Re: Migrating from Karaf 2.4.1 to 4.0.5, JPA problems
Genereally Aries JPA should work with OpenJPA 2.4.1 but I think there is
some bug in karaf 4.0.5.
I just tested again and found that persistence api 2.0 and 2.1 are both
installed. This fails as Aries JPA can only bind to one of these and
will choose the higher version.
As a workaround you should be able to create your own feature copied
from the Aries JPA feature but make sure you install the persistence api
only in version 2.0.
I will try to create a working version of the features for karaf 4.0.6.

I don't really know why the JPA version 2.1
(2.1.0.v201304241213) is being installed. I do not do
this explicitly.
Looking at OpenJPA 2.4.1, it seems to depend on JTA 1.1
not JTA 1.2.
Looked again at my JPA version. I do use JPA 2.0. But I
use version 1.1 of artifact geronimo-jpa_2.0_spec which
caused me to believe I was using JPA 1.1
I'm still kind of confused. It would be thankful if you
could tell me what features (and versions of those
features) I should install in order to use the latest
version (2.4.1) of OpenJPA.

Re: Migrating from Karaf 2.4.1 to 4.0.5, JPA problems
Hmm this could actually explain the problems we see. I always wondered
why karaf insists to install the 2.1 version of the jpa spec bundle but
this explains it.
Luckily this should be easy to solve. Try to install the OSGi jpa spec
bundle:
http://search.maven.org/#artifactdetails%7Corg.osgi%7Corg.osgi.service.jpa%7C1.0.0%7Cjar
It should contain exactly the missing package. I think we are missing
this bundle in the feature. We just did not see it as it is embeded in
the jpa 2.1 spec bundle we use.
You could also try to simply add this bundle to the persistence-api
2.0.0 feature. Maybe then karaf already does the right thing.

Hope you understand this a bit better than me but it does not seem to

Karar 4.0.5. If you have a workaround to try before you get a fix inte
Karaf 4.0.6 I would be grateful.

If multi-location solves your problem and you are on R4.2 the
solution is not to reinvent it for R4.2 or blueprint but to

I think that there are no “blueprint people” other than

I would also suggest studying at least the R6 config
admin spec and understanding multi locations as that
will make it clear that blueprint shouldn’t have
anything explicit to do with bundle locations and that
your concerns about sharing configuration across bundles
have been dealt with in the appropriate spec already.
In addition I suggest studying the DS R6 multiple pid
support as a possible model for what you are interested
in. I don’t think your apparent idea of using pid name
parsing as the way of relating multiple pids is very
scalable or comprehensible.
On the other hand, you could approach this all from a
management agent perspective and have the management
agent merge configuration source data with related
“names" into a single configuration. This would work
with current blueprint cm.
I think that merging data in config admin is an
untenable approach. It certainly wasn’t the approach
adopted for DS, and I would think getting spec support
for it would be difficult.

Re: Properties cfg wish...
> proxies ensure that Camel has what it needs when it runs Unfortunately this is not true. Camel only runs well because the defined start levels start the components before your user bundles. This is a very fragile approach though and totally breaks when not using karaf. The core of the problem is that in camel you access a component by just a String uri. If the component is present at the time the route starts then this will work if not it will break. As the dependency to the component is just a URI there is no way to use static code analysis to make sure all necessary components are present. So I am not sure how to solve this.

When I fire up Fuse with 800 bundles the thought of having to manage start up orders as one more configuration chore is a bit depressing.

Re: Properties cfg wish...
If you only need very generic configs then using a System property is also a good choice. You can not change these at runtime but Aries blueprint can use System properties quite conveniently. Christian On 08.07.2016 14:11, Brad Johnson wrote: David B, The Configurator looks like it is on a good track. I'll have to re-read to grok all the implications. Interestingly this made me think of an interim work around for some of the issues identified in the paper with the way the file based blueprint cfg mechanics work. Currently I associate my cfg files with my bundles and use features to install and rename them. But if those cfg files for a subsystem existed in the same bundle then it would be easy to create a plugin to merge parent->child properties into the final pid.cfg file. Reinstalling the bundle would then trigger a reload on bundles specifying that update strategy. One would still end up with one bundle/one PID cfg in the end bound to the blueprint properties. But to modify something like a common URI for a file location or endpoint could happen in a parent cfg file that is then compiled into the various concrete PID.cfgs, put into the bundle, and then installed into the system (with overwrite = true). Not an ideal way of doing this perhaps but maybe a way to work around the limitations imposed by blueprint's lack of support of multilocations and single PID binding. That could also make creating dev/test/production configuration bundles easier since that could be a settable parameter. -- Christian Schneider http://www.liquid-reality.de Open Source Architect http://www.talend.com
Re: Properties cfg wish...
Can you give some examples of typical config properties that need to be shared between these bundles. Maybe they lead to an idea for a different design. Christian On 08.07.2016 15:09, Brad Johnson wrote: Christian, Thanks for the feedback. I'm actually looking for a bit more robust solution. Just the one small project I'm working on now has 12 business processes with a number of OSGi services that provide cross-cutting concerns. In this case they are service like credit card authorization, refunds, etc. CXF front ends them with REST/SOAP and I use recipientList to route them. But each of those business processes use OSGi services that might call out to banks, PayPal, analytics services, etc. Keeping these nicely segregated in their own bundles makes them very testable for the routing, data transformation to/from canonical form, etc. But configuration management is a bit of a pain because of the PID pinning. I use update strategy reload on the bundles so that configurations can be changed in different environments. Until now I've kept my configuration files in each bundle and pop them out using the features install mechanism. But I'm rethinking that based on these discussions. I don't know if the Maven properties plugin would do what I'm thinking about but it might be a platform to develop such a plugin. In this case I'd have a separate configuration bundle with my PID cfgs in them and N levels of parent cfg files. The properties would just be rolled up and written out into PID specific cfg files. If I define a port or directory in a parent then all the children would inherit or override that property. That would permit the use of profiles for dev, test and production as well. Modifying any of the cfg files and then putting that through Jenkins would result in a nice configuration bundle that once reinstalled would trigger a reload.

