Aspose.Slides for Java 16.8.0 as OSGi bundle

Hi,


When I try to use Aspose.Slides for Java 16.8.0 as OSGi bundle, I get this exception:

java.lang.ClassNotFoundException: com.sun.imageio.plugins.jpeg.JPEGImageReader cannot be found by com.aspose.slides_16.8.0 at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:501)

Does this version of Aspose.Slides have some new dependencies on other libraries?

I had no problems with any of the previous versions of Aspose.Slides for Java.

Thanks,
Zeljko

With some testing on my side, it looks like the issue has been fixed. But I need a confirmation by you and your product team, since I don’t want to rely just on my tests.

Thanks,
Zeljko

Hi Muhammad,


The issue I previously reported has been resolved, but I have another problem using Aspose.Slides 16.11.0 in OSGi environment.

In my application, I work with dom4j library so I have to switch thread’s context class loader to org.dom4j.Document’s class loader to be able to use dom4j. Until Aspose.Slides for Java 16.11.0, I had no problem with loading presentations. With Aspose.Slides for Java 16.11.0, I’m not able to load presentation if I do the above context class loader switching.

Here’s a small test that gets executed in my OSGi (PaxExam) environment and fails to load the presentation.

public void asposeSlidesTest() {

ClassLoader old = Thread.currentThread().getContextClassLoader();
Thread.currentThread().setContextClassLoader(Document.class.getClassLoader());
try {

InputStream inputStream = new FileInputStream(“Bonn_DMV_Classification.ppt”);
Presentation presentation = new Presentation(inputStream);
inputStream.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
Thread.currentThread().setContextClassLoader(old);
}
}

This is the part of the stack trace with the exception:

java.lang.NullPointerException

at com.aspose.slides.FillFormat.setFillType(Unknown Source)
at com.aspose.slides.Presentation.final(Unknown Source)
at com.aspose.slides.Presentation.(Unknown Source)

What got changed in the latest Aspose.Slides release which prevents me loading presentations?

Can you check this?

Thanks,
Zeljko

Hi Zeljko,


I have observed the requirements shared by you and like to share that Aspose.Slides for Java has no dependency upon dom4j. Can you please test your application without using dom4j and using Aspose.Slides for Java 16.11.0 on your end. If there is still an issue then please share the sample project with us reproducing the issue on your end so that we may test that on our end.

Many Thanks,
