Arbitrating between multiple bundles that explore a package

2016-02-05 Thread Benson Margulies

My application was happily working using a bundle I built myself to contain
the Snowball package.

org.tartarus.snowball;version=1.0.2,
org.tartarus.snowball.ext;uses:=org.tartarus.snowball;version=1.0.2

Then I added in the ServiceMix lucene-analyzers-common bundle, version
5.2.1.1.

This _also_ exports the snowball packages.

org.tartarus.snowball;uses:=org.apache.lucene.util;version=5.2.1.1,
org.tartarus.snowball.ext;uses:=org.tartarus.snowball;version=5.2.1.1

Now I get NoClassDefFound errors in the code that goes to use snowball.

Is there anything i can configure in Karaf to get around this? At the
moment, my imports don't have a version on them; I'm hoping for a repair
before I can spin a new version of the importing item.

Thanks, it sounds good.

I would prefer to keep "OSGi" out of the picture on the front page.

Thank you for the explanation JB!

I would probably change the wording to something like:

"Karaf is a flexible component container with multiple deployment
options. Focus on your business code and application and Karaf deals
with the rest."

I think getting the word "component" in there is important, or even
"OSGi" (but that might be too technical). The rest is just a
simplification for clarity.

Raman

"Polymorphic container": adapting to your need depending of the
features. For instance, Karaf can be a container for ESB, Big Data,
web application, IoT, etc.
"Dual": because you can run Karaf as standalone, embedded in a
webcontainer, or bootstrapping ("run everywhere") with karaf-boot

Hi all,

as you may have seen that the new Karaf website is now online.

Don't hesitate to create Jira (with website component) if you see some
broken links and rendering issue.

Thanks !

Re: pax-jdbc-pool-aries

2016-02-05 Thread Charlie Mordant

Hi,

Your pool.maxTotal parameter does not exists in Aries-tx, so you have to
remove it from your config file in order to use it. I think that you'll
have access to these parameters (prefixing them by 'pool.'):
https://access.redhat.com/documentation/en-US/Fuse_ESB_Enterprise/7.0/html/EIP_Transactions_Guide/XaTM-ConfigureTM.html

You'll also have to configure these 3 parameters:


pool.username=
pool.password=
pool.name=

Charlie

The root cause has been identified. Felix doesn't like very well that we
set System Properties within Activator

public void init() {
Properties props = new Properties();
props.setProperty("apiman.es.protocol", "http");
...
System.setProperties(props);

Re: Karaf 4.0.2: Problem Eclipselink 2.6.0 with JPA 2.2.0?

2016-02-05 Thread jochenw

An update for Karaf 4.0.4:

Using JPA 1.0.4 with org.apache.aries.jpa.container leads to a problem with
finding the datasources:

org.apache.aries.jpa.container - 1.0.3 | No JNDI services for
jdbc/myXADataSource are available from persistence bundle
mypersistencebundle/0.1.2.SNAPSHOT. The persistence units [] will now be
unregistered.

Switching back to 1.0.2 in the enterprise feature XML solves that.


Using eclipselink 2.6.1 with org.apache.aries.jpa.eclipselink.adapter 2.3.0
leads to the the same problem as with the previous version:

java.lang.NoClassDefFoundError:
org/eclipse/persistence/internal/jpa/rs/metadata/model/Link

Switching back to 2.1.0 in the enterprise feature XML solves that.


Does it make sense to file a Jira for this, or is the JPA 1.x branch sort of
deprecated, and we should switch to 2.x anyways, switching to the annotation
way for defining persistence units?

Best Regards,

Jochen

Hi Jochen

thanks for the update. I think it makes sense to provide multiple 
feature version (stable) and document which one to use depending of the 
use case (annotation, blueprint, etc).


WDYT ?

JPA and transaction issue in Karaf 4.0.4

2016-02-05 Thread Dutertry Nicolas

Hi,

I'm trying to migrate an application working with Karaf 3.0.5 to Karaf 4.0.4.
I ran into a problem with JPA and transaction management so I have created a 
small maven project showing it.
This sample is available on GitHub : 
https://github.com/nicolas-dutertry/test-jpa

The class TestServiceImpl in test-jpa-service has an EntityManager annoted with 
@PersistenceContext(unitname = "test")
The class DeleteManager also has an EntityManager annoted with 
@PersistenceContext(unitname = "test")

The method TestServiceImpl.delete is not transactional and it calls the 
transactional method DeleteManager.delete several times :

public class TestServiceImpl implements TestService {
@PersistenceContext(unitName = "test")
private EntityManager entityManager;

private DeleteManager deleteManager;

...

