use vfs in wso2 esb? - wso2

I create a proxy service that transform file new text document.txt from ///d:test/orginal
to ///d:test/pass in local
My proxy code is:
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="testVFS"
transports="https,http,local"
statistics="disable"

<outSequence>
<send/>
</outSequence>
<endpoint>
<address uri="https://127.0.0.1:9443/services/SimpleStockQuoteService?wsdl"/>
</endpoint>
</target>
<parameter name="transport.PollInterval">5</parameter>
<parameter name="transport.vfs.ActionAfterProcess">MOVE</parameter>
<parameter name="transport.vfs.FileURI">file:///D:/test/Orginal/</parameter>
<parameter name="transport.vfs.MoveAfterProcess">file:///D:/test/Pass/</parameter>

<parameter name="transport.vfs.FileNamePattern">.*.xml</parameter>
<parameter name="transport.vfs.ContentType">text/xml</parameter>
<parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter>

</proxy>
But I have an error and not transform files:
<TryitProxyError xmlns:h="http://wso2.org/ns/TryitProxy" h:status="SOAP envelope error">org.apache.axis2.AxisFault: Read timed out</TryitProxyError>
Thanks

In your proxy your transports are set as:
transports="https,http,local"
Changing this to
transports="vfs"
will ensure it tries to use the VFSTransportListener.
Just make sure that the following line is not commented in %ESB_HOME%\repository\conf\axis2\axis2.xml:
<transportReceiver class="org.apache.synapse.transport.vfs.VFSTransportListener" name="vfs"/>

You must use vfs transport. To understand how to use refer http://docs.wso2.org/display/ESB470/VFS+Transport and http://docs.wso2.org/pages/viewpage.action?pageId=26838852

The problem is related to the SoapAction endpoint.
Example using:
<header name="Action" value="urn:mediate"/>
<send>
<endpoint key="SimpleStockQuoteService"/>
</send>

Email receiver proxy in wso2 esb 5.0.0 is not working

I have created email receiver proxy in WSO2-ESB5.0, proxy is connecting to email box and and I am seeing text in the logs "Processing message # : 1 in same thread".
But nothing is getting printed in the body of the proxy where I am expecting proxy should read the email body and pass to insequence of the proxy.
And also emails are not MOVED OR DELETED when I set the properties ActionAfterProcess to MOVE/DELETE.
I see some issues here
you have in one hand
<parameter name="transport.mail.ActionAfterFailure">DELETE</parameter>
<parameter name="transport.mail.ActionAfterProcess">DELETE</parameter>
and on another hand you try to move to a folder after process or failure
<parameter name="transport.mail.MoveAfterFailure">Inbox/Failed</parameter>
<parameter name="transport.mail.MoveAfterProcess">Inbox/Processed</parameter>
So either you should remove all those four lines (default behaviour is "REMOVE") or change to
<parameter name="transport.mail.ActionAfterFailure">MOVE</parameter>
<parameter name="transport.mail.ActionAfterProcess">MOVE</parameter>
In order to move processed files
Fetch size sounds really small to me, could you try a higher value like
<parameter name="mail.imap.fetchsize">1024</parameter>
Then I assume Inbox/TestInbox is existing and you successfully connect to the mailbox. Are you sure that the message content type is application/xml (could you simply use plain/text for instance).
Could you also try
<property name="senderAddress" expression="get-property('transport', 'From')"/>
<log level="custom">
<property name="Sender Address" expression="get-property('senderAddress')"/>
</log>
To see if you can get the sender address.
Here is sample of my proxy:
<?xml version="1.0" encoding="UTF-8"?>

How to get message id in queue after call web-service in wso 2 esb

I am using wso2ESB Version 4.9.0
I have a problem. My proxy like:
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="InOnlyProxy"
transports="http,https"
statistics="disable"
trace="disable"

