  Creates a new JarOutputStream with no manifest.
  
  Parameters:
  
  out - the actual output stream
  
  Throws:
  
  IOException - if an I/O error has occurred
Method Details
- putNextEntry
  
  public void putNextEntry(ZipEntry ze) throws IOException
  
  Begins writing a new JAR file entry and positions the stream to the start of the entry data. This method will also close any previous entry. The default compression method will be used if no compression method was specified for the entry. The current time will be used if the entry has no set modification time.
  
  Overrides:
  
  putNextEntry in class ZipOutputStream
  
  Parameters:
  
  ze - the ZIP/JAR entry to be written
  
  Throws:
  
  ZipException - if a ZIP error has occurred
  
  IOException - if an I/O error has occurred
