I want to distribute a command-line application written in Java on Windows.
My application is distributed as a zip file, which has a lib directory entry which has the .jar files needed for invoking my main class. Currently, for Unix environments, I have a shell script which invokes the java command with a CLASSPATH created by appending all files in lib directory.
How do I write a .BAT file with similar functionality? What is the equivalent of find Unix command in Windows world?

Compile Java program using -classpath option:javac -classpath ~/jjava/class -d ~/jjava/class TimeTest. java<cr>--This command tells the javac to compile TimeTest. java and put the resulted bytecodes in ~/jjava/class/.
Use double percent signs ( %% ) to carry out the for command within a batch file. Variables are case sensitive, and they must be represented with an alphabetical value such as %a, %b, or %c. ( <set> ) Required. Specifies one or more files, directories, or text strings, or a range of values on which to run the command.
You want to use the for loop in Batch script
@echo off setLocal EnableDelayedExpansion set CLASSPATH=" for /R ./lib %%a in (*.jar) do ( set CLASSPATH=!CLASSPATH!;%%a ) set CLASSPATH=!CLASSPATH!" echo !CLASSPATH! This really helped me when I was looking for a batch script to iterate through all the files in a directory, it's about deleting files but it's very useful.
One-line batch script to delete empty directories
To be honest, use Jon's answer though, far better if all the files are in one directory, this might help you out at another time though.
