Spaans" Hi, I don't know if I really understand your point, but I think you're refering to the 'scope' of a variable. A web container has three different scopes: request, session an application. Request is only present during the processing of a single request. Session parameters are available during the lifetime and in the context of the session, and application parameters are valid, and shared over multiple sessions within the context of the application. In your jsp you can use request.getParameter("name"), session.getParameter("name") and application.getParameter("name"). regards, Rogier Spaans milkyway wrote: > Hello there, > > I have heard that one can set a .jsp page so that the content is valid > over an entire session.

Not in a way that helps answering the OP's question. The phone's *maker* determines the font that will be used. The locale is going to be his most important consideration in that decision, but not the only one. He'll want to choose a font that can display all the characters used in that locale, but may not be able to - early mobile phones were too limited in their display resolutions, memory and entry methods to display all the characters used in Japanese, so they supported only the tiny subset of syllabic characters. OTOH there will often be a number of characters added that are not formally part of the "locale" but used anyway. Therefore there *is no* direct, one-to-one mapping from "locale" to a set of characters displayable by any or all phones meant for that locale. > A locale is a > location, and regarding a mobile it's a location where that phone is > meant to be used.

Which is a truism and doesn't answer the question because neither your notion of "locale" nor "be for" is defined formally in a way that would yield the desired set of displayable characters. >>> An example of a local supported by a phone would be those phones >>> manufactured in Korea which have only Korean characters displayed by >>> the font set on the phone. >> >> I rather doubt any of them do not also display latin letters. > > Where did I say anything about Latin? You said "phones [...] which have only Korean characters". Well, there is no such beast.

"based on" is a very fuzzy non-technical expression, pretty useless when seeking answers to clear-cut technical questions. That's why I'm *not* saying that. And that's why I'm trying to avoid the word "locale", becuase the way you're using it, it's equally fuzzy. > But, before you said "[t]he font is what > determines which characters can be displayed on a Java system. Not a > 'locale'" when *I* said it depends on the locale. So, which is it? Both. The characters displayable on a phone are determined unequivocally by the font. If a character is not in the font, the phone cannot display it, if it is in the font, the phone can display it. The font contains any and all of the characters displayable by the phone. The choice of font is *influenced* by the locale, but not determined in an unequivocal way, especially since your concept of "locale" is also fuzzy. Whatever a locale is, not all phones made for it have the same set of displayable characters. >> but that's not really relevant in regard to mathematical symbols, >> because most of them are not part of any natural language. > > So?

Dude, you're going on about the Locale class and saying that my using the word locale, but then *YOU* used the word locale in *exactly* the same way *I* did. WTF?

That's why I didn't say *anything* about the font, and only mentioned the *locale*. Jaysus, what's your problem? > The phone's *maker* > determines the font that will be used. What an unnecessary hair to split. Are you just itching for an argument? The OEM determines what locale is going to be supported by a handset model, and provides the appropriate font to support that locale. <snip> > Therefore there *is no* direct, one-to-one mapping from "locale" to a > set of characters displayable by any or all phones meant for that > locale. When did I say there was a "one-to-one mapping from 'locale' to a set of characters"? Seems I said, quite clearly and simply, the characters that will be displayed will depend on what locale(s) the phone was meant to support. A phone manufactured for Korea is not going to support Big5. You really are sounding like someone who said something foolish, realized it and is now just going to keep arguing nonsense like the above "it's the phone manufacturer" bit. Move on, get over your mistake. >> A locale is a location, and regarding a mobile it's a location where >> that phone is meant to be used. You won't find a phone with Big5 or >> Traditional Chinese being sold widely in the US because that would be >> the wrong locale for using such a device.... > > And what have *character encodings* to do with this debate? They're referred to as *fonts*, the thing which you previously said was important and not the locale (when I mentioned the locale), right before you turned around and said that the locale was what determined the font (which was what I said originally). >> Then perhaps, in future, you should devote just a *wee* bit of time to >> the > > > topic of the person's question.

