Pax exam test failing with gave up waiting for service org.ops4j.pax.exam.ProbeInvoker
I have a pax exam test that fails consistently with "gave up waiting for
service org.ops4j.pax.exam.ProbeInvoker" see exception below.
The strange thing is that just before this exception the pax exam probe
bundle finds my test and registers the ProbeInvoker service.
Any idea what is going on there?
I am using pax exam 4.13.0 and the native container.

Re: bundle not resolved due to pax-jdbc while provisioning in karaf
I dont think this is a race condition. Is it possible that your bundle has a requirement for the service and that pax-jdbc does not provide a suitable capability. (As pax-jdbc creates the DataSources from config there is no way how it could provide the capability). The reason why it might work with optional is that then there is no mandatory requirement. Does it help when you set serviceRequirements=default in the file org.apache.karaf.features.cfg ? Christian Am Mi., 8.

Re: Question to pax-jdbc devs: how do you handle DataSourceFactory bundle restart?
I see no calls to DriverManager in https://github.com/pgjdbc/pgjdbc/blob/master/pgjdbc/src/main/java/org/postgresql/osgi/PGBundleActivator.java It only registers and unregisters the DataSourceFactory service which looks correct. Not sure about the call to Driver.deregister though. This might cause the issue. Christian Am Mo., 29.

Further development of tinybundles
After the release of Tinybundles I wonder if we could remove the dependency to base store. The dependency seems innocuous at first but the problem is that base store is provided as a full base bundle in OSGi. So when you currently deploy tinybundles in OSGi you are quite tightly coupled to pax exam. I had to learn this the hard way when I tried to fix the bug with the left over directories and wondered why it did not seem to be fixed even when I deployed the new tinybundles and store. I took me a while to realize that pax exam brings the base bundle which makes it hard to change. So the first thing to decide is if we need the flexibility of store. After all the only thing tinybundles does with it is write a Inputstream to a file and get its url. It never really uses it as a store. So I think providing a directory for tinybundles where to store these files would be good enough. Unfortunately pax exam uses the bundle(Store) initialization. So we also would need to do that change in pax exam. Do we want to do this?

Planning releases of base and tinybundles in about two weeks
I recently worked on base and tinybundles. On base the main change is to make sure store does not leave files and directories behind. I also removed the dependency to base-io so store now does not have any dependencies besides the slf4j-api. For tinybundles I removed the file that was written when wrapping a bundle with bnd. I also did quite a few refactorings and also removed the dependency to base-io. So tinybundles now only needs base-store. I would be happy for some people to review my changes before the release.

[pax exam] Running code outside the OSGi container
I would like to have code executed outside of the OSGi container in the process where junit runs. This used to work with @BeforeClass in older versions of pax exam. Now these methods are also run in OSGi. Is there some way to run my code outside in a generic way? What I did until now is to extend pax exam an override the run method. Is there maybe a built in way that avoids this?

Some tipps and tricks for writing pax exam OSGi tests
I have just finished an example and docs of some tips and tricks I learned for writing OSGi tests using pax exam. Some highlights: - Mock tests for DS components using Mockito - Debug pax exam based tests like plain java code (edit, save, debug) - Full support for hamcrest matchers - Use Awaitility for polling asynchronous external systems - Create test bundles with bnd and DS components on the fly using TinyBundles - Use logback in pax exam See https://github.com/cschneider/osgi-testing-example Cheers Christian -- -- Christian Schneider http://www.liquid-reality.de Computer Scientist http://www.adobe.com -- -- -- OPS4J - http://www.ops4j.org - ops4j@googlegroups.com --- You received this message because you are subscribed to the Google Groups "OPS4J" group.

Re: Pax JDBC data sources are missing and never get resolved in a Karaf active/active configuration
To use ActiveMQ externally you still need to install the ActiveMQ client on karaf. Instead of the full activemq feature you only install activemq-client. You then also need to setup a JMS ConnectionFactory to connect to the external instance. This can be done using the regular karaf jms commands.

