Re: [basedb-devel] Setting active project via API
A long time ago now, I remember having problems with experiments/projects. You would think it would be enough to add Everyone group to the project and then it would be visible, but as others have pointed out, the project has to be active before the expt is visible. We decided to just share all project items to Everyone and be done with it(*). You might get the granularity you need by sharing to groups instead.

Re: [basedb-devel] Setting active project via API
I have added a servlet to the BASE webapp that does the following: SessionControl sc = Application.newSessionControl(net.sf.basedb.clients.web, request.getRemoteAddr(), null); sc.login(username, password, null, false); DbControl dc = sc.newDbControl(); sc.setActiveProject(Project.getById(dc, projectId)); dc.close(); response.sendRedirect(String.format(/base/views/experiments/index.jsp?ID=%scmd=ViewItemitem_id=%s, sc.getId(), experimentId)); Haven't done much testing, but seems to work so far. I'm passing in the project ID because an experiment can be shared with more than one project (as previously discussed). I could make more of an effort to avoid creating unnecessary sessions, but not sure if this is worthwhile. Presumably I could avoid passing the user's password by putting the root password in the servlet and impersonating the real user. Thanks for all the help, Mark.

Re: [basedb-devel] Setting active project via API
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...

I know this issue has come up on the mailing list a couple of times, but I'm not sure what the solution is. As I said, I'm linking directly to Experiments in BASE from my Flex application. I'm doing this by doing an HTTP POST to /login.jsp with a redirect to views/experiments/index.jsp?cmd=ViewItemitem_id=...ID=... This works fine but there are a couple of problems. The first is that I call /login.jsp every time I link to an experiment. I'm using the same ID every time to avoid creating a new session. Is this the correct thing to do? No you can't reuse the same ID. It has to be unique for per user session. Strange things will happen if there are multiple sessions using the same ID. The second problem is this issue with the active project. What is the correct way to ensure that the link works i.e. avoiding linking to an Experiment that isn't shared with the 'active' project? I have tried the following: 1. Generate a session ID 2. Use the webservices API to set the active project for this sessionID 3. Post to /login.jsp using this sessionID But this doesn't seem to work. Is there a way to link directly to an Experiment, ignoring whatever Project is currently active? Any help would be gratefully received. No this will not work. 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

There doesn’t seem to be an ExperimentInfo.getProject() method. There is no such method since an experiment can belong to more than one project. The web service API has very limited functionality. The functionality that currently exists was implemented to support some specific use cases (mainly related to downloading data files) for a project that we participated in. Using the regular BASE API you can find the projects by putting the experiment in a collection and then using a multi-permissions object: CollectionExperiment experiments = ... MultiPermissions mp = new MultiPermissions(experiments); ItemQueryProject q = mp.getProjects(); ListProject project = q.list(dc); The code is a bit awkward, but for some reason the obvious approach, Experiment.getProjectKey().getProjects(), is missing. /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
