Re: [flexcoders] Actionscript on JSR223
A hack would be to use the GWT code and Flash's ExternalInterface to validate via the Javascript produced by GWT and loaded in the browser. I don't know how much you have to commit to GWT before you can use it though; haven't used it before. 2009/7/10 Sam Lai : > Doesn't GWT do something similar, converting the necessary Java code > to Javascript?

Re: [flexcoders] Actionscript on JSR223
Doesn't GWT do something similar, converting the necessary Java code to Javascript? Maybe that part can be reused as AS code. Granted, you will lose the typing in the validation code, but I would presume that GWT would've thought about that and mitigated the security issues there? P.S. Silverlight can do this, for obvious reasons. 2009/7/9 Tom Chiverton : > > > On Wednesday 08 Jul 2009, Tim Rowe wrote: >> Does anyone happen to know of any JSR223 (Java platform scripting) >> implementation(s) of ActionScript for dynamic use?

Isn't that a good idea ? In theory anyone could write a replacement front-end and call your services, so you should validate the business rules there. At the same time, you don't want to round-trip to provide feedback to the user, so the rules have to be in the front end too. I would argue the front end rules would be more relaxed, and probably not aware of the full security context, however. -- Helping to assertively cultivate high-end wireless intuitive models as part of the IT team of the year, '09 and '08 This email is sent for and on behalf of Halliwells LLP.

[flexcoders] Actionscript on JSR223
Does anyone happen to know of any JSR223 (Java platform scripting) implementation(s) of ActionScript for dynamic use? I'm currently looking through a lot of our business data validation logic which is implemented in two places arguably unnecessarily - both on the front-end in AS and then again on the back-end in Java. The scripting.dev.java.net project page still seems to be absent of any AS interpreters. It would seem far more logical to be able to just implement this once in a single language. Two options I can see are using a Java->AS convertor, or to write this all in AS and validate the data again on the back-end against the same code. The latter would be preferable, mostly due to the stigma around here about generated code. Though much of this code might work as javascript if we dropped the typing on data, that's far from an ideal solution. Any project suggestions here would be appreciated.
