|Subject: [jBoss-Dev] CMP and Hashtable?!? Is it possible?!?
|
|
|hello list,
|
|i'm new on the list and think i've found a bug
|(correct me if i'm wrong).
|
|I've an entity bean with two CMP-fields.
|The first field is a string and the pk.
|The second field is a Hashtable.
|
|And now I can deploy the entity bean. All works fine
|until the client tries to create a new instance.
|
|The client will become the reference for the home-
|interface, but home.create(String pk) throws following
|exceptions. I've thought all serializable objects can be
|a cmp-field.
|
|thx in advance for help,
|
|Ralf
|
|P.S.: Tested versions are jBoss 2.0 and the daily snapshot from February,
|8th
