EasyBeans und Equinox





After the decision to design my upcoming ERP solution as OSGI - Client/Server application using Eclipse Riena (Remoting, ObjectTransactions), Equinox (OSGI) and Hibernate (JPA / ORM) one point remains open: how to integrate EJB (Stateless and Stateful Sessionbeans) ?

The answer: there's a great open source EJB - OSGI solution: EasyBeans.

First step:

Integrate EasyBeans with Eclipse 3.4 + Equinox 3.4. (EasyBeans default OSGI framework is Felix from Apache)

... here's my HowTo:

What do we need: Eclipse Platform SDK, Equinox SDK and Easybeans OSGI - Hibernate-Version. All tests are done and are only running under Eclipse 3.4. At the moment of writing this blog Eclipse 3.4.RC3 is the newest one and EasyBeans OSGI 1.0.0:

We have to differentiate between Eclipse as IDE and as target platform. At first you should install Eclipse Platform SDK as IDE as usual.

If you want to follow this tutorial then you should create a folder structure for the target platform as below.

To make the configuration and installation portable, we define a variable in Eclipse pointing to the root of our target files: ${target_easybeans}.



Then we create the following structure at

${target_easybeans}/

No we have to copy the needed plug-ins (bundles).

Which plug-ins you should copy depends on the needs of your project - to be flexible I made examples for two different target platforms: easybeans_target_full and easybeans_target_minimal.

You can download the two target definition files to import them into your Eclipse project: easybeans_target_full.target.zip and easybeans_target_minimal.target.zip.

easybeans_target_full (complete environment)

please copy into ${target_easybeans}/easybeans_target_full/eclipse/configuration/plugins:

  • all from Eclipse Platform SDK plugins - folder
  • all from Equinox SDK plugins - Ordner, if not contained in Platform SDK - Plugins)
  • from ow2-easybeans-osgi-1.0.0/bundles: all without *.felix.*

easybeans_target_minimal (Target Platform only with needed bundles)

please copy into ${target_easybeans}/easybeans_target_minimal/eclipse/configuration/plugins:

from Equinox SDK:

  • org.eclipse.osgi
  • org.eclipse.equinox.common
  • org.eclipse.osgi.services
  • org.eclipse.equinox.cm
  • org.eclipse.equinox.ds
  • org.eclipse.equinox.log
  • org.eclipse.equinox.util
from EasyBeans bundles:
  • ow2-bundles-externals-commons-logging
  • easybeans-core
  • easybeans-component-carol
  • easybeans-component-hsqldb
  • easybeans-component-jdbcpool
  • easybeans-component-joram
  • easybeans-component-jotm
  • easybeans-component-quartz
  • easybeans-agent

if wanted also the examples - bundles from EasyBeans:

  • easybeans-example-osgi
  • easybeans-examples-entitybean
  • easybeans-examples-mdb
  • easybeans-examples-migrationejb21
  • easybeans-examples-security
  • easybeans-examples-statefulbean
  • easybeans-examples-statelessbean
  • easybeans-examples-timerservice

Warning

  1. Bundles from EasyBeans (Version 1.0.0) were not named like Equinox - rules: easybeans-core-1.0.0 should be easybeans-core_1.0.0. You can simple rename the bundles (change minus inti underline) or to use the name together with the version if adding bundles to bundle.info from config.ini. (Bug JIRA)

  2. Bundle easybeans-component-joram-1.0.0 contains a wrong import in MANIFEST.MF: com.scalagent.scheduler This import must be removed. (Bug JIRA)

Its always a good idea to define Target Definition files for your target platforms in Eclipse: Menu File-->New-->Target Definition



After defining the targets you can change to this target with one click from within the target definition file or you do it directly from Preferences - Plug-in Development - Target Platform:


Please check the box (yellow marked). Because we want to build the target platform only using the plug-ins (bundles) stored at target platform location. (see the blog from Chris Aniszczyk)

To start EasyBeans easy ;-) in Eclipse we create OSGI Launch configurations.
Run Configurations...
We need two different OSGI Launch configurations:



  • first launcher uses a configuration file (config.ini in folder configuration), where all bundles were listed under property bundle.info
  • second launcher runs without using a configuration file - all bundles and arguments are defined directly in the launch configuration

OSGI Framework Launch Configuration with config.ini


There are no bundles selected from target platform, because they are all listed inside config.ini.



