setAttribute does not find correct method ----------------------------------------- Key: JBAS-1706 URL: https://jira.jboss.org/jira/browse/JBAS-1706 Project: JBoss Application Server Issue Type: Feature Request Security Level: Public(Everyone can see) Components: JMX Affects Versions: JBossAS-4.0.1 Final, JBossAS-4.0.1 SP1, JBossAS-4.0.2RC1 Reporter: Michael Kopp Assignee: Dimitris Andreadis The setAttribute searches for a method: Class[] clArr = null; if (attribute.getValue() != null) { clArr = new Class[]{attribute.getValue().getClass()}; } Method method = implementation.getClass().getMethod("set" + attribute.getName(), clArr); This means that if the value is DomElement, the class would be a org.apache.xerces.dom.DeferredElementImpl. But the Setter would normally reference org.w3c.dom.Element. The feature of jboss to support Element in a -service.xml is pretty useless this way. I think this should be done in the same way as Java5 does it. search for a method with the right name and the right number of parameters. for the found ones, check if the paramters are assignable. This way subclass and implementations of interfaces can be supported.
