Hi,  
I am using ruby to check some memcache keys.  
the memcache values are serialized java objects.

Is it possible to read these objects in ruby and output their values?

thanks,  
ad.

Haven’t tried it but a google search on “deserialize java object with  
ruby”  
led to this via the second link:  
[http://raa.ruby-lang.org/project/javaobs/](http://raa.ruby-lang.org/project/javaobs/)

Yes, it’s old and apparently abandoned, but might give you a start 🙂

I guess jruby would be one option. You should be able to use the Java  
Serialization classes directly.
