Need help on javax.smartcardio [message #1743641]

Hi,
Have tried to deploy the bundle using javax.smartcardio.* to communicate with the smartcard on Kura and got the "java.lang.NoClassDefFoundError: javax/smartcardio/CardException".

Although added below virtual parameter to start_kura_background.sh
-Dorg.osgi.framework.system.packages.extra=javax.smartcardio,version=1.0, the problem was not solved.
Moreover, also tried to add the above parameter to either kura_custom.properties or config.ini, the issue still same.

Please help me on this issue.

NOTE: When tried to run the bundle as a standalone application, it was working fine.

Thanks.
Huy

Hi Huy,
could you give us some more details on your bundle and how it interacts with javax.smartcardio?
Did you import the Java.smartcardio package in the dependencies section of the MANIFEST.MF file?

Hi Matteo,

The bundle communicates with card by using javax.smartcardio.CommandAPDU and runs on equinox OSGI within eclipse without any error. Then, the bundle is deployed on Kura and gets the ClassNotFoundException.

Later, the bundle is simplified by removing everything and only importing the javax.smartcardio.CardException class in the Activator class, and the same issue still occurs when it is deployed on Kura. This showed that the javax.smartcardio.* are not seen by the bundle.

In the MANIFEST.MF, tried to import javax.smartcardio in Imported-Packages section, but it doesn't allow as this package doesn't export for reference in the bundle. Then I've try to import the package by using DynamicImport-Package section but got same issue.

I've confirmed that javax.smartcardio.* are inside in the rt.jar whose JDK is using by Kura.

Finally, got it working by adding the -Dorg.osgi.framework.system.packages.extra=javax.smartcardio,version=1.0 to kura/start_kura_background.sh, and adding javax.smartcardio;version="0.0.0";resolution:=optional to Import-Package.

Hello,
I tried to use javax.smartcardio in a Kura bundle, but I still have a ClassNotFoundException even with suggestions above.
I checked that javax.smartcardio package is available in my Java environment.
Any advice welcome!
Thanks
