How to store this (key1,key2, Object) ?

[exquisitus]

Is there a data type in the JDK (1.4) that allows me to do this (and
also retieve) or do I have to roll my own?

What about storing (key1 + "<delimiter>" + key2, Object)

No and No.
You could use Apache Commons Collections' MultiKeyMap
<http://jakarta.apache.org/commons/c...ache/commons/collections/map/MultiKeyMap.html>

Thanks Roland. Can I use the MultikeyMap in a session EJB?

Thanks Thomas, this is probably the simplest way to do what I want to do

Yes, if you deploy the jar with the Commons Collections to your J2EE
server and if MultiKeyMap is serializable (let me check... yes it
implements java.io.Serializable) and all keys/items you store in the map
are too, then I wouldn't know a reason why you couldn't.
