RE: RES: Objects In Session

2002-07-18 Thread DeVincentiis Giustino 

Hi Craig,

What about using database session state caching (see
http://martinfowler.com/isa/databaseSessionState.html)

Oracle too, in his "Oracle 9iAS Best Practices White Paper", posted last
week on OTN, suggests considering database session state (BP- SESSIONS-1:
PERSIST SESSION STATE IF APPROPRIATE).

RE: Orion and Struts

2001-07-06 Thread DeVincentiis Giustino 

Hello,

I'm using Orion 1.5.2 and Struts 1.0 with MS-Windows 98, I've just unzipped
jakarta-struts-1.0.zip under orion/applications, added the entries in
application.xml and default-web-site.xml and the example works fine.
Let me know if you need some more detail...

I'm using Orion 1.5.1 and Struts_Validator-20010510.jar.

It worked when I changed the load-on-startup value to 1 (or 0).  A value of
2 caused the mentioned error.  What was weird is that if I moved the
 definition for the validator below the strut action servlet
definition in the web.xml file I would get the following error:

It looks different but it's really the same sore of error that struts was
having, it's just not expecting null though.

What version are you using and what did you change to
make it work.  Maybe I can fix it.  Does Orion only
accept '1' as a valid load-on-startup value?

I used the validator with Orion and had a similar behavior, the problem was
in the web.xml.
Check that the  values for the ActionServlet and for the
ValidatorServlet are correct.

Hope this help,

Hi,

I would like to try David Winterfeldt's validator for a new project I'm
working on but I can't seem to get it to work with Orion 1.51.  The default
welcome page comes up and I can see the validator initializing.  I get the
following when trying to go to the registration example page:

Any Ideas?
