Thank you in "Viju" and "Nair" for your answers.
According to what Nair said I tested of remove "response.setContentType
("application/x-java-serialized-object")" and I had the same error.
Even error when I put "response.setContentType("text/html") as said
Viju.
Any idea ?
Thank you
nb : The error is :
"java.io.StreamCorruptedException: InputStream does not contain a
serialized object"
