WSO2 ESB send to multiple endpoints - wso2

Can a message be sent to multiple endpoints from within the send mediator in a proxy service?
This link from the WSO2 ESB Send Mediator documentation says under the Syntax chapter that If the message is to be sent to one or more endpoints, then the following is used:
<send>
(endpointref | endpoint)+
</send>
where the endpointref token refers to the following:
<endpoint key="name"/>
I've tried to include two endpoints under send, but the second one gets removed automatically when saving the proxy service (inside the Developer Studio or straight in the ESB Stratos interface). I did go to the Synapse page for the Send Mediator to see if they say anything special and their format says:
(endpointref | endpoint)?
Now assuming these characters represent regular expression, ? stands for 0 or 1 times, + is 1 or more times. Did WSO2 implement this extra "one or more endpoints" feature on top of Synapse Send Mediator or is it just a mistake on the documentation pages. If they did, what's the exact syntax to make it work?
Thank you!

Actually you can use Recipienlist endpoint to send a single message to multiple endpoints.
After defining recipient list store taht as localentry and provide that as endpoint key.

You can do something like this:
<send>
<endpoint key="jmsMBendpoint1"/>
</send>
<send>
<endpoint key="jmsMBendpoint2"/>
</send>
.I have used this approach and is working for me.

You can use the clone mediator to send to multiple endpoints with specifying respective endpoints as in the below configuration.
<sequence xmlns="http://ws.apache.org/ns/synapse" name="send_to_all">
<clone sequential="false">
<target endpoint="endpoint1"/>
<target endpoint="endpoint2"/>
<target endpoint="endpoint3"/>
</clone>
<drop/>
</sequence>

WSO2: Remove MQRFH2 header from outgoing IBM MQ message

I am facing an issue where the receiving application (consumer/listener of an IBM MQ) cannot handle MQHRF2 format and is expecting the raw MQSTR format instead.
When put a plain old XML message into the queue using WSO2 Integrator (v. 6.1.1), the receiving application sees:
RFH € zMQSTR z <mcd><Msd>jms_text</Msd></mcd> X<jms>
<Dst>queue://QUEUE_ALIAS</Dst><Tms>1532002363544</Tms><Dlv>2</Dlv></jms>
ahead of my XML message which starts right after the JMS tag.
How can I force WSO2 to put MQSTR instead of MQRFH2 into the Websphere MQ? I have tried the following property just before sending via my endpoint but it has no effect.
<property name="JMS_IBM_FORMAT" value="MQSTR" scope="transport" type="STRING" action="set"/>
<send>
<endpoint key="conf:/endpoints/MY_ENDPOINT.xml"/>
</send>
The endpoint is merely defined as:
<endpoint name="MY_ENDPOINT" xmlns="http://ws.apache.org/ns/synapse">
<address format="pox" uri="jms://QUEUE_ALIAS"/>
</endpoint>
The RFH2 header is added by MQ. If you don't need it, add targetClient=1 to the location URI, like:
queue:///MYQUEUE?targetClient=1
http://www.mqseries.net/phpBB2/viewtopic.php?=&p=171236
Change the queue definition the application gets from as follows:-
ALTER QLOCAL(q-name) PROPCTL(NONE)

What exactly does this WSO2 ESB echo endpoint?

I am very new in WSO2 and I have the following doubt related to an ESB project on which I am working.
In this ESB application I am sending a message to a named endopoint mediator, something like this:
<send>
<endpoint key="echoEndpoint"/>
</send>
This is the contend of the related echoEndpoint.xml file in my project:
<?xml version="1.0" encoding="UTF-8"?>
<endpoint name="echoEndpoint" xmlns="http://ws.apache.org/ns/synapse">
<address format="soap11" statistics="enable" trace="enable" uri="http://localhost:8280/services/echo"/>
</endpoint>
So what exactly does this endpoint? The http://localhost:8280/services/echo is something like a predefined endopoined provided natively by WSO2? or what?
echo service included into esb/ei by default. You can see it in Carbon Panel -> Main -> Manage -> Services. There you can test it via "Try It" feature. It has few methods:
echoInt extected to get integer as argument and returned same integer value
echoString - expected to get string value as argument and returned same value
echoOMElement - received XML as argument and returned same XML
and some other methods. General idea - this service returned same value as it is received.
This service is helpful for testing purposes.
This is a service that by default is already displayed when you run the ESB. Echo.aar is located in the path repository\deployment\server\axis2services . And wsdl you can see https://localhost:your_Port/services/echo?wsdl

