I had started writing a simple Munit test for one of my flow. In the main flow. I have added a Munit set event to set some URI params to the mainflow.
<munit:test name="business-logic-test-suite-mainFlowTest" description="Test">
<munit:set-event cloneOriginalEvent="false">
</munit:set-event>
<set-payload value="#[payload]" doc:name="Set Payload"/>
<flow-ref name="mainFlow" doc:name="Flow-ref to mainFlow"/>
<munit:assert-payload-equals message="Output message is not matching excepted value #[payload]" expectedValue="#[payload]" doc:name="Assert Payload"/>
</munit:test>
When I try to run the test, the studio is throwing an error "Invalid content was found starting with element 'munit:set-event'". I tried some search on the internet and could not find anything related.
Any clue what could be missing ?
Thanks
If you want to set URI params, you can use Set Message component.
Another way to set the URI params is Message Properties component.
You can use this link for your reference.

I am using a Message Enricher to call a web services and return what a part number is for the external data source. I am saving that payload into a Session Variable. I am then using a Lookup Table from within a Datamapper to send the current payloads' part number to be referenced against the external data source (using xpath). I am able to invoke the Lookup and pass the local variable but the payload that was saved into the Session Variable is not being passed through to the Lookup Flow, so my xpath query will not work.
Here is the Session Variable and Datamapper
<flow>
<enricher target="#[sessionVars['SesVar']]" doc:name="Message Enricher">
<flow-ref name="query-line-details-erpFlow" doc:name="query-line-details-erpFlow"/>
</enricher>
<logger message="Session Var: #[sessionVars['SesVar']]" level="INFO" doc:name="Logger"/>
<data-mapper:transform config-ref="XML_To_XML" doc:name="XML To XML"/>
</flow>
Here is the Lookup Table logic
output.ExternalPart = (isnull(lookup(LookUpPart).get([input.LocalPart])) ? null : lookup(LookUpPart).get([input.LocalPart]).ExternalPart);
Finally here is the second flow where the Session Var should be accessed from
<flow>
<logger message="Spit out the var #[sessionVars.SesVar]" level="INFO" doc:name="Logger"/>
</flow>
From what research I have done, the Session Variable is not passing a Transport Barrier so it should be able to be referenced from this scope. I have also tried with flowVars also.
Any help would be greatly appreciated.
I'm not sure, how can we extract the flow-name and message-processor Name through MEL. For example I have multiple message processor. For logging, i need to extract the flow Name and Message-processor, so that I can find out transaction has crossed this particular flow and its message processor. Is there any simple way to find out. Please guide me. Please find the screenshot below. Here i need to Extract - set payload and its flowName (flow1)
Thanks in advance.
For mule 3.8+ version onwards #[flow.name] don't work.
Use #[mule:context.serviceName] expression in logger or component to extract the name of the flow
I know this post is old but I have been trying to find a way to do this in MEL for error handling emails.
For the flow name you can use #[exception.event.flowConstruct.name]
for the failing message processor you can use #[exception.failingMessageProcessor].
Both of these work in MEL without the need to use an flowVar.
Please note however, that the failing processor does not always come back with a value but comes back with null, I'm not sure why.
You can extract the flow-name with MEL : #[flow.name]
<flow name="name" doc:name="name">
<http:inbound-endpoint address="http://localhost:8090/resources" doc:name="HTTP" />
<logger message="name of flow: #[flow.name]" level="INFO" doc:name="Logger"/>
<set-payload value="name" doc:name="Set Payload"/>
</flow>
or
flowConstruct.getName() in a Message Processor
Two ways to acthive this (from current flow name)
First one is -
<logger message="Current flowName: #[flow.name]" level="INFO" doc:name="Logger"/>
and the second one is -
<logger message="Current flowName: #[context:serviceName]" level="INFO" doc:name="Logger"/>
I have a flow where I want to evealuate an expression on the smtp subject attribute but always get mvel parse expression though the logger give me the right values.
<json:object-to-json-transformer doc:name="Object to JSON"/>
<logger message="MYRequestPayloadID #[json:RequestPayloadID] #[json:ResponseStatusCd]" level="DEBUG" doc:name="Logger"/>
<smtp:outbound-endpoint host="${mail.host}" to="${mail.to}" from="${mail.from}" subject="Error Response for PayloadID #[json:RequestPayloadID], Status #[json:ResponseStatusCd]" responseTimeout="10000" doc:name="SMTP />
I am not sure why in the subject #[json:RequestPayloadID] and #[json:ResponseStatusCd] evaluation fail though I get the data back in the logger . Thanks.
