ISPN000136: Execution error (faiure to marshall argument)

[dex80526]

Hi all:  I set up a replication cluster with 2 nodes with 5.1CR code, but I got the following exceptions when I add a cache data/entry (below).

My data object is a complex java object. I did not configure any serializer.  Do I have to confgiure a special serializer here?

To replicate data, it needs to be marshalled somehow. You should find all the info you need in https://docs.jboss.org/author/display/ISPN/Plugging+Infinispan+With+User+Defined+Externalizers

From marking your key/value instances as java.io.Serializable or java.io.Externalizable, to taking advantage of your own marshalling layer which performs better.

Galder: thanks for response.

Interestingly, my java object is already marked as "Serializable".  It looks like some child objects are not serializabe.

I'll try the customer externilizer. thanks.

[galder.zamarreno]

Hmmm, what about any other objects that your java object might reference? Try enabling TRACE logging and you should be able to get more info about the offending object.

Galder:  Thanks for looking into this. It is caused by some child objects (contained in a list).

I fixed the problem as you suggested.
