Constructor Detail

JarOutputStream

public JarOutputStream(OutputStream os,
                       Manifest mf)
                throws IOException

Constructs a new JarOutputStream using os as the underlying stream. Manifest information for the JarFile to be written is obtained from the parameter Manifest, mf.

Parameters:

os - The OutputStream to write to

mf - The Manifest to output for this Jar.

Throws:

IOException - If an error occurs creating the JarOutputStream

JarOutputStream

public JarOutputStream(OutputStream os)
                throws IOException

Constructs a new JarOutputStream using os as the underlying 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 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

Throws:

IOException - If an error occurs writing the entry
