Yes that is it.
But we do not try to run samples after changing some configurations
therefore you could get some exceptions.
I will look at in the evening to run ejb samples.

Hi Gurkan,
Thanks for the details.
I have been building the OWB from the trunk and followed the
readme which is based on M3, the M4 specific readme is not yet
available.
I did understand that we need the place the common jars specific
to jsr330/jsr299 in the $TOMCAT/lib and configure the openejb in
tomcat.
After this we should be able to deploy the ejb-sample.war in the
$TOMCAT/webapps, pretty simple!
Is there anything else I should look from configuration perspective?
Here is what I see from the Tomcat console currently
***********************************************************************************************

Hello Vicky;
Some configuration file names are changed. README_M3 is a
little bit old with respect to openwebbeans.properties
content. We have a plan to release M4 this week that it
contains lots of bug fixes. Therefore instead of using M3
artifacts, until M4 releases, checkout source from SVN and
build it yourself.
>>> "atinject-api-1.0.0-incubating-M3.jar....
at-inject.(JSR-330 API).jar and cdi.jar (JSR-299 API) projects
have moved to geronimo specs. You can download it from
http://repo1.maven.org/maven2/org/apache/geronimo/specs/
manually or if you use "maven", you can define dependencies to
them looking at pom content fro there.
Locations :
----------------------------
http://repo1.maven.org/maven2/org/apache/geronimo/specs/geronimo-atinject_1.0_spec/
http://repo1.maven.org/maven2/org/apache/geronimo/specs/geronimo-jcdi_1.0_spec/
You have to add those jars into TOMCAT lib folder.
>>>WEB-INF/lib, I don't understand what does this mean, it is
not clear.
It means that some of the libraries (jars) that OWB needs are
not contained in Tomcat. You have to manually add those jars
into your application WEB-INF/lib. For example, if you create
a JSF application, add JSF jars into WEB-INF/lib with OWB JSF
plugin. Another example is that OWB needes validator.jar.
Generally you have to add implementation jar(webbeans-impl)
and its dependencies to application WEB-INF/lib except
atinject.jar and cdi.jar. webbeans-impl jar must be reside in
WEB-INF/lib folder of the application, not in TOMCAT/lib folder.
For Configuration:
------------------------
openwebbeans-default.properties does not use EJB meta-data
discovery as default. To use EJB discovery you have to tweak
some properties. Look at
http://svn.apache.org/repos/asf/openwebbeans/trunk/samples/ejb-sample/src/main/resources/META-INF/openwebbeans/openwebbeans.properties.
Moreover, README_M3 talked about resource plugin that was
responsibe for injecting Java EE resources into bean (For
example, EntityManager, DataSource etc.). There is no
ResourcePlugin in current codebase. It has removed. Now, there
is a ResourceInjectionService. You have to configure this
service in openwebbeans.properties to use OpenEJB resource
injection service instead of default. (Look at ejb-sample
openwebbeans.properties).
Currently OWB looks for
META-INF/openwebbeans/openwebbeans.properties files to run
over default configuration properties. If you have a JAR that
is located in Tomcat LIB folder that contains
META-INF/openwebbeans/openwebbeans.properties file, it is read
by OWB.
One more thing, OWB uses EJB interceptor
(OpenWebBeansEJBInterceptor) to inject dependencies to EJB
beans. Therefore your every session bean must have this
interceptor. Again look at samples.
Please look at ejb-sample application for current configuration.
You can also join us on freenode channel on #IRC with
#openwebbeans channel.
Thanks;

Hi Folks,
I am in process of testing openwebbean with
Tomcat/openejb, I
did read the related section from the following docs
https://svn.apache.org/repos/asf/openwebbeans/trunk/readme/README_M3.txt
Here is the section which explains it
********************************************************************************************
EJB Support via Embeddable OpenEJB Container in Tomcat 6.X
---------------------------------------------
Configuration Steps:
--------------------------------------------
1* Download Tomcat 6.X version
2* Configure OpenEJB. Look at URL
http://openejb.apache.org/tomcat.html for installation.
3* Copy "atinject-api-1.0.0-incubating-M3.jar" to
Tomcat /lib
folder.
4* Copy "openwebbeans-api-1.0.0-incubating-M3.jar"
5* Look at ejb-sample.war for "WEB-INF/lib" libraries to
develop custom application.
You can also look at a source of the project.
********************************************************************************************
"atinject-api-1.0.0-incubating-M3.jar" does not get
generated
at atinject-tck location, I was expecting it to be
there. It
is not there, I did pull the CDI api jar and dropped it
in the
$TOMCAT_HOME/lib.
"openwebbeans-api-1.0.0-incubating-M3.jar" should also be
copied to the $TOMCAT/lib, this should be pointed in the
instructions too.
>>Look at ejb-sample.war for "WEB-INF/lib" libraries to
develop custom application.
I don't understand what does this mean, it is not clear.
********************************************************************************************
How to Develop EJB Applications
---------------------------------------------
1* Add "META-INF/openwebbeans.properties" into your
application classpath.
2* Add
"org.apache.webbeans.spi.deployer.UseEjbMetaDataDiscoveryService=true"
to use EJB functionality.
So OWB container looks for EJBs.
3* Add
"org.apache.webbeans.resource.spi.ResourceService=org.apache.webbeans.spi.ee.openejb.resource.OpenEjbResourceServiceImpl"
to
use OpenEJB Resource injections.
4* Add "openwebbeans-ejb", "openwebbeans-resource" and
"openwebbeans-geronimo" plugins into your web application
classpath.
It adds EJB, Resource and Open EJB Resource plugins
into your
application.
5* If you want to use other plugins, add respective plugins
into your application classpath. For example, if you
wish to use
JSF framework, you add "openwebbeans-jsf" plugin.
6* Add OWB related interceptor into your EJB Beans. This is
called
"org.apache.webbeans.ejb.interceptor.OpenWebBeansEjbInterceptor"
This is needed for OWB injections.
7* Update your application's "web.xml" to add OWB specific
configuration.
---------------------------------------------
********************************************************************************************
Why can't we have this openwebbeans.properties as a part of
the jars which we have dropped in $TOMCAT/lib, it is
not good
idea to configure the classpath for the Tomcat and then
start.
I see the default properties file being here
https://svn.apache.org/repos/asf/openwebbeans/trunk/webbeans-impl/src/main/resources/META-INF/openwebbeans/openwebbeans-default.properties
This does not contain the property values as mentioned
in "How
to Develop EJB Applications", I was thinking of taking the
same file setting it to the Tomcat CP.
I have been able to configure the openEJB for Tomcat
and have
not yet followed the instructions to set the
META-INF/openwebbeans.properties and hence getting this
error
*******************************************************************************
context path = /ejb-sample
23 Feb, 2010 1:33:28 PM
org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
*******************************************************************************
Before digging more into the code and finding the details I
would like to know more from the community.
Regards,
Vicky
