Method Detail

headWithTitle

public static java.lang.String headWithTitle(java.lang.String title)

getIntParameter

public static int getIntParameter(javax.servlet.http.HttpServletRequest request,
                  java.lang.String paramName,
                  int defaultValue)

Read a parameter with the specified name, convert it to an int, and return it. Return the designated default value if the parameter doesn't exist or if it is an illegal integer format.

getCookieValue

public static java.lang.String getCookieValue(javax.servlet.http.Cookie[] cookies,
                              java.lang.String cookieName,
                              java.lang.String defaultValue)

Given an array of Cookies, a name, and a default value, this method tries to find the value of the cookie with the given name. If there is no cookie matching the name in the array, then the default value is returned instead.

getCookie

public static javax.servlet.http.Cookie getCookie(javax.servlet.http.Cookie[] cookies,
                                  java.lang.String cookieName)

Given an array of cookies and a name, this method tries to find and return the cookie from the array that has the given name. If there is no cookie matching the name in the array, null is returned.

filter

public static java.lang.String filter(java.lang.String input)

Given a string, this method replaces all occurrences of '<' with '<', all occurrences of '>' with '>', and (to handle cases that occur inside attribute values), all occurrences of double quotes with '"' and all occurrences of '&' with '&'. Without such filtering, an arbitrary string could not safely be inserted in a Web page.

         java.lang.String errMesg)
                  throws java.io.IOException
