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: Creating an JDBC

[Jean-Baptiste Onofré]

Hi Christian,

I thought we provide a GenericDataSourceFactory taking just a driver (as
we did with the generic datasource when we used blueprint).

I will check and add this if required: it should be easier for our end
users as they should be able to create a generic datasource without code.

Regards
JB

Re: Creating an JDBC

[Christian Schneider]

You need a DataSourceFactory for this to work. As ingres probably does not
offer this you can create your own bundle with a class that implements
DataSourceFactory and returns a DataSource. This class then must be
published as a service with the above property.

Re: Apache Karaf 4.x JPA - Working example

[Jean-Baptiste Onofré]

Hi Miroslav,

we defined the JPA Engine (provider) as a capability in the feature. It
gives the indication about the engine we want to use.

However, this is a workaround as this capability should be provided
directly by the hibernate feature, not the end user feature.

I created KARAF-5850 for the tracking and I will fix that for Karaf 4.2.1.

As said, today, I will create the itests for the examples that will
allow us to test the examples and Karaf as part of our build (and Jenkins).

JB

Re: Creating an JDBC

[Jean-Baptiste Onofré]

Hi,

As a workaround, you can try to use the bundle:dynamic-import command on
Pax JDBC bundles.

I will check later today if it makes sense to enable by default for
generic driver support.

Re: Apache Karaf 4.x JPA - Working example

[François Papon]

Hi Miroslav,

The changes are :

- use the H2 drivers with class declaration
- add jndi feature
- add capabilities for Hibernate Persistence Provider

The provider module emmebed the persistence.xml with the Persistence provider 
declaration inside so it require the Persistence provider.

We have :
- common feature : provide Hibernate Persistence capabilities
- provider feature : require Hibernate Persistence capabilities

About feature xml and blueprint DSL, this not the same. The feature XML is used 
to packaging bundles and bundles/feature  dependencies, the blueprint xml is 
used to manage your services instances and their services usage.

Regards

François

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,

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

[Leschke, Scott]

Hi Oleg,

I’m the person who originally reported the issue that JB is referring to.  In 
my case on Windows, Karaf appears to work fine as well but there is that error 
in the log that only occurs when you start Karaf using the service wrapper.

Regards,
Scott

[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

Maybe it's related to:

https://issues.apache.org/jira/browse/KARAF-5840 (I already have a fix
on a local branch)

The problem only occurs when using the wrapper.

@Oleg/Miroslav: do you use wrapper to start Karaf instead of bin/karaf ?

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

[Oleg Cohen]

Hi Miroslav,

I think I found the issue. You are right a JAR is missing.

I built org.apache.karaf.specs.locator-4.2.0.jar and added it to the boot/lib 
folder and the exception is now gone.

Thank you!

That is a little bit yucky, and does mean that you probably can’t do it without 
code :(. I do think that it would be better to solve it with a 
ServletContextHelper than in the servlet though. See 
https://osgi.org/specification/osgi.cmpn/7.0.0/service.http.whiteboard.html#service.http.whiteboard.servletcontext
 


This would move your mime-type handling and routing out of the servlet, and you 
could put the resource properties on the same component so that the whole thing 
is encapsulated You could force the servlet to require the context by using the 
context selection property (see 
https://osgi.org/specification/osgi.cmpn/7.0.0/service.http.whiteboard.html#service.http.whiteboard.common.properties
 
)
 if you wanted. This separation would be quite a lot cleaner, even if it isn’t 
smaller.

The specification is part of R7, but the implementation will run on R6. There 
should be no issue deploying it on Karaf, assuming that the PAX Web whiteboard 
support has the correct capabilities advertised for the Http Service Whiteboard 
(V 1.0 from R6 is sufficient).

It’s awesome - once you’ve tried using Component Property Annotations and 
Bundle annotations you will never want to go back!

can you try to enable dynamic import for Pax JDBC ?

I will add this natively.

Creating an JDBC

[Paul Spencer]

Karaf 4.2

I am trying to create a JDBC datasource for a DBMS not natively supported by
PAX-JDBC, specifically Ingres.   Below are the commands I am using to
install the Ingres JDBC driver and create the datasource.  Based on the log
files, the creation process is waiting on a service dependency.

karaf@root()> bundle:install wrap:mvn:com.ingres.jdbc/iijdbc/9.2-3.4.10
karaf@root()> jdbc:ds-create -url jdbc:ingres://localhost/dbname -u user -p
password -dc com.ingres.jdbc.IngresDataSource myDS
karaf@root()> log:display

How to I create a JDBC datasource using com.ingres.jdbc.IngresDataSource?

Yes it might be...  There are after all, just two files that needs to be
served: the initial index.html file and the bundle.js file it references
(the react app and everything is needs, CSS, fonts, images etc. are
packed into bundle.js using webpack).

However, there is a bit of special-casing, such as this:
 
https://github.com/steinarb/ukelonn/blob/using-react/ukelonn.bundle/src/main/java/no/priv/bang/ukelonn/impl/UkelonnServlet.java#L48
that needs to match this
 
https://github.com/steinarb/ukelonn/blob/using-react/ukelonn.bundle/src/main/frontend/components/App.js#L30
so that it is actually possible to enter or reload the URLs created by
the react router into a browser and not get 404.

I haven't found any way to achive single point of change for these
values, and react needs to include the servlet context (in this case,
"/ukelonn") while the servlets' URLs, are relative to the servlet
context.

Hm... is this available in some form in OSGi 6 as well?  Or is this OSGi

As I've mentioned elsewhere in this thread I ran into some strange

out yet.

Indeed.

Seems like there is lots of interesting stuff in OSGi 7, so I should
probably get there as soon as possible.

[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

Add descriptors & features to the features-maven-plugin in goal add-features-to-repo

[fbergandi]

Hello there !

My problem is that I have to deploy a kar file in a servicemix wich is in an
offline server.

To do that, I need to put all the needed features in a local repo in the
server to avoid downloading them. I want to use the features-maven-plugin
with the goal add-features-to-repo to acheive that.

The thing is that I need to specify descriptor that matches my feature and
I'm unable to find them. This is my actual config in the pom.xml of my
project :


org.apache.karaf.tooling
features-maven-plugin
${plugin.maven.feature}


add-features-to-repo
generate-resources

add-features-to-repo




mvn:org.ops4j.pax.jdbc/pax-jdbc-features/1.0.1/xml/features

mvn:org.apache.karaf.features/standard/4.0.9/xml/features

mvn:org.apache.karaf.features/enterprise/4.0.9/xml/features

mvn:org.apache.karaf.features/framework/4.0.9/xml/features
 

mvn:org.apache.karaf.features/spring/4.0.9/xml/features


mvn:org.apache.karaf.features/static/4.0.9/xml/features


jndi
pax-jdbc
pax-jdbc-spec
pax-jdbc-oracle
pax-jdbc-config
pax-jdbc-pool-dbcp2
jpa
transaction
jdbc
hibernate

target/features-repo





I can build without errors my project, but when I put the .kar in the deploy
directory of servicemix and change the property
org.ops4j.pax.url.mvn.localRepository to my features-repo in the file
org.ops4j.pax.url.mvn.cfg in etc directory, I get this error :

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

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

[Oleg Cohen]

Greetings,

I have deployed Karaf v4.2.0 into a Linux RH 7.5 server.

When I run Karaf as a service I get the following error in the log multiple 
times:

Re: Examples of using Jersey with pax web whiteboard extender?

[Tim Ward]

Would it not be easier to:

Use the Http Service Whiteboard support for resource serving, rather than 
having the ReactServlet? That’s a big bit of boilerplate for serving some 
static content. It should be much simpler using component 
properties/annotations - see 
https://osgi.org/specification/osgi.cmpn/7.0.0/service.http.whiteboard.html#d0e121459
 

Use the JAX-RS whiteboard to directly register a JAX-RS resource, avoiding the 
need to teach people about launching Jersey (something that they probably care 
very little about). It’s really very simple to do - see 
https://osgi.org/specification/osgi.cmpn/7.0.0/service.jaxrs.html#service.jaxrs.resource.services
 

 

Using those features should be able to make the example more concise and 
compelling.

Best Regards,

Tim

What it says is ( how I understand it ) : Hibernate 6.0.10.Final is missing
( as I said in first email ) This version of Hibernate does not exists - it
is not release yet, as the latest version released is 5.3.2.Final . It is
the Hibernate Validator, that is of version 6.0.10.Final  ( release date of
2018-05-15 ) ( please see: http://hibernate.org/validator/releases/6.0/ ).


Hibernate 6 is made reference in file:
https://github.com/jbonofre/karaf/blob/DEV_GUIDE/examples/karaf-jpa-example/karaf-jpa-example-features/src/main/feature/feature.xml

as hibernate

I guess, this is wrong.

OK, so I changed to hibernate . Maven
clean install ( inside examples folder ) and started Karaf again with:

$ JAVA_HOME=/opt/jdk ./bin/karaf clean debug


And after this change I get this error :

ERROR [Karaf local console user karaf] Exception caught while executing

Hi,

dear Jean-Baptiste Onofré. I am talking about this repository. It does not
work.

I've checked out https://github.com/jbonofre/karaf/tree/DEV_GUIDE

$ git clone -b DEV_GUIDE https://github.com/jbonofre/karaf/tree/DEV_GUIDE

Build it with maven:

$ mvn -DskipTests -Pfastinstall clean install

Went to the distribution/assembly:

$ cd assemblies/apache-karaf/target/assembly/

and started Karaf from here:
