SAP GUI for Java - com.sap.platin.GuiApplet2 ClassNotFoundException

Former Member — Tue, 29 Aug 2006 15:03:44 GMT

Hi,

installed components on my system:

- SAP GUI for Java 7.00 and Java

- j2sdk1.4.2_09

I got the following error msg if I try

to start the applet from the installation manual:

"java.lang.ClassNotFoundException: com.sap.platin.GuiApplet2"

Do I have to add an special *.jar file to the environment variables?

thx 4 answer,

Rene.

my html code:

<BODY>

<APPLET CODEBASE = "." ARCHIVE = "GuiStartS.jar"

CODE = "com.sap.platin.GuiApplet2"

WIDTH = "100%"

HEIGHT = "100%">

This page requires a Java Runtime 1.4 and a SAPGUI for Java to view.

</APPLET>

</BODY>

Hello Rene,

not knowing the details (platform, browser, what's on the web server where the html page is) I can not point you directly to what's wrong.

One potential reason for your particular problem could be that the jars are not located in the same folder than your html file you are using. (The codebase in your case is ".", so there has to be at least a GuiStartS.jar there for launching the applet, even in case your SAP GUI for Java is already installed locally on your client.

What you should do is:

- make sure to use the JRE, not JDK

- read how to setup the web server in "8.2. Web Server Installation" in the manual which comes with SAP GUI for Java. Basically create an empty folder on your web server and unpack the content of the Java archive 'Platin-<platform>-<version>.jar' into the empty folder using some archive program.

- use the "demo.htm" sample file, which you then will find in the folder where you unpacked the 'Platin-<platform>-<version>.jar'. It takes care of the different cases of using the object, embed or applet tag depending on the browser and platform you use.

Best regards

Hi Rolf-Martin,

thx 4 ur help!

The problem was that the jars were not located in the same folder than my html file,

but is this the best solution for the problem?

Is it possible that I set a special environment variable or something else?

Ciao,

Rene.

Hello Rene,

if your own html pages referencing SAP GUI for Java are not located in the web server installation directory, you will have to adapt the CODEBASE paramter accordingly.

See also 8.3. Applet HTML Reference, section "Demo page".
