Method Detail

registerContentHandler

public static void registerContentHandler(java.lang.String content_type,
                                          ContentHandlerFactory factory)

Registers a new content-type with the server. ContentHandler objects are invoked to process input of their particular MIME type. A ContentHandlerFactory can be used to register several different MIME types.

Parameters:

content_type - A String specifying the new MIME content type to be supported (for example, "text/xml").

factory - A ContentHandlerFactory that will process requests for the new MIME type.

See Also:

ContentHandler, ContentHandlerFactory

removeContentHandler

public static void removeContentHandler(java.lang.String content_type)

Deregisters a content type from the server. The default content handler will be associated with this content type.

Parameters:

content_type - A String specifying the MIME content type to deregistered.

getContentHandler

public static ContentHandler getContentHandler(java.lang.String content_type)

Returns a new ContentHandler for the specified content type.

Parameters:

content_type - A String specifying a MIME content-type.

Returns:

A ContentHandler for the specified content type.

registerCoderForMultipart

public static void registerCoderForMultipart(java.lang.String serviceName,
                                             java.lang.Class coder)

Registers a service and associated coder for a multipart content handler (ContentHandler_Multipart). The specified coder is the content handler for REST requests for that service.

Parameters:

serviceName - The name of the service for which the coder will handle REST requests. In a REST request URL, the service name appears after “rest” or “restv2” directive. For example, in the following URL, RestCoderService is the service name: http://localhost:5555/restv2/RestCoderService

coder - The derived Type of super class Coder.

removeCoderForMultipart

public static void removeCoderForMultipart(java.lang.String serviceName)

Unregisters the coder for the specified service from multipart content handler.

Parameters:

serviceName - The name of the service name for which you are unregistering the coder for the multipart content handler. In a REST request URL, the service name appears after the “rest” or “restv2” directive.

logError

public static void logError(java.lang.Throwable t)

Logs the specified error to the server's default log file. The name of the default log is usually "error.log" in the server's logs directory.
Note: Service.throwError method logs subclasses of java.lang.RuntimeException by default. Be careful not to double-log your errors.

Parameters:

t - A Throwable object specifying the error to be logged.

See Also:

logError(Values), Service.throwError(java.lang.Throwable)

logError

public static void logError(Values v)

Logs the specified error to the server's default log file. The name of the default log is usually "error.log" in the server's logs directory.
Note: Service.throwError method logs subclasses of java.lang.RuntimeException by default. Be careful not to double-log your errors.

Parameters:

v - A Values object specifying the error to be logged.

See Also:

logError(Throwable), Service.throwError(java.lang.Throwable)

logSecurity

public static void logSecurity(java.lang.String message,
                               boolean success)

Logs a message to the server's security log. The security log may be on the file system, in the logs directory, or it may be in the ISCoreAudit database, as configured on the Settings > Logging page of Integration Server Administrator. This method writes to the security log only if the Security Logger is enabled and Custom is selected in the Security Areas to Audit on the Settings > Logging > Edit Security Logger Details page.

Parameters:

message - The message to write to the security log.

success - Indicates whether the action being logged succeeded or failed. For example, if the client attempts to access a protected resource, true indicates the access succeeded and false indicates the access failed.

getLogStream

public static LogOutputStream getLogStream(java.lang.String logfile)

Opens a log file in the server's default logs directory. This should only be used to obtain handles to new log files for app-specific logging purposes. By convention, the name should be something like “myapp.log".

Parameters:

logfile - A String specifying the name of the new log file.

Returns:

The LogOutputStream which is used to write to the new log file.

sendMail

public static void sendMail(java.lang.String to,
                            java.lang.String from,

                            java.lang.String body)

Sends an e-mail message to the specified recipient. This method is usually called on behalf of a service that's failing. The SMTP server must be set in the configuration file, watt.server.smtpServer, for this method to work properly.