It said that the characters supported on the phone are going to be determined by what locale(s) the phone supports; i.e., what region the phone was programmed to support. As I've said twice now, an example is a Korean phone that will definitely not display Big5 of Simplified Chinese characters because that's a different *locale*. Now, you'll want to take special care and notice that I used a lower case /l/ when I said "locale" *each time*. I said nothing about a Locale class, since the Locale class is not related to the subject at hand. Do *you* understand? 'Cause it seems to me the OP isn't asking questions about the Locale class so I'm going to guess here that s/he didn't see my single sentence with the lower case /l/ as saying what *you* mistakenly read into it. >> Nothing about classes not available on mobile phones.

What part are you having a problem with? Maybe you were too busy looking for something to argue about to read where I posted that a locale is "[a] geopolitical place or area, especially in the context of configuring an operating system or application program with its character sets, date and time formats, currency formats etc." Notice the "character sets" part of the definition, which I posted *last week*. But, you go right ahead and continue to call my usage "fuzzy" if that makes you feel like you're not bickering about nothing... > Whatever a locale is, not all phones made for it have the > same set of displayable characters. And is that another OEM truism? Just like the above bit where you said that Korean phones will also have Latin characters? >>> but that's not really relevant in regard to mathematical symbols, >>> because most of them are not part of any natural language. >> >> So? > > The original poster asked specifically about mathematical symbols. Which are not necessarily going to be available on the phone. But, if the character set (also called a font) on the phone (as determined by the locale(s) supported) has them, then they'll be there.

Except that there are very, very few (if *any*) phones that allow you to update the font on the phone, and that telling someone such a thing would be beyond misleading since 99.9% (or more) mobiles don't have this ability. Can you name even *one*? Oh, and let's not forget that even if the phone *did* allow you to upgrade the font, the MIDP *doesn't let you specify the font* so it would still be a pointless thing to say. Tell me, do you actually have any experience with the MIDP? Because this is at least the second thing you've said that indicates to me that you're not very well versed in the subject... >> Rather than itching for a Usenet fight, why not look into the subject >> matter or ask someone to clarify their posts rather than unnecessarily >> posturing yourself like you've done in this thread? > > I tried to be helpful and clear up things.

Well, generally you should post a relevant section of code, ideally something short that compiles and has the problem you describe.

The documentation I can find seems to imply that only 1.4 is supported, but it doesn't explicitly say so. It'd be nice to be able to use generics. Has anyone tried the Hibernate 3 alpha? How stable is it? Does it have JDK 1.5 support yet (the roadmap lists that as one of the planned features)? -john ============================================================================== TOPIC: Another simple problem http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/f3052e16ead05747 ============================================================================== == 1 of 1 == Date: Tues, Dec 14 2004 11:25 pm From: "Virgil Green" Tilman Bohn wrote: > On Sat, 11 Dec 2004 16:55:59 +0000, Joona I Palaste wrote: > > [...] >> public class Car { >> public new() { >> /* ... */ >> } >> public new(String model, int year) { >> /* ... */ >> } >> } >> >> you would still call it with: >> Car c1 = new Car(); >> Car c2 = new Car("Toyota", 1996); > > That's even more confusing.

I don't know, but this is a problem that can probably be better addressed by the folks over at Google.

That's the time the system has to spend actually loading the data from the input stream.

Yes, you can instantiate the player without calling start(). > I tried this but it gives me null pointer exception when I call > startplaying() method: That's because you've declared an instance variable: > private Player p; But then in your constructor you created a local variable with the same name: > public ExampleGameCanvas() throws Exception { > > InputStream is = getClass().getResourceAsStream("/res/test.wav"); > Player p = Manager.createPlayer(is, "audio/x-wav"); Here you should instead be doing: p = Manager.createPlayer(is,"audio/x-wav"); And that will fix *this* problem. -- Darryl L.

I'm not aware of any problems with this arrangement.

In this case, you could try something like this: urlSurveyIdInt = new Integer( session.getAttribute( "surveyid" ) ).intValue(); This is very basic Java, BTW.
