I'm deploying Shibboleth IdP 3.1.1 on Tomcat 8.0.22, but I receive this error:

Information about the java version:
java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
I put in $CATALINA_HOME/lib the jars: slf4j-api-1.7.12.jar, slf4j-log4j12-1.7.12.jar and nlog4j-1.2.14.jar
But that does not solve the problem. I tried put org.slf4j as a dependency in maven, but don't work too.
Is there a way to resolve this exception? Thanks for any suggestion.
This mean you probably have two different librairies of slf4j in your war
org/slf4j/impl/StaticLoggerBinder, have different Class objects for the type LoggerFactory; used in the signature
You can use that command to find slf4j dependencies injected in your application.
mvn dependency:tree -Dverbose -Dincludes=commons-collections
resolving conflicts using the dependency tree
And Exclude dependancies in Maven:
<dependency>
[...]
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</exclusion>
</exclusions>
<dependency>
You can also unzip your war file and look in WEB-INF/lib/ to find the different versions of slf4j that you have.
This problem may be because there is a jar in the servlet container (Ex Tomcat).
For example:
- someone had kept some lib (In this case slf4j) in a tomcat's lib.
- you deployed a new project to that tomcat.
- In your new project, some of your dependencies have dependencies to that lib.
- Then there is duplicated of the same jar in Tomcat and WAR of your new project
Then you get such an error message.
The way to solve this is just use "scope" to say that it is provided.
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.6</version>
<scope>provided</scope>
</dependency>
By doing this, the WAR file will not include that dependency.

Problem solved. I used mvn dependency:tree to see the dependencies:

If you are using spring-boot-starter-web-1.5.1.RELEASE.jar,then you need to exclude jul-to-slf4j-1.7.22.jar,jcl-over-slf4j-1.7.22.jar.These two jar have conflict slf4j-api.
