Re: How to install bundle Offline

[Miroslav Beranič]

I do it in production like had Christian described -- as production is
"final" server, there are few servers before it - that have internet
connection, so just rsync it for there to the production server once the
"local" Maven repo is updated.

But based on this thread, I will look into how to build a kar package, I
did not put much effort into any other way as this works for me quite OK.
Or even a Cave, but all this looks too complicated.

Kind Regards,
Miroslav

Re: Karaf SSH invalid encoding

[Miroslav Beranič]

Hi all,

I have the same issue on Apache Karaf 4.2.2 ( commit
da7ae8f76f2db1347200ff6bb4760e4ecbb1b454 ), I get/see ??? chars ( 95% of
the times ) when I redeploy application.

Interesting thing is, this is on one instance only running RHEL 7.5.
Intermediate server environment ( beta server ).

At this time, I solve this with server ( OS ) restart.

But if someone has any other observation or hints to fix - I would be glad
to update :)

Kind Regards,
Miroslav

Re: No URL is defined for schema http://www.springframework.org/schema/osgi.

[Miroslav Beranič]

Hi JB,

if I understood correct, I've looked up, how to install features at boot
time. Is this what you were saying?

So, what I did was: updated etc/org.apache.karaf.features.repos.cfg ( not
really related, but added by feature file here ), and updated
etc/org.apache.karaf.features.cfg to install cxf ( added at the end of
featuresBoot property ):
cxf/3.2.6, \
cxf-jaxrs-cdi/3.2.6

after Karaf startup I can see the CXF with all the dependencies was
installed. But.

When I installed the JPA/Hibernate feature ( part of my project ), I get
following error:

.
.
.

07:40:50.588 INFO [features-3-thread-1]

.
.
.

So now not even JPA/Hibernate is not working any more. I must be doing
something wrong.

I guess "java.lang.NoSuchMethodError" is saying I did not compile class
with the same dependency JAR as I use it in the runtime?


Well, this does not look good. Darn.

Miroslav

[Miroslav Beranič]

Hi all,

not quite done yet.

So new day, new problems. After another round of try/error -- it worked,
and did not work next day.

Even "one xml deploy" bundle was not working. Now, I am more focused into
the CXF project.

I am quite sure, this "works today, does not work tomorrow" is due to
bundle deploy order. I've found out, that there are multiple Xerces
instances flying around. I had one, for some legacy SOAP client generated
from WSDL using Axis 1.4.

It had Xerces, after a lot of redeploys I've figured out that when Xerces
bundle is deployed Karaf is not able to resolve/deploy bundle with Spring
XML configuration.

I am getting
"org.osgi.service.blueprint.container.ComponentDefinitionException:
Unsupported node namespace:" ( notice empty namespace ). When I do
uninstall of the Xerces bundle -- and restart Spring XML configuration
bundle, it works. Repeat Xerces bundle install, Spring XML configuration
bundle fails to load.

When cxf feature is installed bundle:
313 │ Active   │  30 │ 2.11.0.1   │
org.apache.servicemix.bundles.xerces
is installed. I've exported bundles for the feature cxf and JAR file name
is: org.apache.servicemix.bundles.xerces-2.11.0_1.jar

This is also in line with my first voodoo , when I was asking if it is
possible that some dependency makes a mess. I would say, this is the "main
problem".

Other issue was with ActiveMQ and Camel, and "class cast exceptions" for
Spring's classes, also some nice pitfalls there ( all solved with correct
bundle deploy order ).

What I've notices is - order of the feature/bundle loading is the key and
it is not easy. One "innocent" dependency and whole tree of un-wanted
bundles is put into the Karaf.


I would really really like to know, am I doing so much something extra and
no one else has this issues? As all I am doing is loading bundle with
spring xml configuration and SOAP server ( with CXF ) and all stops
working. It is hard to believe this is "only my problem".

The more likely thing is : I am doing all wrong. Also if this is true, I
would really like to know what? How can it be, that if I load Apache CXF
feature and in another bundle Spring XML Configuration, one "overrides"
XML/XSD namespace resolution. To me this is interesting as I would really
like to know, how is this connected and how this is even possible.


So today's finding is: If you have errors like: No URL is defined for
schema http://www.springframework.org/schema/osgi,
org.osgi.service.blueprint.container.ComponentDefinitionException:
Unsupported node namespace:, go and check if you have Xerces bundle
installed. If so, try to uninstall it and restart failed bundle. My guess
is - it will start to work. But what now. How to replace Xerces - it is
like part of every web/xml related project. I have no answer for this.

