Calling the service in a normal REST client i get the XML result withouth any problem.
The issue occured when the proxy tries to parse the resulting xml. Indeed removing the Log mediator with the property inside the proxy returns the result correctly.
What am i missing?
Add the following to your proxy:
<parameter name="ApplicationXMLBuilder.allowDTD">true</parameter>
Add the below parameter to the axis2.xml file under the <axisconfig name="AxisJava2.0"> also working.
<parameter name="ApplicationXMLBuilder.allowDTD">true</parameter>

I used wso2 esb 5.0 for create proxy services. I created proxy service using class mediator. Below is the java class.
public class CalculatePaymentAmount extends AbstractMediator {
public boolean mediate(MessageContext messageContext) {
String noOfMonths = messageContext.getEnvelope().getBody().getFirstElement().
getFirstChildWithName(new QName("noOfMonths")).getText();
String InsuranceRate = messageContext.getEnvelope().getBody().getFirstElement().
getFirstChildWithName(new QName("InsuranceRate")).getText();
DecimalFormat decimalFormat = new DecimalFormat("#.##");
double totalAmount = Double.parseDouble(noOfMonths) * Double.parseDouble(InsuranceRate);
messageContext.setProperty("noOfMonths", noOfMonths);
messageContext.setProperty("paymentAmount", decimalFormat.format(totalAmount));
return true;
}
public String getType() {
return null;
}
public void setTraceState(int traceState) {
traceState = 0;
}
public int getTraceState() {
return 0;
}
}
I created the proxy service using class mediator. Below define the proxy code.

This one working fine and gave expected response.
But when I use this class mediator with other mediators, it getting errors when I invoked the proxy service.

Can anyone help me to solve this. Any help or workarounds are really appreciated.
Your class mediator is accessing the elements 'noOfMonths' and 'InsuranceRate' from the message context. But according to the error log, the message context is having a different soap envelope which does not have the above elements.
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"><soapenv:Header xmlns:wsa="http://www.w3.org/2005/08/addressing"><wsa:Action>urn:getCertificateIDResponse</wsa:Action><wsa:RelatesTo>urn:uuid:6f4557eb-b8ff-4c19-bbe8-4c7e929d8386</wsa:RelatesTo></soapenv:Header><soapenv:Body><ns:getCertificateIDResponse xmlns:ns="http://sample.esb.org"><ns:return>-1250719063</ns:return></ns:getCertificateIDResponse></soapenv:Body></soapenv:Envelope>
This must me the response received from the call operation before the class mediator.
You have to either isolate the class mediator from the call operation and use different proxy services or move the class mediator above the payload factory.
For solve this issue, use payloadFactory mediator before the class mediator and set the parameters for the payload. I mentioned below the code.
<payloadFactory media-type="xml">
<format>
<paymentDetails xmlns="">
<noOfMonths>$1</noOfMonths>
<InsuranceRate>$2</InsuranceRate>
</paymentDetails>
</format>
<args>
<arg evaluator="xml" expression="get-property('default','noOfMonths')"/>
<arg evaluator="xml" expression="get-property('default','InsuranceRate')"/>
</args>
</payloadFactory>
<class name="com.mediator.java.CalculatePaymentAmount"/>
I need to send just one request (can be a proxy url) which takes user id as input and call multiple endpoints and return the response after aggregating all of them.
Currently I am using a proxy service implementation to achieve it but is returns just one response(can be from any of the endpoints) and not able to combine responses from other systems/endpoints. Though I can see the response from another endpoint in my server console.
Below is the code I implemented so far:

As we can see I get responses from both the endpoints in server logs.
As per analysis, I feel to make it work properly and get the responses from both the endpoints, we need change the following:
1. Using call mediator instead of send if we have multiple endpoints to be called.
2. Using enrich mediator to store the responses.
I tried following the above approaches but I am unable to get the expected results as I am not sure how to use enrich mediator in this case.
Please help me in fixing the above issues.
Clone mediator will be used to send identical copies of message to different endpoints.
Iterate mediator will be used to send message chunks of one particular message to different endpoints.
Enrich mediator will be used to change message (Ex: removing content, adding etc.) [1]
Check your endpoints and check whether they provide proper responses to work with aggregate mediator.
I add sample scenario here. You can test that with your ESB pack to understand the above three mediators usage. You just have to start 2 instances of SimpleStockQuote service [2] and publish message to proxy via SOAPUI.

