Execute stored procedure to select data - Mule 3.3.0 - sql-server

Question

I'm trying to execute a stored procedure to SELECT data from a SQL Server 2008 database using Mule 3.3.0.
In the Mule docs there is info about doing this with Oracle. I'm not sure if this is possible with SQL Server.
This is my Mule endpoint config
<jdbc:outbound-endpoint exchange-pattern="request-response" queryTimeout="-1" connector-ref="sqlServerConnector" queryKey="selectCoupons" doc:name="Database">
<jdbc:query key="selectCoupons" value="call sp_get_coupons()"/>
</jdbc:outbound-endpoint>
This is the output
Root Exception stack trace:
java.sql.SQLException: The executeUpdate method must not return a result set.
at net.sourceforge.jtds.jdbc.JtdsStatement.processResults(JtdsStatement.java:603)
at net.sourceforge.jtds.jdbc.JtdsStatement.executeSQL(JtdsStatement.java:546)
at net.sourceforge.jtds.jdbc.JtdsPreparedStatement.executeUpdate(JtdsPreparedStatement.java:506)
+ 3 more (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)
I'm using the jTDS driver. Testing the stored procedure with a JDBC client I get the expected resultSet.
Any suggestions?
