Java Development Environments

Generated Java beans can be used to add host access tasks to applications created in any Java application development environment. Each bean includes additional read-write and read-only methods representing the inputs and outputs built into the task. Using Web Builder, for a Java environment, you can build ICA Task Files or ITask beans.

Java Interfaces Description
IConnectorAccess (ICA) An XML-based API that is typically a bit more flexible than the other APIs.
ITask A Java bean-based API that has a smaller footprint than ICA, and is typically slightly faster because no XML parsing is needed. Java beans contain a single client operation for each bean and implement the ITask interface. Each bean includes set and get methods as well as set methods representing the inputs and outputs built into the client operation. Beans provide a listener interface for monitoring client operation execution.

Developing for Java Environments

When writing code to access your client operations through Java beans, you should typically follow this workflow:

  1. Instantiate the bean.
  2. Set the bean's input properties.
  3. Execute the task.
  4. Get the bean's output properties.
  5. Terminate the bean.

When writing code to access your client operations through ICA you create a Java application that sends input to and receives output from your Transaction Designer client operation, using XML described by the metadata in your Web Builder-generated task file
