When you use IBM® InfoSphere® DataStage® to
invoke Java code, you can choose from a collection of connectivity
options. For most new jobs, use the Java Integration stage, which
offers better functionality and performance.
The Java Integration stage can be used in the following topologies:
- As a source with one or more output links
- As a target with one or more input links and zero or more reject
links
- As a transformer with one or more input links and one or more
output or reject links
- As a lookup stage with one reference output link
The Java Integration stage is one of several different stages that
invokes Java code. In addition to the Java Integration stage, the
following stages are available:
- Java Client stage
- Java Transformer stage
If you want to integrate Java code into a server job, you must
use one of the older stages instead of the Java Integration stage.
If you have jobs that use the older stages and want to use the
Java Integration stage, use the Connector Migration Tool to migrate
jobs to use connectors.
