Java™ Platform, Enterprise Edition (Java EE)
applications can use Uniform Resource Locators (URLs) by looking up references
to logically named URL connection factories through the java:comp/env/url subcontext,
which is declared in the application deployment descriptor and mapped to installation
specific URL resources.
About this task
As in the case of other Java EE resources, this can be done in order
to eliminate the need for the application to hard code references to external
resources. The process is the same used with other Java EE resources, such as JDBC objects
and JavaMail sessions.
Procedure
- Develop an application that
relies on naming features.
- Define resource references
while assembling your application. A URL resource that uses
a built-in protocol, such as HTTP, FTP, or file, can use the default URL provider.
URL resources that use other protocols need to use a custom URL provider.
- Configure your URL resources within an application.
- Open the administrative console.
- Click Resources>URL in the console navigation
tree.
- Click either URL Providers or URLs to modify the
appropriate resource.
- Optional: Configure URL providers and URLs within an
application client using the Application
Client Resource Configuration Tool (ACRCT).
- Manage URL providers and URL resources used by the deployed application.
To update or remove existing URL configurations:
- Open the administrative console.
- Click Resources > URL in the console navigation
tree.
- Click either URL Providers or URLs to modify the
appropriate resource.
- Select the URL to modify.
- Modify the URL properties.
- Click Apply or OK.
To remove URL providers and URLs, after step 2, click URL_provider > URLs.
Select the URL you want to remove and click Delete. Then, click Apply or OK.
