General answer to all: You guys break me up. As I recall Arachnophilia is careware. Where is all your caring? And it is free. That's means don't be so demanding -- you got your money's worth. As to OP topic (remember the OP?), as a teacher I find it easier to teach a while(true) [with break] to get students running with a valid program (all those usages being valid) and then expand on better ways to do any given thing. In this case it results in code Paul suggests. Paul: what you say is true, but one can't always impose strict academics on students who are struggling with a sea of ideas, programming constructs, and new ways of thinking. We start them in the wading pool. Those who don't drown there get to try the deep end later. I'm sure you wouldn't like my classes, but I'm not sure my students would like yours. By like, BTW, I mean enjoy the actual learning of programming enough to spend the time and thought needed to actually understand it. To you other guys: lighten up. So you did it baby-fashion. So it works. Okay. But now learn from the master (or at least one of them here) and move on. Stop defending and attacking on such a dumb question. There are going to be better ways of doing just about anything you care to mention; otherwise we CAN close the patent office. As for me, I don't care how it damned thing is coded -- just that it work. Optimization comes ... uhh ... last. -- Gary --- Outgoing mail is certified Virus Free.

There really is a serious difference between break/continue (including labeled break/continue) and goto. It can be debated whether that difference fixes the pitfalls of the goto statement, but it's useless to deny that the difference exists. That difference is that while break/continue can be used to exit a block of code from an arbitrary point, it cannot be used to enter a block of code at an arbitrary point. There is a very strong case to be made that it's the latter -- arbitrary entry points to a block -- that is most threatening to readable code. The former is a natural abstraction in many programming scenarios, esp. when try/finally is used judiciously as well. For the record, though, in at least the specific case of reading from an InputStream, the universal idiom of "while ((len in.read(buf)) != -1)" is far easier to follow, simply because an average Java programmer will already know what to expect. -- www.designacourse.com The Easiest Way to Train Anyone...

Above is the message as I received it. Checking the source it also reads as above. I have been seeing a number of posts, very random, that have words concatenated as the "familiarandreadable" above.

IMHO, this is a very bad approach to teaching structured programming. For such a class, I would outlaw while(true), break, and continue, since all programs can be written without them, and since they are only present in the language to ease the transition into structured programming for those with no background or adeptness in it. > In this case it results in code Paul suggests. > > Paul: what you say is true, but one can't always impose strict academics > on students who are struggling with a sea of ideas, programming > constructs, and new ways of thinking. That happens to be the best, and possibly last, opportunity to impose a necessary discipline, for reasons it is difficult to convey to students, most of whom think a working program is the ultimate goal (if that were true, BASIC would have been the ultimate language). The issue being discussed is at the heart of structured programming. I find it is best to focus on this issue early on, with great attention paid to details. > We start them in the wading pool. > Those who don't drown there get to try the deep end later.

I thought you were being serious. You will either return to the topic, or you will be killfiled. It is your free choice, and your move. If you had any knowledge of programming, you would understand what is being discussed in this thread. If you had an argument, you would present it. I have already presented mine: Disabling "while" by applying "true", thus creating an unconditional block not provided by the language, then repairing the broken result with "break", is a hack, one that violates the most basic paradigm of structured programming. -- Paul Lutus http://www.arachnoid.com == 12 of 13 == Date: Sun, Sep 12 2004 10:01 pm From: Andrew Thompson <[EMAIL PROTECTED]> On Mon, 13 Sep 2004 00:41:09 -0400, Gary Labowitz wrote: > "Jacob" <[EMAIL PROTECTED]> wrote in message news:... >> Paul Lutus wrote: >> >>> As I have already said, once you have seen this pattern ten thousand > times, >>> it begins to seem familiarandreadable. > ..I have been seeing a number of posts, very random, that have words > concatenated as the "familiarandreadable" above.

