POEclipse RCP/ Plug-in Question
text
Body
copied!<p>I have an RCP application (referred to as RCP-APP). I have created a new plug-in (referred to as plug-in A) that wraps a media player api (.jar file) and a folder of C libraries (dlls) that the media player api accesses via JNA. I then created another plugin (referred to as plug-in B) that contains a media player application that depends on Plug-in A. </p> <p>When plug-in B is activated I get the following error messages informing me that Plug-in B cannot find the media player .dlls it is looking for:</p> <pre> !ENTRY org.eclipse.jface 4 2 2009-06-22 10:05:22.475 !MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.jface". !STACK 0 java.lang.UnsatisfiedLinkError: Unable to load library 'libvlc': The specified module could not be found. at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:114) at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:157) at com.sun.jna.Library$Handler.(Library.java:123) at com.sun.jna.Native.loadLibrary(Native.java:260) at com.sun.jna.Native.loadLibrary(Native.java:246) at org.videolan.jvlc.internal.LibVlc.(LibVlc.java:41) at org.videolan.jvlc.JVLC.(JVLC.java:45) at com.bah.gs.arts.jekyll.plugins.videolog.VideoLogDisplay.displayStream(VideoLogDisplay.java:32) at com.bah.gs.arts.jekyll.core.extensionpoints.DisplayStreamFactory.getDisplayStreams(DisplayStreamFactory.java:57) at com.bah.gs.arts.jekyll.core.views.medialist.MediaListView$1.doubleClick(MediaListView.java:91) at org.eclipse.jface.viewers.StructuredViewer$1.run(StructuredViewer.java:799) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:37) at org.eclipse.core.runtime.Platform.run(Platform.java:880) at org.eclipse.ui.internal.JFaceUtil$1.run(JFaceUtil.java:48) at org.eclipse.jface.util.SafeRunnable.run(SafeRunnable.java:175) at org.eclipse.jface.viewers.StructuredViewer.fireDoubleClick(StructuredViewer.java:797) at org.eclipse.jface.viewers.AbstractTreeViewer.handleDoubleSelect(AbstractTreeViewer.java:1419) at org.eclipse.jface.viewers.StructuredViewer$4.widgetDefaultSelected(StructuredViewer.java:1173) at org.eclipse.jface.util.OpenStrategy.fireDefaultSelectionEvent(OpenStrategy.java:237) at org.eclipse.jface.util.OpenStrategy.access$0(OpenStrategy.java:234) at org.eclipse.jface.util.OpenStrategy$1.handleEvent(OpenStrategy.java:295) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1003) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3823) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3422) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2384) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2348) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2200) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:495) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:288) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:490) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at com.bah.gs.arts.jekyll.core.Application.start(Application.java:20) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:193) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:386) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:549) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:504) at org.eclipse.equinox.launcher.Main.run(Main.java:1236) at org.eclipse.equinox.launcher.Main.main(Main.java:1212) </pre> <p><strong>How do I inform Plug-in B (or the RCP-APP) that the .dlls are in a specific folder in Plug-in A</strong>?</p> <p>It appears that the api expects to find the .dlls via it's environment PATH variable.</p> <p><strong>How can I essentially communicate "plug-in A/Folder-Name"</strong>?</p> <p>Thanks for your assistance.</p>
