Jato 1.1 to Jato 1.2
Hi,
we are doing a migration project that includes Jato 1.1 to
Jato 1.2. what are the issues and problems for doing this
conversion. And any one did it previously.
(copied from my Yahoo Group response)
The only thing I can give some info on is the JATO 1.2 to 2.0.
First, the JATO runtime has very few changes in it from 1.2 to 2.0. Your app will typically run as is under 2.0. All you really need to do is replace the JATO JAR file. There may be a few minor details, but should not be any show stoppers.
There are some new API's in 2.0, but the old stuff is just deprecated. There are some additionally API's to make JATO toolable, but have no affect on the runtime.
The Studio really reduces the effort it takes to create JATO components. Lots of code gen that is easily manipulated via visual property editor. However, you still have the flexibility to hand code what you want.
The way to bring your 1.2 app into a JATO 2.0 app is as follows:
- use the Studio to create a new application with the same package structure as your current app
- copy your view beans, tiled views, models and custom classes into the new package structure.
Now this allows you to build new objects using 2.0 techniques (visual point/click creation) and the new components will run along side your old components. The old components will not show up in the Studio tool like the new components will. In other words, a newly created view bean is recognized as a "JATO ViewBean" because it has an extra design time meta data file that desribes it. Your older ViewBeans will not have this file and therefore, will only be recognized as a regular Java class.
Creating this meta data file is not really something that can be reasonably done by hand, unfortunately.
If your app will not grow, then go ahead and start using JATO 2.0 runtime, but don't worry about the Studio aspect. But if you plan to expand the app, it would be beneficial to continue with the Studio tools.
Does anyone have some "real" world experience they can lend to the forum.

Re: [iPlanet-JATO] from a non jato application to jato application
Without getting into the details, the session id is passed around in a
cookie, but once you leave your JATO app "sandbox", you no longer have
access to the same session. This is not a JATO limitation, but a J2EE
spec constraint. The war file creates a Servlet Context. Other servlet
contexts have separate session sandboxes. If you deployed all your apps
within the same war file, your sessions would be mutually accessible.
or
You could do something like use a Session EJB and pass its reference
between apps I suppose.
Also, see JATO Tip #0011 for forwarding to a "non-JATO" target.
Hopefully, my reply will open up a conversation for more solutions,
ideas, if what I have proposed is insufficient.

Note - The file upload notification refers to Jato 1.1 not Jato 1.2 UML
I uploaded some Jato 1.1 UML diagrams at the request of one of the group
participants. Unfortunately, these diagrams are slightly out of sync with Jato
1.2 and therefore have not been included in the Jato 1.2 documentation.
However, the diagrams may provide some assistance to those attempting to come
up to speed on the Jato framework. Just bear in mind that the details for Jato
1.2 are slightly different.
[Non-text portions of this message have been removed]I found a working solution, but better solution are also welcome
I had to have fr_CA not only in utf8 but also in iso88591. I had to modify the /etc/rc.conf this way :
LOCALE="fr_CA" <<<<<<<<<<<<<<
HARDWARECLOCK=""

To preserve the english US language system wide, I had to add the following line in the /etc/profile :

RE: [iPlanet-JATO] Href click & tiled view display
Srinivas,
I hope that I am not oversimplifying your first question; repost if I do not
answer your question. Independent of JATO, HTML Form button sumbits will
include the scraping of data off the form input fields; the data will passed
as part of the body of the HTTP request. Therefore, you would expect to
receive all your inputs during the Button submit. In the case of a button,
a HTTP POST request is invoked. Href clicks, only submit the NVPs which are
encoded on the HREF URL. Therefore, it is impossible (under normal
circumstances) to retrieve the inputs from the FORM during the Href click.
In the case of a Href, a HTTP GET request is invoked. Some customers have
used a pattern in which Javascript is used to capture the Href onClick()
event to perform some runtime modifications to the HREF URL before the HTTP
GET request is submitted. I recommend to always have the LogProxy2 utility
running during development so that the HTTP requests and repsonses can be
debugged. If you setup the LogProxy2 (downloadable from this Group's Files
repository) then you would see the HTTP requests in the LogProxy2's console
window.
TiledView question: Remember, each TiledView requires a "primary
DatasetModel" which it uses for iteration of the tiles. It can be
confusing, but the API call of
<ContainerView>.getDefaultModel()
has no relation to the implementation class called DefaultModel. See the
Javadoc (excerp below)
/migtoolbox-1.1.1/doc/jato/api/com/iplanet/jato/view/ContainerView.html#getD
efaultModel()
"Returns this view's default model. The default model is typically used by
DisplayField children for default value storage (if they are not bound to
any other model). This method should always return a valid model instance.
Note that the default model need not be an actual instance of DefaultModel,
although this is usually the case."
Both of your TiledView's (inner and outer) are ContainerViews, each having
their own property for [get/set]DefaultModel(). Likewise, the ViewBean
parent of the outer TiledView is a ContainerView as well. With these facts
in mind, consider the behavior of the ModelManager. The ModelManager will
ensure that only once instance of specifically named model will be provided
during a request scope. Therefore, everytime that you make a call to
<ModelManager>.getModel(SomeModel.class)
no matter how many times you make this call during a request, the
ModelManager will ensure that you get the same object reference back.
Implicitly, you are asking for a Model with the exclusive name of
<ModelManager>.getDefaultModelInstanceName(SomeModel.class)
I believe that your problem is that you have the Primary Model of both the
inner and outer TiledView's set to the same instance of the DefaultModel
class. Therefore, the TiledViews are tripping over each other because they
are using the same Primary model. What I would do is change the constructor
of each TiledView to set an exclusive Primary model
// add to constructor of outer TileView
setPrimaryModel(getModelI(DefaultModel.class,"outer")
// add to constructor of inner TileView
setPrimaryModel(getModelI(DefaultModel.class,"inner")
remember to set the "size" of the Primary Model appropriately in the
beginDisplay() event of each TiledView before calling super.beginDisplay()

