I've tried to make this link with db4o.

"catlina.out" shows:

Apr 13, 2011 12:00:51 AM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive zkDB_final.war
Apr 13, 2011 12:00:54 AM org.zkoss.zk.ui.http.WebManager <init>:112

here's my sources

and i even added "zk.xml" to "WEB-INF" folder with these contents:

<?xml version="1.0" encoding="UTF-8"?>

<!--

<zk>

Can you post the full log or stacktrace? In your uploaded sources.zip there's no zk.xml contained (only a web.xml), if you don't need a zk.xml, don't drop it into WEB-INF.

Cheers, Maik

thank god you're here.
here's a full log of "catlina.out" from tomcat startup to deploying app.

INFO: Server startup in 23631 ms
Apr 13, 2011 10:36:51 AM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive zkDB_final_.war

I have no idea what "zk.xml" does, but when I remove it. the log file shows:

Apr 13, 2011 10:42:23 AM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive zkDB_final_noZk-xml.war
Apr 13, 2011 10:42:24 AM org.zkoss.zk.ui.http.WebManager <init>:112

Apr 13, 2011 10:42:24 AM org.zkoss.zk.ui.sys.ConfigParser parseConfigXml:158
INFO: Loading system default

and I think there's clue, when I "undeploy" my app, and click "Find leaks" it shows

The following web applications were stopped (reloaded, undeployed), but their
classes from previous runs are still loaded in memory, thus causing a memory
leak (use a profiler to confirm):
/zkDB_final_noZk-xml

and "catlina.out" says:

Apr 13, 2011 10:44:28 AM org.apache.catalina.loader.WebappClassLoader checkThreadLocalMapForLeaks
SEVERE: The web application  created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@6221a86a]) and a value of type [com.db4o.internal.ObjectContainerSession] (value [com.db4o.internal.ObjectContainerSession@fb7f97b]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak. 
Apr 13, 2011 10:44:29 AM org.apache.catalina.startup.HostConfig checkResources
INFO: Undeploying context 

by the way, I'm using "db4o-8.0.184.15484-all-java5.jar"

Sorry, but I don't get your problem... at least I see no errors in the logs. Are you worried about the possible leak?

Cheers, Maik

yes it leaks, and the gui does not work properly.
I just find out that the database file is created and it grows in size after I add an event.

i made everything according to the wiki, except db4o side.

I have a theory, maybe there's a conflict or something between :
> org.zkoss.zk.ui.http.HttpSessionListener
and my "Db4oServletContextListener" servlet which implements "javax.servlet.ServletContextListener",
Cause i tried to make a log text using "ServletContextEvent" but i didn't get anything.

I even removed attributes of <web-app> tag hoping to make any difference. but nothing happend.

oh God, it's more than a week I'm dealing with this issue, and still no result.

heh, this shit happened because I forgot to put all zk libraries there!
:)
now it's working.
I'm just wondering how can I change the status of this topic to "solved".
