TWS Workshop for NCB

For NCB Bank

What are Web Services?

 Software can be accessed remotely using different XML-based

application that languages

 It doesn’t matter...
• what kind of computer sends the message or on which operating system
it is running
• where in the world the client is sending the message from
• what language the software that the client is running on is written in
• to the client what type of SOAP processor is running on the server

 Key Components
• SOAP
• specifies XML grammar for sending and responding to messages

For NCB Bank 2

Web Services: Key Components

• XML and XML Schema (Parts 1 & 2)

• language that all web services languages are built on

• HTTP
• standard that facilitates transfer of SOAP messages and WSDL
documents between computers
• Advantage: permitted through Firewall (unlike CORBA/DCOM)

• WSDL
• Specification that tells us how to describe a piece of software in
terms of the method calls it responds to. Described in abstract way,
independent of programming language
• Also contains concrete details of how to make the connection:
• Method Calls
• Parameters it accepts
• Responses it will send back
• Protocols it can process
• Data format specifications it can accept
• URLs for the service

T24 Business Service Definition

T24 Service Landscape

Business Services Business services are pre-packaged

(EB.SERVICE) in Model Bank.

Business Operations Business Operations are transactions

(PW.ACTIVITY)
with a defined function or query.
Custom operations can be defined in
T24 in the same way as input
screens. This includes new T24
Transactions Queries applications.

JCA Architecture

 Java EE Connector Architecture (JCA)

• Java-based technology solution for connecting application servers
(Jboss) and Enterprise Information Systems (T24 on TAFC) as part of
an Enterprise Application Integration (EAI) solution.
• Requires a functionally-rich Application Server.
• JCA will not function under a simple web server like Tomcat.

 Resource Adaptor
• A system-level software driver, which is used by a Java application to
connect to an EIS (T24 on TAFC).

 Why JCA?
• Before JCA was defined, no specification provided a standard
architecture for integrating heterogeneous EIS systems.
• Enables an EIS vendor (Temenos) to provide a standard Resource
Adapter for its EIS (T24).
• Single resource adapter can plug in to any application server that
supports JCA. (JBOSS, WebSphere, WebLogic)

For NCB Bank 6

JCA Architecture

 Benefits
• Independence from proprietary Temenos Connectivity Software
(TCServer)
• Simplification of Browser, ARC-IB and TWS deployment and
configuration
• Availability of standard message monitoring and integration tools
• Clients have existing configuration expertise.

 TOCF(EE) supports two architectures:

• AGENT:
• Allows TWS to connect directly to T24 using the TAFC JCA and the
jbase_agent
• JMS
• Enhanced resilience and load balancing
• Both architectures:
• Lookup the TAFC JCA
• Call OFS.BULK.MANAGER as the entry point to T24

Success request completed successfully

TWSError error occurred in TWS web application
T24Error T24 error encountered
T24Override Override condition encountered
T24Offline T24 System is offline

 transactionId
• the T24 transaction id for the completed request

 messages
• list of all success / error messages returned from T24 or TWS web
application

 An AA Web Service may update multiple T24 applications:

• multiple Status and Business Objects returned.
• The successIndicator of each Status object should be checked

For NCB Bank 25

Custom Routines

 Invoke T24 Subroutine via a Web Service

• Not defined in T24 service landscape (PW.ACTIVITY & EB.SERVICE)

Example OFS request:

SIGNON.WORK.BALANCE,,INPUTT/123456,,100485

SUBROUTINE SIGNON.WORK.BALANCE(CUST.ID,WORK.BALANCE)
$INCLUDE T24.BP I_COMMON
$INCLUDE T24.BP I_EQUATE
$INCLUDE T24.BP I_F.ACCOUNT

WORK.BALANCE = 0
CALL F.READ('F.CUSTOMER.ACCOUNT',CUST.ID,R.CUSTOMER.ACCOUNT,'',YERR1)
LOOP
REMOVE ACCT.ID FROM R.CUSTOMER.ACCOUNT SETTING ACCT.POS
WHILE ACCT.ID : ACCT.POS
R.ACCT = ''
CALL F.READ('F.ACCOUNT',ACCT.ID,R.ACCT,'',YERR2)
WORK.BALANCE += R.ACCT<AC.WORKING.BALANCE>
REPEAT
RETURN
END

For NCB Bank 26

Custom Routines: Steps required (Java)

 Design
• Define the Web Service field parameters & data type (Request/Response)
• Define the inputs/outputs for the T24 routine
• Decide the message format to be passed
• OFS format or custom design
 T24
• Write the Business Operation (T24 subroutine)
• Expose it in PGM.FILE as a type ‘S’ubroutine

 Eclipse
• Modify beans.xml: define the class to be used for the Web Service
• Create a custom source folder
• Create a custom package
• Write a Request class and a Response class with annotations
• Write the Web Services implementation class
• Generate and deploy (standard procedure)