WSO2 Developing Custom Endpoint

i need to extend the LoadBalance Endpoint developing my custom endpoint.
I tried:
1)
public class CustomLoadBalanceEndpoint extends LoadbalanceEndpoint
2) i exported it using wso2 studio in the /repository/components/dropins folder
3) i cannot find the way to use it inside ESB... I tried with this code
<endpoint class="it.innovapuglia.sistemapuglia.wso2.enpoint.CustomLoadBalanceEndpoint"
algorithm="org.apache.synapse.endpoints.algorithms.RoundRobin">
<endpoint name="tomcat1">
<address uri="http://localhost:8080/RestService/rest/servizio"/>
</endpoint>
</endpoint>
but ESB doesn't accept it saying me "Proxy service requires a valid in sequence or a valid endpoint."
You can not use your endpoint like that.
After developing your custom endpoint keep that in the repository/components/lib folder.You have to call your endpoint like this;
<endpoint name="CustomEndpoint">
<class name="org.wso2.carbon.endpoint.CustomLoadBalanceEndpoint">
</class>
</endpoint>
Check the following posts on how to add your custom endpoint concepts.

WSO2 indirect Endpoint inside Failover Group

Is it possible to use an Indirect Enpoint inside the definition of a Failover Group endpoint?
I mean something like this:
<endpoint xmlns="http://ws.apache.org/ns/synapse" name="failOver2">
<failover>
<endpoint key="LBEndpoint" />
</failover>
</endpoint>
Where LBEndpoint is a load balance endpoint defined and saved previously in the registry.
When i click on the Save button... all my configuration is lost and the fail over group comes back into this form:
<endpoint xmlns="http://ws.apache.org/ns/synapse" name="failOver2">
<failover/>
</endpoint>
Is this a bug? Inside the WSO2 ESB documentation it says that all this is possible.
Can you try editing synapse configuration directly? That is, not using sequence editor UI. Go to sourceview and manually edit and point the endpoint key in failoverendpoint.

WSO2 soap12 endpoint to soap11 external service

I create a simple WSDL proxy in WSO2 to allow Soap 1.2 enabled applications to work with Soap 1.1 only external web service. Everything is fine except WSO2 doesn't transform soap11 replies back to soap12 when I send request via Soap12 WSO endpoint.
<proxy xmlns="http://ws.apache.org/ns/synapse" name="MySOAP" transports="http"
statistics="disable" trace="disable" startOnLoad="true">
<target>
<endpoint>
<wsdl service="ExtService" port="ExtPort" uri="https://my.local/wsdl/current
/ExtService.wsdl"/>
<property name="DISABLE_CHUNKING" value="true" scope="axis2"/>
</endpoint>
</target>
<publishWSDL uri="file:///home/sysadmin/MySOAP.wsdl"/>
<description></description>
</proxy>
Has anybody faced anything similar? WSO2 ESB version 4.6.0
You need to add the format as following.
<endpoint>
<address uri="http://localhost:9000/services/SimpleStockQuoteService" format="soap11" />
</endpoint>
Format - The message format for the endpoint. The available values are:
[format="soap11|soap12|pox|get"]
Leave As-Is - No transformation is done to the outgoing message.
SOAP 1.1 - Transforming message to SOAP 1.1.
SOAP 1.2 - Transforming message to SOAP 1.2.
Plain Old XML (POX) - Transforming to plain old XML format
Representational State Transfer (REST) - Transforming to HTTP Get
Request
GET
http://docs.wso2.org/wiki/display/ESB460/Default+Endpoint
This has been an issue for a while now. See jira https://wso2.org/jira/browse/ESBJAVA-1994.
If you don't want to manually transform your response from the backend, uncomment the relevant NHTTP transport entries in axis2.xml and comment out the HTTP PassThrough transport entries.
