I´m working on a big application and we use Mavem bundle plug in in our proxy to make it small! I´m having problems importing some needed library for handling some kind of images (jpeg2000 and jbig2) needed by PDFbox.

Here is my pom (part of it)

I fixed the Import Package and i dont have The warnings anymore!

Here is my nethod where pdfBox uses those libraries and i get an exception inthe try/catch block!

private static boolean checkPDFImagesSize(PDDocument document) {
PDPageTree list = document.getPages();
PDXObject o;
for (PDPage page : list) {
    PDResources pdResources = page.getResources();
    for (COSName cosName : pdResources.getXObjectNames()) {
        try {
            o = pdResources.getXObject(cosName);
        } catch (IOException e) {
            throw ProxyRuntimeException.of(ExceptionCodes.ERROR_GENERATING_PDF_IMAGES);
        }
        if (o instanceof org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject) {
            if (((PDImageXObject) o).getHeight() * ((PDImageXObject) o).getWidth() * ((PDImageXObject) o)
                    .getBitsPerComponent() * 3.0 > ALERT_IMAGE_SIZE_INSIDE_PDF) {
                return false;
            }
        }
    }
}
return true;

}

When debuging in IntelliJ i got this!

  • Do you get any import errors in Apache Felix Console (/system/console/bundles)? Are the imports you defined in the manifest satisfied? Commented Apr 21, 2017 at 15:45

  • You can check that in the Apache Felix Console that you find at http://<domain>:<port>/system/console/bundles. There you can click on the bundle to see if all required classes could be imported.

I was looking at the wrong issue! The problem was not in the JPEG2000/JBIG2 dependencies but in the javax.imageio.spi.ServiceRegistry which has a none issue with ServiceLoder in OSGi and is called from PDFBox. As here is described: OSGi java.Util.ServiceLoader

So i had to implement this solution. OSGi Aries spi-fly
