ECB currency rates taglib ver. 1.3

    Custom JSP taglib lets you request currency rates from ECB. The reference rates are based on the regular daily concentration procedure between central banks within and outside the European System of Central Banks, which normally takes place at 2.15 p.m. ECB time (CET). For example:
 


<%@ taglib uri="taglib.tld" prefix="r" %>

<r:GetECBRates result="A"/>

You car request historical rates (for the last 90 days). The attribute date sets date in format yyyy-mm-dd:
 


<%@ taglib uri="taglib.tld" prefix="r" %>

<r:GetECBRates date="2014-06-25" result="A"/>

Tag GetECBRates creates a page scope variable with results. And now you can examine your results:
 



Time is <r:GetECBRatesTime result="A"/>
RUB:<r:GetECBRate result="A" currency="RUB"/>
USD:<r:GetECBRate result="A" currency="USD" id="B"/> <%=B%>

and you will get some like this:

Time is 2006-01-10 RUB:34.3800 USD:1.2064

Tag ForEachRate lets you iterate over returned data:
 


<r:ForEachRate result="A" id="var">
 <br><%=var.getCurrency()%> : <%=var.getRate()%>
</r:ForEachRate>

The nested page scope variable described by the attribute id lets you request the following properties:

String getCurrency() - returns a name
double getRate() - returns a rate.

So you will get some like this:

BGN : 1.9559
LTL : 3.4528
GBP : 0.6833
ISK : 73.92
PHP : 63.523
EEK : 15.6466
CHF : 1.5437
CZK : 28.8
USD : 1.2064
etc.