Re: Pax JDBC data sources are missing and never get resolved in a Karaf active/active configuration
Are the karaf instances on different machines? If they are on different machines and you do not use cellar or specially configured locking then both should come up completely independent from each other. Do you see anything in the log of the second instance when you stop the first one? I wonder what could trigger the data source come up in this moment.

Re: Pax JDBC data sources are missing and never get resolved in a Karaf active/active configuration
I am not experienced with cellar but generally I would expect that in an active/active setup both machines start the same services. So first thing to check is if the pax-jdbc features and bundles are active on the second node. If they are active you can check the log to see if pax-jdbc reports that something is missing. When you describe that the datasources on the second machine come up when the first machine goes down it sounds like you have setup something like a master slave setup in cellar.

Re: PAX Exam OSGI Components
Check out the ServiceComponentRuntime service. It is implemented by felix scr and allows you to introspect the status of any DS component. http://javadox.com/org.osgi/osgi.cmpn/6.0.0/org/osgi/service/component/runtime/ServiceComponentRuntime.html I am using this in my itests to list all components with unsatisfied references.

At Adobe we created a small project to start docker containers before a junit test and reliably stop them after the test. As this is of very general use I wonder if it would make sense to open source this. I am currently checking internally if we can do this. In parallel I also wanted to check if there are existing alternatives out there and if none are suitable as a replacement if the ops4j community would be interested to host such a project.

Missing licsense in pax project sources and releases
I am looking into this issue: https://ops4j1.jira.com/browse/BASE-40 I fixed the license in the binary package by using the same resource plugin as in tinybundles. We still have a gap though I think. 1. The source packages do not include a license. Does anyone know how to achieve this? 2. The source in github does not include a LICENSE file. Should I add it? Do we need to add more than that?

Problem with StreamFactory in base.store
I just tried to upgrade pax exam to the current snapshot of the base modules to test a change I plan to do in the exec module. Some of the tests fail with the exception below. This seems to be because of the introduction of StreamStore in base.store. This happens if a bundle like tinybundles 3.0.0 is compiled against base.store 1.5.0 but is then run with base 1.5.1. I propose to revert this commit and go back to Store. In general we should also think of ways to make us more independent of such changes in util modules. I have seen an approach in the brave project where they always embed util packages with a changes name to make it unique. I think this is a very good approach to make the code modular by minimising runtime dependencies. Unfortunately their approach does not work with the maven bundle plugin out of the box.

Re: pax exam: Problem with unwanted import when using TinyBundles with a custom BuildStrategy
Hi Christoph, I now experimented a bit more with the problem of .ClassNotFoundException: org.ops4j.pax.tinybundles.core.BuildStrategy. It seems the problem occurs when I use: InputStream inp = bundle().add(DsService.class).build(withBnd()); It seems the problem is that build(strategey) has a reference to BuildStrategy. So if we had .buildWithBnd() there would be no problem. Does it make sense to add this? (Even if I know it pollutes the nice abstraction a bit). Another possible solution would be to switch the default builder to bnd .. but this would create compatibility problems.

pax exam: Problem with unwanted import when using TinyBundles with a custom BuildStrategy
I am trying to tune TinyBundles to create DS xml for standard DS annotations. To achieve this I created my own BuildStrategy that adds the bnd plugin for DS. I only use this in the @Configuration so my test should not require TinyBundles at runtime. Still I get a ClassNotFoundException when I run the test (see below).

Re: Setup database structure before bundle under test is started with pax exam + karaf
You can use the new PreHook of pax-jdbc. It allows to run an OSGi service before the datasource is published. This can be used in production and test for db migration as well as for setup of a temp db before each test. This is an example for a migration hook: https://github.com/cschneider/Karaf-Tutorial/blob/master/liquibase/service/src/main/java/net/lr/tutorial/db/service/Migrator.java and this is how to use it in the config: https://github.com/cschneider/Karaf-Tutorial/blob/master/liquibase/org.ops4j.datasource-person.cfg Christian On 24.08.2017 09:36, karsten.bl...@hermes-ottoint.com wrote: Hello everybody, i am running pax exam 4 with a karaf 3 container.