Don't worry Gary, you are currently at 'a couple of times', but once you have read familiarandreadable ten thousand times it will be familiarandreadable and you will wonder how you ever got by without the expression. ;-) -- Andrew Thompson http://www.PhySci.org/ Open-source software suite http://www.PhySci.org/codes/ Web & IT Help http://www.1point1C.org/ Science & Technology == 13 of 13 == Date: Sun, Sep 12 2004 10:03 pm From: Paul Lutus <[EMAIL PROTECTED]> Jacob wrote: > Paul Lutus wrote: > >> As I have already said, once you have seen this pattern ten thousand >> times, it begins to seem familiar and readable. > > I prefer making code understandable for those that have > *not* read my code 10-thousand times. I prefer using the language as it was intended to be used, consistent with the principles of structured programming. Rule 1. If you use "while", you must test something. If instead you use "while(true)", you are disabling the clause and creating an unconditional block, a structure not provided in the language for a reason. After this mistake, all you can do is add another mistake: a "break" that has no purpose except to try to repair the earlier mistake. > That's the majority after all. The what?

This 3rd party application is running on a different server (may not be Java based). I have stored the usernames and passwords for this app in an external LDAP server. So, I can retrieve them, encode them in Base64 and send the header via a URL Connection. Here's my code: URL url = new URL("http://some.external.server/loginpage";); URLConnection postUrlConnection = url.openConnection(); postUrlConnection.setDoOutput(true); postUrlConnection.setUseCaches(false); postUrlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); postUrlConnection.setRequestProperty("Authorization", "Basic c3lSTdGVduwWlYmwvZ2xj"); //I cannot call connect() if I need to read the stream - WHY? //postUrlConnection.connect(); InputStream postInputStream = postUrlConnection.getInputStream(); BufferedReader postBufferedReader = new BufferedReader(new InputStreamReader(postInputStream)); String postline = null; while((postline = postBufferedReader.readLine()) != null) { out.println(postline); } The servlet is able to login to the application, and it is returning the page that I am suppose to see as if I log in directly thru the URL. I have 2 problems: 1. The returned page has images, files, and URL links that is relative to the server I am connecting to. But, the client is actually connected to my servlet on my machine. So, all the links are broken and I can't get the images. Do I need to do URL re-writing for the images/links to work? Can I do a sendRedirect() on the response and yet still authenticated to the server? 2. I copied an URL that I know exist on the application to the browser. Since my servlet (not the browser) was sending the auth header, I was not able to go to that page on that application. The application is asking me to login again with the Basic Auth dialog. This tells me that the browser did not send the authorization header on my next request. How do I store the authorization header created by the servlet INTO THE BROWSER, so that it will be sent on all subsequent requests? Please help.

It must calculate the max of the three system and user numbers.

There has to be a counter for the number of times it runs until it matches. Here is what I have so far, but I can not get it to return the max.

