Some general n00b-questions
Hello,
I have some general TDK questions, I have downloaded the TDK,
installed it, run it and twiddled around with it and everything seems
fine. I read through most of the Velocity/Turbine/Torque and searched the
mailing lists but some questions remained open to me
1. Could someone give me a brief overview of the files in the
newapp conf-directory and explain the precedence of these files and the
ancillary/ and so forth files, which are just templates and which are
actually used?
2. Turbine seems quite singletoneish, if used for J2EE
applications, where would be a logical place to put a handle to a service
location or EBJ remote handle? Or should it just be poked into the
session?
3. What would be the most clean way in Velocity to implement
interfaces with different modes, e.g. view and edit mode. If-else on every
mode and macro as much as possible?
4. Is there OJB support planned for Turbine? If not, is it
difficult to plug on somewhere in the middle of the current object model?
5. Is there a clean way in Velocity to name and fetch from the
request values for multi-row-entities?
Thanks for your time,
Nik

Hi,
For no. 5 I think he means swhre you have amny entities to choose from on
screen. I use a pull tool called entitylist.
e.g.
At top of your.vm file
## Get the collection of existing databases, and
## make the first database selected, if no database
## has already been selected
#set ( $databases = $entitylist.getAllDatabases() )
#if (!$selectedDatabase && ($databases.size()>0) )
#set ( $selectedDatabase = $databases.get(0) )
#end
#set ( $selectedDatabaseId = $selectedDatabase.getRwDatabaseId() )
then in the form
....
<tr>
#rwLabelCell ("Database list")
<td width="$ui.screenWidgetWidth" >
<select name="selectedDatabaseName"
onChange="fireSelectionType(this.form, "database")">
#foreach ($database in $databases)
#if ($database.getRwDatabaseId() == $selectedDatabaseId)
<option selected>$database.getDatabaseName()</option>
#else
<option>$database.getDatabaseName()</option>
#end
#end
</select>
</td>
</tr>
....
Hope it helps

Where? WEB-INF/conf?

Hmm. This may be personal preference. You could do if-else blocks, or
use separate pages. I usually use the latter to keep it clean.

I don't use it, but I hear Torque can work with OJB; you should probably
ask on the Torque user list.
