This is a Java servlet filter (as per Servlet API 2.3). This filter lets you define the default parameters for HTTP requests. How to use it: a) download defparamflt.jar and save it in WEB-INF/lib b) describe this filter in web.xml. Initial parameters must describe your default HTTP parameters. For example:
<filter> <filter-name>DefaultParamFilter</filter-name> <filter-class>com.cj.defparam.DefParamFilter</filter-class> <init-param> <param-name>a</param-name> <param-value>5</param-value> </init-param> <init-param> <param-name>b</param-name> <param-value>test</param-value> </init-param> </filter> c) describe a mapping for this filter in web.xml
<filter-mapping> <filter-name>DefaultParamFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> and now your request will have the above mentioned default parameters a and b. Also you can describe values for your parameters in the following form: application.some_name and session.some_name in this case filter will lookup some_name attribute in the appropriate scope (application or session) and use its value as a parameter. For downloading: Default parameters filter: defparamflt.jar See also JSOS - the largest collection of servlets and filters.
