Hi there, I’m trying to log into Oracle database tables using DBAppender and JNDIConnectionSource. I created the needed tables for logging as mentioned in documentation. I want to use connection pooling and the JNDI variant for getting the pool. Here’s my configuration: -JBoss 7.0.2 (the complete one, not the web profile) -Oracle DB 11g -logback-classic 0.9.29 -ojdbc 11.2.0.2.0 I configured the following things: In JBoss: -A new module for Oracle JDBC drivers -A new connection pool using Oracle JDBC drivers in the modules segment of JBoss      In standalone.xml:               <datasource jndi-name="java:/myLog" pool-name="myLogPool" enabled="true" jta="true" use-java-context="true" use-ccm="true">                     <connection-url>                         jdbc:oracle:thin:@127.0.0.1:1521:orcl                     </connection-url>                     <driver>                         oracle                     </driver>                     <transaction-isolation>                         TRANSACTION_READ_COMMITTED                     </transaction-isolation>                     <pool>                         <prefill>                             true                         </prefill>                         <use-strict-min>                             false                         </use-strict-min>                         <flush-strategy>                             FailingConnectionOnly                         </flush-strategy>                     </pool>                     <security>                         <user-name>                             log                         </user-name>                         <password>                             secretPassw0rd                         </password>                     </security>                 </datasource> -logback-classic.jar and it's dependencies are being shipped with my .ear file. In logback.xml: ... <appender name="DBAppender" class="ch.qos.logback.classic.db.DBAppender">          <connectionSource class="ch.qos.logback.core.db.JNDIConnectionSource">                    <param name="jndiLocation" value="java:/myLog" />          </connectionSource> </appender> ... <root>          <appender-ref ref="DBAppender" /> </root> I have also configured a RollingFileAppender and a ConsoleAppender. They both work fine on my JBoss. In the server.log from JBoss you can see that he successfully published my data source myLog under java:/myLog. I can't see any problems occurring due to logging from JBoss. No problems with logging via logback are mentioned. But when my application starts logging, the entries are logged to console and the file appender, but nothing is written to the database. I have a second connection pool configured in JBoss for my application. That one is working fine. I can't figure out what the problem is. Please help me. Regards, Henning
