Did you mean a NullPointerException? If so, a) Please don't SHOUT at us. and b) Please be specific. Programming is hard. Debugging is harder. Debugging an application remotely, where the exceptions and errors are being 'paraphrased' is even harder again. Don't make it hard on us (please). >...The exception occured at this line System.out. >println(view.getProperty("Default_Zoom_Type")); I would have guessed that if any property either does not exist, or is not defined for that PDF file, it returns null. OTOH, that does not explain the exception, since the output should simply have been null like this line would print.. System.out.println((String)null); Indeed, the NPE suggests the viewer itself is null, but if so, the page count could not have been referenced on the previous line*. * > System.out.println(view.getPageCount()); Which leads me to.. Please copy/paste the stacktrace. As well as the output you are seeing. -- Andrew Thompson http://www.athompson.info/andrew/ Message posted via JavaKB.com http://www.javakb.com/Uwe/Forums.aspx/java-gui/200711/1 --- * Synchronet * The Whitehouse BBS --- whitehouse.hulds.com --- check it out free usenet! --- Synchronet 3.15a-Win32 NewsLink 1.92 Time Warp of the Future BBS - telnet://time.synchro.net:24