The most important program argument is -configuration, you also see the use of the defined variable. Inside this configuration folder you have to place the config.ini.

Content of config.ini:

Its no application - we only want to run these bundles:
  • eclipse.ignoreApp=true
  • osgi.noShutdown=true
Following bundles have to be installed and partly to be started from OSGI framework:
  • osgi.bundles=\
  • org.eclipse.equinox.common@2:start, \
  • org.eclipse.osgi.services@start, \
  • org.eclipse.equinox.cm@start, \
  • org.eclipse.equinox.ds@start, \
  • org.eclipse.equinox.log@start, \
  • org.eclipse.equinox.util@start, \
  • ow2-bundles-externals-commons-logging-1.0.5@start, \
  • easybeans-core-1.0.0, \
  • easybeans-component-carol-1.0.0, \
  • easybeans-component-hsqldb-1.0.0, \
  • easybeans-component-jdbcpool-1.0.0, \
  • easybeans-component-joram-1.0.0, \
  • easybeans-component-jotm-1.0.0, \
  • easybeans-component-quartz-1.0.0, \
  • easybeans-agent-1.0.0@start, \
  • easybeans-example-osgi-1.0.0, \
  • easybeans-examples-entitybean-1.0.0, \
  • easybeans-examples-mdb-1.0.0, \
  • easybeans-examples-migrationejb21-1.0.0, \
  • easybeans-examples-security-1.0.0, \
  • easybeans-examples-statefulbean-1.0.0, \
  • easybeans-examples-statelessbean-1.0.0, \
  • easybeans-examples-timerservice-1.0.0
Informations about bootdelegation - these packages are loaded from system classloader:
  • org.osgi.framework.bootdelegation=sun.*,com.sun.*
System packages - these packages are exported from the OSGI system bundle and can be imported from other bundles:

Even while testing its a good idea to use an own location for the Configuration Area in the settings of the launch configuration. (We also use our above defined variable here).

Here you can download the launch configuration: easybeans (bundle.info in config.file).launch.zip
And the config.ini for this scenario: config.ini.zip

OSGI Framework Launch Configuration without config.ini

In this case you have to select the needed bundles in the launcher.

Please watch the Start Level: equinox.common needs Level 2, all the other bundles get automatically the Default Start Level 4 and then the easybeans.agent with Start Level 5 will be started.

The other bundles from easybeans have set Auto-Start = false, because its the task of the easybeans.agent to start them in the right order.


At programm arguments there's no -configuration - of course all of them now have to be defined as VM Arguments.

Please watch, that -Dorg.osgi.framework.system.packages has to be entered without any spaces - the other arguments are identical to the content of the config.ini in the first scenario.

And here's the launch configuration to Download: easybeans (launch config).launch.zip

YOU ARE READY - all configuration and installation is done and you can run EasyBeans with different target platforms and different OSGI Framework launch configurations.

Framework is launched.

Good luck and have fun with EasyBeans. In some days I'll report my experiences how to run EasyBeans and Eclipse Riena together.

Hi ekke,

After Integrate EasyBeans with Eclipse proceed this "how to".

I’m getting this error on OSGI. It’s possible to fix this?

hi missias,
the stacktrace isn't enough to see what went wrong.
at the moment I'm on vacation and have not much time to look into it.
but I'll place soon a new blog entry about integration of Easybeans 1.1.0 + Riena M3 (or upcoming M4) + Eclipse / Equinox 3.4
this works great, but there are some pitfalls to watch.
