Hi,
I'm trying to register a directory which I intend to write files to at
runtime, making them available to users via a URL. So far I've specified
the directory as a resource in my plugin.xml:
<extension
point="org.eclipse.equinox.http.registry.resources">
<resource
alias="/project-bin"
base-name="/project-bin">
</resource>
</extension>
And at runtime I've tried calling
RWT.getResourceManager().register("project-bin/testfile"); (testfile is
just a file I've placed there). I get the exception:
org.eclipse.rwt.internal.resources.ResourceRegistrationExcep tion: Failed
to register resource 'project-bin/test'.
Could anyone tell me what I've done wrong and also how to access this
directory in my Java code so I write to it?
Thanks,
Mike

Hi,
just one thing I forgot. The resource directory you've mapped using the
resources extension point resides in your local project and - think
about deployment time on a linux-machine for example - therefore you
should not try to write to this directory at runtime.

Hi,
where exactly did you place the testfile? In your case the file is
expected on the classpath of the current context classloader of the
ResourceManager, so probably your file isn't found. The usage is s.th.
Like this:
ClassLoader loader = Activator.class.getClassLoader();
IResourceManager manager = ResourceManager.getInstance();
ClassLoader bufferedLoader = manager.getContextLoader();
manager.setContextLoader( loader );
try {
String path = "path/to/image.jpg";
manager.register( path, loader, getResourceAsStream( path );
} finally {
manager.setContextLoader( bufferedLoader );
}
Ciao
Frank

Thanks, the registering code works but with regards to writing to
resource directories, that's what I'm trying to achieve - being able to
generate files at runtime so that my custom widgets can download them
via URLs. What would you suggest is the best way of doing this? Maybe
there's a much simpler approach?

Hi,
there are several possibilities I guess and it depends on the exact case
and maybe your taste which one you use. I case that you generate files
at runtime you can use the ResourceManager approach I mentioned in a
previous post (sorry for the typo in the register paramenter list). This
approach register the files automatically to the download directory
root. Another way could be to use the bundle's statelocation to store
the files and use a servlet or a service-handler for delivery. It's not
easy from my point a view to propose the best way, since I don't know
much about your usecase, e.g. are those resources only relevant for one
user-session or are they shared for all users etc.
Ciao
Frank
