Server side script not running on stand-alone XE

Question

Hello,
In my application I created a Server side script (AJAX) which presents a select-list based on other fields on the page. The very same application runs on a 10g+APEX3.0.1 database AND on a standard XE+APEX2.1 database, which are both accessed via a HTTP-server. The application with the script runs fine on this platform (XP).
I have two other XP-machines on which I also installed XE+APEX2.1. Both are stand-alone versions NOT accessed via a HTTP-server. I installed exactly the same application which runs on the platform with HTTP server on both of the machines. While testing the correct functioning, I noticed that everything works ok, EXCEPT the server side script which gives me a better select list. Instead of this I get the old-fashioned version of the select-list which is not able to use the value elsewhere on the page.
I found a similar problem on the XE forum (Re: Server side scripts features ) but it doesn't answer my question how to get the script working on a standalone version of XE (= without access via a HTTP-server).
Can anybody please help me?
Thanks & regards,
Jan.

Carl,
Thanks for your suggestion to install FireFox and the Firebug tool (which I wasn't aware of).
After having looked at the problem for hours, I found what I think is the problem: the htmldb_html_elements.js script.
As already mentioned, the properly functioning XE on my local PC is accessed via a HTTP-server, as well as the 10gR2+APEX3.0.1 version also running on that PC.
On the laptop, not running HTTP-server, I get the message: <br>
<FONT COLOR="RED">$x is not defined <BR>
<FONT COLOR="BLUE"> f_21_select_kpn<FONT COLOR="RED">(<FONT COLOR="BLUE">input<FONT COLOR="BLACK">#P21_GBREKNR 405<FONT COLOR="RED">, "P21_KOSTENPOST") <BR>
<FONT COLOR="BLUE">onblur<FONT COLOR="RED">(<FONT COLOR="BLACK">blur <FONT COLOR="RED">)
</FONT><BR>
That is in the 'Console' of Firebug.
When changing to Script I do see a remarkable difference.
On the PC there the following text is found in the first lines of htmldb_html_elements.js:
/*htmld_elements will contain the lower level html access js*/<br>
var gDebug = true;<br>
var gkeyPressTime;<br>
var gLastTab=false;<br>
var gRegex=false;<br>
var ie=(document.all)?true:false;<br>
if(ie){document.expando=true;}<br>
var gDebugWindow = false;<br>
/*<br>
$x functions have to do with either single elements or array of elements<br>
$v functions have to have to do with manipulating values or interaction based off a value<br>
$xml function have to do with manipulating xml values<br>
$a functions are based on ajax<br>
$d functions are specific dhtml constructs<br>
*/<br>
/* begin $x functions */<br>
function $x(pNd){<br>
try{<br>
var node;<br>
...<br><br>
On the laptop however the first few lines are:<br><br>
/*htmld_elements will contain the lower level html access js*/<br>
<br>
var gDebug = true;<br>
var gkeyPressTime;<br>
var gLastTab=false;<br>
var gRegex=false;<br>
if(document.all){document.expando = true;}<br>
// Elements //<br>
<br>
function html_GetElement(pNd){<br>
try{<br>
var node;<br>
switch(typeof (pNd)){<br>
...<br><br>
I think that the difference is in these two scripts.
But why are the scripts different: it is the same XE that is installed on the laptop and the PC.<br>The answer I found in the images/javascript directory of APEX3.0.1 which is located in the APACHE directory-tree (you have to copy the images to APACHE when you use the HTTP-server). And indeed: the htmldb_html_elements.js has exactly the same text as what I see in Firebug on the PC. So XE on the PC is using the javascripts in the image-directory of APACHE on the PC and not the XE-version of the scripts, embedded in XE.
<br><br>
So the answer seems to be: copy the APEX3.0.1 versions of the script over to the PC and try to get them into the database. Or...???
<br>
Can it be loaded into the database? Will XE accept it?
<BR><br>
Would be nice to have answers if the conclusion I found is the right one and if it can be fixed by loading the js into XE.
<br>
Best regards and thanks for your help so far.
