Re: [jboss-user] [JBoss Microcontainer] - About JBoss5 classloader

nesta fdb [http://community.jboss.org/people/jnesta] replied to the discussion "About JBoss5 classloader" To view the discussion, visit: http://community.jboss.org/message/555092#555092 -------------------------------------------------------------- Hi Ales, Thank you very much. A.java snippet public class A {      public void start() {           System.out.println(this.getClass()..getClassLoader());           // and print parent and ancestor classloader           System.out.println(new B());      } } When JBoss starts, NoClassDefFoundError is thrown out. According to my understanding, two BaseClassLoader instances for a.beans and b.beans share a same class repository (DefaultDomain). If B is visible to A, then BaseClassLoader for a.beans can load class B. The scenario contains servel steps: 1. BaseClassLoaders are registered to class repository (DefaultDomain) 2. BaseClassLoader for a.beans trys to load class B, and it trys from class repository, but it can't find. 3. Because BaseClassLoader for b.beans declares that it can load class B 4. Class repository delegates BaseClassLoader for b.beans to load class B But this doesn't explain why NoClassDefFoundError happens. Another question: When is contextClassLoader of current thread set in JBoss5?
