A connector is a collection of templates that define operations that call the APIs of a Cloud-based service like Twitter and JIRA. There users can call from their ESB configurations to easily access specific logic for processing messages. Typically, connectors are used to wrap the API of an external service. For example, there are several default connectors provided with the ESB , but you that call the APIs of services like Twitter and JIRA. You can also create your own connector to provide access to other services. Creating a connector involves the following high-level tasks:

...

connector.xml - Defines the connector name, package, and the different categories of operations that will be exposed for the connector. For example, the JIRA connector's connector.xml file looks like this:

Code Block

language	html/xml

<connector>
    <component name="jira" package="org.wso2.carbon.connectors">
        <dependency component="jira_config" />
        <dependency component="jira_dashboard"/>
        <dependency component="jira_filter"/>
        <dependency component="jira_group"/>
        <dependency component="jira_issue" />
        <dependency component="jira_project" />
        <dependency component="jira_search" />
        <dependency component="jira_user" />
        <description>JIRA 6.0 cloud connector</description>
    </component>
</connector>

For each of the categories you specify, you create a corresponding directory (as shown above in the directory tree), each of which contains a component.xml file.
