Stop/Start Contexts with Sessions & java.io.Serializable
hello,
When I stop a context I get the following error:
<!----
2003-04-15 11:09:07 StandardManager[] Cannot serialize session attribute

Now the session attribute progressBar is a bean called ProgressBar.java and
it implements Serializable & another interface class that doesn't implement
Serializable. IS this the problem?? That the interface doesn't implement
Serializable.
Cause these messages are just filling up the log file....Then when I start
the context again I get the reverse error message:

Re: Stop/Start Contexts with Sessions & java.io.Serializable
Posted by Jon Wingfield <jo...@mkodo.com>.
Somewhere in progressBar there is a
org.apache.tomcat.util.log.SystemLogHandler instance variable, which i'm
guessing is not serializable.
Using an interface which does not extend Serializable should not be an
issue because you are controlling the implementation ;)
That said, it is possible to define non-static fields on interfaces so
that each implementing class has access to it.
eg
<snip>
public interface LoggingStuff {
public Log log = new Log("myLog");
void log(String stuffToLog);
}
</snip>
The log instance variable is instantiated before the constructor of your
implementation class is executed.
To my mind this is evil coz the implementation is being forced onto the
interface but it takes all sorts ;)
