Exception: java.lang.ClassNotFoundException: DisiConnectionApplet.class

I have checked and found the class is on proper place… I googled the issue and found that there might be any issue in IE settings… but didn’t get any proper solution…

I am using IE 6.0 with below Java plug-in :::::::::::::

Java Plug-in 1.6.0_11

Java™ Plug-in 2 SSV Helper

Java™ Plug-in SSV Helper

Web Browser Applet Control

Please let me know what should be done on this case…???

Hello Soumya,

Here are following things might cause that problem.

  1. check the expiry date of applet certificates.

  2. the version differences between applet, browser or domino server.

    For ex: the compiled version of applet is 1.3 and your browser or domino server might be more than or less than that one.

  3. see the required jars for the applet is in proper place.

Regards,

Sreedhar

This is an customised applet, so here is no expiry date.

The version in Notes is JDK1.2 where the applet is compiled and in IE it is using Java Plug-in 1.6.0_11 is installed.

The new version of jave should support older verions of compiled java files.

The design has not been changed. So I think the Jar files are in proper place…

So what you suggest??? Should I complile the whole applet code and create the jar file again???

yes, if you can do that you might get clear idea where the applet is failing.
