Java Transformation Overview

Java Transformation Overview

Extend PowerCenter functionality with the Java transformation. The Java transformation provides a simple native programming interface to define transformation functionality with the Java programming language. You can use the Java transformation to quickly define simple or moderately complex transformation functionality without advanced knowledge of the Java programming language or an external Java development environment. The Java transformation can be a passive or active transformation.
The PowerCenter Client uses the Java Development Kit (JDK) to compile the Java code and generate byte code for the transformation. The PowerCenter Client stores the byte code in the PowerCenter repository.
The Integration Service uses the Java Runtime Environment (JRE) to execute generated byte code at run time. When the Integration Service runs a session with a Java transformation, the Integration Service uses the JRE to execute the byte code and process input rows and generate output rows.
Create Java transformations by writing Java code snippets that define transformation logic. Define transformation behavior for a Java transformation based on the following events:
  • The transformation receives an input row.
  • The transformation has processed all input rows.
  • The transformation receives a transaction notification such as commit or rollback.