Re: Migrating from Karaf 2.4.1 to 4.0.5, JPA problems
You config looks good. I think it would be great to update the docs. Can you edit this yourself in the pax-jdbc wiki? If you do not have wiki access you can ask for it on the ops4j mailing list. The error you get: Auto-commit can not be set while enrolled in a transaction" might be an issue in dbcp2. I thought it would be solved already. You can try to report it at openjpa and dbcp2. If you do not use the newest pax-jdbc version then you could also try that. Unfortunately I was not able to find the issue at pax-jdbc or dbcp2.

As far as I undetrstood you use the non-jta-datasource if you use local
transactions instead of jta.
I have no clue though why there are these two elements. It is very well
posssible of course that I missunderstood something in the spec.
Did you find any explanation in the jpa specs about this?

Re: Migrating from Karaf 2.4.1 to 4.0.5, JPA problems
I looked it up in the jpa spec (see below). So I think I interpreted
this correctly.
Christian
8.2.1.2 transaction-type
The transaction-type attribute is used to specify whether the entity
managers provided by the
entity manager factory for the persistence unit must be JTA entity
managers or resource-local entity
managers. The value of this element is JTA or RESOURCE_LOCAL. A
transaction-type of JTA
assumes that a JTA data source will be provided—either as specified by
the jta-data-source ele-
ment or provided by the container. In general, in Java EE environments,
a transaction-type of
RESOURCE_LOCAL assumes that a non-JTA datasource will be provided. In a
Java EE environment, if
this element is not specified, the default is JTA. In a Java SE
environment, if this element is not speci-
fied, the default is RESOURCE_LOCAL.

It is a bit of a problem of course. It was a convenient way to create the database on first usage that now does not seem to work.

Really complicates our installations procedures... BTW, how come it works if I use the derby-pool datasource?

The CDI annotations added in to pax-cdi for using OSGi services right from a bundle using only CDI and not a combination of CDI/DS is a very big deal I think.

Re: DS vs Blueprint
It simply uses the existing HttpService so it will not start a new
instance. You can even use the felix http service bundle instead. CXF will
not care.
I typically use this variant as it only needs one port for all services
which makes it easier to manage.

Re: DS vs Blueprint
If you use ds then you can always override any service property using a
config. This allows to dynamically change the address at runtime.

I guess we can add this case to the proxy.
Can you help by creating an issue on Aries jira and later test the

Alternatively if you want you can also try to fix it yourself and

Re: jax-rs bootstrap of RFC-217
I would prefer maven as I am more familiar with it. If you choose gradle make sure you take some extra effort to explain how people do the build and also how to setup eclipse to work with the code. In any case I propose to use a separate git repo for the new project from the start (Like Aries RSA). I would also rather not use the old parent in the main aries repo and rather build a parent like I did in the Aries RSA project. The parent there might be lacking some few features but it makes the whole project so much simpler. See https://github.com/apache/aries-rsa I also propose to do the OSGi configs in bnd.bnd files from the start.

Re: JPA Container - Unexpected EntityManagerFactory Service Registration
Yes you are right. The mysql bundle does not create the DSF. So you
still need pax-jdbc-mysql.

I think the mysql driver indeed registers the DSF. You might need to
provide the bundle for the DataSourceFactory api though. Can you try
that?
The DataSourceFactory is exported by the enterprise bundle (Ugh, I

I can see the reasoning. That is confusing though. I thought that
the MySQL driver now registered the DSF, just like the h2 bundle,

Hi,
I am seeing a strange (wildly confusing) service
registration when using the Aries JPA Container with
Equinox. Not sure where the problem is, so I figured I
start here.
When the DataSource and the PersistenceProvider are
available the container registers the
EntityMangerFactory* services. However, the
EntityManagerFactoryBuilder Service shows up as being
registered by the container bundle while the
EntityMangerFactory Services shows up as being
registered by the bundle that provides the persistence
unit.

