Hello Bill! Finally I have solid keyborad to type ;) I hate laptop's one ;) > Please don't be confused with event term. Destroy method is actually > the event the servlet receives on container state change. >>I see. So you mean a servlet that would implement the >>destroy method an= d >>perhaps help to make configuration easier? I like >>that. We already (in >>0.7) have a MonitorServlet; why not have another >>servlet for other >>tasks. Like: >>1. Shutting down Proxool >>2. Configuring Proxool from file I didn't mean any certain form of framework. The servlet container is one o= f possible. Let it be. Again, in my case I have framework of absolutely d= ifferent kind. In case of the servlet engine I would sugest a Proxool Con= trol Panel having a form of servlet and swing application or a java bean = with UI customizer. This one should connect proxool or to be forked as a = thread. It shows real-time statistics, may configure a statistics log for= mat. In case of Avalon framework this component could be different but st= ill play the same role. But that's all about proxool tuning. What I meant= exactly is how Proxool react to framework state changes. There are few w= ays to use proxool in servlet container. It may be a singleton serving al= l servlets and it may be a part of one web application serving the needs = of this web application. This is the design issue. It is not possible to = say for sure which way is preferable. I would say that both are. It depen= ds upon technical requirements. So that I assume proxool is a component= allowing to be nested within a custom framework. To pass on framework ev= ents the framework should provide a proxy in between, talking directly to= proxool. If the framework doesn't suppose proxool customization it uses = it transparently like we have already discussed. Regards, Andrew. |

In > this case web application is the framework in which the proxool is > nested. Not the servlet engine! Ok. Let me be clearer. At the moment we have an adapter (if you want to call it that) ServletConfigurator that will do this shutdown for you. It works in Servlet Containers - obviously. I don't see any problem in writing another adapter for other web applications. > When the web application receives Destroy message (destroy method is > called) it invokes shutdownHook of proxool facade. The fail-over is > not responsibility of proxool unless it happens inside of proxool. "Fail-over"? > If mentioned above web application has failed the proxool should > receive the same shutdown message (facade shutdownHook is called) or > another message like reinitialize the pools or what is most fit the > requirements. Andrew, you're going to have to resort to specifics here. This is all a bit vague. I think the API already supports shutdown; the exact mechanism of that shutdown must depend on the environment that Proxool is running in. In what way do you think current Proxool API limits you? (BTW, Andrew, can you include a subject in your messages to this list please.) Regards, -- Bill Horsman Proxool http://proxool.sourceforge.net ICQ: 119577180 |

Hello All! Sorry for missed subject.

I was speaking about pricinpals, not the missing features. Probably it was a bit more theoretical than needed ;) I do not have any limits on using Proxool, just terms are very important when you speak about architecture. Very often people understand the same terms diferenly. So let's skip that. Currently I have a question about transparent support of scrollable cursors. For example ODBC bridge doesn't support result set navigation and result set update. What do you think of that? Sorry for misleading. Andrew. |

What do you think of that? As far as I know, scrollable cursor support will depend on the delegate driver. So if that driver supports it, so will Proxool. When you ask a Statemet for a ResultSet you get the actual ResultSet from the delegate driver (no proxying). I say "as far as I know" because this isn't tested. (Although I believe Bas and Alastair include this in their J2SE compliance test - coming soon). Regards, -- Bill Horsman Proxool http://proxool.sourceforge.net ICQ: 119577180 |

I am not sure it is worth, it depends on final target of your project. It's just an idea. Andrew. |

Like you say, I'm not sure if that is really the objective of Proxool and it does sound quite involved. Still, thanks for the suggestion.
