not sure what you mean be "importing by double clicking". Do you
mean that Excel should open automatically when receiving the
file from the server? I think you need to set the correct
content-type in the response to let this happen.

There are no japanese characters in Cp-1252, so this will
never work.

The viewer tries to make sense of the binary data, you surely
have seen the effect of UTF-8 data being shown "as is". This
is a similar effect.

getBytes without a parameter uses the system-charset which
might not be the one you expect for the encoding. This can
coincidantly work on a Linux-system but on a Windows-system
you get corrupted data.

Both lead to the same Java Charset.
