I have created a Resful WebApplication and upload it in wso2 as a Restful Service
I want to call this RestFul Service using a proxy service in wso,Is it possible
While doing this ,i am not able to get the response
Below is my Proxy Service configuration
<?xml version="1.0" encoding="UTF-8"?><proxy xmlns="http://ws.apache.org/ns/synapse" name="ProxyService" transports="https,http" statistics="disable" trace="disable" startOnLoad="true">
<target>
<outSequence>
<send/>
</outSequence>
<endpoint>
<http method="get" uri-template="http://10.132.97.131:9763/JerseyJSONExample/rest/jsonServices/print/mahi/"/>
</endpoint>
</target>

But while calling this proxy service,i am not able to get the response
If i am simply calling the service
http://10.132.97.131:9763/JerseyJSONExample/rest/jsonServices/print/mahi/
I am getting the response...
Can anyone help me on this what actually is the problem
You can use the following configuration to call a restful service from proxy service
<inSequence>
<property name="HTTP_METHOD" value="GET" scope="axis2" type="STRING"/>
<send>
<endpoint>
<address uri="http://10.132.97.131:9763/JerseyJSONExample/rest/jsonServices/print/mahi/"
format="pox"/></endpoint>
</send>
</inSequence>

I've created JMS sender in WSO2 ESB 4.9.0 as below and configured JMS sender in axis2.xml file. I'm getting the below exception when I run the proxy service. Using Websphere MQ JMS queues.
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="StockQuoteProxy"
transports="http"

javax.naming.NameNotFoundException: Name [dynamicQueues/myqueue] is not bound in this Context. Unable to find [dynamicQueues]
In my scenario using the WSO2 MB, the correct endpoint it´s this:
<address uri="jms:/MyQueue?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.wso2.andes.jndi.PropertiesFileInitialContextFactory&java.naming.provider.url=repository/conf/jndi.properties&transport.jms.DestinationType=queue"/>
Your proxy config use:
<property name="OUT_ONLY" value="true"/>
So, no response is sent to the client.
You need to specify a WSDL in the proxy config with an operation that does not have a response message or return a status = 200 with:
<property name="FORCE_SC_ACCEPTED" value="true" scope="axis2"/>
this is what I thought would be a fairly straight-forward service chaining scenario.
All I want to do it forward some data to a proxy service, that proxy service will then iterate over the data and use an ID ("entity_id") from that data (which it can successfully retrieve) to look up a resource sitting in WSO2 Data Services Server. Once it has the result of that request, I want to forward it to another application (RequestBin, in this case).
Please take a look at my proxy configuration below:
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="pollService"
transports="https,http"
statistics="disable"
trace="disable"

<iterate id="iter1"

<target sequence="anon">

<log level="full"/>
<property name="uri.var.entityid" expression="//*[local-name()='entity_id']"/>
<call>
<endpoint>

uri-template="http://54.66.155.36:9764/services/civicrm/activity/{uri.var.entityid}"/>
</endpoint>
</call>
<log level="full"/>
<call>
<endpoint>
<http method="post" uri-template="http://requestb.in/1c79v711"/>
</endpoint>
</call>
<log level="full"/>
</sequence>

I currently do not get any indication that those two calls have fired at all.
Any assistance would be greatly appreciated.
Thank you.
you can enable the wirelog and verify whether calls have fired or not.
please refer the following blog post to learn about wirelog.

Could you also give a sample message (what is going into the proxy) , and to see a finer-grain detail of what is going on in your proxy , go into [esb-home]/repository/conf/ and open the log4j.properties file , and set
log4j.category.org.apache.synapse=DEBUG , also do as #robin suggested. Try putting
<log level="full" category="DEBUG" separator="-----:-----"/>
in your proxy where you want to see the state of the message at that point.
how I can call web service inside of proxy? Proxy itself works fine, and I added call of logging web service in "in" sequence. I create call using payload factory + send.
Problem is, that proxy now returns result of this logging web service instead of
what web service should return. There is address end point defined in "out" sequence.
I am using WSO2 ESB 4.6.0.
This is the simple example of calling web service inside of the proxy. You need to up back-end service before create the proxy
<proxy xmlns="http://ws.apache.org/ns/synapse" name="customPro" transports="https,http" statistics="disable" trace="disable" startOnLoad="true">
<target>
<inSequence>
<send>
<endpoint>
<address uri="http://localhost:9000/services/SimpleStockQuoteService"/>
</endpoint>
</send>
</inSequence>
<out-sequence>
<send/>
</outSequence>
</target>
<publishWSDL uri="http://localhost:9000/services/SimpleStockQuoteService?wsdl"/>

