When I try to send a soap request to my web service from wso2ei I got this error:
If I call direct the proxy or web service, everything is fine, seams is something with send mediator, but I cant figure out! Even if I change the code to call direct the web service by endpoint the error is the same.

I just found some interesting behavior. If I change wsdl-endpoint by an address-endpoint the API works. I added a payloadFactory to create a restResponse and some logs.
What I still dont know is why wsdl-endpoint doesnt work or what I should change to make it works.

I think I´ve found something. I can use wsdl-endpoint tag if I send it direct to tomcat´s web server, if I access my web service through a wso2´s proxy, address-endpoint must be the choice.
I dont have any explanation why, but that´s wso2 behavior so far.

You can refer to the following blog regarding the Using OAuth2 Protected Back-ends With API Manager., This blog is regarding handling that in the WSO2 API Manager. But this is applicable in the EI as well.
[1] https://medium.com/#menakajayawardena/wso2-how-to-using-oauth2-protected-back-ends-with-api-manager-5d7e234c61c
I've created an RESTful API in wso2-am 2.0.0. But I'm face a problem and a would some help.
I have a resource wiht GET http method which receive an url param and I made a SOAP payload to send via POST to backend (backend is soap11).
For this, I used a custom 'in' sequence:
<?xml version="1.0" encoding="UTF-8"?>
<sequence name="JSONtoSOAP" trace="disable"
xmlns="http://ws.apache.org/ns/synapse">
<log description="Entrada" level="full" separator=",">
<property expression="get-property('uri.var.cpfCnpj')" name="cpfcnpj" />
<property name="trace"
value="IN LOG" />
</log>
<property name="HTTP_METHOD" value="POST" scope="axis2" type="STRING" />
<property name="messageType" scope="axis2" type="STRING"
value="application/soap+xml" />
<enrich>
<source type="inline">
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body />
</soap:Envelope>
</source>
<target action="replace" type="envelope" />
</enrich>
<payloadFactory media-type="xml">
<format>
<man:QueryCustomerDetailsRequestMessage
xmlns:man="http://www.algartelecom.com.br/SOA/Service/ManageCustomerInformationPortalClientesReqCS">
<man:documentNumber>$1</man:documentNumber>
<man:tagetCRM />
</man:QueryCustomerDetailsRequestMessage>
</format>
<args>
<arg evaluator="xml" expression="get-property('uri.var.cpfCnpj')" />
</args>
</payloadFactory>
<property name="REST_URL_POSTFIX" value="" scope="axis2" />
<header name="Action" scope="default" value="queryCustomerDetails" />
<log description="Saida" level="full" separator=",">
<property name="trace" value="DEBUG LOG" />
</log>
</sequence>
Until here, without problem.
But when I try to call the resource from any restClient (SOAPui for example or wso2-am store) result in Runtime exception, like this:
<?xml version='1.0' encoding='UTF-8'?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<am:fault xmlns:am="http://wso2.org/apimanager">
<am:code/>
<am:type>Status report</am:type>
<am:message>Runtime Error</am:message>
<am:description/>
</am:fault>
</soap:Body>
</soap:Envelope>
Note that code and description tags are empty, and when I checked the server's log I found:
[2016-09-30 16:53:44,603] INFO - LogMediator STATUS = Executing default 'fault' sequence, ERROR_CODE = null, ERROR_MESSAGE = null
This is the correct way to produces a restful API and call a SOAP backend?
Anybody knows about this issue? (I believe, this feature works on WSO2 ESB).
You can try the following:
In the publisher, set your endpoint type to HTTP/SOAP endpoint
In your sequence don't set the REST_URL_POSTFIX to "", but remove the property completely
I need to check each file in directory "/home/user/from/" with com.wso2esb.command.MyCommand and if the result == true, replace file to "home/user/to/". I have the following proxy:

I can see the string "===555=== true" in the log file, it means that com.fx.FileIsOBI == true. But my file wasn't moved to "/home/user/to/". I think the problem is in
<property name="OUT_ONLY" value="true" scope="default"/>
<property xmlns:ns="http://org.apache.synapse/xsd"
xmlns:ns3="http://org.apache.synapse/xsd"
name="transport.vfs.ReplyFileName"

<send>
<endpoint>
<address uri="vfs:file:////home/user/to"/>

What's wrong?
Please check if VFS transport is enabled,
https://docs.wso2.com/display/ESB490/VFS+Transport

