[Help] Compile and running a java which uses libraries in linux

I have a java program which has all it's *.java files in the src directory. it uses libraries (e.g. activemq-core-5.1.0.1.jar and commons-logging.jar) stored in a folder called libs which is in the directory level as the src folder.
how do i compile this program in linux and convert it to a jar file?
once compiled how do i do run it? will simply running the jar file i just created be sufficient?

I don't know what your application does but the basic way of compiling classes in Linux is
javac -classpath ALL_DEPENDENCY_LIBS PATH_TO_SRC_FOLDERAnd in case of Linux the dependency files ought to be separated by : and not ;
I would suggest you have a look at ant or maven for building your project,
To start might be difficult, but it will surely payoff as you build large projects once you know how they work!

Hello,
1. The .form file was used by Netbean's GUI builder to create the .java and is not needed for compilation.
2..../src # javac -classpath "..." mytool/*.java
I guess the package mytool was not coped with.
Alternatively it is worth to use the ant build tool also used by Netbeans.
Then you can make a jar from the class files, indicate in the manifest.mf file:
1. the main class
2. the library jars

How to compile and run a .java file from another java program

hello,
can any one tell me how to compile and run a *.java* file from another java program which is not in same directory?

Well a smarter way of implementing this is by using a solution provided by Java Itself.
If you are using J2SE 6.0+ there is an in built solution provided along with JDK itself and inorder to go ahead with solution the below are set of API which you;d be using it for compiling Java Programs (Files)
http://java.sun.com/javase/6/docs/api/javax/tools/package-summary.html
How do i do that ??
Check out the below articles which would help you of how to do that

Now once we are done with compilation.In order to run a Specific class all you ought to do is create an object and its specific methods of a specified class included in the CLASSPATH which you can manage it easily by usage little bit reflections.
Hope that might help :)

How can I compile and run other java classes from within an application?

Hello there everyone! I really hope that someone can help me. I am writing a program that must be able to compile and run other java classes that are in different files, much like development environments like Kawa or Forte allow you to do.
There has to be a way of doing this ( I hope!! ), but i can't seem to find it!!
I have tried using this command to compile:
Runtime.getRuntime().exec ("c:\\programs\\javac className.java");
...and this one to run:
Runtime.getRuntime().exec ("c:\\programs\\java className");
...but neither works!!! I can compile and run classes that are in the same file as my application, but I can't get it to work at all for files in different directories or files.
PLEASE, PLEASE, PLEASE help me - i've run out of ideas, and i need this to be working in 3 days!!!
Thank you very much for any help anyone can give me, I really appreciate it!! Thanks again!!
Adrian ( ...in distress!! )

public class JavaCompiler{
   public static void main(String[] args)throws Exception{ //sorry bout the laziness
      if(args == null || args.length != 1){
         System.out.println("Usage: java JavaCompiler MyClass.java");
         System.exit(0);
      String className = args[0];
      Runtime rt = Runtime.getRuntime();
      Process p = rt.exec("javac " + className); //consider setting cpath for this
      p.waitFor();
      //now try to run after it is done.
      p = rt.exec("java " + className.substring(0, (className.length() - ".java".length()));
      p.waitFor();
      //do some other stuff
}This should get you going. You may consider looking into the System.getProperty() method in order to determine the type of OS it is running on in order to findo out what command to run. I know that the sun tool listed above is nice, but by my understanding the sun tools provided are not guaranteed to stay the same. I'm no expert on this matter, but that is one of the reasons there is no API documentation for those tools. Also, I don't believe those tools come packaged with the JRE. (Of course if you are making an IDE it will be expected that the user has an sdk installed. Good luck with figuring this thing out.

How to compile and run a java program?

