Add a template variable${clipboard}. This replaces whatever the text content the clipboard contains. Here is the scenario:

I have a long complex URL in the clipboard that was copied from the browser's address bar. 


Then I could define a templatte like this:

template name: hyperlink
template pattern:

<a href="${clipboard}" target="_blank">${cursor}</a>


[For simplicity let us assume I had a "http://www.google.com" in the clipboard]
Now when I invoke the template I get:
 
<a href="http://www.google.com" target="_blank">|</a>

where | shows the cursor position.

Here is the implementation of template variable resolver for ${clipboard}:

package somepackage;

import org.eclipse.jface.text.templates.TemplateContext;
import org.eclipse.jface.text.templates.TemplateVariableResolver;
import org.eclipse.swt.dnd.Clipboard;
import org.eclipse.swt.dnd.TextTransfer;
import org.eclipse.ui.PlatformUI;

public class ClipboardVariableResolver extends TemplateVariableResolver {

	protected String resolve(TemplateContext context) {
		Clipboard clipboard = new Clipboard(PlatformUI.getWorkbench()
				.getActiveWorkbenchWindow().getShell().getDisplay());
		Object content = clipboard.getContents(TextTransfer.getInstance());
		if (content != null) {
			return (String) content;
		}
		return getType();
	}

}

and the extension:

   <extension
         point="org.eclipse.ui.editors.templates">
      <resolver
            class="somepackage.ClipboardVariableResolver"
            contextTypeId="java"
            description="Resolves to the content of the clipboard."
            icon="icons/clipboard.gif"
            name="clipboard content"
            type="clipboard">
      </resolver>
   </extension>
