I am trying to inject a JDBC DataSource into a servlet running on JBoss 5.0.0.GA The DataSource injection appears to work the first time the servlet is called (after deployment) and I get a Connection successfully. However, when the servlet is called the second time, I get an error: anonymous wrote : 16:53:59,687 ERROR [STDERR] org.jboss.util.NestedSQLException: You are trying to use a connection factory that has been shut down: ManagedConnectionFactory is null.; - nested throwable: (javax.resource.ResourceException: You are trying to use a connection factory that has been shut down: ManagedConnectionFactory is null.) | 16:53:59,687 ERROR [STDERR] at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:95) This is a test project for training purposes. I am using a mysql datasource thus: | <local-tx-datasource> | <jndi-name>bank</jndi-name> | <use-java-context>false</use-java-context> | <connection-url>jdbc:mysql://localhost:3306/bank</connection-url> | <driver-class>com.mysql.jdbc.Driver</driver-class> | <user-name>training</user-name> | <password>codeclass</password> | </local-tx-datasource> | and injecting into the servlet as follows: | @Resource(mappedName="bank") | private DataSource dataSource; | Either the datasource is timing out or I have misunderstood the lifecycle of dependency injection into servlets somehow. A straight lookup of the datasource works, incidentally, on each servlet call: | Context ctxt = new InitialContext(); | dataSource = (DataSource)(ctxt).lookup("bank"); | Clearly I've missed something important here. I've had similar issues injecting EJBs into servlets with JBoss 5 (i.e. works first time then fails subsequently) but I realise there are issues with this in any case. Any help gratefully appreciated. - Tom View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4213454#...
