Problems returning a string

[Nic Hobbs <ni...@subdimension.com>]

Hi guys,

I have a problem returning a string from a service as described below and
wondered if anyone could help.

I basically have a string which is base64 encoded and when I print it out in
java it looks something like
:JQAAABgAAABjY9wni2+tRzUsUHZRrI75sF6K96D0gwjIugsuu7F1ZQ==:
(bounded by : for clarity).

Looking at the bytes that compose this I see the last two bytes are the two
'=' signs. However, when I view it in the tcpmon supplied with axis the
string shows two little boxes on the end before the last colon and I get an
error in my application:

org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x0) was
found in the element content of the document.

I have tried setting the retuen class and the return type to be strings but
to no avail.

Does anyone have any ideas?

Many thanks,
