ABSTRACT
In continuation of research work based on service orientation of monolithic legacy
software, the work presented in this paper is for the development of framework for service
orientation of monolithic legacy software after completion of phases of software analysis,
service understanding and extraction from monolithic code. The work presents the framework
with steps of further development of platform for web services, developing web services and
application of service oriented reengineering techniques for development intended target
system.
Keywords: MLS, Reverse Engineering, SOA, Web service, Wrapping, WSDL.
I. INTRODUCTION
The proposed framework for design and development of loosely coupled service
oriented system with integration of some specific service component developed from legacy
is facilitated by the methodologies of service oriented reengineering. The heritage monolithic
legacy software need to be redeveloped into a target system which is made up of a set of
loosely coupled web services, as the project is for the service orientation task, service
oriented software reengineering is applied here with other redevelopment methodologies for
service oriented development of monolithic legacy software. As a result this framework can
support the developer, designer and analyst to reengineer the tightly coupled monolithic
system to loosely coupled service oriented system.

II. LITERATURE SURVEY
Chung et al. [1] undertaken a project in which they applied a legacy theorem for
proof checking and derivation tool called Bertie3 which supports the development of
system reengineered to SOA, and developed a Service-Oriented Bertie (SoBertie) tool
which provides the key competence of Bertie3 as web services.
Chung et al. [2] presented service oriented software reengineering methodology
designed for applying SOA to legacy systems. It is concluded from three participant
service models as, (1) 4+1 view model [3], and (2) RACI charts [4], (3) Service oriented
reengineering.
Distante et al. [5] presented Ubiquitous Web Applications Design Framework
(UWA) for designing of legacy applications for web oriented application and further
presented its extended version as Transaction Design Model (UWAT+).
Chen et al. [6] presented an approach for identifying the features of legacy
program for service oriented design and further construction of service oriented features
with their implementation.
Cuadrado et al. [7] proposed a very useful methodology for the development and
recovering of legacy architecture in service oriented perspective. It uses three step
approach containing architecture recovery, developing orientation plan, and its execution.
III. FRAMEWORK DEVELOPMENT CRITERIA
The proposed framework is supposed to satisfy following identified criteria:
1. The framework is to developed for reengineering, development, wrapping and
integration of services from monolithic legacy;
2. Monolithic legacy is main application domain of framework ;
3. Cost effective and worthwhile application of framework;
4. Applicability for checking and composition of services;
5. Evaluation for required changes in existing system target system acceptance;
6. Minimizes tools support;
7. Maximum coverage on development task;
8. Implementation and validation: The framework must have to satisfy the
evaluation and validation parameters with its implication.
IV. FRAMEWORK DEVELOPMENT
Proposed framework consisting of four steps is depicted in following Fig. 1, details of
these steps are given in following sections.

4.1 Design of Web Service Platforms
The platform for design of services and implementation is Microsoft .NET, WSPs
must be implemented through HTTP that provides platform for web service message
exchange system as SOAP, it can also use some other message passing system such as MIME
over SMTP[8], which also support for security, availability, standardization and routing of
web messages. Fig. 2 depicts the web service platform consisting of SOAP processing,
message handler, registry and related components.

This platform allows web service reengineering task objects to add and customize more target
system functionalities.
4.2 Web Service development:
Web service development process consisting of four major set of activities as depicted
in Fig. 3 are following:
4.2.1 Service recovery;
4.2.2 Service wrapping;
4.2.3 Service availability;
4.2.4 Service oriented reengineering.

These set of activities are briefly described and discussed in the following sections:
4.2.1 Service recovery
To recover the services from existing legacy code base it is useful to check the
worthwhile for development process. The recovery process will undertake the investigation upon
the monolithic program to search the reusable functional code and convert them as service. As it
is observed in the PL/I, C, and COBOL code that the service providing functions are scattered in
many blocks within the functional routine [9]. Once the code block statements containing service
definition are identified then extract the code block which may be an enumerated data type,
abstract data type, procedure or a COBOL paragraph then it has to be reassembled as a separate
module with its own services.

4.2.2 Service wrapping
The tool SoftWrap is applied to automate service wrapping developed from monolithic
code, the process include WSDL interface description. The extracted services are assigned to
object wrapping component. It will help the automated manipulation of monolithic code to be
effective wrapping. The procedure applied at this stage is depicted in fig. 4.

4.2.3 Service availability
The third step of the development framework is to make available the web service for
further reengineering task. The availability of service includes for example on the server there
is a scheduler responsible for the message exchange and identify which service has to process
and forward to WSDL content from the wrapped services modules, once the wrapped
services are available for execution then it can perform the desired function and then are
ready to take the part in the further reengineering based development of target service
oriented system.
4.2.4 Service oriented reengineering
Fig. 5: SOR methodology
Service oriented reengineering consist of two main processes: reverse software
reengineering and forward software reengineering as shown in the fig. 5. The reverse
software reengineering process undertake the monolithic code generated services to develop
target system the process begin with stakeholders input under the SOC perspectives and then
forward software reengineering process conceptualize the target system after collecting all
services, wrap services, necessary documentation.
V. CONCLUSION
The service oriented development of monolithic legacy program is a procedural
activity containing several useful phases and application of conceptual and automated tools
support. The work presented in this paper describes one of the activities of all those
development phases, which mainly describe through a framework the service oriented
development of monolithic legacy software. The work concludes that SOD can be performed
successfully by implementing the activities suggested and applied in this paper.