Subject: [iPlanet-JATO] Href click & tiled view display
Hi,
I'm facing the following two problems in JATO. Your help will be
appreciated.
1) Clicking a HREF.
I have a button and a href in a page. When I submit the page by
clicking the button, I'm able to
get all the user entered data (form elements) in handler method.
However, when I click
the href and I try to retrieve the data entered by the user in my
corresponding handler method, I'm
getting blank values.
How would I be able to get the user entered data upon clicking of a href
? I'm copying the sample
code for your reference.
// This returns me 5 values entered in the 5 tiles by the user.
public void handleBButtonRequest(RequestContext req)
throws ServletException, IOException
try
System.out.println("button clicked..");
pgSampleTiledView tiledView = getSampleTile();
System.out.println("\n\n\n\n@@@@@@@@@@@ No of tiles >>>
"+tiledView.getNumTiles());
int n = tiledView.getNumTiles();
for (int i=0; i<n; i++)
tiledView.setTileIndex(i);
System.out.println(i+".
"+tiledView.getTbValue().getValue().toString());
this.forwardTo(req);
catch (Exception ex)
ex.printStackTrace();
// This returns me 0 tiles and doesn't get into for loop
public void handleLinkModifyDistributionRequest(RequestContext req )
throws ServletException, IOException
try
System.out.println("href clicked..");
pgSampleTiledView tiledView = getSampleTile();
System.out.println("\n\n\n\n@@@@@@@@@@@ No of tiles >>>
"+tiledView.getNumTiles());
int n = tiledView.getNumTiles();
for (int i=0; i<n; i++)
tiledView.setTileIndex(i);
System.out.println(i+".
"+tiledView.getTbValue().getValue().toString());
this.forwardTo(req);
catch (Exception ex)
ex.printStackTrace();
2) Tiled view display
I have tiled view inside another tiled view. Based upon the data
retrieved from the database, lets say, the outer tile needs to be
displayed twice and the inner tile 3 times and 1 time.
For Ex: Lets say, the desired output from these tiled views is as
follows
STOCK INVESTMENT
stock name1
stock name2
stock name3
OTHER INVESTMENT
other investment1
The outer tiled view displays the investment type headings (STOCK
INVESTMENT or OTHER INVESTMENT) and inner tile
displays the actual stock names or the other investment names. Both
the tile views are bound to a default model. In the begin display
of these tiled view I'm setting the size of the model as
getPrimaryModel.setSize(requiredsize).
If i display 3 records in the inner tiled view in the first iteration
and i try to display 1 record in the second iteration, it displays 3
records
properly the first time but it doesn't display any records second
time. super.nextTile() returns false right away second time.
But If I try to display 1 record in the first iteration and 3 records in
the second iteration as below, it works fine.
STOCK INVESTMENT
stock name1
OTHER INVESTMENT
other investment1
other investment2
other investment3
Please let me know what could be the problem.
Thanks

What you are asking to do is EXACTLY what one of the primary value
propositions of the JATO design. The JATO Overview 'whitepaper'
specifically points this out as a limitation of other MVC frameworks. The
constructors of the Views require the designation of a Model; this is where
you would hook your Views (DisplayFields) into various Models. Please note
that there is no coupling of the Views and Models so there is a many to many
relationship (of your choosing). Please note that the 'accessor' methods
(setters and getters) [other than the Model interface prescribed getValue()
setValue() getValues() setValues() methods] are no related to the
DisplayField design pattern per se. The DisplayFields will manage data on
the request and response cycles using the getValue()/setValue() methods.
This is what lets the model view relationship plugable. The accessors in
the Model are not required for the View pattern. The implementation of a
specific Model's getValue()/setValue() may be to utilize the special
accessors...but they are not used by the DisplayFields directly.

