Code directories
I'm brand new to Wicket - trying to see if I can re-design some web
applications to use this framework. A couple of questions have come up
right at the beginning - I'll start with the simple one....
1) Code layout - In my existing system, I have code separated into a
number of different packages - for example,
com.foo.dm (data model)
com.foo.da (data access)
com.foo.servlet
com.foo.util
etc. etc.
Somewhere in the Wicket website, I saw something that said the code had
to be all in one package. But does that mean pairs of java/html files
have to be together, or does the entire program have to be in one package?
thanks,
nbc

It was probably meaning that the Java/HTML pairs should be kept
together[*]. You certainly don't need to keep your program in one
package!
Places to check for info are the main Wicket site, the wicket-examples
linked from there (especially the sources), plus the Wiki. See the
Documentation Index and the Reference Library pages to start!

This worked - but only after running mvn install:installfile ... to
actually load the jar file into the system.
Thanks very much!

Try
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.0.5</version>
</dependency>
in the pom file and see what happens? Maybe it'll download it
automagically when the projects refreshed/reloaded/built...

See http://mvnrepository.com/artifact/mysql/mysql-connector-java for
how to find the pom fragment.

Adding a jar file...
Posted by "Neil B. Cohen" <nc...@verisign.com>.
This question may be as much for Netbeans 6 as for Wicket, but in either
case, I'm stumped...
I want to add the MySQL jdbc driver to my program so I can connect to a
MySQL database. In a regular
VWP project in Netbeans 5.5 I would just add the jar file under the
libraries tab. But it doesn't want to let me do that in Netbeans 6. And
I don't see how to do it manually in Wicket - how would I identify the
driver, and where would I place it so it will be added to the program? I
assume it goes somewhere in the pom.xml file, but I'm not sure where to
put the actual jar file itself...
I put a similar question to the Netbeans forum last night, but have not
heard anything yet. If there is a way to add it manually, that would be
great - at least I can keep working on it....
thanks,
nbc

If you want to do that sure, but that is not typical. The only thing
that should be together are the wicket related parts, but they can be
stored in different packages:
com.example.gui.admin
com.example.gui.users
com.example.gui.products
com.example.gui.products.cheese
com.example.gui.products.wine
com.example.gui.products.footballs
Your domain classes can reside wherever you want:
com.example.domain.cheese.french
com.example.domain.cheese.dutch
They can even come from other JAR files, as long as they are on the classpath.
The only "requirement" for wicket out-of-the-box is to find the markup
files for pages and panels next to the class files of your java files.
The easiest way to achieve this is to put the html and java files *for
your pages* in the same package. That's all.

That makes sense - but if I have data model objects like 'User.java'
which are used by multiple pages, then it would seem that all the pages
(and all the related data model objects) have to end up in the same
package with 'User' - yes? Or am I missing something obvious here... It
seems like the entire program will be contained in one package. That
isn't the end of the world for me - I just want to be sure I understand
it...

Yes, unless you don't want it to, but then you have to resort to other
tricks (enough examples regarding that on this list).
The easiest way to start learning wicket, imo, is to keep everything
related to a page, border or panel together in the same package
directory: .java, .html and .properties
> or does the entire program have to be in one package?
No (unless you want to)
