I have a Mule flow in which I have a Database delete operation :-
<jdbc-ee:connector name="Database_Global" dataSource-ref="DB_Source" validateConnections="true" queryTimeout="-1" pollingFrequency="0" doc:name="Database">
<jdbc-ee:query key="DeleteQuery" value="delete from getData where ID=10"/>
</jdbc-ee:connector>
<flow name="DeleteFlow" doc:name="restFlow1">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" doc:name="HTTP"/>
<jdbc-ee:outbound-endpoint exchange-pattern="request-response" queryKey="DeleteQuery" queryTimeout="-1" connector-ref="Database_Global" doc:name="Database (JDBC)"/>
<logger message="Deleted #[flowVars['MULE_JDBC_UDATE_COUNT']] rows" level="INFO" doc:name="Logger"/>
<set-payload value="Deleted #[flowVars['MULE_JDBC_UDATE_COUNT']] rows" doc:name="Set Payload"/>
</flow>
Now the issue is flowVars['MULE_JDBC_UDATE_COUNT'] is returning null even the row exists and is deleted from Database ... I am using Mule 3.5 anypoint studio with JDBC ee connector ..
One more issue I like to address ... I need something like :-
<choice doc:name="Choice">
<when expression="#[flowVars['MULE_JDBC_UDATE_COUNT']==null] ">
<logger message="Deleted #[flowVars['MULE_JDBC_UDATE_COUNT']] rows... Failed!!!" level="INFO" doc:name="Logger"/>
<set-payload value="Deleted #[flowVars['MULE_JDBC_UDATE_COUNT']] rows ...Failed!!!" doc:name="Set Payload"/>
</when>
<otherwise>
<set-payload value="Deleted Successfully !!!" doc:name="Set Payload"/>
</otherwise>
</choice>
just after the jdbc-ee:outbound-endpoint where I can display success message if row is deleted and failure message if not ... But I am getting error like :-
Root Exception stack trace:
[Error: unresolvable property or identifier: ]]
[Near : {... flowVars['MULE_JDBC_UDATE_COUNT']==null] ....}]
How can I achieve it ... Please help
You have a typo: it's MULE_JDBC_UPDATE_COUNT not MULE_JDBC_UDATE_COUNT.
Finally the working code is MULE_JDBC_UPDATE_COUNT :-
<choice doc:name="Choice">
<when expression="#[flowVars['MULE_JDBC_UPDATE_COUNT']==null] ">
<logger message="Deleted #[flowVars['MULE_JDBC_UDATE_COUNT']] rows... Failed!!!" level="INFO" doc:name="Logger"/>
<set-payload value="Deleted #[flowVars['MULE_JDBC_UDATE_COUNT']] rows ...Failed!!!" doc:name="Set Payload"/>
</when>
<otherwise>
<set-payload value="Deleted Successfully !!!" doc:name="Set Payload"/>
</otherwise>
</choice>

I have defined a FTP outbound to move a file to an archive folder, the file gets archived but never gets deleted from the source location. Due to this the same files keeps getting processed again and again. Any ideas why its not removing from the source location???

You might want to try the option "Delete files after processing" on the Advanced tab in FTP inbound connector.

Try with the following config :-
<ee:object-store-caching-strategy name="cachingStrategy" doc:name="cachingStrategy">
<managed-store storeName="myNonPersistentManagedObjectStore" maxEntries="-1" entryTTL="20000" expirationInterval="5000"/>
</ee:object-store-caching-strategy>
Also, you are setting the payload null before your cache scope ... cache scope require the payload to determine if the response can be cached or not.
For same payload it will make a cache-hit and provide the response from cache else it will process the message and store it in cache

