Restrict the Mule from picking file in SFTP - mule

How to restrict picking the empty file ie 0 kb text file through SFTP in Mule?

you can extend the sftp connector functionality using the "sevice over rides" concept.
you can check the size of the file content before control comes to flow.

Please look sizeCheckWaitTime,fileAge attributes.
I was facing use 0 byte issue. I resolved using above attributes.

Sub VI connector for different cluster types

I want to program an API to generate JSON files.
The standard Labview VI "Flatten to Json" has the connector "anything" which I also want to use.
How is that possible?
https://www.ni.com/docs/de-DE/bundle/labview-2020/page/glang/flatten_to_json.html
Use the existing JSONText library found in LV2019 and later. The subVIs therein are malleable VIs that do exactly what you're requesting. If for some reason you don't like how they work, they're open source and editable.

How do i copy webdynpro application into a text file

I am copying my abap/ooabap code into text file.
How do i copy a webdynpro applicaton this way.
I don't want to use transport requests.
I guess this is not possible as with normal programs. If you do not want to use transport requests, the default way is using SAPlink.

Mule Studio: Mule Flow: Use of File

Within my flow - I am trying to read username pwd from a file based on a key sent by the user.
Question:
Does Mule allow to read data from the file (it can contain set of
user keys and every key will have a uname/pwd
What connector to use it?
To read a single file, you can use the Mule Requester Module.
<mulerequester:request resource="file://${my.filename}"/>
to read a file can use file inbound, the payload after file inbound will be the content of the file
There is a lot of documentation that shows users different ways to read a properties file in Mule flows.
Here are three approaches on how you can do this:
Reading a properties file using ${Key} expression
Reading a properties file using ![p[‘Key’]] expression
Reading a properties file using p() function from DataWeave

How can i use the Mule Studio data mapper for producing output generated from a complex XSD schema ?

I want to post a message to a SOAP webservice with MULE Enterprise edition.
For creating the Request object i am using a data mapper with the
input a POJO and for
the output i selected XML , and from example XML schema i added my own XSD.
Because there are a lot of elements in the xsd, i selected the root element from the list provided.
Then i am dragging the fields from input to the corresponding values i want in the output.
(i also tried to map just one field, to be sure that i keep the minimum the probability for error).
And now the problem:
when the flow is accessed, the following WARN is shown and the data-mapper fails
*[XML WRITER:EXT_XML_WRITER0] - Invalid mapping (With port binded to root element, result might contain multiple root elements. Such XML is not well-formed. To avoid that, set 'Records per file' or 'Max number of records' component attribute to '1'.)*
Where can i set this kind of options in the data mapper ?
And also i want the root element to be only one, i don't need a foreach for the root element, i just need to fill the contents of it. Can i specify this anywhere in the data mapper ?
Thanks.
Mule EE DataMapper uses CloverETL for data transformations, and this annoying warning concerns CloverETL settings. I don't know if you can advise CloverETL to use a specific configuration file in the context of Mule DataMapper, but you can always edit the mapping file generated by Mule with a text editor. Just find your root Node entry in the mapping file and add recordsPerFile="1" attribute.
The problem with this is that Mule may overwrite your manual edits if you use the graphical editor, though.
Check out the Anypoint Studio May 2014. Mule now includes a new Web Service Connector for posting messages to a SOAP web service using just a WSDL. Studio will read the XML Schema from the WSDL and automatically create the metadata for DataMapper for you. See http://www.mulesoft.org/documentation/display/current/Web+Service+Consumer for more details.

How is file upload handled in HTTP?

I am curious to know how webservers handle file uploads.
Is the entire file sent as a single chunk? Or is it streamed into the webserver - which puts it together and saves it in a temp folder for PHP etc. to use?
It's just a matter of following the encoding rules so that one can easily decode (parse) it. Read on the specification about multipart-form/data encoding (the one which is required in HTML based file uploads using input type="file").
Generally the parsing is done by the server side application itself. The webserver only takes care about streaming the bytes from the one to the other side.
It's streamed to answer that question, but see this RFC 1867 for more information.
RFC 1867 describes the mechanism.
