Not in this context, but Tomcat does. http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html > Have you ever seen a problem like this?

You can't link directly. You need to set the active project first. To do this you need code that is living in the BASE web application that calls SessionControl.setActiveProject(). You could for example create a servlet that takes four parameters: login, password, project ID and experiment ID. Then something rougly like this: // Create a new session and login SessionControl sc = Application.newSessionControl(....); sc.login(login, password, ....); // Then, active the project Project p = Project.getById(...); sc.setActiveProject(p); // redirect to the experiment page response.sendRedirect(....); > I'm assuming it would actually > be possible to write a servlet that automatically authenticates the > user, sets the active project, then redirects to the experiment? I'm > not sure of the best approach... Neither am I... you'll need to fill in a lot of blanks in the "code" above. The example above creates a new session every time. If you need something different, you'll probably need to mange the session id's in your own application and add that as a parameter to the servlet as well. The servlet should then first check for an existing session before creating a new one: Application.getSessionControl(...); /Nicklas ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ basedb-devel mailing list basedb-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/basedb-devel
