Hello All, I work on real-time financial trading systems written in Java/Swing/Sybase (and some other technologies). However, I am quite inexperienced with web technologies such as JavaScript, Ajax, json, servlets etc. Please go easy on me ;-)
I'd like to create a web front-end on one of these systems. After a bit of research on stuff like ExtJS/Sencha (not sure of the licensing), jQuery seems to be to "low-level" for me right now and a few others - I've decided to invest time in learning qooxdoo. Over the last 2 days, in between watching the footie (c'mon, England!), I've managed to: - go through all the qooxdoo demos - v. nice and fully-featured. (Well done, guys!). - downloaded and ran the HelloWorld custom app - my first ever foray into javascripting. - modified the HelloWorld app to use RPC to talk to the RpcServlet running on Tomcat. Not sure how current RpcJava qooxdoo-contrib is as I initially couldn't get this work at all. But after putting in loads of debug stmts I found that RpcServlet.getServiceInstance() method uses the MethodUtils.getMatchingAccessibleMethod() which for some reason never returns. I fixed it locally by using the MethodUtils.getAccessibleMethod() instead - my first ever bit of rpc-json'ing :-) So the end architecture I hope to have is:- - qooxdoo web frontend GUI calling the.... - RpcServlet or my own variant running in Tomcat (via Apache web server) using an... - in-house application server providing accessing to services etc etc. It also supports a simple login() and permissions() services for authentication and authorisation. Next on my list to find out about is:- 1. How do I do async updates back to the qx client? Or do I have to implement up a client driven polling mechanism? 2. The trading system is quite complex (ie 30+ screens). I guess this could mean a huge production javascript file. What are the options/tradeoffs in partitioning a GUI into bitesized bits? 3. Client Login/Authorisation : Will just use the servlet session. I feel confident about 3. but if anyone has any views on 1 and 2, then I'd be most grateful. In the meantime, I'll try all the other tutorials.
