CONSUMING SAP NETWEAVER GATEWAY SERVICES

FROM BLACKBERRY APPLICATIONS

SAP NetWeaver Gateway technology provides a simple way to interact with SAP applications through

variety of devices, environments and platforms based on market standards. The framework enables

development of innovative, people-centric solutions that bring the power of SAP business software into

new experiences, such as: social networking and collaboration environments; mobile and tablet devices;

and rich internet applications. The framework supports rapid innovation while ensuring security, integrity,

management and optimized maintenance of the core SAP systems. Completely flexible, the software offers

connectivity to SAP applications using any programming language or model without the need for SAP

knowledge by taking advantage of REST services and OData/ATOM protocols.

Note: There is added value in using the SAP OData Mobile SDK (which comes with the usage of SUP).This added value is not included when using the code snippets.

This guide provides information on how to consume SAP NetWeaver Gateway services from Blackberry

applications based on the following scenario:

The user wants to fly from New York to San Francisco.

He goes online and searches for the different flights available. He enters his search parameters: city of

origin, destination city, departure date, and arrival date (Function Import).

From the SAP NetWeaver Gateway, he receives the information for the option(s) that meet(s) his searchparameters (Get Function).

He can now select the one that suits him the most and book his flight (Create Function).

The links to access the service document and metadata document are provided the in table below.

Service

Document

http://:/sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT/

Metadata

Document

http://:< Gateway_Port>/sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT/

$metadata?$format=xml

Each service URL should contain the following information:

Gateway host

Port

SAP Client no need to specify client if connecting to the default client.

Example:

http://:/sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT?sap-client=100

To obtain information on the selected service (its properties, function imports, associations, etc.), refer to

Appendix 1, were we show the Metadata description of the RMTSAMPLEFLIGHT service.

To view the code snippets in a format that can be copied into new code, refer toAppendix 2.

The Flight service contains the following collections:

Collection URL

FlightCollection (list of flights) http://:/sap/opu/sdata/

iwfnd/RMTSAMPLEFLIGHT/FlightCollection

CarrierCollection (list of carriers http://:/sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT/CarrierCollection

BookingsCollection (list of Bookings) http://:/sap/opu/sdata/

iwfnd/RMTSAMPLEFLIGHT/BookingCollection

The operation GetAvailableFlights on FlightCollection is used to get a list of flights. The following is the URL

for the same:

http://:/sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT/GetAvailableFlights?Each collection supports some or all of the operations listed below. The table below provides the list of

operations supported and the methods that each of this operations map to respectively:

Operation Method

Create HTTP POST

Read GET

Update PUT

Delete DELETE

Prerequisites

The following tools are required for developing a Blackberry application:

Software Version

SAP NetWeaver Gateway 2.0

Eclipse 3.5

OS Blackberry 5.0

Contact your system administrator for landscape details to connect to the SAP NetWeaver Gateway system.

Building a Blackberry Application

Function Import Example

To get a list of the available flights, based on filter criteria, trigger the GetAvailableFlights function import

with cityFrom, cityTo, fromDate, and toDate parameters. The response will contain a list of flights that

meet the criteria.

Note: For more information on Function Import (also called Service Operation), refer to OData

documentation at http://www.odata.org/developers/protocols/uri-conventionsunder the Addressing

Service Operations section.

Refer to the code snippet below for details on how to do it from a Blackberry application:

1. Use the following method for executing a Function Import that returns a collection of flights.

/**

* Get available flights - provide source, destination city and date as* input.

