Hello,

I'm trying to set up authorization and authentication in a RAP project,
using JAAS. I'm having trouble setting the platform up though.

The RAP target platform doesnt include the org.eclipse.equinox.security
plugins. I installed them there manually (hoping it would be alright to do
so), and it solves a few issues, but now Im having access restriction
problems with several classes that Eclipse is resolving in the
javax.security packages. For example, for the Callback class (with import
javax.security.auth.callback.Callback), I get:

Access restriction: The type Callback is not accessible due to restriction
on required library C:\Program Files\Java\jdk1.6.0_07\jre\lib\rt.jar

How should I set everything up to be able to use JAAS in a RAP application?

Thank you :-) Keep up the great work!

Tiago

Try to add the package of this type Callback in the plugin manifest under
"Imported Packages" in the Dependencies Tab of the manifest editor.

I hope it works, i had a simular problem with an other Class.

best regards,

If you add the plugin org.eclipse.equinix.security unter "Required
plugins" and enable option "Reexport this dependency" you get the import
of "javax.security.auth.callback" and many other imports for free.

Wheter this is a good idea may be debatable, but it eases developement
of JAAS login modules.

If the access restriction problem persists check your execution
environment. Maybe it is not sufficient to provide the javax.security
packages (see http://www.eclipsezone.com/eclipse/forums/t97259.html).

p-lex, Roland, thank you for your replies. I experimented with both your
hints, but the javax.security.* packages do not appear as options in the
Imported Packages dialog in either way. I tried adding them manually in
the MANIFEST.MF file, but even though Eclipse did not complain about it, I
still have the same issue.

My execution environment for this plug-in is OSGI/Minimum-1.1. Thank you
for the link Roland, I will investigate.

Still no luck. Apparently OSGI/Minimum-1.1 is not sufficient, and CDC
would be. Is this a valid workaround? Will I be able to deploy the plug-in
onto an equinox container?

TIA,

Tiago

I think so. Depending on the installed JRE your equinox may support even
JavaSE-1.6.

Thank you Roland.

I am getting closer, changing the execution environment to CDC Foundation
(1.1) gave me access to some classes (e.g ILoginContext and
LoginContextFactory in org.eclipse.equinox.security.auth).

I still don't have access to Callback, CallbackHandler or
UnsupportedCallbackException, for example.

I am requiring the plug-ins org.eclipse.equinox.security and
org.eclipse.equinox.security.ui. Are there others that I should require?

I find it interesting that other people have managed to implement this use
case without mentioning these issues, there must be something I have
overlooked.

Thank you,

Tiago

Maybe you should check your project settings, especially the JRE System
Library in the Java Build Path. The Execution Environment specified in
MANIFEST.MF does not influence which JDK eclipse uses for compliling.

In order to use JAAS you need at least JDK 1.4.2.
