------------------------------------------------------------ -----------
In the manifest file the bundle activator is
Bundle-Activator: SampleRCP.SampleRCPApplication

This is the Plugin.xml
===========================================================
<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>
<plugin>

<extension
id="application"
point="org.eclipse.core.runtime.applications">
<application>
<run
class="SampleRCP.SampleRCPApplication">
</run>
</application>
</extension>
<extension
point="org.eclipse.ui.perspectives">
<perspective
name="SampleRCP Perspective"
class="SampleCP.Perspective"
id="Sample.perspective">
</perspective>

</extension>

<extension
point="org.eclipse.ui.editors">
<editor
default="true"
class="simple.display.editor.SimpleDisplayEditor"
icon="icons/demo.gif"
name="SampleDisplayEditor"
id="sample.display.editor.SampleDisplayEditor"
extensions="yiq"/>
</extension>

</plugin>
===========================================================
2)I have made a plugin which is having ediotrs,views,perspectives.
How do i add this plugin in RCP application.
I have added this pulgin from the Dependencies tab in to the RCP.But when
i launch this RCP i can only see various views and perspectives.The
editors does not show up.
What can be the possible mistake or reasons.

Thanking in advance for any help and answers.

Look in your runtime workspace .log file. There are probably messages
about not being able to find certain plugins.

When you launch an RCP app, it fills in the launch config with some
plugins. If you then include other plugins in your plugin dependencies
you need to go to the launch config and add required plugins.

Oh, make sure that your bundle activator is not the same class as your
application.

You said SampleRCP.SampleRCPApplication is your bundle activator AND
SampleRCP.SampleRCPApplication is your application class.

Generate any template sample plugin to find out what your plugin class
(bundle activator) should look like.
