How do I convert:
class file to jar file using cmd?
class file to exe file?
jar file to exe?
Can I convert exe file to jar file?
Class files to jar files
Usage: jar {ctxu}[vfm0M][jar-file]
[manifest-file] [-C dir] files ...
Options:
-c create new archive
-t list table of contents for archive
-x extract named (or all) files from archive
-u update existing archive
-v generate verbose output on standard output
-f specify archive file name
-m include manifest information from specified manifest file
-0 store only; use no ZIP compression
-M do not create a manifest file for the entries
-i generate index information for the specified jar files
-C change to the specified directory and include the following
file If any file is a directory then it is processed recursively. The manifest file name and the archive file name needs to be specified in the same order the 'm' and 'f' flags are
specified.
Example 1: to archive two class files into an archive called classes.jar:
`jar cvf classes.jar Foo.class Bar.class`
Example 2: use an existing manifest file 'mymanifest' and archive
all the files in the foo/ directory into 'classes.jar':
jar cvfm classes.jar mymanifest -C foo/ .

Convert .class to .exe is discussed in length here
You must have missed this. Please look into Java Archive (JAR) Files Guide.
And surely missed Real's How to for it Make a JAR executable There are multiple wrappers that do this work (converting Jar to exe, platform specific). You just need to search in StackOverflow for Jar exe
To convert (actually, package) .class files into .jar files, you use the jar tool. You can then generate a .exe file from the .jar using tools like Launch4j, JSmooth or several other packages (search the web for "jar exe").
If you are using Netbeans IDE, then creating .exe file from .class file won't take much time. In IDE, create a new project and put your java program in this project. Now follow these steps-
Right click the project and choose properties.
Choose run from left panel and enter the main class(in which main method is defined) in right panel.
Again right click the project and choose add library. Select swing layout extensions. Click add library.
4.Now select clean and build from run menu in your IDE. Make sure that you have already set your this project as main project.
Open the CMD and set the directory to your project. Go to "dist" > and type java -jar jarname.jar.
Your program is running in cmd now.
Open launch4j and provide the information required.
Run and enjoy your application.

Converting exe to a jar file is possible. But involves reverse engineering to discover what is in the exe, extract and do whatever you want with it. In my opinion, is not worth at all.

