AW: [geclipse-dev] Token creation

["Stuempert, Mathias IWR" <mathias.stuempert@xxxxxxxxxx>]

Hi Romain,

In principle it is very simple to create a token with g-Eclipse:

IAuthenticationTokenDescription desc = new VomsProxyDescription();
AuthTokenRequest request = new AuthTokenRequest( desc, "This is me", "I need a VOMS proxy" );
IAuthenticationToken token = AbstractAuthTokenProvider.staticRequestToken( request );

Assuming you are not in headless mode and the UI is available this will open the token wizard in VOMS mode asking the user to specify a certificate, key and passphrase. You could also encode default VO, certificate and key in your VomsProxyDescription:

IAuthenticationTokenDescription desc = new VomsProxyDescription(
  new IVirtualOrganization[] { myvo },
  mycert,
  mykey
);

If you would like to directly create a VOMS proxy without UI interaction (i.e. you already know your VO, certificate and key) you should do something like this:

VomsProxyDescription desc = VomsProxyDescription(
  new IVirtualOrganization[] { myvo },
  mycert,
  mykey
);
AuthenticationTokenManager manager = AuthenticationTokenManager.getManager();
VomsProxy proxy = ( VomsProxy ) manager.createToken( desc );

If you create the token with the manager it will cache this token for you and manage the tokens lifecycle. The token can afterwards be retrieved with

VomsProxy proxy = ( VomsProxy ) manager.findToken( desc );

If you do not need the token management capabilities of g-Eclipse you could simply do something like:

VomsProxyDescription desc = VomsProxyDescription(
  new IVirtualOrganization[] { myvo },
  mycert,
  mykey
);
VomsProxy proxy = ( VomsProxy ) desc.createToken();

Depending on the method you are chosing you may have to validate and to activate your token after the creation:

if ( ! proxy.isValid() ) {
  proxy.validate( null );
}
if ( ! proxy.isActive() ) {
  proxy.setActive( true, null );
}

You can find a lot of useful code examples in the following classes:

eu.geclipse.core.auth.CoreAuthTokenProvider
eu.geclipse.ui.UIAuthTokenProvider

Hope that helps,

Mathias

Betreff: [geclipse-dev] Token creation

Hi all,

I'd like to write a code creating a token from a voms certificate using 
geclipse classes. I think I should use the AuthenticationTokenManager 
but I cannot get through with it. May you point at me source codes that 
will help me?

Thanks,
Rom
