Hi again:
I have the following error when I try to start my bundle in karaf:

Just to test out, I also tried including javax.activation in the
dependencies
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1</version>
</dependency>
and embedding it in the bundle
<build>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Embed-Dependency>activation</Embed-Dependency>
<Import-Package>
*;resolution:=optional
</Import-Package>
</instructions>
</configuration>
</plugin>
</plugins>
</build>
but, either ways, it does not work.
Have I misconfigured anything wrong, in this case?
Any inputs/pointers would be very helpful.
Thank you.
Regards,
Cooshal.
