运行ActiveMQ例子

JMS例子所有JMS都有统一的格式。每个例子都有自己的目录，它的内容包括： build.xml ant的build文件，用来运行例子。 src 目录例子的代码。 server0配置目录它包含了运行服务器所需要的配置文件。有的集群的例子可能有多个这样的目录，如server0, server1等。在运行每个例子时，都要先启动一个或多个单独的服务器。当例子运行完毕，再将它们停止。做为演示我们这里运行queue例子。其它的例子可以参见用户手册。首先打开一个命令行窗口（shell），进入到ActiveMQ的 examples/jms/queue目录。敲入命令./build.sh (或者在Windows上build.bat），你将看到如下的输出： Buildfile: build.xml run: init: compile: [echo] src.example.dir=/home/andy/projects/activemq/trunk/examples/jms/queue/src [javac] Compiling 5 source files to /home/andy/projects/activemq/trunk/examples/jms/queue /build/classes runExample: [java] 10:41:04,149 INFO @main [JMSExample] activemq.example.runServer is true [java] 10:41:04,149 INFO @main [JMSExample] starting server with config 'server0' logServerOutput true [java] 10:41:04,149 INFO @main [JMSExample] and vm args: -Xms512M,-Xmx512M,-XX:+U seParallelGC,-XX:+AggressiveOpts,-XX:+UseFastAccessorMethods,-Djava.util.logging.config. file=/home/andy/projects/activemq/trunk/examples/jms/common/../../../src/config/stand-alone/no n-clustered/logging.properties [java] org.apache.activemq.jms.example.SpawnedJMSServer out:10:41:08,437 INFO @main [Journal StorageManager] AIO journal selected [java] org.apache.activemq.jms.example.SpawnedJMSServer out:10:41:08,437 WARN @main [Journal StorageManager] AIO wasn't located on this platform, it will fall back to using pure Jav a NIO.

Java EE例子 Java EE的例子需要首先运行一个JEE应用服务器。这些例子包括MDB，Servlet，EJB等等。你首先要安装JBoss应用服务器。参见前面的章节进行安装。这里我们将用MDB例子来说明。有关其它例子的详细信息参见用户手册。首先确认JBoss应用服务器已经启动。如同其它Java EE例子一样，MDB需要部署到应用服务器。第一，将JBOSS_HOME环境变量指向你的应用服务器安装目录。如在Linux下： export JBOSS_HOME=/home/jbossas5.1/build/output/jboss-5.1.0.GA 然后就可以进行部署了。在examples/javaee/mdb目录下运行： ./build.sh deploy 它将创建一个“messaging"的AS配置，并用它来启动AS服务器。在命令行窗口你会看到如下的输出： Buildfile: build.xml validate-jboss: deploy: deploy-resources: [copy] Copying 1 file to /home/andy/projects/jbossas5.1/build/output/jboss-5.1.0.GA /server/default-with-activemq/deploy/activemq.sar [copy] Copying 1 file to /home/andy/projects/jbossas5.1/build/output/jboss-5.1.0.GA /server/default-with-activemq/deploy/activemq.sar init: compile: jar: [jar] Building jar: /home/andy/projects/activemq/trunk/examples/javaee/mdb/build/mdb-exa mple.jar ear: [jar] Building jar: /home/andy/projects/activemq/trunk/examples/javaee/mdb/build/mdb-exa mple.ear deploy-ear: [copy] Copying 1 file to /home/andy/projects/jbossas5.1/build/output/jboss-5.1.0.GA .......
