[jboss-jira] [JBoss JIRA] Resolved: (JBAS-6002) NPE for JSF managed beans.

NPE for JSF managed beans. --------------------------- Key: JBAS-6002 URL: https://jira.jboss.org/jira/browse/JBAS-6002 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Web (Tomcat) service Affects Versions: JBossAS-5.0.0.CR2 Reporter: Emanuel Muckenhuber Assignee: Emanuel Muckenhuber Fix For: JBossAS-5.0.0.GA Copying from: JBAS-5673 Stan Silvert - 28/Sep/08 04:54 PM I'm reopening this because the fix can cause a NPE for JSF managed beans. I changed the JSF integration test in the testsuite. If you run org.jboss.test.web.test.JSFIntegrationTestCase you will see the NPE. I used a JButton as a managed bean in faces-config.xml like this: <managed-bean> <description>Use a swing JButton as a simple javabean</description> <managed-bean-name>myJButton</managed-bean-name> <managed-bean-class>javax.swing.JButton</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> <managed-property> <property-name>text</property-name> <value>Initial Value</value> </managed-property> </managed-bean> Note that this is an odd example. I'm not actually using JButton for anything other than the fact that I can use it as a holder to getText()/setText(). But it is perfectly valid to use a JDK class for this purpose. The NPE is in TomcatInjectionContainer.isDymanicBean() where it says: // Check if the object was loaded by a dynamic class loader (e.g. Jasper) String classLoaderName = object.getClass().getClassLoader().getClass().getName(); if(dynamicClassLoaders.contains(classLoaderName)) return true; Since JButton is loaded by the bootstrap classloader, object.getClass().getClassLoader() will return null and you get a NPE.
