Applets<br />
Anyone have any ideas what is going wrong?<br />
Answer: The parseDouble method was only added to <strong>Java</strong> in JDK 1.2<br />
Browsers typically only support <strong>Java</strong> 1.1<br />
If you have the JRE installed, you can run <strong>Java</strong> 1.2 applets. But you must also change the HTML<br />
code that embeds the applet. Check javasoft.com. I believe they have a program which will<br />
automatically change the tag to and add whatever else is needed. It's been a<br />
while since I've done applets but I do remember running across a similar problem.<br />
Q: In my applet I have a bunch of gif's in my JAR file. When I try to access a gif using:<br />
Image img = getImage(getCodeBase(), "image.gif");<br />
everything works fine under Microsoft Internet Explorer but it does not under Netscape and<br />
appletviewer. Of course I do not have any gifs in my CodeBase directory on server.<br />
Any idea why?????<br />
Answer: Because this is not how you access resources in a Jar file. You need to use<br />
getResourceAsStream if you want to access GIFs from Netscape. Look at:<br />
http://developer.iplanet.com/docs/technote/java/getresource/getresource.html<br />
for example code. This same code will work in Sun's Appletviewer.<br />

Q: How do I get JVM version in Internet Explorer?<br />
Q: When you open the <strong>Java</strong> Console through internet explorer, it prints the following useful line at the<br />
top:<br />
Microsoft (R) VM for <strong>Java</strong>, 5.0 Release 5.0.0.3318<br />
We would like to be able to obtain the above String (or atleast the 5.0.0.3318 part of it) through a <strong>Java</strong><br />
Applet / <strong>Java</strong>script at runtime.<br />
Does anyone know of any handy methods that allow access to this String ? I've looked in all the<br />
System.properties, but it wasn't there. Is it stored in the user's registry anywhere ?<br />
Answer: just for Microsoft't VM!<br />
try :<br />
class test{<br />
public static void main(String[] args){<br />
String build;<br />
build=com.ms.util.SystemVersionManager.getVMVersion().getProperty ("BuildIncrement");<br />
System.out.println("Using build "+build);<br />
}<br />
}<br />

Q: I wonder if there is a way to find out if a button in an applet has been clicked, no matter which<br />
of the buttons in an applet it might be.<br />
Of course I can write, with a particular button (if event.target==button1) but maybe there is a syntax<br />
