Exposing a JNDI Datasource

Java Naming and Directory Interface (JNDI) is a Java API (application programming interface) providing naming and directory functionality for Java software clients to discover and look up data and objects via a name. WSO2 Micro Integrator (WSO2 MI) supports the JNDI InitialContext implementation by inheriting the JNDI implementation of Tomcat ( http://tomcat.apache.org/tomcat-7.0-doc/jndi-resources-howto.html ). JNDI helps decouple object creation from the object look-up . When you have registered a datasource with JNDI, others can discover it through a JNDI lookup and use it.

Synapse configuration

Given below is the data service configuration you need to build. See the instructions on how to build and run this example.

<data name="jndi_dataservice" serviceNamespace="" serviceGroup="">
    <description/>
    <config id="jndi">
        <property name="jndi_context_class">com.sun.jndi.rmi.registry.RegistryContextFactory</property>
        <property name="jndi_provider_url">rmi://localhost:2199</property>
        <property name="jndi_resource_name">DataServiceSample</property>
        <property name="jndi_password">password</property>
    </config>
</data>

Build and run

Create the artifacts:

  1. Set up WSO2 Integration Studio.
  2. Create a Data Service project
  3. Create the data service with the configurations given above.
  4. Deploy the artifacts in your Micro Integrator.
