If you already have your existing Web site packaged as a Web
archive (WAR) file, import the WAR. Your existing resources will appear in
the Project Explorer in a Web project.
If you need to import Web resources outside of a WAR, such as
a multiple HTML files, JSP files, images, and other files used in your current
Web site, you need to first create an empty dynamic Web project, and then import your existing resources.
Check that your Web project contains a Web Site Navigation file
in the Project Navigator view. This file indicates that the project is enabled
for Web Site Designer support.
If there is no file present, most likely the project you imported
is not a valid project; therefore, the Web Site Designer configuration file does not exist
in the project. To create this file and use the features of Web Site Designer, enable Web Site Designer support for your Web project.
If the file is present, it is because you created an empty dynamic
Web project before importing your Web resources.
Double-click the Web Site Navigation file to open Web Site Designer
to the Navigation view.
Add the existing pages to Web Site Designer's Navigation
view. You should understand the importance of Web
site development in order to ensure you add your existing pages correctly.
Check your Web site structure. Though your existing pages can be
added to the Navigation view with the links and relationships intact, you
must still check the Web Site Navigation to make sure those relationships
are represented correctly now that they have been imported.
Test your new Web project on a server. Testing the project
ensures that all of your resources have been imported properly. For more information,
see the server tools documentation.
