1 Using JavX Running Applications in a Web Browser or WinCE Device Presented by: Jarett Smith Eric Vanpaeschen

2 Presentation Outline Rich Internet Applications (RIA) Examples of Java Applets ProvideX JavX Clients JavX SE Overview Examples WindX vs. JavX SE Installation and Set Up Security Considerations Accessing local Printers JavX AE Overview J2ME Runtime Environments

3 Rich Internet Applications (RIA) Web and business applications are converging In 2005, Gartner Research predicted: "By 2010, at least 60 percent of new application development projects will include RIA technology, and at least 25 percent of those will rely primarily on RIA."

4 Rich Internet Applications (RIA) Some companies will choose to migrate from client applications (i.e., WindX) to RIA alternatives that can deliver the same rich UI and performance RIA market will be dominated by four technologies: AJAX Java Flash Microsoft s recently announced Silverlight (.NET)

5 RIA with Java 91% of all PCs run Java platform 77% of all Java technology-enabled PCs run Sun s Java Platform, Standard Edition (Java SE platform)

6 RIA with Java Distribution through PC OEMs Nine of the top ten PC OEMs ship the Java SE Runtime (JRE) software Representing > 60% of all shipped PCs 58 white box vendors have signed JRE software redistribution Download/Installs > 44 million installations/month for the last six months on Windows > 50 million in January, February, and April 2007

7 Examples of Java Applets Map24.com Maps, directions, local search in an applet Used on Yahoo s European sites One Million Applet Downloads a Day

8 Examples of Java Applets Google PowerPoint Viewer

9 Examples of Java Applets MySpace Project Inglewood Media file upload applet

10 ProvideX JavX Clients JavX SE (Swing Edition) Java-based thin client with similar functionality to WindX Enables ProvideX applications to run on any number of client platforms (Windows, Linux, Apple) that support the Java Standard Edition JavX AE (AWT Edition) Provides a simpler GUI designed specifically for handheld devices that support the Java Micro Edition

11 JavX SE Overview Emulates WindX in Java Runs on a wide range of operating systems and platforms: Windows, Linux, Apple, etc Runs as a Rich Internet Application (RIA) in a web browser Delivers user interface (UI) and performance of WindX, but without the installation and maintenance requirements

12 JavX SE Examples Running MAS 90 Invoice History in a web browser

13 JavX SE Examples Running MAS 90 Customer Maintenance in a web browser

14 WindX vs. JavX SE WindX Requires a Microsoft Windows OS ProvideX program Runs in a ProvideX executable Has access to all ProvideX commands JavX SE Emulates WindX in Java Runs on a much wider range of Operating Systems and platforms

15 WindX vs. JavX SE WindX = ProvideX No graphical surprises JavX SE Relies on Java Look & Feel GUI controls will differ from Microsoft controls As the following screen shots show, object sizes and locations will differ between WindX and JavX SE

16 WindX on Windows XP

17 JavX SE Windows Look & Feel

18 JavX SE Metal Look & Feel

19 JavX SE Mac Look & Feel

20 What JavX SE Cannot Do RS-232 and Telnet connections Access to Local ProvideX programs Local KEYED/INDEXED files Local printers Local ports (serial/parallel) Microsoft ActiveX and COM objects BMP pictures 'FILL' crossline/crosshatch patterns Some GUI objects have limited properties

21 What JavX SE Does Better FIN( ) function / OPTION mnemonic have JavX SE specific extensions Access to resources through the hypertext protocol (http/https and ftp) Access to local Java classes and applications Allows JavX SE to be used as a gateway between ProvideX and Java See also the Client-Server Reference PDF

22 What JavX SE Does Better Examples: 0010 DEF OBJECT 0020 EXECUTE "[wdx]on EVENT java.awt.event.mouselistener;mousepressed FROM " +STR(JBUTTON)+" PREINPUT 10" 0030 JBUTTON'SETLABEL("Click Me") 0040 OBTAIN A$; IF CTL<>4 THEN PRINT CTL,A$; GOTO *SAME 0050 DELETE OBJECT JBUTTON 0010 PRINT 'CS', 0020 PRINT 'PICTURE "

