ActiveRecord has proven to be a easy to learn and productive ORM solution, you can define your application model with few lines of code, the syntax is much more concise than any other ORM solution.
But, in other hand, rails doesn’t have a elegant way to work with views, with a lot of loops and conditional expressions in the middle of code, this kind of approach remembers me the PHP coding 8 years ago, where after several lines your code become very hard to understand an maintain.

I have been working with regular expressions in Java, regular expressions are very useful to retrieve some data based on document structure. In my example I’m extracting cellular model and brand based on particular html document structure, take a look on html code below:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 | <html> <head> <title>Regular expressions sample data </title></head> <body> <font style="font-size: 8pt;" face="Verdana"><br /> </font><font face="Verdana" size="1"><b>Audiovox:<br /> </b></font> <a href="http://cellular.com/audiovox9500.shtml"> <font size="1">CDM 9500</font></a><font size="1"> | </font> <a href="http://cellular.com/thera.shtml"> <font size="1">PDA - (Thera)</font></a><font size="1"> | <a href="http://cellular.com/audiovoxppc6600.shtml"> PDA - PPC6600 (Harrier)</a>.<br /> <br /> </font> <font style="font-weight: 700;" face="Verdana" size="1">Cyberbank:<br /> </font> <a href="http://cellular.com/cyberbankpoz.shtml"> <font size="1">CB 0870 BR (PoZ)</font></a><font size="1"> | </font> <a href="http://cellular.com/cyberbank_cb880.shtml"> <font size="1">CB 0880 BR (Triton)</font></a><font size="1"> | <a href="http://cellular.com/cyberbank_x315.shtml"> CP X315 BR (PoZ EVDO)</a>.<br /> <br /> </font><b><font face="Verdana" size="1">Compaq:<br /> </font></b><font size="1"> <a href="http://cellular.com/compaq_ipac3700.shtml"> IPAC-3700</a>.<br /> <br /> </font></body> </html> |
Alguns dias atrás eu estive realizando pequenos testes com o Wicket, ele tem uma idéia semelhante ao Swing, é realmente um framework OO com um pouco de HTML e muitas classes Java, creio que quanto à modelagem é muito mais fácil trabalhar com o Wicket do que com o JSF.
Porém quando você que ter flexibilidade em aplicar modificações no markup como o JSF oferece as coisas mudam pois para cada página HTML existe uma classe Java e somente via código Java é possível adicionar componentes coisa que no JSF pode ser facilmente feito.
Creio que em breve farei um artigo comparando ambos.
