Subject Re: Accessing a server-wide JDBC data source through JNDI from a web module
Date Thu, 01 Oct 2009 14:43:59 GMT

Hallo,

I have the same problem with my EJB-Project.


Standalone EJB:


Code: 

public class LogBean implements LogInterfaceLocal, LogInterfaceRemote {
@Resource(name = "jdbc/jlog4ssisDS")
    private DataSource _dbsource;
    private Connection _dbconnect;
    
    @PostConstruct
    public void initialize() {
        try {
            _dbconnect = _dbsource.getConnection();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }



openejb-jar.xml:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<openejb-jar xmlns="http://www.openejb.org/xml/ns/openejb-jar-2.2"
	xmlns:nam="http://geronimo.apache.org/xml/ns/naming-1.2"

	xmlns:sec="http://geronimo.apache.org/xml/ns/security-1.2"

			<sys:version>1.0</sys:version>
			<sys:type>car</sys:type>

				<sys:version>1.0</sys:version>
				<sys:type>rar</sys:type>
			</sys:dependency>
		</sys:dependencies>
	</sys:environment>
</openejb-jar>





EJB in Enterprise Application Project


code:

public class TimerSettings {
    @Resource(name = "jdbc/forceDS")
    private DataSource      _dbsource;
    private Connection      _dbconnect;

    public void getSettings() {
            _dbconnect = _dbsource.getConnection();
    }
