8.8: Using internal tools

You can use WebSphere Application Server servlets and internal tools to help diagnose problems.

Servlets

View file samples.html for information on sample serlvets shipped with the product. Most WebSphere Application Server servlets are located in the examples directory:

servlet location



The following table describes servlets that can be used as debug tools:

servlet            location description
Hit Count <WebSphere\AppServer>\hosts\default_host\examples\ Verifies correct implementation of Servlets, JSPs, EJBs, and HTTP Session.
Snoop Servlet <WebSphere\AppServer>\hosts\default_host\default_app\servlets\Snoop.class Useful for examining request parameters coming from the client and for verifying the operation of the servlet engine.
ShowCfg <WebSphere\AppServer>\hosts\default_host\examples\ Useful for validating the configuration of the system.
BeenThere <WebSphere\AppServer>\hosts\default_host\examples\web\beenthere.html Useful for demonstrating and testing session persistance.

Internal tools

The available internal tools apply to specific operations. For example, the jdbctest.javaTM tool tests JDKTM settings and database access.

See theWebSphere Problem Determination Tools website for detailed information about these tools. The website also offers you the opportunity to add ideas about tools and add a new tool. Check the website periodically for updates.