Re: CDI?
On 15.08.2017 16:06, r...@enjekt.org wrote: Christian, I've also seen a lot of people using Processors/Exchanges which unnecessarily couples their cod to the Camel framework. Unfortunately the Camel in Action book doesn't get around to advising against that practice until your well over 100 pages into the books. And when it does it is in a bulleted list at the end of a chapter. When I'm at client sites it's one of the first things I teach them when mentoring developers. Use POJOs and unit tests just like any other code. Unfortunately neither the Camel website nor the Camel in Action book stress this and too many code examples use Processor/Exchanges unnecessarily. Honestly, in the past six years, I don't recall the last time I used Camel Processor/Exchange directly. I think you are on a very good track with this approach and it would be good to spread the word about it. As you wrote it is not emphasized enough in the camel book. So if you have a blog that would be a great theme. But services aren't more loosely coupled than messaging. If I have bundle A with all its classes unexported in ".internal" package and bundle B in the same situation but they communicate via Camel routes, that's decoupled at compile time and at runtime. Injecting a service interface whether it is through a proxy or not couples the two bundles at compile time and temporally couples them at runtime. If one puts the service interface into a separate bundle one now has a different dependency. Communicating externally is of course very loosely coupled. On the other hand remote communication is typically a lot more expensive than local communication using an OSGi service. Another problem with remote communication is also that it tends to make your domain model anemic. For the remote communication you need simple DTO like classes. So the logic is typically separated from the data. If this really is a problem typically depends on how complex your domain is. Your approach sounds a lot like a typical microservice approach. What I currently look into is combining domain driven design and microservices. I found that making each service in a bounded context a microservice is creating a lot of overhead. Instead I think it makes sense to use OSGi services to talk between bundles of the same bounded context. The border services that form the outside view of the bounded context are a good match for the camel endpoints you are using. Btw. What type of communication do you use? REST or more message based? One other thing I am looking into is how to separate the user code from the transport protocol. For this case jax-rs-whiteboard or Aries RSA with CXF might be interesting for you if you use REST or SOAP. It allows to offer and consume services without a direct dependency to camel or CXF. Unfortunately we do not yet have a good solution for one way messaging based communication / eventing. best regards Christian -- Christian Schneiderhttp://www.liquid-reality.de Open Source Architecthttp://www.talend.com -- -- -- OPS4J - http://www.ops4j.org - ops4j@googlegroups.com --- You received this message because you are subscribed to the Google Groups "OPS4J" group.

Re: CDI?
I agree. Not using services in OSGi is a bad idea. Services allow you to keep your bundles loosely coupled. You should also try to only use standard java types in your service interfaces. I have seen some cases where people share camel routes between bundles or use camel classes in service interfaces. In the start this seems fun but as your system grows you realize that the coupling badly hurts your ability to evolve parts of your system. Also when using services try to avoid retrieving a service and blocking until it is there. Instead let DS or another DI framework inject the service. Especially using DS this will make your system highly reactive to changes and even work when things are replaced at runtime like in development. It also copes well with refreshes like they happen a lot in apache karaf when you install features.

So this probe obviously can only be installed for the single test that also installs the bundle that provides the package.

Your method it seems interesting: you use <_include>bnd.bnd tag to decouple the pom.xml (maven information) with the information regarding OSGi. Since you're here can I ask you a couple of questions regarding your method: 1) What if I need to add a variable inside the bnd.bnd file? In maven I can use properties or I can override plugin behaviour. If I move my OSGi settings to the bnd.bnd file what kind of variable support do I have? 2) are you using bndtools with it (just curious)? You can use maven properties inside the bnd files. I am using bndtools but just as an editor for the bnd file. I also have an example where I use bndtools for packaging using bndrun files see https://github.com/cschneider/osgi-chat but I did not yet use this in production. So it is still a bit experimental.