<target>
<inSequence>
<log level="full"/>
<log level="custom">
<property xmlns:ns="http://org.apache.synapse/xsd"
name="MESSAGE_ID_BOFORE"
expression="get-property('MessageID')"/>
</log>
<store messageStore="s2"/>
</inSequence>
</target>
<description/>
</proxy>
<messageProcessor name="Processor2" class="org.apache.synapse.message.processor.impl.forwarder.ScheduledMessageForwardingProcessor" targetEndpoint="EndPoint1" messageStore="s2" xmlns="http://ws.apache.org/ns/synapse">
<parameter name="interval">1000</parameter>
<parameter name="client.retry.interval">1000</parameter>
<parameter name="max.delivery.attempts">4</parameter>
<parameter name="message.processor.reply.sequence">replySequence</parameter>
<parameter name="is.active">true</parameter>
<parameter name="max.delivery.drop">Disabled</parameter>

</messageProcessor>
<?xml version="1.0" encoding="UTF-8"?>
<sequence name="replySequence" trace="enable" xmlns="http://ws.apache.org/ns/synapse">
<log level="full">
<property name="REPLY" value="MESSAGE"/>
</log>
<send/>
</sequence>
Suppose my web-service has a message_id parameter and when i call this web-service with message_id=10, the web-service return same message_id with 10.
So now i call web-service without message_id.
I want save a message in a queue and a messageProcessor call message in the queue. So i want a ID for identity message in replaySequence. I use message ID but message id before call is different after call. so can you help me for identity message response?
I want call another web-service in replaySequence using Message-id.
Thanks.

WSO2 ESB MailTransportListener not receiving

I just installed my brand new WSO2 ESB 4.9.0. This is the latest version which I downloaded yesterday.
I am trying to get my ESB to receive e-mail from a server. I have tried POP3 and IMAP. I have been using several references to help me(Since I am a new member, my reputation does not yet allow me to post proper links to all my references):
stackoverflow.com/questions/27376833/wso2-mailto-transport-emptied-my-inbox

irhamiqbal.wordpress.com/how-to-receive-email-using-wso2-esb/
jayalalk.blogspot.com/2014/06/wso2-esb-mail-sending-with-html-complex.html
And of course the official documentation:
https://docs.wso2.com/display/ESB481/MailTo+Transport
https://docs.wso2.com/display/AS501/Using+Mail+transport+to+Invoke+Web+Services
All of my reading leads me to believe that I have everything set up properly (or if not properly, good enough to get some error messages to troubleshoot).
I did restart the WSO2 ESB and the following message shows up in the console log:
TID[-1234] [ESB] [2016-08-02 21:45:37,237] INFO {org.apache.axis2.transport.mail.MailTransportListener} - MAILTO listener started
I get no other indication in the logs one way or another.
I edited (and double checked) my $CARBON_HOME/repository/conf/axis2/axis2.xml, and I'm pretty sure I have the mail transport enabled properly:
<transportReceiver name="mailto" class="org.apache.axis2.transport.mail.MailTransportListener">
<!-- configure any optional POP3/IMAP properties
check com.sun.mail.pop3 and com.sun.mail.imap package documentation for more details-->
</transportReceiver>
<transportSender name="mailto" class="org.apache.axis2.transport.mail.MailTransportSender">
<parameter name="mail.smtp.host">my.smtp.server</parameter>
<parameter name="mail.smtp.port">587</parameter>
<parameter name="mail.smtp.starttls.enable">false</parameter>
<parameter name="mail.smtp.auth">true</parameter>
<parameter name="mail.smtp.user">my#user.id</parameter>
<parameter name="mail.smtp.password">password</parameter>
<parameter name="mail.smtp.from">my#email.com</parameter>
</transportSender>
And, finally, I have my Proxy Service setup (in its current iteration, anyway):
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"

<parameter name="mail.pop3.port">995</parameter>
<parameter name="mail.pop3.socketFactory.fallback">false</parameter>
<description/>
</proxy>
With all of this, my question is: is there something else I am missing to get the ESB to at least attempt to retrieve e-mail? What bothers me is I am not getting any error messages to troubleshoot (such as my mail not being in plain test).
I tried the same scenario with a Gmail account and it works fine for me, seems like some mis-configuration in your POP server. You need to add following property as well.
<parameter name="transport.mail.ContentType">text/plain</parameter>
See the full proxy configs below.

