After a little downtime on the xPages departement I started to do some xPages again ( a few weeks ago ). Today I faced the following problem. We want to transfer data from one app to the other to generate Word documents using a xpage control. The problem is that the call is done in the ‘website’ database and the real logic is stored in the ‘data’ database. The word document is also generated clientside (don’t ask). So I needed to find a way to transfer data from one app to the other.
I first made the obvious error to set a sessionScope and to get that scope at the other application. But since scopes are not inherited (ofcourse..) that didn’t work. The thing I didn’t want was to add multiple url parameters to acccess the other database. So what’s next?
the Remote procedure call! A colleague told me that they are are using RPC’s all over the application currently and maybe that could be a solution. There was only one problem. I didn’t even know that was possible nowadays in xPages. So I first browsed the source to find the current RPC’s and started to create my own.. but all I’ve got was a call that did throw errors all over the place.
To resolve the issue I checked www.notesin9.com to see if there was someone who did a session in the past about RPCs. And yes there is. John Jardin, who is a great speaker by the way, did a vid about RPC’s. Its very basic but it’s just enough for me to get started!
What would xPages be without http://notesin9.com/ and John Jardin…?
