Yes. Laszlo only requires a back-end web server that can supply XML over HTTP. This only requires the HTTP's content type be set to "text/xml". This makes it easy to update existing Java servlet applications to support Laszlo, as you only the JSP file needs to be changed to product XML output.
I have some doubts about installing and configuring Laszlo and Struts Application. The Tomcat 6.0 is already installed on my computer.
Can i use the already installed tomcat by configuration using web.xml without using LPS.
I am confused, and did not got any clue, so can you please help me ?
