Ok. I assumed session ids could be re-used because the SessionClient constructor allows you to pass one in. That explains why my approach isn't working.
I have tried adding a new servlet to the existing BASE web.xml file but I got a strange error that seemed to imply that BASE defines its own ClassLoader. Have you ever seen a problem like this? I'm not clear on the best way to invoke code that uses the native API. Using the webservices API is easy because you just need the relevant jars. Disregarding that, do you have any ideas about how to link directly to an Experiment without getting the 'permission denied' error caused by the wrong project being selected? 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...

No you can't reuse the same ID. It has to be unique for per user session.

From the BASE point of view your web service application is the client. The session ID it uses to set the active project can't be transfered to another client (eg. a web browser). You'll need to add code to the BASE web server application. Eg. add your own servlets, JSP:s, web services, etc. that does the hard work for you using the BASE core API directly. I don't think it can be done by using the current web service API or by calling the JSP scripts. /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 ------------------------------------------------------------------------------ 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
