Configuring transports

WSO2 EI supports several transports that we can use when building our services, such as the following:

• JMS transport: This enables sending and receiving messages to queues and topics that implement the JMS specification
• Mailto transport: This enables sending emails
• VFS transport: Virtual File System (VFS) transport allows us to process files in a directory of the filesystem

We can enable this transport and many others in the <EI_HOME>/conf/axis2/axis2.xml file. All the transports available can be found in that file with a default configuration. We have to configure these transports for input and output connections. The input transports are configured using the transportReceiver XML tag, while the output transports are configured with the transportSender tag:

<transportSender name="jms" class="org.apache.axis2.transport.jms.JMSSender"/>
 
<transportReceiver name="jms" class="org.apache.axis2.transport.jms.JMSListener">
<parameter name="myTopicConnectionFactory" locked="false">
<parameter name="java.naming.factory.initial" locked="false">org.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
<parameter name="java.naming.provider.url" locked="false">conf/jndi.properties</parameter>
<parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">TopicConnectionFactory</parameter>
<parameter name="transport.jms.ConnectionFactoryType" locked="false">topic</parameter>
</parameter>
 
<parameter name="myQueueConnectionFactory" locked="false">
<parameter name="java.naming.factory.initial" locked="false">org.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
<parameter name="java.naming.provider.url" locked="false">conf/jndi.properties</parameter>
<parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
<parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
</parameter>
 
<parameter name="default" locked="false">

<parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
<parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
</parameter>
</transportReceiver>
