Re: [dtp-dev] Overriding icons using labelService extension point

[Lawrence E Dunnell <ledunnel@xxxxxxxxxx>]

The icon location is specified as "icons/view.png"
which doesn't exist when the plug-in is deployed because the deployed plug-in
is a single file called oracle.dbtools.connectivity_1.0.0.jar.
 In order to get Eclipse to look for the icons inside the jar file
you must specify the icon location as:

iconLocation = "platform:/plugin/oracle.dbtools.connectivity/icons/dbconn.png"

Thanks Larry.

But now I am hit with another hiccup.

I have an icons directory in the plugin jar with PNG images for DSE 
icons and I have them spec'd in the plugin.xml. It works fine when I run
test the plugin within the Eclipse IDE; but fails when run standalone 
with following exception in the org.eclipse.ui.workbench/log file.

Caused by: java.io.FileNotFoundException: file:/home/anthos/projects/opensource/eclipse-platform/plugins/oracle.dbtools.connectivity_1.0.0.jar!/icons/dbconn.png

extension point in plugin.xml:-
   <extension point =

                <contributor
                    
   type =

   iconLocation = "icons/view.png"
                    
   displayType = "MaterializedView">

   type =

   iconLocation = "icons/view.png"
                    
   displayType = "View">
                </contributor>

   iconLocation = "icons/plsql_package.png"
                    
   displayType = "Package">

        </extension>

Any clue ?
