Since:: Struts 1.2

populate

public static void populate(java.lang.Object bean,
                            javax.servlet.http.HttpServletRequest request)
                     throws javax.servlet.ServletException

Populate the properties of the specified JavaBean from the specified HTTP request, based on matching each parameter name against the corresponding JavaBeans "property setter" methods in the bean's class. Suitable conversion is done for argument types as described under convert().

populate

public static void populate(java.lang.Object bean,
                            java.lang.String prefix,
                            java.lang.String suffix,
                            javax.servlet.http.HttpServletRequest request)
                     throws javax.servlet.ServletException

Populate the properties of the specified JavaBean from the specified HTTP request, based on matching each parameter name (plus an optional prefix and/or suffix) against the corresponding JavaBeans "property setter" methods in the bean's class. Suitable conversion is done for argument types as described under setProperties.

If you specify a non-null prefix and a non-null suffix, the parameter name must match both conditions for its value(s) to be used in populating bean properties. If the request's content type is "multipart/form-data" and the method is "POST", the HttpServletRequest object will be wrapped in a MultipartRequestWrapper

getMultipartHandler

private static org.apache.struts.upload.MultipartRequestHandler getMultipartHandler(javax.servlet.http.HttpServletRequest request)
                                                                             throws javax.servlet.ServletException

Try to locate a multipart request handler for this request. First, look for a mapping-specific handler stored for us under an attribute. If one is not present, use the global multipart handler, if there is one.

getAllParametersForMultipartRequest

private static java.util.Map getAllParametersForMultipartRequest(javax.servlet.http.HttpServletRequest request,
                                                                 org.apache.struts.upload.MultipartRequestHandler multipartHandler)

Create a Map containing all of the parameters supplied for a multipart request, keyed by parameter name. In addition to text and file elements from the multipart body, query string parameters are included as well.

printableURL

public static java.lang.String printableURL(java.net.URL url)

Compute the printable representation of a URL, leaving off the scheme/host/port part if no host is specified. This will typically be the case for URLs that were originally created from relative or context-relative URIs.

actionURL

public static java.lang.String actionURL(javax.servlet.http.HttpServletRequest request,
                                         org.apache.struts.config.ActionConfig action,

Since:: Struts 1.1

forwardURL

public static java.lang.String forwardURL(javax.servlet.http.HttpServletRequest request,
                                          org.apache.struts.config.ForwardConfig forward)

Return the context-relative URL that corresponds to the specified ForwardConfig. The URL is calculated based on the properties of the org.apache.struts.config.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 org.apache.struts.config.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.)

Since:: Struts 1.1

forwardURL

public static java.lang.String forwardURL(javax.servlet.http.HttpServletRequest request,
                                          org.apache.struts.config.ForwardConfig forward,
                                          org.apache.struts.config.ModuleConfig moduleConfig)

Return the context-relative URL that corresponds to the specified ForwardConfig. The URL is calculated based on the properties of the org.apache.struts.config.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.

- $M - Replaced by the module prefix for the application module processing this request.
- $P - Replaced by the path property of the specified org.apache.struts.config.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.)
