getScope

public static int getScope(String scope)

getStyle

public static int getStyle(String style,
                           String errCode)
                    throws javax.servlet.jsp.JspException

Throws:

javax.servlet.jsp.JspException

escapeXml

public static String escapeXml(String buffer)

Performs the following substring replacements (to facilitate output to XML/HTML pages): & -> & < -> < > -> > " -> " ' -> ' See also OutSupport.writeEscapedXml().

getContentTypeAttribute

public static String getContentTypeAttribute(String input,
                                             String name)

Get the value associated with a content-type attribute. Syntax defined in RFC 2045, section 5.1.

URLEncode

public static String URLEncode(String s,
                               String enc)

URL encodes a string, based on the supplied character encoding. This performs the same function as java.next.URLEncode.encode in J2SDK1.4, and should be removed if the only platform supported is 1.4 or higher.

Parameters:

s - The String to be URL encoded.

enc - The character encoding

Returns:

The URL encoded String [taken from jakarta-tomcat-jasper/jasper2 org.apache.jasper.runtime.JspRuntimeLibrary.java]

getRequestLocales

public static Enumeration getRequestLocales(javax.servlet.http.HttpServletRequest request)

HttpServletRequest.getLocales() returns the server's default locale if the request did not specify a preferred language. We do not want this behavior, because it prevents us from using the fallback locale. We therefore need to return an empty Enumeration if no preferred locale has been specified. This way, the logic for the fallback locale will be able to kick in.