Re: Export Control ECCN /CCATS information Request
Aries is more like an umbrella project for several independent libraries. See the list of modules at http://aries.apache.org/. As none of these modules can run by itself I am not sure if they can be classified as a product at all. About an existing classification. This might be something for our committers from IBM.

Re: Updating entities with Aries JPA in Declarative Services
Transaction type JTA means that you need a JTA transaction instead of a
local transaction on the em.
In both cases it is necessary to be in a transaction when you do changes
to the database.
The JPATemplate allows to transparently begin and commit the
transaction. It also demarcates the lifecycle of the em. So outside the
outermost JPATemplate execution the em is closed and your entities are
detached.
Your code without a transaction might work but rather as a side effect
of persistence manager caching. For example hibernate does not directly
write to the database when you change properties.
So simply changing the properties might work outside the transaction.
Still I would not recommend it as you never know when hibernate decides
to write to the db.

Hallo,
I have got a question regarding updates of JPA entities using Aries JPA with

Let's assume we have the Task entity from the example here:
https://github.com/apache/aries/blob/trunk/jpa/examples/tasklist-model/src/main/java/org/apache/aries/jpa/example/tasklist/model/Task.java
When e.g. the fields "title" and "description" must be updated, is it mandatory
to do it via JpaTemplate within a transaction like this:
jpa.tx(em -> {
task.setDescription("New description");
task.setTitle("New title");
em.flush();
});
or can safely be done without any transaction like this:
task.setDescription("New description");
task.setTitle("New title");
I would say, it can be done directly without any transactions on application-level because
transaction-type is "JTA" and not "RESOURCE_LOCAL".

For now this is a good pattern. I plan to add a pure TransactionTemplate

Alternatively you can inject a UserTransaction and use it to create the

Re: Re: Consistent entity updates without exposing JpaTemplate
Aries transaction control is an option but you have to completely switch
then.
Unfortunately tx control is not compatible to JPATemplate.

Re: Use Existing Zookeeper Instance for RSA / Multiple RSA Instances Per Machine
Both cases should already work with the echotcp example. https://github.com/apache/aries-rsa/tree/master/examples/echotcp In the readme we start two karaf instances. The first instance starts a zookeeper server while the second instance only connects to it. In karaf you achieve this by installing the aries-rsa-discovery-zookeeper-server feature if you want a server and the aries-rsa-discovery-zookeeper if you only want a client. If you look at the feature file you see that the diference between the two features is indeed just the config file https://github.com/apache/aries-rsa/blob/master/features/src/main/resources/features.xml So if zookeeper server is created then you seem to have a config for it in config admin. Normally it is sufficient to remove the config file to remove the config .. but it does not work in all cases. For example if you remove the config while karaf is stopped then it will still be present in config admin. So I suggest to use the config commands to check if a config exists and to remove it. For running two instances on the same machine you indeed need to tweak some configs. It depends on which transports you use. Can you give some more details? For example for the tcp transport you need to provide one unique port per service: https://github.com/apache/aries-rsa/blob/master/examples/echotcp/service/src/main/java/org/apache/aries/rsa/examples/echotcp/service/EchoServiceImpl.java Christian 2017-09-29 18:45 GMT+02:00 Jonathan knez : > I am successfully using Aries RSA to provide an OSGi service on one host > and consume it on other hosts.

Re: Aries-RSA - Question regarding bundle start order
Can you do a quick check if the problem also happens with the tcp transport? I think it should be independent of fastbin. In general remote services should be independent of the start order of the bundles. So this might be a bug in TopoligyManager or in the zookeeper discovery.

[HEADS UP] Removal of DiscoveryPlugin in Aries RSA zookeeper discovery
I am currently preparing Aries RSA for the OSGi R7 tck tests. During this work I am also looking into cleaning up old stuff. I found that the DiscoveryPlugin facility in the zookeeper discovery does not seem to work at all. The properties are changed but never used in writing the endpoint to zookeeper.

Re: Aries RSA: securing exported services with ExportPolicy
Any webservice exported using blueprint is accessible from remote. You will
only not see it as a rsa remote service.
What I meant is. Can you export your service using rsa but without an
Export policy if you add the interceptor as a service property? I am not
sure if this kind of interceptors work with the current cxf dosgi versions.
In general the recommended practice for securing services is using a CXF
feature and refer to it as an intent. For example the new CXF logging
feature registers itself as an intent.
https://github.com/apache/cxf/blob/master/rt/features/logging/src/main/java/org/apache/cxf/ext/logging/osgi/Activator.java#L89-L90
The rest example readme shows how to add such an intent to your service:
https://github.com/apache/cxf-dosgi/blob/59e432afabb2a8f6a812b2a8f12cda68f4bfa775/samples/rest/README.md#add-logging-intent
(Basically you simply add a service property "service.exported.intents"
with your intent name as value).
This way you could create a feature that adds the security interceptors and
export it with intent name "mysecurity" and then add the service property
above to all services that should be secured.
The ExportPolicy is only needed if you want to add this property
transparently to your services without touching them.

