FWIW, the "jar" command is just a special launcher for the Java class
"sun.tools.jar.Main". The heavy lifting is done by the "java.util.zip"
package, which provides a public API.
The "jar" command is written only to support z/OS Unix files, but the
ZipDatasets sample class (source provided) supports z/OS datasets.
The ZipDatasets sample is written so as to read the datasets as a text
stream (newlines added) and write the output to Zip entries that are
converted to ISO8859-1. The "-t" option can be used to specify a
different target encoding.
Usage: com.ibm.jzos.sample.ZipDatasets [-t targetEncoding] outfile
indsname...
where:
-t targetEncoding can optionally specify the codepage name to encode the
text data as it is written to the Zip file. If not specified,
this defaults to ISO8859-1 (Latin/ASCII)
and outfile is either:
- a Unix file path name: /path/to/some/file.zip
- a dataset name: //A.B.C
- a PDS member name: //A.B.C(MEM)
- a DD name: //DD:XYZ
- a DD name and member: //DD:XYZ(MEM)
and each (at least one) indsname is either:
- a dataset name: //A.B.C
- a dataset pattern: //A.*.D
- a PDS member name: //A.B.C(MEM)
- a PDS member pattern: //A.B.C(D*X)
- a DD name: //DD:XYZ
- a DD name and member: //DD:XYZ(MEM)
- a DD name and member pattern: //DD:XYZ(D*X)
\"//\" prefixes may be omitted from indsnames
All dataset names are assumed to be fully qualified.
