We have two distinct agile teams, each working on separate, but related, applications. Each team has, until now, been able to work in an independent fashion (distinct code bases, persistence stores, sprints, backlogs etc). Recently, product management decided that these applications will become even more closely integrated. On a side n...
I'm a .Net developer by trade, but have done open source development in the past for fun. I need recommendations on which open source languages work particularly better (or even better yet, stable) than others. At home I'm developing sites on LAMP servers and prefer PHP and Python. Are either of those well suited for remote data/method...
Hi, We are trying to build a Tuxedo adapter in Weblogic 11g to connect to Tuxedo 6.5. Does anyone know any good tutorial out there that can show us how to do this ? We found a some tutorials in Oracle website but unfortunately the tutorial files are not downloadable (broken links): https://tuxedo-connector.samplecode.oracle.com/index....
What is the fastest way to create a list of RESTful services from data structure or simple XML files? (even with configuration files.) Is there any tools that can read a DB or a Python/Java/.Net class and generate RESTful services? Prefer something that runs on Apache or Tomcat. Programming language is not a concern, I just need to...
For a government contract we will be proposing to build a traffic monitoring architecture. We will have the following components: Video camera's set up around the area of interest. The cameras will be aware of their location and orientation and viewing parameters. A GIS map server which can be queried for streets, building, etc. An al...
My current architecture is a nice fit for SOA. The services are written using WCF, and everything is .NET (no interoperability required). To start off with I was hosting the WCF services inside a Windows Service with ServiceHost. But now the number of services is growing and I am reconsidering the choice to have them as separate Windo...
When looking at SOA (Service Oriented Architectures) the main problems seems to be distributing a services load across multiple hosts and then managing these hosts (taking hosts off line or adding new hosts) When one service talks to another it should not need to know any host information (at the application level). Rather the SOA Envir...
First off, apologies if this question has been asked before but I couldn't find anything that answers this directly. Here's my problem. I've inherited a product which has been designed to be so flexible that populating pretty much every combobox and textblock on the (silverlight) form requires a service request. Some of the screens ta...
It's possible (even probable) that I'm just not fully grokking the concept of a "unit of work." Basically, I see it as sort of a broad transaction used in an object-oriented environment. Start the unit of work, interact with the objects, commit or roll back. But how does this break down to the actual transactions on the data stores be...
Hi , I have a webservice [call it S1] exposed and clients call that service and get back response.So good so far. I have to change my WSDL a bit [for some very odd reasons] but i dnt want clients to see the change. So my idea is to intercept the soap request somewhere b/w server and client and interceptor should modify the soa...
Disclaimer : I am a novice in WCF and SOA :P I am just starting out on these, I have a theoretical doubt : Client A has called a service and the logic is currently executing on the server. While the logic is executing, another call from Client B comes in for the same service. At this point what happens to the logic that is being ex...
Hi, I am an undergraduate student from Mumbai University, now in my final year. The topic for our undergraduate project is "Service Oriented Architecture". As a part of this project, we are supposed to build reusable web service components, and then create a demo web application using those services. Please suggest me some ideas for t...
I get some spare time [2/3 hrs daily and weekend ofcourse] which i want to invest on working on some opensource project particularly related to SOA , cloud techs ,,Any suggestions ?? ...
Which is the better Eclipse plugin for developing JAX-WS WebServices? JAX-WS Tools SOA Tools Thanks in advance. ...
My final year project topic is Web-services using SOA. In this we were planning to build individual components like Login, Profile Page, Captcha, etc.. We will then build a demo web application using those components. I have two questions : Do these components(Login, Profile Page, Captcha) qualify as services? Can these components be...
Hi, This may sound like a simple question but as am newbie in Webservies and this is my first time using it and so am asking my doubt. Q: How can I pass objects or complex types using Web Services ? I have created a simple webservice and am passing string and integer types but I am not sure how can I pass objects using webservice and...
We currently have a WCF service that has been setup with its own DataContracts for the enumerations. We then have a mapping layer between the DataContract Enums and the Common Enums available in our business layer. The same thing happens on the client end - a mapping layer between the client Enum and the Data contract Enum We have been ...
OK, so we are using entity framework and wish to expose data from these entities to consumers. This data is pretty common and although initially only consumed by WPF applications it could be consumed by other technologies such as Silverlight, ASP.NET, Office, etc in the future. Typically you would build WCF services that expose a number...
What books/blogs/podcasts etc... discuss patterns and best practices for designing software systems that interact with custom hardware and robotics? I am particularly interested in any books that would discuss strategies for writing a program that has to orchestrate and coordinate actions between several different custom hardware and rob...
I'm studiyng the SOA concept and found out the techniques (should i call it like that?) SOAP and REST (only these ones). I want to know if there are any other techniques (?) that coexist in this context and what do they represent. are they better in something? does many people use them? etc. thanks (: ...
