Mule using Salesforce

Mule ESB 3.6
CRUD operations on Salesforce using
Mule ESB

Objective
– Advantages of using Salesforce connector
– How to perform Create, Read, Update and Delete
operations on Salesforce

Pre-requisites
• Anypoint Studio
• A Salesforce developer account
• A security token for Salesforce

Salesforce Connector
• Salesforce connector allows Mule ESB application to connect
to Salesforce
• It supports data sense which fetches meta data information
about of Salesforce once required connection details are
specified at the connector
• It lists all objects and operations at design time using data
sense and makes development easy and rapid

Steps
• Create a Salesforce developer account
• Create a security token for Salesforce account
• Create a mule application to perform CRUD
operations

How to create Salesforce developer
account
• Sign up for a new account at http://developer.force.com/

How to generate a security token
• Sign into http://developer.force.com/, click your name in the
upper right corner, then click Setup > My Personal
Information > Reset Security Token. Then, click Reset My
Security Token. Salesforce sends your security token via email
to your registered email address

Create a mule application to perform
CRUD operations
• Create a property file
• Configure property file in your project
• Add Salesforce connector and configure the
connector details
• Configure a flow
• Run your application

• Create a property file with following details
and place it in mule_home/conf folder
#SF URL
sf_url=https://<your salesforce url>/services/Soap/u/26.0
#SF Username
sf_username=<Your salesforce account name>
#SF Password
sf_password=<Your salesforce account password>
#SF Security Token
sf_security_token=<Your salesforce security token>

Add the property file in your flow
• Click on global elements tab -> Click on create -> Type in Property
Placeholder in the filter box -> Select Property Placeholder and click on Ok
-> Type in “file:${mule_home}/conf/salesforce-config.properties” in the
location text box and click on Ok
• You should see an XML tag added under your configuration XML as below
<context:property-placeholder location="file:${mule_home}/conf/salesforce-
config.properties"/>

Add Salesforce connector in your flow
• Click on global elements tab -> Click on create -> Select
Salesforce and add property as shown below

You need to create 3 java classes as
show below
• CreateContactRequest.java
public class CreateContactRequest implements Callable {
@Override
public Object onCall(MuleEventContext eventContext) throws Exception {
HashMap<String,Object> contactSObjectFields = new HashMap<String,Object>();
// sObject is defined as a map
contactSObjectFields.put("FirstName", “YourFirstName");
contactSObjectFields.put("LastName", "YourLastName");
contactSObjectFields.put("MobilePhone", "YourMobileNo");
contactSObjectFields.put("Email", “YourEmail");
// list of sobjects to be created
List<HashMap<String,Object>> objects = new ArrayList<HashMap<String,Object>>();
objects.add(contactSObjectFields);
// map that will be placed as payload
HashMap<String,Object> payload = new HashMap<String,Object>();
payload.put("type", "Contact");
payload.put("objects", objects);
return payload;
}
}

• UpdateContactRequest.java
public class UpdateContactRequest implements Callable {
@Override
HashMap<String,Object> contactSObjectFields = new HashMap<String,Object>();
MuleMessage muleMessage = eventContext.getMessage();
contactSObjectFields.put("FirstName", “YourModifiedFirstName");
contactSObjectFields.put("LastName", "YourModifiedLastName");
contactSObjectFields.put("MobilePhone", "YourModifiedMobileNo");
contactSObjectFields.put("Email", “YourModifiedEmail");
contactSObjectFields.put("Id", muleMessage.getProperty("sObjectId", PropertyScope.SESSION));
// map that will be placed as payload
HashMap<String,Object> payload = new HashMap<String,Object>();
payload.put("type", "Contact");
payload.put("object", contactSObjectFields);
return payload;
}
}

• CreateContactResponseProcessor.java
public class CreateContactResponseProcessor implements Callable {
@SuppressWarnings("unchecked")
@Override
AcknowledgementType ack = new AcknowledgementType();
MuleMessage message = eventContext.getMessage();
System.out.println(message.toString());
// get the message payload
List<SaveResult> saveResults = (List<SaveResult>) message.getPayload();
Iterator<SaveResult> iter = saveResults.iterator();
SaveResult saveResult = iter.next();
ack.setMessageID(saveResult.getId());
if(saveResult.getSuccess())
ack.setStatus("Success");
else
ack.setStatus("Success");
System.out.println(ack);
return ack.getMessageID();
}
}

Create a mule flow with as show
below

The flow configuration will look should look like as
follows
<context:property-placeholder location="file:${mule_home}/conf/salesforce-config.properties"/>
<sfdc:config name="Salesforce" username="${sf_username}" password="${sf_password}" securityToken="${sf_security_token}" url="${sf_url}" doc:name="Salesforce">
<sfdc:connection-pooling-profile initialisationPolicy="INITIALISE_ONE" exhaustedAction="WHEN_EXHAUSTED_GROW"/>
</sfdc:config>

</flow>
<flow name="QueryContact" doc:name="QueryContact">

<flow-ref name="UpdateContact" doc:name="GoToUpdateContactFlow"/>
</flow>
<flow name="UpdateContact" doc:name="UpdateContact">
<component class="com.sfdc.requestresponse.processor.UpdateContactRequest" doc:name="UpdateContactRequest"/>
<logger message="Update Request----> #[payload]" level="INFO" doc:name="LogUpdateContactSalesforceRequest"/>
<sfdc:update-single config-ref="Salesforce" type="#[payload.type]" doc:name="UpdateSalesforceContact">
<sfdc:object ref="#[payload.object]"/>
</sfdc:update-single>
<logger message="Update Output----> #[payload]" level="INFO" doc:name="LogContactUpdated"/>
<flow-ref name="ReadContactAgain" doc:name="GoToReadContactFlow"/>
</flow>
<flow name="ReadContactAgain" doc:name="ReadContactAgain">
<logger level="INFO" doc:name="LogSalesforceReadContactRequest"/>
<sfdc:query config-ref="Salesforce" query="SELECT Id,Name,BillingStreet, BillingCity,BillingState,BillingPostalCode,BillingCountry FROM Account WHERE Id = '#[sessionVars.sObjectId]'" doc:name="ReadSalesforceContact"/>
<logger level="INFO" doc:name="LogSalesforceReadContactResponse" message="Query Output: #[payload]"/>
<flow-ref name="DeleteContact" doc:name="GoToDeleteContactFlow"/>
</flow>
<flow name="DeleteContact" doc:name="DeleteContact">
<sfdc:delete config-ref="Salesforce" doc:name="DeleteSalesforceContact">
<sfdc:ids>
<sfdc:id>#[sessionVars.sObjectId]</sfdc:id>
</sfdc:ids>
</sfdc:delete>
<logger level="INFO" doc:name="LogDeleteContactResponse" message="Delete Output-----> #[payload]"/>
<set-payload value=""CRUD Operations executed successfully. Please check the logs for details"" doc:name="Set Payload"/>
</flow>

• Now you can run the application and hit the http URL configured in your
application in browser
• It should create a contact, read the values, update the contact, read the
value and finally delate the contact from Salesforce.
• You can delete the last flow reference for delete contact if you like to see
the contact in Salesforce for your testing
• Details of the contact creation to deletion can be observed in logs
