Commons lang problems

Question

Hi there!
Sorry if I post this in the wrong section. But I was unsure of which to choose so I took the most general.
To my problem. I want to use commons lang (http://commons.apache.org/lang/) but I cant make it work. I made a simple testclass to show you the problem:
import org.apache.commons.lang.builder.ToStringBuilder;
public class Person
  private String name;
  private int age;
  public Person(String name, int age)
    this.name = name;
    this.age = age;
  public String getName()
    return name;
  public void setName(String newName)
    this.name = newName;
  public int getAge()
    return age;
  public void setAge(int newAge)
    this.age = newAge;
  public String toString()
    return new ToStringBuilder(this)
      .append("name", name)
      .append("age", age)
      .toString();
  public static void main(String[] args)
    Person p = new Person("Peter", 23);
    System.out.println(p);
}And this is the output from when I run it:
*$ javac -classpath /usr/share/java/commons-lang.jar Person.java && java Person*
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/lang/builder/ToStringBuilder
     at Person.toString(Person.java:36)
     at java.lang.String.valueOf(String.java:2615)
     at java.io.PrintStream.print(PrintStream.java:616)
     at java.io.PrintStream.println(PrintStream.java:753)
     at Person.main(Person.java:45)

Answer 1

*$ javac -classpath /usr/share/java/commons-lang.jar Person.java && java -classpath /usr/share/java/commons-lang.jar Person*
Exception in thread "main" java.lang.NoClassDefFoundError: PersonI have also tried with:
CLASSPATH="/usr/share/java/commons-lang.jar" javac Person.java && java Person
