Not only possible, but already available! See the sample program "com.ibm.jzos.sample.ZipDatasets" in the JZOS Sample programs download, which is available here: http://www-03.ibm.com/servers/eserver/zseries/software/java/products/jzos/jzossamp.html
Like most Java programs, you can run this from a shell or using the JZOS Batch launcher. You can also run java under TSO, using REXX/bpxwunix or BPXBATCH. I've clipped the comment header from the sample class below. Kirk Wolf Dovetailed Technologies http://dovetail.com /** * A sample Java main class that can be invoked to create a Zip archive from one * or more datasets or PDS members. Datasets are treated as text and converted * from EBCDIC to ASCII (ISO8859-1) or to the specified target codepage. * <p/> * Details on the input arguments to this class are available by executing * the main method with no arguments. (see {...@link #usage()) * <p/> * Example: Zip several partitioned datasets to a Unix zip file: <pre> com.ibm.jzos.sample.ZipDatasets test.zip sys1.proclib(asm*) hlq.**.jcl </pre> * <p/> * Example: Zip all datasets matching two patterns to a dataset: <pre> com.ibm.jzos.sample.ZipDatasets //hlq.backup.zip payroll.*.data gl.**.dat* </pre> * <p/> * Example: Zip data using DDs and input and output: <pre> com.ibm.jzos.sample.ZipDatasets //DD:ZIPOUT //DD:INSEQ1 //DD:INPDS1 //DD:INPDS2(FOO*) </pre> * <p/> * The following classes and APIs are demonstrated: * @see com.ibm.jzos.ZFile * @see com.ibm.jzos.ZUtil * @see com.ibm.jzos.CatalogSearch * @see java.util.zip.ZipOutputStream * @see java.util.regex.Pattern * @see java.util.regex.Matcher * @see ZipDatasetSource the class which creates Zip archive entries for each input dataset/pattern * @since 2.3.0 */ On Fri, Jun 26, 2009 at 3:21 PM, McKown, John <[email protected]> wrote: > > I've seen a lot of messages about InfoZIP and other z/OS compatible zip > creation software.
