I have a sequence that perform a callout (blocking), because i need to extract some data from the response to create a payload to perform a new callout to another service.
The Callout
<callout action="nextSource" initAxis2ClientOptions="false"
serviceURL="http://192.168.0.33:9764/services/AltaLigeraService?wsdl">
<source type="envelope" />
<target key="myresponse" />
</callout>
So i can log the response:
<property expression="get-property('myresponse')"
name="rta" scope="default" type="STRING" />
<log level="custom">
<property expression="$ctx:rta" name="Respuesta" />
</log>
The response log is:
INFO - LogMediator Respuesta =
<ns:nextSourceResponse xmlns:ns="http://carbon.bbva.gtko.co">
<ns:return xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ax2431="http://vo.carbon.bbva.gtko.co/xsd"
xsi:type="ax2431:Automatizacion"> <ax2431:filename1>28189133_AltaLigerao_Oficina_cmarguello_20160408102300_N.txt</ax2431:filename1><ax2431:filename2>28189133_AltaLigerao_Oficina_cmarguello_20160408102300_S.txt</ax2431:filename2>
<ax2431:modulo>ALTA_LIGERA</ax2431:modulo>
</ns:return>
</ns:nextSourceResponse>
So i need to know the values of filename1, filename2 and modulo
I try, with xpath, to log filename1 value but i cant do.
<property
expression="fn:concat('filename - ', $ctx:rta/ns:nextSourceResponse/ns:return/ax2431:filename1)"
name="filename1" scope="default" type="STRING" xmlns:ns="http://carbon.bbva.gtko.co" xmlns:ax2431="http://vo.carbon.bbva.gtko.co/xsd"/>
<log level="custom">
<property expression="get-property('filename1')" name="filename"
xmlns:ns="http://carbon.bbva.gtko.co" />
</log>
and the log:
`INFO - LogMediator filename = filename - `
i also try with the same result (same log)
´expression="fn:concat('filename - ', $ctx:rta/ax2431:filename1)"´
`expression="fn:concat('filename - ', $ctx:rta/filename1)"`
Whats the correct way to do that?
Thanks
Just a test:
<property expression="$body/*"
name="rta" scope="default" type="STRING" />
<log level="custom">
<property expression="$ctx:rta" name="Respuesta" />
</log>
<property expression="//ns:nextSourceResponse/ns:return/ax2431:filename1" name="Respuesta2" xmlns:ns="http://carbon.bbva.gtko.co" xmlns:ax2431="http://vo.carbon.bbva.gtko.co/xsd"/>
<property
expression="fn:concat('test - ', get-property('Respuesta2'))"
name="filename1" scope="default" type="STRING" xmlns:ns="http://carbon.bbva.gtko.co" xmlns:ax2431="http://vo.carbon.bbva.gtko.co/xsd"/>
<log level="custom">
<property expression="get-property('filename1')" name="filename"
xmlns:ns="http://carbon.bbva.gtko.co" />
</log>
The logs:
[2016-04-29 14:19:48,005] INFO - LogMediator Respuesta =
<ns:nextSourceResponse xmlns:ns="http://carbon.bbva.gtko.co"><ns:return xmlns:ax2431="http://vo.carbon.bbva.gtko.co/xsd" xmlns

If you want to use the $ctx:rta way, please use it like in this property:
<property expression="$ctx:rta//ns:return/ax2431:filename1/text()"
name="Respuesta2" xmlns:ns="http://carbon.bbva.gtko.co" xmlns:ax2431="http://vo.carbon.bbva.gtko.co/xsd"/>
Finally i can.
The request:
`<body>
<ns:nextSourceResponse xmlns:ns="http://carbon.bbva.gtko.co">
</ns:nextSourceResponse>
</body>`
The key is in the target:
`<callout action="nextSource" initAxis2ClientOptions="false"
serviceURL="http://192.168.0.33:9764/services/AltaLigeraService?wsdl">
<source type="envelope" />
<target xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:s12="http://www.w3.org/2003/05/soap-envelope"
xpath="s11:Body/child::*[fn:position()=1] | s12:Body/child::*[fn:position()=1]" />
</callout>`
after that i can access value of filename
`<property expression="//ns:nextSourceResponse/ns:return/ax2431:filename1"
name="filename1" scope="default" type="STRING"
xmlns:ax2431="http://vo.carbon.bbva.gtko.co/xsd" xmlns:ns="http://carbon.bbva.gtko.co" />`

