I’m working on a JSF 2.0 web app, and I’m having trouble passing in a String composed of different words separated by a ‘|’ to jQuery’s AutoComplete using a servlet. It works great in IE, but seems to fail retrieving any data in Firefox.

$(document).ready(function(){
//var availableTags = "yes|maybe|no".split('|');
$.ajax({
type: 'POST',
cache: 'false',
data: 'codeType=allergyList',
url: '/miloWeb/Autocomplete',
async: false,
success: function(data){
availableTags = data.split('|');
},
error: function (xhr, ajaxOptions, thrownError){
alert(ajaxOptions);
}
});
$("#pAllergy").autocomplete({
source: availableTags
});
});
</script>
</ui:define>
<ui:define name="content">
<h2>Allergy List</h2>
<div>
<center>
<br />
<br />
<h:outputText styleClass="description" for="pAllergy">Allergy: </h:outputText>
<h:inputText id="pAllergy" value="#{allergyListBB.allergyList.allergy}" size="30"></h:inputText>
</tr>
<tr>
<td><button onclick="return false;" id="addAllergy">Add</button> </td>
</tr>
</table>
</center>
<h:inputHidden id="delId" value="#{allergyListBB.rowId}"></h:inputHidden>
</div>
</ui:define>
What this last part of code is doing is going into my Servlet and retrieving from the DB a string (i.e. cheese|chocolate|chery|chestnut| ) which then goes into the variable availableTags which is what we pass into the autocomplete.
My servlet looks like this:
package com.bravo.servlets;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.bravo.codeMaster.codeMaster;
import com.bravo.dropdowns.codeMedicationList;
/**
* Servlet implementation class Autocomplete
*/
@WebServlet("/Autocomplete")
public class Autocomplete extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public Autocomplete() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
response.getOutputStream().print("Unauthorized Access.");
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String codeType = request.getParameter("codeType");
response.getOutputStream().print(codeMaster.getStringList(codeType));
// This might as well be "response.getOutputStream().print("one|two|three|")
// for testing purposes, just to make sure it's returning something.
}
}
XTRA COMMENTS: It seems to me that if I set the variable availableTags to any string of strings, the moment I set the $(“#pAllergy”).autocomplete(), I can’t change it. so I need to get the correct string from the Servlet. Please help me out I can’t seem to figure out why it fails in Firefox and not in IE. I greatly appreciate the help!
You forgot to set the HTTP
Content-Typeresponse header in the servlet. Assuming that it’stext/plain, you need to add the following line before you write any bit to the response:This way jQuery can do its “intelligent guess” properly.
