Hi all,
I'm trying to write a custom user group/role details service for
Geoserver. I've created my own implementations of the usergroup and role
services, which appear ok in the web interface, but I have a problem of
accessing the list of users and roles.
I get a lazy load exception when accessing referenced entities of my
user entities, because presumably the db session used has been closed
before the view is generated. The easiest solution appears to be to use
the "Open session in view" filter which would normally go in web.xml.
As this is supposed to be an add-on module, it would more approproately
go in the jar file, so I would be including META-INF/web-fragment.xml.
The problem is that Gepserver is using the 2.3 web application spec, and
web-fragment support is only in 3.0.
Could anyone suggest a solution to this?
Thanks,
Mark

GeoServer won’t be based on Servet 3.0 for some time, we try to keep
back a version in order to allow conservative deploys to still function.
Happily enough though we have an extension point in Spring that allows
a Servlet filter to be plugged in, you just have to make it implement
the org.geoserver.filters.GeoServerFilter interface and declare it as
a bean in the Spring application context (applicationContext.xml file,
in the root of your module classpath) and it will be picked up on startup
(well, provided your GeoServer is recent enough, it has been around
for more than one year now)
Cheers

There is an example of doing exactly this in the monitoring module which uses hibernate.

I’ve just sent a pull request to add OpenEntityManagerInViewFilter, which should do the same as OpenSessionInViewFilter but for JPA. Hope it’s a sensible thing to do… Cheers, Mark
