JBoss AS 7 JNDI 的常见异常

  1、对于jnp包的使用，jboss5中使用jnp，实现类是org.jnp.interfaces.NamingContextFactory，需要引 入jnp-client.jar。在AS7中客户端只需要引入一个jboss-client.jar的包使用的 java.naming.factory.initial改成了这个包下面的 org.jboss.naming.remote.client.InitialContextFactory。

                      jboss5下面的initialContext的实例化方法是

                                         Properties prop = new Properties();

                                         prop.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");

                                         prop.put("java.naming.provider.url","localhost:1099")

                                         prop.put("java.naming.factory.url.pkgs","org.jboss.naming")

                      jboss7中改成了

                                        Properties prop = new Properties();

                                        prop.put(Context.PROVIDER_URL, "remote://127.0.0.1:4447");

                                        prop.put(Context.SECURITY_PRINCIPAL, System.getProperty("username","appname"));

                                        prop.put(Context.SECURITY_CREDENTIALS, System.getProperty("password","12345"));

                                        prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");

                    否则会抛出Caused by: java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory
                                      at java.net.URLClassLoader$1.run(URLClassLoader.java:200)

                    2、注意到上面那个remote:127.0.0.1:4447,没有使用5.1里默认的localhost:1099,因为这个localhost和 127.0.0.1的区别访问不到JNDI，搞了好半天，这个banding IP可以在standalone/configration/standalone.xml文件里<integerface>配置

否则抛出

                    3、用户名密码，在jboss7里必须使用用户名和密码的验证，而且需要自己添加一个用户，一般用add-user.bat添加，选择Application User

                         Realm输入默认的ApplicationRealm

                          最后输入一行what roles do you want this user to belong to?

                          这里的输入与standalone.xml的内容匹配。我的项目是用到guest的

                          否则抛出

                     4、jndi命名，JBoss7使用了更加严格的JNDI命名比如 JMS的jms-connection-factories使用的是java:jboss/exported/jms /RemoteConnectionFactory而不是以前的/RemoteConnectionFactory我以为是 initialcontext.lookup的时候查找的内容是java:jboss/exported/jms /RemoteConnectionFactory，试了几次发现错了，应该是配置文件中的命名为java:jboss/exported/jms /RemoteConnectionFactory查找的时候用jms/RemoteConnectionFactory。同理查找Queue的时候在 standalone.xml中配置

                <jms-destinations>
                    <jms-queue name="myQueue">
                        <entry name="java:jboss/exported/queue/MyQueue"/>
                    </jms-queue>
                    <jms-queue name="SyslogQueue">
                        <entry name="java:jboss/exported/queue/SYSLOG"/>
                    </jms-queue>
                    <jms-queue name="TrapQueue">
                        <entry name="java:jboss/exported/queue/TRAP"/>
                    </jms-queue>
                    <jms-queue name="ICMPPingQueue">
                        <entry name="java:jboss/exported/queue/ICMPPING"/>
                    </jms-queue>
                </jms-destinations>

查找的时候用initialcontext.lookup("queue/MyQueue");

否则抛出

javax.naming.NameNotFoundException: jms/RemoteConnectionFactory -- service jboss.naming.context.java.jboss.exported.jms.RemoteConnectionFactory
at org.jboss.as.naming.ServiceBasedNamingStore.lookup(ServiceBasedNamingStore.java:97)

ps:发现一个问题上面说的第四点 我理解错了，我原来以为entry name="XXX/XXX"就是用来查找的所以把原来的<entry name="queue/SYSLOG"/>直接改成了<entry name="java:jboss/exported/queue/SYSLOG"/>然后启动时候没有报错但是会有几行提示信息

10:05:54,884 INFO  [org.hornetq.ra.inflow.HornetQActivation] (default-short-running-threads-threads - 3) Attempting to reconnect org.hornetq.ra.inflow.HornetQActivationSpec(ra=org.hornetq.ra.HornetQResourceAdapter@175c39c3 destination=queue/ICMPPING destinationType=javax.jms.Queue ack=Auto-acknowledge durable=false clientID=null user=null maxSession=15)

10:05:54,900 INFO  [org.hornetq.ra.inflow.HornetQActivation] (default-short-running-threads-threads - 3) awaiting topic/queue creation queue/ICMPPING

原来系统是根据entry name="XXX/XXX"来创建Queue的 所以entry name="XXX/XXX"（也就是<entry name="queue/SYSLOG">是不能去掉滴，否则提示找不到对应的Queue）要保留。
