I am trying to deploy sample Java EE Cargo Tracker application
https://github.com/javaee/cargotracker
I am able to deploy it by executing maven, which build project completely
mvn package cargo:run
However when I am trying to deploying application from IntelliJ Idea on Glassfish 4.1.12 I am getting
Internal Exception: java.lang.NoClassDefFoundError:
org/apache/commons/lang3/Validate. Please see server.log for more details.
My pom contains
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.6</version>
<scope>compile</scope>
</dependency>
Tried 3.4 and 3.6, does not help, application fails to deploy with above error
This is configuration of artifact in IntelliJ IDEA

may be old or previous dependency occurring the issue so delete .m2 folder and use commons-lang3 version 3.5 update maven project and rebuild it and run it.
I have a Java project that is running on a local Liberty Server on eclipse. I am trying to use a Cloudant database.
If I run a test file using the database in the project as a Java Application, everything is fine, but when running the project on the Liberty Server, I get this error:
`[ERROR ] SRVE0777E: Exception thrown by application class 'org.apache.cxf.service.invoker.AbstractInvoker.createFault:162'
org.apache.cxf.interceptor.Fault: com/cloudant/client/api/ClientBuilder
at org.apache.cxf.service.invoker.AbstractInvoker.createFault(AbstractInvoker.java:162)
at [internal classes]
Caused by: java.lang.NoClassDefFoundError: com/cloudant/client/api/ClientBuilder
at com.example.Testdb.createClient(Testdb.java:77)`
But the ClientBuilder is already added as a maven dependency in the pom.xml file:
<dependency>
<groupId>com.cloudant</groupId>
<artifactId>cloudant-client</artifactId>
<version>2.6.2</version>
<scope>provided</scope>
</dependency>
The .jar file is also included in the Java Build Path.
What can I do to eliminate the NoClassDefFoundError?
I am trying to initialize firebase in Google appengine web app and using maven for dependencies.
<dependency>
<groupId>com.google.firebase</groupId>
<artifactId>firebase-server-sdk</artifactId>
<version>[3.0.0,)</version>
</dependency>
Getting error
java.lang.NoSuchMethodError: com.google.api.client.googleapis.auth.oauth2.GoogleCredential.fromStream(....)
at com.google.firebase.FirebaseOptions$Builder.setServiceAccount(FirebaseOptions.java:77)
How to solve this issue:
Go to http://search.maven.org/#search%7Cga%7C1%7Cgoogle-api-client and find the last version of com.google.api-client API.
Add the dependency on you project
<dependency>
<groupId>com.google.api-client</groupId>
<artifactId>google-api-client-assembly</artifactId>
<version>last version </version>
</dependency>
I do this on EJB project using netbeans and glassfish server, so I download the jar file of the last version com.google.api-client add it on Netbeans Libraries and glassfish libraries, then I compile the project and restart glassfish.
I've included the Maven based project into my application, added Deployment Assembly which shows that the .jar file gets copied to WEB-INF/lib/ImportedProject.jar.
Problem occurs when imported lib wants to reference the lib that it is using which, apparently, does not get included inside the ImportedProject.jar.
Example:
ImportedProject pom.xml has:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.12</version>
</dependency>
When I add ImportedProject.jar to my Non-Maven project and run it, I get exception:
threw exception [Servlet execution threw an exception] with root cause
java.lang.ClassNotFoundException: org.slf4j.LoggerFactory
My question is: How to add both that Maven project and its dependencies?
maven dependency plugin helps to get required project library with it's dependencies.
So, If you would like to add POM based project on NON-POM based project, all you would do is to execute mvn dependency:copy-dependencies command and you will have all dependencies on target/dependencies folder. Copy all jar from dependencies and paste to WEB-INF/lib directory.
I am getting the error as mentioned below, while running the feed utility. I am trying to load an image "logo.png". The slf4j jar file is also available in the runtime classpath. But still I am getting this error.

