Hi All,
As Indika mentioned, we are getting the following error on MB startup.

I went through some of the tests in carbon-datasources and noticed that the
following was added in master-datasources.xml file :
<environment>
<property
name="java.naming.factory.initial">org.wso2.carbon.datasource.core.jndi.CustomContextFactory</property>
</environment>
It seems the issue is occurring because of the above configuration is not
available in MB master-datasources.xml. Do we need to implement a class
like "org.wso2.carbon.datasource.core.jndi.CustomContextFactory" ? Is it a
must have ?
