I do have a WordPress.com hosted blog. And, I am aware that WordPress do not support Java - I mentioned it in my first post under the options, did I not?
As to the codes:
<!--#include virtual="http://widgets.bookmooch.com/widget/en/html/inv_recent_cover/simonehogan/10/+/" -->
<br><font face="arial" size=1"><a href="http://www.bookmooch.com">Exchange your books at BookMooch.com</a></font>
<iframe FRAMEBORDER=0 src="http://widgets.bookmooch.com/widget/en/html/inv_recent_cover/simonehogan/10/+/" width="300" height="200"></iframe>
<br><font face="arial" size=1"><a href="http://www.bookmooch.com">Get books online from BookMooch.com</a></font>
<?php include("http://widgets.bookmooch.com/widget/en/html/inv_recent_cover/simonehogan/10/+/"); ?>
<br><font face="arial" size=1"><a href="http://www.bookmooch.com">Exchange your books at BookMooch.com</a></font>
<%= [ns_httpget "http://widgets.bookmooch.com/widget/en/html/inv_recent_cover/simonehogan/10/+/"] %>
<br><font face="arial" size=1"><a href="http://www.bookmooch.com">Trade your books at BookMooch.com</a></font>
<% url = "http://widgets.bookmooch.com/widget/en/html/inv_recent_cover/simonehogan/10/+/"; set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP"); xmlhttp.open "GET", url, false; xmlhttp.send ""; Response.write xmlhttp.responseText; set xmlhttp = nothing; %>
<br><font face="arial" size=1"><a href="http://www.bookmooch.com">Give away your books at BookMooch.com</a></font>
These are the only ones where javascript is not mentioned.
