  +--ipworks.Webform

public class Webform

extends java.lang.Object

The WebForm bean is used to POST data to interactive web pages or scripts (CGI, ASP, etc..), similar to what HTML forms do.

The inputs to the script are provided through the FormVars collection. Once the inputs are defined, set the URL property to the address of the script and call the Submit method. Alternatively, you may call the SubmitTo method with URL as the parameter.

The output of the page or script is provided via the Transfer event.

The Encoding property allows you to specify the proper encoding for the form input (this is normally 'urlencoding').

Method Detail

getAccept

public java.lang.String getAccept()

A list of acceptable MIME types for the request.

If the Accept property contains a non-empty string, an HTTP Accept header is added to the request.

The Accept header is used for content negotiation. It consists of a comma-separated list of acceptable MIME types.

setAccept

public void setAccept(java.lang.String accept)
               throws IPWorksException

A list of acceptable MIME types for the request.

If the Accept property contains a non-empty string, an HTTP Accept header is added to the request.

The Accept header is used for content negotiation. It consists of a comma-separated list of acceptable MIME types.

IPWorksException

getAuthScheme

public int getAuthScheme()

The authorization scheme to be used when server authorization is to be performed.

Use the AuthScheme property to tell the bean which type of authorization to perform when the User and Password properties are set.

AuthScheme should be set to authNone (3) when no authentication is expected.

By default, AuthScheme is authBasic (0), and if the User and Password properties are set, the bean will attempt basic authentication. If AuthScheme is set to authDigest (1), digest authentication will be attempted instead.

If AuthScheme is set to authProprietary (2) then the authorization token must be supplied through Authorization property. Note that, if you set the Authorization property, the AuthScheme will be set automatically to authProprietary (2) by the control.

If AuthScheme is set to authNtlm (4) NTLM authentication will be used. This option is only available in the SSL package.

For security reasons, setting this property will clear the values of User and Password .

setAuthScheme

public void setAuthScheme(int authScheme)
                   throws IPWorksException

IPWorksException

getContentType

public java.lang.String getContentType()

Content type for posted data.

If the ContentType property contains a non-empty string, a Content-Type HTTP request header is added to the request. The purpose of the header is to show the contents of the data being POST-ed to the server.

The most common example is posting of HTML form input data. In that case, the ContentType property must be set to "application/x-www-form-urlencoded" .

setContentType

public void setContentType(java.lang.String contentType)
                    throws IPWorksException

Content type for posted data.

IPWorksException

getCookies

public HTTPCookieList getCookies()

Collection of cookies.

All HTTPCOOKIE specified in the collection are added to the outgoing HTTP request.

The SetCookie event displays the cookies and their properties as set by the server, and those cookies are also maintained in the Cookies property.

MaxHTTPCookiescan be used to control the number of cookies saved.

This collection is indexed from 0 to Count - 1.

setCookies

public void setCookies(HTTPCookieList cookies)
                throws IPWorksException

Collection of cookies.

All HTTPCOOKIE specified in the collection are added to the outgoing HTTP request.

This collection is indexed from 0 to Count - 1.

IPWorksException

getEncoding

public int getEncoding()

The encoding type for the form data.

This property determines how the bean encodes the form contents. It is equivalent to the 'ENCTYPE' attribute of an HTML form.

It can take one of the following values:

encURLEncoding (0)

This is the most common encoding for HTML form contents.

encMultipartFormData (1)

This is MIME encoding allowing transmission of binary data.

encQueryString (2)

This is an older form of encoding where the actual parameters are appended to the URL query string. (Generally not recommended because most servers limit the size of the URL to less than 1K or 2K).

setEncoding

public void setEncoding(int encoding)
                 throws IPWorksException

The encoding type for the form data.

This property determines how the bean encodes the form contents. It is equivalent to the 'ENCTYPE' attribute of an HTML form.

encURLEncoding (0)

This is the most common encoding for HTML form contents.

encMultipartFormData (1)

This is MIME encoding allowing transmission of binary data.

encQueryString (2)

This is an older form of encoding where the actual parameters are appended to the URL query string. (Generally not recommended because most servers limit the size of the URL to less than 1K or 2K).

IPWorksException

getFirewall

public ipworks.Firewall getFirewall()

A set of properties related to firewall access.

