can't import derbyclient bundle [message #633353]

I am getting exceptions while trying to import derbyclient 10.6.2000001.999685 .

When I do

Import-Bundle: derbyclient

I get

Caused by: org.eclipse.virgo.kernel.osgi.framework.UnableToSatisfyBundleDependenciesException: Unable to satisfy dependencies of bundle 'com.rits.derby' at vers
ion '1.0.0': Import-Bundle with symbolic name 'derbyclient' in version range '[0.0.0, oo)' could not be satisfied
	at org.eclipse.virgo.kernel.userregion.internal.importexpansion.ImportExpansionHandler.getBundlePackageImports(ImportExpansionHandler.java:271)

When I do

Require-Bundle: derbyclient;version="[10.6.2000001.999685]"

I get

Caused by: org.eclipse.virgo.kernel.osgi.framework.UnableToSatisfyBundleDependenciesException: Unable to satisfy dependencies of bundle 'com.rits.derby' at vers
ion '1.0.0': Cannot resolve: com.rits.derby
    Resolver report:

	at org.eclipse.virgo.kernel.install.pipeline.stage.resolve.internal.QuasiResolveStage.process(QuasiResolveStage.java:45)
....

I do have derby client in my maven repository and I've configured virgo to read bundles from it. This works because I import other bundles from it.

			<dependency>
				<groupId>org.apache.derby</groupId>
				<artifactId>derbyclient</artifactId>
				<version>10.6.2.1</version>
			</dependency>

Any ideas?

Thanks

Require-Bundle: derbyclient;version="[10.6.2000001.999685]" is invalid syntax. Did you mean Require-Bundle: derbyclient;version="[10.6.2000001.999685, 10.6.2000001.999685]"?

What is the Virgo repository configuration for the Maven repository?

Hi, tried with

Require-Bundle: derbyclient;version="[10.6.2000001.999685,10.6.2000001.999685]"

and I got

Caused by: org.osgi.framework.BundleException: The bundle "com.rits.derby_1.0.0 [72]" could not be resolved. Reason: Missing Constraint: Require-Bundle: derbycl
ient; bundle-version="0.0.0"
	at org.eclipse.osgi.framework.internal.core.AbstractBundle.getResolverError(AbstractBundle.java:1317)
	at org.eclipse.osgi.framework.internal.core.AbstractBundle.getResolutionFailureException(AbstractBundle.java:1301)
...

my org.eclipse.virgo.repository.properties :

ext.type=external
ext.searchPattern=repository/ext/{artifact}

usr.type=watched
usr.watchDirectory=repository/usr

mavenrepo.type=external
mavenrepo.searchPattern=${user.home}/.m2/repository/**/{bundle}.jar

mavenrepolibd.type=external
mavenrepolibd.searchPattern=${user.home}/.m2/repository/**/{bundle}.libd

chain=mavenrepo,mavenrepolibd,ext,usr

this should be ok because I am importing other bundles from the mavenrepo. derbyclient is under /home/ariskk/.m2/repository/org/apache/derby/derbyclient/10. 6.2.1 with a filename derbyclient-10.6.2.1.jar .

Cheers

Next, let's eliminate the possibility that ${user.home} is not being substituted properly by replacing it in the repository properties file with the value you would expect and restarting Virgo.

(BTW, this isn't relevant to this particular issue, but you should really keep ext and usr at the beginning of the repository chain as these are intended to be relatively stable repositories with ext containing some of Virgo's own dependencies.)

Oh, found what was wrong! Sorry for spending your time on this. An oversight on my side, somehow virgo wasn't aware of changes in the .m2 repo. Dunno why the -clean didn't work (I am always running virgo with the -clean). So -clean didn't work but as soon as I deleted everything under the work folder and restarted the server, the derby bundle was located just fine!