Re: [pax-exam] gave up waiting for service
I think the problem might be the maven-bundle-plugin version. I updated
the version to 3.2.0 and it worked for me.
I also change the config to just this:
org.apache.felix
maven-bundle-plugin
${maven.bundle.plugin.version}
true
I think that the old plugin maybe does not fully work with the most
current DS annotations.
Btw. This is what I use most often now to create bundles:
https://github.com/cschneider/Karaf-Tutorial/blob/master/tasklist-ds/pom.xml#L107-L118
I then define the OSGi settings in bnd.bnd files if necessary. Like here
https://github.com/cschneider/Karaf-Tutorial/blob/master/tasklist-ds/model/bnd.bnd

As you can see in /microsi-root/pom.xml/ that project is *not used

examples/bundle-example-impl

Clearly, even removing the interface bundle and moving the

I think the the problem is about where the service interface

The service is created based on the interface from
bundle-example-impl but the itest depends on the

Re: Heads up: pax-jdbc-release 1.0.1 and redesign of trackers in pax-jdbc-config
Can you explain this in more detail? I would not expect any problems
with multiple connections using the same credentials.

Thanks Achim.
I went through the other issues in pax-jdbc and found this one:
https://ops4j1.jira.com/browse/PAXJDBC-106
<https://ops4j1.jira.com/browse/PAXJDBC-106>
It sounds like a serious issue with the aries pooling. So I think
we need to fix it before the release.

pax-jdbc 1.0.1 release
I would like to do a pax-jdbc 1.0.1 release today or
tomorrow. We fixed a bug in the hikari pooling and a user
asked for the fixed version.
There is also an open issue with the aries pooling. If
possible we should fix this for 1.0.1 but there is a workaround.
Can someone create a new pax-jdbc 1.1.0 release so I can move
issues to it?
See:
https://ops4j1.jira.com/projects/PAXJDBC/versions/22601/tab/release-report-all-issues
<https://ops4j1.jira.com/projects/PAXJDBC/versions/22601/tab/release-report-all-issues>
Avoid stacking trackers
For 1.1.0 I plan to redesign the trackers for pax-jdbc-config:
https://ops4j1.jira.com/browse/PAXJDBC-119
<https://ops4j1.jira.com/browse/PAXJDBC-119>
The problem we face at the moment is that pax-jdbc-config
depends on several other services and some of these are even
only needed depending on some of the config settings.
As we currently have to stack individual trackers to
implement these dependencies this is quite tedious and will
be more difficult with every new service we need to track.
So I designed a new generic MultiServiceTracker. This can be
configured with the services to track and will fire a
callback when all services are present. So it is a bit like
DS behaves but more configureable for services that are only
needed in certain cases.
I have committed the implementation into a new branch and
would be happy about feedback:
https://github.com/ops4j/org.ops4j.pax.jdbc/commit/fe1ad1a0a5dff12a5f0f3a287a260086d392251d
<https://github.com/ops4j/org.ops4j.pax.jdbc/commit/fe1ad1a0a5dff12a5f0f3a287a260086d392251d>
I plan to merge this after the 1.0.1 release.

Re: jdbc commands in BndTools?
To use any karaf commands you need to install the karaf shell instead of the felix gogo shell. Unfortunately the commands are not compatible. The good news is that I already tested this and the karaf shell works fine in bndtools. I do not have a complete example ready at the moment. Basically you need to create and index from a pom. Start with the karaf shell.core bundle. It provides support for the new karaf 4 style commands. Then create a bndrun from this index and require the bundle. You might need to add additional bundles to the index. The resolver should help you to find which. Then the more difficult part is to get the shell to work. Luckily I figured this out already: -runproperties: \ felix.cm.loglevel=4,\ felix.fileinstall.log.level=4,\ karaf.systemBundlesStartLevel=0,\ org.ops4j.pax.logging.DefaultServiceLog.level=INFO,\ karaf.startLocalConsole=true,\ felix.fileinstall.dir=./etc,\ karaf.local.roles='admin,manager,viewer,systembundles',\ felix.fileinstall.noInitialDelay=true The core is karaf.startLocalConsole and karaf.local.roles. Without these the karaf shell will not start up. Christian On 09.02.2017 03:09, G.

