Deploying single sourced RAP/SWT application [message #1138481]

We are single sourcing our application for both RAP and SWT versions of GUI. For instance, in our UI bundles we have optional dependencies on org.eclipse.ui and org.eclipse.rap.ui so that depending on runtime target used the application would make use of either RAP or SWT implementation of GUI widgets.

Now, the RAP and SWT bundles can't co-exist in the same runtime target (it would lead to clashes of package and class names and other inconsistencies). Therefore in my development environment I am using OSGI framework launcher where I hand picked RAP set of bundles or SWT set of target bundles.

However, for efficient deployment of our application I'm looking for guidance here. What is the recommendation for deploying single sourced applications that are expected to function as either SWT or RAP applications and given that RAP and SWT targets cannot coexist in the same runtime space.

Is there a way to make this work at deployment time with all target bundles in the same folder but only their subset would get loaded at runtime depending on UI version picked?

Should we handcraft Eclipse configuration in advance and have SWT version of our application use one configuration and RAP version would use another? This seems like a manual and fragile approach.

Thank you in advance

Hi Barys,
some tutorials/recommendations for RAP/RCP single-sourcing are available

Thank you Ivan for the link. It provides some very valuable tips and hints.

I'm still looking for a clear picture of how the dual application (RAP + SWT) should be deployed to customer's machine. Is it possible to keep both SWT and RAP bundles in the same folder 'eclipse/plugins'? Should we create two separate launch configurations with their own 'configuration' folders that would define which subset of Eclipse bundles should be loaded for each eclipse application? If this is the answer, how should these 'configuration' folders be maintained (e.g. should we maintain contents inside platforms.xml file manually or there is a more reliable way to do it)?

Thank you
