This works fine in Win95 appletviewer, but gets java.lang.NoSuchMethodError when running in MS Internet Explorer. I've added update, init, and main methods, but still get the same error. What method am I missing and how do I see java error log in MSIE? Source code is below. I am using ObjectAda 7.1 on Win95. I have set PATH and CLASSPATH in AUTOEXEC.BAT: SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;C:\USR\BIN;C:\JDK1.1\BIN SET CLASSPATH=.;C:\WINDOWS\JAVA\CLASSES\CLASSES.ZIP;C:\PROGRA~1\AONIX\OBJECTADA\ JAVALIB\ADACLASS.ZIP -- Terry J.
