HTML generated by PLSQL not working when migrating from 9i to 10g

Question

Hello everybody,
We migrated a 9i database (web+application server on Windows) to 10gR2 (web+application server on Linux). The database contains a package that dynamically generates HTML and JSP tags .
Problem: the HTML code generated in 10g by the package is different by the HTML code generated in 9i. The package generating the html in 10g is identic, equal with the package generating html in 9i. We also receive a the following message error in 10g when loading the web page in 10g:
" 'Style' is null or undefined". It seems there is a problem with the Style object.
Anybody has seen something similar, because I am not very familiar with HTML and JSP.
Any help will be appreciated.
Thank you, Daniela.

Thank you for your reply.
Yes, it's done using MOD-PLSQL version 10.1.2.0.2.
I did as you said: compared the 2 generated HTML files. It's not that it doesn't generate all tags. It generates all tags but some of them are different, that is it screws them up.
Here it is some example code.
For example, in 9i I have the following code:
div id=div_plus_GENERALE style="cursor:hand; display:none;"
<td> width=8 </td>
<td id=butt align=left style="font-family:Verdana,Tahoma;
font-size: 10px; font-weight: 400; color: '#ffffff';
background-color: '';
"onClick="if (butt_clicked) butt_clicked.style.cssText=restore_butt_style;
butt_clicked=this; restore_butt_style=butt_off_lit;
this.style.cssText=butt_on_lit;
var x = document.getElementById('Freccia_' + freccia_old);
x.style.display = 'none';
Freccia_sitointer_anagrafica_anagrafica_cliente_punto.style.display='block';
freccia_old='sitointer_anagrafica_anagrafica_cliente_punto';"
onMouseOver="this.style.cssText=butt_on_lit;"
onMouseOut="if (butt_clicked != this) this.style.cssText=butt_off_lit;">Anagrafica Fornitura</td></tr>
<tr>
<td height=2></td>
</tr>
</table>
In 10g the HTML code looks like this:
div id=div_plus_GENERALE style="cursor:hand;"
<td width=8> </td>
<td align=left style="font-family:Verdana,Tahoma;
font-size: 10px; font-weight: 400; color: '#ffffff';
background-color: '';">
<a href="sitointer.anagrafica.anagrafica_cliente_punto target="frameCenter"
onClick="var x = document.getElementById('Freccia_' + freccia_old);
x.Style.visibility='hidden';
Freccia_sitointer_anagrafica_anagrafica_cliente_punto.Style.visibility='visible';
freccia_old='sitointer_anagrafica_anagrafica_cliente_punto';"
onMouseOver="this.style.cssText=butt_on_lit;"
onMouseOut="if (butt_clicked != this) this.style.cssText=butt_off_lit;">Anagrafica Fornitura</a></td></tr>
<tr>
<td height=2></td>
</tr>
</table>
At this point I don't know what should I investigate next.
Thank you very much.
Daniela
