      - Testing Java™ applications
        You can use HCL OneTest™ API to test Java™ applications.
      - Testing Java™ Message Service (JMS) systems
        Use the generic JMS plug-in to connect HCL OneTest™ API to a wide range of EAI platforms, which includes any vendor that provides an implementation of this Java™ standard. JMS provides a way of separating the application from the transport layer of providing data. The same Java classes can be used to communicate with different JMS providers by using the JNDI information for a specific provider. The classes first use a connection factory to connect to the queue or topic, and then use populate and send or publish the messages. On the receiving side, the clients then receive or subscribe to the messages
      - Testing Java™ objects
        You can import Plain Old Java™ Objects (POJOs) from JAR files into HCL OneTest™ API in order to parse and construct messages containing the serialized forms of those objects. You can construct and parse the Java objects and perform validation, but you cannot test the objects directly.
      - Testing with Apache Camel components
        You can use HCL OneTest™ API to create tests and stubs by setting up an Apache Camel component in a Rational® Integration Tester project. You can configure the technology endpoints supported by the Camel component as the physical resources in the HCL OneTest API project and test for the services provided by the technology.

      - Testing with the email transport
        When you use applications in your test environment that use email services, you can use HCL OneTest™ API to create tests and stubs for testing the email services. You can set up an email transport in a HCL OneTest API project and configure the email servers as the physical resources in the HCL OneTest API project, and then test the email services.
      - Testing with Envoy Proxy (Experimental)
        You can use HCL OneTest™ API to record the HTTP traffic on the Envoy Proxy by using the Experimental HTTP Tap Filter feature of the Envoy Proxy.
      - Testing with the File transport
        As with any other transport, the File transport includes both logical and physical configurations. Tests and stubs are associated with the logical file, which represents an abstraction of the file and is the same for all environments. The physical File Access configuration includes connection details, and you can configure a different physical File Access for each environment.
      - Testing with the FIX transport
        You can use the Financial Information eXchange (FIX) transport and FIX dictionaries in HCL OneTest™ API to help you test trade-related messages and the systems that use them.
      - Testing with the HTTP transport
        To provide support for HTTP-based communications, you must configure and run HCL OneTest™ API by using the HTTP transport and SOAP message formatters.
