SerializationException while sending Flex->ByteArray to Java->byte[]

[Karandes]

Hi,
I am getting an error: "Creation validation for class '[B' failed."
At the time of sending data through remoting from flex to java.

We have a Dto on flex side which contains property "public var logo:ByteArray;",
And the corresponding java side property for the Dto is "public byte[] logo;".

While transferring this dto from flex to java, blazeDS fails and below log is displayed on the blazeDS side.

Any pointers to the cause and the solution will be a great help.

Thanks in advance.

Didn't found the Reason of the problem!
So instead of "ByteArray" used plain "String" and converted byteArray to sting using Base64Encoder.encodeBytes();

Hope this will help some one!
