Re: How does Tomcat manage sesssions ?
Hello, That solution doesn't pleased me a lot because I want to store the session for all deployed context. How can I do that ? Put the Manager inside the Host, not the Context. I did it in the host but it doesn't seem to work. I don't see any Session stored in my database. Do you know how can I ask Tomcat which Manager he is using ? Thanks for your precious help. Xavier

Depends on the type of crash. It's safe to assume if tomcat can't recover the session, you won't be able to either, so don't waste time writing such code.

Re: How does Tomcat manage sesssions ?
I used that example to write my Manager config. However when the manager
is nested inside the host it doesn't look to work since I don't have any
row in my database.
So I nest the manager in a context as below, and I can see my sessions
in the database.
...
sessionAppCol="app_name"
sessionDataCol="session_data"
sessionIdCol="session_id"
sessionLastAccessedCol="last_access"
sessionMaxInactiveCol="max_inactive"
sessionTable="DBA.tomcat_sessions"
sessionValidCol="valid_session"/>
That solution doesn't pleased me a lot because I want to store the
session for all deployed context. How can I do that ?
I have an other question : should I write something in my servlet to
recover a session for example after a crash or does tomcat do it
automatically ?
Thanks a lot

Hi,
I've read all the server.xml file and there is no marks of the Manager
configuration.
The example was removed a while ago, but you can still see it in older
versions of server.xml by going to the CVS or downloading an old
release:
http://cvs.apache.org/viewcvs.cgi/jakarta-tomcat-catalina/catalina/src/c
onf/server.xml?annotate=1.2 for example has a complete example of a
persistent manager commented out.
I saw in the documentation that "A Manager element MAY be nested inside
a Context component". And In the server.xml there aren't any contexts.
It MAY be nested inside a Context, but doesn't have to be. It can be
inside a Host or an Engine, both of which are more common than having a
Manager inside a Context.
So don't you think that the file to be configured must be
${CATALINA_HOME}\conf\Catalina\localhost\manager.xml ?
No, that's for tomcat's Manager webapp, which is not the same thing as
the session Manager. I realize the names might be confusing.
By the way, don't you have an example ?
We used to ship one with tomcat in server.xml, so see above for
accessing older versions of that file.

You should check out a stock server.xml, then -- it sounds like yours has
been customized and trimmed. Read on:
: I saw in the documentation that "A Manager element MAY be nested inside
: a Context component". And In the server.xml there aren't any contexts.
Either you're using the default settings of autoDeploy and/or
deployOnStartup (so you'll have to create tags yourself), or all
of your webapps use a file named "context.xml" for their per-context
settings (in which case you must update context.xml).
: So don't you think that the file to be configured must be
: ${CATALINA_HOME}\conf\Catalina\localhost\manager.xml ?
No, the "Context" in question refers to the "" element of
server.xml (or context.xml, depending on your setup).
