Can WDHT handle changed DDS at Prouction Environment for
Webfacing

Our company is webfacing user, after deploying webfacing EAR file to ustomers,
sometimes we have to update DDS file for enhencement or customization. If we
only update this DDS object, webfacing application will bomb at that point.  

So, we need a method to send update only to customer, for example, only one
record changed within DDS file.

We found a way from IBM Webfacing document to partially deploy webfacing
project. That is reconverting the changed DDS file, copying JSP and Javascript
for changed record in this DDS file into production envoronment, and replacing
that XML file in DDSGeneratedData.jar with updated xml file. This method has its
limitation. One is that if adding new DDS file, this method will result in
funcion key text not being picked up. Another is that for some DDS file it does
not work at all.

Is there any other way to delivery changes only to customer without recovert
webfacing project ? Does WDHT can solve this ?


Thanks In Advance

I doubt that WDHT would be a magic solution for what you want.  Based on 
your comment about "funcion key text not being picked up" I would
guess 
that you are not updating the mapping file as well.  I think that 
Softlanding has some tooling that will help with incremental deployment 
of Web projects.

Here are some links that I found with Google that may provide some 
clarification.

(1)Webfacing partial deployment: I have 2 times experience when RPG programmers
requested reface new DDS file, I only convert that DDS file and then partially
deployed this to WAS server. I actually copied related JSP and Javascript folder
and the whole DDSGeneratedData.jar to WAS server and restart application. All
function key texts are not picked up. I had to redeploy webfacing application
normally through EAR file.

(2)If create project through WDHT, deploy EAR file to production environment.
When DDS is changed, without reconvert, (webfacing application will bomb at this
point) Does this application still work at that point (changed DDS file)by HATS,
which dynamically transform datastream into web page "on the fly"?

Thanks

(1)  I will guess that this is probably because you have not updated the 
DDS mapping file and there was a new record or something as well.

(2)  WDHT enabled projects (using HSR or HATS) can handle unconverted 
DDS at the member (DSPF) level but it cannot recover from the case where 
the converted DDS does not match the DSPF and causes an error.
