Method Detail

init

public void init(javax.servlet.ServletConfig config)
          throws javax.servlet.ServletException

Once loaded, Java Servlets continue to run until they are unloaded or the webserver is stopped. This example takes advantage of the extended Servlet life-cycle and runs a remote object in the Servlet VM. To initialize this remote object the Servlet Administrator should specify a set of parameters which will be used to download and install an initial remote server (see readme.txt). If configuration parameters are valid (not blank), the servlet will attempt to load and start a remote object and a registry in which the object may be bound.

Specified by:

init in interface javax.servlet.Servlet

Overrides:

init in class javax.servlet.GenericServlet

Parameters:

config - Standard configuration object for an http servlet.

Throws:

javax.servlet.ServletException - Calling super.init(config) may cause a servlet exception to be thrown.

doPost

public void doPost(javax.servlet.http.HttpServletRequest req,
          javax.servlet.http.HttpServletResponse res)
            throws javax.servlet.ServletException,
                   IOException

Execute the command given in the servlet request query string. The string before the first '=' in the queryString is interpreted as the command name, and the string after the first '=' is the parameters to the command.

Overrides:

doPost in class javax.servlet.http.HttpServlet

Parameters:

req - HTTP servlet request, contains incoming command and arguments

res - HTTP servlet response

Throws:

javax.servlet.ServletException - and IOException when invoking methods of req or res.

IOException

doGet

public void doGet(javax.servlet.http.HttpServletRequest req,
         javax.servlet.http.HttpServletResponse res)
           throws javax.servlet.ServletException,
                  IOException

Provide more intelligible errors for methods that are likely to be called. Let unsupported HTTP "do*" methods result in an error generated by the super class.

Overrides:

doGet in class javax.servlet.http.HttpServlet

Parameters:

req - http Servlet request, contains incoming command and arguments

res - http Servlet response

Throws:

javax.servlet.ServletException - and IOException when invoking methods of req or res.

IOException

doPut

public void doPut(javax.servlet.http.HttpServletRequest req,
         javax.servlet.http.HttpServletResponse res)
           throws javax.servlet.ServletException,
                  IOException

Overrides:

doPut in class javax.servlet.http.HttpServlet

Throws:

javax.servlet.ServletException

IOException

getServletInfo

public String getServletInfo()

Specified by:

getServletInfo in interface javax.servlet.Servlet

Overrides:

getServletInfo in class javax.servlet.GenericServlet
