Hmm.. ideas.. I noticed that I had to import javax.naming to get rid of
another error I saw before. So I wondered if there might be more imports
that Karaf doesn't provide out of the box that standard Java does.
After some looking through HikariCP source code I found several import
statements that could be a problem. And now my Import statement looks
like this:
Import-Package: org.osgi.framework, javax.naming, org.slf4j, javax.sql
, javax.management
Now I'm getting entirely new errors so I'm guessing the problem has been
solved for that class.
The error I'm getting now is:
Caused by: java.lang.ClassNotFoundException:
org.apache.commons.pool2.impl.DefaultEvictionPolicy
I'm starting to feel that Karaf lacks so many classes that most
libraries I'm importing might be missing dependencies. Is it possible to
import all of javax? Or is there some default list that will make Karaf
provide the same list as standard Java?
