Quelqu'un peut-il m'aider avec ça? Je l'ai lu http://dev.mysql.com/doc/refman/5.0/en/connector-j-reference-replication-connection.html et créé une source de données JBoss avecClassCastException utilisant MySQL ReplicationDriver dans une application JBoss?
<connection-url>jdbc:mysql:replication://sys1:3306,sys2:3306,sys3:3306/mydb</connection-url>
<driver-class>com.mysql.jdbc.ReplicationDriver</driver-class>
Dans mon code JBoss, quand j'exécutez la commande suivante (sur un nœud esclave)
Context initCtx = new InitialContext();
DataSource ds = (DataSource) initCtx.lookup(...);
conn = ds.getConnection();
conn.setReadOnly(false);
conn.prepareStatement(...);
L'appel prepareStatement produit la trace de la pile suivante :
2010-09-16 18:45:31,129 WARN [org.jboss.resource.connectionmanager.TxConnectionManager] (ajp-127.0.0.1-8009-2) Connection error occured: org.jboss.resource.[email protected]1b576f8[state=NORMAL [email protected]11a3ce4 handles=1 lastUse=1284659131129 permit=true trackByTx=false mcp=org.jbos[email protected]193a581 context=org[email protected]56e1fe xaResource=org.jboss[email protected]f058a txSync=null]

J'ai cherché des réponses mais je ne trouve personne avec un problème similaire. Est-ce que je manque l'évidence ???
Merci