I've checked CXF source code, and noticed that Spring bundles and versions
are not in sync ( version part of the Karaf - referencing CXF Karaf
repository ) ... so I would suspect this will be another land mine I will
blindly step on.

But

when things are working, when Karaf is able to load ( over Aries ) bundle
with Spring XML configuration -- it works really well and it is really easy
to make it work. That is one of the biggest frustration, as it is such a
nice platform, but one wrong JAR and all stops working ...


Kind Regards,
Miroslav

Re: Pax JMS - ConcurrentModificationException

[Miroslav Beranič]

Hi all,

it seems PAX JMS version 1.0.2 has concurrency problems. I am getting :

karaf@root()> feature:install -r framework-demo

As noted before, I've moved back to "stock" 1.0.2-SNAPSHOT PAX JMS Config
bundle and getting error.

I guess I will move to changed version, with use of ConcurrentHashMap.

Kind Regards,
Miroslav

( notice the "empty" namespace ... )


After all the strange things done, to make it work again, I've started
vanilla project ... and it worked. As expected. Simple as putting one xml
inside bundle class path /META-INF/spring/context.xml.

So, the fun part was -- I "wanted to clean up" config files and I moved XML
files to /META-INF/mm/spring/*.xml and include/import them from context.xml.

And this was the issue. It turned out, Blueprint/Spring support will fly
out of the window, when http://www.springframework.org/schema/osgi is used
in a XML file being referenced / included / imported.

So to fix my issue, I have all the Spring XML files ( that have
http://www.springframework.org/schema/osgi namespace ) stored inside folder
/META-INF/spring/ and all other Spring-only namespaced files in other
locations.

Did not have the time to look over the source code why is this so, but to
me, this is strange implementation. This is also not "pointed out" in the
documentation or so, so ... fun fun fun. Took me days too long to figure
this out.


Kind Regards,
Miroslav

[Miroslav Beranič]

Hi both,

I thought I wrote too much and lost focus.

So, I already use spring-legacy repository, and I get spring-* 4.3.x. I
already had all this working. I do not use spring-dm feature ( I see it is
available, version 1.2.1, spring-dm and spring-dm-web, did not even notice
it before ).

I am using aries-blueprint-spring from Karaf's repository.

aries-blueprint
spring

mvn:org.apache.aries.blueprint/org.apache.aries.blueprint.spring/${aries.blueprint.spring.version}

mvn:org.apache.aries.blueprint/org.apache.aries.blueprint.spring.extender/${aries.blueprint.spring.extender.version}


First I install Spring 4.3 from spring-legacy, next I install
aries-blueprint-spring ( as if not in this order, Spring 5.0.x is installed
).

I've read some messages in this mailing list ( last I found was in August

So, up until today ( when I was doing clean environment setup ) I was able
to use define Spring Beans using XML ( as I am porting application, this is
like top feature ), but now - out of the blue, I've started to get errors

So, has something changed about Spring ( Spring DM ) from Karaf's point? I
went over GIT commits ( for Karaf 4.2.2, last few weeks ), but did not find
anything regarding Spring. I am using Spring 4.3.x ( from Karaf features ).

I have spring-beans.xml inside /META-INF/spring/ folder, and I used
http://www.springframework.org/schema/osgi namespace to "import"
osgi:reference -- and this all worked like a charm.

Now I get this error and no way to find any solution. I "kind of" gave up (
as I read JB's comments - why not use ( only ) Blueprint ), so I gave it a
try. But than I was starting getting even more strange errors,
for example Blueprint failed to set property defined in parent class, or
create instance that takes Map as input into class constructor - as I
failed to find matching property descriptor or class constructor.

Than I went back to original question ... what has changed, that
http://www.springframework.org/schema/osgi has stopped working ( as far as
I know, spring-dm is even older ( based on the mailing messages I've read )
),
so I've uses aries-blueprint-spring.

What am I missing?

Kind Regards,
Miroslav

Pax JMS - ConcurrentModificationException

[Miroslav Beranič]

Hi all,

I was getting ( sometimes ) ConcurrentModificationException when using PAX
JMS ( 1.0.2 ). It turned out to be synchronization fail in
ConnectionFactoryConfigManager. I've made a fix by replace HashMap with
ConcurrentHashMap ( and removed synchronized methods ).

I write here, as I think Karaf is main user base of the PAX JMS library.

Any comment is welcome. Fix is located at:

https://github.com/ops4j/org.ops4j.pax.jms/pull/15

P.S: I've also updated the dependencies ( in my local branch, not part of
the pull request ) - something to have in mind when/if doing local build (
working with Karaf 4.2.2 ).

Kind Regards,
Miroslav

Karaf Configuration Update

[Miroslav Beranič]

Hi all,

I would like to hook into configuration change made in etc/* file. I put
configuration file there and when I change it, I see in Karaf's log the
change was picked up and also file was rewritten.

But, how is this hooked in from the Java class ?


I manual I've only found:
Dynamic Configuration: Apache Karaf provides a set of commands focused on
managing its own configuration. All configuration files are centralized in
the etc folder. Any change in a configuration file is noticed and reloaded.

Back at the scheduler I've seen this:
@Managed("org.apache.karaf.scheduler.quartz")
and implements org.osgi.service.cm.ManagedService

That has method void updated(Dictionary var1) throws
ConfigurationException;

this is great, but this method is not called.

Is there any example/code I can look at at take as an starting point?


Kind Regards,
Miroslav

Re: Bundle context - from inside POJO

[Miroslav Beranič]

JB,

for top of my head - Quartz is passed only QuartzJob class, that gets
created "when needed".
Meaning - I can not pass any non-serializable data/object to the Job - as (
in my case ) Jobs are persistent in Oracle and scheduled/started at later
time - in few minutes or few day, weeks, months ...
In some cases also Karaf is restarted in between ( from the time Job was
created and before it job is scheduled/started )

So usecase is: Quartz Job is created and scheduled ( meaning written to
Oracle ) , due to time span or SW/HW failure Karaf is restarted - when
times comes to start/schedule Quartz Job -- the environment is ( in most
cases ) different in a way, I can not relay on any passed in object.

I imagine also when running on distributed environment it would be a
problem? ( I did not come to this at this point -- one more milestone ahead
).


Thanks for the support (y)

Kind Regards,
Miroslav

Bundle context - from inside POJO

[Miroslav Beranič]

Hi all,

some junior question, but would like to make it correct way.

Is it possible and if it is, how - to get access to BundleContext ( and
other OSGi environment ) from some plain Java object ?

for example

there is an Activator or a Compontent ( class with annotation @Component )
that has code like:

MyClass inst = new MyClass();
inst.doSomeAction();

How would it be possible to get access to BundleContext from inside of the
method doSomeAction() ?

( this is related to my Scheduler work - as I would need access to
BundleContext from inside of a Quartz job, job is executed later on some
day - and even Karaf restart can happen  )


Kind Regards,
Miroslav

Apache Karaf 4.2.2 ( 4.2.x ) Quartz support, with JDBC Persistence and C3P0 JDBC pool

[Miroslav Beranič]

rm. I started to cry again. I did not test features, before I
pushed for the migration. There is no way back, so what can be done now
here.

Let's see.

I basically "re-wrote" Scheduler service in Karaf. What I did:

1.) Make sure Job data has only Serializable data -
- ScheduleOptions was made Serializable, with addition to move Trigger
creation from InternalScheduleOptions's constructor to method compile().
- getJobs() method from Scheduler interface returns String names and not
Objects
- Updated QuartzJobExecutor to remove non-serializable items from
JobDataMap storage

2.)
- Added custom StdScheduler and StdSchedulerFactory classes, to implemented
changes
- Added SchedulerStorage as support for "backward compatibility" and "short
lived" jobs. This is not good place to use it.

3.)
- Updated Scheduler Shell commands to use changed Scheduler API ( job names
are as keys )

Patch file is in this email attachements, I've also pushed changes to my
Github repository, with only this changes:

https://github.com/mibesis/apache-karaf/tree/karaf-4.2.2-quartz-jdbc


Anyone that is willing to use it -- please do, I would only ask Karf core
development team to "make sure" Quartz Job data is always fill with
Serializable data, as this makes all the difference and there is no need
for method getJobs() from Sheculer to return
Map as it can not make data Serializable -- to
return Map is OK, as all API calls are made over
keys, names, etc.

I need few days, to come over this and coffee cups, it is Friday now, so I
guess I will grab some cold drink ... it was big learing experiance for me,
to make this work.

So this is my first patch file, if there is something else needed or I can
support in someway, let me know. ( I know SchedulerStorage is not perfect
solution, but again: it works for me ; but I agree, this can be made better
)


I know I do not say it much ( ever ) -- Apache Karaf is really great
platform, it is just that I send email, when I have problems :D ...

