Re: T5 newbie books/tutorials and a couple of questions?
Kevin,
I, too, would recommend using a new entity to resolve the many-to-many
into a pair of one-to-many relationships. But please don't ask me to
justify that statement - I came to the conclusion too long ago to
remember the reasons. All I remember is that it's less pain in the
long run (and you'll keep more of your hair).
grep JumpStart for many-to-many and you'll find the UserRole example.
Regards,
Geoff

Make sure you really need ManyToMany with Hibernate. Often, two
OneToMany
relationships will suffice.
Take your time with Hibernate. See how the different options result
in
different implementations (in the database) of relationships. Reverse
engineer an existing database and see what Hibernate gives you. I
think I
know Hibernate pretty well, and yet I keep the reference guide up
whenever
I'm working with it - even with content-assist. Oh, and take some
time to
figure out how you are going to implement equals() and hashCode() -
those
are important questions with Hibernate.
Have fun!

Re: T5 newbie books/tutorials and a couple of questions?
Kevin,
I'm a believer in Samson and Delilah. Cutting your hair is making you
weak! As a chess player, I never play chess the week after I get a
haircut, as I just loose. Also, Garry Kasparov, former world champion,
used to say that the brain worked better if it was 1 degree warmer than
the rest of the body. So if you must shave your head, at least wear a
woolly hat. Thinking caps are also good!
Ciao,

T5 newbie books/tutorials and a couple of questions?
Tapestry Fans, I've been tinkering with Tapestry a little bit off and on but am still pretty much a complete newbie. In the past I've tried a few other Java frameworks, but a framework that requires more lines of XML configuration than lines of source code never made any sense to me. I've also tinkered a bit with various script based frameworks like Ruby on Rails and Django. At the moment I have two websites I act as webmaster for. My personal web site is currently a mixture of PHP and PSP(Pascal Server Pages). Actually I think PSP is now known as PWU - Pascal Web Units. The second is a local canine agility group's web site which is currently Django based. I'm considering converting both to Tapestry. In the past I purchased the PDF version of Enjoying Web Development with Tapestry and went through part of it with Tapestry 4. That was quite a while back and don't really remember any of it, which is probably a good thing considering how different Tapestry 5 is. I've gone through the Tapestry 5 tutorial a few times and was thrilled to recently discover it now has some database examples. The last page of the tutorial says: ... but Tapestry and this tutorial are a work in progress, so stay patient, and check out the other Tapestry tutorials and resources available on the Tapestry 5 home page. I checked the Tapestry 5 home page but couldn't find any other tutorials. I'm anxiously awaiting other tutorials and/or additional sections of the current tutorial. I purchased Tapestry 5: Building Web Applications: A step-by-step guide to Java Web development with the developer-friendly Apache Tapestry framework when I first heard about it but was underwhelmed, especially with it's lack of database examples. Now that the tutorial has got me going with some database examples, I'm taking another look at that book. Will all the examples in the book work with the current version of Tapestry 5 or are there any changes I should be aware of? Are there any other Tapestry 5 books available now or in the near future? Where can I find some relational database examples? I think I came across a couple of entity examples with annotations along the line of @ManyToMany, @OneToMany, etc., in the documentation section of the Tapestry web site but I'm now having trouble finding them again. Can the grid component handle hierarchical data? For example, the brags page on WAG's website currently looks something like: http://www.WacoAgilityGroup.org/WAG/Brags/ which is pulling data from three different tables. The Members page currently looks like: http://www.WacoAgilityGroup.org/WAG/Members/ It's currently a static page but I'm planning to move everything into the database, which will also involve a few tables. If the grid component can handle hierarchical data, can someone point me towards some examples?

RE: T5 newbie books/tutorials and a couple of questions?
Search the list for the Jumpstart application. It has been kept right up to date with the latest release of T5. I think you will find it has many good examples. (Also, search the Wiki for titles with Tapestry5. It's not all up to date, but there's some great stuff.) I'm not sure you really want a grid for what you have displayed, but rather Loops generating the tables on your own. Because you have both column and row groupings (COLSPAN,ROWSPAN) on the pages you listed, I'm not sure how you would do things like apply sorting. You could override the cell contents to come up with some really custom stuff, and you can even put grids within cells of other grids. The annotations you mention (like @OneToMany) are part of Hibernate Annotations, and there is a tapestry-hibernate module for easy integration of Hibernate. I do my Hibernate integration with Spring (and tapestry-spring), but it will make life simpler if you can do it with tapestry-hibernate. In the end, it doesn't really matter to Tapestry how you construct your object graph. Hibernate has a learning curve all its own, so if you're not familiar with it, take some time to learn it on its own. At least be prepared for some hair-pulling if you try to learn both Tapestry and Hibernate at the same time.