I've the following scenario. If for some reason the FTP upload fails (in this case I entered wrong credentials), the catch exception strategy is called correctly, but I still see the message Upload complete. in my log files.
Why does the flow continue its execution after an exception occurs?
<flow name="mainFlow" doc:name="mainFlow">
<vm:inbound-endpoint path="test" exchange-pattern="one-way" />
<choice>
<when expression="#[flowVars.fileToUpload != null]">
<set-payload value="#[flowVars.fileToUpload]" />
<ftp:outbound-endpoint host="${ftp.host}" port="${ftp.port}" user="${ftp.username}" password="${ftp.password}" path="${ftp.path.input}" outputPattern="#[flowVars.fileName]" />
</when>
<otherwise>
<logger doc:name="Logger"/>
</otherwise>
</choice>
<logger message="Upload complete." level="INFO" />
<catch-exception-strategy>
<logger doc:name="Exception occurred"/>
</catch-exception-strategy>
</flow>
Because the incoming MuleEvent is asynchronous. Try setting the processiingStrategy="synchronous" on theflow:
<flow name="mainFlow" doc:name="mainFlow" processingStrategy="synchronous">
....
</flow>
Im trying to access a value from session variable set into another flow
code:
<flow name="test" doc:name="test" >
<http:inbound-endpoint exchange-pattern="request-response" address="http://localhost:8081/services/autocomplete" connector-ref="" transformer-refs="transform" doc:name="HTTP">
</http:inbound-endpoint>
<set-variable variableName="req" value="#[message.inboundProperties['http.query.string']]" doc:name="Variable"/>
<set-session-variable variableName="message" value="test" doc:name="Set Message ID"/>
<http:outbound-endpoint host="teste.local" path="newlocation/autocomplete?#[groovy:return req.toString();]" port="8080" user="login" password="1234" exchange-pattern="request-response" doc:name="HTTP">
</http:outbound-endpoint>
</flow>
and another flow trying to print it:
<flow name="test2" doc:name="test2" >
<http:inbound-endpoint exchange-pattern="request-response" address="http://localhost:8081/services/autocomplete2" connector-ref="" transformer-refs="transform" doc:name="HTTP">
</http:inbound-endpoint>
<set-variable variableName="req" value="#[message.inboundProperties['http.query.string']]" doc:name="Variable"/>
<logger message="#[sessionVars.message]" level="INFO" doc:name="Logger"/>
<http:outbound-endpoint host="teste.local" path="newlocation/autocomplete?#[groovy:return req.toString();]" port="8080" user="login" password="1234" exchange-pattern="request-response" doc:name="HTTP">
</http:outbound-endpoint>
</flow>
But there is an error saing there is no variable set into that flow even when i first try to access the first url them i change to the seccond where it was supose to have the session.
-> mule version 3.4
Session variables need to be passed from one flow to another. They are serialized and deserialized on the event. You're setting it in the first flow and calling /autocomplete but the flow thats reading it is listening on /autocomplete2.
You cannot hit /autocomplete2 separately after /autocomplete and expect the session variable to be there as it was set on a different event. If you are looking to store state between separate flow invocations take a look at the mule objectstore module
http://mulesoft.github.io/mule-module-objectstore/mule/objectstore-config.html
And info on Mule object stores here:
http://www.mulesoft.org/documentation/display/current/Mule+Object+Stores
Some example configurations here:
https://github.com/mulesoft/mule-module-objectstore/blob/master/src/test/resources/mule-config.xml
Your flow will be something like the following :-
<flow name="test" doc:name="test" >
<http:inbound-endpoint exchange-pattern="request-response" address="http://localhost:8081/services/autocomplete" doc:name="HTTP">
</http:inbound-endpoint>
<set-variable variableName="req" value="#[message.inboundProperties['http.query.string']]" doc:name="Variable"/>
<set-session-variable variableName="message" value="test" doc:name="Set Message ID"/>
<logger message="Done #[sessionVars.message]" level="INFO" doc:name="Logger"/>
<http:outbound-endpoint exchange-pattern="request-response" method="POST" address="http://localhost:8081/services/autocomplete2" doc:name="HTTP"/>
</flow>
<flow name="test2" doc:name="test2" >
<http:inbound-endpoint exchange-pattern="request-response" address="http://localhost:8081/services/autocomplete2" doc:name="HTTP">
</http:inbound-endpoint>
<set-variable variableName="req" value="#[message.inboundProperties['http.query.string']]" doc:name="Variable"/>
<logger message="#[sessionVars.message] #[sessionVars['message']] " level="INFO" doc:name="Logger"/>
</flow>

You have defined your plaintext connection attributes (username, password, address) in magento:create-product and then you have them as application properties in magento:config. That does not really make sense, as you only need to define the attributes once (in the config element) when you use config-ref in the other elements. Since you are having a connection failure, I would guess that you have incorrect properties in the config element. Try using the attributes from magento:create-product, instead.
EDIT: I checked the WSDL for your Magento API, and it seems that you have incorrect address
Try using https://sashistore.gostorego.com/index.php/api/v2_soap/index/ instead.
EDIT2: I got the WSDL URL for Magento API v2 from the Magento documentation. See this page for explanation on how to get the address for Web services from WSDL.
