possible conflict with AJAX

[Steve Renard]

I have a J2EE web application which performs database select, update and insert operations..
All the operations work fine after thorough testing.
But only in some cases, the update and insert operations take forever and just sit there doing nothing.
Interestingly, I don't get any exception or error in the logs..
But after some research, I was able to find something unusual.
I have AJAX calls inside my JSP's.
I suspect that whenever I trigger an update/insert operation before an AJAX response comes back, I run into this problem.
And I'm unable to perform any update/insert operation thereafter.
I'm not sure if the problem is because of AJAX conflict or something else..
Please suggest me..

And what does the code look like that you are using to make a call?

Here's the AJAX code:

  
var urel = "FSAction.do?todo=fetch";
var queryString = "&caseno="+caseno.value;
xmlHttpreq = new ActiveXObject("Microsoft.XMLHTTP");
xmlHttpreq.open("POST", urel, true);
xmlHttpreq.onreadystatechange = processStateChange;
xmlHttpreq.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;");
xmlHttpreq.send(queryString);

Well one thing is if you are doing post, you would not be using a querystring

var urel = "FSAction.do?todo=fetch";
var queryString = "&caseno="+caseno.value;

should probably be

var urel = "FSAction.do?todo=fetch";
var queryString = "caseno="+caseno.value;
 
or
 
var urel = "FSAction.do";
var queryString = "todo=fetch&caseno="+caseno.value;

If you were just using a querystring, you would be using get and append it to the url and put null in send.
