RE: [xsl] Accessing External Java Library

Hi Michael,

I think I'm now creating an instance of the class correctly but I'm
still getting some errors relating to a missing function when using non
static methods.

Once again, the messages give you the information, and once again, it's
in
the checklist that I gave you earlier:

> C:\Documents and Settings\cbourne\My Documents\PGPJava>java
> -cp .;C:\javapgp\iPG P.jar net.sf.saxon.Transform -TJ pgp.xml
> pgp.xslt Loading iPGP.iPGP Looking for method setArmor in
> Java class class iPGP.iPGP Number of actual arguments = 1
> Trying method getArmor: name does not match Trying method
> setArmor: name matches Method is not static

If you're calling a non-static method then you need to supply an object
instance as the first argument. The documentation tells you how.
