Hi, After trying to find any errors with my xml files that have been giving me validation problems, I have now discovered that oXygen is refusing to transform any of my documents to PDF - even when the documents are valid. The error message is: E|The process ended wide code : 1 The error was : Exception in thread "main" Transformation to html is successful. I have JAI installed for FOP recognition of .PNG files (installed several weeks ago). oXygen 5.1 Apache Xerces-J 2.6.2 Apache Xalan Java 2.5.1 SAXON_6 6.5.3 SAXON_8B 8.1.1 Apache FOP 0.20.5 Jing 20030619 Trang 20030619 Apache NekoHTML 0.9.4 OASIS DocBook XML DTD 4.3 DocBook XSL 1.67.2 TEI DTD P4 TEI XSL 2.1 Any clues on what I can do here?
