Multiplatform Web Start export for RCP app [message #435317]

Hi,

I'm exporting my RCP application as a Java Web Start/JNLP site. I also
have the RCP Delta Pack installed to allow multiplatform exports.

However, the export wizard builds completely separate folders for each
selected platform. For example if I choose to export to both Windows and
Mac, I get two separate copies of my application under a win32.win32.x86
directory and under a macosx.carbon.ppc directory. On the other hand the
only difference I can see between these two copies is the
platform-speficic SWT fragment jar.

I don't really want to put up separate Web Start URLs for each platform.
Can I simply copy the Mac SWT jar into the win32 export directory to allow
that JNLP app to launch on both platforms? Unfortunately I don't have
anything other than windows boxes to test on.

Thanks,
Neil Bartlett

I want to do the same.

I would say so as it is possible to declare resources on a per platform
basis within the jnlp file.

Would you mind telling me your rcp setup? Is it feature or plugin based?
Do you use manifest or plugin.xml files? Is only one plugin present oder
several plugins which are declared in the osgi.bundles property? Do you
have a external build process or the gui based export?

I am lost in the maze now and get strange errors when I export my rcp or
try to run plugins not defined within the main application plugin.

PS
I am on linux and able to click a webstart link and post the logs.

There is no capability to export for multiple platforms at once. However
if you export in the same folder multiple times you will get the desired
effect.
At runtime the filtering will be done by the filters that are part of
jnlp file. The filters are generated according to the platform
information associated with each plugin in the feature.xml.

For example:
if you export the org.eclipse.rcp feature for win32, you will get a
folder with all the non platform specific plugins and swt.win32.
if you export a second time for linux gtk, you will get a folder with
all the non platform specific plugins and swt.linux.gtk.

Yes, you can deploy the same WebStart location for both products. Just ensure that both the versions of SWT are installed in the same place and the appropriate one will be picked.
