I know a solution for RichFaces, I'm pretty sure it will works for PrimeFaces as components are almost the same :

EDIT : Here is the translation applied to your code :

And for the bean :

@ManagedBean(name = "beanInscripcion") @RequestScoped public class BeanInscripcion implements Serializable {

static String strURL;
private List estados; 
private List municipios;
private int id_estado;
public BeanInscripcion() throws SQLException{
        estados = new ArrayList();
        buscarEstados();
}

public void buscarEstados() throws SQLException {
    Connection connection = getConnection();
    Statement statement = connection.createStatement();
    ResultSet result = statement.executeQuery("SELECT * FROM estado");
    result.beforeFirst();
    while (result.next()) {
        Estado estado = new Estado();
        estado.setId_estado(result.getInt("id_estado"));
        estado.setNombre_estado(result.getString("nombre_estado"));
        estados.add(estado);
    }
}

public void buscarMunicipios() throws SQLException {
    Connection connection = getConnection();
    Statement statement = connection.createStatement();
    ResultSet result = statement.executeQuery("SELECT id_municipio, nombre_municipio FROM municipio WHERE Estado_id_estado = '" + id_estado + "'");
    result.beforeFirst();
    while (result.next()) {
        Municipio municipio = new Municipio();
        municipio.setId_municipio(result.getInt("id_municipio"));
        municipio.setNombre_municipio(result.getString("nombre_municipio"));
        municipios.add(municipio);
    }
}

public Connection getConnection() {
    try {
        strURL = "jdbc:mysql://localhost:3306/mydb";
        Class.forName("com.mysql.jdbc.Driver");
        return DriverManager.getConnection(strURL, "root", "root");
    } catch (SQLException ex) {
        return null;
    } catch (ClassNotFoundException ex) {
        return null;
    }
}

public List getEstados() {
    return estados;
}

public void setEstados(List estados) {
    this.estados = estados;
}

public List getMunicipios() {
    return municipios;
}

public void setMunicipios(List municipios) {
    this.municipios = municipios;
}

public int getId_estado() {
    return id_estado;
}

public void setId_estado(int id_estado) {
    this.id_estado = id_estado;
}

}

Hope it will work since it is not tested!
