Hi Luis,
Perhaps the 'codebase' is being confused by the php, so what if you remove it and specify the full path with pluginfile.php in the 'archive' attribute?
This is because I'm sure you are not using the 'pluginfile.php' as a URL within the jar file... http://stackoverflow.com/questions/5947063/how-to-specify-correctly-codebase-and-archive-in-java-applet
So it all depends on the folder stucture within the Jar file for the codebase attribute. Given the value of the 'code' attribute, I'd leave codebase out.
Cheers,
Gareth
