Take the following: class Foo { private Foo() {} public static Foo getInstance() { return new Foo() } } How is an object of Foo being reused? All I see is that every time static getInstance is called, it returns a new Foo object. What am I not seeing? Am I missing something underneath the hood that the JVM is checking? One more question - can only immutable class objects be reused? Thanks, Javaguy ========================================================================== TOPIC: Is it possible to alter Ant properties after they've been initialized? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/b49e18141bedfe87 ========================================================================== == 1 of 1 == Date: Tues, Sep 21 2004 4:32 am From: baltrunas <[EMAIL PROTECTED]> I had simple problem: to write "buildAll" task which would use same build.xml with different properties.

Trying: java crypt algorithm shows that the search is too broad, so refining it in the most obvious way: java unix crypt algorithm turns up, as #1: Java Implementations of Unix Crypt This page contains links to Java implementations of Unix Crypt. www.dynamic.net.au/christos/crypt/ which looks promising.

Leaving aside the point that the OP would find it useful to learn to use Google, and similar resources, effectively. I don't think Andrew's focus is entirely on the value to the poster; there is also the value to this community (and yes, there is a community here, albeit somewhat enfeebled these days) of discouraging the constant flow of petty noise. Whether that "mission" is achievable (even partially), or whether Andrew or anyone else has the right to undertake it, are different questions (to which I think the answers are "probably not" and "yes" respectively -- ymmv). But the value to the OP is not the only, nor -- in this case -- the most important question here. Remember: this is /not a helpdesk/. We are /not/ here specifically to help (though we often do). -- chris == 6 of 6 == Date: Tues, Sep 21 2004 2:29 am From: Andrew Thompson <[EMAIL PROTECTED]> On Tue, 21 Sep 2004 10:12:46 +0100, Chris Uppal wrote: (snip) > ...I don't think Andrew's focus is entirely on the value to the > poster; there is also the value to this community Thank you Chris.

I do not see this as 'a war that can be won', I see it is simply 'a necessary act of community mindedness that must constantly be stressed, so that a group does not become inundated in dross'.

While I'm no more impressed than anyone by MS's dismal record of security holes badly patched with security hacks, you are being overly harsh here. MS's standards-breaking error was that they accepted the user:pw@ notation in the first place, not that they later removed it. If you check RFC2616, section 3.2.2 you'll find that it does /not/ allow the @ notation in an HTTP URL, specifically it gives the grammar as: http_URL = "http:" "//" host [ ":" port ] [ abs_path [ "?" query ]] It references RFC2396 (which does mention the @ syntax, but that's a much more general document than RFC2616) for the meaning of 'host', 'port' etc. If it were intended to allow the @ syntax, then it would use different terms from RFC2396; and might read: http_URL = "http:" "//" server [ abs_path [ "?" query ]] where (from 2396): server = [ [ userinfo "@" ] hostport ] hostport = host [ ":" port ] Incidentally, even RFC2396 discourages the use of "userinfo" as a <name>:<password> pair. Quote: Some URL schemes use the format "user:password" in the userinfo field. This practice is NOT RECOMMENDED, because the passing of authentication information in clear text (such as URI) has proven to be a security risk in almost every case where it has been used. -- chris ========================================================================== TOPIC: Verify .java matches .class http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/f0f3cde9fea4611c ========================================================================== == 1 of 1 == Date: Tues, Sep 21 2004 2:19 am From: [EMAIL PROTECTED] (David Davidson) The question though is how do you verify that the class file is the same, it may have the same file size, but how do I know that the internal logic is the same?

Yes. In the discussion, Alpha and Gammas relation to Alpha is irrelevant. For Delta the interface of Gamma is the only thing that matters. Gamma must be public for Delta to extend it from outside its package. Then Delta can override all of Gammas public and protected members (including protectedMethodAlpha). ========================================================================== TOPIC: Fast TIFF reading library http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/62560e8e5fe54c9e ========================================================================== == 1 of 1 == Date: Tues, Sep 21 2004 2:44 am From: "Niels Dybdahl" <[EMAIL PROTECTED]> Which TIFF reading library do you recommend ?

Has it written an object? > At server, i need do a function to forward the object or not? You have created two *independent* object streams, one from the client to the server, and one from the server to the client: client server stream 1: ObjectOutputStream --> ObjectInputStream stream 2: ObjectInputStream <-- ObjectOutputStream Stream 1 and stream 2 are not connected to each other! If the client writes an object to the server, that object is *not* automatically sent back to the client. Is that what you are trying to do? When the client writes an object to his ObjectOutputStream, the server can read it from his ObjectInputStream. If the server writes an object to his ObjectOutputStream, the client can read it from his ObjectInputStream. Note: it is a good idea to always create the ObjectOutputStream before the ObjectInputStream (you did not do this in your server). /gordon -- [ do not email me copies of your followups ] g o r d o n + n e w s @ b a l d e r 1 3 . s e ========================================================================== TOPIC: how can i simulate my pc as http server by writing java code to send the http response by socketstream to some pc in the internet?! http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/d2d914791c738e87 ========================================================================== == 1 of 1 == Date: Tues, Sep 21 2004 2:52 am From: [EMAIL PROTECTED] (mike) regards: I write java code to simulate my machine as a HTTP server,when client connect to my HTTP server,my HTTP server replied client a xhtml file.