Can anyone let me know how I can set classpaths using Ant, I seem to be doing it the wrong way. thanks. == 2 of 2 == Date: Sun, Sep 12 2004 5:19 pm From: "WJ" <[EMAIL PROTECTED]> I generally use fileset for my classpath. Like this: <classpath> <fileset dir="${lib}"> <include name="${baselib}/xercesImpl.jar"/> <include name="${lib}/xmlParserAPIs.jar"/> <include name="${lib}/xml-apis.jar"/> <include name="${lib}/servlet-api.jar"/> </fileset> </classpath> Also note, I generally use forward slashes instead of back slashes, even on Windows. I've had problems with back slashes from time to time. You may also want to echo what ant thinks your ${lib} dir is. e.g. <echo message="${lib}" /> HTH "El Durango" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > I am writing an ant script which should set the classpaths for the necessary > Jar files. > Here is what I have: > > <?xml version="1.0" encoding="UTF-8"?> > <project name="test" default="compile" basedir="."> > <property name="src" value="."/> > <property name="build" value="build"/> > <property name="lib" value="lib"/> > <target name="init"> > <mkdir dir="${build}"/> > </target> > <target name="compile" depends="init"> > <!-- Compile the java code --> > > <javac srcdir="${src}" destdir="${build}"/> > <classpath> > <pathelement location="${baselib}\xercesImpl.jar" /> > <pathelement location="${lib}\xmlParserAPIs.jar" /> > <pathelement location="${lib}\xml-apis.jar" /> > <pathelement location="${lib}\servlet-api.jar" /> > <pathelement > location="${lib}\commons-fileupload-1.0.jar" /> > </classpath> > </target> > </project> > > However this is not working, as it fails with unresolved symbol errors. > > Can anyone let me know how I can set classpaths using Ant, I seem to be > doing it the wrong way. > > thanks. > > > ========================================================================== TOPIC: What's the additional value of 'EnumMap' ? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/731db423dd8a0ec2 ========================================================================== == 1 of 1 == Date: Sun, Sep 12 2004 3:25 pm From: Lasse Reichstein Nielsen <[EMAIL PROTECTED]> noname <[EMAIL PROTECTED]> writes: > He probably means the algorithm is optimized for never having a hash > collision, so it never has to check the list of values at each > bucket. Indeed. It is a simple array, with only (at most) one value at each index. I haven't checked HashMap, but a typical hash map implementation would have (linked) lists as entries in the array. /L -- Lasse Reichstein Nielsen - [EMAIL PROTECTED] DHTML Death Colors: <URL:http://www.infimum.dk/HTML/rasterTriangleDOM.html> 'Faith without judgement merely degrades the spirit divine.' ========================================================================== TOPIC: java equivalent of perl module Locale::SubCountry? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/b803837211c1c4ca ========================================================================== == 1 of 4 == Date: Sun, Sep 12 2004 5:50 pm From: vturner <[EMAIL PROTECTED]> Perl has a nice module that converts state province codes for various countries between a three-char code and the fully expanded name. For example, Australia (country code "AU") is composed of several states or provinces, kind of like states in the US. Two of the provinces are "QLD" for "Queensland" and "NSW" for "New South Wales". I need something that can take an input of "Queensland" and return "QLD" and vice-versa. I'm working on a java interface to USPS's online shipping tool and they expect a country code of "AU" and a State code of "QLD". However, the person entering the information on the web site may choose to put in "Australia" and "Queensland" for the country and state/province code, respectively. I can probably use java.util.locale to go back and forth between "AU" and "Australia", but I can't find an equivalent way to go back and forth between "Queenslands" and "QLD". Does any one know of a Java class/package like this? some documentation on the perl module is described here: http://www.cpan.org/modules/by-module/Locale/Locale-SubCountry-1.34.readme == 2 of 4 == Date: Sun, Sep 12 2004 8:25 pm From: Sudsy <[EMAIL PROTECTED]> vturner wrote: <snip> > Does any one know of a Java class/package like this? I don't, but you could always pull down the ISO codes and write something which uses a HashMap or similar construct to achieve your goal. == 3 of 4 == Date: Sun, Sep 12 2004 9:02 pm From: vturner <[EMAIL PROTECTED]> Sudsy wrote: > vturner wrote: > <snip> >> Does any one know of a Java class/package like this? > > I don't, but you could always pull down the ISO codes and write > something which uses a HashMap or similar construct to achieve > your goal. Yeah, but the whole idea is to avoid having to reinvent the wheel. It's one thing to maintain a mapping between 100 or so country codes and their respective names, and another thing to keep track of all the province codes within each country. There's multiple provinces in each Country and most of them are pretty esoteric -- it would be very difficult to know if you've caught everything. I think what I might end up doing is just calling, from a Java program, a perl script that invokes the perl module (using Runtime.exec() ) and just pass back the info either via file or InputStream. == 4 of 4 == Date: Sun, Sep 12 2004 9:42 pm From: Paul Lutus <[EMAIL PROTECTED]> vturner wrote: > Sudsy wrote: > >> vturner wrote: >> <snip> >>> Does any one know of a Java class/package like this? >> >> I don't, but you could always pull down the ISO codes and write >> something which uses a HashMap or similar construct to achieve >> your goal. > Yeah, but the whole idea is to avoid having to reinvent the wheel.

So use the Perl database, dump its contents and create a Java version with the same information. > > I think what I might end up doing is just calling, from a Java program, a > perl script that invokes the perl module (using Runtime.exec() ) and just > pass back the info either via file or InputStream. There really is no need for something like this. You may be able to read the Perl files directly and glean the required information, and create a Java class to handle this issue. -- Paul Lutus http://www.arachnoid.com ========================================================================== TOPIC: How to invoke jar cammand in the java source code? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/1ba789da4111ad18 ========================================================================== == 1 of 2 == Date: Sun, Sep 12 2004 8:06 pm From: wangyin <[EMAIL PROTECTED]> How to invoke jar cammand in the java source code?
