Re: ChromeJarResourceLoader and winXP jdk142 and webstart

Hi Ross,

thanks a lot for the hint. Fortunatly I have not yet
come across all the problems you are mentioning below
:-) I have been able to cope with my problem by adding
the following line (with the %20): 

  String jarFileName =ClassUtils.getJarFileName(
anchor );
+ jarFileName = jarFileName.replaceAll("%20"," ");  
  File file = new File( jarFileName );
  JarFile jarFile = new JarFile( file, false ); 

It looks like the problem arise from the spaces in the
"c:\program files" directory... Looks like a M$
conspiracy... In fact it looks like there is no good
URL-->File conversion method in java. The space
character has been escaped to %20 when calling the
URL.getExternalForm(), but there could be many more
characters that could undergo that transformation...
Seems scary! Perhaps it could be better to go directly
from URL --> JarEntry without going through the
java.io.File concept. What do you think about it?

Cheers,

Denis
