Eclipse Plugin Creation - "Plug-in name was unable to load class " error

Question

Hi everybody and happy new year to you all,
i got a little problem again. I have written the first lines of code of my plugin and wanted to test it (run as Eclipse Application). I got the following error-msg, when clickin either on the menu item or toolbar button:
"Could not create action delegate for id: org.eclipse.tui.inpulse.actions.InpulseStart
Reason:
Plug-in org.eclipse.tui.inpulse was unable to load class org.eclipse.tui.inpulse.InpulseStart."
My project has the following properties (of which i read they are important):
Source folder: org.eclipse.tui.inpulse/src
Output folder: org.eclipse.tui.inpulse/bin
Dependencies: org.eclipse.ui, org.eclipse.core.runtime
Extensions: org.eclipse.ui.actionSets
ExtensionsPoints: none
The following is my plugin xml:
<plugin>
   <requires>
          <import plugin="org.eclipse.core.resources"/>
        <import plugin="org.eclipse.ui"/>
    </requires>
    <runtime>
          <library name="Inpulse.jar"/>
    </runtime>
    <extension
          id="org.eclipse.tui.inpulse.InpulseActionSet"
          name="org.eclipse.tui.inpulse.InpulseActionSet"
          point="org.eclipse.ui.actionSets">
        <actionSet
            id="org.eclipse.tui.inpulse.InpulseActionSet"
            label="Inpulse"
              visible="true"
         description="The action set for the Eclipse Hello World example">
         <menu id="org.eclipse.tui.inpulse.InpulseMenu" label="Inpulse">
               <separator name="samples"/>
         </menu>
         <action id="org.eclipse.tui.inpulse.actions.InpulseStart"
               menubarPath="org.eclipse.tui.inpulse.InpulseMenu/samples"
               toolbarPath="Normal"               
               label="Inpulse"
               tooltip="Start pattern search."
               class="org.eclipse.tui.inpulse.InpulseStart"/>
        </actionSet>
   </extension>
</plugin>The javafile "InpulseStart.java" is in the "org.eclipse.tui.inpulse" package and has the first line "package org.eclipse.tui.inpulse;". The class "InpulseStart" implements "IWorkbenchWindowActionDelegate".
So the following members are implemented:
public void run(IAction proxyAction){...};
public void selectionChanged(IAction proxyAction, ISelection selection){...};
public void dispose(){...};
//and some additional ones ;-)I really dont know what i do wrong. If you have an idea, what i just miss out or do wrong, id be glad if you helped me out!

Aye, you are right, i should/could have posted this somewhere else. I just hoped, that i can get a good answer here, cause ppl helped me out very nice before.
Im sorry if i offended users of this forum...
The "advice" is recognized and i will post somewhere else in case i have a eclipse specific problem.