* @param from

* @param to

* @param date

* @return* @throws IOException

*/

public String getFlightList(String cityFrom, String cityTo, String fromdate, String todate)

throws IOException

{

2. Create the URL request that will be sent.

String requestUrl = "https://:/sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT/GetAvailableFlights?cityfro

m=" + cityFrom + "&cityto=" + cityTo + "&fromdate=" + fromdate + "&todate=" + todate;

HttpConnection httpConnection = (HttpConnection) Connector.open(requestUrl);

httpConnection.setRequestProperty( "Content-Type", "text/xml");

httpConnection.setRequestMethod(HttpConnection. GET);

3. Add the basic authentication header.

httpConnection.setRequestProperty( "Authorization", "Basic " +

Base64OutputStream.encodeAsString(userpassword.getBytes(), 0, userpassword.getBytes().length,false, false));

4. Execute the request.

Note: If there is a failure in the service, throw an exception:

int status = httpConnection.getResponseCode();

if (status != HttpConnection.HTTP_OK)

{

thrownew RuntimeException("Error code: " + status);

}


7/30

Copyright/Trademark

5. Read the input stream.

InputStream inputStream = httpConnection.openInputStream();

httpConnection.close();

6.

Convert the input stream into a String

String resultAsString = new String(IOUtilities.streamToBytes(inputStream), "UTF-8");

return resultAsString;

}

To parse the properties for each entry from the feed, follow the example below:

publicvoid parsePropertiesFromFeed(String xml)

{

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

String propertyValue = null;

String propertyName = null;

try

{

DocumentBuilder builder = factory.newDocumentBuilder();

Document dom = builder.parse(new ByteArrayInputStream(xml.getBytes()));

Element root = dom.getDocumentElement();

NodeList entries = root.getElementsByTagName("atom:entry");

// iterate over entries

for (int i = 0; i < entries.getLength(); i++)

{

add(new LabelField("entry number: " + i));

Node atomContentNode = entries.item(i).getChildNodes().item(1);

If (atomContentNode.getNodeName().equalsIgnoreCase("atom:content"))

{

Node mpropertiesNode = atomContentNode.getChildNodes().item(0);

if (mpropertiesNode.getNodeName().equalsIgnoreCase("m:properties"))

{

NodeList mpropertiesList = mpropertiesNode.getChildNodes();

// iterate over entry properties

for (int j = 0; j < mpropertiesList.getLength(); j++)

{

propertyName = mpropertiesList.item(j).getNodeName();


8/30

Copyright/Trademark

propertyValue = mpropertiesList.item(j).getFirstChild().getNodeValue();

add(new LabelField(propertyName + ": " + propertyValue));

}

}

}

}

}

catch (Exception e)

{

thrownew RuntimeException(e.getMessage());

}

}

Create Example

To book a flight, trigger the HTTP POST method on the Booking Collection (with the Booking details in the

request body). Check for the HTTP response code. If the response code is 201, then the HTTP-POST is

successful. The response contains the newly created Booking ID in the bookidfield, as well as the entire

information that was part of the request body.

Refer to the code snippet below for details on how to invoke a create request from a Blackberry

application:

1. Create the entry body.

String content = "" +

2. Use the XML string to execute the method as shown below:

/**

* Books a flight according to the details provided in the body of the

* request.

*

* @param content

* the booking entry payload* @return the booking entry payload

*/

public String createBooking(String content)

{


String bookingUrl = "https://:/sap/opu/sdata/IWFND/RMTSAMPLEFLIGHT/BookingCollection";

4. Create the HTTP Post request:

String result = null;

HttpConnection connection;

try

{

connection = (HttpConnection) Connector.open(bookingUrl);


connection.setRequestProperty( "Authorization", "Basic " +

Base64OutputStream.encodeAsString(userpassword.getBytes(), 0, userpassword.getBytes().length,

false, false));

connection.setRequestMethod(HttpConnection.POST);

connection.setRequestProperty( "Content-Type", "text/xml");

connection.setRequestProperty( "Content-Length", content == null ? "0" :

Integer.toString(content

.getBytes("UTF-8").length));

Note: Make sure to add this header to post requests:

connection.setRequestProperty( "X-Requested-With", "XMLHttpRequest");

6. Add the body of the HTTP post.

if (content != null)

{

OutputStream outputStream = connection.openOutputStream();

outputStream.write(content.getBytes( "UTF-8"));

outputStream.close();

}


14/30

7. Get the response.

InputStream inputStream = null;

try

{

inputStream = connection.openInputStream();

}

catch (IOException e)

{

e.printStackTrace();

}

int resCode = connection.getResponseCode();

if (resCode != HttpConnection.HTTP_CREATED)

{


System.err.println("Server error code " + resCode);

thrownew RuntimeException("Server error code " + resCode);

Creation of Request Body for Create Method

The request body can be easily created by looking at the tags in the collections metadata. For example, the

metadata for Booking Collection provides information about the various fields (tags) that are needed for

creating a booking.

