NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder

I'm trying to run the sample tiles example given here.

Below is my POM.xml:

<dependencies>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>3.8.1</version>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>org.apache.tiles</groupId>
			<artifactId>tiles-api</artifactId>
			<version>2.1.2</version>
		</dependency>
		<dependency>
			<groupId>org.apache.tiles</groupId>
			<artifactId>tiles-core</artifactId>
			<version>2.1.2</version>
		</dependency>
		<dependency>
			<groupId>org.apache.tiles</groupId>
			<artifactId>tiles-jsp</artifactId>
			<version>2.1.2</version>
		</dependency>
		<dependency>
			<groupId>org.slf4j</groupId>
			<artifactId>slf4j-api</artifactId>
			<version>1.5.2</version>
		</dependency>

When I'm trying to run the example the below error is thrown:

Sep 17, 2010 11:59:43 PM org.apache.catalina.core.StandardContext listenerStart

Any idea?

I spent 30 minutes googling for this but could not find a possible sollution.

Please help me...

You have included a dependency on the SLF4J API, which is what you use in your application for logging, but you must also include an implementation that does the real logging work.

For example to log through Log4J you would add this dependency:

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.5.2</version>
    </dependency>

The recommended implementation would be logback-classic, which is the successor of Log4j, made by the same guys that made SLF4J and Log4J:

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>0.9.24</version>
</dependency>

Note: The versions may be incorrect.

You have included the dependency for sflj's api, but not the dependency for the implementation of the api, that is a separate jar, you could try slf4j-simple-1.6.1.jar.

Add the all tiles jars like(tiles-jsp,tiles-servlet,tiles-template,tiles-extras.tiles-core ) to your server lib folder and your application build path then it work if you using apache tailes with spring mvc application

Copy all order entries of home folder .iml file into your /src/main/main.iml file. This will solve the problem.

i had the same error while working with hibernate, i had added below dependency in my pom.xml that solved the problem

	<dependency>
		<groupId>org.slf4j</groupId>
		<artifactId>slf4j-api</artifactId>
		<version>1.7.10</version>
	</dependency>

reference https://mvnrepository.com/artifact/org.slf4j/slf4j-api

A good practice to ensure consistency of SL4J versions is to centralize the version in a property like this:

...
    <properties>
		<org.slf4j.version>1.5.2</org.slf4j.version><!-- SLF4J release -->
 	</properties>
...
     <dependencies>
		<!-- SL4J with LOG4J implementation -->
		<dependency>
			<groupId>org.slf4j</groupId>
			<artifactId>slf4j-api</artifactId>
			<version>${org.slf4j.version}</version>
		</dependency>
		<dependency>
			<groupId>org.slf4j</groupId>
			<artifactId>slf4j-log4j12</artifactId>
			<version>${org.slf4j.version}</version>
		</dependency>
...
