Subject I18N and number formatting
Date Fri, 18 Apr 2008 18:26:28 GMT
I wanted to format parameters of message. I did as follow
in my jsp  I wrote:
<fmt:message key="something">
<fmt:param value="${123456}" />
</fmt:message>
 and in the properties file :
...
something= hi {0,number,integer}
...
Then I get IllegalArgumentException. I think fmt:param tag sends my
parameter as String to DecimalFormat.format() and had not tried to
cast it to integer before passing it to DecimalFormat.format() method.
The exception stack trace  in tomcat5.5 :
2008-04-17 10:34:37,292 ERROR
