Interface javax.servlet.ServletConfig

public interface ServletConfig
This interface is implemented by services in order to pass configuration information to a servlet when it is first loaded. A service writer implementing this interface must write methods for the servlet to use to get its initialization parameters and the context in which it is running.

The ServletConfig interface can also be implemented by servlets. (GenericServlet does this.) When implemented by a servlet, the methods in the interface make getting the configuration data more convenient. For example, a servlet could implement getServletContext by writing, 

   public ServletContext getServletContext() {
    return getServletConfig().getServletContext();
   }
making access to the servlet's context object a single method invocation (a call to getServletContext()).

Method Index

o getInitParameter(String)
Returns a string containing the value of the named initialization parameter of the servlet, or null if the parameter does not exist.
o getInitParameterNames()
Returns the names of the servlet's initialization parameters as an enumeration of strings, or an empty enumeration if there are no initialization parameters.
o getServletContext()
Returns the context for the servlet.

Methods

o getServletContext 
 public abstract ServletContext getServletContext()
Returns the context for the servlet.

o getInitParameter 
 public abstract String getInitParameter(String name)
Returns a string containing the value of the named initialization parameter of the servlet, or null if the parameter does not exist. Init parameters have a single string value; it is the responsibility of the servlet writer to interpret the string.

o getInitParameterNames 
 public abstract Enumeration getInitParameterNames()
Returns the names of the servlet's initialization parameters as an enumeration of strings, or an empty enumeration if there are no initialization parameters.
