Please note below points
the above flow will create files (pdf,ppt,image ) with corrupted format in C:\OUTPUT folder
the file i want to move like pdf,ppt,image etc.
anyone suggest solution for that
If your requirement is to just move the files with some particular extenstions, this can be done by using File inbound and file outbound endpoints. Your flow should look like as follows
<flow name="testFlow1" doc:name="testFlow1">
<file:inbound-endpoint path="C:\Input" responseTimeout="10000" doc:name="File">
<file:filename-regex-filter pattern="*.pdf" caseSensitive="true"/>
</file:inbound-endpoint>
<logger message="#[payload]" level="INFO" doc:name="Logger"/>
<file:outbound-endpoint path="C:\Output" responseTimeout="10000" doc:name="File"/>
</flow>

Below is my mule configuration, i want to acknowledge using client acknoledge , how can i do it?
<mule>

<jms:transaction action="NONE"/>
</jms:outbound-endpoint>
</flow>
<flow name="JmsInboundFlow">
<jms:inbound-endpoint queue="logfilequeue" connector-ref="Active_MQ" doc:name="JMS">
<jms:client-ack-transaction action="ALWAYS_BEGIN"/>
</jms:inbound-endpoint>
<logger message="#[payload.toString()]" level="INFO" doc:name="Logger"/>
<file:outbound-endpoint path="D:\mule\output" responseTimeout="10000" doc:name="File" outputPattern="#[message.inboundProperties.fileName]"/>
</flow>
</mule>
Note: Be REALLY sure you want to use CLIENT_ACKNOWLEDGE it doesn't work like most people think. It ack's the current message AND all previous within the session. If you have parallel/threaded consumers this setting will inadvertently ack messages that aren't ready to be ack'd yet. ActiveMQ has a INDIVIDUAL_ACKNOWLEDGE which ack's just the single message.
JMS Spec 2.0 has feat requests to make this add'l ack mode a standard.
Try adding acknowledgementMode="CLIENT_ACKNOWLEDGE" in your JMS connector.
You can refer this question for more details
Mule jms with CLIENT_ACKNOWLEDGE mode? Message automatically consumed even though I didn't acknoeledge it
<flow name="testFlow1" doc:name="testFlow1">

<!--line 6 --> <!-- <set-payload value="==no downlaod=#[payload]" doc:name="Set Payload"/>-->
</flow>
when I run the application with url: host:port/dbtest, I am getting file downloaded. How can I avoid downloading file? If i enable line 6, I don't get file downloaded, instead it displays in browser.
Since you have used HTTP inbound 'exchange-pattern' as request-response. When you enable setpayload(line 6) it is returning to brower. If you dont want that, make HTTP exchange-pattern as one- way.
I tried the flow by adding an 'Object-to-String' transformer. It is working for me. The file is not downloading. Here is the flow.
<flow name="sampleflow">
<http:listener config-ref="HTTP_Listener_Configuration" path="/"doc:name="HTTP></http:listener>
<db:select config-ref="MySQL_Configuration" doc:name="Database">
<db:parameterized-query><![CDATA[select id,name,designation,address from myrest]]></db:parameterized-query>

I want to run one thread at a time in my mule flow. And also i want to take input only one by one, i.e.,for first input once I completed with the flow, only then Mule flow picks the second input. Which strategy should I use??
If I used synchronous strategy, and we have two or more than two files in a folder looking by Mule Flow, it picks all the input at a time.
And if i use asynchronous strategy and 1 thread at a time, then I am not able to complete the full flow before taking any other input.
<flow name="Catalog_command_Execution" doc:name="Catalog_command_Execution" processingStrategy="synchronous">

