I am using hibernate 3 and mysql 5.1.When I am connecting it to database after it crosses the wait_timeout of mysql I am unable to create the new session.It gave me the following exception.

I know the exception is due to the stale SessionFactory object and it is not able to open Session.When I am restarting the application it runs fine till it does not crosses
wait_timeout time.I referred this link :http://www.codefin.net/2007/05/hibernate-and-mysql-connection-timeouts.html and done the same procedure.I used the C3P0 for the connection pooling but came out with no success.
I am using these properties in my hibernate.cfg.xml file:
<property name="connection_provider_class">
org.hibernate.connection.C3P0ConnectionProvider
</property>
<property name="c3p0.minPoolSize">5</property>
<property name="hibernate.c3p0.idle_test_period">20</property>
<property name="hibernate.c3p0.timeout">15</property>
My mysql wait_timeout is 30 seconds.
One alternative is to create new SessionFactory object every time I need Session but this has performance issues and dont want to follow it.
Please tell me is anything else is required in my configuration or where I am going wrong.
Thanks,
Amandeep

When the HTTP request execute the select SQL to query some data, the exception occurs. I am using the dynamic datasource, Spring 3.2.4, MySQL. The exception occurs sometime, not often. I think that I use dynamic incorrectly. After set datasource, I clear the datasource in the threadlocal. So what's the problem?

I upgraded from Alfresco 3.4.d (community) to Alfresco 4.0.d (community). The upgrade process didn't show any errors.
The CIFS access and all the APIs, webscripts etc work fine. Also the Share app works. But when I try to access the /alfresco web app (Explorer) I get the error:
java.lang.ClassNotFoundException - org.apache.opencmis.browser.BrowseServlet from BaseClassLoader
I found out that this class is present in the previous version (3.4.d) in the opencmis-test-browser library. This lib doesn't exist in the 4.0.d version.
Can anyone help me with that? Why am I getting this error? Any idea how to fix it?

Thanks for any hint.
Found the problem - the class package has changed in 4.0.d.
It has changed from org.apache.opencmis.browser.BrowseServlet to org.apache.chemistry.opencmis.browser.BrowseServlet
Changing this in the web.xml has resolved the problem.

if i remove this property no exception is occurred.
My code is like below :
#Service
Class ABCServiceImpl
{
#Transactional
void methodA()
{
// called the method in DAOImpl package -- methodB().
}
}
#Repository
Class ABCDAOImpl
{
#Autowired
SessionFectory s;
void methodB()
{
// hibernate operatoion
}
}
Thanks in advance.
Try to close the connection manually. and
use .openSession(); method to open session instead of .getCurrentSession(); no exception comes.
The problem is that you cant call close() twice on a Session, the second time you call the close() method, it will throw that Exception.
By setting auto_close you are implicitly closing the session after you use it, so the solution would be removing the close() methods in your code, or just remove that auto_close config and close the sessions manually after using them.
If this flag is set to true then session will be automatically closed during the after completion phase of the transaction. Agree with Edward on what you are trying to implicitly close the connection throwing that Exception.
I'm looking for an expert's input on this problem.
I have a java application that connects with remote system via SOAP API. We have this same application (client) running across multiple laptops and hitting various environments (dev, test and production) as required. All is fine except in one laptop in which requests to production (only) fail intermittently. The exception I'm getting is given below:

Do you have any idea what might have happened? To remind you, this happens in only one of many laptops running the same code and config, only in production environment (It's working great in all other environments. There never is any problem), and only at times.
One more thing: if I make calls using SOAPUI from the same laptop, there's no exception.
Your time and response is very appreciated.
Thank you.
EDIT
Additionally, there's one message that keeps popping on this particular laptop only (in eclipse log). I'm not sure this could be a reason though:
Mar 14, 2013 12:19:30 PM org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver handleHttpRequestMethodNotSupported
WARNING: Request method 'HEAD' not supported
Sounds unlikely, but it was because of JDK version. We downgraded JDK version from 1.7 to 1.6 and it worked flawlessly.
Turns out, we banged our head for a whole month to later find out it was version incompatibility :o
Based on the information given, the root error is:
Request method 'HEAD' not supported
You can tell your controller to support the HEAD method using setSupportedMethods(String[] supportedMethodsArray).

You have not really specified your environment, or shown any of your configuration, but from your stack trace I can see that you are using Spring.
In your spring config xml file, you probably have a "dataSource" bean or something similair to the following:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
Try adding the following property to that bean:
<property name="validationQuery" value="select 1" />
This property is explained here: DBCP Configuration
