This is my main mule flow:
HTTP > Payload > File (Create) > Property (File Name) JMS
And that JMS calls to other flow that starts with JMS
JMS > JSON TO XML > File (Delete by file name)
Firstly, I create a file with the JSON message.
And finally, when JSON message is transformed to XML, I try to delete the file by name calling a property that tell me the name.
But the files doesn't delete. Its output this action by log:
Writing file to: C:\errors\91fa03a0-dd33-11e5-a0d9-408d5c4c1bf3.dat
How can I do to delete it?
I tried with the option autoDelete in the Connector Configuration but it doesn't delete.
<file:connector name="File1" outputPattern="#[message.inboundProperties.fileName]" autoDelete="true" streaming="false" validateConnections="true" doc:name="File"/>
You can't use this file outbound endpoint to delete a file.
If you would use something like S3 for example you can, but those connectors are 'operation-based'.
It's meant to write an new file or append data to an existing one.
The autoDelete option is for deleting the file once it has been read by a file inbound endpoint.
More info:
https://docs.mulesoft.com/mule-user-guide/v/3.7/file-transport-reference
If you want to delete and for your usecase you should use a piece of JAVA code and use methods from the File Class:

I have a logic app in Azure. The trigger is to check when an email arrives into a specific folder in a mailbox. An email may contain 1 or more attachments.
Once triggered, I have an HTTP request that gets sent to a SOAP service. The idea is that I want to check if the filename exists at the SOAP Service.
Its all working perfectly, with the exception, when I reference the filename from the trigger, it includes the file extension. I need to somehow ignore the ".PDF" part of the filename
Below is the XML I post to the SOAP service. Lets say the filename is 12345.pdf, then I need /UniversalEvent/Event/ContextCollection/Context/Value to = "12345" and not "12345.pdf":
<UniversalEvent xmlns="http://www.cargowise.com/Schemas/Universal/2011/11" version="1.1">
<Event>
<DataContext>
<DataTargetCollection>
<DataTarget>
<Type>ForwardingShipment</Type>
</DataTarget>
</DataTargetCollection>
</DataContext>
<EventTime>#{utcNow()}</EventTime>
<EventType>Z77</EventType>
<EventReference>Requesting Shipment ID</EventReference>
<IsEstimate>false</IsEstimate>
<ContextCollection>
<Context>
<Type>HAWBNumber</Type>
<Value>#{items('For_each')?['name']}</Value>
</Context>
</ContextCollection>
</Event>
</UniversalEvent>
do you have any suggestions on what function to use to achieve this?
You can change the expression #{items('For_each')?['name']} in your xml to:
#{substring(items('For_each')?['name'], 0, indexOf(items('For_each')?['name'], '.'))}
I have a scenario wherein I need to read files from a particular folder. So I had a File inbound as below, its reading all non-empty files. But empty files are not read and sits in the same location as is.
<file:inbound-endpoint path="${file.path}" responseTimeout="10000" doc:name="File" moveToDirectory="${audit.location}">
<file:filename-regex-filter pattern="file.employee(.*).xml,file.client(.*).xml"
caseSensitive="true"/>
</file:inbound-endpoint>
I removed File filter, but still it doesn't read empty files.
Is there a way to enable file inbound to read empty files too?
According the the Mule File Connector documentation:
The File connector as inbound endpoint does not process empty (0 bytes) files.
So this behavior is expected. There is no documented way to process non empty file with the File Inbound Endpoint.
However you can still write your own connector to do this, or use a workaround such as fill your "empty" file with a single character (such as a space) to make it non-empty
If you want to read a file with the size of 0 KB, then you can`t achieve this with File Connector, but we can read a file by using MuleRequester in the flow. I will share sample snippet soon. Please let me know,If you need any help.

Mule File connector does not process empty (0 bytes) files as inbound endpoint
As per my knowledge File Inbound connector will not process (0 KB) size files.