Kind Regards,
Miroslav

Re: Karaf 4.2.1, 4.2.2 ( build from Git ) - Feature install blocked - condition race ( ? )

[Miroslav Beranič]

Hi JB,

thanks for the tip. So, another strange thing is:

- when this block occures - feature fail to install, no other feature is
possible to install, even some basic/simple one.

Please see attachment, full log of what I did.
In short ( last few lines ):

.
.
.
Done.
karaf@root()> feature:install -v my-infrastructure-requirements-jms ( this
is same as in previous feature definition )
Adding features: my-infrastructure-requirements-jms/[2.0.0,2.0.0]
^C~ # Fail here - waiting, but no return
karaf@root()> feature:info my-infrastructure-requirements-jms
Feature my-infrastructure-requirements-jms 2.0.0
Feature has no configuration
Feature configuration files:
  /etc/org.apache.servicemix.activemq.service.cfg
Feature depends on:
  aries-blueprint-spring 0.0.0
  shell-compat [4.2.2, 5)
  activemq-broker [5.15.7, 6)
  activemq-cf [5.15.7, 6)
  activemq-blueprint [5.15.7, 6)
  jms [4.2.2, 5)
  camel [2.23.0, 3)
  camel-spring [2.23.0, 3)
  camel-jms [2.23.0, 3)
  camel-blueprint [2.23.0, 3)
  camel-cxf [2.23.0, 3)
  camel-jpa [2.23.0, 3)
  pax-jms-activemq [1.0.2, 2)
Feature contains followed bundles:

mvn:org.apache.servicemix.activemq/org.apache.servicemix.activemq.camel/7.1.0-SNAPSHOT

mvn:org.apache.servicemix.activemq/org.apache.servicemix.activemq.service/7.1.0-SNAPSHOT
Feature has no conditionals.
karaf@root()> feature:install aries-blueprint-spring
^C~ # Fail here - after first waiting and no return, no additional feature
is possible to install
karaf@root()>

So I am able to "block" Karaf from installing additional features with
this, and this is not so nice "feature" to have in Karaf :)  ( to be able
to block feature install )


Kind Regards,
Miroslav

Re: Karaf 4.2.1, 4.2.2 ( build from Git ) - Feature install blocked - condition race ( ? )

[Miroslav Beranič]

HI JB,

this can be, I would have to check for each feature, but as said: when
porting from Karaf 4.0.9 to 4.2.2, I guess this would have to be addressed
more verbose -- some kind of warning message or something.

I will re-create feature file with suggested changes, but I stopped using
dependency/prerequisite attributes, as I found out I ran into different set
of problems.

I had this kind of problems, when setting up JPA datasource - as conumers
complaint to on start on missing datasource - but bundles installed and
started.

It is "strange" when command "feature:install foo" does not return to
terminal and there is no message in log file.

Thanks, kind regards,
Miroslav

Hi all,

an answer to myself and anyone that runs into same issue:

It needs additional shell compatibility feature:

$ feature:install shell-compat


Works now. All solved.

ActiveMQ support

[Miroslav Beranič]

Hi all,

so I moved from ServiceMix 7 ( build from GitHub source repository ) to
Karaf 4.2.1-SNAPSHOT.

I follow Karaf documentation at (
http://karaf.apache.org/manual/latest/#_jms ) where it is described under
section 4.16.6. JMS.

Basic Karaf commnds are ( should be ):

karaf@root()> feature:repo-add activemq
Adding feature url
mvn:org.apache.activemq/activemq-karaf/LATEST/xml/features
karaf@root()> feature:install activemq-broker

I get failure:
Error executing command: Unable to resolve root: missing requirement [root]
osgi.identity; osgi.identity=activemq-broker; type=karaf.feature;
version="[5.15.5,5.15.5]";
filter:="(&(osgi.identity=activemq-broker)(type=karaf.feature)(version>=5.15.5)(version<=5.15.5))"
[caused by: Unable to resolve activemq-broker/5.15.5: missing requirement
[activemq-broker/5.15.5] osgi.identity; osgi.identity=activemq;
type=karaf.feature; version="[5.15.5,5.15.5]" [caused by: Unable to resolve
activemq/5.15.5: missing requirement [activemq/5.15.5] osgi.identity;
osgi.identity=activemq-karaf; type=osgi.bundle; version="[5.15.5,5.15.5]";
resolution:=mandatory [caused by: Unable to resolve activemq-karaf/5.15.5:
missing requirement [activemq-karaf/5.15.5] osgi.wiring.package;
filter:="(&(osgi.wiring.package=org.apache.felix.gogo.commands)(version>=0.16.0)(!(version>=1.0.0)))"]]]

