== HVP pilot add functionality (build servlet in molgenis) ==
In order to proper present your data from a javascript call (in a plugin) you need a servlet :

 1. Add in model the function :
   * * public String getCustomHtmlHeaders()
   * {
   * return "<script src=\"res/scripts/lib.js\" language=\"javascript\"></script>\n" +
   * "<script src=\"Prototype/prototype.js\" language=\"javascript\"></script>\n" ;
   * 
   * }
 1. Place the javascript file in the referred  location. In the ftl file call the function as  onclick="!RestJsonDatafromOntocat(InputTerm)" not as onclick="!__action.value='SubmitTerm' . The second is used for function inside the model.
   * Arguments from the .ftl file can be reached through arguments
 1. Add in web.xml the declaration of the servlet
   * <servlet>
     * <servlet-name>AddEventMenuServlet</servlet-name>
     * <servlet-class>servlets.[wiki:AddEventMenuServlet]</servlet-class>
     * </servlet>
     * <servlet-mapping> <servlet-name>AddEventMenuServlet</servlet-name>
     * <url-pattern>/AddEventMenuServlet</url-pattern>
     * </servlet-mapping>
 1. Create directory & file for servlet ( /hvp_pilot/handwritten/java/servlets/SearchJsonServlet.java )
 1. Incude the necessary :
   * * package servlets;
   * 
   * import java.io.IOException;
   * import java.io.!PrintWriter;
   * 
   * import javax.servlet.!ServletException;
   * import javax.servlet.http.!HttpServletRequest;
   * import javax.servlet.http.!HttpServletResponse;
   * 
   * import org.apache.log4j.Logger;
   * import org.molgenis.util.!HttpServletRequestTuple;
   * import org.molgenis.util.Tuple;
     * '''__IS this the minimum/optimal set???__'''
