  1. In the ESB Management Console, go to Manage -> Service Bus and click Source View.
  2. Insert the following XML configuration into the source view before the closing </definitions> tag to create the TestGoogle API:

    Code Block
    languagehtml/xml
     <api xmlns="http://ws.apache.org/ns/synapse"
         name="TestGoogle"
         context="/search">
       <resource methods="GET">
          <inSequence>
             <log level="full">
               <property name="STATUS" value="***** REQUEST HITS IN SEQUENCE *****"/>
             </log>
             <send>
                <endpoint>
                   <http method="get" uri-template="https://www.google.lk/search?q=wso2"/>
                </endpoint>
             </send>
          </inSequence>
       </resource>
       <handlers>
           <handler class="org.wso2.handler.SimpleOAuthHandlerSimpleOauthHandler"/>
       </handlers>
    </api>

    Notice that the <handlers> tag contains the reference to the custom handler class.

  3. Copy the custom handler.jar to the <ESB_HOME>/repository/components/libs directory.
  4. Open <ESB_HOME>/repository/conf/axis2/axis2.xml and add the following parameters:

    Code Block
    languagehtml/xml
    <!-- OAuth2 Token Validation Service -->
    <parameter name="oauth2TokenValidationService">https://localhost:9444/services/OAuth2TokenValidationService</parameter>
    <!-- Server credentials -->
    <parameter name="identityServerUserName">admin</parameter>
    <parameter name="identityServerPw">admin</parameter>
  5. Restart the ESB.