Re: Aries RSA: securing exported services with ExportPolicy
Hi Christian,
the JAASAuthenticationFeature only does authentication.
When deployed in karaf the default realm should be fine.
For authorisation see e.g the SimpleAuthorizingInterceptor.

In plain CXF you can specify the endpoint address which can include an IP
Adress but there are no placeholders.
What do you try to achieve with a specific IP?

Re: Aries RSA: securing exported services with ExportPolicy
This is not necessary. In both cases (cxf blueprint namespace as well as
rsa) you can use a path like "/myservice".
This uses the servlet transport. In karaf it is provided by pax web.

Re: Coordination between spring JtaTransactionManager and Aries JPA
I also had the problem of combining jpa and camel transactions a while ago and created an example and documentation for XA setup. See: https://github.com/Talend/tesb-rt-se/blob/master/examples/tesb/ebook/xa-docs.md https://github.com/Talend/tesb-rt-se/tree/master/examples/tesb/ebook Camel route: https://github.com/Talend/tesb-rt-se/blob/master/examples/tesb/ebook/ebook-importer/src/main/java/org/talend/esb/examples/ebook/importer/ImportRoutes.java The example reads from a xml file, parses each record into a jaxb bean and sends the serialized bean to jms. Then it reads from jms into a bean again and writes into a database using jpa. This second flow coordinates a camel jms transaction and a jpa db transaction using jta. You can find the necessary jta setup in the camel context: https://github.com/Talend/tesb-rt-se/blob/master/examples/tesb/ebook/ebook-connectionfactory/src/main/resources/OSGI-INF/blueprint/blueprint.xml and the connection factory definition: https://github.com/Talend/tesb-rt-se/blob/master/examples/tesb/ebook/ebook-importer/src/main/resources/OSGI-INF/blueprint/blueprint.xml I think what is not mentioned in the example is that you have to setup an xa ready datasource (at least I did not find it) using pax-jdbc. See https://ops4j1.jira.com/wiki/spaces/PAXJDBC/pages/119078914/Pooling+and+XA+support+in+1.0.0 https://ops4j1.jira.com/wiki/spaces/PAXJDBC/pages/61767716/Pooling+and+XA+support+for+DataSourceFactory Cheers Christian Am Mi., 5.

Re: Bundles waiting for JPATemplate service on Apache Karaf startup
I also think this might be related to deleting the bundle cache while the system still runs. If you want a clean startup then you should delete the karaf data dir while the system is stopped. This also deletes the installed karaf features though. So to get your system up automatically you must configure your features as boot features. If you save all your configs in the etc dir then deleting the data dir will still preserve configuration. Christian Am Mi., 19.

The blueprint tutorial on the aries site is quite ancient. You can see my tutorial here: http://liquid-reality.de/Karaf-Tutorial/01/ I also recommend to use declarative services instead of blueprint.

Problem with JPA user bundle not finding EntityManagerFactory. Property org.apache.aries.jpa.proxy.factory=true missing
Hi all, I have a problem with Aries JPA and OpenJPA. My bundle uses container managed persistence. It defines a persistence.xml and it is picked up by the aries jpa container which published a service for the EntitiyManagerFactory. I inject the EntityManager using blueprint like in the Trader example. The problem is that the blueprint integration looks for another OSGi service than the container provides. This is what the bundle searches for: 2012-01-13 09:02:21,001 | INFO | rint Extender: 3 | BlueprintContainerImpl | container.BlueprintContainerImpl 305 | 9 - org.apache.aries.blueprint - 0.3.1 | Bundle db-examplejpa is waiting for dependencies [(&(&(org.apache.aries .jpa.proxy.factory=true)(osgi.unit.name=person))(objectClass=javax.persistence.EntityManagerFactory))] And this is what the bundle provides: db-examplejpa (68) provides: objectClass = javax.persistence.EntityManagerFactory org.apache.aries.jpa.container.managed = true org.apache.aries.jpa.default.unit.name = false osgi.unit.name = person osgi.unit.provider = org.apache.openjpa.persistence.PersistenceProviderImpl osgi.unit.version = 2.1.1 service.id = 216 - So it seem the property "org.apache.aries.jpa.proxy.factory=true" is missing.

