--- Comment #3 from Rafael Lopez <[email protected]> --- Hi there, I am having the same problem under Ubuntu 11.10, java-6-openjdk and Apache POI 3.9 (downloaded from Maven Repository). My exception trace is: java.lang.NullPointerException at org.apache.poi.hslf.usermodel.SlideShow.buildSlidesAndNotes(SlideShow.java:401) at org.apache.poi.hslf.usermodel.SlideShow.<init>(SlideShow.java:109) at Main.getPresentation(Main.java:56) at Main.method2(Main.java:48) at Main.main(Main.java:14) I am attaching my source code too. Note that method1() works while method2() is the one that throws the exception. Maybe this additional information gives you some guidance: The truth is that once I had the same experience just with Sun JDK, but without using Apache POI at all. I just serialized some objects creating a new ObjectOutputStream each time and after overwriting the same file several times I got an StreamCorruptedException. There was a bug in the forums of Sun JDK at that time, but I cannot find it now. The problem here is that I am making a service that needs to persist the Powerpoint after every change (e.g.: after I append one slide or change a text), so I don't know what can I do or if you can provide a workaround for that. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
