user-1: I think most would say that anger and prejudice are the main obstacles to compassion, but I'm wondering on the topic of sympathetic joy. If everything is empty, and suffering, and impermanent, how can we be happy for the joys of others which are empty, and ultimately suffering? I feel like being happy for a joy which is in fact suffering is like being glad someone took poison. I would like to develop compassion for other's joys--the real joys that will further their lives--but I find most of the things people are satisfied by detrimental things. Any thoughts?
EDIT: Also, I wonder how, since everything is intrinsically empty, one can truly be happy for events occurring to someone else since they have no absolute effects. This would imply one would have to be happy for the happy emotions others have in themselves rather than what occurs, but once again, but Buddha explained these as suffering, even the most blissful states. 

user362: With practice, you can be content by reflecting on the good karma of others rather than joy or happiness. It is very close, if not the same, to praise. For example, if someone you're showing compassion to is now able to feel happy, then you can think "Now this person has the opportunity to practice dhamma since his problems are lesser. This is good". Maybe you can go further and help the person practice dhamma even for a second. This way, you don't cultivate thoughts that nurture attachment, nor do you appreciate any wrong joy or happiness in the other person you helped (such as thanha).

user8238: First of all you are veering dangerously to nihilism (annihilism). Seeing things as empty impermanent, not self and suffering is to allow us to detached ourselves to pleasures (including the pleasures of the bliss of Jhana). It doesn't mean that everything is meaningless or there are no consequences to our actions.
Emptiness in particularly used by Mahayana to mean that things are ultimately dependent originated. Things happen due to causes and conditions. It does not mean that it's all meaningless and does not matter. This is use to break your attachments to things you cling to as permanent. We should definitely not take this to mean that all actions are meaningless. If we do so we would quickly enter a deluded mindset.
Secondly Mutida or sympathetic joy is the antidote to jealousy and judgement. When we see someone who is better off than we are, we have a tendency to become jealous. Especially we have judged that person as being unworthy of happiness. On the other hand, if we feel they are worse off than we are, we might start to develop conceit, or even pity, and we become unable to rejoice in their good fortune. You can be happy for the limited happiness that they may have, whatever it maybe.
I want to further add that there is one powerful use of sympathetic joy, the joy of rejoicing in the merits of others, that is in their goodness. When we see others doing good things or making progress in the path, it is worth rejoicing, and in fact further aid and reinforce your own cultivation. Commonly you will see Buddhists exclaim 'Sadhu!' - meaning good or well said after seeing good deeds.
