- PHP, python, perl, C++ - whatever technology friendly so I will be
free to learn
- reasonably price
I am also in registering my domain anonymously. Any good services?
Any suggestions?

- Requesting re-pack'ing of FrameHi all,
I've implemented my own AWT component which determines a "preferred
size" by itself. This component is added to a Frame, which is at the
center of a BorderLayout in a Frame which gets pack()ed. The frame is
also not resizable, because I must ensure this component always acutally
has its preferred size. This works fine so far.
However, during execution time this preferred size changes; is there a
*generic* way to propagate this message up to the Frame so it re-pack()s?
I do not want to use a succession of getParent() until I reach the Frame
and call pack() on it, as this component might be used in a situation
which does not allow this in the future (maybe an Applet or in an
resizable/unpacked Frame as part of a more complex layout).
Is there any way to achieve this? I.e., propagate to the Frame/layout
that the preferred size has changed and this should be considered anew?
Many thanks in advance,
Daniel

- chaning label sizes during runtimehi all,
I have a minor problem in my application (sorry I can't post any code,
so I'vm only asking for guidance in the general case, not this
specific one).
In my application I have a number of JLabels that gets their texts
changed during runtime. Unfortunatley it seems that they sometimes
become too wide for the panel they are in. The panel has room to grow
though (it is located in a jscrollpane).
I use
label.invalidate();
after each change, and
validateTree();
on the top container after all changes.
This gives me a somewhat strange behavour though.
On first run nothing happens (i.e the label get's cut)
on second run, the panel to the left shrinks a bit and the lables
there get's cut. On the third run all looks nice.
(run means updating of the labels, not a re-run of the application)
So what is the best way to handle this?
Should I invalidate, and revalidate myself? and if so when should that
be done?
All changes to components are executed in the EDT.
regards
Daniel

- Need help with regex pleaseI'm trying to validate a phone number value. I have passed the value
to my constructor as a String type because I would like to catch the
leading zero in the number. I want to iterate through the String

phoneNum. Below is my code attempt which fails:
phoneNum = phoneNum.trim();
Pattern p = Pattern.compile("\\d");
boolean found = p.matcher(phoneNum).lookingAt();
if (!found){

- char array to numeric data types - fastest conversionI know i can convert the char array to a string then to the appropiate
numeric data types (float, double etc) however I'm doing this millions

a string object.

- how to create jar fileHi,
In help we can read:
To create a JAR file from your help files, make the top level help folder
the current folder. The jar command
descends recursively through the different directories and copies all of the
files to the JAR file.
Use the following steps to create a JAR file named my_help.jar from the
hierarchy example above:
C:\> cd ...\help (where "..." is the path above the \help folder) 1.
C:...\help> jar -cvf my_help.jar * 2.
The jar -cvf command copies all the files in the \help folder and in all
folders hierarchically beneath it into
a JAR file named my_help.jar. As the command creates the JAR file, it
reports its progress with output like
My error message:
"jar is not recoginized as an internal or external command, operable program
or
batch file"
please help me

- How to set font attributes in comboboxI could not make head or tail out of sun's tutorial on
combobox renderer. The example given is getting compiled and
running ok, but how to use those things to my program.
relevant lines I have used in my program are given below.
compiler is giving "can't resolve symbol" on setFont line.
and when I am changing that fontname to
normalFont.deriveFont(Font.ITALIC), it is compiling and
running, but the data that was appearing ok previously, is
all appearing blank.
I am moving data in combobox and it is appearing. Just that
its font, size and color is not ok. I want to set font to
some unicode font, size to 18, color to blue.
If possible, I want different fonts, sizes, colors on
different parts of same entry in combobox. something like
set text: (font1, size1, color1) abc (font2, size2, color2) xyz
I have tried <html> as was used on JButtons but that is not
working.
how to do it?
thanks.

- java numerical library recomendationHi,
I'm a relative newcomer to Java and I was wondering if there any good
numerical libraries (on the lines of GSL for C) available? Specifically
I'm looking for linear algebra routines, least squares and minimization
routines. I'm interested mainly in Opensource libraries but I am also
open to commercial libraries.
Thanks,

java-programmer, Is there any basic base for a community website? (J2ee)
Hi
I'm wondering if there is any basic "base" for a community website. With
things like support for user registration, login, individual homepages,
photo albums, sending messages, guestbooks, diaries and so on... And
ofcourse with optimised code (especially the code for the communicating with
the database).
I mean, I know these things have been written before, so it feels a bit
stupid to do it again, like reinventing the wheel.
What I'm looking for is a basic foundation, written in J2ee (Java/jsp), that
is easy to use as a base when making a community that should be able to
handle a large "population" (at least a few thousand simultanous users, and
holefully ten thousands or even houndred thousands at peak hours, in the
future).
Any suggestions?

Now I have read pretty much everything there is to read on their website,
and I still can't figure out exactly what it is. Their description of it is
way to fuzzy for me. I read the tutorial, but it seemed to focus on how a
administrator creates a new user, and then how content is uploaded.
What I'm looking for is more like a bunch of java files, that can work as a
base for a online community. I would like one ore more java-servlets, some
java classes that handle the DB, and some jsp-files that I can modify.
I have already written all this. But I'm sure that I have made many, MANY
misstakes, regarding sequrity and performance. So I would like a small,
simple, fast and sequre foundation to build on. I still want to be in
controll of everything, and not rely on a web interface to build the site.
Anyone?
Regards
/Jimi

Well, I can't really see how I could use netomat and modify it so it would
look and feel exactly the way we want it to. and it seems like they store
everything on their servers. we want to use our own servers, and have
complete controll of everything.

