What I bring out of that, which modifies my general understanding, is that there's a difference between what we mean by "type" in the context of the Java language, and in a general OO context. The two are related, and overlap considerably, but are not identical. That makes this much more tricky to use in conversation. A good point is made that objects can be said to have "type" in general OO theory, despite the fact that a Java expression can never refer to them directly and so that type never needs to be used in Java. -- www.designacourse.com The Easiest Way to Train Anyone...

Perhaps. Denizens in java land are prone to a java slant on OO terminology and context, as are any language denizen. But I think that this mismatch in notions is consistent across nearly all OOPL's, imho particularly statically typed ones. > The two are related, and overlap considerably, but are > not identical.

I'm not sure I read precisely that last point. Perhaps because everything is "a pointer to". But for me to attempt a clarification is going to bifurcate this thread beyond all reason :) . That's the nature of this term. Many in usenet are so confident that they have the strongest handle on this term that arguments ensue, not about the definition of the term, but /caused/ by a misunderstanding of what the other was trying to say /because/ of a difference in definitions. -- It'salwaysbeenmygoalinlifetocreateasignaturethatendedwiththeword"blarphoogy" . ========================================================================== TOPIC: Why does this work for Canvas but not for JPanel? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/42cf2394a0e56b78 ========================================================================== == 1 of 2 == Date: Sat, Sep 25 2004 7:27 am From: Andrew Thompson <[EMAIL PROTECTED]> On Sat, 25 Sep 2004 13:22:02 GMT, Jonck wrote: >> Please shorten the lines in your posts, news clients >> generally wrap at 72 chars. > > Ok, sorry about that.

You are forgetting to paint the background, it has become your repsonsibility since you overrode paintComponent() You can either. // call the parent's implementation before you paint super.paintComponent( g ); .. ..or // paint the background yellow yourself.. Color tempColor = g.getColor(); g.setColor(Color.YELLOW); g.fillRect(0,0, this.getBounds().width,this.getBounds().height); g.setColor(tempColor); .. BTW.

The JPanel class does it slightly differently, clearing of the background is done in its paintComponent method. So as Thomas suggested, adding a super.paintComponent() call at the start of the paintComponent method should take care of that. The setSize() call in the Panel constructor also needs to be changed. You should use the setPreferredSize to set a preferred size.

That's pretty much it. java.lang.Object also defines some useful common behavior for all objects, such as comparisons and debug output representations. -- www.designacourse.com The Easiest Way to Train Anyone...

Perhaps another good idea in applying in general is to supply a cd-rom with a fully blown application that you've written on the side. And make it glitzy as hell using skinning. To the side of the interview process, my favorite idea (for resume submittal) is instead of placing the phrase "references available upon request" in your resume, supply a sheet with 7 reference /quotes/ from your 7 greatest fan co-workers. A sentence or 2 or a paragraph, as in the first page of novels, extolling your abilities just shy of nauseum :) "This guy taught me more about OO than 10+ prior years of world experience. He did this and that {etc....}" Dwight Shmidlap, principal architect Smedly Corp, [EMAIL PROTECTED] 123-456-7890 x123 And then they'll be faced most resumes with unknown references, and then yours which 7 known opinions, and names and emails to go with them. This works in another way too. People often dread checking references, and often don't do them at all. When you supply them ahead of time, you'll have references in their heads, and the others might not get checked at all. You'll appear as a /known entity/. A bird in the hand, to overuse a metaphor.

As most of you remember, J2SE was a major platform upgrade from the previous JDK 1.1 family. Two and half years in development and 15 component JSRs later, Sun returns to New York to celebrate the release of the latest J2SE release, v 5.0 (code-named "Tiger"). J2SE 5.0 includes the first source-level language updates in over nine years since the inception of Java technology. Many exciting enhancements for monitoring and management, stability, performance and rich desktop clients can be found in JDK 5.0 and the JRE 5.0. Sun would like to invite all members of the NYJavaSIG, the dedicated Java software developer, to a celebration of the release of J2SE 5.0 in our Midtown Manhattan office. Beer, Wine, Soda, Munchies and some cool giveaways. Looking forward to seeing everyone.

I want to write it as a java application, but be able to output program-generated .html into an Internet Explorer window. Sending the generated html to the IE window is easy... just using the Runtime class. But I want the Internet Explorer window to be able to make http calls back to my application for form submissions. I didn't want to have to force my users to install Tomcat just so the internet explorer could pass back information to the servlet in my .Jar file. How hard is it to add a servlet container and respond to http post's from the localhost internet explorer window? This is all from my .jar file and not from a web application running under tomcat remember. The only http requests coming into my application will be from that one internet explorer window... so its really acting like a single-user-local-machine Tomcat server. But I dont want the burden of forcing Tomcat on people. I suppose you'll say pick a standard application or a jsp/servlet solution, but not both.... but I think there is a lot of flexability to this method, being able to generate GUI screens on the fly in the IE window is really exciting.

