NetLicensing Demo: Class not found error

[r-brown]

After adding NetLicensing dependency to the pom.xml

  <dependency>
    <groupId>com.labs64.netlicensing</groupId>
    <artifactId>netlicensing-client</artifactId>
    <version>2.3.8</version>
  </dependency>

I'm getting following error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/glassfish/jersey/client/ClientConfig

Using netlicensing-client dependency in IDE

Usually, your IDE (Eclipse or IntelliJ IDEA) is able to resolve all transitive dependencies of netlicensing-client.
Therefore all needed 3pp libraries and classes will be available in the classpath.

Using netlicensing-client dependency with Maven and CLI

Here is a step by step guideline on how to run NetLicensing Demo.

Preconditions

• Java 1.7 or higher
• Maven 3

1. Download NetLicensing Demo source code

Open NetLicensing releases and download latest released version.

2. Open project

Extract ZIP file and navigate to the NetLicensingClient-java/NetLicensingClient-demo folder

3. Prepare demo module

In order to isolate demo module from the parent maven module, please modify pom.xml accordingly:

• add netlicensing-client dependency
• remove parent module relationship

You can use following POM file as an example:

<?xml version="1.0" encoding="UTF-8"?>
<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">

                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <createDependencyReducedPom>false</createDependencyReducedPom>
                    <transformers>
                        <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                            <mainClass>com.labs64.netlicensing.demo.NetLicensingClientDemo</mainClass>
                        </transformer>
                    </transformers>
                </configuration>
            </plugin>
        </plugins>
    </build>

    <dependencies>
        <dependency>
            <groupId>com.labs64.netlicensing</groupId>
            <artifactId>netlicensing-client</artifactId>
            <version>2.3.8</version>
            <scope>compile</scope>
        </dependency>
    </dependencies>

</project>
