RE: [equinox-dev] Trying to use DS
|
Aha! Yes well that would explain
it :-) The solution is that someone (doesn't have to be the system
bundle) needs to register that service. You can write a dozen-line
plugin to do it for you. All it has to do is instantiate a SaxParserFactory
and register it with that interface.

No, it doesn’t do this because
we are using a different FrameworkAdapter.
I’ll have to figure out how
to tell our FrameworkAdapater that the system bundle should register this
service.
Anyone want to give me pointers
on how to do that?

Launch with -console and examine the system bundle (type 'bundle 0'). It
should say:
osgi> bundle 0
System Bundle [0]
Id=0, Status=ACTIVE
Registered Services
{org.osgi.service.packageadmin.PackageAdmin}={service.ranking=2147483647,
service.pid=0.org.eclipse.osgi.framework.internal.core.PackageAdminImpl,
service.vendor=Eclipse.org, service.id=1}
{org.osgi.service.startlevel.StartLevel}={service.ranking=2147483647,
service.pid=0.org.eclipse.osgi.framework.internal.core.StartLevelManager,
service.vendor=Eclipse.org, service.id=2}
{javax.xml.parsers.SAXParserFactory}={service.id=3}
... and many more lines.

Looks like you don't have an XML Parser service available. You're
right that there should be a better error message. Probably eclipse
bugzilla would be the best place to report it.
The XML Parser service is usually registered by the system bundle if you're
running on J2SE. What JVM/JCL are you running on?

Thanks.
I actually figured that out five minutes after sending the message (of
course). Now however I am running across this:

I am trying to figure out what field I need to fill in in order to avoid
this NPE.
Also, this should be a bug somewhere. How do I file one?

DS uses CM if it is available but does not require it. It does require
the api package, but you can get that from the org.eclipse.osgi.services
plugin. Likewise the org.eclipse.osgi.services plugin includes org.osgi.services.component,
which is the DS api package.

Roy

| [equinox-dev] Trying to use DS |

I am trying to use DS. I ran into some trouble:
First, it wouldn’t start because it was looking for the configuration
manager import package. Since Equinox will not be providing that
service, I used a bundle from knopflerfish in order to get the CM service.
Then it would not activate due to this:
Error starting bundle: org.osgi.framework.BundleException: The bundle could
not
be resolved. Reason: Missing Constraint: Import-Package: org.osgi.service.compon
ent; version="0.0.0"
Where am I supposed to be getting that from?
