[mule-user] Issue with RestServiceWrapper
prathamesh
Hi,
I have a Mule descriptor which takes as input a jms msg and converts it
into a String. I have used the following code form stock quote sample and
written a REST based web service which returns an xml file.
My mule descriptor:
<mule-descriptor name="RESTServiceWrapper"
implementation="org.mule.components.rest.RestServiceWrapper">
<inbound-router>
<global-endpoint name="inJMSGTA" transformers="ConvertObject"/>
</inbound-router>
<outbound-router>
<router
className="org.mule.routing.outbound.FilteringOutboundRouter">
<endpoint address="stream://System.out" transformers="XmlDecoder
Xslt XmlToObject"/>
</router>
</outbound-router>
<properties>
<property name="serviceUrl"
value="http://172.17.122.243:9090/test/FirstServlet"/>
<property name="payloadParameterName" value="price"/>
<property name="httpMethod" value="GET"/>
</properties>
</mule-descriptor>
The XML file returned is
<soapenv:Envelope>
<soapenv:Body>
<GetQuoteResponse
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<GetQuoteReturn xsi:type="xsd:string">accepted</GetQuoteReturn>
</GetQuoteResponse>
</soapenv:Body>
</soapenv:Envelope>
Now i have noticed that the web service does get called and also returns the
xml file when i do not apply the transformers on "the out stream". But i
would like to get the parsed element "accepted" instead of the whole XML
file. so i used the transformers mentioned in Stock Quote sample which uses
the same transformers for parsing a similar file. Yet I get the following
errors:
