Can I cache *any* object? I get exceptions when I attempt to cache
objects I've created, although I can cache simple objects like Strings.
Unfortunately cache.put(String foo, myCustomObject bar) doesn't tell me
much more than the name of the class I'm trying to cache (i.e.
"myCustomObject"). It doesn't tell me why it threw the exception, it
just prints a stacktrace. Like I said - it all works fine if I do this:
cache.put("foo", "bar"), but if I do cache.put("foo", new
myCustomObject()) it will fail. I've even cast myCustomObject back to
Object, but it still doesn't like it. Any way to get more verbose
messages out of the JCS code instead of just ERROR level?
I suspect that at the very least your custom object would need to be serializable before it could be cacheable. Does your object implement the Serializable interface?
I suspect the method signatures in JCS should say they only accept Serializable, rather than Object, though I haven't looked at the code to be sure.