So it says:
Unable to resolve activemq-karaf/5.15.5: missing requirement
[activemq-karaf/5.15.5] osgi.wiring.package;
filter:="(&(osgi.wiring.package=org.apache.felix.gogo.commands)(version>=0.16.0)(!(version>=1.0.0)))"]]]

As I understand it, it is missing Gogo shell commans package. As far as I
know, this was deprecated for quite some time, as I also had to migrate my
commands. But ... eather way, how is it possible to setup ActiveMQ, as it
is described in documentation. I do not see any repository to get old gogo
shell package.

This is second failure, first one was missing Spring version 4, but I know
how to fix it ( when I fixed that issue, I ran into gogo missing package ).

Karaf version 4.2.1-SNAPSHOT, ActiveMQ version 5.15.5, Java version 8.

Kind Regards,
Miroslav

Re: Apache Karaf 4.x JPA - Working example

[Miroslav Beranič]

Hi François,

thank you for in-depth explanation.

By Blueprint XML I mean:

datasource.xml:

http://www.osgi.org/xmlns/blueprint/v1.0.0";
   xmlns:jpa="http://aries.apache.org/xmlns/jpa/v2.0.0";
   xmlns:tx="http://aries.apache.org/xmlns/transactions/v1.2.0";
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
   xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0
https://osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd";>
















I see, I was looking at different feature name, I was referring to this
feature ( that defines datasource ):



osgi.jdbc.driver.class=org.h2.Driver
databaseName=booking;create=true
dataSourceName=booking


osgi.service;objectClass=javax.sql.DataSource;effective:=active;
osgi.jndi.service.name=booking

Re: Apache Karaf 4.x JPA - Working example

[Miroslav Beranič]

Hi,

@Jean-Baptiste Onofré, François: I can confirm, issues is fixed now. I can
get JPA example working. I see output in Karaf Shell.

but :)


What was the fix ( so I can understand what was wrong, for any future case,
other projects ):

I
see 
examples/karaf-jpa-example/karaf-jpa-example-features/src/main/feature/feature.xml
( I guess this is most of the fix )

 
 transaction
 transaction
+jndi
 pax-jdbc-config
 pax-jdbc-config
 pax-jdbc-h2
 pax-jdbc-h2
 pax-jdbc-pool-dbcp2
 pax-jdbc-pool-dbcp2
 jdbc  jdbc
 jpa  jpa
-hibernate
+hibernate
+
+
osgi.service;objectClass=javax.persistence.spi.PersistenceProvider;effective:=active;javax.persistence.provider=org.hibernate.jpa.HibernatePersistenceProvider
+
   

So this three lines:
+
+
osgi.service;objectClass=javax.persistence.spi.PersistenceProvider;effective:=active;javax.persistence.provider=org.hibernate.jpa.HibernatePersistenceProvider
+

I have similar Bundle structure, but I have dedicated Bundle for DataSource
setup/configuration. How do I translate this "Feature DSL" to "Blueprint
DSL" ==> How would this translate into Blueprint XML?

So changes look they make sense but, this is first time I see this to be
defined so explicit. This was my original complaint, as it always looked
like this piece of code was missing ( also in other available online
examples ).

I also guess "effective:=active;" is important ( as I read the "I've
explained it already three times" forum post ) ( FW:
http://karaf.922171.n3.nabble.com/What-does-effective-active-mean-td4047770.html
)

Well, thank you both very much. Saved me tons of headache.

Kind Regards,
Miroslav

[Miroslav Beranič]

Hi,

first I've started Karaf with ./bin/karaf debug, and from Karaf Shell
installed service with wrapper. Rebooted RHEL and logged into Karaf over
ssh.

It worked for me without any problem.

Rgds,
Miroslav

[Miroslav Beranič]

Hi Oleg,

well, I've never installed from here ( I did not even looked before).
Will try it for my self also. In Git repository I used 4.1.x and 4.2.x.

I guess 4.1.x is more "stable" for production. I've just started using 4.2.
I was on 4.0.9 till previous week. I am doing upgrade across nodes.

Miroslav

Re: java.lang.NoClassDefFoundError: org/apache/karaf/specs/locator/OsgiLocator when running as Service on RedHat 7.5

[Miroslav Beranič]

Hi Oleg,

where from did you deployed Karaf? You build it from the source or some
pre-compiled package/distribution?

