Subject RE: Using Struts2 OSGi plugin with GlassFish
Date Wed, 09 Jan 2013 23:15:41 GMT

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 ?
