Where in Java will you be on your birthday?
If you are in West Java how about heading to Cianjur which is about 2 hrs from Bogor by mini bus or 3 hrs from Jakarta.
Check out Yudi Sujana's homestay programme. He is featured in LP South East Asia on a Shoe String and also the new LP Indonesia from Jan 2010.
Here is a little website an English traveller built for Yudi whom I have known since beg Sept 2000.
From Cianjur you can go down to Pangandaran Beach and see Green Canyon etc.
If you happen to be in Central Java then a trip to Dieng Plateau would be nice - a very cool area with temples etc.
Visit Yogjakarta, Boroburdur and Prambanan temples.
In East Java a trek to Gunung Bromo or a trip to Kawah Ijen would be great places to celebrate a birthday.
