Deprecated. Use TagUtils.encodeURL(String) instead. This will be removed after Struts 1.2.

Use the new URLEncoder.encode method from Java 1.4 if available, else use the old deprecated version. This method uses reflection to find the appropriate method; if the reflection operations throw exceptions, this will return the url encoded with the old URLEncoder.encode method.

forwardURL

public static String forwardURL(HttpServletRequest request,
                                ForwardConfig forward)
Return the context-relative URL that corresponds to the specified ForwardConfig. The URL is calculated based on the properties of the ForwardConfig instance as follows:
  • If the contextRelative property is set, it is assumed that the path property contains a path that is already context-relative:
  • If the path property value starts with a slash, it is returned unmodified.
  • If the path property value does not start with a slash, a slash is prepended.
  • Acquire the forwardPattern property from the ControllerConfig for the application module used to process this request. If no pattern was configured, default to a pattern of $M$P, which is compatible with the hard-coded mapping behavior in Struts 1.0.
  • Process the acquired forwardPattern, performing the following substitutions:
    • $M - Replaced by the module prefix for the application module processing this request.
    • $P - Replaced by the path property of the specified ForwardConfig, prepended with a slash if it does not start with one.
    • $$ - Replaced by a single dollar sign character.
    • $x (where "x" is any charater not listed above) - Silently omit these two characters from the result value. (This has the side effect of causing all other $+letter combinations to be reserved.)
  • Parameters:
    request - The servlet request we are processing
    forward - ForwardConfig to be evaluated

    Returns:
    context-relative URL

    Since:
    Struts 1.1

                                    ForwardConfig forward,
                                    ModuleConfig moduleConfig)
    Return the context-relative URL that corresponds to the specified ForwardConfig. The URL is calculated based on the properties of the ForwardConfig instance as follows:
    • If the contextRelative property is set, it is assumed that the path property contains a path that is already context-relative:
    • If the path property value starts with a slash, it is returned unmodified.
    • If the path property value does not start with a slash, a slash is prepended.
  • Acquire the forwardPattern property from the ControllerConfig for the application module used to process this request. If no pattern was configured, default to a pattern of $M$P, which is compatible with the hard-coded mapping behavior in Struts 1.0.
  • Process the acquired forwardPattern, performing the following substitutions:
    • $M - Replaced by the module prefix for the application module processing this request.
    • $P - Replaced by the path property of the specified ForwardConfig, prepended with a slash if it does not start with one.
    • $$ - Replaced by a single dollar sign character.
    • $x (where "x" is any charater not listed above) - Silently omit these two characters from the result value. (This has the side effect of causing all other $+letter combinations to be reserved.)
  • Parameters:
    request - The servlet request we are processing
    forward - ForwardConfig to be evaluated
    moduleConfig - Base forward on this module config.

    Returns:
    context-relative URL

    Since:
