Here is the code:
`package de.iit;
import org.apache.pulsar.client.api.Producer;
import org.apache.pulsar.client.api.PulsarClient;
import org.apache.pulsar.client.api.Schema;
public class Main {
public static void main(String[] args) {
try {
PulsarClient client = PulsarClient.builder()
.serviceUrl("pulsar://localhost:6650")
.build();
Producer<String> producer = client.newProducer(Schema.STRING)
.topic("my-topic")
.create();
producer.send("My message");
producer.close();
client.close();
} catch(Exception e) {
e.printStackTrace();
}
}
}`
Run with pulsar-client-all only:
`java -cp classes:lib/pulsar-client-all-2.5.1.jar de.iit.Main
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/pulsar/client/api/PulsarClient
`
Add pulsar-client-api:
`java -cp
classes:lib/pulsar-client-all-2.5.1.jar:lib/org.apache.pulsar-pulsar-client-api-2.5.1.jar
de.iit.Main
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/pulsar/shaded/com/google/protobuf/v241/UninitializedMessageException
`
Add protobuf:
`java -cp
classes:lib/pulsar-client-all-2.5.1.jar:lib/org.apache.pulsar-pulsar-client-api-2.5.1.jar:lib/org.apache.pulsar-protobuf-shaded-2.1.0-incubating.jar
de.iit.Main
Exception in thread "main" java.lang.NoClassDefFoundError:
org/slf4j/LoggerFactory
`
And so on... You should actually be able to check the content of
pulsar-client-all yourself:
`jar -t pulsar-client-all-2.5.1.jar`
And yes, I'm using the latest 2.5.1.
