/**
 * 17.6.2.5 Mandatory
 * 
 * The Container must invoke an enterprise Bean method whose transaction
 * attribute is set to Mandatory in a client's transaction context. The client
 * is required to call with a transaction context.
 * 

 * * If the client calls with a transaction context, the container invokes the
 * enterprise Bean's method in the client's transaction context.
 * 
 * * If the client calls without a transaction context, the Container throws the
 * javax.transaction.TransactionRequiredException exception if the client is a
 * remote client, or the javax.ejb.TransactionRequiredLocalException if the
 * client is a local client.