Problem using the jmx whiteboard to create a MBean -- MBean class Proxyaaaf7dc3_99e0_4e6d_a856_3c442bfe30ed does not implement DynamicMBean
Hi All,
I started using the aries jmx whiteboard bundle to register mbeans for
Apache Karaf.
When I register the service for the mbean the whiteboard bundle picks up
my mbean but then the following eception occurs:
2012-04-03 16:14:23,601 | ERROR | l Console Thread |

It looks like blueprint creates a proxy of my mbean which then can not
be registered as an mbean.
Any ideas what I can do?
Christian
So my blueprint.xml looks like this:

Hi All,
I started using the aries jmx whiteboard bundle to register mbeans for
Apache Karaf.
When I register the service for the mbean the whiteboard bundle picks
up my mbean but then the following eception occurs:

It looks like blueprint creates a proxy of my mbean which then can not
be registered as an mbean.
Any ideas what I can do?

So my blueprint.xml looks like this:

Re: Question about Blueprint Service and Bundle loading
I don´t think that you can influence this... and honestly I don´t think you should. The clean way of loading impl classes for the service would be to offer two impls of a Factory interface as an OSGi service. So you could define the interfaces at one point and let the Factory service in Bundle1 load the classes from bundle 1 and the Factory service in Bundle2 load those in Bundle2.

Re: Question about Blueprint Service and Bundle loading
I understand what you mean but I think dynamic import is already a bad
thing and loading different classes depending on service impl would only
make it more complex but not really cleaner.
So the question is if your problem could perhaps be solved cleanly with
the current OSGi features.
Can you influence how the bundles 1 and 2 work? If yes then why let the
service consumer create the objects? A factory implemented in bundle 1
and bundle 2 sounds like a much better solution to me. You would then
not even need the dynamic import. Of course I may completely
misunderstand what you try to do.
Can you explain in more details how the bundles 1 and 2 work and what
the client has to do?
Christian
Am 20.04.2012 16:08, schrieb Charles Moulliard:
Bundle 1 and Bundle 2 export correctly the packages. This is simply
the client which is not able to loads the classes according to the
interface name only as we have 2 different implementations. When the
bundle client starts, its classloader has to load the classes from
bundle 1 or bundle 2. As we are using DynamicImport, this is not done
at the starting up of the bundle but when the bean is instantiated by
blueprint. Nevertheless, we have no possibilities today to tell using
DynamicImport that it must loads classes implemented in Bundle 1 or
Bundle 2 depending on info provided in the filter=""/> and the filter. That should be a great improvement of OSGI
+ Blueprint if we could have that. That will allow us to really design
/ use OSGI as a modular platform.

How to implement a factory that creates an object from a blueprint recipe
Hi all,
normally you just use dependency injection to inject an object into
another one. This works as long as you can work with one injected instance.
There are some cases though were you want a fresh object each time that
is created from a blueprint (or similar) definition. One such case in
the karaf code is for the SShServer and SshServerAction. There we
currently want to create and start a new server each time the command is
called. So while I am not sure if this is the best example I think the
need for it is there.
So currently we do the following to create the new object:
SshServer server = (SshServer)
container.getComponentInstance(sshServerId);
So we inject the BlueprintContainer and the component id into the
SshServerAction and then call a container method to create the instance.
This makes the SshServerAction class dependent on blueprint and also
violates the dependency injection principle.
So I wonder if there would be a better way to do it.
If not I have got an idea how to achieve that:
We could create a GenericFactory interface like this:
public interface GenericFactory {
public T create();
}
So the class that wants to create the object would have a property:
private GenericFactory serverFactory;
...
SshServer server = serverFactory.create();
So we would simply have to find a way to inject an implementation of the
GenericFactory interface into the object. We could just use a normal
property definition
and detect that it is a factory and then create a dynamic proxy for the
factory.
Another way would be to use an annotation:
@Inject(ref="sshServer")
private GenericFactory serverFactory;
So what do you think? Would it make sense to add this to aries? Or is it
already possible and I just did not find it?

Re: Some thoughts about Blueprint and MetaType
I also think the metatype support could be improved. What I observed is that I often have to repeat the same defaults in the metatype xml and in blueprint. The reason to have the default values in metatype is to have them for e.g. webconsole. The reason to have the default values in blueprint in the default-properties tag is to make sure my application works when no config is present. I have added some snippets below to show how it looks like. I wonder if we could add some more metatype features to the default-properties tag and then use this meta data to create metatype informations like Dirk suggested. So for example we could add attributes for required and type.

In my eyes the following possibilities would be nice to have: 1.Having a namespace that allows the user to add MetaType information to the blueprint definition XML files. This information could then be published using a MetaTypeProvider. 2.Adding the MetaType information to the Blueprint Annotation API and also publishing them using a MetaTypeProvider Additionally I had a look at the Blueprint Annotation implementation and mentioned that the Blueprint model is generated during runtime.

Re: Dynamic configuration of datasource
This is possible in two ways. You can use the http://www.osgi.org/javadoc/r4v42/org/osgi/service/jdbc/DataSourceFactory.html sepcified in the OSGi spec if your drivers supports it. If not then you can try this tutorial: http://www.liquid-reality.de/x/LYBk Basically the idea is to publish a DataSource as an OSGi service using a separate blueprint file and using the service in your user bundle. This way you can have the filter to reference the OSGi service in a config of your user bundle. So you can switch db types.

