Everything is right :-).
<jsp:setProperty name="test" property="age" param="p_age"/>
It means that your bean has a method "setAge(String p_age)". Attribute must
be a String type and you would use the next code:
public void setAge(String p_age)
{
try {
age = Integer.parseInt(p_age);
}catch (Exception e){ }
}
