Simply Running Java Programs
When using the command java classname on MS_DOS I get the reply
"Exception in thread "main" java.lang.NoClassDefFoundError: classname. Even though it is able to compile the .java file. I am running java 1.4 on Windows ME. After investigation I have also found that the java 1.3.01 oldjava command works fine. If anyone knows how to fix this that would be a great help as it is currently driving me up the wall!
Cheers
Look like you didn't spell your package/classname right.
use the full name: java <complete package>.<classname>
thus as an example:
java my.package.MyClass
Note, that it is all case sensitive.

Running java program at windows startup
I need to run java program at startup and then it will continue to run in its own thread.
Any body having idea how to do that programmatically?
ZeeshanThis is one option but this is not feasible in my scenario as this application will be running over a network which involves hundreds of computer so is there any way to do it programatically?
I mean if I can load java class file through an exe file then I can load my class file in the startup using C++.
Any Suggestions.
thanks for the help

Can't run java program with GUI
My computer can run java program properly.

How to Set up the variables and others to compile and Run Java Programs
Hello,
I have just downloaded the jdk1.6.0_07 and jre1.6.0_07 and installed it in C:\Program files\Java in my Windows XP ,So please tell me how to sett up the enviroment variables etc to compile and run Java Programs from Command Prompt.
thanksTo set the PATH permanently, add the full path of the jdk1.6.0_<version>\bin directory to the PATH variable. Typically this full path looks something like C:\Program Files\Java\jdk1.6.0_<version>\bin. Set the PATH as follows on Microsoft Windows:
1. Click Start > Control Panel > System on Windows XP or Start > Settings > Control Panel > System on Windows 2000.
2. Click Advanced > Environment Variables.
3. Add the location of bin folder of JDK installation for PATH in User Variables and System Variables. A typical value for PATH is:
C:\Program Files\Java\jdk1.6.0_<version>\bin -

How to run java program from website?
Hello
I'd like to know how to run java program from my web page.
I'd like to push some button in this web page so java program that would be on my server
would pop-up. Can it be done automaticaly upon running this web site? (without any buttons - I just enter website and program pops up).
CheersI rather thought about RMI. But I could try servlets. So how it would look like?.
I would make http request in browser (enter address) and program would show up in its window?. And I would not have to change anything in my program?. This program would run then on both boxes?. One remotely and one not?.
But I would have to learn some basics, I've never worked with servlets. Could you suggest some good sites about it?. With ready examples so I could tweak them to my purpose.

Compile and run java programs in different directroy
Hi,
I often encounter many problems when I run java programs in the different directories. Like
javac -d dir_name a.java
java -cp dir_name a
Something wired often happens, such as, there is not a.java file in some directory, but javac -d dir_name a.java can still work or "java -cp dir_name a" often doesn't work. Moreover, file_name.jar is also a tough problem and solving compiling problems is often time-consuming.
So I hope to read something about how to compile and run java programs in different directory properly.
Could you pleae give me a detailed description for that or recommend a book or website?
Thanks a lot.Can you post a small amount of code that does not work, including the directory structure, and the error messages? Some one here can likely explain the problem.

I want to run java program on windows environment as background process
Hi all
I want to run java program on windows environment as background processSo command prompt return after executing java command and program on background In Linux we can do this easily �but I do not how to do this in windows
for example look this programe
import java.io.*;
import java.util.*;
public class TestClass {
class ravi extends Thread{
public void run(){
try {
String target_file = "ravind.txt";
File targetfile = new File(target_file);
PrintWriter writer = new PrintWriter(new FileWriter(targetfile)) ;
for (int i =0 ; i < 100 ;i++ ){
Thread.sleep(10000);
writer.println(" ravindra shukla ");
} catch (Exception e) {
e.printStackTrace();
public static void main(String[] args) {
TestClass test1 = new TestClass();
TestClass.ravi r1 = test1.new ravi();
r1.start();
System.out.println(" return from main ");
first i compile this
javac TestClass.java
then i run this by using this command
java TestClass
but becouse i put sleep on threads run function so it takes to much time to get return on command promt .... i want to run this programe as background process so command promt return as soon as i execute java commandThanks dude
This solution �start java TestClass� works fine �. But it does not solve my problem
It opens another black window and that black window persist till the life time of my program
Is it possible application run on complete background without opening another black window �as in Linux -
Can't Run Java Programs -- java.lang.NoClassDefFoundError Error
I am running 10.4.11. For some reason I can no longer run Java programs. (I could in the past)
For example. I create a simple Hello World program as follows and save it as Hello.java:
class HelloWorld
public static void main (String args[])
System.out.println("Hello, world!");
Then I compile it:
Javac Hello.java
Then I try to run it:
java Hello
But I get this error:
Exception in thread "main" java.lang.NoClassDefFoundError: Hello
I think it must be a CLASSPATH problem but normally you do not need to worry about ClassPATH. Apple sets it up for you out of the box.
What is wrong?I totally forgot that the class name should be the same as the filename.
After I renamed the file to HelloWorld.java and recompiled, I could run "java HelloWorld"

Hey,
I left my office yesterday evening leaving my macbook on
while it was running a java program that it's supposed to requires between 2 and 3 hrs.
This morning not only the program was still running (hard to believe it takes more than 12 hrs!)
but when I typed in the shell the 'ps -all' command
it says the program has been running for around 30 mins, and now it's still running!
Is it possible that with certain settings the mac stops its processes after a while?
What should I check?
Thanks for helping, I'm actually a newbie in the mac world:)
