The New Web Project with Existing Sources wizard creates a new
from an existing web application source folder. You open the
New Web Project with Existing Sources wizard by opening the New
Project wizard and selecting the Web Project with Existing Sources template
from the Java Web category.
Your existing web application source does not have to adhere to any particular directory
structure. You specify the locations of the configuration files, libraries,
and source roots. The only requirement is that the module contain a valid web.xml
deployment descriptor.
In the Existing Sources and Libraries page, you specify the following properties:
Web Pages Folder. Specifies the location of your web pages.
You must have at least a valid web.xml
deployment descriptor in the web pages folder to complete the wizard.
The IDE does not convert deployment descriptors for unsupported application
servers to the Glassfish application server deployment descriptors. There are external
tools you can use for this purpose.
WEB-INF Content. Specifies the location of the application's WEB-INF content.
Libraries Folder. Specifies the location of the class libraries that the
web application depends on. All JAR files in this folder are added to the web application
project's classpath and packaged with the application for deployment.
The IDE only scans this folder once when you create the project. After
the project is created, adding JAR files to this folder outside the IDE
does not add them to the module's classpath. You have to add them manually
through the Libraries tab of the module's Project Properties dialog box.
Source Package Folders.
Test Package Folders. Specifies each of the project's source package folders (containing
source packages) and test package folders (containing JUnit tests). You can
have multiple source roots in a standard project, with the following exceptions:
The source root cannot already exist in another IDE project.
The source root cannot already be added to another compilation unit of the
same project. For example, a source root that is registered under Test Packages
cannot be added to the list of Source Packages.
All of the source roots are packaged into the same WAR file and share the
same classpath.
If you have a source root that needs to be used by several projects, you
should create a separate project for the source root and set
up compilation dependencies between the projects.
When you click Finish, the folder specified as the Location property
is used to determine where the web pages, Java sources and libraries are found. The
project is created on your computer and opened in
the IDE. You can view its logical structure in the Projects window and its file
structure in the Files window.
