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" ;
   • }
2. 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
3. Add in web.xml the declaration of the servlet
   • <servlet>
     • <servlet-name>AddEventMenuServlet?</servlet-name>
     • <servlet-class>servlets.AddEventMenuServlet?</servlet-class>
     • </servlet>
     • <servlet-mapping> <servlet-name>AddEventMenuServlet?</servlet-name>
     • <url-pattern>/AddEventMenuServlet?</url-pattern>
     • </servlet-mapping>
4. Create directory & file for servlet ( /hvp_pilot/handwritten/java/servlets/SearchJsonServlet.java )
5. 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???
6. What about throws ServletException, IOException....?
7. What about doGet & doPost? ​http://www.molgenis.org/browser/molgenis2_test/src/handwritten/RESTServlet.java?rev=1473
