It says i need guava's version to be over 16, but I'm using guava 19. I even did mvn dependency:tree to check if something else is using guava, but there's only that version.
@Named(value = "glicoseChart")
@Dependent
public class GlicoseChart implements Serializable{
private LineChartModel glicoseModel;
public LongTermPersistence longTerm;
@PostConstruct
public void init() {
createLineModels();
}
public LineChartModel getGlicoseModel() {
return glicoseModel;
}
private void createLineModels() {
glicoseModel = initLinearModel();
}
private LineChartModel initLinearModel()
{
LineChartModel model = new LineChartModel();
longTerm = new LongTermPersistence();
// VVVVVVVVVVVVV
longTerm.connectB();
It gives an error trying to connect. And the connection code:
public void connectB()
{
this.cluster = Cluster.builder()
.addContactPoint("127.0.0.1")
.withPort(9042)
.build();
session = cluster.connect();
}
It gives an error trying to build the cluster. However, if I try to connect in another class, and not in the managed bean, it works just fine.
However, inside the managed bean, i get this error:
Caused by: com.datastax.driver.core.exceptions.DriverInternalError: Detected incompatible version of Guava in the classpath. You need 16.0.1 or higher. at com.datastax.driver.core.GuavaCompatibility.selectImplementation(GuavaCompatibility.java:138) at com.datastax.driver.core.GuavaCompatibility.(GuavaCompatibility.java:52)
The thing is, i'm using guava-19.0, and it's saying im using 16 below, which is not true, since I can use that piece of code in another class' main. I'm using cassandra 3 btw.
You should use the same guava version as your cassandra-driver-core dependency, to be safe. Eg cassandra-driver-core 3.0.0 uses guava 16.0.1
See https://mvnrepository.com/artifact/com.datastax.cassandra/cassandra-driver-core
The error message only guesses your guava version.
