Hallo, I try to deploy a MBean with EJB3 annotation on the server and call it from a sessionBean. The MBean looks like: | package trail.jmx; | | import org.jboss.annotation.ejb.Service; | import org.jboss.annotation.ejb.Management; | | @Service (objectName="trail:service=calculator") | @Management(Calculator.class) | public class CalculatorMBean implements Calculator { | | public double calculate (int start, int end, double saving) { | double tmp = Math.pow(1. + growthrate / 12., 12. * (end - start) + 1); | return saving * 12. * (tmp - 1) / growthrate; | } | .... | In My SessionBean I want to call it with: | private Object callXMB_Calculator(String operationName, Object[] params) | { | Object result = null; | | try | { | MBeanServer mbs = (MBeanServer) MBeanServerFactory.findMBeanServer(null).iterator().next(); | ObjectName oName = new ObjectName("jboss.j2ee:jar=CalcMBean.jar,name=CalculatorMBean,service=EJB3"); | | String[] signature = null; | if (params != null) | { | signature = new String[params.length]; | | for (int i = 0; i < params.length; ++i) | { | signature = params.getClass().getName(); | } | } | | result = mbs.invoke(oName, operationName, params, signature); | I call the function like this: | callXMB_Calculator("calculate", new Object[]{1,2,4d}); | But when I call the service-Method, I get a ReflectionException Caused by: java.lang.IllegalArgumentException: Unable to find operation calculate(java.lang.Integer,java.lang.Integer,java.lang.Double) When the server ist starting, I get the message: | 2008-05-02 09:30:35,281 INFO [org.jboss.ejb3.JmxKernelAbstraction] installing MBean: jboss.j2ee:jar=CalcMBean.jar,name=CalculatorMBean,service=EJB3 with dependencies: | 2008-05-02 09:30:35,468 INFO [org.jboss.ejb3.EJBContainer] STARTED EJB: trail.jmx.CalculatorMBean ejbName: CalculatorMBean | 2008-05-02 09:30:35,531 INFO [STDOUT] Calculator - Creating | To deploy the service, I have only copied the .jar file into the deploy directory. It contains only the .class files. With the use of 'old' XMBean' I have no problem, but I would prefere the EJB3 style. What can I do?
