Como faço pra alterar um arquivo xls que esteja com programação vb abilitada ou seja uma planilha dinamica com jxl-java. Consegui alterar dados dentro de uma planilha normal que não esteja com macro, porem quando vou tentar alterar uma planilha que tenha macro com mesma estenção ocorre o seguinte problema : Warning: Usage of a local non-builtin name Warning: MS Office Drawing Object on sheet "Teste" not supported - omitting Warning: escher atom getData called on object of type jxl.biff.drawing.EscherAtom code 0 Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at jxl.biff.DVParser.<init>(DVParser.java:669) at jxl.biff.BaseCellFeatures.getDVParser(BaseCellFeatures.java:501) at jxl.write.biff.SheetWriter.writeDataValidation(SheetWriter.java:1137) at jxl.write.biff.SheetWriter.write(SheetWriter.java:581) at jxl.write.biff.WritableSheetImpl.write(WritableSheetImpl.java:1558) at jxl.write.biff.WritableWorkbookImpl.write(WritableWorkbookImpl.java:950) at CONDIFSYS.Teste.Escreve_e_Fecha_o_arquivo(Teste.java:49) at CONDIFSYS.Teste.jButton1ActionPerformed(Teste.java:113) at CONDIFSYS.Teste.access$000(Teste.java:19) at CONDIFSYS.Teste$1.actionPerformed(Teste.java:86) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:1995) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2318) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:387) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:242) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener.java:236) at java.awt.Component.processMouseEvent(Component.java:6263) at javax.swing.JComponent.processMouseEvent(JComponent.java:3267) at java.awt.Component.processEvent(Component.java:6028) at java.awt.Container.processEvent(Container.java:2041) at java.awt.Component.dispatchEventImpl(Component.java:4630) at java.awt.Container.dispatchEventImpl(Container.java:2099) at java.awt.Component.dispatchEvent(Component.java:4460) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4574) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4238) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4168) at java.awt.Container.dispatchEventImpl(Container.java:2085) at java.awt.Window.dispatchEventImpl(Window.java:2478) at java.awt.Component.dispatchEvent(Component.java:4460) at java.awt.EventQueue.dispatchEvent(EventQueue.java:599) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:269) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:184) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:174) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:169) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:161) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122)
