Hi,
I am trying to implement Google App Engine support for Myfaces 2. You
can see the work [1] [2].
At the moment, I am making some trials to identify the problem at [2].
I am experiencing an interesting problem. My filter's static variable
is lost after some time(ie. 3 minutes)
I have a filter like this:
public class TestFilter implements Filter
{
...
private static String myStaticVariable;
public void doFilter(ServletRequest arg0, ServletResponse arg1,
FilterChain arg2) throws IOException, ServletException
{
log.warning("myStaticVariable" + myStaticVariable);
if(myStaticVariable==null)
myStaticVariable = "someValue";
arg2.doFilter(arg0, arg1);
}
...
}
When I make the first request, "myStaticVariable" is set to
"someValue". If I make a request in a short period (ie. 20 seconds), I
see that value of "myStaticVariable" is still "someValue".
However, after 3 minutes, when I make another request, I see that
"myStaticVariable" is set to its default value (null).
Why are my static variables are gone? Am I doing something wrong?
I can understand that the reconstruction of the filter and loss of
instance variables; we are trying to run our application on cloud.
But loss of static variables are completely weird.
I couldn't find an issue on Google Code project, thus wanted to ask
you before opening an issue.
Thanks,
Ali
