    Hello Andrus,

    that i have in controller class (struts framework)

    private DataContext createContext() {
        Configuration.bootstrapSharedConfig(this.getClass());
        DataDomain sharedDomain = Configuration.getSharedConfig().getDomain();
        return sharedDomain.createDataContext();
    }

    and when i want to work with DB i make this:

        if( this.ctxt == null ) this.ctxt = createContext();

    but if the web-application (under tomcat) is started for a long time
    ctxt is not 'null' and access to him causes an error

    >>I had following problem.
    >>A bit later after start of a server, i lose connection with a
    >>database. (i think MySQL close unused connections)
    >>In JDBC it was solved through 'pooled connection'
    >>how this problem in Cayenne is solved?

    A> Cayenne does provide connection pooling. From you message it is not quiet
    A> clear though what really happened and whether pooling has anything to do
    A> with it.

    A> Any specific error messages?
