I have a problem in configuring the virtual host. I have configured a new Virtual host and have mapped an Enterprise Application with the created Virtual host. the problem that i have is that i can not open the Application on the Default host alias that is 80. I have to give the alternative port numbers to open the applicaion. What changes do I have to make in order to make the application open on the default port 80. Do I have to add the Data description in the Httpd.xml file ? There are no SSl in this Application. So please tell what i have to do in order to make it work on default port. Please give me a brief description for m issue.
