This is my first weblog and wanted to present a simple one. I realized there are less topics about SAP GUI for JAVA and have come up with this blog which will be useful for new comers in SAP Enterprise Portal. This document provides quick info on installation & configuration.

SAP GUI for JAVA can be used as Stand alone and also be used as an applet in a web browser. The functionality is identical to the standalone solution.


    • Sun Java Runtime Environment 1.4.2 (including Sun Java Plugin). JREs are available on
    • Java Runtime Environment 1.4 (including a Java Plugin 1.4) must be installed on the frontend computer
    • Installation
      1. Download the most recent SAP GUI for JAVA from the following address:

  &nbsp Download   PlatinGUI-Win32-640r4.jar

  &nbsp Download Documentation – (for  Further Refrenece)

2. Copy the PlatinGUI-Win32-640r4.jar  to a folder.


3. Unpack the file using jar -xf  PlatinGUI-Win32-640r4.jar


4. Contents of Jar extracted to the folder.


5. Open demo.html in notepad, go to the line

var connectionData = ‘conn=/H/’;

Suppose if:
SAP Server  Name – sapprod
System Number – 00 (3200), if 01 (3201)
Domain &#`п  xyz @ „

    ace ü¦Ï line with
var connectionData = ‘conn=/H/’;

5. Execute demo.htm and you are all set to use SAP GUI for JAVA (Same as WinGui)


Making JAVA GUI accessible via Web.
a) Open IIS Manager
b) Under Default Website create a new virtual Directory
c) Default Website -> New -> Virtual Directory
d) Under Alias specify ‘javagui’.
e) Next under directory, specify ‘D:\javagui’
f) Under Access Permissions – Read, Write, Run,  Execute. Choose finish.


g) Right Click on Virtual-> Open Properties and under Documents add demo.htm.


h) Open a browser, type the url http://


    1. Specify the folder name



    1. After successful installation, click OK on message box.
    2. After installing as Stand alone application, you can access the SAP GUI by executing ‘SAPGUI for Java 6.40rev4’ Icon from desktop.



    1. Or create a file javagui_systems.txt with content
      R3 DEV : conn=/H/
      BW DEV : conn=/H/
    2. and refer it in configuration settings Options ->



Configuring JAVA GUI for SAP EP

Choose System Administration -> System Configuration -> Service Configuration.

Applications -> -> services -> Transaction_Configuration

Enter the values for the following properties:
SAP GUI for Java only: application/x-java-applet;version=1.4.1_02 (MIME Type of Java Plug-in)

SAP GUI for Java only: http://sapepdev/javagui (Enter a fully-qualified URL that refers to the Java installation directory on the Web Server) –


For restarting the application , Right click on the application and select administrate


On Application Details, Click on Restart under list of Services


Now SAP transactions / applications can be accessed using Java Gui as a stand alone application as well via web through browser. In EP Create a SAP Transaction IView and select JAVAGUI as SAP GUI type for presenting screen in JAVA GUI.

SAP note 454939 tells limitations of SAP GUI for JAVA.

    Hi Praveen,

    I tried out the Java GUI following your weblog. The Java GUI works fast & looks great (same like Win GUI), when compared with the Web GUI.

    Great Work! We look ahead for more EP weblogs from you.

      Hi Saad,

      No, not all. You have an option whether to install on client or not. If you dont want to  install then select ‘no’ on the popup (step h. Sun Java Runtime Environment 1.4.2 is the only requirement at the client desktop. The weblog describes both options (with/with outs standalone installation).

      Hope this helps.
