Hi,
I think at least the last one has been mentioned on the mailing list:
http://today.java.net/pub/a/today/2005/10/20/accessing-pdf-with-acrobat-viewer-javabean.html?page=1
http://www-128.ibm.com/developerworks/opensource/library/os-javapdf/
http://www.adobepress.com/articles/article.asp?p=420
I think the first one has been omitted intentionally.The Acrobar Viewer Javabean is something that Adobe doesnt support anymore.And in a response received from Richard Bair, a pdf viewer created by him happens to be lying in one of the code attics of the JDIC project.
Thanks for sending the other t
