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

[Anil T Samuel <anil.samuel@xxxxxxxxxx>]

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 (No such file or directory)
	at java.io.FileInputStream.open(Native Method)

	at org.eclipse.swt.internal.Compatibility.newFileInputStream(Compatibility.java:155)
	at org.eclipse.swt.graphics.ImageLoader.load(ImageLoader.java:153)
	... 67 more

The icons in jar file :-
[anthos@bilbo opensource]$ jar -tvf 
/home/anthos/projects/opensource/eclipse-platform/plugins/oracle.dbtools.connectivity_1.0.0.jar 
| grep icons

extension point in plugin.xml:-
  <extension point = 
"org.eclipse.datatools.connectivity.sqm.core.ui.labelService">
               <contributor
                       type = 
"oracle.dbtools.modelbase.db.MaterializedView"
                       iconLocation = "icons/view.png"
                       displayType = "MaterializedView">
               </contributor>
               <contributor
                       type = "oracle.dbtools.modelbase.db.DatabaseLink"
                       iconLocation = "icons/dbconn.png"
                       displayType = "DatabaseLink">
               </contributor>
                               <contributor
                       type = 
"oracle.dbtools.connectivity.catalog.OracleView"
                       iconLocation = "icons/view.png"
                       displayType = "View">
               </contributor>
                               <contributor
                       type = "oracle.dbtools.modelbase.db.OraPackage"
                       iconLocation = "icons/plsql_package.png"
                       displayType = "Package">
               </contributor>
       </extension>

Any clue ?
