Java spark framework enable logging

I'm building a java application with Spark framework with embedded Jetty and handlebars template engine.
But when i get an 500 Internal Error, the console didn't say anything.
I have added to my pom.xml the dependencies here: http://sparkjava.com/documentation.html#add-a-logger
but does not print all exceptions / errors (like errors 500)

Here my pom.xml dependecies

<dependencies>

<!-- FRAMEWORK: Spark -->
<dependency>
<groupId>com.sparkjava</groupId>

</dependency>

<artifactId>spark-template-handlebars</artifactId>

</dependency>

<dependency>

<artifactId>sql2o</artifactId>

</dependency>

<!-- DRIVERS: sqlite-->
<dependency>
<groupId>org.xerial</groupId>
<artifactId>sqlite-jdbc</artifactId>

</dependency>

<!-- LOGGER: slf4j -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.21</version>
</dependency>

</dependencies>


How i can enable all the logging for spark?

Answer

Use log4j to make a logging implementation. That's why you don't have an idea why are you getting an internal server error
