About additional libs
If I put some jar lib into classpath and start felix. Can the bundles use the
packages and classes defined in this jar lib?

To state it more strongly, using boot class path delegation is typically
seen as a bad practice since it hides bundle dependencies and makes them
less reusable, which is why the system package approach is preferred.

The "-jar" option for the java command ignores the specified class path
and only uses the JAR file on the class path, so you need to do
something like:
java -cp mylib;./bin/felix.jar org.apache.felix.main.Main

OK. I've added my package name into the variable
org.osgi.framework.system.packages and then modified my importer bundle's
manifest file by adding Import-Package parameter.
But it still report the Exception:org.osgi.framework.BundleException:
Activator start error in bundle com.kortide.

No, not automatically. You have to list the package either as
bootclasspath packages (in the org.osgi.framework.bootdelegation
property) or as system packages (in the org.osgi.framework.system.packages).
What you choose is up to and depends on your use case. My preference is
to use system packages since such packages become regular exports of the
system bundle and content for package wiring like regular bundle exports.
