WSO2 ESB not roll backing in transcation with MySQL - mysql

Question

I am trying transaction management in wso2 esb. I have a single database and a proxy to test transaction management, success case is working properly, but failure case it is not roll backing.
My Proxy:
<proxy name="a" transports="http https jms" startOnLoad="true">
<description/>
<target>
<inSequence>
<send>
<endpoint>
<address uri="http://localhost:9000/services/SimpleStockQuoteService"/>
</endpoint>
</send>
</inSequence>
<outSequence>
<transaction action="new"/>
<log level="custom">
<property name="text" value="** Reporting to the Database esbdb**"/>
</log>
<dbreport useTransaction="true">
<connection>
<pool>
<dsName>jdbc/db</dsName>
</pool>
</connection>
<statement>
<sql>delete from company1 where name =?</sql>
<parameter xmlns:m1="http://services.samples/xsd"
xmlns:m0="http://services.samples"
expression="//m0:return/m1:symbol/child::text()"
type="VARCHAR"/>
</statement>
</dbreport>
<log level="custom">
<property name="text" value="** Reporting to the Database esbdb1**"/>
</log>
<dbreport useTransaction="true">
<connection>
<pool>
<dsName>jdbc/db</dsName>
</pool>
</connection>
<statement>
<sql>INSERT into company2 values (?,'c4',?)</sql>
<parameter xmlns:m1="http://services.samples/xsd"
xmlns:m0="http://services.samples"
expression="//m0:return/m1:symbol/child::text()"
type="VARCHAR"/>
<parameter xmlns:m1="http://services.samples/xsd"
xmlns:m0="http://services.samples"
expression="//m0:return/m1:last/child::text()"
type="DOUBLE"/>
</statement>
</dbreport>
<transaction action="commit"/>
<send/>
</outSequence>
<faultSequence>
<property name="SET_ROLLBACK_ONLY" value="true" scope="axis2"/>
<log level="custom">
<property name="Transaction Action" value="Rollbacked"/>
</log>
<transaction action="rollback"/>
</faultSequence>
</target>
</proxy>
My master-datasource.xml
<providers>
<provider>org.wso2.carbon.ndatasource.rdbms.RDBMSDataSourceReader</provider>

<datasources>
<datasource>

</dataSourceProps>
</configuration>
</definition>
</datasource>
What could be the problem?
Note: I have also tried with https://docs.wso2.com/display/ESB481/Transaction+Mediator+Example having one database and 2 tables in it, but with MySQL.

I think you are missing the
<send/>
Tag at the end of your fault sequence. Your fault sequence should be as follows.
<faultSequence>
<property name="SET_ROLLBACK_ONLY" value="true" scope="axis2"/>
<log level="custom">
<property name="Transaction Action" value="Rollbacked"/>
</log>
<transaction action="rollback"/>
<send/>
</faultSequence>
