I didn't have a problem when I used <fmt:setLocale>, but I was experimenting with how <fmt:formatNumber> behaves without using that. It turns out that what I was doing wrong was setting my system's locale to "English (United Kingdom)" but forgetting to set the browser itself to the same locale. Doh!

I'm getting a JspTagException from line 212 of FormatNumberSupport.java. There is no root cause reported, so I can't be more specific. >The tag handler calls java.util.Currency.getInstance() with the >specified currency code. This method throws an >IllegalArgumentException "if <code>currencyCode</code> is not a >supported ISO 4217 code" (quoted from the javadocs). This is what we >mention in the "Constraints" section of <fmt:formatNumber>. We do >not implement any additional constraints on the currency code. ISO 4217 defines both alphabetic and numeric currency codes. There is nothing in the javadoc for java.util.Currency, or elsewhere as far as I can determine, to indicate that only the alphabetic form is supported. However, perhaps this is the case, and that's why I'm getting an exception when I try to use the numeric form? -- Martin Cooper > > > >Jan -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
