According to its charter, this unmoderated group is for immediate help on any Java problem, especially when the source of the difficulty is hard to pin down in terms of topics treated on other groups. This is the appropriate group for end-users, programmers and administrators who are having difficulty installing a system capable of running Java applets or programs. It is also the right group for people trying to check their understanding of something in the language, or to troubleshoot something simple. comp.lang.java.programmer Programming in the Java language. An unmoderated group for discussion of Java as a programming language. Specific example topics may include: o types, classes, interfaces, and other language concepts o the syntax and grammar of Java o threaded programming in Java - sychronisation, monitors, etc. o possible language extensions (as opposed to API extensions). The original charter said that discussion explicitly should not include API features that are not built into the Java language and gave examples like networking and the AWT. These days AWT belongs in clj.gui, and networking is often discussed in clj.programmer. Do not post binary classfiles or long source listings on any of these groups. Instead, the post should reference a WWW or FTP site (short source snippets to demonstrate a particular point or problem are fine).

I am facing a peculiar problem. I have a target timework. <target depends="init" name="timework"> <javac debug="${debugInfo}" deprecation="false" destdir="${ANT_BINARIES_DIR}" srcdir="../src"> <classpath refid="ecp.class.path"/> <include name="com/cbb/cup/timework/**"/> <patternset> <include name="com/cbb/cup/timework/**/test/*" if="buildTestSources"/> <include name="com/cbb/cup/timework/**/*Test.java" if="buildTestSources"/> <exclude name="com/cbb/cup/timework/**/test/*" unless="buildTestSources"/> <exclude name="com/cbb/cup/timework/**/*Test.java" unless="buildTestSources"/> </patternset> </javac> </target> In the com.cbb.cup.timework.business folder there is a file GlobalErrors.java, that a lot files in the com.cbb.cup.timework folders use. However this file is not getting compiled before the other files, and hence all the files give errors that GlobalErrors.ERROR_CODES is not resolved. Using the -debug option I have found that Ant is actually listing the GlobalErrors.java file to be compiled. Only it does not seem to understand that this file is used by others, and hence has to be compiled first. This was not happenning before, as Ant was somehow sorting out which files to compile first. How can I force Ant to compile this particular file first before the other files? Could this be a bug? Any help would be greatly appreciated.

At first, what I struck me as valuable was that type parameters allow one to express constraints that cannot (or not easily) be expressed using simple polymorphism. (An example would be a generic sort method that only accepted a collection if its members were comparable with themselves, cf. http://www.mindview.net/WebLog/wiki-0050) However, when I learned about the type erasure implementation of generics, it seemed to me that the added expressiveness was of no use to people designing frameworks and libraries. After all, there is no generic run-time type information in the jar-file you'll eventually distribute. So, for example, you could not create a library containing a sort method with the above restriction - not even if you required clients to use the Tiger jre. I then read about NextGen, and the possibility of including run-time generic types in Java (e.g. http://www.cs.rice.edu/~eallen/papers/nextgen-final.pdf) Is anything like that planned by Sun for a future Java release? If not, there seems to be little gain in using Java generics for framework development. -- Sebastian == 2 of 2 == Date: Thurs, Oct 7 2004 3:10 am From: "Chris Uppal" <[EMAIL PROTECTED]> Sebastian Millies wrote: > However, when I learned about the type erasure implementation > of generics, it seemed to me that the added expressiveness was of no > use to people designing frameworks and libraries.

It's just that it isn't used by the JVM itself, only by any 1.5-style compiler that is compiling against those jar files. There are a bunch of new "attributes" added to classfiles generated by the new compiler, some of which provide type information for generics. The compiler knows how to read and use that data when if is compiling code that uses the classes. (After all, uses of the newly generic standard library are type checked, so it clearly possible ;-) -- chris ========================================================================== TOPIC: serialize generic objects to XML? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/623165071345a4aa ========================================================================== == 1 of 1 == Date: Thurs, Oct 7 2004 2:51 am From: "Richard Chrenko" <[EMAIL PROTECTED]> On Thu, 7 Oct 2004 18:57:59 +1000, Brusque <[EMAIL PROTECTED]> wrote: > > "Richard Chrenko" <[EMAIL PROTECTED]> wrote in message > news:[EMAIL PROTECTED] >> I currently use ObjectOutputStream in order to serialize my objects. >> However, in order to test and debug my code I really need a >> human-readable >> output format.

Unfortunately my classes implement custom serialization which, according to their website, codehaus does not support. I have also tried the demo version of JSX which declares as a "feature" that it serializes all attributes (even of parent classes not implementing Serializable.

You are aware that there exist text formats other than C, Java and LaTeX, and platforms other than Linux and MS-Windows? I like to use the same text editor for all kinds of text, including mail and news messages, and on all platforms.

It provided a more "inside" perpective to the emacs development, and suggests that the development won't be accelerating any time soon. For me, an important part of the appeal of emacs has been the "future-proof" quality, but if the development is stagnating, well, it just doesn't feel that future-proof anymore.

I don't think the article is aimed at "convincing" anyone - what would be the point, anyway? One might hope that the critique of emacs (or the state of it) might lead to some discussions in the emacs developer community, perhaps even a "renaissance" of some sort, reunification of emacs and xemacs, and world peace (that'll be the day).

I also prefer Python, by far. If emacs was in Python, it would have *much* more contributors and extensions. Lisp is an integral part of the emacs community, and that's probably not going to change, so I, like the author of the article, did some soul-searching and wondered whether emacs is where I want to be in the future. I'm going to keep on using it until Eclipse matures up a bit more, which might take a few years, but I'm trying to refrain from getting too involved with configuration and implementation of extensions. I don't particularly like Java, or consider it a better editor extension language than elisp, but with Eclipse I think the *need* to hack the editor is lower. -- Ville Vainio http://tinyurl.com/2prnb == 3 of 3 == Date: Thurs, Oct 7 2004 3:52 am From: "Darryl L.

