Chapter 22 Creating Web Applications
Importing and exporting Web applications
You can export Web applications from Jaguar Manager to deploy
them on another server. Jaguar supports two archive formats for
Web applications:
- J2EE Web archive
(WAR) The WAR format is the standard for servers that support J2EE.
This format allows portability to other vendor's J2EE servers,
but container-specific information is not included in the archive. In
particular, these items must be configured manually after importing
a WAR file:
- Jaguar JAR For exporting between Jaguar 3.6 or later servers. This format,
while proprietary, preserves all information in the Web application.
When importing, EJB references, resource references, and role mappings
are preserved. You must ensure that the referenced items are in
place before running the imported Web application.
Consider the synchronize feature instead of using archives
If you are deploying between Jaguar servers, you may find
the synchronize feature easier than exporting and importing archives.
Synchronization replicates a Web application directly between servers.
See Chapter 3, "Jaguar Clusters and Synchronization" in
the Jaguar CTS System Administration Guide for
more information.
To export a Web application:
-
Expand the Web Applications folder, then highlight
the icon that represents your application.
-
If exporting in WAR format, choose File | Export | J2EE
WAR. If exporting in Jaguar JAR format, choose File | Export | Jaguar
JAR.
-
Enter a path and file name for the file to be created,
including the .war or .ear extension.
-
Click Next. The Export wizard creates an archive of
your Web application, displaying status information in the window.
-
When the export is complete, click Close.
To import a Web application:
-
Highlight the top-level Web Applications folder.
If importing a WAR file, choose File | Deploy | J2EE
WAR. If importing a Jaguar JAR, choose File | Deploy | Jaguar
JAR.
-
Enter the path to the WAR or JAR file and click Next.
-
The Deploy wizard reads the file and creates the Web
application. Any errors are displayed in the status window. Review
the status information, then click Close.
Use the status dialog as a to-do list
In the deployment status dialog box, Jaguar Manager display
warnings for each setting that requires further attention before
you can run the Web application. You can copy and paste this text
to a text editor to use as a to-do list.
What is created during import
When importing a Jaguar JAR, the Deploy wizard creates a Web
application that is identical to the original.
When importing a WAR, the Deploy wizard creates a Web application
with the same name as the display name in the WAR file's
XML descriptor. If there is no display name, the new Web application
has the same name as the WAR file. For each servlet defined in the
WAR, the Deploy wizard creates a Web component with the same name
as the as the servlet-name element in the Web application
deployment descriptor.
Before running servlets or JSPs in the Web application, you
may need to configure the following settings in the Web Application
Properties dialog box:
- Role mappings
- Resource references
- EJB references
- Environment properties
