Connection properties specified on a server or at design time

When you use a stand-alone adapter, you specify that the import or export configuration settings come from a Java™ Naming and Directory Interface (JNDI) resource instead. You can also specify that user and password settings come from a Java Authentication and Authorization Service (JAAS) alias. The benefit of using JNDI and JAAS resources is that an environment-specific resource that a system administrator sets up controls the configuration settings and, therefore, you do not need to be aware of all the environment details. The drawback is that the resources need to be configured before deployment with the proper names to tie those resources to the application; otherwise, the adapter might not function properly.

When you use the external service wizard with adapters that access enterprise information system (EIS) systems, the wizard detects the connection properties. When you build your import or export component, you can use these properties and modify the settings as needed. Because you are not using a stand-alone adapter and a JNDI resource, the settings are related to the settings defined in the application EAR. Whoever develops the application must set the values at design time. Because some environments might require different settings, the developer might have to modify the adapter configuration after each deployment.
