<jdbc:connector name="jdbcConnector" dataSource-ref="jdbcDataSource">
    <jdbc:query key="updateShippingTimes" value="UPDATE orders set estimatedShipping = #[payload:options:b] WHERE sellableId = #[payload:sellable:sellableId]"/>\
</jdbc:connector>

payload:options:b is wrong.. what should it be to get the second entry in the hash?

I'm not sure if payload:sellable:sellableId is correct either...

Called by soemething like

 <opensky:flow name="Shipment Time Change" loggingCategory="com.opensky.osis.trebuchet" overrideLoggingCategory="true">
        <vm:inbound-endpoint path="sellable.estimated_shipping_change"/>

        <json:json-to-object-transformer returnClass="java.util.HashMap" />
        <jdbc:outbound-endpoint queryKey="updateShippingTimes"/>
</opensky:flow>