In general this is saying you are missing JAR ( but I guess you know
already this ).

( I've deployed multiple times - in past week - Karaf on RHEL 7.5 and I had
no such problem - but I was building from the GitHub git repository )

Kind Regards,
Miroslav

This are all the steps described on:

So my question is only: what is not this working? What am I doing wrong -
are there any pre-requirements ?

Apache Karaf 4.x JPA - Working example

[Miroslav Beranič]

Hi,

I've upgraded my environment from ServiceMix 7.1.0-SNAPSHOT ( running Karaf
4.0.9 ) to Karaf 4.1.x ( GitHub ) branch and later on I've experimented
with version 4.2.x.
I was using linked linkes from Karaf home page (
https://karaf.apache.org/documentation.html ) to GitHub Examples - for JPA.

My main task is to get JPA 2 up and running, but I fail to do so.

So on provided examples Github repository:
https://github.com/jbonofre/karaf/tree/DEV_GUIDE/examples/karaf-jpa-example

I've tested with Karaf 4.1.x and 4.2.x and in both version, Examples for
JPA do now work - for me.

For Karaf 4.2.x I've created PasteBin outputs ( please see ):
1.) https://pastebin.com/eJybVNhn
2.) https://pastebin.com/W2UhihdR

In examples, I've noted that there is a reference to Hibernate 6.0.10.Final
- this version is not released yet ( hibernate.org ), so I guess this is a
wrong version, or ? as I see Karaf has build-in support for
Hibernate 5.2.9.Final.

https://github.com/jbonofre/karaf/blob/DEV_GUIDE/examples/karaf-jpa-example/karaf-jpa-example-features/src/main/feature/feature.xml

For Hibernate version I am looking at:
https://github.com/apache/karaf/blob/master/pom.xml
5.2.9.Final

So what I did was:

1.) checked out Karaf 4.1.x from Github
2.) checked out Karaf Examples ( DEV_GUIDE branch from Github )

3.) Build Karaf with Maven: mvn -Pfastinstall and started Karaf with
./bin/karaf debug
4.) Build Karaf Examples ( changed version of Hibernate from 6.0.10.Final
to 5.2.9.Final )

Read instruction from:
https://github.com/jbonofre/karaf/blob/DEV_GUIDE/examples/karaf-jpa-example/README.md

5.) feature:repo-add
mvn:org.apache.karaf.examples/karaf-jpa-example-features/4.2.1-SNAPSHOT/xml
6.) feature:install karaf-jpa-example-datasource
7.) feature:install karaf-jpa-example-provider

Fail:

Error executing command: Unable to resolve root: missing requirement [root]
osgi.identity; osgi.identity=karaf-jpa-example-provider;
type=karaf.feature; version="[4.2.1.SNAPSHOT,4.2.1.SNAPSHOT]";

[caused by: Unable to resolve karaf-jpa-example-provider/4.2.1.SNAPSHOT:

osgi.service; objectClass=javax.persistence.spi.PersistenceProvider;
javax.persistence.provider=org.hibernate.jpa.HibernatePersistenceProvider;
effective:=active]]

I am using Linux x64, Oracle Java 8 172 x64.

What I am doing wrong. I've mixed different version of Hibernate, Karaf,
... and noting. Always some more or less strange error.

Plus there is an issue: what version of maven-bundle-plugin should/must be
used? I've tried 3.01 and 3.2.0. When I use 3.0.1 I have to update
 if I use 3.2.0 I get error that javassist is not resolved:

Error executing command: Unable to resolve root: missing requirement [root]
osgi.identity; osgi.identity=. ... osgi.wiring.package;
filter:="(&(osgi.wiring.package=javassist.util.proxy)(version>=3.22.0)(!(version>=4.0.0)))"]]]



So all in all I can not and did not find and singe point of truth what is
valid example or way of doing JPA 2 with Hibernate. I guess I am doing
something wrong as all examples make it so simple but ... no luck. All I
did is clean ( new computer - virtual ) checkout from git, build and deploy
- and fail.

I would like to migrate existing code using JPA 1 to JPA 2 ( 2.2 ? ) but
... this is difficult task to complete ( this is after one week of pain and
frustration ).

I've done examples from https://github.com/cschneider/Karaf-Tutorial also,
but no luck. More-or-less same problems.


1.) What versions of Maven plugins should I use?
2.) What versions of JPA?
3.) What versions of Hibernate?
4.) What example should I follow ( URL / Git and branch ) ?


This are my top questions.


Kind Regards,
Miroslav