I'm trying to develop a sequence in Wso2 esb. I need to log the URL of the endpoint
this a snippet of my sequence
<script language="js"><![CDATA[
var log = mc.getServiceLog();
var requestBody = mc.getProperty("requestBody");
log.info("Avant de checker l'adresse "+requestBody.city);
mc.setProperty("addressNonNull",1);
if (requestBody.street || requestBody.zip || requestBody.city || requestBody.country) {
if(requestBody.street) {
mc.setProperty("query.param.street",requestBody.street);
}
if(requestBody.city) {
mc.setProperty("query.param.city",requestBody.city);
}
mc.setProperty("addressNonNull",1);
}
log.info("crm_create_subtasks_v2 address_value ==>"+requestBody.street+"|" +requestBody.zip+"|"+requestBody.city);
]]>
</script>
<switch source="get-property('addressNonNull')" xmlns:ns="http://org.apache.synapse/xsd">
<case regex="1.0">
<header name="Content-Type" scope="transport" value="application/json"/>
<property name="Content-Encoding" action="remove" scope="transport"/>
<property name="Authorization" expression="fn:concat('Basic ', base64Encode('user:password'))" scope="transport" type="STRING" xmlns:ns="http://org.apache.synapse/xsd"/>
<call>
<endpoint key="jira_address_exist_v2"/>
</call>
<property expression="json-eval($.)" name="check address exist"
scope="default" type="STRING" xmlns:ns="http://org.apache.synapse/xsd"/>
<log>
<property name="create_subtasks_v2 response jira_address_exist_v2" expression="json-eval($.)"/>
</log>
I need to display URL generated befor making request to the endpoint "jira_address_exist_v2" in the logs.
Best regards
Add this just before the call mediator,
<log level="simple"/>
<call>
<endpoint key="jira_address_exist_v2"/>
</call>
Not sure if this works, but at least you can give it a try. Add the following just before .
<log level="full">
<property name="To" expression="$trp:To" />
<property name="TO" expression="$trp:TO" />
</log>
If this doesn't work you can also enable wire log. Go to the esb console -> confiugre -> logging and search for a class xxx.http.wire and enable debug. Then you'll see what the esb receives and sends out.
I have a proxy service to search a user in multiple systems and should return the combined responses in JSON format.I get the responses combined but instead of getting it in JSON format I get the responses in XML format.
I can see JSON responses in WSO2 server logs as below:

Please let me know how I can get the JSON response.
Any help would be greatly appreciated.
You can set the messageType to application/json instead of application/xacml+json in outSequence and try.
<property name="messageType" value="application/json" scope="axis2" type="STRING" description="messageType"/>
Also there is no application/xacml+json message formatters and message builders shipped with WSO2 ESB by default. If you need to use these formats you have to write your own formatters and builders and configure them in axis2.xml file.
Below is the proxy implemented in WSO2 ESB 4.8.1, this return response in binary format as shown next to the proxy code. Response is expected in the xml response.
Note: This proxy returns xml response in WSO2 ESB 4.9.0 as expected.

To convert an XML payload to JSON, set the messageType property to application/json in the axis2 scope before sending message to an endpoint.
<property name="messageType" value="application/json" scope="axis2"/>
I am not sure why you only have inSequence .
And you are logging both before and after call content inside inSequence.
Can you use outSequence and check ? i.e
<outSequence>
<property name="messageType" value="application/json" scope="axis2"/>
<send/>
</outSequence>
Please check that you have enabled the binary message builder/formatter in /repository/conf/axis2/axis2.xml. If so, disable binary message builder and use default message builders/formatters and try this again.

You can use an enrich mediator to remove jsonObject from response body like below.
<enrich>
<source clone="true" xpath="$body//jsonObject//ResponseJSON"/>
<target type="body"/>
</enrich>
You can add a log mediator after enrich mediator and check the changed body.
Hope this will help you.
In side ESB mediator communications take place as SOAP messages. when you send JSON request or when ESB received JSON response what ESB does in convert that to xml / soap message by adding tag to prevent multi rooted xml.
try to use
<property name="messageType" value="application/json" scope="axis2"/>
before send / call. this will automatically remove your jsonObject from response. but if you want to convert response to xml from json then you need to manually modify using enrich mediator
make sure json formatter enabled in axis2.xml
In WSO2 ESB, I have created an rest API. This API needs to connect to two different services, and combine the results.
For this, I use an API, with in de insequence a clone mediator that sends out the appropriate messages. This works fine.
In the outsequence, I use a logger to see the incoming messages. Both are json and come back ok. I then want to use an aggregate mediator to combine the two. With this, I have two issues:
when using a rootElementProperty to place the two items under one parent, a NPE happens,
when using enrich mediators or whatever else to make a correct message, and ending with send, the resulting message is never sent back.
What can be the cause of this?
This is the actual API:

<api xmlns="http://ws.apache.org/ns/synapse" name="Cale-StreetsAPI" context="/Cale-StreetsAPI">
<resource methods="GET" uri-template="/getStreets?lat={lat}&lon={lon}&radius={radius}">
<inSequence>
<property name="aggRoot" scope="default">
<red:jsonObject xmlns:red="redora"/>
</property>
<log description="">
<property name="lat" expression="get-property('uri.var.lat')"/>
<property name="lon" expression="get-property('uri.var.lon')"/>
<property name="radius" expression="get-property('uri.var.radius')"/>
</log>
<clone continueParent="true" id="deCartaStreets">

I faced the same problem you did. According to number of posts over Internet APIs doesn't support aggregation.
So my solution was to introduce aggregating Proxy service which did all the job where API just made a call to that proxy service.
So if you modify your solution as follows you should be able to achieve what you expect:
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="AggregatingProxy" transports="local https http" startOnLoad="true" trace="disable">
<target>
<inSequence>
<log level="full"/>
<property name="enclosing_element">
<result xmlns=""/>
</property>
<clone continueParent="true">
<property name="aggRoot" scope="default">
<red:jsonObject xmlns:red="redora"/>
</property>
<log description="">
<property name="lat" expression="get-property('uri.var.lat')"/>
<property name="lon" expression="get-property('uri.var.lon')"/>
<property name="radius" expression="get-property('uri.var.radius')"/>
</log>
<clone continueParent="true" id="deCartaStreets">
<target>
<sequence>
<sequence key="DeCartaDDS"/>
</sequence>
</target>
<target>
<sequence>
<sequence key="DeCartaReverseGeo"/>
</sequence>
</target>
</clone>
</clone>
</inSequence>
<outSequence>
<property name="messageType" value="application/xml" scope="axis2" type="STRING" description="messageType"/>
<log level="full" description="">
<property name="WSANSWER" value="true"/>
</log>
<aggregate>
<completeCondition>
<messageCount min="2" max="-1"/>
</completeCondition>
<onComplete expression="$body/jsonObject">
<enrich>
<source clone="true" xpath="$body//jsonObject"/>
<target type="property" property="ResultItems"/>
</enrich>
<log level="custom">
<property name="ResultItems" expression="get-property('ResultItems')"/>
</log>
<enrich>
<source type="inline" clone="true">
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header/>
<soapenv:Body>
<JsonResponse xmlns="dummy"/>
</soapenv:Body>
</soapenv:Envelope>
</source>
<target type="envelope"/>
</enrich>
<enrich>
<source type="property" clone="true" property="ResultItems"/>
<target xmlns:red="dummy" action="child" xpath="//red:JsonResponse"/>
</enrich>
<log level="full" description="">
<property name="AGGREGATE_END" value="true"/>
</log>
<property name="messageType" value="application/json" scope="axis2" type="STRING" description="messageType"/>
<send/>
</onComplete>
</aggregate>
</outSequence>
<faultSequence>
<log level="full" category="WARN"/>
</faultSequence>
</target>
</proxy>
API Configuration:
<api xmlns="http://ws.apache.org/ns/synapse" name="Cale-StreetsAPI" context="/Cale-StreetsAPI">
<resource methods="GET" uri-template="/getStreets?lat={lat}&lon={lon}&radius={radius}">
<inSequence>
<call>
<endpoint>
<address uri="http://localhost:8280/services/AggregatingProxy" format="soap12"></address>
</endpoint>
</call>
<respond/>
</inSequence>
</resource>
</api>
This actually worked out for me and hopefully will help you too.
Also consider using:
<property name="enclosing_element">
<result xmlns=""/>
</property>
...
<onComplete expression="$body/jsonObject" enclosingElementProperty="enclosing_element">
In case your service return different type of results.
Thanks,
Vladimir.
