SLF4JBridgeHandler installation via logging.properties configuration file doesn't work

Question

I have a project and I use:

• Apache Maven 3.3.3
• Project Jersey 1.17
• Spring 3.3.1
• Tomcat 6
• Eclipse IDE

I need to log requests and responses. To achieve it I added LoggingFilter to my web.xml:

<init-param>
     <param-name>com.sun.jersey.spi.container.ContainerRequestFilters</param-name>
     <param-value>com.sun.jersey.api.container.filter.LoggingFilter</param-value>
 </init-param>
 <init-param>
     <param-name>com.sun.jersey.spi.container.ContainerResponseFilters</param-name>
     <param-value>com.sun.jersey.api.container.filter.LoggingFilter</param-value>
 </init-param>

I run project in Eclipse and see logging at the Eclipse Console.

Now, I want to use Logback to write log files and to use custom appenders, so I added to my pom.xml:

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.1.3</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.13</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jul-to-slf4j</artifactId>
    <version>1.7.13</version>
</dependency>

To route all JUL log records to the SLF4J API, I use org.slf4j.bridge.SLF4JBridgeHandler

I tried to install SLF4JBridgeHandler by creating src/main/resources/logging.properties with the content:

handlers = org.slf4j.bridge.SLF4JBridgeHandler

as it mentioned here and nothing was happening.

If I use another approach (Programmatic installation) everything works fine.

Why doesn't it work with logging.properties config? What did I miss?

Answer 1

The logging.properties file should reside on the filesystem (not on class path). And it's path should be specified via system property java.util.logging.config.file:

java -Djava.util.logging.config.file=/path/to/logging.properties ...