This is a FIREWALL type property which contains fields describing the firewall through which the bean will attempt to connect.

setFirewall

public void setFirewall(ipworks.Firewall firewall)
                 throws IPWorksException

A set of properties related to firewall access.

This is a FIREWALL type property which contains fields describing the firewall through which the bean will attempt to connect.

IPWorksException

getFollowRedirects

public int getFollowRedirects()

Determines what happens when the server issues a redirect.

Normally, the bean returns an error if the server responds with an "Object Moved" message. If FollowRedirects is set to frAlways (1) the new URL for the object is retrieved automatically every time.

If FollowRedirects is set to frSameScheme (2), the new URL is retrieved automatically only if the URLScheme is the same, otherwise the bean throws an IPWorksException raises an IPWorksException exception .

Note that following the HTTP specification, unless FollowRedirects is set to frAlways (1), automatic redirects will be performed only for 'GET' or 'HEAD' requests. Other methods could potentially change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server and port are different than the existing one, User and Password are also reset to empty, unless FollowRedirects is set to frAlways (1), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g. new authentication parameters).

The default value is frNever (0). In this case, redirects are never followed, and a runtime error is generated instead.

setFollowRedirects

public void setFollowRedirects(int followRedirects)
                        throws IPWorksException

Determines what happens when the server issues a redirect.

Normally, the bean returns an error if the server responds with an "Object Moved" message. If FollowRedirects is set to frAlways (1) the new URL for the object is retrieved automatically every time.

If FollowRedirects is set to frSameScheme (2), the new URL is retrieved automatically only if the URLScheme is the same, otherwise the bean throws an IPWorksException raises an IPWorksException exception .

Note that following the HTTP specification, unless FollowRedirects is set to frAlways (1), automatic redirects will be performed only for 'GET' or 'HEAD' requests. Other methods could potentially change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server and port are different than the existing one, User and Password are also reset to empty, unless FollowRedirects is set to frAlways (1), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g. new authentication parameters).

The default value is frNever (0). In this case, redirects are never followed, and a runtime error is generated instead.

IPWorksException

getFormVars

public FormVarList getFormVars()

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the bean initiate connections (or accept in the case of server beans) only through that interface.

If the bean is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

setLocalHost

public void setLocalHost(java.lang.String localHost)
                  throws IPWorksException

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

IPWorksException

getParsedHeaders

public HeaderList getParsedHeaders()

Collection of headers returned from the last retrieval.

Whenever headers are returned from the server, the headers are parsed into a collection of headers. Each HEADER in this collection contains information describing that header.

MaxHeaderscan be used to control the number of headers saved.

This collection is indexed from 0 to Count - 1.

getPassword

public java.lang.String getPassword()

A password if authentication is to be used.

If AuthScheme is set to HTTP Basic Authentication, The User and Password are Base64 encoded and the result is put in theAuthorizationconfig setting in the form "Basic [encoded-user-password]".

If AuthScheme is set to HTTP Digest Authentication, the User and Password properties are used to respond to the HTTP Digest Authentication challenge from the server.

The User and Password properties must be set only after the URL property is set. When the URL property is set, for security reasons, the User and Password properties are immediately cleared.

setPassword

public void setPassword(java.lang.String password)
                 throws IPWorksException

A password if authentication is to be used.

If AuthScheme is set to HTTP Basic Authentication, The User and Password are Base64 encoded and the result is put in theAuthorizationconfig setting in the form "Basic [encoded-user-password]".

IPWorksException

getStatusLine

public java.lang.String getStatusLine()

The first line of the last server response.

This value can be used for diagnostic purposes. If an HTTP error is returned when calling a method of the bean, the error string is the same as the StatusLine property.

The HTTP protocol specifies the structure of the StatusLine as: [HTTP version] [Result Code] [Description].

getTimeout

public int getTimeout()

A timeout for the bean.

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion, or an error condition is encountered.

If Timeout is set to a positive value, the bean will wait for the operation to complete before returning control.

The bean will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the bean throws an IPWorksException raises an IPWorksException exception .

Please note that by default, all timeouts are inactivity timeouts , i.e. the timeout period is extended by Timeout seconds when data is successfully sent or received.

Optionally, the behaviour of the bean may be changed to absolute timeouts , i.e. the bean will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.

This behavior is controlled by theAbsoluteTimeoutconfiguration setting.

The default value for the Timeout property is 60 (seconds).

setTimeout

public void setTimeout(int timeout)
                throws IPWorksException