Authentication Using X.509 Certificate

The procedure above describes requests sent to the service using Basic Authentication.

If X.509 Certificate Authentication is needed, the X.509 Client Certificate should be attached to any request

sent to the service. In addition, a CA Certificate of the SAP NetWeaver Gateway server should be used for

server authentication, as part of the SSL Handshake process.

Note:OData generated proxies do not support X.509 Certificate Authentication. Therefore, the servicerequests should be sent using Java libraries which support SSL and X.509 Certificates. In addition, the

developer is responsible for parsing the service response according to the OData/SAP Data Protocols.

Prerequisites

The following tools are required for developing a Java application for Blackberry using X.509 Certificate

Authentication.

Software Version

Portecle-1.7 1.7

Make sure you have performed the following procedures:

Download Portecle.

On a Windows operating system, this can be done by downloading the Portecle-1.7.zip file and

extracting it to a selected folder.

Export the root CA Certificate of the SAP NetWeaver Gateway server into a local file. You may use anybrowser program for that. Make sure the certificate is saved in Base64-encoded format.

Store the X.509 Client Certificate (which should be attached to each request sent to the service) in a

local file. Make sure the certificate is saved in PEM format. If the certificate is saved in a different

format, you may convert it to PEM format using a converter tool, such asOpenSSL.

For example, to convert a PKCS#12 file (pfx.p12) containing a private key and certificates to PEM

format, execute the following command:

openssl pkcs12 -in .pfx -out .pem nodes

You may need to install a patch to your JRE, and set the encryption to unlimited strength depending on

Blackberry Project Configuration

To allow the code to use a CA Certificate and an X.509 Client Certificate:

1. Using the Portecle tool, import a CA Certificate to the key store of your MDS JRE.

For instructions on how to import a CA Certificate to a trust store, refer to the Blackberrydocumentation at

http://docs.blackberry.com/en/admin/deliverables/20839/Configuring_how_apps_trusted_conn_to_web

_servers_268738_11.jsp,under the "Add a retrieved certificate for a web server to the key store"

section.

For instructions on how to import a CA Certificate to a trust store refer to Portrcle documentation at

http://portecle.sourceforge.net/import-trusted-cert.html.

2. Configure the simulator to use the X.509 certificate.

a. Configure the simulator to use a computer file system as a microSD card as described in the

Blackberry documentation at:

http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800792/801083/H

ow_To_-_Use_a_computer_file_system_as_a_microSD_card.html?nodeid=1417343&vernum=0,

under the "How To - Use a computer file system as a microSD card Article Number: DB-00654"

section.

b. Save the X.509 Client Certificate in the simulators SD Card library.

c. Run the simulator.

d. From the simulator, browse for the X.509 Client Certificate located in the SD card library and click

it. The simulator prompts you to install it.

e. Install the X.509 Client Certificate.

Read Example

Refer to the code snippet below for details on how to send a request to a Java Blackberry application using

X.509 Certificate Authentication:

1. Open https connection.

HttpsConnection sc = (HttpsConnection) Connector.open(url,

Connector.READ_WRITE);

InputStream in = sc.openInputStream();

2. Read the response.

while ((inChar = in.read()) != -1) {//append incoming characters to the bufferinBuffer.append((char)inChar);

response = inBuffer.toString();}

3. Close the inputStream.

in.close();

4. Close the HTTP Connection.

sc.close();
