Examples with RemoteBeanInterface org.jboss.as.quickstarts.ejb.server.RemoteBeanInterface used on opensource projects

Example 6 with RemoteBeanInterface

use of org.jboss.as.quickstarts.ejb.server.RemoteBeanInterface in project quickstart by wildfly.

the class RemoteBeanCaller method remoteOutboundStatefulNoTxBeanCall.

/**
 * <p>
 * The method calls the remote EJB {@link javax.ejb.Stateful} endpoint.
 * </p>
 * <p>
 * To lookup the remote endpoint is used remote outbound connection defined in the <code>standalone.xml</code> configuration file.
 * The deployment links to the configuration by descriptor <code>WEB-INF/jboss-ejb-client.xml</code>.
 * </p>
 *
 * <p>
 * This demonstrates what happens on two subsequent calls to the stateful bean when no transaction is started.
 * In fact, for stateful bean the demonstrated behaviour makes no difference if the transaction is or is not started.
 * </p>
 * <p>
 * As there are processed two remote EJB invocations and we talk about stateful bean the EJB client has to ensure
 * that both calls ends at the same remote server.
 * The demonstration does not make much sense when there is started only one instance of the remote server (<code>server2</code>).
 * But in case there are two remote servers started (two instances of <code>server2</code> are run)
 * then the second EJB invocation has to be directed to the same server as the first one.
 * </p>
 *
 * @return list of strings as return values from the remote beans,
 *         in this case the return value are hostnames and the jboss node names of the remote application server
 * @throws NamingException when remote lookup fails
