When you have an html page of size more than 1MB, Apache will restrict some part of the page to display. This would be usually images. So in order to allow Apache to show the entire page, the following code snippet has to be placed in web.xml file located in \jboss-4.0.5.GA\server\default\deploy\jbossweb-tomcat55.sar\conf path above <load-on-startup>1</load-on-startup> line.
<init-param>
<param-name>sendfileSize</param-name>
<param-value>-1</param-value>
</init-param>
