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 INFO: Starting ZK 5.0.6 CE (build: 2011022418) Apr 13, 2011 12:00:54 AM org.zkoss.zk.ui.sys.ConfigParser parseConfigXml:158 INFO: Loading system default Apr 13, 2011 12:00:54 AM org.zkoss.zk.ui.sys.ConfigParser parse:273 INFO: Parsing jndi:/localhost/zkDB_final/WEB-INF/zk.xml
here's my sources
and i even added "zk.xml" to "WEB-INF" folder with these contents:
<?xml version="1.0" encoding="UTF-8"?> <!-- Created by ZK Studio --> <zk> </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 Apr 13, 2011 10:36:53 AM org.zkoss.zk.ui.http.WebManager <init>:112 INFO: Starting ZK 5.0.6 CE (build: 2011022418) Apr 13, 2011 10:36:54 AM org.zkoss.zk.ui.sys.ConfigParser parseConfigXml:158 INFO: Loading system default Apr 13, 2011 10:36:54 AM org.zkoss.zk.ui.sys.ConfigParser parse:273 INFO: Parsing jndi:/localhost/zkDB_final_/WEB-INF/zk.xml
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 INFO: Starting ZK 5.0.6 CE (build: 2011022418) 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.
you guys here's my final war file inside this zip file. size=4.8 mb.
sources and libraries included, even buid.xml is included.

now the application does not run! it shows a complicated error page:

catlina.out looks ok :
Apr 13, 2011 10:49:44 PM org.apache.catalina.startup.Catalina start INFO: Server startup in 7294 ms Apr 13, 2011 10:50:53 PM org.apache.catalina.startup.HostConfig deployWAR INFO: Deploying web application archive zkDB_final-gong.war
but localhost.2011-01-27.log is full of details:
http://pastebin.com/Sd5d0C7C
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".
