Here is the code to get the list of datasources configures using JMX:

public synchronized List<String> getDBPools() {

    return (List) WSSubject.doAs(this.adminSubject,
            new java.security.PrivilegedAction() {
                public Object run() {
                    // Subject is associated with the current thread context
                    return java.security.AccessController
                            .doPrivileged(new java.security.PrivilegedAction() {
                                public Object run() {
                                    List<String> result = new ArrayList<String>();

                                    try {
                                        Session session = new Session();

                                        // Get the ConfigService
                                        // implementation.
                                        ConfigService configService = ConfigServiceFactory
                                                .getConfigService();
                                        ObjectName dsType = ConfigServiceHelper
                                                .createObjectName(null,
                                                        "DataSource", null);
                                        ObjectName[] datasources = configService
                                                .queryConfigObjects(
                                                        session, null,
                                                        dsType, null);

                                        for (int i = 0; i < datasources.length; i++) {
                                            ObjectName dsObject = datasources[i];
                                            log

                                            log
                                                    .debug("OBJ ID = "
