I am trying to upload an XML file from a HTML page to Mule-3.5 (CE). In Mule, I am unable to retrieve the contents of the file. I am attaching the HTML and the Mule configuration xml. I hope someone could help me through this.
<html>
<body>
<form action="http://localhost:8081" method="post" enctype="text/xml" >
INVOIC IDOC File:<input type="file" name="uploadedFile" size="40" accept=".xml" />

The Mule script is just a test for HTTP connector. I am searching ways to extract the contents of the file uploaded.
You could use this to get things working. The thing that I have changed in the HTML is the enctype and the name of the file input.
<html>
<body>
<form action="http://localhost:8081" method="post" enctype="multipart/form-data" >
INVOIC IDOC File:<input type="file" name="payload" size="40" accept=".xml" />
<input type="submit" name="Submit" id="button" value="Send" />
</form>
</body>
</html>
for the Mule part you can use the HttpMultipartMuleMessageFactory for the HTTP connector. This lets you receive multipart/form data. Since the file input was named payload it will be the payload om the mule message, it will be a streaming payload.
Below is a sample mule flow for receiving the xml in mule and logging the payload. I use a simple object-to-string transformer to read the stream.
<http:connector name="HTTP" doc:name="HTTP">
<service-overrides messageFactory="org.mule.transport.http.HttpMultipartMuleMessageFactory" />
</http:connector>
<flow name="http-xml-receive-flow" doc:name="http-xml-receive-flow">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" doc:name="HTTP"/>
<object-to-string-transformer doc:name="Object to String"/>
<logger message="#[message.payload]" doc:name="Logger" level="INFO"/>
</flow>
If you plan to include other form inputs they will be available as inboundAttachments on the mule message.

I have the following html, which uploads multiple files to the URL http://localhost:5000/intake:
<form method="post" action="http://localhost:5000/intake" enctype="multipart/form-data" >
<input name="filesToUpload[]" id="filesToUpload" type="file" multiple />
<input type="submit" value="Send now" >
</form>
But in Mule, I always receive only one file.
This is my mule config:
<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="5000" doc:name="HTTP Listener Configuration"/>
<file:connector name="File" autoDelete="true" streaming="true" validateConnections="true" doc:name="File"/>
<flow name="simpletestFlow">
<http:listener config-ref="HTTP_Listener_Configuration" path="/intake" doc:name="HTTP" allowedMethods="POST" responseStreamingMode="NEVER"/>
<foreach collection="#[message.inboundAttachments]" doc:name="For Each">
<file:outbound-endpoint path="C:/Users/U595036/AnypointStudio/Production/upload/src/main/wsdl" outputPattern="#[key]" connector-ref="File" responseTimeout="10000" doc:name="File"/>
</foreach>
</flow>
The #[message.inboundAttachments] always has only one file in it, even if the browser sends many.
Mule can handle only one file at a time(A thread per record),In your case you can upload your files to a folder and through ftp you can process the flow.
I am trying to create a flow in Mule 3.7.3 which reads a CSV file from an input folder, does some processing and then writes the original CSV file to an output folder at the end of the flow when everything has completed successfully.
I thought I would save the CSV in a variable and then set the payload using this variable before it creates the file in the output directory.
Everything worked ok when I just had the two sftp connectors to read and write in the flow but then when I added a transform message connector, the file written to the output folder is empty or it fails with a "stream closed" error message. I would have expected the set payload connector to overwrite the transform message so wouldn't have thought there would be a problem.
Does anyone know how I can fix this?
The SFTP server I am using is CrushFTP.

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:

Remove the empty template query:

<db:parameterized-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>

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

</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"/>

So, using Mule ESB, I'm searching Bing for certain PDF files. Then I'm parsing the JSON response to capture the URL of the file location. Now I need to retrieve the file and save locally. Below is what I have so far, but I have a feeling I'm going about this all wrong. How can I complete the use case?
I'm having two problems:
1) Can't figure out how to strip "http" from #[message.payload.Url] (since the HTTP Endpoint adds http to the url I'm passing in.
2) Can't figure out how to retrieve the file. I don't even know if HTTP Endpoint is the right option. HTTP? File?

I couldn't test the flow because some credentials are needed but the following should help you:
Use an expression-transformer to strip the HTTP out,
Your approach with an http:outbound-endpoint followed by a file:outbound-endpoint will work fine,
Change the http:inbound-endpoint to one-way: there is no way to return anything sensible since the execution flow gets split.
For example, assuming message.payload.Url resolves to a java.lang.String, you can use:
<expression-transformer expression="#[org.mule.util.StringUtils.substringAfter(message.payload.Url, 'http://')]" doc:name="Expression"/>
