When you need to extend your SaaS application you may use PaaS solutions to do it!
In this blog post I will use Oracle Mobile Cloud Service (MCS) and Oracle Mobile Application Accelerator (MAX) to create a mobile application for my Oracle Sales Cloud.
Download the packages: paas4saas-with-mcs-and-max.zip.
First of all we need to create a new Mobile Backend.
Go to Menu > Applications > Mobile Backends.
Click “New Mobile Backend” button to create a new Mobile Backend and name it as SalesMB.
To create a new Connector, go to Menu > Applications > Connectors.
Click “New Connector” button to create a new SOAP Connector and name it as SalesConn.
Don’t forget to provide the WSDL of ContactService.
Click Next twice.
Select “oracle/http_basic_auth_over_ssl_client_policy” and add a new csf-key.
Click Save and then click Select.
Click Save and then click Close.
To create a new API, go to Menu > Applications > APIs.
Click “New API” button to create a new API and name it as SalesAPI.
In Security, disable the “Login Required” option.
In Schema, click “New Schema” button.
Use the following code to create 4 schemas: contactBase, newContact, contact and contactList.
contactBase
{
"$schema": "http://json-schema.org/draft-04/schema#",
"id": "contactBase",
"type": "object",
"allOf": [
{
"properties": {
"PartyId": {
"type": "integer"
}
}
},
{ "$ref": "newContact" }
]
}
newContact
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"id": "newContact",
"allOf": [
{
"properties": {
"FirstName": {
"type": "string"
},
"LastName": {
"type": "string"
}
}
}
]
}
contact
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"id": "contact",
"allOf": [
{ "$ref": "contactBase" },
{
"properties": {
"CreatedBy": {
"type": "string"
},
"CreationDate": {
"type": "string"
},
"LastUpdateDate": {
"type": "string"
},
"LastUpdatedBy": {
"type": "string"
}
}
}
]
}
contactList
{
"$schema": "http://json-schema.org/draft-04/schema#",
"id": "contactList",
"type": "array",
"items": { "$ref" : "contactBase" }
}
Click Save.
In Endpoints, click “New Resource” button and create two endpoints: contacts and contact/{id}.
Click “Methods” link of contacts endpoint and add a new GET method.
In Request section, add a new Parameter and name it as “q”.
In Responses section, add a new response.
In Body section, add a new Media Type.

"LastName": "Dunbar"
},
{
"PartyId": 100000000409233,
"FirstName": "Lisa",
"LastName": "Jones"
},
{
"PartyId": 100000000409251,
"FirstName": "Bala",
"LastName": "Gupta"
}
]
Click “Add Method” button to add a new POST method.
In Request section, go to Body section and add a new Media Type.

"LastUpdateDate": "2016-10-06T10:39:17.167Z",
"LastUpdatedBy": "LISA.JONES"
}
Click Save and go back to Endpoints.
Click “Methods” link of contact/{id} endpoint and add a new GET method.
In Responses section, add a new response.
In Body section, add a new Media Type.

In Implementation, click “JavaScript Scaffold” button to download the implementation archive.
Unzip the package, open the package.json file and replace its content with the following code:
{
"name" : "salesapi",
"version" : "1.0.0",
"description" : "API for Sales Mobile",
"main" : "salesapi.js",
"oracleMobile" : {
"dependencies" : {
"apis" : { },
"connectors" : { "/mobile/connector/SalesConn": "1.0" }

}
Open the salesapi.js file and replace its content with the following code:
/**

* @see {@link http://expressjs.com/3x/api.html#app}
*/
/**
* Mobile Cloud custom code service entry point.
