How can I change default port number of Activemq

I am using Windows 7 OS. I downloaded apache-activemq-5.8.0.zip from these Link and extracted in C:\Users\Infratab Bangalore\Desktop\Queueing\apache-activemq-5.8.0 directory.

While Activemq initialization time I read Pre-Installation Requirements concept from these Link.

I already installed apache-maven-3.0.5 in my system.For my conformation I run the following command in my system.

   mvn -version

I am getting the following message,So Maven is installed successfully.

 Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 19:21:
 28+0530)
 Maven home: P:\Software\apache-maven-3.0.5
 Java version: 1.7.0_21, vendor: Oracle Corporation
 Java home: C:\Program Files\Java\jdk1.7.0_21\jre
 Default locale: en_US, platform encoding: Cp1252
 OS name: "windows 7", version: "6.1", arch: "x86", family: "windows"

I downloaded geronimo-spec-corba-1.0.jar from these Link and set classpth.

I started Activemq initialization in the following way.

  C:\Users\Infratab Bangalore\Desktop\Queueing\apache-activemq-5.8.0\bin>activemq

I am getting error,So I tested whether 61616(Activemq default port no) is in active with the following statement.

  C:\Users\Infratab Bangalore>netstat -an|find "61616"
   TCP    0.0.0.0:61616          0.0.0.0:0              LISTENING
   TCP    [::]:61616             [::]:0                 LISTENING

Finally I understand 61616 port is active so I want to change my port number.

Am I right, what I am thinking?
How can I install Activemq.

Thanks.

I believe your problem is there is already something running on port 61616. (It could be another instance of ActiveMQ you started on accident).

You can change the port for ActiveMQ in the activemq.xml file. Just do a find on 61616 and replace it with the port you would like to use (it should be in the <transportConnector> tag with the name openwire).

You do not have to install ActiveMQ, simply launch activemq.bat in the bin folder to start the standalone service.
