Hi All,
I am confused.
I understand that WCF is about unifying technologies...
what i do not uderstand is when it is about inter appplication communication, what is it that WCF provides that webs service + WSE 3.0 does not provide?
Remoting is primarily talked about while splitting business and presenation of one application ...
and not talked about when it is application to application communication.
I do not understand how WCF help implement remoting. Is it that WCF supports inter application communication based on TCP protocol and hence we say it "unifies remoting". In remoting we have to
register a type after registering a channel. In WCF do we not want a type like abcd.rem at the
server and client ends?

Hi,
to make it short: WCF contains the options of web services but also more. WCF is the unification of all (microsoft) distributed technologies . It is not tied to use the TCP protocol. E.g. you can use the MSMQ for transport or a self-defined way.
I suggest reading this article:
http://msdn.microsoft.com/en-us/library/ms731082.aspx[^]
If you think of WCF as a kind of protocol stack (like ISO/OSI), then there is the transport layer (MSMQ, TCP/IP or carrier pigeons), above would be a security layer, followed the layer defining the data that should be send and so on.
Hope this helps you a bit.
Regards

Hi,
Component oriented is about sharing class, registering types and invoking method using object reference.
Service oriented architecture exposes methods using contracts and schemas and policies.
But what I do not understand when I read that SOA helps in improving scalability.
Just by changing type from component to Service oriented, how is scalability improved.
Even in component oriented architecture, i can leverage resource management services offered by COM+ to
get hold of object pooling and JIT activation, which helps in handling more requests.

Have you ever tried to use COM+ services between different locations across a WAN?

Hi,
Probably I am trying to understand remoting and web service before properly understanding Component Based
Architecture and Service Oritented Architecture.
gray, could you help me with a link where I can understand the difference.
If you were to tell someone why there was a need to evolve and create Component based architecture
and then why there was a need to evolve and create service oriented architecture what would it be?

If you have never implemented any of these things it is difficult to explain to you in terms that you would understand. There is no way you are going to get a good in depth understanding of the concepts from reading forums posts. A search for SOA on Amazon comes back with over 1500 books. Try readng some of those.
It sounds like you are taking an online course and just giving us your test questions.

Gray,
i have read the book meant for MCTS exam ...
(book name is .NET Framework 2.0 distributed Application Developement)
... i am not preparing for the exam.
Although this book helped me implement simple programs on .Net Remoting,
web service, MSMQ, serviced components and me aware of options in
distributed technology, it does not talk about reasons on why we
needed methodologies like CBSE and SOA and why we needed new technologies.
That aroused my curiousness ... browsing net is not helping me understand my questions.
... I am planning to become a trainer.
Is there a specific book you can recommend. Will appreciate that.

NetQuestions

Many people would be upset to learn that the person training them in something had no practical experience with the topic of the training.
Start with the Wikipedia article on SOA, plus all of the items in the external links and references sections of that article. If after all of that you can't answer the series of questions you have asked here regarding SOA methodlogy then you may need to find a different topic to train.

Hi,
I am developing the webpage using jsp. There is a table in the page in which rows are added dynamically. each row contains multiple textboxes in different column. The first column's textbox requires the aucomplete facility.
The scenario is rows are added dynamically. There is only one row when page loads. I downloaded the code from this site which is working perfactly fine for the one textbox. if I add the same functionality to another textbox (created dynamically) it fails.
Can you please help me in resolving this issue?
Thanks,
Hemant

Hi,
One of the advantages of distributed architecture is scalability and by scalability I understand it is scale-out and
not scale-in.
We are looking at adding more computers.
Now by scaling it should mean that there is a need to increase the processing power, and this is achived
by adding more computers and I believe more computers are being added at the server.
But isn't this the same as load balancing, are we not offloading work???
Is scale-out meaning loading balancing?

With scalability we usually mean that something can be extended, to serve "more". With load-balancing we usually mean dividing the workload over what's available.  I are Troll

hi eddy, so here we are adding more and more systems so that the same nature of requests can be handled simultaneously across a group of servers.
... and load balancing is when one request is being split on multile machines.
please correct me if I am wrong.

It's usually not the request that is split, but a number of requests that get balanced between computers that can handle them. The most cited example would be a webserver, where any server might fetch the page. If the systems handle the same requests by dividing the work, then I'd say that it probably scales well.
Out of curiousity, what kind of work does the farm do?I are Troll

Right clicking on a web project presents the option to publish a web site to a directory, ftp or other destination.
Does anyone know if that publish action can be automated so that I can trigger a build/publish/deployment application (I have to publish to a directory and then package that to deploy on the server).
Does anyone have an MSBuild project that publishes their project to a directory automatically?
Any thoughts greatly appreciated.

Of course.
Right click your solution
Select add new project
go to Other Project Types and select Web Setup project
Once the project is added to the solution, right click on it
select add output
In the dialog, select the web application you want to publish
Select all the items appear below the project except the source code
click ok
build the setup project
Now, you have itforeach(Minute m in MyLife)
myExperience++;

I may not understand this completely, but I believe this creates an executable that I would run on a web server. I don't have shell access on my server.
What I'm really looking for is something that would automate publishing to a directory. I have my own tools that will wrap that up and handling updating my web server.
Is there an MS Build action that will do this?

Exactly.
hb52134214 wrote: I don't have shell access on my server.
No need for shell at all
Run that exe on your server and it will do most of the work on behalf of you
After installation completes, go to IIS, and adjust settings like authentication mode, default document, and application pool

Try being a little bit more specific. Do you mean java portlets? jQuery portlets? Do you mean google gadgets? Windows sidebar gadgets?
Do you have the source for the thing you want to convert? If not, then no you can't convert it.

First of all thanks Gray for your reply,
yes,I mean java portlets convert to google gadgets.Some portlets i have source,but for some i only have url only.I don't want to rewrite them as gadgets.Again thanks Gray

Hello
I'm sorr to re-post here but maybe it is a better place than C#
I'm a newbie with WebService creation
For now, everyhing works fine, my Service run on a server and my Client can use it
Now I need to add autentification to the service ...
How can I do that simply on the server site ?
It does'nt need to be very secure, I just want to understand how to do it
I have an example of another service that I'm using as a client
I just have to assign a NetworkCredential to the service's client instance to be able to use it
How can I achieve that on the server side
Thanks a lot for any help
