I have an RCP application that I have attached my help plugin to. Help opens when I click Open Help, then a new window opens with the help. Is there a way to make my help plugin open in a browser window?

My help plugin.xml code:

<?xml version="1.0"?>
<plugin>
   <extension
         point=".eclipse.help.toc">
         <toc file="toc_Concepts.xml" />
         <toc file="toc_Ref.xml" />
         <toc file="toc_Tasks.xml" />
      <toc
            file="toc.xml">
      </toc>
      <toc
            file="testToc.xml"
            primary="true">
      </toc>
   </extension>
      <extension
         point=".eclipse.ui.menus">
      <menuContribution
            locationURI="menu:.eclipse.ui.main.menu">
         <command
               commandId=".eclipse.ui.help.displayHelp"
               label="Open Help"
               tooltip="Open the Eclipse Help System">
         </command>
      </menuContribution>
   </extension>
</plugin>
