What he probably wrote (my copy is at home where I can't check it right now) is that factory methods *can* be used as part of an object-reuse scheme. The code you showed does not provide for reuse, but here's one way it could be done: class Thing { /* Don't let outsiders use the constructor */ private Thing() { } /* "Reservoir" is some sort of a container in * which created but currently unused objects * live. */ private static Reservoir stash = new Reservoir(); /* Give the caller a Thing, either newly-minted * or retrieved from the stash. */ public static Thing thingFactory() { Thing it = stash.removeNextThing(); if (it == null) // stash was empty it = new Thing(); return it; } /* When the caller no longer needs this Thing, * releaseThing() puts it into the stash where * it becomes available for reuse. */ public static void releaseThing(Thing it) { stash.insert(it); } } That's a very simple outline. In practice, the factory method might initialize each recycled Thing to a known state (just as a constructor would), and might even take constructor- like parameters. There might be provisions to keep the stash from getting obscenely large; there might even be provisions to let the Things in the stash be garbage-collected at need. The fundamental idea, though, is that an object that is no longer needed isn't just dropped on the floor for GC to sweep up, but is instead held in a "recycle bin" for future reuse. When another instance is needed, the factory method can provide one by dusting off an already-used object instead of creating a brand-new one. -- [EMAIL PROTECTED] ========================================================================== TOPIC: (soft) real-time transfer with Java http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/938017c2d84d8f04 ========================================================================== == 1 of 1 == Date: Tues, Sep 21 2004 12:39 pm From: "szamot" <[EMAIL PROTECTED]> Hi, Is here someone with experience: two-direction (soft) real-time transfer data from database on server computer (for example SQL) to hosts with webbrowser (for example Netscape, IE)? ========================================================================== TOPIC: Getting the Page URI from Custom JSP Tag http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/8e680b92e1eb5a2 ========================================================================== == 1 of 4 == Date: Tues, Sep 21 2004 1:10 pm From: "John Topley" <[EMAIL PROTECTED]> Hi, I'm developing a custom JSP tag library.

Note that JSPs are compiled into servlets, and the container may move them to another location, so if you're looking to load a file that's in the "same directory" or something, don't use this method.

That is what you might expect in Java, but quite the opposite is true: StreamTokenizer isn't very advanced. It says in the docs: "Each byte read from the input stream is regarded as a character in the range '\u0000' through '\u00FF'." So there are only 256 characters to be reckoned for. > Is there no alternative? I just read in the docs that the ordinaryChars() method does the same as resetSyntax(), but only with the specified characters.

That sound about right? About. The most fundamental problem is that constructors are not inherited; so since you don't know what class T really is, you don't know what parameters it requires in its constructor. It may not have a constructor that takes no arguments. -- www.designacourse.com The Easiest Way to Train Anyone... Anywhere.

That's the fishing rod. _If_ he (the OP) does some research and still cannot find an answere, then I'm sure his questions will be welcome at this group. - He also provides a URL which searches Google for Java implementations of Crypt, with the first match being a page that lists several working implementations.

As Will Hartung indicated, it is best to use metrics. If you can run something like a profiler that will allow you to determine what exactly is taking a long time to execute, then you can fix the problem.

I get the error that you see at the bottom there. The thing is I don't get it all the time only once and a while. I have heard that switching between indeterminent mode and determinate mode can cause some resizing problems. I have heard of a solution to set the String to null while in determinate and set it to the empty string when in indeterminate mode. I tried that and it doesn't seem to work. I might have done it wrong. I suspect that I am only running into problems once and a while because the indeterminate bar is in the middle of the progress bar when It exits indeterminate mode causing some problem with the string of non indeterminate mode.
