e382. creating a manifest for a jar file.txt

这里面包含了一百多个JAVA源文件

A manifest for a JAR file can only be created from an input stream. This example creates a manifest from a file and from a constructed string. The format of a manifest is described in: 
    http://java.sun.com/products/jdk/1.2/docs/guide/jar/manifest.html

    try {
        // Create a manifest from a file
        InputStream fis = new FileInputStream("manifestfile");
        Manifest manifest = new Manifest(fis);
    
    
        // Construct a string version of a manifest
        StringBuffer sbuf = new StringBuffer();
        sbuf.append("Manifest-Version: 1.0\n");
        sbuf.append("\n");
        sbuf.append("Name: javax/swing/JScrollPane.class\n");
        sbuf.append("Java-Bean: True\n");
    
        // Convert the string to a input stream
        InputStream is = new ByteArrayInputStream(sbuf.toString().getBytes("UTF-8"));
    
        // Create the manifest
        manifest = new Manifest(is);
    } catch (IOException e) {
    }

Here's an example of a manifest file:
