There are three ways to develop work item viewers. The easiest way is to use the Work Item Viewer dialog, accessed from the Viewers tab in the Process Flow editor. This dialog allows you to build a viewer based on an existing viewer template by dynamically adding form elements. You can use one of the templates included with EPX, or you can create your own custom template by coding one with HTML. You can also use HTML to create a standalone viewer that will not be dynamically editable. If you want to include Java code in a viewer, you can develop a viewer or viewer template as a Java Server Page (JSP), using JSP code instead of HTML.
Each of the three methods of creating work item viewers — using the Work Item Viewer dialog, coding with HTML, and coding with JSP — are discussed in turn in the following sections.
