Re: [dsdp-ercp-dev] Workbench references org.eclipse.swt.dnd.Transfer

[Danail Nachev <d_nachev@xxxxxxxxxx>]

I did the following:

1) downloaded the 1.0.2 runtime for S80 device
2) installed it
3) retrieved back the org.eclipse.ercp.swt.jar bundle
4) examined its manifest and found out that the org.eclipse.swt.dnd is
not part of its Export-Package header.

As long as I remember the eSWT for S80 is installed separately, so is
there a chance that the package is there (in the bootclasspath), but it
is not added to the org.eclipse.ercp.swt bundle.

There is absolutely no problem with this. This comes from the default
behaviour of the Equinox, where it delegates everything to the
bootclasspath first, so there is no chance that someone will have problems.

However, I think it is good if we change the org.eclipse.ercp.swt bundle
to export all available eSWT packages. It won't do any good but it won't
do any bad too. It will just clarify which packages are available for
eRCP applications.

The best thing which we can do is deploy eSWT bundle as fragment to the
system.bundle. This way, the packages will be exported properly, the
classes will be available to the bundle and there won't be any need for
boot delegation. This is the recommended way to export packages in the
bootclasspath. However, this way the eSWT cannot be imported via
Require-Bundle.

I wonder what is the limitation which force the deployment of eSWT in
the bootclasspath?
