Mmmhhhhh, not sure of that. i can
deploy and run successfully the application on the tomcat version if i
comment out the sitemesh filter mapping in web.xml even if i get the
filenotfoundexception during shutdown.

Paolo,
I was able to reproduce this problem with your test app. I also found
out that any EAR deployed at the root context (using tomcat) will have
the same problem. It is not hibernate/spring/sitemesh specific. It may
be a bug in Geronimo. The problem occurs because when the server is
shut down, the sessions are not being saved properly. You can try to
get this error with the following:
1. deploy an EAR at the root context (in tomcat)
2. stop the server (you should get a FileNotFoundException) <-- this
is the cause of the problem
3. start the server
4. try to view the web app at the root context (there should be
problems viewing it)
As you mentioned, this only happens with EARs, the WAR equivalent works
fine.
I will keep digging.

p.s. if you want your app to work on tomcat, you have to redeploy the
app on the server. When you visit the website it should be working. But
like I said, if you stop the server, there will be a
FileNotFoundException.

Hi
Paolo,
Which DB are you using? I could not get this to work on the derby db
that comes with Geronimo because it doesn't support some keywords (e.g.
AUTO_INCREMENT), but when I used MySQL everything works fine (with or
without the commenting of the filters in the web.xml and on both jetty
and tomcat containers).

Hi Kevan,
you can find the deployable ear here:
http://www.mediafire.com/?8mdty2cu0mm
and just the webapp with sources included here:
http://www.mediafire.com/?d6ml6l1hgj4
in order to deploy the app, you need a connection pools named TestDS,
pointing to an existing db, nothing more (a table named test will be
automatically created in that db).
deploy and just browse to http://localhost:8080/index.htm
on the tomcat
version to get the problem
about the Viet links, those links are jmx related, and i cannot solve
the problem just
setting MBeanExporter's
"exposeManagedResourceClassLoader" property to "true"
moreover, seeing in which conditions it happens (for example point 4)
it looks more a geronimo problem, being related to the web context.

Hi
Kevan, Viet
i prepared a basic spring/hibernate application using jta on geronimo.
it works.
then i tried to add all the components i am using in my "bad"
application, one by one, and, finally, i found it:
it was very difficult because the problem happens under an incredible
particular set of conditions in AND:
1) the most important: sitemesh is used to render pages
2) you deploy an ear (deploying just the war, it works always)
3) you use the tomcat version of geronimo (with the jetty version, it
works always; i discovered it at the end of all tests !!)
4) the web app in the ear has the root context (in the sub contexts, it
works always)
just commenting the sitemesh filter mapping in web.xml,
everything
works. if i apply sitemesh filter, i get
org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is java.lang.IllegalArgumentException: interface org.hibernate.jdbc.ConnectionWrapper
is not visible from class loader
i can make it available for everybody
if needed.
otherwise, if you prefer, just try to modify Viet app. in this way:
1) add "sitemesh-2.3.jar" to WEB-INF/lib
2) add "decorators.xml" to WEB-INF
<decorators defaultdir="/WEB-INF/decorators">
<decorator name="default" page="default.jsp">
<pattern>/*</pattern>
</decorator>
</decorators>
3) add "decorators" folder to WEB-INF
4) add default.jsp to decorators folder

5) add sitemesh filter to web.xml
<filter>
<filter-name>sitemesh</filter-name>
<filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class>
<init-param>
<param-name>debug.pagewriter</param-name>
<param-value>false</param-value>
</init-param>
</filter>
....
<filter-mapping>
<filter-name>sitemesh</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
6) execute your web controller which users jta: you should get an
exception
Paolo -- wow! Thanks a bunch for tracking down this
detail. This
is terrific.
Did you try either of the suggestions that Viet proposed?

Strange. I had no problem with my test ear... If you could
make
your test app available, that would be great.
