RE: JDBC authentication problem
Hi,
I tried to switch to DataSourceRealm but my problem is here again.
After a while, the authentication is still impossible. Maybe i have missed something about the DataSource in the doc but I'm able to login several times. It's only after about one hour of inactivity.
The network admin looked the firewall config and told me the config was OK ...
So, if you have any idea, you're welcome !
Regards, Luc.

Your Resource configuration is therefore ignored.
The JDBCRealm should really not be used at all. Switch to DataSourceRealm. If you don't like using your application's DataSource for authentication (some folks don't), then create a second DataSource just for authentication.
The DataSourceRealm has some significant advantages, such as being able to use a configurable pool of Connections, instead of a single Connection like JDBCRealm does. This improved performance and allows for re-connections, etc. I think this will fix your immediate problem plus eliminate some other problems down the line (like performance).

None of that should be necessary /at all/. Did you switch-over to
using the DataSourceRealm or not?
JDBCRealm is pretty stupid.

RE: JDBC authentication problem
Posted by Luc DALLEMANE <ld...@alaloop.com>.
Hi,
The keep alive on postgres was already setup, but was not working. However, I finally found a workaround.
I'm using the tomcat connexion pool, but For the authentication, Tomcat is creating its own connexion and does not use the pool (and seems to use the same connexion all along the session).
So I think that's was why it was dropped by the firewall after a while, and when we restarted tomcat, the connexion was recreated and it worked again.
To resolve this problem, we override Tomcat's authenticate method. We made our own open function which uses the postgres driver and is called in the authenticate.
We do not use the getPassword and getRoles function, because they used the Tomcat's "global" connexion.
With this, we are now able to connect to the site even after a long period of inactivity.
Thank you for your help, and maybe this could help someone else.
Regards, Luc.

You might try to enable keepalive on your postgresql connection.
Connection porperties can be specified with the attribute
"connectionProperties" (at least according to
http://commons.apache.org/proper/commons-dbcp/configuration.html) or in
the jdbc url jdbc://...?tcpKeepAlive=true. You can even specify the
timeout for connnecting to your database.

You might try to enable keepalive on your postgresql connection.
Connection porperties can be specified with the attribute
"connectionProperties" (at least according to
http://commons.apache.org/proper/commons-dbcp/configuration.html) or in
the jdbc url jdbc://...?tcpKeepAlive=true. You can even specify the
timeout for connnecting to your database.

Hi,
I'm back again with the problem :)
Firstly, I add the validationQuery and it works and I can see it in postgres logs.
But still not able to login after a while of inactivity....
Now, after 15 min of waiting, I'm getting a socket connexion timeout, but seems logic after such a long period of trying to connect.
Thank you again for your ideas and haven't found a solution.

Do you have validationQuery configured? testOnBorrow, testWhileIdle
do not work without it.

Hi,
Thanks for the reply, I tried to add the options you told me about (testWhileIdle, timeBetweenEvictionRunsMillis, and maxConnLifetimeMillis), but I'm still unable to log after un hour ...
I'm having this problem for 2 weeks and still unable to find a way to go around this problem...
I thought that the firewall dropped my connexions, but no solutions for this problem seems to work.
"(again I assume it is the firewall, that corrupts your connections and I assume you are using a connection pool managed by tomcat)". You were right, I'm using it.
The only thing I haven't test is to not use the pool, but this doesn't seems a really good option for me.
I'm new to Tomcat so I don't know it very well, but this should have worked...
We are thinking of asking a guy from another company (who knows tomcat and network better than I), because nobody have a solution for this in mine.
Thank you for your help !! And if you have another idea... you're welcome again.
Regards, Luc.

First of all, I wouldn't trust the network guys :) The firewall might be
OK, but OK might mean, that it drops connections, when they are idle for
too long.
That said, you have a few options to drive around such a limitation.
You could set "testWhileIdle" to true, so that you generate network
traffic and thus keep open the firewall (again I assume it is the
firewall, that corrupts your connections and I assume you are using a
connection pool managed by tomcat). I believe you have to set
"timeBetweenEvictionRunsMillis" to a postive value, or no idle testing
will be done.
You might try the "maxConnLifetimeMillis" setting, so that old
connections from the pool will not be used.
You might try to size the pool, so that it keeps no idle connections
(but why should I use a pool then?).
Hope this helps

RE: JDBC authentication problem
Posted by Luc DALLEMANE <ld...@alaloop.com>.
Thanks for the reply,
No I haven't got any exceptions, and there is no more logs until I restart tomcat manually.
From the web page, you can see that it keeps loading the page indefinitely... and never tells if the authentication fails or not. (This part works when I restart tomcat).
I'm using the DataSourceRealm provided with Tomcat7.

Are there any exceptions in the log files? Or do you simply get a refused authentication? Are you using Tomcat's built-in authenticator?
Which one?
