public void	ejbPassivate()
public void	ejbRemove()
public java.lang.Object	getAttribute(javax.management.ObjectName name, java.lang.String attribute) Gets the value of a specific attribute of a named MBean. The MBean is identified by its object name. param name The object name of the MBean from which the attribute is to be retrieved. param attribute A String specifying the name of the attribute to be retrieved. return The value of the retrieved attribute. exception AttributeNotFoundException The attribute specified is not accessible in the MBean. exception MBeanException Wraps an exception thrown by the MBean's getter. exception InstanceNotFoundException The MBean specified is not registered in the MBean server. exception ReflectionException Wraps a java.lang.Exception thrown when trying to invoke the setter. exception RuntimeOperationsException Wraps a java.lang.IllegalArgumentException: The object name in parameter is null or the attribute in parameter is null. return this.mejbHelper.getAttribute(name,attribute);
public javax.management.AttributeList	getAttributes(javax.management.ObjectName name, java.lang.String[] attributes) Enables the values of several attributes of a named MBean. The MBean is identified by its object name. param name The object name of the MBean from which the attributes are retrieved. param attributes A list of the attributes to be retrieved. return The list of the retrieved attributes. exception InstanceNotFoundException The MBean specified is not registered in the MBean server. exception ReflectionException An exception occurred when trying to invoke the getAttributes method of a Dynamic MBean. exception RuntimeOperationsException Wrap a java.lang.IllegalArgumentException: The object name in parameter is null or attributes in parameter is null. return this.mejbHelper.getAttributes(name,attributes);
public java.lang.String	getDefaultDomain() Returns the default domain used for naming the managed object. The default domain name is used as the domain part in the ObjectName of managed objects if no domain is specified by the user. return this.mejbHelper.getDefaultDomain();
public ListenerRegistration	getListenerRegistry() return this.mejbHelper.getListenerRegistry();
public java.lang.Integer	getMBeanCount() Returns the number of MBeans registered in the MBean server. try{ return this.mejbHelper.getMBeanCount(); }catch(Exception ex){ throw new RemoteException(this.toString() +"::getMBeanCount", ex); }
public javax.management.MBeanInfo	getMBeanInfo(javax.management.ObjectName name) This method discovers the attributes and operations that an MBean exposes for management. param name The name of the MBean to analyze return An instance of MBeanInfo allowing the retrieval of all attributes and operations of this MBean. exception IntrospectionException An exception occurs during introspection. exception InstanceNotFoundException The MBean specified is not found. exception ReflectionException An exception occurred when trying to invoke the getMBeanInfo of a Dynamic MBean. return this.mejbHelper.getMBeanInfo(name);
public java.lang.Object	invoke(javax.management.ObjectName name, java.lang.String operationName, java.lang.Object[] params, java.lang.String[] signature) Invokes an operation on an MBean. param name The object name of the MBean on which the method is to be invoked. param operationName The name of the operation to be invoked. param params An array containing the parameters to be set when the operation is invoked param signature An array containing the signature of the operation. The class objects will be loaded using the same class loader as the one used for loading the MBean on which the operation was invoked. return The object returned by the operation, which represents the result ofinvoking the operation on the MBean specified. exception InstanceNotFoundException The MBean specified is not registered in the MBean server. exception MBeanException Wraps an exception thrown by the MBean's invoked method. exception ReflectionException Wraps a java.lang.Exception thrown while trying to invoke the method. return this.mejbHelper.invoke(name,operationName,params,signature);
public boolean	isRegistered(javax.management.ObjectName name) Checks whether an MBean, identified by its object name, is already registered with the MBean server. param name The object name of the MBean to be checked. return True if the MBean is already registered in the MBean server, false otherwise. try{ return this.mejbHelper.isRegistered(name); }catch(Exception ex){ throw new RemoteException(this.toString() +"::isRegistered", ex); }
public java.util.Set	queryNames(javax.management.ObjectName name, javax.management.QueryExp query) Gets the names of managed objects controlled by the MEJB. This method enables any of the following to be obtained: The names of all managed objects, the names of a set of managed objects specified by pattern matching on the ObjectName and/or a Query expression, a specific managed object name (equivalent to testing whether an managed object is registered). When the object name is null or no domain and key properties are specified, all objects are selected (and filtered if a query is specified). It returns the set of ObjectNames for the managed objects selected. param name The object name pattern identifying the managed objects to be retrieved. If null or no domain and key properties are specified, all the managed objects registered will be retrieved. param query The query expression to be applied for selecting managed objects. If null no query expression will be applied for selecting managed objects. return A set containing the ObjectNames for the managed objects selected. If no managed object satisfies the query, an empty list is returned. try{ return this.mejbHelper.queryNames(name,query); }catch(Exception ex){ throw new RemoteException(this.toString() +"::queryNames", ex); }
public void	setAttribute(javax.management.ObjectName name, javax.management.Attribute attribute) Sets the value of a specific attribute of a named MBean. The MBean is identified by its object name. param name The name of the MBean within which the attribute is to be set. param attribute The identification of the attribute to be set and the value it is to be set to. return The value of the attribute that has been set. exception InstanceNotFoundException The MBean specified is not registered in the MBean server. exception AttributeNotFoundException The attribute specified is not accessible in the MBean. exception InvalidAttributeValueException The value specified for the attribute is not valid. exception MBeanException Wraps an exception thrown by the MBean's setter. exception ReflectionException Wraps a java.lang.Exception thrown when trying to invoke the setter. exception RuntimeOperationsException Wraps a java.lang.IllegalArgumentException: The object name in parameter is null or the attribute in parameter is null. this.mejbHelper.setAttribute(name,attribute);
public javax.management.AttributeList	setAttributes(javax.management.ObjectName name, javax.management.AttributeList attributes) Sets the values of several attributes of a named MBean. The MBean is identified by its object name. param name The object name of the MBean within which the attributes are to be set. param attributes A list of attributes: The identification of the attributes to be set and the values they are to be set to. return The list of attributes that were set, with their new values. exception InstanceNotFoundException The MBean specified is not registered in the MBean server. exception ReflectionException An exception occurred when trying to invoke the getAttributes method of a Dynamic MBean. exception RuntimeOperationsException Wraps a java.lang.IllegalArgumentException: The object name in parameter is null or attributes in parameter is null. return this.mejbHelper.setAttributes(name,attributes);
public void	setSessionContext(SessionContext context) ctx = context;
