Re: [atf-dev] java.lang.ClassCastException: org.mozilla.javascript.Nativ

[Robert Goodman <goodmanr@xxxxxxxxxx>]

There has been some changes to JSLint
that are causing problems when running in ATF.  The ATF runtime uses
Rhino as the _javascript_ engine to run JSLint. It could be argued that the
latest version of JSLint is relying on a behavior based on implementation
of certain _javascript_ syntax. It ends up that Rhino has a implemented this
syntax differently and doesn't provide the same behavior. The ATF team
is working on resolving the problem. Manoj it would be helpful if you could
attach your version of JSLint to bug 186156. 

If JSLint is not configured, the ATF
runtime will disable the JSLint validator. The ATF runtime will pop-up
a warning dialog that JSLint is not configured the first time the JSLint
validator tries to run and then disable the JSLint validator. The JSLint
validator looks for a variety of coding structures that are considered
to be bad practice in _javascript_. Checking for illegal _javascript_ syntax
is done by a different validator, so syntax validation is done independently
of whether JSLint is configured. All other functionality of ATF will work
without having JSLint configured. 

The ATF teams long term plans are to
replace JSLint validation with a different implementation, but this isn't
available yet. 

I will post another messaged when the
ATF team has a solution to the problem. 

   Thanks
     Bob

Subject	[atf-dev]         java.lang.ClassCastException: org.mozilla._javascript_.NativeString

Hello all,
 
I’ve followed the instructions on http://www.eclipse.org/atf/downloads/index_build.php?plat=all&buildID=0.2.1-v200704051500&XULPlugin=true
 
I installed eclipse WTP 1.5.2 (fresh install),
then installed ATF (atf-0.2.1-v200704051500.zip).  In Windows | Preferences
| ATF | _javascript_ Validation, I set the “JSLint Location” value to the
location of my jslint.js file.
 
When I save a JSP page (with _javascript_),
I get the a popup with the title “_javascript_ JSLint Validator” and text
“org.mozilla._javascript_.NativeString”.  The trace below appears
in my .metadata/.log file.
 
Does anyone have any ideas on how to fix
this?
 
Thanks,
Manoj
