How to change response from text/plain to text/xml - wso2

Question

I have a service returns a text/plain content. The response message like:
RESP0Success"
But in ESB4.0.3, the response is like:
<text xmlns="http://ws.apache.org/commons/ns/payload"><?xml version="1.0" encoding="UTF-8"?><message><MsgType>RESP</MsgType><ReturnCode>0</ReturnCode><ReturnMessage>Success</ReturnMessage></message>
</text>
I set builder and formatter in axis2.xml. But no use.
<messageBuilder contentType="text/plain"
class="org.apache.axis2.format.PlainTextBuilder"/>
<messageFormatter contentType="text/plain"
class="org.apache.axis2.format.PlainTextFormatter"/>
Can anyxone tell me how to set the builder and formatter in axis2.xml? My service config is:
<proxy xmlns="http://ws.apache.org/ns/synapse" name="TextPlain" transports="https,http" statistics="disable" trace="disable" startOnLoad="true">
<target>
<inSequence>
<property name="ContentType" value="text/plain" scope="axis2" />
<log level="full" />
</inSequence>
<outSequence>
<log level="full" />
<property name="ContentType" value="text/plain" scope="axis2" />
<send />
</outSequence>
<endpoint>
<address uri="http://172.20.28.206:8080/AAAService/recieveMsg" format="pox">
</address>
</endpoint>
</target>
</proxy>

I've had the same problem, then I set
<property name="messageType" value="text/plain" scope="axis2"/>
and now it works, if i call it from URL, it will return only text.
<proxy xmlns="http://ws.apache.org/ns/synapse" name="RESTE" transports="http" statistics="disable" trace="disable" startOnLoad="true">
<target>
<inSequence>
<log level="full"/>
</inSequence>
<outSequence>
<log level="full"/>
<property name="messageType" value="text/plain" scope="axis2"/>
<send/>
</outSequence>
<endpoint>
<address uri="http://10.15.21.189:8180/contadorServicos/ola-mundo"/>
</endpoint>
</target>
<parameter name="serviceType">proxy</parameter>
<description></description>
</proxy>
Unfortunattely the Tryit functionality stoped working, now it giver the following error.
<parsererror xmlns="http://www.mozilla.org/newlayout/xml/parsererror.xml">Erro no processamento de XML: formatação incorreta Posição: http://xxxxxxx/services/RESTE?tryit# Número da linha 1, coluna 221:
<sourcetext><TryitProxyError h:status='SOAP envelope error' xmlns:h='http://wso2.org/ns/TryitProxy'>org.apache.axis2.AxisFault: com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character 'r' (code 114) in prolog; expected '<'at [row,col {unknown-source}]: [1,1]</TryitProxyError> ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------^</sourcetext>
</parsererror>
p.s: When I use other tools like SOAPUI, it works correctly.

You need to specify the ContentType of your message. As the input from the HTTP will contain the Soap envelope and body, your content is being included inside such a tag.
When you now tell your endpoint, that the message is of type text/plain, the PlainTextFormatter will convert it to real text and send it your endpoint (the axis2.xml is only the config - now you need to tell that you want to use now the PlainTextFormatter)
This line is missing:
<property name="ContentType" value="text/plain" scope="axis2"/>