Re: Dynamic configuration of datasource
Sounds good. Did you export the DataSource as a service in the db-mysql bundle or how did you connect it to your persistence bundle? The only thing you need to consider is if this works with pooling. For some drivers the DataSources are not poolable. In that case you could use the first option I described and implement the DataSourceFactory yourself.

Differences between blueprint core 1.1.0 binary and source in maven central
I would like to debug into the blueprint core code. So I use m2eclipse which automatically downloads the sources from maven central. There I found that the source code for some classes in blueprint core 1.1.0 seem to be missing. For example in the binary there is "org.apache.aries.blueprint.ComponentDefinitionRegistry" and several other classes in this package. While in the source jar there is only the class "org.apache.aries.blueprint.ExtendedBlueprintContainer". Am I searching at the wrong location, or is the source jar broken?

Why does aries blueprint publish a proxy instead of the real object into the service registry?
I am using blueprint to publish an object to the service registry. The problem is that instead of a service it seems to publish a proxy. So I can not introspect the object. I know that blueprint needs to inject a proxy if you use but why does it also create a proxy when publishing a service. Jean Baptiste showed me some code using ProxyManager to unproxy the object but this is quite ugly and makes me depend on aries proxy. So why is the proxy created and can this be turned off?

Re: Why does aries blueprint publish a proxy instead of the real object into the service registry?
Hi David and Chris, I am not sure if we are talking about the same effect. As I wrote in my original mail I am aware of the proxy that is created when injecting a service using blueprint. It is necessary as blueprint does the inject statically. In contrast to this I am observing a proxy when I export the service. I import the service using a service tracker. So I did not expect to encounter a proxy for this case. Guillaume mentioned the security layer as the source of the proxy. I think this should also not apply. The etc/system.properties contains this: karaf.secured.services = (&(osgi.command.scope=*)(osgi.command.function=*)) So while this should match for the commands it should not match for my case where I simply export an Action without any properties. I will dig a bit more. Christian Am 17.02.2014 20:59, schrieb David Jencks: The proxy is a blueprint thing and as Chris says is there to damp bouncing services. I think the DS technique of binding a replacement service before unbinding the old one is a more appropriate solution to this problem, although it certainly has different effects and produces more bouncing. thanks david jencks -- Christian Schneider http://www.liquid-reality.de Open Source Architect Talend Application Integration Division http://www.talend.com

Re: Aries JTA + EclipseLink
There is no real Aries 1.0.0. Aries consists of a set of bundles that are each versioned independently. So you need to specify which exct set of bundles you used. Honestly it is quite difficult to get the combinations correctly. So I propose you try karaf 3.0.3 and install the aries modules you want from there. This will give you a working set of bundles. About the eclipslink support .. We got itests for it but I personally never tested it manually. I heard though that the newest eclipselink should work without the adapter. About 2).

Using service reference to a service created in the same blueprint context
I got a customer that would like to use a quite exotic construct. They want to
export a service in a blueprint context and import it in the same context.
I do not really recommend this model but they would prefer it to keep their
code generation simple.
They know this is not possible with mandatory services so the used optional
ones.
In a simple case the example below works. If the init method of serviceB calls
serviceA though then we always get a ServiceUnavailableException.
My explanation was that the blueprint context is initialized in these stages:
- create references to services, wait till mandatory ones are present
- wire each bean and call init-method
- export all services
So the reason why it does not work for mandatory services is that the
references are checked before our own services are exported.
The reason why the init-method with call to serviceA does not work is because
the services are exported only after all beans are injected.
So I have two questions:
1. Is my model how blueprint starts up correct?
2. Could Aries blueprint theoretically be changed to export services as soon as
all necessary beans are injected instead of at the end? Or is the startup model
above mandated by the spec?
Best regards

Inject a real blueprint service proxy using a BeanProcessor
In the jpa blueprint extension we are currently injecting a hand built proxy that works similar to a blueprint proxy. There are some disadvantages to this approach though. 1. The code for the proxy is less well tested than the main service proxies blueprint uses. 2. Blueprint does not know about the hand made proxies. Ideally I would like blueprint to go into grace period until e.g an EntityManagerFactory service is present. So is it possible to use the blueprint proxies and their definitions (service recipe?) for annotation based injects too?

Re: Externalize the orm property from the persistence.xml
If you are using a data source then hibernate.connection.driver_class should not be necessary. The other ones are needed. Why do you want to externalize them? Btw. in our tests we have properties for hibernate, eclipselink and openjpa side by side. So we can switch the persistence provider without changing the persistence.xml.

Does all this sound correct so far? So, it's not dbcp2, but it's pooling nonetheless and I can adjust preferences by passing the appropriate bean options to my pax-jdbc service with the 'pool.' prefix which will in-turn send those on to the RecoverableDataSource instance. Sound ok still? And finally, my eclipselink JTA datasource JNDI lookups are formatted with filters for the 'aries.managed' property [1] to ensure that I get the aries auto-enlisting DataSources. So far, this is running my existing code ok with only two changes I had to make: 1. Fixed ARIES-1171, but actually in the Tranql code as I was getting connection errors and didn't see a logical place to fix it from an aries class (using latest aries-transaction-jdbc from SVN). This required bringing all the tranql source into my aries bundle and just removing the external dependency. I didn't like doing that, but since that code hasn't changed in a while and I'm still prototyping all this it was the path of least resistance. 2. Changed RecoverableDataSource to not use empty strings by default for username and password. Which seemed to be similar/related to the above and I posted as ARIES-1376.

I am in the process of refactoring an existing JPA/Eclipselink-based application to introduce Eclipselink's partitioning support for database sharding. My current application runs quite well with pooled jdbc connections via boncep. However, with the sharded model there will be a number of entity types that are Replicated to all shards and, as such, eclipselink will be doing writes that span multiple jdbc connections. Per the eclipselink recommendations for paritioning I would like to introduce JTA in order to enforce integrity across commits that hit multiple partitions. It seems like the ops4j-pax-jdbc bundles are designed to support XA/JTA and it seems like there is a lot of XA support in the various aries bundles (aries.transaction. and aries.jpa.). However, I'm not sure of what combination of these bundles+configuration will provide what I am after. Since many of these bundles seem to be designed/documented around general JTA usage - like performing a transaction that spans JMS and JDBC - I'm not confident if that model works with my particular use case. To further add to this, I would like for my JDBC connections to be pooled for performance. ops4j-pax-jdbc-pool-dbcp2 seems like a logical choice, but again I'm not sure if it will play nicely with the transaction management features from aries. I think I have a working model of this, but I'm rather new to XA/JTA especially from OSGi so I want to make sure I'm getting this correct. So, I guess my questions are: 1. Can ops4j-pax-jdbc-pool and it's dbcp2 sibling work with aries-jpa/transaction to pool and auto-enlist XADataSources? 2. If not, will ops4j-pax-jdbc-pool-aries work? And if so, can its pooling semantics be configured? E.g. minIdle, maxIdle, etc. 3. If neither of the above works, is there a recommended set of bundles to accomplish pooled XADataSources with eclipselink+JTA?

Re: Bundle set recommendations for JPA+JTA+Eclipselink Partitioning?
Honestly I have no idea why tranql sets the autocommit. I would not
expect that it needs to be tweaked.
I can imagine that dbcp2 does not allow to change autocommit for XA
transactions as the commit should
only be done when the XA transaction commits. Not sure about this either
though.
I propose you ask this on the apache commons list or open an issue for
dbcp2. It definitely seems to be an issue that
can also happen when just configuring dbcp2 manually and then use tranql
on it.

Subject: RE: Bundle set recommendations for JPA+JTA+Eclipselink
Partitioning?
Thanks very much for the references, I will definitely be looking over them.
I was hoping the dbcp2 bundle would allow for the same XA capability, as I
would prefer dbcp2 pooling since it seems fairly analogous to my current
pooling - bonecp. However, I did some testing with dbcp2 and got exceptions
during runtime when code from base datasource wrappers (from tranql maybe)
was attempting to set the auto-commit flag and the DBCP datasource wrapper
class was throwing an exception about setting auto-commit. I can't remember
exactly the code flow but I'll try to test this again and see about getting
a stacktrace. Does any of this sound familiar? Should I be able to simply
replace pax-jdbc-pool-aries with pax-jdbc-pool-dbcp2 in my runtime? Maybe it
was something in my jndi references not getting the aries-managed datasource
services.
As for the blueprint/DS question, I will be largely using DS to inject
app-specific API that gives my code access to the JpaTemplate/EntityManager
classes. I hope to move toward blueprint, but that will be another effort.
Thanks again,

Hi Matthew,
pax-jdbc-pool-dbcp2 as well as pax-jdbc-pool-aries should both be able
to provide XA enlisting poolable DataSources.
Aries JPA and Transaction actually use the above in their integration
tests. So they should work together nicely.
I got two tutorials that both use XA transactions with Aries:
http://liquid-reality.de/display/liquid/2015/06/30/Apache+Karaf+Tutorial+par
t+10+-+Declarative+services
http://liquid-reality.de/display/liquid/2015/03/05/Apache+Karaf+Tutorial+Par

Btw. Do you plan to use blueprint or DS?

Not sure why you hit the problem with dbcp2 and eclipselink. I have some
itests running
with eclipselink and they showed no problems. Will look into what
versions I used exactly.
I am not very familiar with the aries pooling but it should work fine.

