Table of Contents
Unsets a servlet context-initialization parameter of a deployed web application or module.
Synopsis
asadmin [asadmin-options] unset-web-context-param [--help]
--name=context-param-name application-name[/module]
Description
The unset-web-context-param subcommand unsets a servlet context-initialization parameter of one of the following items:
-
A deployed web application
-
A web module in a deployed Jakarta EE application
When a parameter is unset, its value reverts to the value, if any, that is set in the application’s deployment descriptor.
The application must already be deployed. Otherwise, an error occurs.
The parameter must have previously been set by using the set-web-context-param subcommand. Otherwise, an error occurs.
|
Note
|
Do not use the unset-web-context-param subcommand to change the value of a servlet context-initialization parameter that is set in an
application’s deployment descriptor. Instead, use the set-web-context-param subcommand for this purpose.
|
This subcommand enables you to change the configuration of a deployed application without the need to modify the application’s deployment descriptors and repackage and redeploy the application.
This subcommand is supported in remote mode only.

module:
The relative path to the module within the application’s enterprise archive (EAR) file. The path to the module is specified in the
module element of the application’s application.xml file.
module is required only if the servlet context-initialization parameter applies to a web module of a Jakarta EE application. If
specified, module must follow application-name, separated by a slash (/).

+
<module>
<web>
<web-uri>myWebModule.war</web-uri>
</web>
