Examples with IAS4RetryCallback com.helger.phase4.client.IAS4RetryCallback used on opensource projects

Example 1 with IAS4RetryCallback

use of com.helger.phase4.client.IAS4RetryCallback in project phase4 by phax.

the class AbstractAS4Client method sendMessageWithRetries.

/**
 * Send the AS4 client message created by
 * {@link #buildMessage(String, IAS4ClientBuildMessageCallback)} to the
 * provided URL. This methods does take retries into account. It synchronously
 * handles the retries and only returns after the last retry.
 *
 * @param <T>
 *        The response data type
 * @param sURL
 *        The URL to send the HTTP POST to
 * @param aResponseHandler
 *        The response handler that converts the HTTP response to a domain
 *        object. May not be <code>null</code>.
 * @param aCallback
 *        An optional callback for the different stages of building the
 *        document. May be <code>null</code>.
 * @param aOutgoingDumper
 *        An outgoing dumper to be used. Maybe <code>null</code>. If
 *        <code>null</code> the global outgoing dumper from
 *        {@link AS4DumpManager} is used.
 * @param aRetryCallback
 *        An optional callback to be invoked if a retry happens on HTTP level.
 *        May be <code>null</code>.
 * @return The sent message that contains
 * @throws IOException
 *         in case of error when building or sending the message
 * @throws WSSecurityException
 *         In case there is an issue with signing/encryption
 * @throws MessagingException
 *         in case something happens in MIME wrapping
 * @since 0.9.14