I am getting this error message, what to do?
Exception in thread "main" java.lang.NoClassDefFoundError:
Thanks for you help.
Ajay

Hello,
I believe that this error is caused because when you
compile and run a java program, you have to use the
same name that is next to public class. For example,
the program name is next to the word public class.
For example, if a program began like this:
public class Concat
then the name of the program in this case is Concat
and when you compile it you type: javac Concat.java
when you run it type: java Concat
depending on the name of your program.and depending on whether the class is in a package. And depending on what directory you are currently in.
Also depending on if you set your class path you might
have to type the above like this: jdk1.2.1\bin\javac
Concat.java to compile, and to run you would have to
type jdk1.2.1\bin\java Concat where you would replace
Concat with the name of your program and replace
jdk1.2.1 with the name of your version of java, that
is again if you do not have your classpath set. Hope
this helps.Your examples have nothing to do with whether the CLASSPATH is set--only with whether the PATH is set. And, it may not be jdkXXX\bin. The path to the JDK (in this case, to javac and java executables) could be anything. Classpath should be set on the command line. The OP probably did NOT set a classpath on the command line (preferred), or in the environment variables.
Also, make sure you did not forget to put:
public static void main(String[ ] args)
on the line underneath the line where it says "public
class Concat" where Concat is the name of your
program. Again, I hope this helps.Irrelevant (with the info we have from the OP so far). The error says that the JVM can't even find the class--not that the class doesn't have a main. The "main" referred to in the error message is within the JVM itself.
OP: Did you fix your problem? If not, what directory are your files in? Are they in a package? What command are you typing to get that error? That is, please tell us your entire command line.

Compile and run java programs using batch file

i am using eclipse to run my java programs.How to compile and run those programs using a batch file?

a) just write a batch file, and add it to the project. When you want to run it, go to a command window and invoke it. (There is probably also a way to invoke it from Eclipse)
b) if the project is complicated, take a look at ant. Eclispe knows about ant files.

How to compile and run java files on a mac using command line?

can someone tell me or link me to some article on how to compile and run java files from command line on a mac? I have mac OS X leopard

What do you mean by "where to put them" ? What do you want to put anywhere ?
Have you read Peter's comment in brackets ? Perhaps you have a classpath problem ?

Java compile and run time questions

Hello, I have two generic question about java compile and run:
1. When I used javac to compile my project, it complained some classes can't be found. I added the jar file which contains these needed classes to the jre/lib/ext/ directory. The compiler no longer complains. But I'm confused. I thought the jar files in jre/lib/ext/ only used for java run time, not the compile time. Can someone help me to explain this?
2. If I need certain user defined jar file in the classpath to compile my application, does that imply that I have to have that jar file if I want to run my project?
Thanks in advance.

1. lib/ext is used for generally finding classes, it doesn't matter whether you are compiling or running.
2. Yes, you will.

How to compile and run package programs in Java

Hi,
I want to know how to compile and run the package programs in Java using -d. instead of creating the package folder manually.

I want to compile this without creating the folder ' Test ' manually. that is if we use -d with javac the Test folder will be created automatically. I need the format of -d
could anyone please help me.

Java compilation and running within jsp page

hi,
i need of a jsp page that has a textarea in which the java coding are entered and this coding is compiled and executed. The execution result is printed.
Please guide me.

I don't think you can invoke java compiler or run time environment at client side (browser). Even if you use applet, i think you will not be able to do it at client side. Moreover, though java virtual machine will be available in your target user's browser, but you should not expect a java compiler in users machine.
I have seen exam sites where they have added java code compilation and execution ability. To achieve this you can do:
1. In your JSP page use text area where user can edit java code.
2. Provide two buttons - 'Compile' and 'Run'.
3. On click of 'Compile' send the code to server side. In server machine create a file in a temporary location in disk and save the code content received from client.
4. Invoke 'javac' command (as a separate process) to compile the java class created in step 3. This process will give you error/output back which you can send back to user.
5. In case of 'Run' you must first invoke above mentioned 'Compile' service and then another service ('Run') to actually run you java class. You can build 'Run' service in similar way.
Here you challenge would be managing multiple client requests (to compile and run java class) at the same time.

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.
thanks

To 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

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.
