java.lang.NoClassDefFoundError: com.twilio.Twilio - web

Question

For some reason Twilio SMS works only in a public static void main function as shown here. When I try to move it to a JSF environment shown here it gives me an error saying "NoClassDefFoundError" which means the class was not found in the classpath. The strange this both the working and not working twilio are in the same project which puzzles me. I'm unsure of how to solve it.
Working Code
package twilio;
import com.twilio.Twilio;
import com.twilio.type.PhoneNumber;
import com.twilio.rest.api.v2010.account.Message;
import javax.faces.bean.ManagedBean;
#ManagedBean
public class TwilioMSG {
public static final String ACCOUNT_SID = "myAccSid";
public static final String AUTH_TOKEN = "myAuth";
public static void main(String[] args) {
Twilio.init(ACCOUNT_SID, AUTH_TOKEN);
Message.creator( new PhoneNumber("+myNumber"), new PhoneNumber("+TwilioNumber"), "I am having Java class").create();
}
}
Code with error
package controllers;
import com.twilio.Twilio;
import com.twilio.rest.api.v2010.account.Message;
import com.twilio.type.PhoneNumber;
import javax.faces.bean.ManagedBean;
#ManagedBean
public class PhoneController {
public static final String ACCOUNT_SID = "myAccSid";
public static final String AUTH_TOKEN = "myAuth";
public PhoneController() {
}
public void testSMS(){
Twilio.init(ACCOUNT_SID, AUTH_TOKEN);
Message.creator( new PhoneNumber("+myNumber"), new PhoneNumber("+TwilioNumber"), "I am having OS class")
}
}

I am using Glassfish as my server and IntelliJ just for extra information

Answer 1

Usually NoClassDefFound errors are related to missing libraries at runtime.
In your case, probably in your local setup you have it in your classpath, running your main method successfully.
Now when moving to a JSF environment, you have a server involved, so you have to pay attention in a couple things:
Is the dependency JAR available on a shared folder/classpath on the server?
Is the dependency being package along your WAR or EAR?
So unpack and check you WAR ans check the classpaths to see If your dependency is available, and provide it in the classpath or WAR/EAR.
