How can we make Laszlo-Java integration easier

Hi,
I've been a Laszlo user for more than 3 years and, as you maybe know, I manage the Italian community. In my development experience I always missed a powerful tool to integrate OL apps with Java back-ends. This need made me create my own tool that I published as a googlecode project. You can see it as an alternative to OL java-rpc, but I think it can be also seen as a start line to make OL users' life easier. My question is: which features should such a tool provide to be really useful and can it be a good way to make OL adoption wider? This is my way to contribute to OL according to Tucker's manifesto.

yes usage of annotation is really smart. You might can extend that similar to GSons annotations, to hide or set attribute names for the Java-Objects when you transfer them to the client. That way you can change server side code without interfacing the client and can reduce/finetune the data that is send between client and server.

This is very cool!
I've been wanting to update the laszlo-rails client code for a while now to keep a dataset in sync with a server-side model automatically. When the dataset value is changed, the corresponding object on the server should be automatically updated. Paging for large datasets was also supported. Both of these are very useful for tabular data, but they currently require XML data - because datasets do. JSON isn't as useful in many cases because there's no way to do replication and receive change events in Laszlo - but it's certainly lighter-weight, and partially solves the typing problem that XML data requires a schema for... In any case, the client/server protocol should use XML or JSON so it can be implemented for other server-side languages.

I'm really interested in JSON support, but I have to say eu4ria gives its best with Laszlo replication.
I wonder if JSON datasets could be a valuable investment in future. Regards, Quirino

It seems that JSON is becoming pretty language-independent (http://json.org/
). So maybe XML is less important. Also, EcmaScript 5 will have native JSON import/export which is quite powerful.

We've also had some discussions about possible APIs for a next generation of components which might use javascript and JSON datastructures rather than XML
