I want to got the text/plain with wso2 vfs transport, is there any issue with the code or some configuration I have to check?thanks~

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.
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"

scope="transport"/>
<send>
<endpoint>
<address uri="vfs:file:////home/user/to"/>
</endpoint>
</send>
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.
Having trouble getting the database target for NLog to work. I have 2 targets: FILE and DB.. here is my NLog.config:
<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
autoReload="true"
throwExceptions="false">
<variable name="appName" value="KoreCMS" />
<targets async="true">
<target xsi:type="File"

layout="${longdate} - ${level:uppercase=true}: ${message}${onexception:${newline}EXCEPTION\: ${exception:format=ToString}}"
fileName="${basedir}\App_Data\Log\Debug.log"
keepFileOpen="false"
archiveFileName="${basedir}\App_Data\Log\Debug_${shortdate}.{##}.log"
archiveNumbering="Sequence"
archiveEvery="Day"
maxArchiveFiles="30"/>
<target xsi:type="Database"
name="database"
keepConnection="true"
useTransactions="true"
dbProvider="System.Data.SqlClient"
connectionStringName="DefaultConnection"
commandText="INSERT INTO Kore_Log(EventDateTime, EventLevel, UserName, MachineName, EventMessage, ErrorSource, ErrorClass, ErrorMethod, ErrorMessage, InnerErrorMessage) VALUES (#EventDateTime, #EventLevel, #UserName, #MachineName, #EventMessage, #ErrorSource, #ErrorClass, #ErrorMethod, #ErrorMessage, #InnerErrorMessage)">
<parameter name="#EventDateTime" layout="${date:s}" />
<parameter name="#EventLevel" layout="${level}" />
<parameter name="#UserName" layout="${aspnet-user-identity}" />
<parameter name="#MachineName" layout="${machinename}" />
<parameter name="#EventMessage" layout="${message}" />
<parameter name="#ErrorSource" layout="${event-context:item=error-source}" />
<parameter name="#ErrorClass" layout="${event-context:item=error-class}" />
<parameter name="#ErrorMethod" layout="${event-context:item=error-method}" />
<parameter name="#ErrorMessage" layout="${event-context:item=error-message}" />
<parameter name="#InnerErrorMessage" layout="${event-context:item=inner-error-message}" />
</target>
</targets>
<rules>
<logger name="*" writeTo="default" minlevel="Info" />
<logger name="*" writeTo="database" minlevel="Info" />
</rules>
</nlog>
And here is the DB design:
And here is the connection string:
<connectionStrings>
<add name="DefaultConnection" connectionString="Server=.\SQLExpress2012;Initial Catalog=MyDatabaseName;Integrated Security=True;Persist Security Info=True;MultipleActiveResultSets=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
What am I missing?
Alright, I figured it out... When I opened up SQL Profiler, I could see the INSERT command was indeed being sent, so I attempted to run the same command myself manually and discovered that I was being an idiot; basically, my Id column is setup as a uniqueidentifier and so of course it could not be auto incremented. The solution was to change the commandText in the Nlog.config to the following:
commandText="INSERT INTO Kore_Log(Id, EventDateTime, EventLevel, UserName, MachineName, EventMessage, ErrorSource, ErrorClass, ErrorMethod, ErrorMessage, InnerErrorMessage) VALUES (NEWID(), #EventDateTime, #EventLevel, #UserName, #MachineName, #EventMessage, #ErrorSource, #ErrorClass, #ErrorMethod, #ErrorMessage, #InnerErrorMessage)">
I got into same problem, reason was dbProvider value and connectionStringName key in nlog.config. I got it from here
<target name="database" xsi:type="Database" connectionString="${configsetting:name=sqlconnection.connectionString}"
dbProvider="Microsoft.Data.SqlClient.SqlConnection, Microsoft.Data.SqlClient">
Also,
connectionString should be used in place of connectionStringName
if Microsoft.Data.SqlClient is not added in dependency, it need to be added either using nuget package manager or manually.
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 :(

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