I am starting virgo within eclipse with these VM arguments:

-XX:ErrorFile=./serviceability/error.log 
-XX:HeapDumpPath=./serviceability/heap_dump.hprof 
-Djava.security.auth.login.config=./config/org.eclipse.virgo.kernel.authentication.config 
-Dorg.eclipse.virgo.kernel.authentication.file=./config/org.eclipse.virgo.kernel.users.properties
-Djava.io.tmpdir=./work/tmp 
-Dorg.eclipse.virgo.kernel.home=.
-Djavax.net.ssl.keyStore=./config/keystore 
-Djavax.net.ssl.keyStorePassword=changeit
-Xmx512m -XX:PermSize=256m

and these program arguments:

-config ./lib/org.eclipse.virgo.kernel.launch.properties 
-Forg.eclipse.virgo.kernel.home=. 
-Forg.eclipse.virgo.kernel.config=./config 
-Fosgi.configuration.area=./work/osgi/configuration 
-Fosgi.java.profile=file:./lib/java6-server.profile
-clean

I got those back from the springsource dm server days and updated them up to today. Is the -clean still valid?

Thanks

The crucial point here is that an external repository is only scanned when Virgo starts up and Virgo has not already indexed the external repository, so the restart of Virgo with -clean is necessary to delete the index and rescan to pick up the changes. See the user guide for details.

(Watched repositories are actively scanned and pick up changes without having to restart Virgo, but these are flat directories only and therefore not suitable for Maven repositories.)

Glad you are sorted now!

Just a comment -- surely you should have coded:

Require-Bundle: derbyclient;bundle-version="[10.6.2000001.999685,10.6.2000001.999685]"

that is, used the bundle-version attribute and not the version attribute.

That would explain the message:

Missing Constraint: Require-Bundle: derbyclient; bundle-version="0.0.0"

referring to version 0.0.0 (which you 'specified').

I don't think if affects the rest of the discussion, however. Smile

I've restarted the virgo server with the -clean but still it couldn't locate the derbyclient bundle. Had the issue for a couple of days and in 2 PC's and I did several restarts. Anyway,I'll give it a try with a new bundle to see if it actually reoccurs.

I use

Import-Bundle: com.springsource.org.apache.log4j;version="[1.2.15,1.3.0)"
,org.apache.commons.dbcp
,derbyclient

and that works. both versioned and unversioned bundles are loaded (I think unversioned means it will load the max version found)

I don't know the schemantics of Required-Bundle though - I don't use it. I suppose I used it incorrectly.

I just wanted to check the operating system of the PCs which were showing this problem as there are certain issues listing files in some circumstances under Windows.

An unversioned Import-Bundle has the same effect as coding version="0" which represents a range from 0 to infinity. The semantics of Import-Bundle are that it always chooses the highest bundle version available that fits in the specified range, which in this case equates to the highest bundle version available.

Require-Bundle is a little more complicated because its base semantics in OSGi are pretty complex and then there's Virgo's automatic provisioning behaviour as well. However, I don't think using version instead of bundle-version will have helped.

I use

Import-Bundle: com.springsource.org...

Thanks, useful info, I was never sure which version will virgo pick up from my .m2 repository - the old jar's are still there after I upgrade to newer version of libs.

Regarding my OS, I am using Ubuntu 10.10, JDK 1.6.0_21. I still didn't replicate the issue due to lack of time but will try in the next few days.

Ok, I can verify that -clean doesn't work as (I?) expect...

I've updated to RC1. I have a bundle of my own that imports an other bundle from the maven repository. I delete everything under virgo/work and start the server with the -clean. The bundle loads just fine.

Now I delete all under virgo/work and also delete the bundle under .m2/repository. I start virgo, my bundle can't find the deleted bundle.

I run mvn to re-download the deleted bundle.

I re-run virgo with -clean, my bundle still fails because can't find the bundle under .m2/repository

I delete all under virgo/work and restart virgo. Now all work ok.

Should I enter a bug?

I've attached my bundle. The bundle that I delete is the logback bundle:

maven stuff:

			<dependency>
				<groupId>org.slf4j</groupId>
				<artifactId>slf4j-api</artifactId>
				<version>1.6.1</version>
			</dependency>
			<dependency>
				<groupId>ch.qos.logback</groupId>
				<artifactId>logback-core</artifactId>
				<version>0.9.25</version>
			</dependency>

Yes, please log a bug. The strange thing is that -clean is meant to delete the work directory!

Ok, before I log a bug... is the -clean handled by the batch file that starts the server or by the java code? I am starting virgo within eclipse using a runconfig, which means java is called with the -clean parameter. So if it is handled by the batch file it is not a bug.

It's handled by dmk.sh/dmk.bat. If you use the Virgo tooling, there is an option to clean start the server.

aha, thats why it doesn't work for me. I was invoking java straight away with the -clean param. Not a bug then.
