[Resin-interest] cascade persist with Amber
Hi list
I'm playing around a bit with Amber and can't seem to get cascading
persist to work. The attached code runs fine but doesn't persist the
competences, only the search.
Have I misunderstood something?
Thanks in advance,
Torkil

[Resin-interest] snapshot (2008-03-31)
A new snapshot is available. It's primarily bug fixes. There is a new, important reliability capability in Resin-Pro, based on monitoring the CPU load. The stat-service in management can set different CPU load triggers, for example: logging the CPU load logging a thread dump if the load is high or even exiting Resin on very high loads The tag docs are at http://caucho.com/resin/doc/resin-tags.xtp.

[Resin-interest] Open SSL and multiple sites
We have multiple sites running on Linux ... entirely through resin 3 +. We need to implement SSL on several but not all of the sites. The documentation I can find seems to be for single sites on a single machine. Is there documentation for multiple sites on the same machine running on resin using Open SSL ... ?? ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
[Resin-interest] admin log already exists after server restart
Hi Scott,
These lines in resin.conf will cause thie problem:
management path=${resin.root}/admin
user name=admin password=password disable=true/
resin:if test=${resin.professional}
deploy-service enable=true/
jmx-service enable=true/
log-service enable=true/
xa-log-service enable=true/
/resin:if
/management
The first time I start the server, everything works fine.
But If I restart it, I get an error:
C:\resin-pro-3.1\conf\resin.conf:21: java.sql.SQLException: Table 'log_'
already
exists. CREATE can not override an existing table.
19: - Remote management requires at least one enabled admin user.
20: --
21: management path=${resin.root}/admin
22: user name=admin password=password disable=true/
23:
If I manually delete the two logs files in ${resin.root}/admin/log and start
resin again, it started with no error.
I think this problem is a bit like http://bugs.caucho.com/view.php?id=2065 .
The s080321 and s080331 snapshot both produce this problem.

Re: [Resin-interest] Session cookie in a different path than /
Is there a way to set the session cookie (jsessionid) in a different path than the root (/)? I would like Resin sending the browser something like: Set-Cookie: JSESSIONID=a8_9DJBlfsEf; path=/test but Resin always setÑ Set-Cookie: JSESSIONID=a8_9DJBlfsEf; path=/ We are working in a application served by different AppServer throught a proxy. All the requests are in the same domain but our proxy redirect the request to the correct AppServer discriminating by context-path. So we need the session cookie to be set also per context-path not in root, because if not the AppServer will overwrite the other AppServer cookies. If the concern is that you have app servers other than Resin, you can tell Resin to use a cookie name other than JSESSIONID http://caucho.com/resin/doc/cluster-tags.xtp#session-cookie If you have multiple instances of Resin, they will not have a problem using the cookie value that was established by other servers, as long as reuse-session-id is true (which is the default). reuse-session-id is documented here: http://caucho.com/resin/doc/session-tags.xtp -- Sam ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
