How to use OData service exposed via Integration Gateway (on-premise) with SAP Web IDE Cloud

Hello Developers,

Well, I heard a lot about SAP Web IDE and thought of getting my hands dirty. Here, I am trying to use OData service exposed via Integration Gateway (on my local machine in SAP Mobile Platform 3.0) with SAP Web IDE cloud version.

Never heard about Integration Gateway?

Tools required: SAP Mobile Platform 3.0 SP04, Eclipse Kepler with SAP Mobile Platform Tools plugins added, SAP HANA Cloud Connector

I have already exposed one of the publicly available Article SOAP web Service into OData services via Integration gateway in SMP3. (Ref link)

This is how it looks like:

Setting up SAP HANA Cloud Connector

Prerequisite: Download SAP JVM for Windows sapjvm-7.1.024-windows-x64.zip or JDK 1.7

Set Env variables JAVA_HOME : C:\Program Files\Java\jdk1.7.0_67

PATH: C:\ProgramFiles\Java\jdk1.7.0_67\bin;C:\WINDOWS\system32;C:\WINDOWS;

Steps:

1. Download HANA Cloud Connector from SAP Development Tools for Eclipse (sapcc-2.4.3-windows-x64.zip)

2. Extract the downloaded zipped file. Run go.bat command

3. Once done, run https://localhost:8443/run it in a browser

Don't close command prompt window as per step #2

As i was trying to install SAP HANA Cloud Connector on Windows 8.1 OS and as per official information it doesn't support. As a workaround have tried copying sapscc20jni.dll file from auditor folder at sapcc-2.4.0-windows-x64 into Windows\System32 (Reference)

(User Name: Administrator, Password: manage (default))

4. Choose Installation type: Master (Primary Installation)>Apply

5. Change the login password

6. Set up Initial Configuration (for more info: check http://account.hanatrial.ondemand.com/)

Enter proxy details if any.

This is how it looks like: Status :CONNECTED

7. Since OData service has been deployed on my local machine and to access on-premise resources from cloud platform, I need to open secure connection between on-premise network and cloud. I need to make sure what kind of resources I want to expose from on-premise to SAP HANA cloud system, for that go to Access Control

Add system mapping:

Parameter	Value
Virtual Host	Any name of your choice
Virtual Port	Any number of your choice
Internal Host	SMP server host name ('jk' in my case)
Internal Port	Port on which OData URL (Exposed via Integration Gateway) is listening (https://jk:8083/gateway/odata/SAP/ARTICLESERVICE;v=2/)
Protocol	HTTPS
Back-end Type	There is no option to related to SMP and Integration gateway so selected 'SAP Gateway'

8.Now, I want to decide which resource path I have to select

As you can the green icon (state of each entry)

Setting up SAP HANA Cloud Platform

It's time to set up SAP HANA Cloud account and have to create destination to exposed resources in SAP Mobile Platform server.

9. Login to SAP HANA Cloud Platform> Cockpit (Requires SCN username and password to login)

Create a new destination >Save

URL:https://virtualhost:virtualport (as per step #7)

Proxy Type: As OData service resides on on-premise system

Authentication: Basic Authentication (Credentials to access Odata URL: smpAdmin, s3pAdmin)

Additional Properties:

WebIDEEnabled	true
WebIDESystem	IGWDestination
WebIDEUsage	odata_gen

Value for the parameter WebIDEUsage is important otherwise you won't be able to pick your destination from the Service URL combo box when creating a new project with the template wizard. (Step #14)

In general, the value for the parameter WebIDESystem is SID of the gateway system but in case of SMP (Integration Gateway) it's value doesn't need to be anything special. Normally, in order to see the destination working, i have assigned to the webIDESystem the same string used for the destination name. i.e. IGWDestination
