soap - Mule ESB choice flow control route -


in mule have following flow : there choice flow control test input , verify if input string equals 'ctr1'.

    <flow name="mediationflow1" doc:name="mediationflow1">          <file:inbound-endpoint path="c:\mulestudio\sandbox\input" pollingfrequency="3000" responsetimeout="10000" doc:name="file"/>         <file:file-to-string-transformer doc:name="file string"/>         <choice doc:name="choice">             <when expression="payload=='ctr1'">                 <cxf:jaxws-client operation="find" serviceclass="services.port.portws" port="portwsport" enablemulesoapheaders="true" doc:name="port"/>                 <http:outbound-endpoint exchange-pattern="request-response" method="post" address="http://localhost:8080/actors/portws" doc:name="portws"/>             </when>             <otherwise >                 <cxf:jaxws-client operation="find" serviceclass="services.douane.douanews" port="douanewsport" enablemulesoapheaders="true" doc:name="douane"/>                 <http:outbound-endpoint exchange-pattern="request-response" method="post" address="http://localhost:8080/actors/douanews" doc:name="douanews"/>             </otherwise>         </choice>        <file:outbound-endpoint path="c:\mulestudio\sandbox\output" outputpattern="#[function:datestamp:dd-mm-yy]_#[function:systime].xml " responsetimeout="10000" doc:name="outgoing file"/>     </flow> </mule>

the both web services call works when run them speratly, when add choice ccontrol got :

i'm not sure if it's comming choice test expression ? altough cant find informations on how use choice control flow in details.

appreciate help. thank you.

mule default applies lot of transformers in flow convert payload required formats.

in case when there no choice router converts object returned xml string write file. choice router programmers responsibility provide transformer convert response object xml string.

add following mule-xml jaxb object xml transformer after choice router , before writing file-outbound.

 .....     </otherwise>  </choice>   <xm:jaxb-object-to-xml-transformer name="objecttoxml" jaxbcontext-ref="myjaxb"  returnclass="java.lang.string" encoding="utf-8"/>

hope helps.
