[2.1] add a project to multiuser workspace [message #1060614]

Hello,

I have started to create an emf editor running on RAP 2.1. I've created an emf model, generated an rap editor on top of the model and made some modifications to this editor yet. What I want to do now is to provide a project with xml files to all instances of this editor. At the moment I'm able to give my 'new model file wizard' a file uri to a local xml file and create a model instance with my editor starting afterwards. I can modify this model file and write it back as a xml file to my local machine. But I'd like to keep these xml files in the RAP workspace. How can I do so? Is it possible to add a java project to the shared workspace? Is there a workspace at all in an RAP application? Couldn't find any information about this yet.

Greetings,
Sascha

And I guess to load this project I will need the org.eclipse.core.resources package? Is this package able to work with RAP?

Ok, I've managed to copy all the missing dependencies from Eclipse to my RAP plugin and tried to load the project by:

IWorkspace workspace = ResourcesPlugin.getWorkspace();
IWorkspaceRoot root = workspace.getRoot();
IProject project  = root.getProject("ConfigFiles");

But now I get the following error:

java.lang.IllegalStateException: Workspace is closed.

Any ideas on this? I've copied the ConfigFiles project to the following path:

org.eclipse.rap.ui.launch/<projectname>/

Ok, next attempt but same problem. I guess I need to startup the ResourcesPlugin via

ResourcesPlugin.getPlugin().start(FrameworkUtil.getBundle(this.getClass()).getBundleContext());

But the ResourcesPlugin.getPlugin() returns NULL.

Hi Sascha,

as you've found out, the resources plug-in is not available for RAP.
Implementing it would require to setup different workspaces for every
user. However, there's an instance area (that's the place where the
resource plug-in would create the workspace). This instance area is
shared among all users.

You can set the workspace using the -data parameter, and obtain its
location from the system property "osgi.instance.area".

Does that help?

Hi Ralf,

thanks for your answer. But can I ask you how to load an IProject from this location? I've set the parameter and successfully read out the osgi parameter in my RAP application. But can I use the IWorkspace interface with the newly given data location or is there another way to read a project from this location?

Greetings,
Sascha

you can't. There is no resources plug-in for RAP, hence no IProject or
IWorkspace. If you need these interfaces for your project, then this
would require a RAP implementation of the resources plug-in.

Ok, thanks a lot. I've figured it out. Smile
