HTML URL

Question

Hi,
I have a Html page ( has 2 jsps as frames) which is refered as follows: http://hostname/appname/index.html
now when ever there is change in host name, it is a big overhead to redirect and some times not possible to redirect.
I would like to know if there is any way we refer the same link as
http://SomeHostIndependentName/index.html in the intranet.
running on tomcat 3.x web server

Answer 1

The following is the piece of info that i used to connect to db and pass the base url to all the jsp pages in my applicaiton.
Below are the contents of the web.xml that is being used in the Jbuilder/Tomcat4.0.1 environment.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<context-param>
<param-name>baseurl</param-name>
<param-value>http://sat:8080</param-value>
</context-param>
<context-param>
<param-name>dbpassword</param-name>
<param-value>sat123</param-value>
</context-param>
<context-param>
<param-name>dburl</param-name>
<param-value>jdbc:oracle:thin:@192.168.0.213:1521:satora</param-value>
</context-param>
<context-param>
<param-name>dbuser</param-name>
<param-value>sat</param-value>
</context-param>
</web-app>
You have to use the following command in the JSP to get the required parameters read from the web.xml file.
String strBaseUrl = getServletContext().getInitParameter("baseurl");
Hope this will meet your need.
Good luck
