Following are a number of Java samples that use jPDFNotes:

jPDFNotes in a standalone frame

SimpleFrame.java - A simple program that embeds jPDFNotes into a JFrame.

---

jPDFNotes in an Applet - jPDFNotes can be run inside a browser as an applet. The following sample code provides a simple HTML page that contains an applet that in turn contains jPDFNotes.

PDFNotesAppletJava - A Java applet that incorporates jPDFNotes. The applet takes a number of parameters from the HTML to load a document on initialization and to turn toolbar buttons on or off.

To run the applet on your server, you will need the following files:

pdfnotes.html - A simple HTML page that launches the applet.
jPDFNotesS.jar - The jar file containing the jPDFNotes classes.
notessamples.jar - The jar file containing the jPDFNotes samples.

jPDFNotes with custom annotation tools - jPDFNotes provides the API to let the host application create custom annotations and add them as tools in the toolbar or drop down menus. This sample does a number of customizations: It adds three buttons to the toolbars that create custom annotations, it adds a custom rubber stamp to the stamp drop down menu, and it sets the color of free text annotations to be always red.

SimpleFrame.java - A simple program that shows a Window with the jPDFNotes componennt inside. The program adds the custom buttons to the toolbar as well as the menu entry to the rubber stamp drop down menu.

MyNotesBean.java - A class that extends PDFNotesBean to override the startEdit() method. In the implementation of the method, if the annotation is a free text annotation, the color is set to red.

jPDFNotes with a custom saver - jPDFNotes allows the host application or applet to define a custom "saver". This is useful when the PDF files should be saved back to a server instead of the local file system.

The following sample illustrates how to register a custom saver with jPDFNotes and implements saving back to a web server, using a multipart file upload POST message.

AppletWithUpload.java - A Java applet that incorporates jPDFNotes and also implements IPDFSaver, the interface necessary to register a custom saver. The IPDFSaver interface requires a save method that will be called when the user presses the saver button. The implementation of this method sends the PDF content to a web server using a multipart form POST with a file upload entry.

FileUploadPOST.java - This class implements the POST message to send the file contents back to the server.

CookieJar.java - Implements a cookie container to interact with the web server.

UploadStream.java- This stream passes the data through to the HTTP connection and calculates an MD5 digest for the content, to be appended to the multipart message.

ByteCounterSream.java - This stream is used to determine the length of the PDF content when creating the POST message.

On the server, we provide sample pages to receive the PDF content in a few technologies:

upload.php - A PHP script to receive the PDF file.

UploadServlet.java - A Java servlet to receive the file. This servlet uses the Apache Commons I/O and FileUpoad packages to parse the multipart message. These jar files can be downloaded free of charge from the Apache website.

upload.asp and uploadlib.asp - Classic ASP script that can receive the PDF content.

upload.aspx - ASP.NET script to receive the PDF content.

The HTML file to launch the applet and the JAR files that are referenced by the applet are:

pdfnotesupl.html - A simple HTML page that launches the applet.
jPDFNotesS.jar - The jar file containing the jPDFNotes classes.
notessamples.jar - The jar filie containing the jPDFNotes samples
