When I use Safari browser (4.0.4), the following error report is generated into the Java Console:

java.net.MalformedURLException: no protocol:
at java.net.URL.<init>(Unknown Source)
at java.net.URL.<init>(Unknown Source)

It's important to note that with other browsers (ie: Internet Explorer, Firefox, Chrome) no error is generated.

Can somebody help me? Please consider that I'm a very beginner.

Hi.

i think you need to dload this plug ins because safari is using another plugin or maybe u need to use another protocol.

try to read this: Java Embedding Plugin

Sure, no prob.

Cheers.

The applet tag is deprecated and you should instead use object.

See HTML object tag

        <object codetype="application/java" classid="ParametersApplet.class" width=500 height=200 name="PA1">
	    <param name="name" value="Tri Angle">
	    <param name="color" value="blue">
	    <param name="subject" value="math">
	    <param name="activity" value="reading">
	    <param name="food" value="bread">
        </object>

// Json

Thanks Json,

I've followed your suggestion and the folloeing code works with Firefox and IE, but doesn't work with Opera and Safari. Do you have any suggestion how to modify the code to properly work also with Opera and Safari? Please consider that I'm very begginer.
