A servlet is a Java program supporting a Web server or Web application server. Internally, Process Commander server code consists of several servlets, including these: VERIFY

Servlet	Description
CustomPassword	Supports the optional password management facility. PROJ-544
DiagnosticData	Supports downloading logs and report files from the System Management application, and downloading log files with the> System > Tools > Logs > Log FilesBYRNB 2/25/10 menu item. REALLY?
HeapDisplay	Diagnostics
PRHTTPService	Supports Service HTTP rules (Rule-Service-HTTP rule type) C-2650
PRImpExpServlet	Exports or imports rules, data, and other objects. Reserved for installation and support issues.
PRPortletService	Supports access from portlets.
PRServlet	Supports interactive users using HTTP and a web browser; presents dynamic content such as the portal displays and forms.
PRServletContainerAuth	Supports interactive users using HTTP and a web browser, when using J2EE context authentication, where users are authenticated by the application server.
PRServletLDAP1 to 5	Provides five working examples used by the Authentication wizard. See About the Authentication wizard.
PRServletProtected	Supports HTTP Basic Authentication over Secure Sockets Layer (SSL).
PRServletProtectedAuth	Supports HTTP Basic Authentication over SSL. SAME?
PRSOAPServlet	Responds to service requests from SOAP clients, uses packages of Service SOAP rules. By default, uses the same TCP/IP port as PRServlet.
PRSOAPServletContainerAuth	Responds to service requests from SOAP clients, uses packages of Service SOAP rules, when J2EE context authentication is in use. By default, uses the same TCP/IP port as PRServlet.
PRSOAPSimulator	Helps in testing a SOAP connector. See Testing Services and Connectors, a document on the Integration area of the Pega Developer Network.
PRStartup	Used briefly during system startup and to start agents and listeners.
PRTraceServlet	Implements the Tracer debugging tool.
RuleFileServlet	Serves static content through HTTP protocol messages, such as images, Cascading Style Sheets and JavaScript files. These are extracted to the file system from Rule-File-* rules upon first request.

(Technically, the above names are the URL patterns for the servlets, defined through the web.xml file for use with standard authentication. For example, the true servlet for the URL pattern PRServlet is WebStandard.) HITZM Ordinarily, a user accesses a servlet by entering its name in the Address line of a browser window. However, you can change settings in the in the web.xml file to mask or alter URLs associated with these servlets. SR-223 See Pega Developer Network article PRKB-10032 How to control access to servlets with Tomcat's web.xml file.

Additional servlets support LDAP access, testing, diagnostics, and internal operations. Both the internal name and the external URL names of each servlet are defined in the web.xml file.

In V5.X, a servlet named prdbutil supports installation, upgrade and archive operations. This servlet is not available in V6.X.

An external servlet can invoke Process Commander, itself a collection of servlets. For an example, see Pega Developer Network article PRKB-8783 How to invoke Process Commander from a servlet.
