- R: JTable and db connectionThere is a good example in JTable example ad www.sun.com. By the way, it is
based on the idea of copying all the records in a Vector array, and then
send all to the JTable...
IMHO this isn't a good approach, but it is a good example to understand the
JTable

- portal library needed ?Hi all ,
I am trying to build a portal which will consist of functions like log
in , user management and some cms stuff and will probably develop more in
the future. So I am trying to search for some portal building library. Has
anyone try one of these portal library like jetspeed, jPorta, liferay ... ?
Is it really that useful ? On what basis should I use one ? As i think the
learning curve maybe quite large that I am sure i can build faster without
it. But I am not sure if I would need it when I further develop the site.
And can anyone share some pros and cons of the library.
Thanks.

Way back, Google's purchase of old Usenet bulletin boards was probably
a good thing (through purchase, I believe, of Deja News). Now with
the continuing evolution of the Internet - with Blogs and associated
RSS feeds, etc. - this type of forum is becoming largely irrelevant
and should be done away with. I would like to thank all of you
nimrods posting this kind of crap on this board for opening my eyes
completely to this fact. Do you actually regard yourself so highly
that you think that people actually CARE to read your constant
blatherings on this and that nonsense?
Every now and then I return to c.l.j.a. just to see if anything of
interest has been posted - kind of like how I leaf through JDJ to see
if they've managed to write a decent article. This will hopefully be
my last visit unless I end up here by mistake or by habit. Thanks
again.

- Infinite loops in hashCode() and equals()What do you think the following fragment prints?:
List l = new ArrayList();
l.add(l);
System.out.println(l.hashCode());
Trick question. The result is an infinite recursion (i.e. a stack
overflow), since the hash code for a List is calculated from the hash codes
of its members.
Likewise, the following causes an infinite recursion, since lists are
defined to be equal when they have the same members.
List l1 = new ArrayList();
List l2 = new ArrayList();
l1.add(l2);
l2.add(l1);
System.out.println(l1.equals(l2));
These cases are simple to spot, but the same situation could occur with any
cyclic graph of objects that compute hash code and/or equality based on the
values of their members. Also, equals() and hashCode() are often called
implicitly, for instance when adding an object to a HashSet or HashMap.
I don't see any way this could be addressed other than by keeping track of
which objects have already been processed by the current hashCode() or
equals() call, and there's no way to do that without changing the method
signatures, to, say, add a Set:
in Object:
public final int hashCode() {
return hashCode(new HashSet());
}
public final int hashCode(Set processed)
{
if (processed.contains(this)) {
return System.identityHashCode(this);
}
else {
processed.add(this);
return this.calculateHashCode(processed);
}
}
public int calculateHashCode(processed) {
return return System.identityHashCode(this);
}
with calculateHashCode(Set) being the method that classes can override and
hashCode(Set) the method List et al. call on their members. And that is a
pipe dream, since it isn't possible to make this sort of incompatible change
at this late date.

- ToolTip for Graphical ItemsHello,
I'm trying to make a tool tip pop up whenever the user does a
mouse-over on a filled rectangle that I've drawn on the screen. I have
no trouble creating the rectangle
Rectangle test = new Rectangle();
And it seems like there should be something like
test.setToolTipText("rectangle"), but as far as I can tell, there's
nothing like that. Is there some way to do this?
Thanks,

- default value of data member.Hi
I have a problem about default value of data member!
+++++++ cut here++++++
class CComputer
{
private double cpu=3.0;
private double memory=1.0;
public void set(double c)
{
if(c<0)
System.out.println("Input cpu error, cpu is default value");
else
this.cpu=c;
}
public void set_memory(double m)
{
if(m<0)
System.out.println("Input memory error, memory is default
value");
else
{
memory=m;
show_memory();
}
}
public void set(double c,double m)
{
set(c);
set_memory(m);
}
void show_cpu()
{
System.out.println("cpu="+this.cpu);
}
void show_memory()
{
System.out.println("memory="+this.memory);
}
void show_all()
{
this.show_cpu();
this.show_memory();
}
}
public class bbb
{
public static void main(String args[])
{
CComputer c1=new CComputer();
c1.set(-3.5,1.5);
c1.show_all();
c1.set(-3.5,-2.0);
c1.show_all();
c1.set(-3.5);
c1.show_all();
}
}
+++++++
The output of "c1.set(-3.5,-2.0);" shows memory=1.5.
The output of " c1.set(-3.5);" also shows memory=1.5;
Why? I thought memory should be default value, i.e. 1.0.
Thank you in advance.

