That's a bit tricky, since the PageProvider interface does not support
sending any information about the request through the interface
itself. From the Provider's point of view, the engine is a complete
black hole.
You *can* however do some trickery by creating a PageFilter or a
ServletFilter which sits in front of every request, and stores the
credentials inside a singleton, which contains a ThreadLocal to store
the credentials, which can then be fetched by the Provider.
E.g.
class MyFilter implements Filter
{
public static ThreadLocal<MyCredentials> c_credentials = new
ThreadLocal<MyCredentials>();
public void doFilter( ServletRequest request, ServletResponse
response, FilterChain chain )
{
m_engine.getAuthenticationManager().login( httpRequest );
WikiSession wikiSession =
SessionMonitor.getInstance( m_engine ).find( httpRequest.getSession() );
c_credentials.set( new
MyCredentials(wikiSession.getLoginPrincipal()) );
chain.doFilter( httpRequest, response );
}
}
...
class MyProvider implements WikiPageProvider
{
public boolean pageExists( String page )
{
MyCredentials c = MyFilter.c_credentials.get();
...
}
}
Or something to that effect. A bit complicated, but would work. The
ThreadLocal part is important. You could also store the entire
WikiSession in there, if you wanted to, but then you want to be
careful as to make sure that it gets collected by setting it to null
after using it. WikiSessions can be big.

Hi developers,
I thought my problem was solved with JSPWiki 2.8.3 but unfortunately
is isn't.
What I like to do is to use an own WikiPageProvider which gets the
Wiki pages from an external repository. The access to this
repository is restricted so I need a login handle or at least a user/
password information.
Beginning with release 2.8.3 there is a WikiEngineCallback available
in the AbstractLoginModule.login(). Now I can do a custom login, get
a login handle from the given user/password and store it in the Wiki
engine object. Later on the page provider can pick that handle from
the Wiki engine and use it to get the Wiki pages from the repository.
Now my problem is that the Wiki engine is not bound to a session so
if someone logs in then his login handle is globally visible.
Is there a way to solve my problem?
Thanks for your help!
Best regards,
André