I'm trying to use the message forwarding processor in WSO2 (4.8.1).
The context is the follow:
1) I've my messages in a Message Store
2) I use my message forwarding processor to extract messages from the store and invoke a wso2 proxy
3) my proxy invoke an external service
I'm testing the SOAP Fault of my external service.
Here you are my code
My message forwarding processor configuration is the following

I see that the execution doesn't cross in the message processor retry sequence and probably something goes wrong when i close the proxy out sequence.
Any suggestion? Thank you very much in advance!!!

When you send back the soap fault to the message processor in your proxy outSequence, the message processor execute it's fault sequence : HTTP Status code of your message must have a value different from '500'. You should log it (use property $axis2:HTTP_SC)
When the fault sequence is executed 'max.delivery.attempts' times, the message processor is deactivated, if you want it to redeliver the message indefinitely, set this value to -1
I've recently started experimenting with a Message exchange between WSO2 ESB's via WSO2's MB for a requirement. Created a JMS sender Proxy Service which concatenates endpoint URL based on SOAP Input (used Header property and defaultEndpoint).
On Message Broker:
Have set up a Hierarchical topic as
Root|
Node1
Node2
With 3 users and their specific roles as Root, Node1, Node2. Requirement is Node 1 should be able to subscribe for both Node 1 and Root, Similarly for Node2, Only Node2 and Root.
The problem is When creating a proxy service subscriber can only set it to subscribe one Node only (Root or Node1 or Node2). Tried setting destination as Root.# but then All Nodes are subscribed (even when Node USer is not set to Subscribe the other based on Role based Topic access). Following is the code for subscriber
enter code here

brokerlist='tcp://localhost:5680'
topic.Root = Root
topic.Root.Node1 = Root.Node1
topic.Root.Node2 = Root.Node2
Is there a way a Subscriber can subscribe to Multiple Topics in a hierrarchy and its access be controlled by User and Role?
I am trying to create a route that is determined by the content in the REST payload using xPath. I have been successful in using routing based on the message header:
<when>
<simple>${headers.operationName} == 'createContainerOutput'</simple>
<bean ref="containerOutputProcessor"/>
</when>
which properly invokes the containerOutputProcessor...
but for this xPath route:
<when>
<xpath>/*[local-name()='order-request']/#type='TrayOutput'</xpath>
<bean ref="containerOutputProcessor"/>
</when>
I get the the exception:
org.apache.camel.NoTypeConversionAvailableException: No type converter available to convert from type: org.apache.cxf.message.MessageContentsList to the required type: org.w3c.dom.Document with value [com.mmi.ws.ContainerOutputOrderRequest#6290dc]
for this payload
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<order-request type="TrayOutput">
<parameter name="orderName">Example Tray Output Order</parameter>
<parameter name="enableScan">true</parameter>
<parameter name="autoStart">false</parameter>
<parameter name="priority">3</parameter>
<item barcode="23990001"/>
<item barcode="23990002"/>
</order-request>
Is this type of routing a good idea? Is there a better way to route based on what type of order-request is being submitted?
Thanks for any help/guidance you may have for me!

Before the content based router, you can convert the message to take out the payload from the internal CXF list. There is a trick with the simple language to grab the first index from the list:
<transform>
<simple>${body[0]}</simple>
</transform>
<choice>
...
Do you have camel-jaxb on the classpath. If so it may work out of the box without that trick. Not sure though, as CXF is a bit special. Also dependes on what version of Camel / CXF you use. You should really mention this when you ask questions!