On the File Connector, the class org.mule.transport.file.FileMessageReceiver.java in method poll has :
if (file.length() == 0)
{
if (logger.isDebugEnabled())
{
logger.debug("Found empty file '" + file.getName() + "'. Skipping file.");
}
continue;
}
that prevents it from proccessing empty files
But you can create your own CustomFileMessageReceiver.java, create your package:
package com.mycompany.mule.transport.file;
And the class that extends AbstractPollingMessageReceiver
public class CustomFileMessageReceiver extends AbstractPollingMessageReceiver
Copy the original FileMessageReceiver.java methods but comment the above lines and change FileMessageReceiver to CustomFileMessageReceiver where needed.
The call fileConnector.move(file, workFile) is a protected method from the original package, commented and beware you cannot use workdir.
In the same package create a copy of org.mule.transport.file.ReceiverFileInputStream.java
Configure your connector:
<file:connector name="FILE" readFromDirectory="${incoming.directory}" autoDelete="true" streaming="false" recursive="true" validateConnections="true" doc:name="File" writeToDirectory="${processed.directory}">
<service-overrides messageReceiver="com.mycompany.mule.transport.file.CustomFileMessageReceiver" />
</file:connector>
Or you may implement your own file connector, as stated in the above answers.
I use a file component in my mule flow that add the payload in that file.
The mule flow is:
HTTP Listener => Payload => File => ...
The component in XML:
<file:outbound-endpoint path="${test}" outputPattern="tested_#[function:datestamp:yyyyMMdd].log" connector-ref="File" responseTimeout="1000" doc:name="File"/>
When I generate the file, it create a folder called test in mule-esb-directory\bin but I want to create it in the project directory for example:
mule-esb-directory\app\MyMuleProject.
I use a properties file to set the path but it does not work.
Now: mule-esb-directory\bin\test
I want: mule-esb-directory\app\MymuleProject
Try using this
src/main/resources/
Or try with absolute path, like this
/opt/mule-esb-directory/app/MymuleProject
I have a Mule application that is writing a file in an outbound endpoint, with the config below:
<file:outbound-endpoint path="${Outbound}" outputPattern="outputFile_#[function:datestamp:yyyyMMddHHmmss].csv" doc:name="Output File"/>
Following this point in the flow I need to display a log message along the lines of "Successfully created file {filename}".
The issue I'm having is that I can't find a way of displaying the name of the file I have just created. I could put: Successfully created file outputFile_#[function:datestamp:yyyyMMddHHmmss].csv, but there is a chance that the datestamp may differ by one second.
Is there a way in Mule that I can display the name of the file I've just written?
UPDATE
Following the response from #til_b, I've achieved this using the following:
<set-variable value="outputFile_#[function:datestamp:yyyyMMddHHmmss].csv" variableName="Filename" doc:name="Variable"/>
<file:outbound-endpoint path="${Outbound}" outputPattern="#[variable:Filename]" doc:name="Output File"/>
<logger level="INFO" message="Successfully created file #[variable:Filename]" doc:name="Logger" />
I dont know about mule, but when i encounter such a problem while programming i store the generated filename in a variable, and then use that variable to actually create the file and display the message.
In Pseudocode:
var filename = #yyyymmddhhMMss.csv
create_file(filename)
log_message(filename + ' successfully created')
I'm testing webservice request with soapUi and need to send parameters to request, stored in config file.
Parameters are:
Key - static parameter, for access to webservice
Parameters 1-4 - dynamic, can change in config file and send to web-service again.
All parameters both Key and Parameters 1-3 I need send to soapui request as config file using groovy script.
Request to web-service like:
<Header/>
<Body>
<request>
<accesskeytoservice>
<key>Key</key>
</accesskeytoservice>
<UseService>
<parameter1>Parameter1<parameter1>
<parameter2>Parameter2<parameter2>
<parameter3>Parameter3<parameter3>
</UseService>
</request>
</Body>
I had tried to store data in csv, txt and xml format and then read it to soapui request parsing data from file, but all tries still didn't work properly.
What format of config file is preferred in this case?
How are you opening and reading your config file? Using Groovy? If you have successfully done that part the rest is simpler. Define two variables and use
context.setProperty(name,value)
Loop until eof.
