I wrote a maven web service which refers to another project. The web service itself only contains 2 pom entries:
- jersey-container-servlet: 2.13
- native Project (Project 1)
web service POM:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Project 1, is also a maven Project and only has 1 pom entry, another native project (Let's call it Project 2).
Project 2 is again a maven project and its pom file contains 5 entries:
- lang-guess: 0.0.7
- Stanford-corenlp: 3.5.2
- stanford-corenlp: 3.5.2 : models
- mysql-connector-java : 5.1.34
- language-de: 3.0
The Web service runs perfectly on my local installed Tomcat 8 in Eclipse. However, when I export the web service from Eclipse (War file) and deploy it on my Tomcat server, I receive a java.lang.NoClassDefFoundError when I try to run the web service. I already tried several things I found on the net:
- Cleaning the project before building a war
- Maven update
- Setting %classpath% of my tomcat server to the project root directoy
- Adding both jars from Project 1 and Project 2 into tomcat/libs
- Removed all jars from the web service and deployed an incorrect (notrunning) project (Normally I should get a
ClassNotFoundExeceptionor similar?) - Add Project 1 to Deployment Assembly in Eclipse
In addition I read and tried many solutions already on several stackoverflow questions:
- java.lang.NoClassDefFoundError
- NoClassDefFoundError in web application running on Tomcat 7
- java.lang.NoClassDefFoundError: apache-tomcat-7.0.25
- Error: Servlet Jar not Loaded…
- validateJarFile(servlet-api.jar)
- exception in thread 'main' java.lang.NoClassDefFoundError:
- java.lang.NoClassDefFoundError when i run java file from terminal
- Setting up java classpath and java_home correctly in Ubuntu
All in all, nothing worked and the error java.lang.NoClassDefFoundError persist... I don't know what else to try so I am glad for any help! Thank you in advance :)
Mention able are maybe the server information:
- Tomcat Version: 8.0.30
- JVM Version: 1.8.0_66-b17
- OS: Linus (Ubuntu)
In addition, two other maven web services I wrote, successfully run on this server! So I think it could not be a server configuration problem?
Full stack trace is the following:

UPDATE: Due to the fact that I still found no solution, I simply copy pasted Project 1 and Project 2 to my web service. The web service still runs fine on localhost Tomcat but still the same crap NoClassDefFoundError error on Tomcat Server... Now I am REALLY REALLY out of ideas.
