Microsoft says you are putting script not in body but in td (Table Data)
element e.g.
var d =
document.createElement('div');
document.body.appendChild(d);
solution is to place the script outside the table to modify the body as seen
here
var d = document.createElement('div');
document.body.appendChild(d);
does this conform to your IE implementation?

Wow! When you say "embeds a Flash object within a JSP page", do you mean that your JSP generates a .swf document, or are you saying that the HTML your JSP generates causes a .swf document to be fetched by the browser? The difference is big: JSP was built to generate text-based content, not binary content. Yes, you /can/ trick it into generating binary content, but you have to be very careful. > All of this works > perfectly in Firefox but Internet Explorer exits with the error "Site > [mysite] cannot be loaded. Process terminated." Wow, does MSIE actually crash? Sounds like you are serving a broken .swf file and the plug-in is crashing. What version of MSIE are you running? What version of the Flash plug-in? If you don't include the Flash document embedded in the HTML document, does MSIE still crash? Try simply using HTML comments to remove it: > The page loads the first part > of the HTML content of the JSP (I can see the heading of the page) > and tries to display the Flash part (I can see the grey box of the > container) but then IE exits (btw: the page also loads perfectly well > when I just use plain HTML - but then I loose the JSP functionality, > of course). Interesting. So, if you generate an HTML page (say, using Firefox) using this JSP and then browse it using MSIE, everything is okay? It's only when you use the JSP dynamically with MSIE that it breaks? > This is my mod_jk log in debug mode: How about an access log instead of the mod_jk one? > It seems that Firefox "ignores" the missing mappings while IE does > not. What missing mappings? If you're talking about mod_jk, there's no interaction between the browser and mod_jk: the bytes are just being shuttled back and forth between httpd and Tomcat. > The JSP contains the following JSP part: > > > <%@ taglib uri="taglib.tld" prefix="j" %> > I agree with Hassan: it's odd to declare a taglib in the middle of a page.
