toLowerCase(); // DruckDokument is my current class i'm loading the reports from just to get my package-structure you must place your own class here

Class c = getClass();

ClassLoader cl = c.getClassLoader();

URL u = cl.getResource(reportString);

if (u != null){

InputStream is = u.openStream();

jr = (JasperReport) JRLoader.loadObject(is);

}else

throw new AfpsException("Could not load PrintTemplate from JAR-Archive ("+reportString+")!");
