I am running a report from inside my application. When I run it from jBuilder it works perfectly. When I create an executable JAR it gives me an error (see below for stack trace). The line of code it errors on is :- JasperDesign jasperDesign = JRXmlLoader.load(reportFile); reportFile contans the name of the report to be run. Can anyone help ? org.apache.commons.logging.LogConfigurationException: java.lang.NullPointerException at org.apache.commons.logging.LogFactory.newFactory(LogFactory.java:558) at org.apache.commons.logging.LogFactory.getFactory(LogFactory.java:355) at org.apache.commons.logging.LogFactory.getLog(LogFactory.java:409) at org.apache.commons.digester.Digester.<init>(Digester.java:304) at net.sf.jasperreports.engine.xml.JRXmlDigester.<init>(JRXmlDigester.java:62) at net.sf.jasperreports.engine.xml.JRXmlDigesterFactory.createDigester(JRXmlDigesterFactory.java:957) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:203) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:168) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:152) at jController.T_Util.runJasperReport(T_Util.java:3895) at jController.T_Util.runReport(T_Util.java:3826) at jController.T_TableMaintenance.button_Click(T_TableMaintenance.java:3073) at jController.genericButton_Listener.actionPerformed(T_TableMaintenance.java:3423) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:1849) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2169) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:420) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:258) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener.java:234) at java.awt.Component.processMouseEvent(Component.java:5488) at javax.swing.JComponent.processMouseEvent(JComponent.java:3093) at java.awt.Component.processEvent(Component.java:5253) at java.awt.Container.processEvent(Container.java:1966) at java.awt.Component.dispatchEventImpl(Component.java:3955) at java.awt.Container.dispatchEventImpl(Container.java:2024) at java.awt.Component.dispatchEvent(Component.java:3803) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4212) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:3892) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:3822) at java.awt.Container.dispatchEventImpl(Container.java:2010) at java.awt.Window.dispatchEventImpl(Window.java:1766) at java.awt.Component.dispatchEvent(Component.java:3803) at java.awt.EventQueue.dispatchEvent(EventQueue.java:463) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:234) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:163) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:157) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:149) at java.awt.EventDispatchThread.run(EventDispatchThread.java:110) Caused by: java.lang.NullPointerException at org.apache.commons.logging.LogFactory.newFactory(LogFactory.java:543) ... 36 more Could not create the report java.lang.NullPointerException java.lang.NullPointerException
