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

Team,
I have service to register a user with certain data along with unique mail id and phone no in JSON file format as a body (for ex: registerbody.json).
Before Post call I am generating unique mail id , phone no and updating the same json file (registerbody.json) fields which is in the same folder where feature file locates. I see the file is updated with the required data during runtime.
I used read () method and performed POST request
Surprisingly read method is not taking updated JSON file instead it is reading old data in the registerbody.json file.
Do you have any idea on this, why it is picking up old data even though file is updated with the latest information?
Please assist me with this.
Karate uses the Java classpath, which is typically target/test-classes. So if you edit a file in src/test/java Karate won't see it unless it is copied. This copying is automatically done when you build / compile your code.
My suggestion is use target/ as a temp folder and then you can read using the file: prefix:
* def payload = read('file:some.json')
Before Post call I am generating unique mail id , phone no and updating the same json file (registerbody.json)
You are making a big mistake here, Karate specializes in updating JSON based on variables. I suggest you take 5 minutes and read this part of the docs VERY carefully: https://github.com/intuit/karate#reading-files
Especially the part about embedded expressions: https://github.com/intuit/karate#embedded-expressions
I am using Mule 4 and Anypoint 7.
In my flow I want to insert records into a database but still keep the original payload in the message.
Previously I would have placed the database connector into an enricher scope so that the original payload is not replaced after the database action has completed.
How can I do this using Mule 4?
I do have the alternative of saving the payload as a variable and then use set payload after the database action but there are a few different database actions and thought the enricher scope made the flow look cleaner so just wanted to see if the functionality was still there somewhere.
Thanks
As you've seen, Enrichers are no longer a scope in Mule 4. We need to use Targets now to achieve similar functionality. Go to the 'Advanced' tab of the Insert configuration and in the Output section specify the 'Target Variable' and 'Target Value'. This provides the same functionality as an enricher.
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.
I have a mule application comprising of 10 mule XML files. Some of these XML files need to use same property from commong prperties (config.properties) file.
(1) Should ALL the flows that need use a given property load the properties file containing that property using --
<context:property-placeholder location="config.properties" />
(2) OR should only one of the XML file add property-placeholder?
(3) If option (2) is right, then does the order of mentioning the xml files as config.resources in mule-deploy.properties play any role?
Please shed some light on this.
You only need it once, and it does not matter where you put it.
You only need one property file and you can setup this for 3 environments liks DEV,QA and PROD and setop property to pick right file.

If you deploy multiple applications through a Shared Resources structure, don’t set anything in the properties files, as there might potentially be conflicts between the various apps that share a domain. Instead, set environment variables over the scope of the deployed app, its domain, and other apps under that domain.
As explained in Shared Resources, in Studio you can create these variables through the Environment tab of the Run Configurations menu, reachable via the drop-down menu next to the Play button.
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.