MS verwendet undank der kleinen Unstimmigkeiten mit Sun eine MSVMS, die auf Java Version 1.1.4 aufsetzt, die ist dummerweise Baujahr '97 und gehört eigentlich ins Museum. Ich würde mein Applet (das die Navigation einer Homepage ist und leider sehr arbeitsintensiv war) aber gerne überall sehen - wer kennt einen Download Link zu dieser JDK Version oder hat sie zuhause und kann sie irgendwo hin auf nen Server stellen, mailen, ich hol sie auch ab und bring ein Bier mit wenn's sein muß...

Höchstwahrscheinlich hast Du sie doch schon, mußt halt nur das Sun-Plugin für IE deaktivieren. == 3 of 4 == Date: Thurs, Oct 7 2004 4:21 am From: Thomas Weidenfeller <[EMAIL PROTECTED]> werner55 wrote: > Hallo, > ich habe heute Nacht um 2 entsetzt herausgefunden, ... das du in der falschen Gruppe oder in der falschen Sprache schreibst?

Most of you can guess the rest, so I'll have the rest translated by Google and hope for the best.. <http://translate.google.com/translate?u=http://www.physci.org/codes/javafaq.jsp&langpair=en%7Cde> Merken Sie besonders die Hinweise auf applet und Internet Explorer. Lesen Sie es allen. Es gibt andere Werkzeuge auf meinem Aufstellungsort zum Helfen, applet zu entfalten und beschäftigt IE. Haben Sie einen Blick an den Verbindungen auf dem links. Merken Sie auch, daß Sie zu einer Gruppe bekanntgaben, in der Leute im Allgemeinen Englisch schreiben, selbst wenn sie in ihrer Muttersprache bekanntgeben auch müssen können, um sich klarzustellen. Ich finde das Google, die Werkzeuge zu übersetzen, die, um Kommunikation zu unterstützen ziemlich handlich sind, wenn Sie zu dieser Gruppe bekanntgeben müssen und nicht englisch sprechen, ich vorschlage stark, daß Sie sie verwenden. Schließlich gibt es auch gute Javagruppen für deutsche Lautsprecher, wie ich verstehe. ..you nicht gerader Pfosten hier tat Sie versehentlich (Rollenaugen) OH- und Versuch zum nicht Lachen, als Sie die Übersetzungen lasen. ;-) -- Andrew Thompson http://www.PhySci.org/codes/ Web & IT Help http://www.PhySci.org/ Open-source software suite http://www.1point1C.org/ Science & Technology http://www.lensescapes.com/ Images that escape the mundane ========================================================================== TOPIC: Scientific Dogma http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/8beff1743cc2327 ========================================================================== == 1 of 1 == Date: Thurs, Oct 7 2004 4:07 am From: [EMAIL PROTECTED] (Dave Monroe) nog <[EMAIL PROTECTED]> wrote in message news:<[EMAIL PROTECTED]>... > On 6 Oct 2004 15:58:13 GMT, Alexander Mulligan wrote: > > > "nog" > > > > 5 lines with no quoted material in response to > > a 150+ line post on a serious subject? > > > > Post ignored, as will any subsequent posts by you, > > and any responses to them. > > > > My newsreader is a troll-free zone. > > > > [...] > > > > <+> > > As soon as you trotted out the age=wisdom mantra, all pretence at being > serious was lost. > Anyway, I haven't been kf'd in ages.

I want to accomplish a "docking window" effect. I want to be able to click on a JSplitPane and have it resize the Window. For eg: I want to have a window which contains 2 panels. The left panel should always be displayed. When the user clicks on the JSplitPane arrow the right panel is displayed and the window increases in size to display a right panel. When the user clicks on the JSplitpane arrow again the right panel disappears and the window resizes to its original size. thanks. ========================================================================== TOPIC: JSP: Session parameters vanish on refresh. How do I keep them on refresh? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/2f5632dd37dfd103 ========================================================================== == 1 of 1 == Date: Thurs, Oct 7 2004 4:33 am From: [EMAIL PROTECTED] (Per Magnus L?vold) Hi! I'm working on a JSP application. Using JDBC I query for a certain background program to finish populating a table. This takes a while, so I am trying to do a refresh page that updates with the latest results. For refreshing the page, I use: *** <head> <META HTTP-EQUIV="REFRESH" CONTENT=30> <title>my page</title></head> *** This does the trick of refreshing the web page every 30 seconds. BUT the problem is that all the parameters I have passed to the page dissappear on the refresh..! So my code stops working. :-( How can I set the parameters so that they still can be retreived after a refresh? The webserver supports servlet 2.0, and I have tried setting the parameters with: *** session.putValue("MyParam","MyValue"); *** When I after refresh try: *** String myParam = (String)session.getValue("MyParam"); *** ...myParam is empty. Hope someone can help me here! :-) Regards, Per Magnus ========================================================================== TOPIC: Looking for HTML Renderer http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/b1a8bdcce8b1d66f ========================================================================== == 1 of 1 == Date: Thurs, Oct 7 2004 5:04 am From: bugbear <[EMAIL PROTECTED]> Xiaolei Li wrote: > Andrew Thompson <[EMAIL PROTECTED]> wrote: > >>On Wed, 6 Oct 2004 22:23:59 +0000 (UTC), Xiaolei Li wrote: >> > > anyway, i think the slight differences between browsers won't matter too > much. any competent renderer will do. > <speculation> IIRC Sun had a native java Browser.
