A Java Question...
I have a db Table consisting of 10 (say col_A, col_B, col_C, col_D, ...
col_J) columns. After accessing these data using a PullTool (as suggested
by Scott and Peter), I stored them in a Vector/List. Before I display them
in my .vm file, I want to perform some filtering, e.g. select col_A =
"some_Text".
The question is:
I can extract what is in the Vector as Objects which has all ten columns
in it, it returns a certain address. But How do I get data in col_A out
and perform the filtering I intended to do?
best wishes

Re: Howto create a VECTOR for Velocity
Posted by Eigen Technology Pty Ltd <mi...@eigentechnology.com>.
Say I pulled some data from a database:
ID Col_2 Col_3
1 A 10
2 B 20
3 C 50
4 D 100
5 E 0.5
I then perfomed some arithmatic manipulation, e.g. invert all the number
in Col_2, and now my new data are:
ID Col_2 Col_3
1 A 0.1
2 B 0.05
3 C 0.02
4 D 0.01
5 E 20
I now want to pass these data to Velocity, I have to encapsulate them in a
Vector first. How do I do that?
If I have a Vector TEST,
TEST.addElement(??)
will only work for single col arrays. My case need to have the data put
into some form of Objects and then create the Vector ... which is what I
am asking for... thanks

hum, not sure what you mean by "this vector is not from Turbine". You
can get the contents of your vector from Turbine, directly from a
database, or anywhere else. Can you give me more infos?

The only thing that I can see, and that's probably more to do with your
example, is that you use "entry" twice.
Do you have logs/stacktraces we could look at?

Why can the processing not occur before you put the list/array into the
context? This would be the MVC thing to do and would simplify things
greatly.

Re: Howto create a VECTOR for Velocity
Posted by Eigen Technology Pty Ltd <mi...@eigentechnology.com>.
Well, the reason I raised the question was because I tried and failed
using arrays, lists etc when passon to Velocity, i.e.
context.put("entry", some_list/some_array);
have FAILED.
This is what I did:
1. I have a Vector A; <------ context.put("entry", A) is OK with Velocity.
2. But I need to do some work on the data in A. So:
3. Extract Object a = A.elementAt(some_position); Do what I have to do AND:
4. Put it back into another Vector B.
B.add(modified_a);
context.put("entry", B);
BUT velocity does not like it.
I tried to vary Vector B with Array B, List B, nothing worked, anyone know
where I have done wrong?

or you could probably use an array of an array directly.

Re: Howto create a VECTOR for Velocity
Posted by Scott Eade <se...@backstagetech.com.au>.
Michael,
Most people on this list will argue strongly that your velocity templates
should contain only formatting code and never processing code - put this
instead in a pull tool or the screen classes.
Provide a method in your pull tool that provides the data you need - this
might instantiate and populate a Vector or whatever else you want to do.
I don't really understand the specific example you are attempting to
describe below, but an object is an object, whether it is created by
Turbine, Torque, your pull tool or screen class - and Velocity should be
able to access it and work with it provided that you have somehow made it
available to the context.
One thing you can't do in velocity (and shouldn't be able to do) is
instantiate non-primitives (other than String). You can create references
to objects, arrays, Strings and ints using #set.
BTW: You may like to use ArrayList in preference to Vector.
HTH,
Scott

Re: Howto create a VECTOR for Velocity
Posted by Eigen Technology Pty Ltd <mi...@eigentechnology.com>.
Thanks for the advice,
I knew the Pull Tool part. But my question was on how to create a Vector
in this PullTool.
Say you have 100 rows of data each with 6 cols in your
$DateTool.TodaysDate()
function. Before you pass it to Velocity, you have to package them in a
Vector first, right (correct me if I am wrong)? If this vector is not from
Turbine, how do you create it?

Re: Howto create a VECTOR for Velocity
Posted by David Worms <da...@simpledesign.com>.
you have to configure your TR.properties file. Configure the pull
service by adding a line like
services.PullService.tool.<scope>.<id> = <classname>
for example:
services.PullService.tool.request.date=com.clavie.myEvents.tool.DateTool
then, you should be able to access it in Velocity with sth like:
$DateTool.TodaysDate()

Howto create a VECTOR for Velocity
Posted by Eigen Technology Pty Ltd <mi...@eigentechnology.com>.
When Turbine extract data from a database, it creates a Vector and returns
for Velocity to display.
If I want to write a Java Utility, some tabulated calculated results are
to be passed on to Velocity, i.e. Vectors not created by Turbine, how
should I do it.
I tried:
Vector TEST=null;
etc....
for(i=0; i < somelimit; ++i) {
TEST.add(someobject(i));
}
etc....
return TEST;
Velocity displays nothing, help is much appreciated.

