Bytes getting misinterpreted..

Hi,

I have a situation wherin I am firing MQ requests to a backend system to get some data. The data is a string on the backend system 'Credit 1 [1000] '.
The MQ server uses character encoding ISO-8859-1.

However, when this data is read by a Websphere 5 environment, I get 'Credit 1 �1000! ' back.
The same when read by a Websphere 6 environment gives me 'Credit 1 000! '.

How do i resolve this? I have tried setting the 'client.encoding.override' to ISO-8859-1 / UTF-8 in the Websphere server.. But no success!!!

This isn't a minor difference between ISO-8859-1 and UTF-8; in fact ISO-8859-1 is a subset of UTF-8 in the sense that they both encode characters in the same way if they encode them at all.

The changes to [ and ] suggest to me that there is some kind of EBCDIC-based encoding going on somewhere. Those are basic ASCII characters so the only thing that could change them like that is something completely different from ASCII.

Read using what code?

Do you have any way to dump the binary values of the characters in the backend system string?

Paul & William.. Many thanks for the response.
I have java code deployed in Websphere 5 & 6 servers that fires a MQ message to get the data from the backend. I get a byte[] back & I convert the same to a string & then parse it for information.
Do you reckon it is something to do with the character sets used in the JVM of the servers?
If yes, how do I change the character set used?

Thanks.

Sounds like a WebSphere question. I'll move this to the WebSphere forum, you might get more responses there.

**************
'client.encoding.override' to ISO-8859-1 / UTF-8
**************

After setting the above, it should work... I am surprise.....

Did you restarted the server after making above changes to the JVM? If not, pl. do so and see how that affects...

Cheers,
