FirstGUI.java:7: Package java.swing not found in import.

Hi,
I am currently taking JAVA at UGA and am trying to learn the GUI part on my own, since our professor is not going to cover this. This is the first error I get when I compile the program. Any help is greatly appreciated...
Thanks,
Joe
Below is the program...

The error is below...

I don't think the actual error is on line 39, I looked in the book that has the code and line 39 is typed just as it is shown in the book.

Build error :package com.sun.javadoc does not exist

Question from a Turing machine expert who is new to Java.
Trying to run a sample program from Richardson's book "Java JDK 5 Edition" Chapter 1.
In Netbeans 5.5 receive build error :package com.sun.javadoc does not exist
for "import com.sun.javadoc.*;"
Believe missing classes are in tools.jar in C:\Sun\SDKee5SDK\jdk\lib
How do I define this to Netbeans and/or JDK?
Using java_ee_sdk-5_01
and netbeans-5_5-windows downloads.
Platform is XP.
Netbeans has been updated to date.
Appreciate.

Jdk1.3.1 'com.sun.java.swing does not exist'???

Thats what the compiler tells me, though it finds javac with no problem in the
jdk1.3.1 lib directory. Any clue to what I'm missing here? Thanks nt

Swing used to be in the com.sun.java.swing package in the very earliest releases, but now it is in the javax.swing package.

I have seen this error when I'm executing inside one of the (j2ee sun reference implementation) server containers (either web or ejb). I believe its caused by "something" having previously loaded the "sax 1 driver class". In my case, I think the container or server is loading the sax parser from a jar that contains a sax 1 version. If you can, ensure that nothing is loading the sax 1 parser from another jar on your system. Verify that you are loading the sax parser from a jar containing the latest version so that you get the sax 2 compliant parser. Good luck!

Package javax.swing not found in import!

I recently installed JDK 1.3.1_02 on WinNT4.0 and I cannot compile javax
packages without getting the following error:
Package javax.swing not found in import
I've tried every combination of modifying the CLASSPATH system variable
I can think of. I have no problem compiling java packages but not
javax packages. I followed the installation instructions to the letter.
What am I missing? Surely someone is running the same version of
the JDK I am on WinNT 4.0.

Thanks again!!! I had an older version of javac running on my system any time I ran
outside of the bin where the latest javac was installed. I removed the older version
of the jdk and now I can compile from any directory. I really appreciate the help,
I was wracking my brain.
By the way, -version is not a valid flag for javac.exe, although it is for java.exe.
signed,
grateful in cyberspace

Package org.apache.axis.message not found in import.

Can anybody help!

I've put a lot og jar files in the bpel-inf/lib but it looks as if they are not in the class path when I need them. The result is a ClassNotFoundException? Do I have to specify anything else? I've put a class in the bpel-inf/classes and it looks to me as if it is found by the BPM.

Com.sun.java.swing.*; ??

I have notice these class references in a couple of sample programs.
Do these come with every installation of the jre. I have 1.4 install
and when i reference these library..I am told they don't exist..
What are they ??
Where do they come from ??
How do I get them running in my apps.

Anything in the
sun.*
and
com.sun.*
should not be used directly by you (unless the API's say so), yes the L&F's live in this name space, as does the native bits of Java and the basic implementations of stuff you can only get at via factorys but you still should not use them (unless you are going via the factory, and then you should never rely on it being the same between JREs).

Deployment problem on WLS8.1sp3: com.sun.javac.Main not found

Hi,
I have a curious problem, after adding some simple (logging) code to an Session Bean, the EAR file will not deploy. I get the message below concerning compilation problems. If however I restore the Session Bean to the previous state, and having build a new EAR file, the erro persists. What is this strange behaviour, has this to do with weblogic settings for the EAR file of whatever ?
NB I also have tried to include the tool.lib jar in the projekt but that doesn't solve the problem.
Any help would be appreciated,

Com.sun.java.swing package not found

All my other programs compile fine if they're not using that package

yea...wrong import....
use
import javax.swing.*;notice the X

Package com.sun.j3d does not exist (Linux - Fedora Core 6 - jdk 5.0)

Here's the thing.
I realize it's probably a classpath issue, but I don't know where to put the libraries. Compiling non-3d code works fine, which leads me to believe that running the j3d installer in the right place ought to put the libraries in the right place and let me use them. Clearly this is not the case.
Now I've tried to fiddle with the classpath, specifically I've put this into my .bash_profile:
CLASSPATH=.:$CLASSPATH:$HOME/Libraries/ext:$HOME/Libraries/i386
export CLASSPATH
And stored the jars in a libraries folder on my home directory
Odd thing: echo $CLASSPATH sends out empty, like CLASSPATH isn't even defined. How do I fix that? And if that's true, why is the regular javac working?

Package com.sun.j3d does not exist (Linux - Fedora Core 6)

I posted this on the 3d forums also, but it really has nothing to do with 3d but the classpath (I assume) so posting it here might work better.

Use
. .bash_profile
P.S. Where did you find the information to use
.bash_profile. I would expect you to set the
classpath in .bashrc, .profile or, to allow all to
get the same environment, in /etc/bashrc .I tried . .bash_profile and got this answer:
bash: CLASSPATH: command not foundAnd I don't recall how I decided to use .bash_profile, but .profile doesn't exist and I don't understand the syntax in .bashrc and it frightens me.

Com.sun.java package

Hi,
What is the different between javax.swing and com.sun.java.swing package ? Are they the same ?
Where can I download com.sun.java.swing package ?
Regards,
Lim Boon Sun

The official Sun statement is that one should only use the classes listed in the APIs, i.e. javax.swing.*. Classes in packages such as com.sun.* contain version dependent implementations and are subject to change without notice. So, if you use them in your programs, it is very likely that your programs will not run under future (and previous) versions of the JRE.
So, just like the other fellow said, STICK TO THE javax.swing.* packages !
