I am facing a problem while connecting with the QuickBooks connector.
My keys are correct. Didn't find any solution how to solve this? Can any one help me?
UPDATE
Following is my flow
<flow name="Authorize">
<!-- INBOUND ENDPOINT -->
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" doc:name="HTTP"/>
<quickbooks:auth-user config-ref="Quickbooks_Online" accessTokenUrl="https://oauth.intuit.com/oauth/v1/get_access_token" authorizationUrl="https://appcenter.intuit.com/Connect/Begin" callbackUrl="http://localhost:8090" requestTokenId="#[groovy:message.getSessionProperty('requestTokenIdentifier')]" requestTokenUrl="https://oauth.intuit.com/oauth/v1/get_request_token" doc:name="Quickbooks Online"/>
</flow>
<flow name="GetAccessToken">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8090" doc:name="HTTP"/>
<quickbooks:get-access-token config-ref="Quickbooks_Online" doc:name="Quickbooks Online"/>
<quickbooks:get-object config-ref="Quickbooks_Online" accessTokenId="#[groovy:message.getSessionProperty('accessTokenIdentifier')]" type="ACCOUNT" doc:name="Quickbooks Online"/>
<json:object-to-json-transformer doc:name="Object to JSON"/>
<logger message="O-JSON #[payload]" level="INFO" doc:name="Logger"/>
</flow>
Now I got OAuthCredential error..
Message : Failed to invoke getObject. Message payload is of type: OAuthCredentials

This error:
The user token could not be retrieved from the Object Store using the key
tells you that you have not authenticated the connector correctly.
It's as if you haven't captured a valid token, either via OpenID or OAuth. Make sure to use one of these two methods to authenticate before calling the greenropetestFlow1 flow.
Read the authentication guide for the QuickBooks connector here: http://mulesoft.github.io/quickbooks-connector/online/authentication.html
I was facing the same issue, it seems the connector is out of the date and those authentication methods are just not working, no body has push changes since a couple of years.
I wrote a solution here:
https://yucelmoran.com/2018/02/12/authorization-process-for-quickbooks-online-using-mule-no-connector/
hope it helps, it's maybe just a temporally solution..

