A servlet is a Java program that extends capabilities of the server, responds to any incoming requests, and construct responses. Servlets are used during authentication in commonly used protocols, such as Lightweight Directory Access Protocol (LDAP), Security Assertion markup Language (SAML), and OpenID connect, and other.
Pega Cloud supports system-created servlets (default) and custom (user-defined) servlets, which are created by the security administrator.
The Availability column displays whether the servlet has been enabled or disabled, and whether a restart is required for changes to take effect.
When you add a servlet on the Servlet Management landing page, the URL pattern that you
configure for the servlet adds servlet mappings for the corresponding servlet. For
example, if there is a URL pattern named
PRServlet under a servlet
WebStandard, then two servlet mappings are created:
When you make servlet management changes, you need to restart your system for the changes to take effect. To request a restart of the entire environment, select New request in My Support Portal. For more information, see:
The image below shows the Servlet Management landing page.
To the right of the servlets, there are vertical ellipsis, when clicked, the following options are displayed: Clone, Configure, and Copy URL.
An image of the options available on a system-generated servlet is shown below:
An image of the options available on a user-created servlet is shown below:
Clicking Clone launches a dialog box similar to adding a new servlet. However, the Purpose and Servlet authentication type fields have the same information as the servlet you are cloning. Any Initialization parameters will also be carried over when a servlet is cloned.
When you want to rename an existing servlet or create a new servlet, with similar properties as another servlet, you can clone that servlet.
When you rename an existing servlet, you can clone the new servlet with the updated name, and then disable the original servlet so that only the new servlet is accessible.The following figure shows a example of a cloned servlet configuration:
The Configure option provides a summary of the servlet information and shows controls for editing and making changes to the configured servlet.
The following figure shows an example of the servlet configuration dialog box:
Servlet copy URL copying
You can use the Copy URL option to copy the servlet URL and use that URL for testing or other purposes.
- Servlet name
- The standard URL to the specific servlet on the server side, and the Copy URL option provides access to the corresponding servlet URL in a browser without manually typing the IP address.
- The default servlet URL pattern. If you access a URL after /prweb and the servlet is not found, you are redirected to the default servlet where * is configured as the URL pattern.
- If you do not provide the * URL, then system becomes inaccessible. This setting is the minimum servlet configuration that is required for an application. Without this configuration, a 403 error is displayed.
You can copy the URL pattern of the Servlet name, as shown in the following example:
