Class SimpleFileExportBean

java.lang.Object

com.webmethods.caf.faces.bean.SimpleFileExportBean

All Implemented Interfaces:

IFileExportBean, IFileExportBeanEx

public class SimpleFileExportBean
extends Object
implements IFileExportBeanEx

This is a simple implementation of IFileExportBeanEx that is java bean compatible. If created as a bean then exportFileName, exportContentType and either binaryData or textData properties must be set. For textData, exportCharactersEncoding should be set as well.
