about Packages Exported by Multiple Bundles
Hello,
Got a problem about Packages Exported by Multiple Bundles. There are 2 bundles exported org.apache.derby.jdbc package.
karaf@trun>install -s mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.derbynet/10.8.1.2_1
karaf@trun>install -s mvn:org.apache.derby/derbyclient/10.8.1.2
karaf@trun> list
[ 222] [Active ] [ ] [ ] [ 60] Apache ServiceMix :: Bundles :: derbynet (10.8.1.2_1)
[ 238] [Active ] [ ] [ ] [ 60] Apache Derby 10.8 (10.8.1000002.1095077)
karaf@trun> exports | grep derby.jdbc
222 org.apache.derby.jdbc; version="10.8.1.2"
238 org.apache.derby.jdbc; version="0.0.0"
Then, install a bundle with Import-Package like this:
Import-Package: javax.sql,org.apache.derby.jdbc,org.osgi.service.bluepri
nt;version="[1.0.0,2.0.0)",org.osgi.service.cm;version="[1.3,2)"
will throw a ClassNotFoundException:

If uninstall bundle 222, then, the app bundle will be installed successful.
How to process this kind of problem of package exported from multi bundles within karaf?
Thanks.

Hi,
No, the "Sealed" is from java spec, it requires that classes defined
in that package must be archived in the same JAR file, make it "true"
or "false" can't affect the OSGi behavior, because on top of this java
spec, the OSGi Specifications added the constraint that a package must
have a single source.

Thanks Freeman!
But even for the bundle declared not sealed ?
In the MANIFEST.MF of derbyclient:
Name: org/apache/derby/jdbc/
Sealed: false
Thanks.

Hi,
You really shouldn't install multiple bundles with same package and same version, otherwise you'll encounter the well-known split-package issue in OSGi container.
