webapp not on 8080 and html:base

[Vilpesh Mistry]

hi,
iam using struts and making a website.

During the development phase, we had used the default port 8080.
so to access my webpage i used to write,
http://localhost:8080/simliv/action/welcome

well all files in my jsp pages use struts <html:base> tag

so under view source for any jsp page,
the url looks like http://localhost:8080/simliv/welcome.jsp

well now its deployment time,after deploying,i have been asked to remove
the port number ie 8080 coming after localhost.

I think this whole is configuring apache and tomcat,
please specify how do i configure tomcat so that when i access

http://localhost/simliv/action/welcome ,

i get the same welcome page and all other pages without the port number after the localhost

The problem been that struts carries the base address 8080 in all other pages if html:base tag is used.

thanks
