Unable to connect to Portlet class from AJAX request .

[Ravi Kiran，修改在11 年前。]

Hi ,
I am using Liferay 6.1 CE for Portal Application development .
I am trying to Use Jquery with AJAX in my Portlet .
This is my JSP Page as shown :

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<portlet:defineObjects />

<script type="text/javascript">

$(document).ready(function(){

jQuery.ajax({
url:'<portlet:resourceURL id="ajax" ></portlet:resourceURL>',
data: {id:data},
type: 'POST',
datatype:'json',
success: function(respData) {
alert(respData);
}
});
});
</script>



This is my MVC Portlet class
public class ArrayPortlet extends MVCPortlet {

@Resource(name="ajax")
public void testAjax(
PortletConfig config, ResourceRequest request, ResourceResponse response)
throws Exception {


}
}


But i am unable to connect to my Java class .
Could somebody please help me . Thanks .

Can try it as href
<a href='<portlet:resourceURL>
<portlet:param name="vehicleId" value="${vehicleInfo.pk}" />
</portlet:resourceURL>'

This could tell you if the issue with ajax call firing issue or server side configuration issue.

Regards,
Nagendra

Hi Ravi,

According to my knowledge you can't use @Resource(name="ajax"). Because there are not parameter in TLD through which you can bind it to the controller.
You have to use the serveResource method only.

And also make the method name as serveResource.

Add more on my own comment.

Make in Controller method as :-

@Override
public void serveResource(final ResourceRequest resourceRequest,
final ResourceResponse resourceResponse) throws IOException, PortletException
{

}

I tried the following , but still i am unsuccessful .

This is my JSP Page :

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<portlet:defineObjects />

<portlet:actionURL name="User" var="UserURL"/>

<script type="text/javascript">

$(document).ready(function(){

jQuery.ajax({
url:'<portlet:resourceURL id="resourceURL" var="resourceURL" />',
data: {id:data},
type: 'POST',
datatype:'json',
success: function(respData) {
alert(respData);
}

});

});
</script>A

This is under Java :


package com;

import java.io.IOException;

import javax.portlet.PortletException;
import javax.portlet.ResourceRequest;
import javax.portlet.ResourceResponse;

import com.liferay.util.bridges.mvc.MVCPortlet;

public class Test extends MVCPortlet {



@Override
public void serveResource(final ResourceRequest resourceRequest,
final ResourceResponse resourceResponse) throws IOException, PortletException
{

System.out.println("Hi Madahava Rao");
}
}



Am i doing anythig wrong ??

Hello
Possibly the way you are passing url, that could be an issue.

I just tried to do the same and it works perfectly for me

My jsp:
"

<portlet:resourceURL id="postURL" var="postURL">
<portlet:param name="protocol" value="http"></portlet:param>
</portlet:resourceURL>


<input type='hidden' id='postURL' value='${postURL}'/>

"

My js:
"

function accessHttp(){
var ajaxData = {
inputURL : $("#httpURLInput").val()
};

var url = $("#postURL").val();
alert(url);
$.ajax({
url: url,
data: ajaxData
}).done(function() {
alert("done");
});
}

"

My Java:

public class ContentUploaderPortlet extends MVCPortlet{

@Override
public void serveResource(ResourceRequest request, ResourceResponse response) throws IOException,PortletException{
System.out.println("in hererererere");
String protocol = request.getParameter("protocol");
String url = request.getParameter("inputURL");
System.out.println("protocol is "+protocol+"---"+url);
}

}

Hi Ravi,

I checked implementing your code in my Project.

I found the problem is in your JAVAScript code that you had written. I now modified your code as below :-

<script type="text/javascript">

$(document).ready(function(){

$.ajax({                                       
url:'<portlet:resourceURL />',
data: {id:"f"},
type: 'POST',
datatype:'json',
success: function(respData) {
alert(respData);
}

});

});
</script>

The problem in your code is as below :-
1) use $ instead of jQuery in your ajax call.
2) data: {id:data}, you can't use data inside id, it's reserved word so. make it as data: {id:"f"}

Hope now it will solve your problem.

Thanks & Regards,
