URLFileItem (webMethods CAF

java.lang.Object
- com.webmethods.caf.faces.data.attachments.URLFileItem

public class URLFileItem
extends Object

Simple implementation of the FileItem interface that can be used for adding/updating attachments programmatically from a URL, local file or web application resource. For loading web application resources this class must be used during JSF life cycle.
NOTE: only the methods needed for attachments are implemented, so this should not be used as a generic FileItem in other contexts.
Usage Example:

                IAttachmentsProvider provider; //get or create attachment provider here

                //add a local text file
                FileItem item = new URLFileItem(new File("c:\\file.txt"));
                provider.addAttachment(item, "UTF-8");

                //add a local binary file
                FileItem item2 = new URLFileItem(new File("c:\\file.gif"));
                provider.addAttachment(item, null);

                //add a remote binary file
                FileItem item2 = new URLFileItem(new URL("http://localhost/file.gif"));
                provider.addAttachment(item, null);

                //add a web application resource file
                FileItem item2 = new URLFileItem("/MyPortlet/myfile.gif");
                provider.addAttachment(item, null);

When used in a java bean context location property should be set with a URL, local file path or a web resource path.