23 *windx.utl Support The following entry points are available get_addr get_val/get_num get_tcb get_file_box/read/write spawn/spawn_nohup

24 Image Support JavX SE application is able to access local resources JavX SE applet cannot access local resources Add pictures to the archive General note about JAR files: JAR means Java ARchive and, as the name indicates, it is an archive. By using a ZIP tool, you can extract/replace/add components from/to the archive

25 Image Support Install pictures on the local disk (application) Install pictures on the server disk (applet)

26 Managing Limitations Do not report missing GRID properties: PRINT 'OPTION'("REPORTGRIDERRORS","FALSE"), No INI file, so set graphic font / size: PRINT 'OPTION'("graphicfontname",Name$), PRINT 'OPTION'("graphicfontsize",Size$), Suppress Error 12 when calling local programs: Add LocalProgramName,Label= to arguments

27 Installation and Set Up On a desktop computer, Java Runtime Version 2 or later is required JavX SE application will try to connect to local NtHost server on socket Override these settings by Passing arguments in the launch command Changing the JavX.Properties (text) file that is contained within the JavX JAR file

28 Installation and Set Up JavX SE can run as an application or as an applet. When used as an applet, you will want to install the JavX Developer Kit. This contains: Current JavX version Documentation Some shortcuts Java runtime {optional} Page Generator Utility Page Generator Utility will allow you to generate an HTML page that is dependant upon the browser, the operating system, and the Java Runtime Environment (JRE) present on the client machine

29 Installation and Set Up

30 Installation and Set Up

31 Security Considerations JavX SE as an applet Browser will impose security restrictions Applet is either signed or unsigned Signed applet has the same rights and permissions as a Java application This means unrestricted access to the user's workstation and file system When unsigned, local access is denied

32 Accessing Local Printers Applet cannot access local printers Create a link file on a server that: Opens a *PDF* Prints to a file that is accessible through the internet Starts a SYSTEM_HELP command on that file when the channel is closed

33 Accessing Local Printers Driver Example:! javxpdf - JavXPDF driver CHAN=LFO,FID$=FID(CHAN); CLOSE (CHAN) PATH$="/home/domains/edias.com/public_html/" NAME$="reports/javxpdf.pdf"; ERASE PATH$+NAME$,ERR=*NEXT SERIAL PATH$+NAME$ OPEN (CHAN)"*PDF*;FILE="+PATH$+NAME$; SETFID FID$,ERR=*NEXT MNEMONIC (CHAN) '*X'=PGN+";OnClose;URL= EXIT OnClose: \ M$=MNM('*X',LFA),P=POS(" IF P \ THEN SYSTEM_HELP M$(TMP) EXIT

34 Things to Consider When using JavX SE Do you need access to local resources? Make sure images can be found Use fonts available to Java When using JavX SE applet Be aware of printer issues Keep security issues in mind

35 JavX AE Overview Standard Pocket PC (PDA) version of JavX Requires a Java 2 Micro Edition (J2ME), Connected Device Configuration (CDC) Personal Profile JRE Complete character UI support (fonts, lines and shapes, colors, pictures, etc.)

36 JavX AE Overview Mnemonics, system functions and variables (e.g., MSE, OBJ, FIN) are supported Supports the following GUI components Buttons: BUTTON, RADIO, CHECK_BOX Text Components: LIST_BOX, MULTI_LINES, DROP_BOX Vertical and Horizontal Scroll Bars Message Box Tool bar ProvideX Menu bar menus (not popup menus)

37 J2ME Runtime Environments We recommend IBM s WebSphere Everyplace Micro Environment (aka J9) CDC Personal Profile CDC Foundation Profile CLDC MIDP Many devices are shipped with a J2ME runtime environment installed or as a companion CD Search for J2ME Java Virtual Machines on the internet and you ll find dozens of vendors
