JarOutputStream
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.

Public constructors
JarOutputStream
JarOutputStream (OutputStream out,
Manifest man)
Creates a new JarOutputStream with the specified
Manifest. The manifest is written as the first
entry to the output stream.
| Parameters |
|---|
out |
OutputStream:
the actual output stream |
man |
Manifest:
the optional Manifest |
JarOutputStream
JarOutputStream (OutputStream out)
Creates a new JarOutputStream with no manifest.
| Parameters |
|---|
out |
OutputStream:
the actual output stream |
Public methods
putNextEntry
void putNextEntry (ZipEntry ze)
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.
| Parameters |
|---|
ze |
ZipEntry:
the ZIP/JAR entry to be written |
