  • How do I debug a Unity Container "Resolve"?

    - by willem
    I'm using the MS Unity container to do dependency injection, but a "Resolve" is returning unexpected results. Is there an way I can debug this resolution? It would be great if I could view what Types/Instances are registered in the container, but I can't see where this is stored when using QuickWatch. It would also be useful if I could get the container to output some debug Traces. Any suggestions?

  • Is it standard behavior for this code to throw a NullPointerException?

    - by Eric
    I've had a big problem in some library code, which I've pinned down to a single statement: System.out.println((String) null); Ok, the code doesn't actually look like that, but it certainly calls println with a null argument. Doing this causes my whole applicaio to throw an unexpected NullPointerException. In general, should println throw this exception under that circumstance, or is this non-standard behavior due to a poor implementation of the out instance?

  • Is it standard compliant to write font-size: 62.5%/1.2em in CSS?

    - by powerboy
    I noticed that some stylesheets have something like this: body { font-size: 62.5%/1.2em; } I got a warning "unexpected token /" when I wrote this in NetBeans. And if I changed the EM value, say, body { font-size: 62.5%/1em; } the computed font-size remained 16px. My question is, Is it standard compliant to write something like that? And how to computed the actual font-size?

  • Hudson on debian lenny

    - by Laurent
    Hello, I installed Hudson deamon on one server (running on debian lenny testing) some time ago. All was working until I perform an upgrade. At this time Hudson isn't accessible at port 8080 (which is the default port used). I have looked for iptables problems, however port 8080 is open in INPUT and OUTPUT. Configuration file in /etc/default/hudson seems okay, I haven't touch it. And if I do a ps aux | grep hudson, hudson deamon is running. Update 1: What is really strange for me is that in /var/log/hudson/hudson.log I get no error : [Winstone 2010/02/10 17:10:04] - Control thread shutdown successfully [Winstone 2010/02/10 17:10:04] - Winstone shutdown successfully Running from: /usr/share/hudson/hudson.war [Winstone 2010/02/10 17:10:43] - Beginning extraction from war file hudson home directory: /var/lib/hudson [Winstone 2010/02/10 17:10:44] - HTTP Listener started: port=8080 [Winstone 2010/02/10 17:10:44] - AJP13 Listener started: port=8009 [Winstone 2010/02/10 17:10:44] - Winstone Servlet Engine v0.9.10 running: controlPort=disabled 10 févr. 2010 17:10:44 hudson.model.Hudson$4 onAttained INFO: Started initialization 10 févr. 2010 17:10:44 hudson.model.Hudson$4 onAttained INFO: Listed all plugins 10 févr. 2010 17:10:44 hudson.model.Hudson$4 onAttained INFO: Prepared all plugins 10 févr. 2010 17:10:44 hudson.model.Hudson$4 onAttained INFO: Started all plugins 10 févr. 2010 17:10:46 hudson.model.Hudson$4 onAttained INFO: Loaded all jobs 10 févr. 2010 17:10:46 hudson.model.Hudson$4 onAttained INFO: Completed initialization 10 févr. 2010 17:10:47 org.springframework.context.support.AbstractApplicationContext prepareRefresh INFO: Refreshing org.springframework.web.context.support.StaticWebApplicationContext@caa559d: display name [Root WebApplicationContext]; startup date [Wed Feb 10 17:10:47 CET 2010]; root of context hierarchy 10 févr. 2010 17:10:47 org.springframework.context.support.AbstractApplicationContext obtainFreshBeanFactory INFO: Bean factory for application context [org.springframework.web.context.support.StaticWebApplicationContext@caa559d]: org.springframework.beans.factory.support.DefaultListableBeanFactory@40d2f5f1 10 févr. 2010 17:10:47 org.springframework.beans.factory.support.DefaultListableBeanFactory preInstantiateSingletons INFO: Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@40d2f5f1: defining beans [daoAuthenticationProvider,authenticationManager,userDetailsService]; root of factory hierarchy 10 févr. 2010 17:10:47 org.springframework.context.support.AbstractApplicationContext prepareRefresh INFO: Refreshing org.springframework.web.context.support.StaticWebApplicationContext@4d88a387: display name [Root WebApplicationContext]; startup date [Wed Feb 10 17:10:47 CET 2010]; root of context hierarchy 10 févr. 2010 17:10:47 org.springframework.context.support.AbstractApplicationContext obtainFreshBeanFactory INFO: Bean factory for application context [org.springframework.web.context.support.StaticWebApplicationContext@4d88a387]: org.springframework.beans.factory.support.DefaultListableBeanFactory@6153e0c0 10 févr. 2010 17:10:47 org.springframework.beans.factory.support.DefaultListableBeanFactory preInstantiateSingletons INFO: Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@6153e0c0: defining beans [filter,legacy]; root of factory hierarchy 10 févr. 2010 17:10:47 hudson.TcpSlaveAgentListener <init> INFO: JNLP slave agent listener started on TCP port 59750 Update 2: What I get with lsof -i -n -P | grep hudson: java 28985 hudson 97u IPv6 2002707 0t0 TCP *:8080 (LISTEN) java 28985 hudson 99u IPv6 2002708 0t0 TCP *:8009 (LISTEN) java 28985 hudson 147u IPv6 2002711 0t0 TCP *:59750 (LISTEN) java 28985 hudson 150u IPv6 2002712 0t0 UDP *:33848 I don't know what I can verify.
