As the message says: possible non-thread safe access.

Try to make sure that only one thread accessing H session. You can do that by using session-per-request strategy or session-per-business-transaction

Hi,
I think its not a prob. becoz every and every requesting we r creating the session. we have writtne this code into the web.xml. we have written like this.
<filter>
<filter-name>OpenSeView</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>

This assumes that every request passes through the filter which might not be the case, for example an jsp:include could be handled by webserver via separate thread that will not go through the filter. Therefore I suggest trying more robust session-per-business transaction approach. In this case session handling happens on DAO layer and such issues are eliminated.
