When you design your Business Process Server process with Progress Developer Studio for OpenEdge, the configuration parameters of the File Adapter are defined using the File Adapter Configurator. These parameters include:
File name and path.
Mode — read, write, or append.
File format — Text, Delimited-text, XML, Velocity template, or custom format.
After you specify the file format, the File Adapter configurator verifies if the given format requires any additional configuration. In case additional configuration is required, the configurator loads and displays the corresponding File Configuration Plug-in GUI.
Some file formats do not require any additional user-defined configuration.For example, plain text files can be read, written or appended to, without the need for File Adapter to know anything about the meaning of the data in the file. In such cases, the plug-in does not have its own format-specific GUI. On the other hand, extracting data from an XML file requires the XPath statement to the specific field to be configured, and the XML plug-in has a GUI configurator that allows browsing the XML template and entering XPath expressions.
File name and path.
