Hi, I've been having some issues setting up the DBAppender using a jndi DataSource supplied by TomEE. The datasource works fine in the application, but logback errors out when setting up its DBAppender with the same jndi location. Specifically JNDIConnectionSource.lookupDataSource throws a NamingException, which does the same lookup as my application code, but only the application code finds the datasource successfully. TomEE version 1.5.2 Logback classic 1.0.9 I've configured a DBAppender in logback.xml as so <appender name="DB" class="ch.qos.logback.classic.db.DBAppender"> <connectionSource class="ch.qos.logback.core.db.JNDIConnectionSource"> <jndiLocation>java:comp/env/jdbc/datasource</jndiLocation> </connectionSource> </appender> in web.xml <resource-ref> <res-ref-name>jdbc/datasource</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> in tomee context.xml <Resource name="jdbc/datasource" auth="Container" type="javax.sql.DataSource" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" maxActive="100" maxIdle="30" maxWait="10000" username="user" password="secret" driverClassName="oracle.jdbc.driver.OracleDriver" url="jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = localhost)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = SERVICE)))" /> and my application dataSource bean successfully finds the dataSource Context ctx = new InitialContext(); return (DataSource) ctx.lookup("java:comp/env/jdbc/datasource"); Please let me know if anymore information is needed. -- View this message in context: http://logback.10977.n7.nabble.com/DBAppender-fails-for-find-jndi-dataSource...