And this one was set to 1.3.1. That's the reason why I wasn't asked while installation on Mac OS which JVM I want to use because the Installer already knew it. This is different on Windows and Linux: the end-user has to choose a JVM from a list during installation process. And when I choose a JVM < 1.4 it doesn't work neither!

This is the output of JDE debug attached 7230 handleld: ========================================= CMM: SyncContact no sig from 0x33 debug ------------->>>>>> 2-content length:1385 debug ------------->>>>>> 3 debug ------------->>>>>> 4 VM:+GC(T) RX=174K,RF=284K,FF=6240K,HF=28322,OS=1673K,ON=16K ,OR=15,FR=556,HR=11,IS=1K RA=1010K,RS=393K,RN=4K TA=1449K,TS=1104K,TN=8K PA=176K,PS=176K,PN=2K R0=178K,2=7K,3=20K,7=5K,8=3K,9=410K,10=2K,12=46K, 13=7K,15=24K,16=308K VM:+PPO VM:-PPOc=26,n=1601,s=1K,r=0 VM:PPOt=12,g=5,p=7769 VM:+RSF VM:-RSF VM:+RR VM:-RR VM:+CSF VM:CSF VM:CSF VM:CSF VM:CSF VM:CSF VM:-CSF RX=184K,RF=696K,FF=6330K,HF=28354,OS=1515K,ON=14K ,OR=0,FR=0,HR=0,IS=1K RA=598K,RS=0,RN=0 TA=1360K,TS=1340K,TN=10K PA=175K,PS=175K,PN=1K R0=178K,2=7K,3=20K,7=5K,8=3K,10=2K,12=46K,13=6K,1 5=24K,16=308K VM:-GCt=1333,b=1,r=0,g=3,u=0,c=1 VM:+CR VM:TI2R VM:-CR=3 VM:+GC(F) VM:-GCt=54,b=1,r=0,g=1 VM:+CR VM:TR2I VM:-CR=1 =========================================== Later I change "outputStream.write(dataToSend);" in "for (int i = 0, l=dataToSend.length; i < l; i++) { outputStream.write(dataToSend<i>); outputStream.flush(); } outputStream.close(); outputStream = null;" but it works at the same way. I can't understand.... Connection Buffer? Connection Timeout? Thanks & thanks & thanks.... for any suggestion. fabius ========================================================================== TOPIC: xdoclet entity and dao help http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/51485373c1a7d27b ========================================================================== == 1 of 1 == Date: Sat, Sep 25 2004 2:39 pm From: William Zumwalt <[EMAIL PROTECTED]> I'm learning to work w/ DAO's and have this question. I'm trying to pull my database code out of my entity and and make use of DAO's. My DAO class is being generated from my entity by xdoclet, even though there's not much in it. I have the following in my entity bean ... /** * @ejb.create-method */ public String ejbCreate(String id, String desc) throws ejbCreateException { HashMap memento = new HashMap(); memento.put(SERIAL, serial = id); memento.put(DESC, description = desc); MyDAO.create(memento); return serial; } My question is how do I define (in this case) a create() method of my DAO which will look something like this (but hasn't been generated yet) ... public abstract class MyDAO { static public void create(HashMap data) throws PersistanceException { CreateThing.getInstance().execute(data); } } I saw the @dao.call, but not sure how to use it. Any help much appreciated.

I need a Data Structure that would let you insert Strings into it and give you back an index you could use later on to refer to the inserted String and it should work the other way around too, given the String it should return to you the index if the String exists. In my code trials I have noticed that: 1._ Yes, a LinkedHashMap is really fast if you have the index, but you can not get an iterator from it and, it is really slow when you effectively loop over it via: get(new Integer(Ix)) 2._ A LinkedList is faster but still in order to get to an item you must get an iterator and go over all of them and check them one by one I am thinkign of using a class containing two Maps in order to solve the problem, but there might be a more elegant solution to this prob. == 2 of 2 == Date: Sat, Sep 25 2004 3:38 pm From: Thomas Kellerer <[EMAIL PROTECTED]> Albretch wrote on 26.09.2004 00:23: > > Is there such a thing? > > I need a Data Structure that would let you insert Strings into it and give you > back an index you could use later on to refer to the inserted String and it should > work the other way around too, given the String it should return to you the index > if the String exists. > ArrayList is exactly what you need. Have a look at the add(Object) and indexOf(Object) methods. http://java.sun.com/j2se/1.4.2/docs/api/java/util/ArrayList.html Thomas ======================================================================= You received this message because you are subscribed to the Google Groups "comp.lang.java.programmer". comp.lang.java.programmer [EMAIL PROTECTED] Change your subscription type & other preferences: * click http://groups-beta.google.com/group/comp.lang.java.programmer/subscribe Report abuse: * send email explaining the problem to [EMAIL PROTECTED] Unsubscribe: * click http://groups-beta.google.com/group/comp.lang.java.programmer/subscribe ======================================================================= Google Groups: http://groups-beta.google.com