I think there is an issue in your file path. Could you change it as below.
<parameter name="transport.vfs.FileURI">vfs:file:///home/user/from/</parameter>
<send>
<endpoint>
<address uri="vfs:file:///home/user/to"/>
</endpoint>
</send>
More over since you are processing an xml file change the content type as follows.
<parameter name="transport.vfs.FileNamePattern">.*\.xml</parameter>
<parameter name="transport.vfs.ContentType">text/xml</parameter>
Do these suggested changes and let us know your feedback.
I want to download an XML file from a Web site using WSO2 ESB. Assume that the URL is static for the sake of simplicity.
I have tried VFS both as a proxy service and an individual sequence without success, and couldn't find any relevant material on the Internet.
Here is the sequence XML:
<sequence xmlns="http://ws.apache.org/ns/synapse" name="download">
<in>
<log level="headers">
<property name="?" value="[download] in: started"/>
</log>
<property name="OUT_ONLY" value="true" scope="default" type="STRING"/>
<property name="transport.vfs.ContentType" value="text/xml" scope="transport" type="STRING"/>
<property name="transport.vfs.FileURI" value="http://static.nvd.nist.gov/feeds/xml/cve/nvdcve-2.0-2013.xml" scope="transport" type="STRING"/>
<log level="headers">
<property name="?" value="[download] in: sending over vfs"/>
</log>
<send>
<endpoint>
<address uri="http://static.nvd.nist.gov/feeds/xml/cve/nvdcve-2.0-2013.xml"/>
</endpoint>
</send>
<log level="headers">
<property name="?" value="[download] in: ended"/>
</log>
</in>
<out>
<log level="headers">
<property name="?" value="[download] out: started"/>
</log>
<send/>
<log level="headers">
<property name="?" value="[download] out: ended"/>
</log>
</out>
</sequence>
So, how to download a large file over HTTP with WSO2 ESB?
I have a similar problem, and by the moment I've solved it with an API and this code:
<api xmlns="http://ws.apache.org/ns/synapse" name="EcoRest" context="/services/ecorest">
<resource methods="GET" uri-template="/{idFile}">
<inSequence>
<send>
<endpoint>
<http method="get" uri-template="http://slx00012001:8888/repositoryfiles/{uri.var.idFile}">
<suspendOnFailure>
<errorCodes>101500,101510,101001,101000</errorCodes>
<initialDuration>10</initialDuration>
<progressionFactor>1.0</progressionFactor>
<maximumDuration>10</maximumDuration>
</suspendOnFailure>
</http>
</endpoint>
</send>
<property name="enableSwA" value="true" scope="axis2"></property>
</inSequence>
<faultSequence>
<log level="custom">
<property name="FAULT GETTING FILE" expression="get-property('uri.var.idFile')"></property>
</log>
<payloadFactory media-type="json">
<format> {"descError":"$1", "error": "true"} </format>
<args>
<arg evaluator="json" expression="$.descError"></arg>
</args>
</payloadFactory>
<property name="HTTP_SC" value="500" scope="axis2" type="STRING"></property>
<respond></respond>
</faultSequence>
</resource>
</api>
This API works perfectly and make a throught-pass with the files. But if I send an id_file doesn't exist, the backend service return an http 400 with a json-message, the process go into the faultsequence, but the payloadFactory in the faultsequence doesn't work, and I don't know why :(
Have a go with this configuration:
<proxy xmlns="http://ws.apache.org/ns/synapse" name="download" transports="https,http,vfs" statistics="disable" trace="disable" startOnLoad="true">
<target>
<inSequence>
<property name="OUT_ONLY" value="true" scope="default" type="STRING"/>
<property name="ClientApiNonBlocking" value="true" scope="axis2" action="remove"/>
<send>
<endpoint>
<address uri="vfs:file://home/secondary/file.xml"/>
</endpoint>
</send>
</inSequence>
</target>
<parameter name="transport.vfs.Streaming">true</parameter>
<parameter name="transport.vfs.FileURI">http://static.nvd.nist.gov/feeds/xml/cve/nvdcve-2.0-2013.xml</parameter>
<parameter name="transport.vfs.Locking">disable</parameter>
<description></description>
</proxy>
You can initiate the download using:
curl -v http://localhost:8280/services/download
You can find out more about the VFS Transport specific parameters here: http://docs.wso2.org/wiki/display/ESB460/VFS+Transport. You can also find another VFS example here: http://docs.wso2.org/wiki/pages/viewpage.action?pageId=16846489. Hope this helps.
I need write the response message to a "response.xml" file. And the response should be appended to this file, I set parameter "Append" true, but no use, is completely overwritten every time. Anyone can help me? Thanks and best regards.

Remove the append= true parameter from service level and use with endpoint url
eg:
vfs:file:///usr/local/wso2esb-4.0.3/Log?transport.vfs.Append=true
