I am getting ClassNotFoundException and NoClassDefFoundError exceptions when I attempt to run my application using a maven defined dependency.
I added my maven dependency for the jar in question to my pom.xml file with the following declaration:
<dependency>
<groupId>ldap</groupId>
<artifactId>com.novell.ldap</artifactId>
<systemPath>${local.lib.dir}/ldap.jar</systemPath>
<scope>system</scope>
<version>1</version>
</dependency>
The jar is correctly added to the Dependencies NetBeans project
But when I deploy the app the dependency is missing
java.lang.NoClassDefFoundError: com/novell/ldap/LDAPException
If you read the Maven documentation about this scope, it seems the expected behavior if your application server doesn't provide this library at runtime:
This scope is similar to provided except that you have to provide the JAR which contains it explicitly.
The provided scope states :
This is much like compile, but indicates you expect the JDK or a container to provide the dependency at runtime.
Not advised solution : add this library in the lib folder of your application server.
Cleaner solution : add this maven dependency in your maven repositories manually or with mvn install:install-file.
And remove the system scope of this dependency. It will use the default scope.
