Execute java program on UNIX

I have no experience on Unix and I now need to try to execute my java program on UNIX server to which I connect using telnet. I have copy my source file to the server and I could run the javac command to compile my source code.
In the current directory, I just execute "javac mySource.java"
And I got my .class file on the same directory. But when I tried to execute "java mySource", I got NoClassDefFoundError. I think it has something to do with classpath. But I just don't know how to do it in UNIX. Please someone assist me. Thanks.

Or setenv CLASSPATH $CLASSPATH:/your/classpath/here if you are running csh.

You can execute any jar or class file with cron. If you are using a jar you might use something like java -jar /usr/bin/myapp.jar .
I use Linux, this is my area of expertise.
Here is an online guide "for complete newbies" on how to set up cron.

How to execute java programs in xcode

I cannot execute Java program in XCode for Mountain Lion 10.8.2. Please help me how to execute a Java program.

Do you have a particular error or message or diagnostic or issue, or something that's particularly wrong with Xcode? If installed, Java does work, and Java applications can be invoked.
Background: Java was deprecated from OS X a while back, and Java itself was removed from the default OS X 10.8 installation.
Given that Java is now an add-on for OS X, you'll want to check with Oracle — the owner of Java — for OS X kits and tools.
I don't know off-hand if Xcode still particularly supports Java (it was pretty weak, when last I checked), but I'd expect you'll be using makefiles for the work, and I'd also suspect that whatever Java support remains in Xcode will probably be going away in some future version of Xcode. (If support hasn't already disappeared. You may be using bash build scripts and makefiles to deal with Java now, or going forward.)
If you don't have access to the Apple developer forums and the discussions of tools available there, then the archives of the Apple Java-Dev mailing list can be a good spot to look for existing discussions, and to post questions related to Java development on OS X.
As for IDEs other than Xcode, Eclipse or NetBeans or IntelliJ IDEA, and BlueJ all run on OS X, and any of these would probably be a better long-term choices for Java development on OS X.

Executing java program in oracle

Good day everyone!
I created a small java program.
import javax.swing.JOptionPane;
public class LogOn {
public static void main (String [] args) {}
public static void ShowMessage(){
JOptionPane.showConfirmDialog(null, "Hello", "Info", JOptionPane.PLAIN_MESSAGE);
I compiled the code using javac and loaded into oracle using "loadjava -u scott/tiger Logon
Then I created a procedure,
create or replace procedure l_b
as language java
name 'LogOn.showMessage()';
then I executed the procedure
SQL> execute l_b;
it's just say
ERROR at line 1:
ORA-03113: end-of-file on communication channel
Any idea why its doing that?
Thanks for the time

What is the "warning banner" attempting to communicate? And where did this requirement come from-- presumably users are not seeing a banner when they log in today.
Realistically, you are not going to be able to cause arbitrary client applications to display something, you are going to have to configure each client application separately, which seems like a huge investment of time for very marginal benefits assuming that government agencies have a decent number of client machines and a decent variety of client applications. The glogin.sql file will work for SQL*Plus (assuming very recent versions or that no one uses the "connect" command to connect to a different database), but I believe you are looking for something that works across client applications, which probably doesn't exist.

Creating an executable java program

hello every body
i have finished my java program
and i want to ask if there is some software that create a .exe of your project or make your projecte installable.
for the moment i use javaexe but it's not really good
do someone have an idea.

That's the question most people ask.Actually this
proccess is againts the goal of java for being a
platform independent programing lang,That's an urban legend I haven't heard in a while -:)
How can the generation of a native executable out of a Java source be against the goals of Java? Has the source code been contaminated in any way in the process? Is it now less portable than before? The native executable itself isn't portable of course but that's kind of the point of producing one, and it doesn't restrict the portability of the program itself.

Shell script to execute java program

Hi there,
In my script to execute my Java program, I have assigned a variable as follows:
PROGRAM_ROOT = "C:/program"
A jar file that my program needs is located in C:/program/build. ie. it is located in "PROGRAM_ROOT/build".
In my script I have a property set as follows:
-Dprogram.build="$PROGRAM_ROOT/build"
When I execute the script using cygwin, the above line gets converted to the following:
-Dprogram.build="$PROGRAM_ROOT
/build"
i.e. the concatenation of "PROGRAM_ROOT" and "build" results in PROGRAM_ROOT<carriage_return>\build.
Is there a way to use PROGRAM_ROOT and concatenate "/build" to it?