I guess this question can be addressed by the author of Turbine :-).
Since we can extract data by doing:
$document.XXX in .vm
the author must have a way of extracting data from the $document object.
Since I can't extract the data using my methods (and/or all those who has
offered me assisstance), it might help if I would be allowed to have a
look at the Turbine's source code.

Wei,
I tried
$document.getClass().getName()
it just return with the path to one of my class files:
org.mycompany.medici.om.Contact
where Contact is the name of the Database Table. What does this mean?

I think the last resort is to find out what the objects really are. This
can be done by using getClass().getName() on each Object in your
Collection. This can be done in vm file, and class name of each Object
will be printed.
Once you find out what they are and call their own methods to get the
fields you need. Hope this helps.

Re: A Java Question... not working.
Posted by Eigen Technology Pty Ltd <mi...@eigentechnology.com>.
Thanks to all,
I have tried all that suggested, unfortunately none worked ... What Wei
has suggested compiles OK, but nothing got returned. Here is my procedure
again:
1. Extract data from DB using a PullTool
2. Data is encapsulated in a Vector.
3. Each element in this Vector contains a single row of data (multiple col).
4. Try to extract a single col of datum from a single row.
The first time when I perform the elementAt(1), it is OK, it returns a
list of Objects. I can get Velocity to display its contents by
$documents.XXX
If I perform toString() on these objects, I get only the Address of the
objects. If I perform another elementAt(x), nothing got returned. I am a
bit confused here, how is object-strings converted in general?
thanks

Re: A Java Question...
Posted by Wei He <we...@ldeo.columbia.edu>.
Your right hand side is an Object, you need to do a cast. That is:
String test = (String)((Object)docs.elementAt(1)).elementAt(1);
or
String test = ((Doc)docs.get(1)).getDocString();
or
String test = (docs.elementAt(1)).elementAt(1).toString();
It depends on the type you have for the first field in your doc object.
If it is a BigDecimal, direct cast may not work, toString() will do.
You see my point.
Hope this helps.

I could possibly write a servlet to extract and then filter the data, but
I think that would defeat the purpose of having Turbine in the first
place.
I tried:
String test = ((Object)docs.elementAt(1)).elementAt(1);
return test;
the compiler did not complain, but Velocity rejected it. Really running
out of ideas. Any suggestion would be appreciated.
cheers

Try:

I am going to assume that you will be using Velocity and not JSP or some
other type of view.
My comments are inline.

This is the default page that Turbine will render if a specific page is
not request. For example, if you accessed the followjng page
http://www.myapp.com/blah/servlet/sampleapp (just an example), you will
get the template listed in template.homepage. Think of this as
Turbine's, index.html.

Ignore this. It is only used if you do not have a template.homepage.

This is really only used in the default login action and the secure
session validator (not enabled by default). For the login action, this
is used on an invalid login attempt. This is where the user will be
sent if the login fails. This should normally, be you login template.
Make sure that somewhere on your template you display
$data.getMessage(). When the login fails, data.setMessage() is called
to store the reason for the login failure.

Ignore. This is only used when template.login is not specified.

This template is displayed when an exception is thrown during the page
generation. This could be an action that threw the exception, your
screen class, etc...
The actual exception is added to the context as "processingException"
and the stack trace as "stackTrace".

Ignore.

Leave this as the default. It is used by the session validator classes
in cases where a user tries to submit stale form data. This screen is
then displayed to the user. This functionality is not enabled by
default. To use it, you would add a hidden form field called
_session_access_counter in your form. The value should be set to
$data.User.AccessCounterForSession.
If you are really interested in using this, look at the source code for
a better explaination of how it really works. I have never used it,
myself.

Not sure...

Turbine handles the login and logout actions specially. If you write
your own implmentation of the login or logout actions, you will need to
update this setting with the new class name.

How to configure template for web page?

In TurbineResources.properties, what these variables mean? And what are they
used to do?
I am just confused by them.

FWIW in commons collection's CollectionUtils class there is a method,
select() that will select objects from a collection given conditions
you specify.
