Avoiding NoClassDefFoundError when using JavaMail [duplicate]

This question already has answers here:
Replacements for deprecated JPMS modules with Java EE APIs
(11 answers)
Closed 4 years ago.
I keep getting the NoClassDefFoundError error. I am trying to send an email using the JavaMail API, but the error occurs when I'm creating an instance of Message using the SMTPMessage class.
I know I need the activation library, but it still doesn't work.
By the way, I'm using JDK 10.
The error happens on the first line of this code.
#Override
public void sendEmail(Mail mail) throws MessagingException
{
Message message = new SMTPMessage(this.session);
message.setSubject(mail.getHeader());
message.setFrom(mail.getFrom());
message.setSentDate(mail.getDateClone());
if (mail.getSignature() != null)
message.setText(mail.getText() + "\n\n" + mail.getSignature());
else
message.setText(mail.getText());
Transport.send(message);
}

Solution
Just add the activation library to your own class path. You can put it in your own package.

Multiple Jar file not found issues with IBM watson personality Insights

I'm writing a watson program to fetch personality traits. However, I'm running into errors with jar file issues.
import com.ibm.watson.developer_cloud.personality_insights.v3.PersonalityInsights;
import com.ibm.watson.developer_cloud.personality_insights.v3.model.Profile;
public JSONArray getPersonalityTraitsFromWatson(String text) {
JSONArray retval = null;
PersonalityInsights service = new PersonalityInsights("2016-10-20", "xxxx", "yyyy");
Profile response = service.getProfile(text).execute();
System.out.println("profile: " + response);
return retval;
}
The first problem is with okhttp3. I get a classnotfound error with JavaNetCookieJar. I'm currently using okhttp3 and javanetcookiejar is missing in it. I picked up the okhttp3 from MVNRepository.

I tried using "org.apache.servicemix.bundles.okhttp-3.2.0_1.jar" with and with the okhttp3.jar which clears the JavaNetCookieJar error but throws an SSLSocketFactory error (given below)
okhttp3.OkHttpClient$Builder.sslSocketFactory(Ljavax/net/ssl/SSLSocketFactory;Ljavax/net/ssl/X509TrustManager;)

Found the problem, the okhttp-urlconnection-3.8.1.jar & logging-interceptor-3.8.1.jar were required to be added. This fixed the problem.

Javafx NullPointerException when Playing Sounds [duplicate]

This question already has an answer here:
How do I determine the correct path for FXML files, CSS files, Images, and other resources needed by my JavaFX Application?
(1 answer)
Closed 2 years ago.
I am working on a Javafx game and have been attempting to implement some sound using the following code:
URL laserResource = getClass().getResource("LaserBlast.wav");
AudioClip laserPlayer = new AudioClip(laserResource.toString());
This code is instantiated in the main class before any methods. I have a module called JavaFxImages which contains all my resources including my sounds and I have been successfully able to access images for ImageView from the folder through code such as Image asteroid = new Image("Asteroid.png");.
However, when I run my game I get a NullPointerException at the line for my audio clip. I have spent the past many hours researching and trying every different way to access this resource. I've tried many permutations of the URL ("JavaFxImages/LaserBlast.wav", Desktop/JavaFxImages/LaserBlast.wav", etc.), but every time it has the same error. I'm really at a loss for what is wrong with the code. I would greatly appreciate any help that can be given.
Thanks in advance!
The full error message is given below.

Your error mostly happens on Itellij IDEA - Javafx Project
Instead of:
URL laserResource = getClass().getResource("LaserBlast.wav");
AudioClip laserPlayer = new AudioClip(laserResource.toString());
Use:
//By default your Package_NAME is: sample
File laserResource = new File("src/Package_NAME/LaserBlast.wav");
AudioClip laserPlayer = new AudioClip(laserResource.toURI().toString());

Infinispan MongoDb CacheStore Exception [duplicate]

Exception using mongodb as infinispan cache store
(1 answer)
Closed 8 years ago.
I want to use MongoDb as cachestore for Infinispan but getting following exception
It is different form the question Exception using mongodb as infinispan cache store
since the method b.loader() is not availabe in infinispan 7.0 jar i just figured out the turn around by using b.persistence.addStore() but still getting the exception as mentioned in the question
Code--
ConfigurationBuilder b = new ConfigurationBuilder();
b.loaders().addStore(
MongoDBCacheStoreConfigurationBuilder.class).host( "localhost" )
.port( 27017 )
.timeout( 1500 )
.acknowledgment( 0 )
.username( "mongoDBUSer" )
.password( "mongoBDPassword" )
.database( "infinispan_cachestore" )
.collection( "entries" );
final Configuration config = b.build();
MongoDBCacheStoreConfiguration store = (MongoDBCacheStoreConfiguration) config.loaders().cacheLoaders().get(0);
EmbeddedCacheManager cacheManager=new DefaultCacheManager();
cacheManager.defineConfiguration("usersCache", config);
//DefaultCacheManager manger=new DefaultCacheManager(config);
Cache<String, String> usersCache = cacheManager.getCache("usersCache");

Download infinispan-cachestore-mongodb-5.3.0.final.jar and import it into your project and be sure to import the package inside the class that uses it.