Find out exactly what whatever you want is called, and Google.

- Reading windows event file like event viewer from windows/system32/config/AppEvent.evthi ,any one can help ,me to solve my problem.
i m talking about reading AppEvent.evt SecEvent.evt SysEvent.evt files
which basically resides in C:\WINDOWS\system32\config folder of
windows xp.if we want to open that files and our computer is on n/w
than some services used all three files and i m not able to open that
files manually.if i want to read that files than i have two options
either read by event viewer or copy this file and to another place and
open it in vc++.
i have to read or parse that file by writing a pure java parser
without using any dll bcz that files runs under linux there is another
option to use so(shared object files working as a dll in linux) but i
don't want to depend on dll and so files.
one another way microsoft ;log parser but i m not sure that it
will run on linux or not ,simply i want to write independent java
program using only java based open source api
so plz give me a best approach to read or parse this event files when
they r locked by another applications or services.
this is the link which help u to understand windows event log format
and it has links of sample program written in vc++,c#,asp.net,c+
+,php .
http://www.whitehats.ca/main/members/Malik/malik_eventlogs/malik_eventlogs.html
i follow the php program approach but i got only source name,computer
name,description but not able to parse this things individually and i
also need date,event id,event type.
then i got another code from code project site,which has functionality
to read event logs it is using log4j to read this event files.and
display ti on swing interface but i want only a simple program which
did only reading or parsing event log files.

- Display xml file in JTree: Select information to be shown in node labelHi there,
I have managed to write a small java program that display an xml file
in a JTree. This was achieved by defining a suitable tree model. THe
program works...somehow. The nodes (elements and texts) are correctly
recognized, and the corresponding branches in the JTree can be opened
and closed. However, when I run the program, all the non-leaf nodes
(e. g. the element nodes) are displayed from the start tag to the end
tag including the tag delimiters. Is there any way to control what is
used as a "node label" in a JTree? Of course that could be done by
brute (e.g. by building the JTree from simple strings) but I believe
that this approach will destroy the tree structure of the underlying
xml file.
I have tried for some time to display xml data in a tree view, and a
java solution seemed to be the most "organic" one. So it would be
great if that program to be really made to work properly. Many thanks
for any idea how to achieve this! Piet

- Java Applet Background ColorHi,
I am trying to set the background color of my applet to white but it
keeps coming up gray.Strangely when I open the applet on a local web
page (not live on the web), applet viewer (thru eclipse) or even live
on the web from my own home PC it appears white as expected. But from
every other machine that I access it the background is grey. Even when
i run it thru Eclips on other PCs the background is gray.I have tried
to set the background to white by calling
setBackground(Color.white)
and
setBackground(Color.WHITE)
from the init() method. In the HTML that calls the applet i also set
the <body bgcolor=#FFFF></body> and i do the same for the <HEAD>.
However from every other machine that I access my webpage/applet
except my own home PC the background still appears as gray.
Any ideas?
Thanks

They have no reverse dependencies, do not occur in any build

libxml-commons-resolver1.1-java offers the same functionality. However,
the package is not broken.

I should create and utilize the funcionts of a Java Class from a JSP
page contained in Tomcat.
I Should:
a) define a package containing this class and put it in the CLASSPATH
b) put the Java class in TomCat (folder WEB-INF/lib or WEB-INF/class)
c) a mix of both methods!??! (Classpath AND Tomcat)?!?
Thanks

- SCPJ Certification And Career PathHi All,
I took my "Data Structures And Advanced Programming" coursework at
Berkeley back when they taught this in Java 1.1. Since that time I
have kept active in other languages, but haven't delved deeply into
J2EE, for example. I am very interested in JSP/Servlets and the
forthcoming Java HTML Tag Library. Currently my most proficient
language is PHP, where I am applying all my oo theory but finding the
language lacks some hard edges.
In short, I want to get back into Java development work, ideally on
the web. Is getting a Sun Certified Programmer certification going to
help me in this regard? Do employers look seriously at this? Or should
I try to get my foot back into the door through more hands-on
experience? Maybe work on an open-source project for awhile? My skills
are very transferrable and I can pick up the finer points of Java
again quickly. I'm just interested in the most bang for my buck here.
Thanks for your thoughts.
Regards,
Robert

- Natural logarithm method not recognisedGood day dear members of the comp.lang.java.programmer newsgroup.
I've got the following error message while trying to use the "logl()"
method (natural logarithm function) on my NetBeans IDE
symbol : method logl(double)
location: class org.me.mylib.fluidmechanics.DarcyLaw
wfr = 7.08e-3 * ko_dl * depth_dl * (pr_dl - wbp_dl) / (mu_dl *
bo_dl * ((logl(re_dl/rw_dl) - 0.75)));
1 error
Should I import any special mathematic library from NetBeans?
Many thanks.
Octavio
