Service enable existing RPG code non-invasively

Hariprasadkh — Mon, 28 May 2012 07:53:23 +0000

G’day,

Appreciate any viewpoint on the ‘best’ tool/technique for exposing the existing RPG code as services, so that it can be consumed by Web interface and/or mobile interface (along side Green screen). This has to be non-invasive; without touching the code.

Also appreciate any drawback of JTOpen solution.

Thanks & Regards

Difference between clientserver, object oriented architecture (OOA) and SOA???

Hi all. What are the differences between clientserver, object oriented architecture and SOA architectures when I use them as architectures for building online shopping center If we say that SOA is the best; so what are the benefits it can offer to my online shopping centre Vs clientserver, object oriented architecture (OOA).

Formal description of non-functional properties in SOAs

Phmarcy — Wed, 09 Jun 2010 11:29:45 +0000

Hello,
I am currently doing a Masterthesis on the topic “Formal description of non-functional properties of services in SOAs”, and in this context I am looking for information about how ESBs deal with non-functional or quality (QoS) aspects in practice.

More precisely, I’m interested in models and formats for the description of caracteristics of services such as price, answer time, availability, security, popularity… I can imagine the following use cases for example:

1) Creating an SLA (Service Level Agreement) between a service provider and a user, to express guarantees on QoS and make sure that they are observed

2) Making easier the choice of a service at designtime for a particular task, in order to optimize the ratio cost/QoS

3) Deciding at runtime whether a service should be called, depending on dynamic parameters (e.g. depending on the answer time for time-critical tasks), or choosing dynamically a service among several preselected ones, that fulfill equivalent functions

4) Selecting services automatically (based on their non-functional properties) at designtime to fulfill the different tasks of a business process, and reconfiguring the mapping task/service automatically at runtime to reflect change in the QoS parameters of the services

My first question is:

Which of these scenarios are realistic? Which actually happen in reality?
I guess 4) is unrealistic, since semantic technology is not mature enough to allow automatic matching of services for particular tasks.

My second question concerns the description formats.

Several formats have been developed (e.g. WSLA, WS-Agreement, WS-Policy for Web Services), but as far as I know, none has established itself as a de facto standard.

What formats are used in practice? (I assume that non-functional caracteristics are actually dealt with, since they play an important role) Proprietary formats, that are developed by the ESB vendors? And why isn’t there any widely accepted standard like WSDL and BPEL for functional description?

Thank you for your help and opinion.

Difference between SOA and CBSE

Moh22esf — Fri, 13 Nov 2009 17:24:53 +0000

I’m researching about service identification and specification in SOA What
is the difference between SOA and CBSE?What’s difference between service
and component?I know component contains some services but for
identification of them the path is the same.
I don’t know ,can I
say my research is about Service Identification in SOA and then refer
to researches about CBSE .Then someone might ask me what is difference
between SOA and component based software engineering?