i have a folder on my desktop named theme.I am new to Linux totally.
So what do I do to create a jar file from this folder?
I found this example but It doesn't work for me.
jar -cvf theme.jar
You are failing to specify the input files for the jar.
Navigate to the theme/ directory using the cd command in Terminal. If you want to include everything in this directory in your jar file, use the following command.
jar cvf theme *
Note that the * character (wildcard) indicates you want to include all files and subdirectories.
See: http://docs.oracle.com/javase/tutorial/deployment/jar/build.html
Jar files are really just zip files, renamed to .jar. Just use any folder zipping tool (such as the zip command).
zip -r theme.jar /path/to/desktop/theme
I have program in Java in path: C:\...\MyProgram.
This program have some dependencies to others *.jar files. I would run it using cmd. So what I do:
in cmd I write cd C:\...\MyProgram\bin and then java -cp C:\...\MyProgram\*;. main.Main. It is working. But now I exported MyProgram to jar file. Could you tell me how can I run this now? So I have file MyProgram.jar with these same dependencies. How run it by using cmd?
Folders and archive files
When classes are stored in a directory (folder), like /java/MyClasses/utility/myapp, then the class path entry points to the directory that contains the first element of the package name. (in this case, /java/MyClasses, since the package name is utility.myapp.)
But when classes are stored in an archive file (a .zip or .jar file) the class path entry is the path to and including the .zip or .jar file. For example, to use a class library that is in a .jar file, the command would look something like this:
% java -classpath /java/MyClasses/myclasses.jar utility.myapp.Cool
Found in http://docs.oracle.com/javase/7/docs/technotes/tools/solaris/classpath.html
You need to add a Class-Path entry to the manifest file (META-INF/manifest.mf) inside the jar:
Class-Path: /C:/.../MyProgram/ .
This assumes that there are dependent classes under C:/.../MyProgram/, not jar files.
You should also add an entry for the Main-class:
Main-Class: main.Main
Then just execute your jar as
java -jar MyProgram.jar
Set the path of JAR file in your classpath and then execute the other JAR file.
To add JAR using eclipse.
Right click on project -> properties
Java Build Path -> Click add external JARs.
This will add JAR to your classpath.
I have some java code written in a text file, now I want to create a jar file to use that file as a library in my android project. So what would be the best way to make a jar file from this point. Please note that I have some code written in a textfile and saved as a .txt. If I rename that file to .java and use this code
jar cf filename.jar file(s)
a jar file is created but when I decompile it in java decompiler it doesnt show the packages and that codes that's why I am unable to use it's methods. What would be the best way to do this? I need help
If you want to use the classes in your library they must be compiled and you have to manually create all the packages subfolders.
So :
1. Make a folder
2. Create each package subfolderds in it (com/foo/bar/xxx)
3. Compile each of your .java files and put them it the correct subfolders
4. Zip your folder and rename it with a .jar extension
But it is hard to do this by code, why don't create it with your IDE ?
Creating a jar File in Windows Command Prompt
Start Command Prompt.
Navigate to the folder that holds your class files:
cd \mywork
Rem -- Set path to include JDK’s bin. For example:
path c:\Program Files\Java\jdk1.5.0_09\bin;%path%
Rem -- Compile your class(es):
javac *.java
Rem -- Create a manifest file:
echo Main-Class: DanceStudio >manifest.txt
Rem -- Create a jar file:
jar cvfm DanceStudio.jar manifest.txt *.class
Rem -- Test your jar file by trying to execute it
Rem -- This will not apply for a library JAR file without any main
java -jar DanceStudio.jar
I have been trying to convert jython scripts to .jar file. I followed,
Distributing my Python scripts as JAR files with Jython?
The link above and also the Jython wiki link shown inside it use a command line script called, "zip". Its like => zip myapp.jar Lib
and so. I am on windows machine, so I couldn't find any script as "zip" on my command line, may be its a Linux script. Help me to do it in windows machine
Second is I have few external .jar's that are used in my jython scripts, for this the above link says to use manifest. But I want to package all external jars into single myapp.jar(for example) file to be running. Just like java -jar myapp.jar, so is there any way to package external jars also?
So please help me resolve this
You can use jar command to add files to .jar archive. Just like:
jar uvf jythonlib.jar Lib
Use jar to see help with options and examples of usage.
As you can see, the code zip -r jythonlib.jar Lib and zip myapp.jar Lib/showobjs.py, just add files to a jar archive. The zip program is a specific tool to do this, but it is not the only one. On windows, I would recommend using 7-zip to create the jar. Rather than zip -r jythonlib.jar Lib, open a new 7-zip window, create a new archive (zip protocol) called jythonlib.jar and add the folder called Lib which resides in $JYHTON_HOME. Then continue with the guide and when you get to zip myapp.jar Lib/showobjs.py, simply drag and drop the file called showobjs.py into the existing 7-zip window. This should add the file to the archive.
I'm not very skilled in writing batch files and/ or java. I have a folder with several .class-Files and folders in it and I want to put them all into a executable .jar-File. I know that there is a tool called "jar - The Java Archive Tool", but that just won't work for me. My folder structure looks like this:
Folder "test"
File (a.class)
Folder "subdirectory"
File (b.class)
I want a executable .jar-File called file.jar. In this .jar should now be the file a.class and the folder subdirectory with the file b.class in it.
I don't get the .jar-Tool to run and the 7zip command line doesn't support .jars (I can't even add files to it). I want this to run from a .bat-File, so I just have to open the batch-file, it creates the .jar and puts the files in it and then closes itself again.
I hope you can help me and get what I mean.
If you have issues in executing jar command, then probably you would need to check if your path has been set correctly. You can verify if the path contains jdk location ( echo %path%) from command prompt. If not you need to update. Also you can verify using Javac -verbose command to see jdk is installed.
Once you have jdk path set, you can try below command to create jar
Jar -cf myapp.jar * --> includes all files including files from sub folders.
If you want to run from batch, you would need to mention path before jar command. Ideal place for path is to configure as environment property.
Create a text file (and call it something useful like manifest.txt). In it, put the line:
Main-Class: a
(which should be called A by convention) and include a hard return at the end.
Then create the jar with:
jar cvfm file.jar manifest.txt *.class
or
jar cvfm c:\somedir\file.jar c:\somedir\mainfest.txt *
You could just put that line in a batch file called createJar.bat and run it if you only want to create files called 'file.jar'
