Ok, let's say we have a context that doesn't timeout... we could do
as you say and get the dir context in the setContext method. But that
would mean that for every different user I want to use in my
application, there will be a different connection to LDAP. This lead us
to connection pooling.
If connections to LDAP timeout, is there any way to detect it? Or the
only way is caching an exception when trying to make an operation on
that connection? (I'm just guessing here, I don't know deeply JNDI and
the LDAP provider) If we have the later, that makes difficult to have a
connection pool, as we could serve connections that have timed out,
unless you have some tricky mechanism to refresh older connections in
your pool, as you suggest in your mail. Doing this could imply thread
usage unless we refresh connections under client requests, that could
cause what we are trying to avoid. And thread usage is forbidden in J2EE...
By the way, I'm using Active Directory, and it does time out... a
client requirement :(
What do you think?
Regards
Jose
