Constructor Detail

JarOutputStream

public JarOutputStream(OutputStream os,
                       Manifest manifest)
                throws IOException

Constructs a new JarOutputStream using an output stream. The content of the Manifest must match the JAR entry information written subsequently to the stream.

Parameters:

os - the OutputStream to write to

manifest - the Manifest to output for this JAR file.

Throws:

IOException - if an error occurs creating the JarOutputStream.

JarOutputStream

public JarOutputStream(OutputStream os)
                throws IOException

Constructs a new JarOutputStream using an arbitrary output stream.

Parameters:

os - the OutputStream to write to.

Throws:

IOException - if an error occurs creating the JarOutputStream.

Method Detail

putNextEntry

public void putNextEntry(ZipEntry ze)
                  throws IOException

Writes the specified ZIP entry to the underlying stream. The previous entry is closed if it is still open.

Overrides:

putNextEntry in class ZipOutputStream

Parameters:

ze - the ZipEntry to write to.

Throws:

IOException - if an error occurs writing to the entry.
