How to change the path of a JRImage?

I have an application that matters jrxml files to a database. In doing so, I would change the path of the report images to a default directory informed in the application. What I have so far is that

 

  JasperReport jr = ...;[/code]
for (JRBand band : jr.getAllBands()) {[/code]
    for (JRElement el : band.getElements()) {[/code]
        if (el instanceof JRImage) {[/code]
            File oldPath = new File(((JRImage) el).getExpression().getText());[/code]
            String newPath = new Preference("imgDir").getValue() + "/" + oldPath.getName();[/code]
            try {[/code]
                byte[] img = Tools.fileToByteArray(oldPath);[/code]
[/code]
                try (DataOutputStream dos = new DataOutputStream(new FileOutputStream(newPath))) {[/code]
                    dos.write(img);[/code]
                    dos.flush();[/code]
                }[/code]
            } catch (Exception ex) {[/code]
                Logger.getLogger(RelatorioC.class.getName()).log(Level.SEVERE, null, ex);[/code]
            }[/code]
            [/code]
            ((JRImage) el).setOnErrorType(OnErrorTypeEnum.BLANK);[/code]
        }[/code]
    }[/code]
}[/code]
 

Sorry for any error or discrepancy in the text, translated by google translate. Also unable to format the source code appropriately.

 

I appreciate any help.
