开源工具：jtar

例子主要参考官网：http://code.google.com/p/jtar/

eclipse下结构：

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

import com.ice.tar.TarEntry;
import com.ice.tar.TarOutputStream;


public class TarTest {
	public static void main(String[] args) throws Exception {
		// Output file stream
		FileOutputStream dest;

		dest = new FileOutputStream("c:/test/test.tar");

		// Create a TarOutputStream
		TarOutputStream out = new TarOutputStream(
				new BufferedOutputStream(dest));

		// Files to tar
		File[] filesToTar = new File[2];
		filesToTar[0] = new File("c:/test/1.txt");
		filesToTar[1] = new File("c:/test/2.txt");

		for (File f : filesToTar) {
			out.putNextEntry(new TarEntry(f));
			BufferedInputStream origin = new BufferedInputStream(
					new FileInputStream(f));

			int count;
			byte data[] = new byte[2048];
			while ((count = origin.read(data)) != -1) {
				out.write(data, 0, count);
			}

			out.flush();
			origin.close();
		}

		out.close();
	}
}

 

在本机上创建文件c:/test/1.txt和2.txt文件；

运行以后，则会在该目录下生成test.jar文件；

固然还有一些问题须要考虑：如解压、压缩过程的乱码等；
