Linux

i wish to run java files on inux but while downloading it into linux there is no problem but when i r try to execute a java file it says javac not found. help pleas

Which distribution are you running?
Did you install the file before trying to execute it?
Downloading is just that, you copy it from one machine to another, you need to install it to make it available for using.

i have installed java on my machine but when i check the version it givex=s a lot of error messages

Please give us more details as to the exact error messages you are getting, the command you used to invoke java/javac.

Also, what you are trying to do actually? Executing a compiled java program does not need javac. java is sufficient. javac is for compiling bytecode.

So, what is your command used to execute your java file?

On executeing this:-
/usr/java/jdk1.3.1_03/bin/java -version
/usr/java/jdk1.3.1_03/bin/i386/native_threads/java: error while loading shared libraries: libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory

Java file
public class a{
public static void main(String[] args){
System.out.println("Hello World");
}
}
javac a.java
bash: javac: command not found

Try

/usr/java/jdk1.3.1_03/bin/javac a.java

for compiling.

I am not sure about the shared library problem you are having. I have installed JDK1.4.x on many Linux systems without problems. Maybe you can try JDK 1.4 as well. As the directory structure the error message displays differs from the Sun Microsystems one (I can't find any bin/i386 dir in my installation), probably your version is not an official one. Try downloading from java.sun.com for official builds.