Expressions are not supported everywhere in Mule (alas): this is one place where it isn't.
You have to use message properties to set the subject dynamically:
<set-property propertyName="subject"
value="Error Response for PayloadID #[json:RequestPayloadID], Status #[json:ResponseStatusCd]" />
FTR json: is the old expression style, nowadays you should be using MEL instead: http://www.mulesoft.org/documentation/display/current/Mule+Expression+Language+Tips#MuleExpressionLanguageTips-JSONProcessing
I am just starting to learn mule so please forgive me if this is a very basic question.
I have successfully configured mule to monitor my mail box so whenever a mail comes in I write the mail to text file (just for testing).
Now I need to parse this mail and get the message / From / To from the mail.
<flow name="testFlow" doc:name="testFlow">
<imap:inbound-endpoint host="ip"
port="143" user="username" password="pwd" doc:name="IMAP"
responseTimeout="10000" transformer-refs="Message_Properties">
</imap:inbound-endpoint>
<file:outbound-endpoint path="C:\"
outputPattern="#[function:datestamp].dat" doc:name="File">
</file:outbound-endpoint>
</flow>
I thought I would be able to get the header information using the below expression (using expression transformer)
#[inboundProperties['email-header-name']]
but this doesn't seem to work. I also tried the below expressions but didn't work,
#[map-payload:HOST]
#[map-payload:MESSAGE]
#[map-payload:TIMESTAMP]
Can someone help? Also does anyone know if there is a document with the list of available expressions?
EDIT:
I included the logger to view the properties and it displayed all the properties but I couldnt find the body.. Also, I tried getting the fromAddress using
#[map-payload:fromAddress] and #[inboundProperties['fromAddress']]
but didn't work, can someone let me know where I am wrong?
The properties are something like below,
inbound.fromAddress=Service <service#xx.com>
inbound.subject=Test Final inbound.toAddresses=Service
Edit 2:
This is what I have tried but doesnt work :(
I am trying to retrieve the email subject and write to file or just show it using logger based on email subject but I am getting the below error.

Unfortunately the IMAP connector documentation doesn't list the message properties created when a new message is received. You can find all the created properties by adding:
<logger level="WARN" />
after the imap:inbound-endpoint. This will log all the message meta information, including properties, at WARN level.
You can also find the property names in the MailProperties JavaDoc. For example inbound.fromAddress is the inbound property that contains the sender's email address.
The message body is the text email content, unless it's a multi-part email. In that case, if the first part is text/plain, it will be set as the message payload, otherwise all parts will be available as inbound message attachments.
<flow>
<jms:inbound-endpoint queue="InputQueue"/>
<component class="MyComponent"/>
<choice>
<when expression="/Response/Status/Success" evaluator="xpath">
<jms:outbound-endpoint queue="LogInputQueue"/>
<jms:outbound-endpoint queue="SuccessQueue"/>
</when>
<when expression="/Response/Status/Error" evaluator="xpath">
<jms:outbound-endpoint queue="LogInputQueue"/>
<jms:outbound-endpoint queue="ErrorQueue"/>
</when>
<otherwise>
<jms:outbound-endpoint queue="LogInputQueue"/>
<jms:outbound-endpoint queue="ExceptionQueue"/>
</otherwise>
</choice>
</flow>
In this flow, MyComponent returns either success message as a response or error response or exception?
I need to log the original message from InputQueue in LogInputQueue in all the cases. How do I achieve this in my flow?
Did you mean to create a log file? In that case, you have to implement log4j using slf4j and use the line
<logger level="log_level" category="your_category" message="#[message:payload]"/>
where log_level is your desired logging level- "error", "debug", "info" etc...
your_category is your category of log defined in the log4j.properties file (it is optional actually)
and message="#[expression:value]" is your message to be logged given as an expression:scope:key combination. Scope is optional here.
Using log4j or slf4j you can log the payload.
[payload],we have logger component using this log payload in console.
Since, you need to send original message from InputQueue to LogInputQueue in all the cases, as you mentioned, what you need to do is :-
1. Remove <jms:outbound-endpoint queue="LogInputQueue"/> from all the cases in choice block
2. Store the original payload from InputQueue in a variable by placing it just after the JMS inbound endpoint
3. At the end of the flow, after the choice router, set the payload in set payload component from variable you stored the original payload
4. Now put <jms:outbound-endpoint queue="LogInputQueue"/> after your set payload component.
In this way you will able to send the original payload to the LogInputQueue as per your requirement.
