-----------------------------
Summary: Running Derby Network Server in an OSGi container
Key: DERBY-5863
URL: https://issues.apache.org/jira/browse/DERBY-5863
Project: Derby
Issue Type: Bug
Reporter: Pieter
Priority: Minor
I try to deploy the derby and derbynet bundles in an OSGi container and use it
as a Derby Network Server. The feature seems to be there, but I did not get it
working right away. I also could not find any documentation so I wonder if
anyone has actually done it? With some tweaks I got it working, but I think
some changes are needed.
The derby bundle does have an EmbeddedActivator that attempts to bootstrap
NetworkServerControlImpl (via DRDAServerStarter) to get an up and running Derby
Network Server. However, the derbynet jar containing NetworkServerControlImpl
is not an OSGi bundle.
So my first step was to wrap the derbynet jar and make it a bundle. That was
not enough, because NetworkServerControlImpl used derby internal classes which
are not exported by the derby bundle. I got around that by creating a
fragment-bundle that exports packages needed by derbynet:
{code}
Fragment-Host: derby
Export-Package: org.apache.derby.catalog,
org.apache.derby.iapi.db,
org.apache.derby.iapi.error,
org.apache.derby.iapi.jdbc,
org.apache.derby.iapi.services.i18n,
org.apache.derby.iapi.services.info,
org.apache.derby.iapi.services.io,
org.apache.derby.iapi.services.jmx,
org.apache.derby.iapi.services.monitor,
org.apache.derby.iapi.services.property,
org.apache.derby.iapi.services.stream,
org.apache.derby.iapi.store.access.xa,
org.apache.derby.iapi.tools.i18n,
org.apache.derby.iapi.util,
org.apache.derby.impl.jdbc,
org.apache.derby.mbeans,
org.apache.derby.security
Import-Package: org.apache.derby.impl.drda
{code}
With this fragment I am able to connect the the Derby Network Server.
Exporting these packages is not nice and I think a more elegant solution is
needed. Merging the derbynet jar into the derby jar would fix it, again not a
solution that will get much votes I think. Make derbynet a fragment of derby?
