Executar .jar

Boas, a minha duvida é simples, como é que eu dentro de um programa java mando o programa executar outro .jar?

Eu pensei no assunto e uma das maneira que me surgio foi na altura que quiser executar o .jar importo o mesmo para o programa actual e executo-o dentro do programa que o chama, no entanto nao sei fazer isso.

Process process = Runtime.getRuntime().exec("java -jar jar_name.jar");

É possível, mas penso que tens que as colocar no classpath. Mas o melhor é leres a documentação:

http://docs.oracle.com/javase/7/docs/api/java/lang/ClassLoader.html

Alternativamente, podes fazer uma pesquisa no Google por ClassLoader e Dynamic Class Loading.