</flow>
From the kind of scenario you are looking for processing one file after another Mule Synchronous processing strategy should serve the purpose.
If you see Mule picking up more than one file then the flow needs to be looked at as to why this is happening.
Update:
The processing strategy on your flow for WMQ inbound is not synchronous. Then it should work as expected.
<flow name="CatalogueFlow_AB" doc:name="CatalogueFlow_AB" processingStrategy="synchronous">
Hope this helps.
Old thread but have you tried setting the WMQ consumer count to 1?
Flow can be synchronous but that doesn't mean the inbound connector will work in a synchronous manner. For file based connector you can set dispatcher to be non-threaded and for WMQ you should try to make consumers to 1.
I tried to create a Data-Mapper example in mule in which both inbound and outbound endpoints are File, Looks some thing like.
When i execute this program output folder of file remains empty, Logically i assume that i need to put and HashMap to XML transformer between Data Mapper and Output File. More Over i created a csv file to xml file selecting from example option in data mapper.
Initially i tried to use FTP endpoint it started resulting into error so i replaced FTP with file endpoint.
Here I am Sharing configuration.xml file
<mule xmlns:file="....>
<data-mapper:config name="sample_mapper_grf" transformationGraphPath="sample_mapper.grf" doc:name="DataMapper"/>
<flow name="CSV_to_XML_Data_MapperFlow1" doc:name="CSV_to_XML_Data_MapperFlow1">
<file:inbound-endpoint path="/home/jay/CSV_XML_/input" responseTimeout="10000" doc:name="Input File"/>
<data-mapper:transform config-ref="sample_mapper_grf" doc:name="DataMapper"/>
<file:outbound-endpoint path="/home/jay/CSV_XML_/output/" responseTimeout="10000" doc:name="Output File"/>
</flow>
</mule>
Data-Mapper configuration image is here
Add a Groovy component after the data mapper and try and dump the contents
println "post mapping payload " + payload
return payload
I got it resolved using.
here is the configuration.xml
<mule ....>
<data-mapper:config name="sample_mapper_grf"transformationGraphPath="sample_mapper.grf" doc:name="DataMapper"/>
<flow name="CSV_to_XML_Data_MapperFlow1" doc:name="CSV_to_XML_Data_MapperFlow1">
<file:inbound-endpoint path="/home/jay/CSV_XML_/input" responseTimeout="10000" doc:name="Input File"/>
<data-mapper:transform config-ref="sample_mapper_grf" doc:name="DataMapper"/>
<object-to-string-transformer doc:name="Object to String"/>
<file:outbound-endpoint path="/home/jay/Output" responseTimeout="10000" doc:name="File" outputPattern="#[function:dateStamp].xml"/>
</flow>

I have a mule flow as under
<flow name="flow1" doc:name="f1">
<file:inbound-endpoint path="C:\input" responseTimeout="10000"
doc:name="File" />
</flow>
<flow name="flow2" doc:name="f2">
<http:inbound-endpoint address="http://localhost:8080"
doc:name="HTTP" exchange-pattern="request-response" />
<flow-ref name="flow1" doc:name="Flow Reference" />
<file:outbound-endpoint path="C:\outputfile"
responseTimeout="10000" doc:name="File" />
</flow>
I am trying to move/upload multiple files from source to destination (can be anything e.g. FTP or File outbound etc..) by using the flow.
The reason for doing in this way is that I want to invoke the job from CLI(Command Line Interface) using CURL.
But it is not working....
Edited
I need to pick up some files(multiple files) from a particular folder located in my hard drive. And then move those to some outbound process which can be FTP site or some other hard drive location.
But this flow needs to be invoked from CLI.
Edited (Based on David's answer)
I now have the flow as under
<flow name="filePickupFlow" doc:name="flow1" initialState="stopped">
<file:inbound-endpoint path="C:\Input" responseTimeout="10000" doc:name="File"/>
<logger message="#[message.payloadAs(java.lang.String)]" level="ERROR" />
</flow>
<flow name="flow2" doc:name="flow2">
<http:inbound-endpoint address="http://localhost:8080/file-pickup/start" doc:name="HTTP" exchange-pattern="request-response"/>
<expression-component>
app.registry.filePickupFlow.start();
</expression-component>
<file:outbound-endpoint path="C:\outputfile" responseTimeout="10000" doc:name="File"/>
</flow>
I am getting couple of problems
a) I am getting an error that - Attribute initialState is not defined as a valid property of flow
However, if I remove that attribute, the flow continues without waiting for "http://localhost:8080/file-pickup/start" to fire up.
b) The files are not moved to the destination folder
So how can I do so?
You can't reference a flow that has an inbound endpoint in it because such a flow is already active and consuming events from its inbound endpoint so you can't invoke it on demand.
The following, tested on Mule 3.3.1, shows how to start a "file pickup flow" on demand from an HTTP request.
<flow name="filePickupFlow" initialState="stopped">
<file:inbound-endpoint path="///tmp/mule/input" />
<!-- Do something with the file: here we just log its content -->
<logger message="#[message.payloadAs(java.lang.String)]" level="ERROR" />
</flow>
<flow name="filePickupStarterFlow">
<http:inbound-endpoint address="http://localhost:8080/file-pickup/start"
exchange-pattern="request-response" />
<expression-component>
app.registry.filePickupFlow.start();
</expression-component>
<set-payload value="File Pickup successfully started" />
</flow>
HTTP GETting http://localhost:8080/file-pickup/start would then start the filePickupFlow, which in turn will process the files in /tmp/mule/input.
Note that it is up to you to configure the file:connector for what behavior it must have for files it processes, either deleting them or moving them to another directory are two main options.
I guess in this case a File inbound to read a file on demand will not be helpful.
Please try if the follwoing way.
<flow name="flow1" doc:name="f2">
<http:inbound-endpoint address="http://localhost:8080"
doc:name="HTTP" exchange-pattern="request-response" />
<component>
<spring-object bean="fileLoader"></spring-object>
</component>
<file:outbound-endpoint path="C:\outputfile"
responseTimeout="10000" doc:name="File" />
</flow>
So the Custom component will be a Class which reads the file from your specified location.
Hope this helps.
You can use Mule Requester for a clean solution. See the details in the blog entry Introducing the Mule Requester.
