I've started working on my RailsStructure structure deployer again. I'm hoping to deploy "myapp.rails" which is just a JAR archive with a magical extension of ".rails". I've found that if I modify conf/deployers.xml and add <value>.rails</value> to the JARStructure, then my .rails archives are recognized as vfszip files, correctly. If my RailsStructure calls the underlying JarUtils.addJarSuffix( ".rails" ) in its own constructor, though, it fails to recognize my .rails file as a Jar, and ends up with a FileHandler handling it, instead of a JarHandler. public RailsStructure() { | setRelativeOrder( -10000 ); | JarUtils.addJarSuffix( ".rails" ); | } I've also attempted to do the install callback against JARStructure, with my RailsStructure implementing JarExtensionProvider. public String getJarExtension() { | return ".rails"; | } <install bean="JARStructure" method="addJarExtension"> | <parameter> | <this/> | </parameter> | </install> | <uninstall bean="JARStructure" method="removeJarExtension"> | <parameter> | <this/> | </parameter> | </uninstall> This also results in failure. I'd like to not have to have edits to deployers.xml, as that breaks the self-contained-ness of my deployer. But I seem otherwise unable to get ".rails" added as a vfszip-handleable type. Any pointers would be appreciated. Thanks! -Bob View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4193196#...
