There is nothing to solve here: the result of an All Routing Message Processor is a java.util.List of payloads received from each call to each message processor inside the All one.
You must have an object-to-xml transformation configured somewhere: this is why the List payload is turned into XML by using an XStream-powered serialization.
You need to deal with this list, for example with a custom component that can process a java.util.List payload.

Get files from S3 bucket sub folders and process the files in Mule

I have the following folder structure in a S3 bucket called "test-files":
pending-files/products
pending-files/prices
Each folder contains a number of small CSV files and I want to retrieve them all in one call and then process each file in a For Each loop which contains a Choice component to redirect the payload based on the folder name e.g. "products" or "price".
I use List Objects to retrieve the files and have been able to retrieve all the files but the list contains an entry for the folder and the For Each will fail validation due to the folder not being a valid CSV file and also will fail the empty file check because the size will be 0.
How can I do this?

insert into database with anypoint studio

I would like to save the flow coming from this json file: https://gist.githubusercontent.com/Rajeun/3dbbe8ca240d479dbabe/raw/aba5d0ec9345b886426ab767376b7c9cb60c251f/person.json in a database using anypoint studio.
For this i'm using a http connector where i mentioned the link of the json file. and then i used a json-to-object transformer and a database connector.
In my db i have a table with id, token, tel "int" and email is a varchar
-(I tested the connection and its working well).
when i run my code:
ERROR 2015-03-20 13:14:05,522 [main] org.mule.module.launcher.application.DefaultMuleApplication: null

Remove the empty template query:

</db:template-query>
Also, does 'myclass' exist? if not try just using a map:
<json:json-to-object-transformer returnClass="java.util.HashMap" doc:name="JSON to Object"/>
Also It looks like you want to retrieve that JSON file from the specified URL. For that you want the http:request not http:listener. http:listener is used as a message source waiting for requests to your app.
You should use the http:request to request the file and trigger it using a polling message source:
<http:request-config name="HTTP_Request_Configuration" host="www.gist.githubusercontent.com" port="80" doc:name="HTTP Request Configuration"/>
<flow name="testFlow">
<poll>
<http:request config-ref="HTTP_Request_Configuration" path="Rajeun/3dbbe8ca240d479dbabe/raw/aba5d0ec9345b886426ab767376b7c9cb60c251f/person.json" method="GET" doc:name="HTTP"/>
</poll>

Mule ESB, returning the Database Connector data in a JSON like format

I have a simple flow, that receives a REST, but without any corresponding data being input to the flow
The following is the XML:
<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns:db="http://www.mulesoft.org/schema/mule/db" xmlns:tracking="http://www.mulesoft.org/schema/mule/ee/tracking" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

<flow name="test2Flow1" doc:name="test2Flow1">

<db:select config-ref="Generic_Database_Configuration" doc:name="Database" doc:description="test">
<db:parameterized-query><![CDATA[SELECT ACCTNUM FROM xxx.ACCOUNT]]></db:parameterized-query>
</db:select>
</flow>
</mule>
The SQL from the command line (outside of Mule) returns the following:
db2 => SELECT ACCTNUM FROM xxx.ACCOUNT
ACCTNUM
----------
11111
22222
The flow then executes a fully configured Database Connector, The data ten is passed to the outbound http connector:
C:\curl>curl http://localhost:8081
¼φ ♣sr ¶java.util.LinkedList♀)S]J`ê"♥ xpw♦ ☻sr $org.mule.util.CaseInsensitive
HashMap¥╤┘∩gE╬ ♥ xpw♀?# ► ☺t ACCTNUMt
11111 xsq ~ ☻w♀?# ► ☺q ~ ♦t
22222 xx
...so you can see that it is getting the variables from the table '11111' and '22222'.
What I don't know yet is what to do now. I want to take the result of the Database Connector, and return the strings '11111' and '22222'. in a JSON like format, but I do not know how to do that
Could someone please tell me the exasiest way to do that, and perhaps provide an example?
Thanks

Yes you are going right .... Just put a Object to JSON Transformer after the DB connector at the end like <json:object-to-json-transformer doc:name="Object to JSON"/> ... see the following :-

How to returned with custmise response to client using Mule ESB

I am new for the mule esb but i know other ESB patterns
my issue is i have done a sample which will insert a data into DB.its working fine but its not giving any response to client so client is getting nothing from server
my sample code is
<mule xmlns:json="http://www.mulesoft.org/schema/mule/json"
xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:jdbc-ee="http://www.mulesoft.org/schema/mule/ee/jdbc"

<jdbc-ee:query key="INSERT_TOKEN" value="insert into users(FirstName,lastname) values(#[message.payload.name],#[message.payload.id]);"/>
</jdbc-ee:outbound-endpoint>
</flow>
</mule>
and i am calling to this using sample JSON client like this
curl -H "Content-Type: application/json" -d '{"name":"kk","id":"anil"}' http://localhost:8081/httpPost
when i am running this json its giving nothing response but i wish to give response like this {"ResponseJSON":{"Body":{"Datalist":{"Data":"Successfully Rows inserted"}},"Status":"200"}}
how would i format this above format i used http response builder but there is nothing to do like this..

you need to add an Echo component, set the payload to the value you are looking for and add a HTTP Response Builder with status="200" and contentType="application/json".
Add the following lines after </jdbc-ee:outbound-endpoint> and before </flow>
<response>
<http:response-builder status="200" contentType="application/json" doc:name="HTTP Response Builder"/>
</response>
<response>
<set-payload value="{"Body":{"Datalist":{"Data":"Successfully Rows inserted"}},"Status":"200"}}" doc:name="Set Payload"/>
</response>
<echo-component doc:name="Echo"/>
Cheers,
-Marco.

Mule ESB : Cannot copy message with a stream payload

I have a Mule Application where I send a Request to Multiple WebServices and aggregate the List of responses i get , the idea is to get the first response of the List by returning it from the CustomJavaClass where the list is handled :
return responses.get(0);
I am able to reach the WSDL if I try to reach it over a Browser , the returned WSDL looks like its supposed to look . But i I try to send a message via SoapUi i get the following exception :
Exception stack is:
1. Cannot copy message with a stream payload. Payload type is "org.apache.commons.httpclient.ContentLengthInputStream". Message payload is of type: ContentLengthInputStream (org.mule.api.MessagingException)

Getting the WSDL works because the GET request carries no payload. But when you try to invoke a SOAP method, the POST payload is an InputStream, which of course can't be dispatched several times.
Thus: serialize the HTTP input stream with a:
<object-to-byte-array-transformer />
right after the http:inbound-endpoint.
