Back Forward Servlet

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

Servlet

Description

DiagnosticData Supports downloading logs and report files from the System Management application, and downloading log files with the> System > Tools > Logs > Log Files menu item.
HeapDisplay Diagnostics
PRHTTPService Supports Service HTTP rules (Rule-Service-HTTP rule type)
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 Java EE 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.
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 Java EE context authentication is in use. By default, uses the same TCP/IP port as PRServlet.
PRSOAPSimulator Helps in testing a SOAP connector. See PDNTesting Services and Connectors, a document on the Integration area of the PDN.
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.) 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.

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.

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

Advanced featureAn external servlet can invoke PRPC, itself a collection of servlets. For an example, see PDN article PDN 8783 How to invoke Process Commander from a servlet.
