public class JarOutputStream
extends ZipOutputStream
```
The JarOutputStream class is used to write the contents of a JAR file to any output stream. It extends the class java.util.zip.ZipOutputStream with support for writing an optional Manifest entry. The Manifest can be used to specify meta-information about the JAR file and its entries.
Since:
1.2

```
public JarOutputStream(OutputStream out,
                       Manifest man)
                throws IOException
```
    Creates a new JarOutputStream with the specified Manifest. The manifest is written as the first entry to the output stream.
    Parameters:
    out - the actual output stream
    man - the optional Manifest
    Throws:
    IOException - if an I/O error has occurred
  - JarOutputStream
```
public JarOutputStream(OutputStream out)
                throws IOException
```
    Creates a new JarOutputStream with no manifest.
    Parameters:
    out - the actual output stream
    Throws:
    IOException - if an I/O error has occurred
- Method Detail
  - 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
