Getting error sun.io.MalformedInputException when entering accented characters to HTTPPOST sample from MQ V7 Bridge for HTTP, using Linux

Troubleshooting

Problem

You are using a Linux system and you have installed the WebSphere MQ V7 Bridge for HTTP servlet in an application server. Then you run the HTTPPOST sample using English characters and it works fine. However, when you run it again and try to enter accented characters (áÁ-ñ-ü-¡!-¿?), you get an error:

Symptom

Cause

You are using Java™ 1.4.2 and the locale is: en_US.UTF-8:

$ java -version
java version "1.4.2"

$ locale
LANG=en_US.UTF-8

Resolving The Problem

This section offers a workaround and a permanent solution:

a) Workaround - you can keep Java 1.4.2, but you have to modify the locale as follows:

$ export LANG=en_US
$ locale
LANG=en_US

b) Permanent solution: you need to upgrade your Java from 1.4.2 to a most recent version, such as 1.6.

$ java -classpath . HTTPPOST HTTPTESTQ hostname.x.com:9080 mq
HTTP POST Sample start
Target server is 'hostname.x.com:9080'
Target queue is 'HTTPTESTQ'
Target context-root is 'mq'
áÁ-ñ-ü-¡!-¿?

HTTP POST Sample end
