Logback doesn't log into file

I'm using logback in my project and it doesn't log into a file.

My logback.xml looks like this

<property file="api.properties"/>

<appender name="FILE-AUDIT"
          class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>c:/debug.log</file>
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <Pattern>
            %d{yyyy-MM-dd HH:mm:ss} - %msg%n
        </Pattern>
    </encoder>

    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <!-- rollover daily -->
        <fileNamePattern>c:/archived/debug.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
        <timeBasedFileNamingAndTriggeringPolicy
                class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>10MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
    </rollingPolicy>

</appender>

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
    <encoder>
        <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{5} - %msg%n</pattern>
    </encoder>
</appender>

<logger name="JDBC" level="INFO" additivity="false">
    <appender-ref ref="STDOUT" />
    <appender-ref ref="FILE-AUDIT" />
</logger>
<logger name="RESTSecurity" level="INFO" additivity="false">
    <appender-ref ref="STDOUT" />
    <appender-ref ref="FILE-AUDIT" />
</logger>
<logger name="models" level="INFO" additivity="false">
    <appender-ref ref="STDOUT" />
    <appender-ref ref="FILE-AUDIT" />
</logger>

<!-- Strictly speaking, the level attribute is not necessary since -->
<!-- the level of the root level is set to DEBUG by default.       -->
<root level="DEBUG">
    <appender-ref ref="STDOUT" />
</root>

and it's placed in WEB-INF/classes.

I use these dependencies 

  <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>${logback.version}</version>
        </dependency>

        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-core</artifactId>
            <version>${logback.version}</version>
        </dependency>

When I run my app on WebLogic server I get my log messages in the console but it doesn't create log files. Anyone know what could be wrong?

EDIT: I tried using both 

private static final Logger logger = LoggerFactory.getLogger("JDBC");

and 

private static final Logger logger = LoggerFactory.getLogger(Roles.class);

as that class is in JDBC package. Then I just do 

 logger.info("Initializing roles");

EDIT2: Because log messages i get in console looks different from what is in logback.xml it looks like it does ignore my logback.xml at all.

The problem must come from Weblogic which does not pick up SLF4J/Logback from your classpath.

Add the following prefer-application-packages to your weblogic.xml :

<prefer-application-packages>
    <package-name>org.slf4j.*</package-name>
    <package-name>ch.qos.logback.*</package-name>
</prefer-application-packages>

You have to add all the appenders to the log level, if you want DEBUG to log to file, add the ref like this:

<root level="DEBUG">
    <appender-ref ref="STDOUT" />
    <appender-ref ref="FILE-AUDIT" />
</root>