<parameter name="mail.pop3.socketFactory.fallback">false</parameter>

Also if you need to further debug this you can enable DEBUG logs. To do this add the following line to repository/conf/log4j.properties and restart.
log4j.logger.org.apache.axis2.transport.mail.MailTransportListener=DEBUG

How to keep file after being processed in source folder vfs transport WSO2

I use VFS transport in WSO2 to route file from one folder to another. But now I'm facing a problem, I do not want to move the processed file to another folder or delete it. The problem is VFS transport has a default action DELETE or move processed file to another folder. Is it possible to keep the processed file in the source folder? Or do I have to change the code or modify something else? Is there any other way to do this?
FYI, my proxy looks like this,
<proxy name="XXX" transports="vfs" startOnLoad="true" trace="disable">
<description/>
<target>
<inSequence>
<class name="com.test.read"/>
<log level="custom">
<property name="status" value="file read"/>
</log>
</inSequence>
</target>
<parameter name="transport.PollInterval">1</parameter>
<parameter name="transport.vfs.FileURI">file:///source</parameter>
<parameter name="transport.vfs.MoveAfterProcess">file:///target</parameter>
<parameter name="transport.vfs.FileNamePattern">.*.txt</parameter>
<parameter name="transport.vfs.ContentType">text/plain</parameter>
After the file is processed, the file will be moved to folder target. So how can I keep the file without moving or delete it?
Thanks :)
Just change the transport.vfs.MoveAfterProcess to original location, which will keep the file there even after being processed.
<proxy name="XXX" transports="vfs" startOnLoad="true" trace="disable">

WSO2 ESB Web destroys nice synapse XML structure

We developed our proxies, sequences and so on with a XML editor and had a very good structure of the synapse configurations, but as we open the component with the web interface and the whole code is realigned and changed.
Is there a way to see the content of the components with the web without destroying the whole structure?
This here was our code:
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="patient_toMPI_pJMS_qToMPIXml" statistics="disable" trace="disable" transports="jms">
<parameter name="transport.jms.Destination">queueName</parameter>
<parameter name="transport.jms.ConnectionFactory">queueBlocking</parameter>
<parameter name="transport.jms.DestinationType">queue</parameter>
<parameter name="transport.jms.ContentType">
<rules>
<jmsProperty>contentType</jmsProperty>
<default>application/xml</default>
</rules>
</parameter>
<target faultSequence="rollbackSequence">
<inSequence>
<property name="frameworkContext" expression="get-property('default', 'frameworkContext')" scope="transport"/>
<property name="frameworkMessageId" expression="get-property('default', 'frameworkMessageId')" scope="transport"/>
<property name="frameworkTransactionId" expression="get-property('default', 'frameworkTransactionId')" scope="transport"/>
</inSequence>
</target>
After opening just once with the web interface it looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="patient_toMPI_pJMS_qToMPIXml"
transports="jms"
startOnLoad="true"

<inSequence>
<property xmlns:urn="urn:hl7-org:v2xml"

<property xmlns:urn="urn:hl7-org:v2xml"

name="frameworkMessageId"
expression="get-property('default', 'frameworkMessageId')"
scope="transport"/>
<property xmlns:urn="urn:hl7-org:v2xml"
xmlns:hl7="http://wso2.org/hl7"
name="frameworkTransactionId"
expression="get-property('default', 'frameworkTransactionId')"
scope="transport"/>
</inSequence>
</target>
<parameter name="transport.jms.ContentType">
<rules>
<jmsProperty>contentType</jmsProperty>
<default>application/xml</default>
</rules>
</parameter>
<parameter name="transport.jms.ConnectionFactory">queueBlocking</parameter>
<parameter name="transport.jms.DestinationType">queue</parameter>
<parameter name="transport.jms.Destination">queueName</parameter>
</proxy>
Is this a bug within WSO2? Is it configurable?
I don't see much change done in your configuration. Properties are pushed down to the bottom (thats the only change I see) and thats the normal behaviour in WSO2 ESB.
There is no way to view the source without using the web console (unless you view it from the file system).
