I just added the project reference and it worked fine . Thanks for your guidance.
Next time onwords I will post my queries on forum.

Thanks and Regards,

1. Shared Service is actually a bundle which exposes its operation through interface. We need to export this interfaces and domain objects through its MANIFEST.MF file so outside world can see it.

With regard to types (i.e., classes and interfaces), yes you will need to explicitly export the corresponding packages using Export-Package in the bundle's META-INF/MANIFEST.MF file. This concept, however, is identical to the concept of exporting packages introduced in the Shared Libraries WAR. The difference between the Shared Libraries WAR and the Shared Services WAR is that the latter also makes use of the OSGi Service Registry. Please note that the word "service" in this context has no direct correlation to the notion of a "service" in the "service layer" of your application. In OSGi you can publish any object in the Service Registry.

2. To access this service, we need to create a consumer (e.g Web Application) which imports interface and domain objects.

Yes, for the types, that is correct: you would import them via Import-Package statements in your web application's manifest.

The problem is that, Even after exporting from bundle MANIFEST and importing into WAR MANIFEST, classes in web application (Controller) can't see imported classes.

This is expected due to how the STS dm Server Tools work with regard to related projects. Bundle Projects can only see the exported types of other Bundle Projects if:

a) the two projects are configured in the same PAR, or
b) the importing project has configured a "Project Reference" for the exporting project.

For details on this, please see the following forum thread:

http://forum.springframework.org/showthread.php?t=61559

The files module-context.xml and osgi-context.xml in bundle are referenced where and how? or they get automatically detected by dm server and gets registered as OSGI service?

Spring-DM will by convention automatically load any *.xml files found in META-INF/spring as Spring ApplicationContext configuration files. To publish a service in the OSGi Service Registry or to consume such a service, you will need to make use of Spring-DM's <osgi:service> and <osgi:reference> XML namespace elements. You can find more information on these in the Spring-DM reference manual.

For further questions, I recommend you post to the official SpringSource dm Server forum. Doing so will allow more people to provide help, and in addition others will be able to profit from your questions.

Here is small update on my proceedings. I could managed to develope and deploy the follwoing types of web-applications with Spring IDE and dm server.
1. Conventional WAR
2. Spring Enabled WAR.
3. Spring Enabled Shared Library War.
4. Only the bundle for Shared service.

Now I am looking forwad for Shared Service WAR. Please verify my understanding about this concept.
1. Shared Service is actually a bundle which exposes its operation throgh interface. We need to export this interfaces and domain objects through its MANIFEST.MF file so outside world can see it.
2. To access this service, we need to create a consumer (e.g Web Application) which imports interface and domain objects.

The problem is that, Even after exporting from bundle MANIFEST and importing into WAR MANIFEST, classes in web application (Controller) can't see imported classes.
The files module-context.xml and osgi-context.xml in bundle are referenced where and how? or they get automatically detected by dm server and gets registered as OSGI service?

Once the bundle is deployed, Shall I see it somewhere under <>\repository.

Thanks for your time helping me with this problem. The clarification is very neat. I will follow the steps you suggested. Looking forward to give you a good news for successful development and deployemnt of sample application with Spring IDE.

Your response was really quick !Thanks Sam !

Cheers,
Rahul

Great! I'm glad that's working out for you.

Yes, let me try to provide you an overview of the big picture for tooling support: Spring IDE is a set of plug-ins which build upon the Eclipse IDE and add support for Spring applications. The support for working with web applications is provided by the Eclipse WTP project (i.e., the Web Tools Platform). The SpringSource Tool Suite dm Server Tools are Eclipse plug-ins which support working with OSGi bundles, PAR applications, the local bundle repository for the dm Server as well as WTP Server integration for starting and stopping the dm Server and deploying applications to the server.

To create a 'HelloWorld' spring enabled web application, you'll need to use the Web / Dynamic Web Project wizard provided with WTP. I personally recommend naming the "Content Directory" src/main/webapp and the "Java Source Directory" /src/main/java, since these paths will work well with build tools like Maven. After you've created the web project, you can add the Spring project nature to it by right-clicking on the project folder and selecting Spring Tools / Add Spring Project Nature.

The above process will result in a Spring-enabled standard Java EE WAR. If you'd like to convert it to a Shared Libraries WAR or a Shared Services WAR, you should right-click on the project and then select Spring Tools / Add OSGi Bundle Project Nature. This will enable you to use the Bundle Manifest Editor when editing src/main/webapp/META-INF/MANIFEST.MF. Your web project will also now be able to use the manifest classpath container.

To create a Web Module, you should create a new project using the SpringSource dm Server / Bundle Project wizard. You will then need to create the MODULE-INF and META-INF directories in a path which is configured to be on the Eclipse project's classpath. I recommend placing MODULE-INF and META-INF in src/main/resources.

If you are unfamiliar with any of the terms or concepts I mentioned above, I recommend you consult the following resources:

1) Tooling chapter of the dm Server Programmer Guide:
http://static.springsource.com/projects/dm-server/1.0.x/programmer-guide/htmlsingle/programmer-guide.html#tooling

2) Eclipse WTP: http://www.eclipse.org/webtools/

At the moment, there isn't a step-by-step tutorial per se which demonstrates exactly how to create web applications for the dm Server using the STS dm Server Tools, but this is certainly something we are considering adding to the Programmer Guide.

As suggested by you, I studied the sample formstag source code. It was exactly I was looking for.
Then I installed eclipse and updated it with Spring IDE through update manager. I also successfully installed and configured Spring dm server, but Spring IDE doesn't seems tobe very conventional IDE's like Netbeans/IntelliJ Idea. I jsut wanted to create 'HelloWorld' spring enabled web application, but under new project I couldn't find any j2ee web application option. There is option called 'Spring Project' but it didn't do much. I tried many other types of project but I didn't create a basic web application skeletion as I expect IDE to do it. Am I missing something?

I searched the fourums and realised that many people are facing the same problem. Could you please suggest a right way to go about it. If there are any step-by-step tutorial then that would also help.

Thanks for the information and the links. I will surely jump into those sample applications.

I haven't yet made the "hello" demos I used at Spring in Finance eXchange available for download; however, if you visit the SpringSource dm Server community page (see link below), you can download the Form Tags sample application which also walks you through the migration process from a standard Java EE WAR all the way to a Web Module within a PAR.

Links to sample applications: http://www.springframework.org/dmserver

In addition, the migration process is described in detail in chapter 7 of the Programmer Guide. You can read more about that here:

http://static.springsource.com/projects/dm-server/1.0.x/programmer-guide/htmlsingle/programmer-guide.html#formtags-case-study

Hope this helps!
