Introduction
When Struts development mode is set to true (also see Debugging Struts) the framework writes many informative messages to the log file. These messages include ones that indicate whether or not a specific parameter will be handled by the parameter interceptor and made available to the Action class. These log messages can be helpful in clearly identifying parameters that you do not want the parameter interceptor to process for security or other reasons. This article discusses how to exclude parameters from being handled by the parameter interceptor.
