[Webtest] Use Ant version 1.6.2 with Webtest build 649

[Koorosh Vakhshoori]

Hi all,
   Recently I got the latest Webtest, build# 649. I found out after some 
hard work that I need to also upgrade my ANT to version 1.6.2. It seems 
sometime between Webtest build 598 and 649 the version of xercesImpl.jar 
was upgraded to xercesImpl-2.6.2.jar. I was getting the following error:

[testSpec] INFO (com.canoo.webtest.steps.Step) - Exception thrown from this 
class: java.lang.NoSuchMethodError
[testSpec] ERROR (com.canoo.webtest.steps.Step) - Cannot handle unexpected 
exception in step InvokePage at file:../modules/login.xml:5: with 
(save="loginPage", stepId="goto login page", url="Login", stepType="invoke")
[testSpec] java.lang.NoSuchMethodError: 
org.apache.xerces.xni.Augmentations.removeAllItems()V

It turns out that buried in ANT installation there is a version of the same 
xercesImpl.jar file, and ANT uses that and not the one shipped with 
WebTest. Rather than spending additional time trying to figure out how to 
make ANT to use the one from WebTest, I just upgraded my ANT version.

Hope this note, saves others from spending unneeded debugging time.

Take care,
Koorosh