You'd have to build your own client/server implementation or use a remote messaging framework (like RMI) to help you with this if you wanted to do it in pure Java.
It would be easier to just kick off some other installed process to send the message, e.g. install cygwin and pipe the command to start the shell and run the script through ssh. If you wrote a Java program to kick this off, it would only be a couple lines of code, and not really necessary.
It's not ideal to try to do remote command administration just using Java.

Shell script for executing java program

i want to write a shell script which will export the classpath and compile & run the java program.
any references from where i can get that?

Try typing "man sh" at the command prompt.
Ultimately it'll end up looking a lot like this:
#!/bin/sh
CLASSPATH=/path/to/a.jar:/path/to/anther.jar
JAVA_HOME=/path/to/where/you/installed/java
$JAVA_HOME/bin/java your.classes.package.YourClass

Making batch files to execute java programs in windows

In my comp sci class, i found a folder with a batch file, an application file, and all class files necessary to run the program.
how do i take my java program and make a batch file to run it (in dos) like that program in my comp sci class?

Okay, here are your steps for running a java program from a batch file:
1) Open Notepad
2) type the following:
set JAVA_HOME=C:\j2sdk1.4.0_03 // specify the path where your jdk is
set path=%JAVA_HOME%\bin;.
javac {-classpath .;one.jar;two.jar} YourProgramName.java
java {-classpath .;one.jar;two.jar} YourProgramName
The stuffs inside {} is not necessary if your program doesnt use any .jar files.
3) Save the notepad as mybatch.bat in the directory where your Java program is located.
4) In the DOS prompt, go to the directory where you have .java and .bat files
(use 'cd' command)
5) Now, type mybatch.bat and press ENTER.
Thatz it. Your program runs like a charm now!!!
(provided the compiler is pleased with ur code :)

Execute java programs automatically when system is connected to internet

Good Day friends...
Iam beginner in java. Please goes through the Question and please answer.
I need to start my java programs automatically when system(windows operating-xp/7) is connected to the internet.
Thanks in Advance,
Shackir

A. You might want to learn about Windows Services. Try searching for it on the web
B. There is no way to programmatic detect if/when the local computer is connected to the internet, at least not in Java. The best you could do would be to create a timer and to periodically try to make your connection

How to execute Java program in Solaris 8 (Intel Platform).

Hello All,
I have installed Solaris 8 on my Intel based PC. JDk 1.1 and JDK 1.2 is installed by default. When I compile any Java applet or Application, it successfull complies but when I try run that applet or application (java Appletname or applicationname), It gives the error message .... File not found...Check whether file exist in the directory or not.
Can someone tell me the reason of this error and how to correct it. Where to set the CLASSPATh etc. under Solaris 8 for successful compilation and run of programs. I do not have any problem under Windows/2000.
Thanks in advance,
Amoid

Hello All,
I have installed Solaris 8 on my Intel based PC. JDk
1.1 and JDK 1.2 is installed by default. When I
compile any Java applet or Application, it successfull
compliesI will assume that you executed this command:
#javac <java source code filename>.java
In order to find out which version of the javac you are using to compile the program, execute the following:
#/usr/bin/which javac
The output will tell the exact path to the javac binary file.
but when I try run that applet or application
(java Appletname or applicationname), It gives the
error message .... File not found...Check whether file
exist in the directory or not.You probably have not set the current directory to your environment variable PATH for the Unix shell that you are using.
You can do the following:
#java ./<standalone application or applet name>
Can someone tell me the reason of this error and how
to correct it. Where to set the CLASSPATh etc. under
Solaris 8 for successful compilation and run of
programs.In the shell environment settings file. Which Unix shell are you using? Bourne, Korn or C?
I do not have any problem under Windows/2000.
Thanks in advance,
AmoidHTH.
