Introduction

Using the Java™ Pack API, you can create Java programs that interface with IBM® InfoSphere® DataStage® and QualityStage® Designer server and parallel jobs. Your Java program can:

• Produce (write) rows that are used within the job. In this scenario, the Java program is a source in the job.
• Consume (read) rows that are supplied on an input link. In this scenario, the Java program is a target in the job.
• Process rows from an input link and generate rows on the output link. In this scenario, the Java program acts as a transformer.
• Query column and stage metadata.
