Hi! We are using JBoss 4.0.5 GA - ejb3, Hibernate 3.2. Is there a way to implement singleton MDB with ejb3?
We tried | @ActivationConfigProperty(propertyName = "maxSession", propertyValue = "1") | but it did not work... We have two problems at the moment of which one is that our program tries to connect database with connection already being used. We believe that this is related to there being more than one MDB. Another problem is that we get too many connections to database. We get these Exceptions while connecting... | 2007-01-23 13:57:58,817 DEBUG [fi.logiasoftware.jca.adapter.GenericManagedConnection] GenericManagedConnection destroy() | 2007-01-23 13:57:58,817 DEBUG [fi.logiasoftware.jca.adapter.GenericManagedConnection] handler [EMAIL PROTECTED] | 90 for [EMAIL PROTECTED] | 2007-01-23 13:57:58,817 DEBUG [fi.logiasoftware.jca.handlers.FTPProtocolHandler] FTPProtocolHandler boolean isConnected() | 2007-01-23 13:58:08,971 WARN [fi.logiasoftware.jca.handlers.FTPProtocolHandler] 49 IOException in connect() : Read timed out | 2007-01-23 13:58:08,972 WARN [fi.logiasoftware.jca.handlers.FTPProtocolHandler] 49Could not connect to 192.194.71.123:21. | 2007-01-23 13:58:08,972 WARN [org.jboss.resource.connectionmanager.JBossManagedConnectionPool] Unable to fill pool | javax.resource.ResourceException: fi.logiasoftware.jca.common.ProtocolHandlerException: 49Could not connect to 192.194.71.123:21. | at fi.logiasoftware.jca.adapter.GenericManagedConnectionFactory.createManagedConnection(GenericManagedConnectionFactory.java:137) | at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.createConnectionEventListener(InternalManagedConnectionPool.java:565) | at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.fillToMin(InternalManagedConnectionPool.java:512) | at org.jboss.resource.connectionmanager.PoolFiller.run(PoolFiller.java:74) | at java.lang.Thread.run(Thread.java:797) | Caused by: | fi.logiasoftware.jca.common.ProtocolHandlerException: 49Could not connect to 192.194.71.123:21. | at fi.logiasoftware.jca.handlers.FTPProtocolHandler.connect(FTPProtocolHandler.java:119) | at fi.logiasoftware.jca.adapter.GenericManagedConnectionFactory.createManagedConnection(GenericManagedConnectionFactory.java:126) | ... 4 more | 2007-01-23 13:58:08,978 DEBUG [fi.logiasoftware.jca.adapter.GenericManagedConnectionFactory] GenericManagedConnectionFactory createManagedConnection( | Subject subject, ConnectionRequestInfo o) | 2007-01-23 13:58:08,978 DEBUG [fi.logiasoftware.jca.adapter.GenericManagedConnection] GenericManagedConnection GenericManagedConnection(ManagedConnec | tionFactory) | 2007-01-23 13:58:08,979 DEBUG [fi.logiasoftware.jca.adapter.GenericManagedConnection] GenericManagedConnection setConnection(AbstractProtocolHandler | handler) | 2007-01-23 13:58:08,979 DEBUG [fi.logiasoftware.jca.adapter.GenericManagedConnection] GenericManagedConnection addConnectionEventListener(ConnectionE | ventListener arg0) | 2007-01-23 13:58:08,979 TRACE [org.jboss.resource.connectionmanager.JBossManagedConnectionPool] Filling pool cl=org.jboss.resource.connectionmanager. | [EMAIL PROTECTED] [EMAIL PROTECTED] handles=0 las | tUse=1169553488979 permit=false trackByTx=false mcp=null [EMAIL PROTECTED] | 2007-01-23 13:58:08,979 DEBUG [fi.logiasoftware.jca.adapter.GenericManagedConnectionFactory] GenericManagedConnectionFactory createManagedConnection( | Subject subject, ConnectionRequestInfo o) | | Any help would be appreciated!
