Some beginner's EPL questions

Question

In the fx example,
(a) Where, or rather, how is lastPrice defined? It seems that preprocessors.xml file is the only places which uses it, but I don't seem to find out how it is defined in the project. Note it is used in
<rule id="UsdToEurRule"><![CDATA[
      insert into ForeignExchangeEvent     
      select avg(lastPrice) as price, 'USD' as fromRate, 'EUR' as toRate
      from (select * from StockTick where symbol='USDEUR') retain 1 sec
      where lastPrice < 3.0 and lastPrice > 0.25
      ]]>
</rule>
(b) Where is StockTick defined? Is the src code for com.bea.wlevs.adapter.packet.impl.marketsim.TestMain available? How does one relate StockTick to the TestMain class? Can someone give me an example of how an event for, say, the fxMarketAmer look like? And can workshop be used to look at the events in the stream (not just in the user code)?
Thanks in advance.

Answer 1

I developed an aplication for CDC+FP using JCreator and j2se 1.4 in Windows, of course, as you said, respecting the classes of CDC+FP. I don't know if it's the best way to do it, but it worked fine in a Zaurus and in a iPAQ with Jeode.
