Class JarOutputStreamjava.lang.Object | +--java.io.OutputStream | +--java.io.FilterOutputStream | +--java.util.zip.DeflaterOutputStream | +--java.util.zip.ZipOutputStream | +--java.util.jar.JarOutputStream
- All Implemented Interfaces:
- java.util.zip.ZipConstants
- 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.

Constructor Detail
JarOutputStream
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
