itextdotnet question

[Guest]

hi,
i'm trying to use iTextDotNet library to generate files .pdf on the fly from
my webform;
for example i got the following code in my page_load :

Dim ms As New MemoryStream
Dim document As New document
Dim writer As PdfWriter = PdfWriter.getInstance(document, ms)
document.open()
document.add(New Paragraph("Hello World"))
document.close()
Response.ClearContent()
Response.ContentType = "application/pdf" Response.BinaryWrite(ms.GetBuffer)
Response.End()

that code work fine on localhost and on the hostbasket server, but don't
work at all on another hosting server;
the code require references at
itextdotnet.dll
Gnu.Classpath.Core.dll
Gnu.Classpath.JAXP.dll
vjslib.dll
vjscor.dll
vjsnativ.dll
(because itextdotnet is made in j#);
i xcopy these dlls in the bin folder of my webapp.

but i got a java.lang.UnsatisfiedLinkError in the PdfWriter GetInstance

is there someone who want give me an hint?
thanks in advance
