Get Url of a file uploaded by a Java Servlet

Hello everybody,

I'm working with CKEditor and I have the following problem.

In order to insert an image on my local machine into the text editor, I need first to upload the image to the server, then get back its url.

As I'm working with Java Servlet, my code is as follow :

CKEDITOR.replace(this.rteid, {
filebrowserImageBrowseUrl : '/ckfinder/ckfinder.html?Type=Images',
filebrowserImageUploadUrl : 'TransfertServlet'
});

it means when I click the button "Upload it to server", the Java Servlet named "TransfertServlet" is called.

My question is : how can i send back the url of the image so that I can insert it to my text ?

Thank you for your help !

In the resulting HTML generated by your servlet.. i believe you will need to call a Javascript function in ckeditor. The call would look something like this:

window.opener.CKEDITOR.tools.callFunction( funcNum, fileUrl [, data] );

An example would be:

// Helper function to get parameters from the query string.
function getUrlParam(paramName)
{
  var reParam = new RegExp('(?:[\?&]|&amp;)' + paramName + '=([^&]+)', 'i') ;
  var match = window.location.search.match(reParam) ;
 
  return (match && match.length > 1) ? match[1] : '' ;
}
var funcNum = getUrlParam('CKEditorFuncNum');
var fileUrl = '/path/to/file.txt';
window.opener.CKEDITOR.tools.callFunction(funcNum, fileUrl);
//

Thank you for your answer.

In fact, your code doesn't work as is, because of this line :

*** window.opener.CKEDITOR.tools.callFunction(funcNum, fileUrl);

I've changed it to

*** window.parent.CKEDITOR.tools.callFunction(funcNum, fileUrl);

and it worked !

Thanks

Awesome. Glad it worked for you. The window.parent is usually used in Frames. window.opener is used with popup windows.