@Override
public void delete(String... names) {
for (String name : names) {
System.out.println("Deleting " + name);
deleteManager.delete(name);
}
}
}

public class DeleteManager {
@PersistenceContext(unitName = "test")
private EntityManager entityManager;

...

@Transactional
public void delete(String lastName) {
Query query = entityManager.createQuery(
"delete from Person where lastName = :lastName");

query.setParameter("lastName", lastName);
query.executeUpdate();
}
}

To reproduce the problem, compile the sample project with maven:

Re: JPA and transaction issue in Karaf 4.0.4

2016-02-05 Thread Jean-Baptiste Onofré


Hi Nicolas,

thanks for the update and the detailed use case.

Let's take a look.

Regards
JB

Hi,

I’m trying to migrate an application working with Karaf 3.0.5 to Karaf
4.0.4.

I ran into a problem with JPA and transaction management so I have
created a small maven project showing it.

This sample is available on GitHub :
https://github.com/nicolas-dutertry/test-jpa

The class TestServiceImpl in test-jpa-service has an EntityManager
annoted with @PersistenceContext(unitname = "test")

The class DeleteManager also has an EntityManager annoted with
@PersistenceContext(unitname = "test")

The method TestServiceImpl.delete is not transactional and it calls the
transactional method DeleteManager.delete several times :

public class TestServiceImpl implements TestService {

 @PersistenceContext(unitName = "test")

 private EntityManager entityManager;

 private DeleteManager deleteManager;

 …

 @Override

 public void delete(String... names) {

 for (String name : names) {

 System.out.println("Deleting " + name);

 deleteManager.delete(name);

 }

 }

}

public class DeleteManager {

 @PersistenceContext(unitName = "test")

 private EntityManager entityManager;

 …

 @Transactional

 public void delete(String lastName) {

 Query query = entityManager.createQuery(

 "delete from Person where lastName = :lastName");

 query.setParameter("lastName", lastName);

 query.executeUpdate();

 }

}

At runtime it raised a javax.persistence.TransactionRequiredException
during the second call to DeleteManager.delete in the for loop.

To reproduce the problem, compile the sample project with maven:


mvn clean install


Then, launch Karaf 4.0.4 and install the kar:


kar:install mvn:com.dutertry.test.karaf.jpa/test-jpa-kar/1.0.0-SNAPSHOT/kar


Then, create new entries in database:


person:create Smith 25



person:create Green 23


Finally delete them:


person:delete Smith Green


This will output :

Karaf 4.0.4: org.apache.aries.spifly.dynamic.bundle - where is it loaded

2016-02-05 Thread jochenw

Hello,

since Karaf 4.0.4, all bundles are checked for SPI-provider entries by
org.apache.aries.spifly.dynamic.bundle. Since I currently don't need this
(at least in my own bundles), I'd like to switch this off. However, I have
not found the place where the spifly bundle is loaded - in none of the
feature files.

Where can this be switched off? I should I better not do that since some
Karaf bundles depend on it?

Best Regards,

Jochen

Re: Pax Web - Example of security conbstraint mapping

2016-02-05 Thread Achim Nierbeck

ahh you're talking of non war security.
In that case you need to make sure you have your own httpContext which
handles the security for you.
It's in the OSGi spec how this is supposed to work.
We also have some samples for this.

Re: Karaf 4.0.4: org.apache.aries.spifly.dynamic.bundle - where is it loaded

2016-02-05 Thread Jean-Baptiste Onofré


Hi Jochen,

spifly is referenced by pax web feature (pax-jetty exactly), so I guess 
you installed one of the http features (jetty, http, war, webconsole, 
whatever). Correct ?

module/bundle that we will register within the HTTP Jetty Server ?

The screenshot contains a heapdump, not a thread dump.

I think the NPE is a consequence, so we have to find the cause.

A thread dump should help to see locked or parked threads.