In my BndTools, I want to be able to see whether my datasources are available using the command 'jdbc:ds-list', the same way I successfully did in karaf. So, I determined the list of bundles installed with the karaf 'jdbc' feature and added all those bundles to my execution requirement in my bndrun (from a local index I built with the bnd index plugin). However, I am not able to get the 'jdbc' commands (jdbc:ds-list does not work and 'help' does not show the 'jdbc' commands). Am I missing something? Aren't the commands built in standard way in OSGi and therefore usable seamlessly inside any framework?

Re: PAX JDBC HikariCP broken in 1.0.0
The build seems to work again ... at least for the most part.
Currently it fails during deployment to the snapshot repo but I think
this is more a problem on the jenkins server.

Re: Release of pax jdbc 1.0.0 is staged now
I found another issue. If you configure a DataSource with pooling but no XA like this: osgi.jdbc.driver.name=H2 url=jdbc:h2:mem:test dataSourceName=person pool=dbcp2 and then add the pooling support as well as transaction support: feature:repo-add pax-jdbc 1.0.0 feature:install transaction pax-jdbc-config pax-jdbc-pool-dbcp2 pax-jdbc-h2 Then you get two DataSources. The reason is that the dbcp2 pooling creates two PoolingDataSourceFactory services. One with xa=true and one without the xa attribute. For just pooling we search for (pool=dbcp2) so we get two services and install two DataSources. What do you think? Should I redo the release? The artifacts are not yet pushed.

Re: Release of pax jdbc 1.0.0 is staged now
I have done some tests on karaf 4.1.0-SNAPSHOT creating a H2 DataSource from config with dbcp2 pooling and optionally xa support. It works fine but I spotted some small issues: 1. If the TransactionManager or pax-jdbc-pool-dbcp2 is missing then the log shows: Tracking pooling support with filter (&(objectClass=org.ops4j.pax.jdbc.pool.common.PooledDataSourceFactory)(pool=dbcp2)(xa=true)) It is a little bit hard to interpret that this means either the pax-jdbc-pool-dbcp2 feature or the transaction feature is missing. I have added this to the Documentation. It would be great if we can improve the logging. 2. If the DataSource is created correctly then there are 3 identical lines in the log: Found DataSourceFactory. Creating DataSource my It seems that we hit the logging 3 times for some reason. There is only one DSF service and only one PooledDataSourceFactory service. So I have no idea why this happens. In any case there is only one DataSource registered. So it does not seem to be a severe error.

Re: JDBC pooling not working with pax-jdbc 0.10.0.SNAPSHOT
I just checked the mysql driver. It does not support a DataSourceFactory
itself. So you will need the adapter from pax jdbc.
You can simply check how pax-jdbc-config does it.
See
https://github.com/ops4j/org.ops4j.pax.jdbc/blob/master/pax-jdbc-config/src/main/java/org/ops4j/pax/jdbc/config/impl/DataSourceFactoryTracker.java
https://github.com/ops4j/org.ops4j.pax.jdbc/blob/master/pax-jdbc-config/src/main/java/org/ops4j/pax/jdbc/config/impl/DataSourceRegistration.java
The most complicated part in pax-jdbc-config is tracking the
TransactionManager, PooledDataSourceFactory and DataSourceFactory.
As you do not have to make your code universal you can make this easier
by using DS and just injecting the named services you need.
If you need it universal then the fastest way is to just copy and change
pax-jdbc-config.

