I have an application based upon the NetBeans platform. When I click the "Show as HTML" button, no browser opens: nothing happens. I created an empty NetBeans platform-based application from the wizard, and I get the same result. The IDE log shows this error: INFO [org.netbeans.core.NbURLDisplayer]: showing: nbfs://nbhost/SystemFileSystem/shortcuts.html java.io.IOException: Failed to open nbfs://nbhost/SystemFileSystem/shortcuts.html. Error message: Access is denied. at sun.awt.windows.WDesktopPeer.ShellExecute(WDesktopPeer.java:77) at sun.awt.windows.WDesktopPeer.browse(WDesktopPeer.java:70) at java.awt.Desktop.browse(Desktop.java:386) [catch] at org.netbeans.core.NbURLDisplayer$DesktopBrowser$1.setURL(NbURLDisplayer.java:243) at org.netbeans.core.NbURLDisplayer$DesktopBrowser$1.reloadDocument(NbURLDisplayer.java:252) at org.openide.awt.HtmlBrowser$1URLSetter.run(HtmlBrowser.java:481) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:251) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:727) at java.awt.EventQueue.access$200(EventQueue.java:103) at java.awt.EventQueue$3.run(EventQueue.java:688) at java.awt.EventQueue$3.run(EventQueue.java:686) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.awt.EventQueue.dispatchEvent(EventQueue.java:697) at org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:159) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:242) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:161) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:150) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:146) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:138) at java.awt.EventDispatchThread.run(EventDispatchThread.java:91) This button works when I use the same button in the NetBeans IDE itself. Maybe my NetBeans platform application would need to include more modules for this button to work? It might not be the solution: I want to keep the number of NetBeans modules to a minimum. While the "Show as HTML" is a great option, it should not show if the configuration doesn't allow a correct execution. No matter what, the button should display an error message when an error happens rather than silently ignoring it or just logging the error. In my case,it would be simpler to not display that button at all than support users who might have configuration issues. A simple way to do this would be to check for the value of KeymapPanel.btnPrintAsHTML.text in the branding. If the value is empty, then don't display that button.
My workaround has been to add the following modules to my app: "External Execution API" "External Execution Implementations" "External HTML Browser"
re-assigning to proper component. Please evaluate. Thank you
Adding a dependency on "IDE" modules came with their own issues. The solution I actually ended up using is to make the button invisible using reflection, and plugging my own options controller.
Enhancement; I slightly improved URL generation, so it could work in your app. If not, you may use -J-Dorg.netbeans.modules.options.keymap.ExportShortcutsAction.disable=true to remove the button from the dialog layout. Implemented in jet-main#f2bb697b5054
Integrated into 'main-silver', will be available in build *201508050002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-silver/rev/f2bb697b5054 User: Svata Dedic <sdedic@netbeans.org> Log: #253085: URL changed to EXTERNAL using URLMapper since external browser is opened anyway. Show as HTML can be disabled by system property
