[jboss-dev-forums] [Design of POJO Server] - JBBOOT - Event listener and ServerInitializer APIs

Moving the email discussion with ALR, to the forum: "jaikiran" wrote : > Hi Andrew, | > | > | > I was working on the JBBOOT-54 and had a few related questions: | > | > 1) In MCServer (impl-mc) what is the right time to expect the Kernel within the MC to be "set". Right now i see that it's being set during doStart() which is too late if someone wants to register to kernel events. I have this failing testcase (not committed) http://pastebin.com/m3979391c This fails because the kernel is not set. | "ALR" wrote : | Yep, I moved the bootstrap.run() and setup of the Kernel into the | initialize() method of AbstractMcServerBase. | | Commits: http://fisheye.jboss.org/changelog/JBossAS/?cs=87976 | "jaikiran" wrote : | > 2) I am bad (just learning more) at generics, this is more of a "is there a better way to do this" question - The LifecycleEventHandler has the following API: | > | > public void handleEvent(Server<MCServer, MCServerConfig> server, LifecycleState state) throws LifecycleEventException | > | > Assuming that the client registers a event handler for a MCServer event http://pastebin.com/m298f9c41is there a better was to work on a MCServer in the handleEvent method instead of doing a cast (line 26 in pastebin)? More importantly are there chances of getting a different type of server (i believe not, else it would be a bug), when the event handler was registered for MCServer? | "ALR" wrote : | The Lifecycle Event Handling API was stupid, because there's no need to | pass the server back into handleEvent(). So I removed this. Event | handlers that need to get at the server or Kernel (or whatever) can make | that an implementation detail supplied in the ctor, like: | | [url]http://fisheye.jboss.org/browse/JBossAS/projects/bootstrap/trunk/impl... | [/url] | Regarding your question about the generics, clearly they're wrong. And the same pattern is used in ServerInitializer. So I've got to revisit this and keep type safety (ideas welcome). | "jaikiran" wrote : > P.S: Is there an appropriate forum (user/dev) where we could discuss such questions? | "ALR" wrote : | Sure, we can abuse Design of POJO Server.