Add a SLF4J implementation (as you only have its API):
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.26</version>
</dependency>
You have to provide one of the various SLF4J implementation .jar files in the classpath, as well as the interface .jar file. This is documented.
Download slf4j-1.7.5.zip
It holds different jar files.
Go to -> Integration folder after extracting zip and include following jar files
slf4j-api-2.0.99
slf4j-simple-1.6.99
junit-3.8.1
Right click on project properties and follow below steps Project Properties" --> "Deployment Assembly", adding "Java Build Path Entries -> Maven Dependencies
I tried other solutions and the exception didn't go away. So I decompiled the entire jose4j 0.6.5 jar with a Java Decomplier and look at its pom.xml.
I realised it has a specific dependency on slf4j-api, version 1.7.21:
So in my project's pom.xml, I added the exact same dependency, updated my Maven project so that it downloads this jar into my repository and the exception was gone.
However it may bring up another error caused by slf4j itself:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
To overcome this issue, I added the following into my project's pom.xml. So altogether you need to add the following to your pom.xml and my jose4j ran without anymore issues:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.21</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.6.4</version>
</dependency>
Remember to update your Maven project after amending your pom.xml.
(Right-click Project folder in Eclipse -> Maven -> Update Project..)
I also had the similar problem. I had a maven project and was testing rabbitmq. Firstly it showed me the similar error then I added all the SLF4J dependencies in the maven project and then error changed to "Maven SLF4J: Class path contains multiple SLF4J bindings". Here is the complete list of dependencies from pom.xlm
<dependencies>
<dependency>
<groupId>com.rabbitmq</groupId>
<artifactId>amqp-client</artifactId>
<version>4.0.0</version>
</dependency>
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.0</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.21</version>
<scope>compile</scope>
</dependency>
</dependencies>
It worked finally.
I was facing a similar issue and below line fixed the issue for me.
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</dependency>
Edit: I realized that I was using spring boot and the version of the dependency was getting pulled from spring-boot-starter-parent.
To be more specific if you are missing the class com.vaadin.external.org.slf4j.LoggerFactory add the below dependency.
<dependency>
<groupId>com.vaadin.external.slf4j</groupId>
<artifactId>vaadin-slf4j-jdk14</artifactId>
<version>1.6.1</version>
</dependency>
If you are missing any other org.slf4j.LoggerFactory, just go to Maven central class name search and search for the exact class name to determine what exact dependency you are missing.
You can use bellow dependency
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.7</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.7</version>
</dependency>
Add the following jars to the class path or lib folder
slf4j-api-1.7.2.jar
slf4j-jdk14-1.7.2.jar
The perfect solution which works undoubtedly is to just add these packages to your app:
https://mvnrepository.com/artifact/org.slf4j/slf4j-api/1.7.2
http://archive.apache.org/dist/logging/log4j/1.2.16/
after adding so you may encounter following WARNING which you can simply ignore!
SLF4J: No SLF4J providers were found.
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#noProviders for further details.

This error occurs because of referenced jars are not checked in our project's order and export tab.
Choose Project ->ALT+Enter->Java Build Path ->Order and Export->check necessary jar files into your project.
Finally clean your project and run.It will run successfully.
When we use the slf4j api jar, we need any of the logger implementations like log4j. On my system, we have the complete set and it works fine.
1. slf4j-api-1.5.6.jar
2. slf4j-log4j12-1.5.6.jar
3. **log4j-1.2.15.jar**
I believe the answer is outlined on the slf4j web-site (Failed to load class org.slf4j.impl.StaticLoggerBinder)
For a very quick solution I suggest adding no-operation (NOP) logger implementation (slf4j-nop.jar)
For example, if using maven:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-nop</artifactId>
<version>${slf4j-nop-version}</version>
</dependency>
I have the same issue for zookeeper start up.
# sh /opt/zookeeper-3.4.13-1.hardtop.0.9.1/bin/zkServer.sh start-foreground
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.13-1.hardtop.0.9.1/bin/../conf/zoo.cfg

But the class is already there as part of other slf4j jars:
# grep LoggerFactory lib/*jar
Binary file lib/log4j-1.2-api-2.17.1.jar matches
Binary file lib/log4j-slf4j-impl-2.17.1.jar matches
Binary file lib/netty-all-4.1.30.Final.jar matches
make sure your MANIFEST.MF contains the name of the referenced jar in my application was slf4j-api-*. jar.
You need slf4j-api library. For most cases only slf4j-api and slf4j-jkd14 are only required:
Here you can download the version 1.7.2:
slf4j-api-1.7.2.jar
slf4j-jkd14-1.7.2jar
If you need an example to see how these are used, refers to this tutorial:
http://www.ibm.com/developerworks/java/library/j-hangman-app/index.html
All the code for the tutorial is available
get the compatible version of this jar slf4j-jdk14 and add it as a dependency.
this solved the problem for me.
You need slf4j-api library and slf4j-log4j12-1.7.25 jar. Copy this jars in your project-> WEBINF-> lib folder and in tomcat server lib folder to execute successfully.
When you copy dependency from maven repository there is:
<scope>test</scope>
Try to remove it from dependencies in pom.xml like this.
<!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-classic -->
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.2.3</version>
</dependency>
This works for me. I hope it would be helpful for someone else.
this worked for me /properties/maven uncheck resolve dependencies from Workspace projects.
First, check the dependency hierarchy than to exclude all slf4j jars from other dependencies and add separate slf4j as dependencies.
If it is not maven project then make sure the jar file is inside the project folder. If it is a maven project then make sure it's in the pom.xml.
use maven it will download all the required jar files for you.
in this case you need the below jar files:
slf4j-log4j12-1.6.1.jar
slf4j-api-1.6.1.jar
These jars will also depend on the cassandra version which you are running.
There are dependencies with cassandra version , jar version and jdk version you use.
You can use : jdk1.6
with : cassandra 1.1.12
and the above jars.
If you are facing java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory
Add slf4j-log4j12 jar in the library folder of the project
The LoggerFactory class is msising according to the error message:
java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory
Apparently, the slf4j.jar file is not getting loaded for some reason.