If I could ask something else: are you aware of any example
programmatic creation of the data source you can point me to? We have
our own library of credential resolution, and I'd like, instead of

can create the data source programatically.

Hi,
In Karaf 4.0.8, I did the following feature install:
/*feature:install transaction jndi
pax-jdbc-h2/0.10.0.SNAPSHOTpax-jdbc-config/0.10.0.SNAPSHOT
pax-jdbc-pool-dbcp2/0.10.0.SNAPSHOT*/
A 'service:list DataSourceFactory' shows the H2 service but
not the pooled/XA version of it. I have the same problem when
I also install 'pax-jdbc-pool-aries' feature.
The reason I want 0.10.0.SNAPSHOT is that I need to use the
JTDS drivers for some of my SQL Server connections.
What I tried next is to uninstall version 0.10.0.SNAPSHOT of
the pax-jdbc features and install version 0.9.0 instead. The
pooled/AX services now show up for H2. Next, I installed
pax-jdbc-jtds version 0.10.0.SNAPSHOT (version 0.9.0 does not
exist). I also got the pooled/XA services for jtds this way.
However, I have these 2 features started:
pax-jdbc-spec 0.10.0.SNAPSHO
pax-jdbc-spec 0.9.0
I am not sure whether my solution is ok and whether there
would be a problem having different version of pax-jdbc-spec
running.
Any suggestions?
Thanks!!

Re: Documentation for the new pooling and XA support in pax-jdbc on master
I fully agree.. The even bigger problem is that people do not really
understand what recoverable means at all.
Until recently my understanding was that without recovery all running
transactions would simply be rolled back in case of a crash .. but this
does not seem to be the case.
Luckily I met Tim Ward at eclipsecon last week and he explained to me
what happens with and without recovery but we need to spread the word
more about this.
So if I understood correctly the problem without recovery is that if the
server crashes while one resource in an XA transaction is already
committed and the other is not then
it will remain in this way.
So I think some people can live with it as it is a rare case but it is
really important to make people aware of the risk so they can make an
informed decision.

For example in the old pooling support if you use the pooling and

TransactionManager or the pooling module the
DataSource is simply not created. There is no error in the log as
the config module can not know if the enhanced DSF is just not yet

In the new pooling and XA support there will be a good error in
the log if either the pooling or the TransactionManager are missing.

Re: Adapt PAX-Exam as an OSGI runner?

An alternative you could look into is bndtools with the recent maven integration. See http://bndtools.org/ It allows to define a running system using a backing index and requirements. I used this in CXF DOSGi to create a small example: https://github.com/apache/cxf-dosgi/blob/master/samples/soap/soap.bndrun The runbundles are automatically computed from the index and requirements. Using the Eclipse IDE extension it is quite easy to define and change such running configs. The CXF example above also has a maven plugin that does the build completely automated. The result is a runnable jar that you can start with java -jar. So as was discussed before on this list it would also be quite interesting to go the other way round and use bndtools bndrun files to define a pax exam test run. This is not done yet though.

Bnd can generate the DS xml from annotations but it will need a bnd plugin for DS. I think I tried this at some point and got it working but considered it too complicated for my case.

Re: Pax exam config module for bndtools
It would be great to work together on this. I just talked to Peter Kriens to get some hints about using bndrun files. Simply reading the file is probably not a good idea as even the resolved bundles do not directly give us the jar locations and we do not want to reimplement their indexes. He recommended to create a run and work with the bundle objects it provides. I have done a similar thing in a maven plugin to resolve and export using bndrun files: https://github.com/bndtools/bnd/blob/master/maven/bnd-export-maven-plugin/src/main/java/aQute/bnd/maven/export/plugin/ExportMojo.java So I think it should be possible to get all the informations we need from there. For the other way round I am not sure if it makes much sense. The main advantage of bndrun files for me is that they can be edited with the bndtools editor. The editor has a nice UI for accessing the backing index to simply drag bundles over. The resolve button also provides some nice feedback if something is missing. In pax exam configs the main issue for me is to specify the bundles to install. You first have to add them to the pom and then a second time in the pax exam config. The bndtools UI for bndrun files together with the resolver should eliminate most of this manual work. In the current version of bndtools it is already possible to work with indexes created by maven. See https://github.com/cschneider/osgi-chat/blob/master/packaging/service/service.bndrun The upcoming version will even allow to specify a pom directly as an index. In parallel I am working on providing such pom based indexes for apache projects. This should make it a lot easier to create OSGi assemblies in the future. For example Aries RSA and CXF DOSGi already have these repository poms and so they are really easy to add to your index pom.

New design for pax-jdbc-config and pool for better user experience
Current design of pax-jdbc-config and pool
The DB driver or a pax-jdbc adapter provide a DataSourceFactory service.
This service does not necessarily provide pooling or XA support.
There are several pax-jdbc-pool modules. Each of these tracks the
original DataSourceFactory service and installs a pooling as well as XA
enabled DataSourceFactory serice on top. These delegate to the original
DSF to create the DS and then wrap it with pooling and XA support. the
new DSFs are create with the names -pool and -pool-XA attached.
The config support expects the user to install a config for a
ManagedServiceFactory that refers to the DSF by name or class with the
suffixes attached if pooling and or XA support is desired.
See
https://ops4j1.jira.com/wiki/display/PAXJDBC/Create+DataSource+from+config
https://ops4j1.jira.com/wiki/display/PAXJDBC/Pooling+and+XA+support+for+DataSourceFactory
Problems
A lot of users struggle with the current design as it is a bit unnatural
when learning it and there are lot of things that can go wrong without
good error reporting.
So for example when the original DSF is missing then the enhanced DSF
will just not be created. If the TransactionManager is missing then the
XA enhanced DSF wrapper service is not created.
It is also confusing to have many DSF services if for example the
pax-jdbc native adapter as well as the original driver both install a DSF.
If anything is wrong then the DS service is simply not created. As this
all uses the whiteboard pattern there is no easy way to give direct
feedback as when something is missing it can mean that the setup is
wrong but also that maybe the needed services simply have not yet come up.
Goals
So the goals of a new design are to provide a more natural solution and
also provide good error/warning messages if anything is wrong in the system.
New Design
For the new desgin the main idea is to only have the orignal DSF service
and not create additional ones. The pooling and XA support is provided
by a new service interface that is only used internally in pax-jdbc and
does not have to be visible to the user.
For the configs the idea is to have properties that mark the need for a
pool or XA:
If the property pool is present in the config then it means the user
wants pooling support. If it is not present then the orignal DSF is used.
pool=[dbcp2,aries,narayana]
If the property xa=true is present then the user wants XA support on top
of pooling. XA support without pooling is invalid.
xa=true
The pooling and XA support it implemented in a plugable way by
implementing this interface:
package org.ops4j.pax.jdbc.pool.common;
public interface PooledDataSourceFactory {
DataSource create(DataSourceFactory dsf, Properties config);
}
The impl is published as a service with e.g. pool=aries and xa=true.
Error reporting
The pax-jdbc-config module will detect any DS config and immediately
report that it has detected the config and what it is searching for now.
For example if you give it the config below then it will report that it
searches a DSF with the property |osgi.jdbc.driver.name=H2, |aries
pooling support and a TransactionManager service.
|osgi.jdbc.driver.name=H2|
|databaseName=||test|
|user=sa|
|password=|
|dataSourceName=test2
pool=aries
xa=true
|
|pool.maxTotal=8|
After a timeout it will warn about which of the above is still missing.
||To further improve the experience we could also hint for ways to fix
the problem. Like when you give osgi.jdbc.driver.name=H2 it could report
that you should install the pax-jdbc-h2 feature in karaf,
pax-jdbc-pool-aries if the aries pooling is missing or the transaction
feature if the TransactionManager service is missing. Not sure if we
want to be karaf specific here though.
