[DESPERATE] UnsatisfiedLinkError: getBrowserType

[Michael Preston]

Hi

I am trying to get my applet, which is run using the Java 1.2
plug-in, to get hold of the Browser object so that I can manipulate the
vrml scene from my applet. Does anyone know why I am unable to do so?

I get the following error:

java.lang.UnsatisfiedLinkError: getBrowserType

at vrml.external.Browser.getBrowser(Compiled Code)

at VrmlSQLApplet.init(Compiled Code)

at sun.applet.AppletPanel.run(Compiled Code)

at java.lang.Thread.run(Thread.java:479)

Any help is _much_ appreciated

Cheers
