Subject RE: check for session
Date Mon, 09 Jun 2003 14:21:42 GMT
Hi Brian,

I mainly develop Web apps that are front ends to Documentum and all the apps
I write are JSP/Servlet based apps and I use the Struts framework to help
build these apps. I use struts to help with the apps flow control and
mapping logic and the custom tags that it provides to help with forms and
display. All Documentum specific code is wrapped in beans that my Action
classes call.

If you require any more specific details please let me know.

Regards

Jim.

Hey Jim, I saw this and it intrigued me. Documentum is a document management
system. I'm curious about how you are using struts with it?? Do you mind
sharing briefly?

Hi Mark,

I use Documentum and struts and had something similar to what you now have
with a Filter determining if a user has a dmSession. I found however that on
a number of occasions when the filter was checking for dmSession it was
returning null (even though I knew it had previously been created) and the
app was recreating the session and saving it. I have now removed the filter
and written a custom tag that checks for the existence of the dmSession and
if it does not exist creates it, if there is a problem creating the
dmSession the user is redirected to an error page.

Regards

Jim.

Thanks, worked like a charm, never used that before, very nice.  The
filtering mechanism though makes me wish I'd set up the app directory
structure differently but you know hindsight 20/20 and all that...
