Examples with TransactionStatusException org.jboss.jbossts.star.provider.TransactionStatusException used on opensource projects

Example 1 with TransactionStatusException

use of org.jboss.jbossts.star.provider.TransactionStatusException in project narayana by jbosstm.

the class Coordinator method beginTransaction.

/**
 * Performing a POST on Transaction Manager URL @see TxSupport.TX_SEGMENT with no content
 * as shown below will start a new transaction with a default timeout.
 * A successful invocation will return 201 and the Location header MUST contain the URI
 * of the newly created transaction resource, which we will refer to as the transaction-coordinator
 * in the rest of this specification. Two related URLs MUST also be returned,
 * one for use by the terminator of the transaction (typically referred to as the client)
 * and one used for registering durable participation in the transaction (typically referred
 * to as the server). These linked URLs can be of arbitrary format.
 * The rel names for the links are:
 * @see org.jboss.jbossts.star.util.TxLinkNames#TERMINATOR and @see TxLinkNames#PARTICIPANT
 *
 * @param info uri context
 * @param headers http headers
 * @param content empty if no transaction timeout is required otherwise the number of milliseconds
 * after which the transaction is eligible for being timed out. The content should have the format
 * TxSupport#TIMEOUT_PROPERTY milliseconds
 * @return http status code
