Can't run java or javac from dos prompt

I just installed j2sdk1.4.1 on win98SE. I have a problem where I can't seem to be able to compile or run an application from the dos prompt. I can do both in Visualage for Java or in JGrasp but not at the DOS Prompt. I have set the PATH statement to PATH=c:\j2dsk1.4.1\bin and the classpath=c:\j2sdk1.4.1\lib. The following is a typical error message:
javac RunApplet.java
RunApplet.java:8: cannot resolve symbol
symbol : class MyApplet
location: class RunApplet
MyApplet myApplet = new MyApplet():
RunApplet..java:8: cannot resolve symbol
symbol : class MyApplet
location: class RunApplet
MyApplet myApplet = new MyApplet()
2 errors
java RunApplet.class
Exception in thread "main" java.lang.NoClassDefFoundError: RunApplet/class
It seems like the system can't locate the class files?
Also is there away to use more than the standard 8.3 charecter set in the DOS prompt window?
TIA

javac RunApplet.java
RunApplet.java:8: cannot resolve symbol
symbol : class MyApplet
location: class RunApplet
MyApplet myApplet = new MyApplet():
RunApplet..java:8: cannot resolve symbol
symbol : class MyApplet
location: class RunApplet
MyApplet myApplet = new MyApplet()
2 errorsMost likely a Classpath problem. I suggest changing your classpath to:
classpath=.;c:\j2sdk1.4.1\lib
java RunApplet.class
Exception in thread "main"
java.lang.NoClassDefFoundError: RunApplet/class2 problems. As ChuckBing says, the command needs to be "java RunApplet" with no .class. The argument to the java command is the class name, not a file name. The second problem - if you do not have a successful compilation, there won't be any .class file to run.

HOW to run a batch file in DOS 6.22???

I have written a batch file that runs fine under Windows Command Prompt, but I would like to be able to run it after POST in DOS. I have copied my code to AUTOEXEC.BAT file which gets executed automatically; however it comes up with syntax errors
once it reaches the call command and the rest.
echo. This script is counting the # of POSTs.
echo. The POST # value is saved in TEST.txt.
echo.
call:myPOSTTest
for /f "tokens=* delims=" %%x in (A:\TEST.txt) do echo POST# %%x
echo. &pause&goto:eof
::-- Function section starts below here
:myPOSTTest - here starts my function identified by its label
set var=0
if EXIST A:\TEST.txt (
for /f %%x in (A:\TEST.txt) do (set /a var=%%x+1)
echo %var% >> A:\TEST.txt
goto END
:END
Thank You

Call is used to execute another batch file external to the one your in, you can only call a label if the command extensions are enabled.

Since you are not passing any parameters into :myPOSTTest you might just be able to use GOTO instead.

Error when running mortgage calc program from DOS prompt

I have a GUI Mortgage Calculator program. It probably isn't the most efficient use of code, but it gets the job done. I am running java SDK 1.6.0_06. This is a class assignment. We are to compile the code and post the .class file for our team members to run. I am trying to get the .class file to run after I compile it with javac. I used jCreator LE to create it... it compiles and runs there just fine. The program will compile at the DOS prompt, but will not run properly. The following is the error I get (any help would be appreciated):

The class is not in your classpath. Likely you blew away your classpath with some silly environment variable.
If you are in the directory where your class file is then execute
java -cp . manchorMortgage3and it will work. (Note the -cp . which tells java to include the current directory in the runtime classpath)

Run Swing application without opening DOS prompt window

is it possible to run a Swing application without opening a command interface window in MS Windows?
thanks

Don't know if you mean that, but if you try to call javaw.exe instead of java.exe there pops no prompt up.

How do you get to the DOS prompt so that you can type in the info to help get into itunes store??? One post said search cmd, right click, run as administrator but where is the search cmd??

Have been struggling for days trying to get into the itunes store. Have contacted support with no help. I have been reading how some have typed something into a DOS prompt and have resolved their issues. One stated to "search cmd, right click, and run as admininstrator" but where is this? There was also a post about typing something into the DOS prompt....how do I get to this? Can someone please help??? SOOOOO FRUSTRATING. Thanks much...Carrie (Mike's wife:))

One stated to "search cmd, right click, and run as admininstrator" but where is this?
In the search field in your Vista start menu, type cmd
Next, right-click on the cmd that comes up and select "Run as administrator".

what you willdo is this,
at the top of your code type the line.

//for event type the next line..
import javax.swing.event.*;
import java.awt.event.*;
I think this should solve your problem.
