Tools and samples to help use Java on z/OS.

Sample z/OS Java programs.

• compress Compress and decompress z/OS sequential datasets using gzip compatible compression. Data can be decompressed on other systems using gzip and processed by programs that understand the z/OS record formats. Likewise, programs on other systems can write z/OS compatible records, compress the data using gzip and it can be uncompressed to a z/OS dataset.
• catalog Samples demonstrating use of the com.ibm.jzos.CatalogSearch class to use the z/OS Catalog Search Interface from Java.
• show-classpath A simple program to help diagnose classpath programs. It displays the CLASSPATH environment variable, and the resolved CLASSPATH entries from the class loader.
• z-mail A program to send email from a z/OS batch job. The sample demonstrates using Gmail, using a TLS connection and a userid and password for authentication.

JCL Procedures and jobs to compile and run Java on z/OS.

3 PROCs are provided:

• JAVAC - Compile a Java program using BPXBATCH
• JAVAG - Run a Java program as a z/OS batch job using the JZOS Batch Launcher
• JAVACG - Combine the JAVAC and JAVAG procs to compile and run a Java program in one job.

Sample jobs are provided to demonstrate use of the PROCs.
