Hi,
thanks for the answer.
The deserialization code is like this :
final byte[] byteData = Base64.decodeBase64(dataStr);
ByteArrayInputStream bout = null;
ObjectInputStream oos = null;
try {
bout = new ByteArrayInputStream(byteData);
oos = new ObjectInputStream(bout);
toReturn = oos.readObject();
} catch( ...) {
} finally {
}
With the ObjectInputStream there is no class loader parameters but some
resolver (i will check this way).
For the second case, do you have an example of "class context injection" ?
Regards
Hervé
