[jboss-dev-forums] [Design of POJO Server] - VFS and JBossAS initialization

[alesj]

In order to speed/cache things up, I suggest the following addition:
bootstrap.xml

  | <bootstrap xmlns="urn:jboss:bootstrap:1.0">
  | 
  |    <url>initialize.xml</url>
  |    <url>classloader.xml</url>
  | 
Where initialize.xml would look like:

  | <!--
  |    The JBossAS initializer configuration.
  | -->
  | <deployment xmlns="urn:jboss:bean-deployer:2.0">
  | 
  |   <bean name="VFSCache">
  |     <constructor factoryClass="org.jboss.virtual.spi.cache.VFSCacheFactory" factoryMethod="getInstance"/>
  |     <uninstall method="stop"/>
  |   </bean>
  | 
  |   <bean name="JBossVFSInitializer" class="org.jboss.virtual.plugins.cache.PreInitializeVFSContexts">
  |     <property name="initializedVFSContexts">
  |       <list elementClass="java.net.URL">
  |         <value>${jboss.lib.url}</value>
  |         <value>${jboss.server.lib.url}</value>
  |       </list>
  |     </property>
  |   </bean>
  | 
  |   <bean name="SingletonSchemaResolverFactory" class="org.jboss.xb.binding.sunday.unmarshalling.SingletonSchemaResolverFactory">
  |     <constructor factoryClass="org.jboss.xb.binding.sunday.unmarshalling.SingletonSchemaResolverFactory" factoryMethod="getInstance"/>
  |     <install method="addJaxbSchema">
  |       <parameter>urn:jboss:caching-classloader:1.0</parameter>
  |       <parameter>org.jboss.classloading.spi.vfs.metadata.CachingVFSClassLoaderFactory10</parameter>
  |     </install>
  |   </bean>
  | 
  | </deployment>
  | 

The first bean just says we should stop cache after we're done.
The 2nd one pre-initializes some of the most commonly used vfs roots,
hence pushing matching contexts into vfs cache.
The last is VFSClassLoaderFactory metadata that works off the vfs cache.

I'm already running this, which results in this minimal cache:

What do you think?