i need to send json to a web service and getting the response in json format.
so firstly i have a http connecter which receive data and then i need a datamaper to map the json that i get to the web service. in a second flow i put another http connecter which listen to the web service and get the response. actually what i need is an element who can replace the datamaper because i'm working with the community version. so if there is any example of code any tutorial, i would be grateful.
First flow:
<flow name="Flow1">
<http:inbound-endpoint exchange-pattern="request-response"
host="localhost" port="8082" doc:name="HTTP"
contentType="application/x-www-form-urlencoded" path="getDetails" />
<json:json-to-object-transformer
returnClass="java.lang.Object" doc:name="JSON to Object" />
<set-session-variable variableName="tkn"
value="#[message.payload.token]" doc:name="token" />
<set-session-variable variableName="msg"
value="#[message.payload.msg]" doc:name="message" />
<logger message="#[sessionVars['tkn']]" level="INFO" doc:name="Logger" />
</flow>
You can either do your own mapping in a custom component or use a framework like Smooks to do the transformations. If you choose the latter you can check out this blog post. HTH.
Rajeun,
Refer the below link if that helps.
http://www.mulesoft.org/documentation/display/current/JSON+Module+Reference
You need to follow following steps :-
1. Extract the data from your input Json request and store in variables.
2. Now, if your external service is a SOAP, then you can create a SOAP request using XSLT example :- http://bushorn.com/xml-to-xml-transformation-in-mule/
3. If your external web service is a REST, you can create the JSON request for that service using Mule Expression transformer example :- http://bushorn.com/json-to-json-transformation-in-mule/
I have a requirement to pass an object to an HTTP connector (Not sure if I can use any other connector). The next step is convert an object to a CXML and make an outbound end point call to another API, get the response and convert it another java object. I am very new to Mule and need some inputs on this. Any pointers would be very helpful.
Can someone give me some good points where we have good links for mule implementation examples (apart from Mule in Action)
EDIT: code from OP's comment below
<flow name="object_serialization.mflowFlow1" doc:name="object_serialization.mflowFlow1">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" doc:name="HTTP"/>
<component class="SerializeObject" doc:name="Java"/>
<serializable-to-byte-array-transformer doc:name="Serializable to Byte Array"/>
<http:outbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" method="POST" doc:name="HTTP"/>
</flow>
You can achieve your goal with Mule:
On the client side:
Serialize the Java object with serializable-to-byte-array-transformer
HTTP POST it with an http:outbound-endpoint
On the server side:
Receive the HTTP POST with an http:inbound-endpoint
Deserialize the Java object with byte-array-to-serializable-transformer
This assumes the Java object implements java.io.Serializable, which should be the case since you stated you want to use Java serialization. This also assumes that the necessary Java classes are available on the classpath of both client and server Mules.
I have tested Twitter and LinkedIn and I seem to be able to get these working eventually, but I just cannot find enough material to get the Google connectors to work. When using the Google Calendar connector I am trying to collect the token with - #[flowVars['tokenId']] but the value always comes out as null. Am I doing something wrong? Can someone please help?
Thanks,
Ash.
Answered my own question for anyone else struggling with the same issue -
Managing OAuth Tokens (optional)
Configure ObjectStore
To keep data persistent you need to store it somewhere, it is recommended you use ObjectStore for this. Install an ObjectStore connector. Configure it like this in your application:
<objectstore:config name="ObjectStore" doc:name="ObjectStore" />
Storing Tokens After Authorization
After the authorization dance is done, the accessTokenId for the service you are invoking is available as a flow variable called OAuthAccessTokenId. You must persist this ID so you can use it in future invocations of your connector. This example shows how to store this variable into ObjectStore under the key accessTokenId.
<flow name="authorize-google" doc:name="authorize-google">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" path="authorize" doc:name="HTTP"/>
<google-contacts:authorize config-ref="Google_Contacts" doc:name="Authorize GContacts"/>
<objectstore:store config-ref="ObjectStore" key="accessTokenId" value-ref="#[flowVars['OAuthAccessTokenId']]" overwrite="true" doc:name="ObjectStore"/>
</flow>
Using Your Access Token
Any invocation of your connector must load the access token from ObjectStore and reference it. This example shows loading it from ObjectStore and checking if it was set, before proceeding.
<enricher target="#[flowVars['accessTokenId']]" doc:name="Message Enricher">
<objectstore:retrieve config-ref="ObjectStore" key="accessTokenId" defaultValue-ref="#['']" doc:name="Get AccessToken"/>
</enricher>
<expression-filter expression="#[flowVars['accessTokenId'] != '']" doc:name="Is Access Token Set"/>
Once accessTokenId is available as a flow variable, you can reference it in your connector operations:
<google-contacts:get-contacts config-ref="Google_Contacts" accessTokenId="#[flowVars['accessTokenId']]" />
More details here - http://www.mulesoft.org/documentation/display/34X/Using+a+Connector+to+Access+an+OAuth+API

I am experimenting with exception strategies and came across the following config.
If I invoke one flow from another using synchronous vm endpoints and do not catch exceptions in the callee flow. The caller flow exception strategy does not get invoked, but instead the callee flow adds an exceptionPayload.
I would assume if there is an exceptionPayload that the caller flow exceptions strategy would get invoked. But it doesn't. Is this a feature or a bug?
<flow name="main" doc:name="main">
<poll frequency="60000">
<set-payload value="main"></set-payload>
</poll>
<vm:outbound-endpoint address="vm://private" exchange-pattern="request-response" />
<logger level="ERROR" message="After private #[exception]" />
<catch-exception-strategy>
<logger level="ERROR" message="Exception caught in parent." />
</catch-exception-strategy>
</flow>
<flow name="private">
<vm:inbound-endpoint address="vm://private" exchange-pattern="request-response" />
<logger level="ERROR" message="private" />
<null-component></null-component>
</flow>
Also I can access the exceptionPayload via MEL using #[exception] but not via #[message.exceptionPayload]. Is there a reason why you cannot access it this way in Mule? I can see it on the DefaultMuleMessage.
Mule is a message oriented platform therefore, by design, exceptions are contained within flows (not sub-flows) and get propagated as a specific message payload.
MEL works on context objects: here is the MessageContext object API where, as you see, there is no exceptionPayload field.
I need my Mule application to process periodical requests (for example, my application will send requests to a service every 5 seconds and process responses from this service).
There is a Quartz trigger and transport built into Mule ESB. It does exactly what you want, initializing flows at a given interval or CRON expression.
Very comprehensive documentation can be found here.
An alternate solution would be using <poll/> and configuring frequency attribute in it
Reference :-https://developer.mulesoft.com/docs/display/current/Poll+Reference
example:-
<flow name="test1" doc:name="test1" processingStrategy="synchronous">
<poll frequency="1000" doc:name="Poll">
<set-payload value="Polling started at particular interval !!!" doc:name="Set Payload"/>
</poll>
<logger message="#[payload]" level="INFO" doc:name="Logger"/>
</flow>
