    #java.lang.NoClassDefFoundError: org/apache/commons/digester/Digester

    Stack Overflow | 2 years ago | sharath Yogananda
    java.lang.NoClassDefFoundError: org/apache/commons/digester/Digester error and I am stuck with this error for more than a month. I have tried all Digester versions available and I also checked for duplicate JARs in classpath. I have designed the report through iReport-5.6.0 and I used the JARs from the iReport-5.6.0\ireport\modules\ext and other required JARs. Error-Log: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/digester/Digester

    A few things cause this exception: 1) Check if you have all jars and if they're in the correct path when running. 2) Your classpath might be broken, you can define it in the command line with "java -cp yourClassPath" or at your IDE if you're using one.

    If you're using Hibernate, this indicates you're missing FasterXML Classmate dependency, which you can add with the following: <groupId>com.fasterxml</groupId> <artifactId>classmate</artifactId> <version>1.0</version>
