Call Salesforce web service using cloud adapter

In order to create an account in Salesforce follow the following steps
Open https://login.salesforce.com/
And create a new account.
Once account is created ,Rest the Security token for your Salesforce account.
This step is required as the security token is used along with password to connect to Salesforce from weblogic server.
To reset your security token follow below steps:
At the top of any Salesforce page, click the down arrow next to your name. From the menu under your name, select Setup or My Settings—whichever one appears.



From the left pane, select one of the following:
If you clicked Setup, select My Personal Information | Reset My Security Token.
If you clicked My Settings, select Personal | Reset My Security Token.



Click the Reset Security Token button. The new security token is sent via email to the email address on your Salesforce user record.

Next is to download the certificates for the cloud service

In order to Generate certificates of Salesforce to be used in Weblogic Server do the following steps
Login to Salesforce.com
There you will get a lock icon. Click on that and it will give you certificate information.





Click on Certificate information and go to Details tab as shown below




Select Copy To File. This will open up a new wizard to export the certificates




Select Base 64 encoding



Save it to your local machine. The name provided here for Certificate is SalesForceCA



Make sure to download intermediate certificate if there are any. One such intermediate certificate is shown below.



Make sure that all the chain of certificates are downloaded.

Once all the certificates are downloaded, the next step is to import them in weblogic server

Once you have the certificates with you can import these certificates in to the keystore of weblogic server.
Login to your weblogic server.
http://host:port/console
Navigate to your ServerAdmin ServerKeystore and check out the location for the DemoTrust Keystore as highlighted below




Once you are aware of the path for key store. Navigate to the location in command prompt and use the following command to import the certificate in the key store.
keytool -import -trustcacerts -alias SalesForceCA –file -keystore DemoTrust.jks -storepass DemoTrustKeyStorePassPhrase
Here SalesForceCA is the name of the certificate that you have downloaded.



When asked to import the certificate Say yes. Validate if the certificates are getting imported correctly



You can use the following command to validate if the certificates are imported successfully or not.
keytool –list –keystore DemoTrust.jks -storepass DemoTrustKeyStorePassPhrase





Create authentication key

Once the certificates are imported to the Keystore of weblogic , lets create a authentication key that will be used during design time to connect to the salesforce.
Login to the em console
http://host:port/em
Then Navigate to the following path
Weblogic DomainYour Domain
Right Click on your domain.
Go to Security and select Credentials as shown below.





Once you are in Credential page.
Create a new Map




Name the Map as SOA




Select the newly created MAP and click on Create Key.




Give Key name as SalesForceKey.
Select Type as Password
UserName – User name for your Salesforce account.
Password – The password has to be formed in following way.
If your password for Salesforce account is abc and the security token is xyz
Then the Password that you will pass in authentication key is abcxyz
i.e. your Salesforce password+Security token will be the Password in Authentication key.



Say ok an now you can go back to the Credential store and validate if the key is created or not.



Once authorization key is created, we need to have the enterprise wsdl to create a session and call business services in the Salesforce

In order to connect to Salesforce at design time from Jdeveloper we need to download the Enterprise WSDL from the Salesforce.
To download the Enterprise WSDL
Login to Salesforce.com
Go to Set up
In the left hand side
Under Build Expand the Develop tab
Go to API and click on Generate Enterprise WSDL as shown in diagram



It will open up the WSDL file in a browser as shown below



Save the WSDL file to your local Machine. This will be used later while making a connection to Salesforce at design time in Jdeveloper.

Once enterprise wsdl is downloaded the next step is to register the ip address in Salesforce

When a user tries to access Salesforce.com via a new IP address or machine, Salesforce.com requires a verification code to be entered for the user. This code is mailed to the user’s registered e-mail address. To overcome this issue, a list of IP address ranges can be set for all users from which they can always log in without facing such issues.
In order to register your ip address do the following steps
Login to Salesforce.com
Go to Set up
Security ControlsNetwork Access
Specify your ip address range as shown below.




Now all the configuration is done , only job is to create a bpel process to call any Salesforce service using Cloud adapter provided by Oracle Jdev 12c
