I have the following requisite three files in a local directory "C:\Users\thomas\Documents\vinu\hyperdyn\src\":
*.html
*.jar
*.jnlp
When I double click the html file to launch it, the applet fails to load and the Java console prints the following error message:
Java Plug-in 1.6.0_26
Using JRE version 1.6.0_26-b03 Java HotSpot(TM) Client VM

Error while initializing manager: MissingFieldException[ The following required field is missing from the launch file: <jnlp><applet-desc>width], bail out
The strange thing is that I do have the height and width parameters specified in the jnlp file:
<applet-desc
name="..."
main-class="..."
width="640"
height="355">
</applet-desc>
The stranger thing is that if I modify the path to the local directory, for example, add a dash to make it "C:\Users\thomas\Documents\vinu\hyperdyn\src-\", then the applet launches without any error! I am working on Windows 7 Home Premium, Service Pack 1. Any insights anyone may have will be greatly appreciated.
