I’m currently using to compile a Java application, create a Jar file to distribute the application, and finally run the application. I ended up creating these scripts because of configuration problems on my Windows PC, but I thought they might be useful samples for others.
As you’ll see the mostly correct problems with my
CLASSPATH configurations. I should use an Ant build script for this, but I’m too lazy today. I’m also overriding my Java compiler settings on this PC, as I have several Java versions installed on this system.
Here’s the first script I named
1compile.bat that I use to compile my Java program:
set JAVA_HOME=C:jdk1.5.0_06 set PATH=C:Windows;C:WindowsSystem32;C:jdk1.5.0_06bin set CLASSPATH= javac -cp ".;forms-1.0.7.jar" com/devdaily/xylocator/XYLocator.java
Here’s the second script I named
2createJar.bat that I use to create a jar file that I distribute with my Java program:
set JAVA_HOME=C:jdk1.5.0_06 set PATH=C:Windows;C:WindowsSystem32;C:jdk1.5.0_06bin set CLASSPATH= jar cfm xylocator.jar Manifest.txt com/devdaily/xylocator/*.class
That command also requires a file named
Manifest.txt, which looks like this:
Main-Class: com.devdaily.xylocator.XYLocator Class-Path: forms-1.0.7.jar
The first line in the manifest file tells the JVM where to find the
main method to run my program, and the second line helps configure the
CLASSPATH, which is required because this is a Java Swing application that uses the JGoodies FormLayout.
That script creates a jar file (with the manifest included) so I can just use the
java -jar command to run my program. I include that command in a batch file I named
3runJar.bat that looks like this:
set JAVA_HOME=C:jdk1.5.0_06 set PATH=C:jdk1.5.0_06bin;C:Windows;C:WindowsSystem32 set CLASSPATH= java -jar xylocator.jar
