Question about Jar file

[HaoZhe Xu]

I created a manifest

StringBuffer mbuf = new StringBuffer();
//store properties in the mbuf
InputStream ist = new ByteArrayInputStream(mbuf.toString().getBytes("UTF-8"));
Manifest manifest = new Manifest(ist);

Then i created a Jar output:

 JarOutputStream jar = new JarOutputStream(new FileOutputStream(file), manifest); 

but i got a jar file that has a META-INF directory and a manifest.mf file in it, but the manifest file includes nothing???

I tried this, using the following properties

mbuf.append("Manifest-Version: 1.0\n");
mbuf.append("Class-Path: someother.jar\n");

Initally, I omitted the "\n" at the end of the Class-Path and it didn't appear in the manifest.mf file, although the Manifest-Version line did appear. Using the code above gave me a manifest.mf file with both lines in it.

Does this give you any help? Could we see your code in full?
