As part of deploying SCA enhanced Web Applications in Geronimo

the MBE is to add SCA related EmbeddedRuntimeGBean to the web
application config which will deploy the application composite to
the SCA domain. The purpose of the NamingBuilder is to add SCA
Domain and other objects (required for injection of SCA references
in servlets etc.) into the WebAppContext. I am seeing that the
MBE and NamingBuilder GBeans which are added as part of the
Tuscany Plugin can not get dynamically added to the MBEs
configured in tomcat6-builder config and NamingBuilders configured
in j2ee-deployer config. The one option I see is to update the
plan.xml files in tomcat6-builder and j2ee-deployer configs and
rebuild the server. But this won't be like the MBE and
NamingBuilder is getting added as part of Tuscany-plugin
installation. The other option is to add (don't know if it is
easy to do this hack) the MBE and NamingBuilder to the
corresponding collections in TomcatModuleBuilder and NamingBuilder
GBeans. I appreciate any suggestions/comments or inputs on any
alternate approach that I am not seeing.
Yup, this is a problem. So far we've sidestepped it by just adding
all the known desired MBE's to the appropriate *-deployer plan, and
as you have found this is non-extensible.
I do not understand why overriding the relevant TomcatModuleBuilder
GBean pattern in config.xml does not work. This is better than having
to redeploy the tomcat6-builder plugin.
If the problem is to provide a way to update the tomcat6-builder
plugin when the Tuscany Plugin is installed, then an approach is to
package within the Tuscany plugin a script to update the reference
patterns of the GBean TomcatWebBuilder. For instance, by dropping a
file named
GBeansTuscanyEnhancer.groovy
in the folder
repository/org/apache/geronimo/configs/tomcat6-deployer/2.*/tomcat6-
deployer-2.*.car/
which kind of looks like (indicative...)
import org.apache.geronimo.gbean.AbstractNameQuery
def tomcatWebBuilderGBean = gbeanDatas.find { it.gbeanInfo.className
== 'org.apache.geronimo.tomcat.deployment.TomcatModuleBuilder' }
def moduleBuilderExtensionsPatterns =
tomcatWebBuilderGBean.getReferencePatterns('ModuleBuilderExtensions')
Set newPatterns = []
newPatterns.addAll(moduleBuilderExtensionsPatterns.patterns)
newPatterns.add(new AbstractNameQuery(new URI
(PUT_YOUR_TUSCANY_MBE_PATTERN_NAME_HERE)))
tomcatWebBuilderGBean.setReferencePatterns(newPatterns)
You should be done.
Thanks,

One possiblitly would be to define marker interfaces such as
WebMBE, EjbMBE, etc that the appropriate MBE's could implement and
use the interface in the references pattern.
Anyone have a better idea?