Ok, thanks so much for the suggestions.
It is interesting to me that this isn't something someone else has seen

Do you have a recommendation of using the aries pool bundle vs. the dbcp2
one? I'm not set on either one, I just need it to work, have some
tweakability and perform well enough. I had been leaning towards dbcp2 since
it seems like a reasonable, actively developed pool implementation that I
have used elsewhere, but since it doesn't currently work for me I'm fine
using aries if it works and performs.
It seems to me that the aries pooling basically delegates back to the
Geronimo classes, which I would suspect are a decent pool implementation
themselves having originated as part of that project. But I have no
experience with them, so my confidence is low.
Obviously, I'll do some performance tests when all this comes together more,
but recommended best practices or known working bundle combinations are
always a good starting point. I'm still looking through your earlier
references and all the itest stuff to try to piece together a logical bundle
set, but it's slow for me as I am not very familiar with PaxExam.
Thanks,

Honestly I have no idea why tranql sets the autocommit. I would not
expect that it needs to be tweaked.
I can imagine that dbcp2 does not allow to change autocommit for XA
transactions as the commit should
only be done when the XA transaction commits. Not sure about this either
though.
I propose you ask this on the apache commons list or open an issue for
dbcp2. It definitely seems to be an issue that
can also happen when just configuring dbcp2 manually and then use tranql
on it.

[1] is a snippet from the stacktrace I get when using pax-jdbc-pool-dbcp2

ManagedJDBCConnection#localTransactionStart appears to call setAutoCommit
on
the connection class, which the DBCP2 impl short circuits at [2].
This same exact environment seems to run fine with the -aries pool bundle.
I
am running this with a customized transactions-jdbc bundle checked-out
from
SVN. But, the only change I made was the pull in all the tranql source to
fix issues with the two-arg form of getConnection in some of those
classes.
Aside from that it's unchanged and works fine with the -aries pooling
bundle.
Any suggestions are greatly appreciated.

Re: Bundle set recommendations for JPA+JTA+Eclipselink Partitioning?
This is a complicated theme which is difficult to diagnose just from the outside. I guess your problem already occurs when you have only one connection. Can you create a small example at github that shows how you setup your application? Using the non wrapped connections can work if some other layer is doing the enlistment (e.g. eclipselink) but I am not sure. I am still wondering why I do not see the tranql problems in my tests. Christian Am 07.10.2015 um 00:15 schrieb matthew.w.pi...@wellsfargo.com: Once again, thanks very much for the input and sorry for the late response Here's where I am at... I was pushing forward with just using the aries pooling bundle, however it seemed to *not* do what I would normally expect with connections after a query/exception problem. It would leave them in the pool and allow for their reuse by subsequent queries. This would then lead to 'Connection already closed' or 'communication link failure' type messages in subsequent JPA operations unrelated to the previous problem. With this, I tried once again to work with the PAX dbcp2 bundle and ran into the same problems I had before with the tranql classes calling methods on the wrapped connection that DBCP2 did not like. I went so far as to comment some of the parts of the tranql ManagedJDBCConnection class to prevent it calling down into the DBCP2 connection. When this happened, my queries/transactions would continue on but then fail during another method call (like #commit) where the DBCP2 connection would throw an exception complaining about not being able to perform certain operations when participating in a managed transaction. So, it seemed to me like my DBCP2 connections were already XA aware/enlisted (or whatever you call it) and that the higher-level stuff in aries-jdbc/tranql was incompatible with them. So, here is where it gets really interesting... thinking about this problem I wondered if maybe I didn't even need the aries-wrapped datasources. So, I changed my eclipselink/jpa JNDI lookups to be !(aries.managed=true), to hopefully force eclipselink to use the DBCP2 XA datasource services directly. Well, voila... this seems to not only work, but still provide the xa/jta management as well. To test this I created a conflicting entity row in only one of my three eclipselink partitions or 'nodes'. Attempting to persist the corresponding entity in osgi via my jpa classes failed with the expected exception indicating a conflicting row *and* inspecting the database nodes showed that the only node with the row was the original node where it was manually inserted for the test. So, I'm assuming this is an indicator that the XA stuff ran as expected and prevented the insert from propagating to other nodes because the coordinated transaction was rolled back. So, my question is - does this setup make sense? To have the aries transaction manager/bundles in-place but not actually use the aries-managed datasources? Perhaps there are facilities in the pax dbcp2 pool bundle that does the auto-enlistment already? Perhaps I have no idea what I am talking about? Any guidance is greatly appreciated.

Hi Mihael,
I do not see any calls to txLogService in this snippet. Is it called in

If yes then the question is how coordinationFilter is instantiated and
how the txLogService is injected into it.

Hi Mihael,
difficult to say without the actual source.
The problem occurs when the coordination ends. So maybe this
happens in a different thread.
See
https://osgi.org/javadoc/r5/enterprise/org/osgi/service/coordinator/Participant.html#ended%28org.osgi.service.coordinator.Coordination%29
"Participants are required to be thread safe as notification can
be made on any thread. "
Can you paste the relevant code snippets of
SalesProspectResource.update?
It might also help to update to the new Aries JPA 2.2.0 version.
(Would be a bigger switch though).
