When I ask to the OSGi container to launch my service, libraries are loaded, objects are instantiated, but as soon as I ask a rendering (using vtkPanel::Render() ) I get this error "Invalid memory access of location 0x0 rip=0x10109cdcc" which looks like a null pointer exception...</div><div> </div><div> For a debugging purpose, I have made a copy/paste of vtkPanel class into MyVtkPanel (which is in my application package) and replace the vtkPanel by MyVtkPanel into my small test application. I expected no change in the resulting behaviour, instead I have an unsatisfied link error on RenderCreate() method.</div><div>This method is declared as native, but my DYLD_LIBRARY_PATH points to the VTK libs. I thought it should have found this method....</div><div><br></div><div>Does someone has an idea of why this error occurs, is there some access restriction due to the class location (which is the only change... I guess...) ?</div><div><br></div><div>to summarise:</div><div>vtkPanel panel = new vtkPanel()</div><div>panel.Render()</div><div>works fine</div><div> </div><div><div>vtkPanel panel = new vtkPanel()</div><div>panel.Render()</div><div>leads to "<span class="Apple-style-span" style="color: rgb(222, 42, 0); font-family: Monaco; font-size: 11px; ">Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: test.vtk.impl.MyVtkPanel.RenderCreate(Lvtk/vtkRenderWindow;)I</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 11px/normal Monaco; color: rgb(222, 42, 0); "><span class="Apple-tab-span" style="white-space:pre"> </span>at test.vtk.impl.MyVtkPanel.RenderCreate(<span style="text-decoration: underline ; color: #121f8f">Native Method</span>)<span class="Apple-style-span" style="color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; ">"</span></div></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 11px/normal Monaco; color: rgb(222, 42, 0); "><span class="Apple-style-span" style="color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; "><br></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 11px/normal Monaco; color: rgb(222, 42, 0); "><span class="Apple-style-span" style="color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; "><br></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 11px/normal Monaco; color: rgb(222, 42, 0); "><span class="Apple-style-span" style="color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; "><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 11px/normal Monaco; "><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 11px/normal Monaco; ">>nm libvtkRenderingJava.dylib | grep RenderCreate</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 11px/normal Monaco; ">0000000000047b9b T _Java_vtk_vtkPanel_RenderCreate</div><div><br></div><div>Tested under Mac OSX snow leopard with VTK 5.40, 5.6.0 and 5.6.1</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>Regards,</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>JeT</div><div><br></div><div>PS: if someone has some experience with VTK + OSGi, some tips would be of great help.
