RE: Using Struts2 OSGi plugin with GlassFish
The beauty of implementing a maven-plugin is that all attributes of the plugin are configurable
open struts2-osgi-plugin.jar
edit
.\META-INF\maven\plugin.xml
look for<bean name="osgi" type="com.opensymphony.xwork2.config.PackageProvider" class="org.apache.struts2.osgi.OsgiConfigurationProvider" />
as long as your com.opensymphony.xwork2.config.PackageProvider (felix provider) implements interfacescom.opensymphony.xwork2.config.PackageProviderorg.osgi.framework.BundleListener
then substitute in the felix PackageProvider to class attribute at
<bean name="osgi" type="com.opensymphony.xwork2.config.PackageProvider" class="org.apache.struts2.osgi.OsgiConfigurationProvider" />
save .\META-INF\maven\plugin.xml/close/rejar/place struts2-osgi-plugin.jar back into lib folder (after saving original as struts2-osgi-plugin.jar.original) if you do not redirect the PackageProvider this Struts-osgi-Listener will be called as seen here from Provider code org.apache.struts2.osgi.OsgiConfigurationProvider

//this class loader interface can be used by other plugins to lookup resources

correct
yes for all intents and purposes struts-osgi-plugin *is* a functional struts plugin
in order to interface to maven (plexus framework) we'll need to
1) port these attributes to \META-INF\maven\plugin.xml
<constant name="struts.objectFactory" value="osgi" />
<constant name="struts.objectFactory.delegate" value="struts" />
<constant name="struts.freemarker.manager.classname"
value="org.apache.struts2.osgi.BundleFreemarkerManager" /><!-- TBD: which FreemarkerManager to use with Maven 3.x -->
<constant name="struts.staticContentLoader"
value="org.apache.struts2.osgi.loaders.StaticContentBundleResourceLoader" /><!-- TBD: which StaticContentBundleResourceLoader to use with Maven 3.x -->
<constant name="struts.convention.action.includeJars" value="jar:file:.*?/bundles/.*?\.jar(!/)?" /> 2) convert Struts methods for org.apache.struts2.osgi.OsgiUtil.java translateBundleURLToJarURLand or org.apache.struts2.osgi.interceptor.OsgiInterceptor intercept method to goal annotation which will extends AbstractMojo@goal buildStruts2OSGIMojo extends org.apache.maven.plugin.AbstractMojo(execute method)
3)populate \META-INF\maven\plugin.xml
so..in order to participate in maven lifecycle ...
a)defaultGoal will be 'build'
b)default binding will bind to 'package' phase
community..what are we missing ?

Hi Martin.
In struts2-osgi-plugin.jar there is no .\META-INF\maven\plugin.xml file.
I assume you mean the .\struts-plugin.xml file? Also if I understand

that right?