You need to define web service url within the end-point in tag
As well as, this kind of send mediator return end-point response to outSequence
by default.
You can get good understanding of these if you go through the ESB documentation from following url
http://docs.wso2.org/display/ESB460/Samples
If you need further help, feel free to ask here
There are two ways you can achieve the logs
1. Log ESB incoming and outgoing messages through wire log.
To enable debug mode for wire logs;
- ESB console > Configure > Logging
- Set “org.apache.synapse.transport.http.wire” level to “DEBUG”.
In the log, it indicates >> incoming messages to ESB
<< outgoing messages from ESB
2. Use Logs at the appropriate place
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="TestProxy"
transports="https,http"
statistics="disable"
trace="disable"
startOnLoad="true">
<target>
<inSequence>
<log level="full">
<property name="test" value="incomming to ESB-----------------------"/>
</log>
<send>
<endpoint>
<address uri="http://localhost:9000/services/SimpleStockQuoteService"/>
</endpoint>
</send>
<log level="full">
<property name="test" value="outcomming from ESB-----------------------"/>
</log>
</inSequence>
<outSequence>
<log level="full">

</log>
<send/>
<log level="full">

</log>

I've configured a proxy service to run some XSBRL validation stuff that accepts a get request amd return XML validation results. Here's proxy service configuration:
<proxy xmlns="http://ws.apache.org/ns/synapse" name="XBRLValidationRESTService" transports="https,http" statistics="disable" trace="disable" startOnLoad="true">
<target>
<inSequence>
<log level="full"/>
<property name="REST_URL_POSTFIX" value="/example.xbrl/validation/xbrl?media=xml" scope="axis2"/>
<property name="HTTP_METHOD" value="GET" scope="axis2"/>
<send>
<endpoint>
<address uri="http://localhost:10000/rest/xbrl" format="pox"/>
</endpoint>
</send>
</inSequence>
<outSequence>
<log level="full"/>
<send/>
</outSequence>
</target>

In the log file I can see that the underlying service responds with expected response, however the client receives nothing back because ESB fails with NPE for some reason.
Request used from localhost:
curl -k https://localhost:9443/services/XBRLValidationRESTService
Full log: http://pastebin.com/A5jB9wMF
What is the potential reason for that and how that could be fixed.
Thanks,
Vladimir.
Do you run ESB with blocking transport? By default esb uses NIO transport and the port is 8280. your proxy service url, will be;
http://localhost:8280/services/XBRLValidationRESTService
Rather putting log full state, use descriptive logs to identify message paths,
I'm new to this area and i need to access my web service via the ESB. as it mentioned in here - Service Mediation Using Proxy Services i tried to to create it. after that i run it and get the response as follows :
<TryitProxyError xmlns:h="http://wso2.org/ns/TryitProxy"
h:status="SOAP envelope error">org.apache.axis2.AxisFault:
The input stream for an incoming message is null.</TryitProxyError>
but i tried to run same web method using SOAPUi and get the expected out put as below:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<getPatientHistoryResponse xmlns="http://tilani.lk/">
<getPatientHistoryResult>
<NIC>123</NIC>
<FullName>ABC DEF</FullName>
<FirstName>ABC</FirstName>
<Surname>DEF</Surname>
<Title>Mr.</Title>
<Gender>M/Gender>
</getPatientHistoryResult>
</getPatientHistoryResponse>
</soap:Body>
</soap:Envelope>
what is the reason for this? i created this using .net
my WSDL Address - http://localhost:2935/PatientRegService.asmx?WSDL
then in
Define Endpoint as - http://localhost:2935/PatientRegService.asmx
EDIT
my proxy configuration is as follows:
<proxy xmlns="http://ws.apache.org/ns/synapse" name="PatientManagement" transports="https,http" statistics="disable" trace="disable" startOnLoad="true">
<target>
<outSequence>
<send/>
</outSequence>
<endpoint>
<address uri="http://localhost:2935/PatientRegService.asmx?WSDL"/>
</endpoint>
</target>
<publishWSDL uri="http://localhost:2935/PatientRegService.asmx?WSDL"/>

If you just want to access your web service via ESB you need to create a proxy service and access the proxy service URI instead of the original service URI. Just follow the Pass Through Proxy example.
Try the following proxy and see waht you are getting. Add this proxy configuration via source view editor.
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="testProxy"
transports="https http"
startOnLoad="true"
trace="disable">
<description/>
<target>
<inSequence>
<log level="full">
<property name="testprop" value="incoming message"/>
</log>
<send>
<endpoint>
<address uri="http://localhost:2935/PatientRegService.asmx"/>
</endpoint>
</send>
</inSequence>
<outSequence>
<send/>
</outSequence>
</target>
</proxy>
