Grails - J2ee integration
Hi All,
I wish to do very simple thing -
In one of the divs in a JSP of my existing J2ee application I wish to render a grails app(ajax based).I could achieve this by simply using an iFrame,but I dodnot wish to use it for performance reasons.Is there any other way out
Please note that the J2ee app and grails app are on 2 different servers.
Any pointers would be very helpful
Thanks In Advance
Regards,
Ruchi

Re: Grails - J2ee integration
You can do this asking via ajax to the grails app. But since apps are in different servers, you'll need to set up some apache in front of them, so the grails app have to respond in the same domain from the other one. otherwise you won't get this working (crossdomain vunerability).

Yes are doing ajax, but how can we render a gsp from a grails
app inside a div of a jsp f a j2ee app?

Re: Grails - J2ee integration
The Ajax call will only see the rendered html. The GSP is parsed an
server level, so you don't need to care about that.

Re: Grails - J2ee integration
You can also just fetch the generated webapp and pass the html to your
jsp page as a string.
http://www.javapractices.com/topic/TopicAction.do?Id=147This does give your server a performance hit every time the remote
page is accessed, but eliminates a lot of setup and deployment
problems.

This example would work only if the jsp and the gsp are in the
same domain ,but if they are not then how would this work??
i.e if the jsp is a different server and the grails app is on
some other one this won’t work rt???

Re: Grails - J2ee integration
You could have your JSP webapp act as a proxy, accepting an AJAX request from the browser, then making a request to the Grails webapp, processing the response and forwarding that back to the browser.
Browser -> J2EE app -> Grails app
Browser <- J2EE app <- Grails app
this would get complicated if it required any cookies for the interaction with the Grails app.

Re: Grails - J2ee integration
They don't have to be in the same domain. To this work on different
domains you should include the hostname on the url.
You should check JQuery and Prototype and maybe run a try?

It doesn’t work if they are in different domains.I am getting
the following exception even if my apps are running locally on my system but 2
differnt servers--
access to restricted uri denied code 1012

Re: Grails - J2ee integration
Hi,
My previous post was to answer,
"Can u give an example how I can embed the grails app in a jsp div
with ajax call u just mentioned?"
As others have mentioned the "Cross Domain With AJAX Issue" need to
be address to make it work.
I apologize for not answer Both of the questions.
I have a important meeting in a few days.
I will try write an workable example by the end of the week.
(I also need this in the near future)
Proposed solution from Google is like this (one out of many),
http://ajaxian.com/archives/jsonp-json-with-paddingHere is what I would do,
1. Create a Grails App to render JASONP instead of HTML
(// Check Grails Doc for Render as HTML/XML/JSON .....)
http://www.pathf.com/blogs/2008/02/grails-and-json/2. Rework Javascript using JSONP,
I have no specific one in mind, jQuery, Prototype, Dojo all seem ok
If any one has insight / suggestion / experience / recommendation,
I would love to hear it before I spend or waste too much time.
Feel free to send me mail off the list ...

Re: Grails - J2ee integration
I forgot the other javascript function:
function listProducts(datos){
var lst = datos. lst var max = lst.length
var table = $('#appengineData').html("<table id='productsContent'></table>").children('table')
for(var i=0; i<max;++i){
table.append("<tr class='prodcutOdd'></tr>")
var tr = $('#appengineData #productsContent tr:last-child')
tr.append("<td><IMMG class='tooltip' src='" + lst[i].imgSrc + "'/></td>")
tr.append("<td><em>" + lst[i].name + "</em></td>")
}
}
Notice the callback param in the url request.
I also forgot a line before the render in the controller:
map.put( 'lst', productInstanceList)
render "${' listProducts'}(${map as JSON})"