- Just a Great Big Scrollable LineHello,
I am a bit new to java and the java swing GUI.
I am writing a JApplet.
What I am trying to do is draw a line (say from (0, 0) to (1000, 1000)) and
have the applet supply automatic scrollbars so that the user can see the
whole line (sounds stupid - I know, but its a step in my direction).
Anyway, I tried to inherit from a JLabel, change the inherited comopnent's
paintComponent method to draw a line and put the inherited component in a
JScrollPane. However, this only resulted in a Line which was only partially
seen and no scrollbars. Moreover, I discovered that if I just add text to
my label with the setText method then I get auto scrollbars if I make the
applet smaller than the text size. This means that the setText method is
doing something that defines it's boundaries for the JScrollPane to react
to. So, my question is: How do I tell the JScrollPane that my inherited
JLabel is 1000x1000 (and not just the size of the text)?
Thanks,
Aviv.

- Reset button cannot clear fields after displaying error messagesHello
my form extends from ValidatorForm
and making use of validator.xml and validator-rules.xml,
The reset button can clear fields within form

- UTF 16 (byte[]) <--> String?Hi,
is there a convenient way to convert unicode that's stored in byte array to
java String?
and vice-versa?
e.g. for a single single unicode,
the higher byte would be in byte[0],
lower byte[1]
and byte[2], byte[3] = 0. null terminated
the byte array of unicode is generated from a C program and transfered over
the network ..
looking over the String API doesn't reveal much ... or am I overlooking
something?
Thanks in advance.

This is a Windows error code. Translated to English, this means that
Windows failed to execute javadoc.exe, probably because it could not
locate it. Make sure that it is in your PATH.

- Eclipse vs NetBeans vs Jbuilder under LinuxHello everyone,
I've tried the above 3 IDEs in the last year and thought I might make some
comments and ask for your thoughts. Just for interest sake and please don't
start a Holy War ;-)
I originally used netBeans for development, but switched over to Jbuilder
because we where doing tomcat/struts development and my boss said it had
better support. I didn't really get to use netBeans struts stuff but it did
seem a bit weak in comparision.
I would have thought Borland would have a great editor, but I find it very
buggy in comparison to netBeans. Some of the things I have had problems
with include the cursor not being moved when you click in the text area
(this tends to screw up click and drag rearrangement of text or do it when
you don't mean too), auto-formatting of code rearranging it until it won't
compile, method parameter popups not always accessable, method parameter
popups not able to show the names of parameters - only the type, and some
others I can't remember right now.
However, the struts support in JBuilder does seem to be better than netBeans
and runs quite well. Over all the IDE also seems a little quicker and I
quite like the way that you can have multiple projects open and flip
between then with ease. netBeans doesn't seem to handle multiple projects
as smoothly as JBuilder.
I also tried Eclipse at home a couple of time in the last 6 months and at
the moment I can't see why many people are using it. On both occasions I
found also sorts of nasty bugs which tended to simple drive me nuts. The
last time time I used it for example, I found that it would not run the
code I had just edited. I.e. if I could load a project, made some changes
and hit the run button, it would run the code without the changes included.
In order to get the changes it, I had to explicitly do a save before each
run. This sounds trivial but can get very annoying, both netBeans and
JBuilder run the code you are editing, not the last saved code.
Eclipse also seemed to have a strange concept of projects. It looked rather
good with being able to see multiple project trees at the same time until
it came to running them. Then it appeared to separate the concept of
running a projects from the projects themselves and I had to effectively
re-setup again. I also found that if I had en error in one project, it
would fail the compile even if I was in another project. So whilst I could
have multiple projects open at a single time, it seemed to have trouble
understanding which projects I was in and what it was to compile. This
resulted in me having to unload/reload projects on a regular basis. I also
remember not being that happy with it's editor either, I can't remember
exactly why right now.
So, I would have to say that at the moment, I would tend to use netBeans for
general development, JBuilder for struts and Eclipse not at all.

- Struts and AA based on a database
Hello:)
I have a question concerning authentification/authorization and
elements visibility on a Web page in Struts. How to manage the
visibility of control elements in a Struts-based application? The
information about users should be stored in a database and not in XML
configuration files. How to use role based or/and function based
authorization system and how to retrieve the rights from a database and
store them in the Principal object? The application is mantained within
Tomcat application server. So, how to do this? Or, being more precise,
is there any open-source library which provides such a functionality or
should I develop everything from scratch? Do you have some examples for
such stuff?
best regards,

- Jars built with JDK 1.3 and JDK 1.4 interoperatingThe Runtime Environment is JRE 1.4. The latest code I have written has
been compiled with JDK 1.4. However it depends on some packages written
and compiled with JDK 1.3. Is there anything to look out for in this
kind of setup or should I have to recompile the older code with 1.4? I
have tested the whole thing and it works, but I wanted some more
information. It is a swing code and I need the JProgressBar's
indeterminate state which is available only in JDK 1.4.
Any update is welcome. If there is any document explaining the above,
that would be perfect. I searched but I was not able to find any
reference.

- Java GSM encoding from micHi
I'm trying to encode a microphone stream into GSM using
org.tritonus.lowlevel.gsm.Encoder but I am receiving just static noise -
I've checked the raw PCM output and it's fine. Is there anything obvious
that's missing here?
Thanks
__________________________
The mic is opened as:
AudioInputStream ais=null;

new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 8000.0f, 16, 1, 2,

);
TargetDataLine mic = (TargetDataLine) AudioSystem.getLine(info_mic);
mic.open();
mic.start();
ais = new AudioInputStream(mic);

And the GSM frame encoder is:
/*------*/
byte [] gsmframe(AudioInputStream ais){
byte [] encd = new byte[33];
try{
byte [] b = new byte[320];
ais.read(b,0,b.length);
DataInputStream di = new DataInputStream(new ByteArrayInputStream(b));
short [] buf = new short[160];
short j=0;

- Re:Correct use of exceptionsWhen we talk about exception, it means that in some situation which we think
that it should works this way, but it isn't. For example, when we write
something to connect to remote SMTP server, we assume that the remote server
should be available but actually it is down... In this case, the exception
happened... So we need the exception handling to show our error message to
user and log the error.
Hope this helps!

- Simple question for those who understand recursion well. Please help.I have a tree represented as a linked list of simple objects
(nodeId/parentId pairs) where the root node is the 1st element in the
list. The other nodes are in somewhat random order. The parentId refers
to the parent node.
I want to convert it into a list where the values are in pre-order.
I.e., I want to get this list as follows: ABCDEFGHIJ (see graph below).
I.e., get the 1st node, put in in the list. If it has children, go
through them one by one, get their child nodes, then put the parent in
the list, then the leftmost first, and go from there. I.e., so that
it's ordered in my linked list like this by (letters represent nodeId):
A
/ \
B J
/ | \
C H I
|
D
/|\
E F G
I created the following recursive method but it does not work
correctly. For example, it places the nodes A then B and then J into
the list first, rather than getting to J after adding all the child
nodes. "isOnTheList" checkes whether the item is already in the list.
"getImmediateChildren" returns the list of immediate child nodes
ordered by nodeId
Note: the empty list is passed to the method and is populated with the
result:
public static void orderTree(List list, List treeList) {
if(treeList == null || treeList.size() == 0)
return;
Node child = null; List children = null;
for(int i = 0; i < treeList.size(); i++) {
node = (Node) treeList.get(i);
// get list of children for this node
children = getImmediateChildren(node, treeList);
// if the node is not yet on the list, add it
if(! isOnTheList(node, list) )
list.add(cat);
// if it has children, recurse to add all other nodes
if(children.size() > 0) {
orderTree(list, children);
}
}
}
Any idea what the problem is?
Thanks.

There's nothing which "requires" you to forward to a JSP; you could
just as easily forward to an action. The hitch here is that the
ActionForm will be populated according to the request parameters if
you just perform a forward. The solution is simply to specify
redirect="true" in the forwarding action so that the request
parameters get lost.
Just be careful in your validate method when using this mechanism:
you're users will be irked if the first time they see a page it
contains all manner of error messages. Since you often provide a
reset button on a form, the smart way to approach the situation is
to hold off generating errors if all form fields are blank (or
have the default value).
If this doesn't make perfect sense then repost and I'll dig up
some sample code. Or contact me off-line.
