How to properly set up jaxrs client dependencies?

I'm trying to use jax-rs 2.0 for an existing java client code (java 8), it didn't previously support maven (and i do not wanted to use maven or any similar frameworks) but the jax-rs "client" needed a dependency for org.glassfish.jersy.client, so i went out and read about dependencies in general and frameworks which i'm new to.
added maven framework to my project, and edited the pom.xml file for dependencies :
<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">
<modelVersion>4.0.0</modelVersion>
<groupId>groupId</groupId>
<artifactId>CVT Sale Data Manager</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>org.glassfish.jersy.bundles</groupId>
<artifactId>jaxrs-ri</artifactId>
</dependency>
<dependency>
<groupId>org.glassfish.jersy.media</groupId>
<artifactId>jersy-media-moxy</artifactId>
</dependency>
</dependencies>
</project>
and this is part of the restapi code:
package api;
import javax.ws.rs.client.*;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.core.Response;
public class RestApi {
private static Client client;
private static WebTarget baseTarget; //base url
public RestApi()
{
//changed on the server
ClientBuilder.newBuilder().build();
client = ClientBuilder.newClient();
baseTarget = client.target("http://127.0.0.1:8000/api");
client = ClientBuilder.newClient();
}
somehow i'm still getting the same error:

Exception running application Launcher
I'm very new to these dependencies type of thing so its very much possible that i have a very obvious error that i do not know about, i apologize in advance if that is the case.

I got java.lang.NoClassDefFoundError when trying to automate a forum using POM in Selenium... how can I fix this?

I'm trying to use POM for a web page I'm trying to automate and I got the following error:

I'm not sure what's going on. I added TestNG as well as any jar files to Selenium. Anyway, here's the code:
The first one is from a file I named Forumloginapplication.java in a package known as testcases
package testcases;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.Test;
import objectrepository.SimpleProgrammerForum;
public class Forumloginapplication {
#Test
public void Login() {
System.setProperty("webdriver.chrome.driver", "C:\\Users\\Adam\\Downloads\\chromedriver.exe");
WebDriver driver=new ChromeDriver();
driver.get("https://simpleprogrammer.com/members/");
SimpleProgrammerForum sp=new SimpleProgrammerForum(driver);
sp.Loginnav().click();
sp.Userid().sendKeys("10asmock");
sp.Userpass().sendKeys("secret");
sp.Rememberme().click();
sp.Login_button().click();
}
}
This one is named SimpleProgrammerForum.java in a package known as objectrepository:
package objectrepository;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
public class SimpleProgrammerForum {
WebDriver driver;
public SimpleProgrammerForum(WebDriver driver) {
this.driver = driver;
}
By login_navbar=By.xpath("//span[#class='p-navgroup-linkText'][contains(text(),'Log in')]");
By username=By.name("login");
By password=By.name("password");
By login_checkbox=By.name("remember");
By login_button=By.className("button-text");
public WebElement Loginnav() {
return driver.findElement(login_navbar);
}
public WebElement Userid() {
return driver.findElement(username);
}
public WebElement Userpass() {
return driver.findElement(password);
}
public WebElement Rememberme() {
return driver.findElement(login_checkbox);
}
public WebElement Login_button() {
return driver.findElement(login_button);
}
}
Another thing I get when I run the program is a popup which tells me: "Error: A JNI error has occurred, please check your installation and try again." followed by another popup which states: "A Java Exception has occurred."

TestNG has a JCommander dependency:
<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"

...
<dependencies>
<dependency>
<groupId>com.beust</groupId>

</dependency>
...

</project>
You will need to use Maven or add all TestNG dependencies manually as jar files.

I have faced the same problem.
I made some changes in my pom.xml. Ff you are using the dependency of javax mail as well aws sdk then make sure that javax mail should be declare before the aws sdk's.
If you change the sequence then it will show the above error as it's loading jars in wrong sequence.As this worked in mine case, Hope this will work for you!

Problem solved. After I install Windows10, it broke my access to folders when I have save the external jars of frameworks.

Throwing Error Running slf4j-api through Maven

Should set the classpath manually for slf4j jar file??

Maven picks up the dependencies you defined in the pom.xml from your local repository so everything compiles fine. However when you launch the application from a script or commandline you need to specify where the necessary classes are found, through the classpath.
For eclipse, there's the m2e & m2e-wtp plugins which integrate maven with your IDE so you don't need to add the jars manually one by one. Instead you'll have a sort of "virtual maven library" which contains references to all your dependencies, like in the image below:

Cannot find the main class after converting java project to maven

I have a very simple HelloWorld code in Java which works ok. I'm using Eclipse and trying to figure out how to import dependencies for a project with the maven2 eclipse plugin.
public class testMavenDep {
public static void main(String arg[]){
System.out.println("Hello World");
}
}
However, when I right click on the project > configure > convert to maven project, and then try and run it gives me an error message saying...
Could not find the main class: testMavenDep.testMavenDep. Program will exit.
And the following in the console...
java.lang.NoClassDefFoundError: testMavenDep/testMavenDep

My question is, for an already existing Java Project, what is the proper way to add maven dependencies? I can add the dependencies using the above method but I'm getting issues with it losing track of the main class. Thanks in advance!

What is the source folder that you are putting your main class in? By default, Eclipse puts it in src, but maven conventions are src/main/java. It could be that adding maven dependencies is changing your source folders so that your class is not compiled.
