Sometimes getting NullPointer exception when clicking "Find" [main class in JDBC driver], but even when I click Find and there are no exceptions, I click OK and driver is not getting added. java.lang.NullPointerException at javax.swing.plaf.basic.BasicProgressBarUI.updateS izes(BasicProgressBarUI.java:433) at javax.swing.plaf.basic.BasicProgressBarUI.getBox (BasicProgressBarUI.java:375) at com.sun.java.swing.plaf.windows.WindowsProgressBa rUI.paintIndeterminate (WindowsProgressBarUI.java:142) at javax.swing.plaf.basic.BasicProgressBarUI.paint (BasicProgressBarUI.java:333) at javax.swing.plaf.ComponentUI.update (ComponentUI.java:142) at javax.swing.JComponent.paintComponent (JComponent.java:541) at javax.swing.JComponent.paint (JComponent.java:808) at javax.swing.JComponent.paintChildren (JComponent.java:647) at javax.swing.JComponent.paint (JComponent.java:817) at javax.swing.JComponent.paintWithOffscreenBuffer (JComponent.java:4787) at javax.swing.JComponent.paintDoubleBuffered (JComponent.java:4740) at javax.swing.JComponent._paintImmediately (JComponent.java:4685) at javax.swing.JComponent.paintImmediately (JComponent.java:4488) at javax.swing.RepaintManager.paintDirtyRegions (RepaintManager.java:410) [catch] at javax.swing.SystemEventQueueUtilities$ComponentWo rkRequest.run(SystemEventQueueUtilities.java:117) at java.awt.event.InvocationEvent.dispatch (InvocationEvent.java:178) at java.awt.EventQueue.dispatchEvent (EventQueue.java:454) at java.awt.EventDispatchThread.pumpOneEventForHiera rchy(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEventsForHierarc hy(EventDispatchThread.java:151) at java.awt.EventDispatchThread.pumpEventsForHierarc hy(EventDispatchThread.java:141) at java.awt.Dialog$1.run(Dialog.java:540) at java.awt.Dialog.show(Dialog.java:561) at org.netbeans.core.windows.services.NbPresenter.su perShow(NbPresenter.java:722) at org.netbeans.core.windows.services.NbPresenter.do Show(NbPresenter.java:765) at org.netbeans.core.windows.services.NbPresenter.ru n(NbPresenter.java:753) at org.openide.util.Mutex.doEventAccess (Mutex.java:924) at org.openide.util.Mutex.readAccess (Mutex.java:158) at org.netbeans.core.windows.services.NbPresenter.sh ow(NbPresenter.java:738) at org.netbeans.modules.db.explorer.actions.AddDrive rAction.performAction(AddDriverAction.java:103) at org.openide.util.actions.NodeAction$3.run (NodeAction.java:440) at org.openide.util.actions.CallableSystemAction.doP erformAction(CallableSystemAction.java:116) at org.openide.util.actions.NodeAction$DelegateActio n.actionPerformed(NodeAction.java:438) at javax.swing.AbstractButton.fireActionPerformed (AbstractButton.java:1786) at javax.swing.AbstractButton$ForwardActionEvents.ac tionPerformed(AbstractButton.java:1839) at javax.swing.DefaultButtonModel.fireActionPerforme d(DefaultButtonModel.java:420) at javax.swing.DefaultButtonModel.setPressed (DefaultButtonModel.java:258) at javax.swing.AbstractButton.doClick (AbstractButton.java:289) at javax.swing.plaf.basic.BasicMenuItemUI.doClick (BasicMenuItemUI.java:1113) at javax.swing.plaf.basic.BasicMenuItemUI$MouseInput Handler.mouseReleased(BasicMenuItemUI.java:943) at java.awt.Component.processMouseEvent (Component.java:5100) at java.awt.Component.processEvent (Component.java:4897) at java.awt.Container.processEvent (Container.java:1569) at java.awt.Component.dispatchEventImpl (Component.java:3615) at java.awt.Container.dispatchEventImpl (Container.java:1627) at java.awt.Component.dispatchEvent (Component.java:3477) at java.awt.LightweightDispatcher.retargetMouseEvent (Container.java:3483) at java.awt.LightweightDispatcher.processMouseEvent (Container.java:3198) at java.awt.LightweightDispatcher.dispatchEvent (Container.java:3128) at java.awt.Container.dispatchEventImpl (Container.java:1613) at java.awt.Window.dispatchEventImpl (Window.java:1606) at java.awt.Component.dispatchEvent (Component.java:3477) at java.awt.EventQueue.dispatchEvent (EventQueue.java:456) at java.awt.EventDispatchThread.pumpOneEventForHiera rchy(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEventsForHierarc hy(EventDispatchThread.java:151) at java.awt.EventDispatchThread.pumpEvents (EventDispatchThread.java:145) at java.awt.EventDispatchThread.pumpEvents (EventDispatchThread.java:137) at java.awt.EventDispatchThread.run (EventDispatchThread.java:100) Rebooting, reinstalling NetBeans didn't help. It all started after I added a few drivers successfully, but it geve me error something like "not enough information" with a bunch of empty [],(), etc. Then I put JDBC driver inside NetBeans [/lib/ext] and added it successfully, but it was connecting to some unknown database ;-0 So we removed all JDBC drivers from the list including a bridge one. And I was never able to add JDBC driver to NetBeans again.

I am having this same issue, except... I sware when I installed 3.6 I was able to install JDBC drivers. I am using Oracle and Informix. I had some other problems so I re-installed, asfter wiping all files. I am CERTAIN I am attempting to load the correct JDBC drivers, Oracle 1.2 file classes1.2.jar. NetBeans finds th correct class and everything, but when I click "OK" the driver doesn't get loaded. rrbrandt@aep.com
Reassigning to db module.
It looks like a duplicase of the issue #38385. *** This issue has been marked as a duplicate of 38385 ***
Yes seems like a dup