Conversion of 1.2 JATO project (non-Forte IDE) to S1AF (JATO) 2.0
JATO Team,
First of all, thank you very much for the Studio integration. It
looks very promising in terms of development time consumption,
deployment to S1AS7, etc., etc. It is impossible to observe all
advantages for so short period of time.
The SOAF (JATO) 2.0 is installed on the top of the Sun ONE Studio 4,
update 1 (EE) with JDK 1.4 along with the Sun One Application Server
7 (W2000). Everything looks okay, at least all basic tasks listed in
the "Getting Started" manual (project/view/model creation, basic db
connection, running of a test application with the usage of the
Studio's default Tomcat container, etc.) work proper.
During the installation of S1AF module on the top of the Sun ONE
Studio 4, update 1 (EE) I've got an invitation to convert the
existing project to the new environment. As I realized the only JATO
project integrated/created with Forte IDE is applicable for this auto-
conversion (please correct me, if I am wrong. It could solve a lot of
my problems).
Since we are using JBuilder5 IDE and our JATO 1.2 project is
integrated with this IDE I manually re-created project in the Studio
with its file structure, adjusted the project web.xml file, etc. This
new project looks like a proper one (Studio recognize all methods,
fields, bean patterns, e.g.) except at least one "small" thing. All
java files (project viewBeans, Models, custom viewBeanHelpers a.k.a.
pure java) came up with the same wizard image:java class. Stutio with
the S1AF module reserves the special images (and appropriate studio
properties, of course!) for View and Model. Namely this allows to see
the following structure for a ViewBean, for example, in the Studio:
Modules
ProjectName.ModuleName
FooViewBean
JavaSource
JSPs
Non-Visual Components
View Components
On the other hand, I could add either new View or Model in my
manually converted project and add any View Component or bind the
Model fields, for example. Also, the ProjectModuleServlet has been
converted proper. I tried to convert each View/Model class inside the
Studio to its proper wizard image and failed. Addition of a View
Components (with an appropriate code fragments) via the Studio or
auto-binding of model fields is an essential part of 2.0 and should
drastically speed up the development process as it is designed.
Questions:
1. What I missed in my manual conversion of 1.2 JATO project to the
SOAF (JATO) 2.0 realm? What should I correct in my JATO 1.2
compatible classes (Views and Models) to be recognizable by Studio
wizard (JATO 2.0)?
To be more specific. Some deltas between JATO 1.2 and JATO 2.0 are as
follows (related to a ViewBean):
====++++++++++++++======
JATO 1.2 viewBean extension upon creation:
public class FooViewBeanViewBean extends ViewBeanBase
implements ViewBean
========================
JATO 2.0 (S1AF) version: viewBean extension upon creation:
public class FooViewBean extends BasicBeanBase
====++++++++++++++======
JATO 1.2 viewBean createChild(...) method for one static looks
like:
protected View createChild(String name)
if (name.equals(CHILD_STATICTEXT1))
StaticTextField child = new StaticTextField
(this,
getDefaultModel(),
CHILD_STATICTEXT1,
CHILD_STATICTEXT1,
CHILD_STATICTEXT1_RESET_VALUE,
null);
return child;
========================
JATO 2.0 (S1AF) version: viewBean createChild(...) is renamed (as
a least) to createChildReserved(...):
protected View createChildReserved(String name) {
if (name.equals(CHILD_STATICTEXT1)) {
com.iplanet.jato.view.BasicDisplayField child =
new com.iplanet.jato.view.BasicDisplayField(this,
STATICTEXT1);
return child;
====++++++++++++++======
JATO 1.2 viewBean registerChildren() method for the basic field
types looks like:
private void registerChildren() {
registerChild(CHILD_STATICTEXT1, StaticTextField.class);
registerChild(CHILD_TEXTFIELD1, TextField.class);
registerChild(CHILD_BUTTON1, Button.class);
========================
JATO 2.0 (S1AF) version: viewBean registerChildren() method:
private void registerChildren() {
registerChild(CHILD_STATICTEXT1,
com.iplanet.jato.view.BasicDisplayField.class);
registerChild(CHILD_TEXTFIELD1,
com.iplanet.jato.view.BasicDisplayField.class);
registerChild(CHILD_BUTTON1,
com.iplanet.jato.view.BasicCommandField.class);
Is it correct to say that all existing custom Views/Models
(compatible with JATO 1.2) should be converted to their JATO 2.0
variants to be visible by the Studio?
On the other hand, fast overview of 2.0 API shows that the JATO 1.2
is a sub-set of the 2.0 (BasicViewBean extends ViewBeanBase, for
example). What exactly (only deprecated methods?) should be adjusted
in the project code (1.2), if necessary, to be visible by Studio as a
View or Model component?
2. Where it is possible to find the list of deprecated methods (from
JATO 1.2 to JATO 2.0 versions). It is difficult sometimes to compare
two versions of API docs (1.2 and 2.0) or compare logs between
versions. Also, JATO 2.0 is significantly larger than 1.2 version. If
the later obviously inherits the ND conversion stage (via the
previous versions), the former obviously has additions incoming from
the integration with the Studio (a.k.a. Forte 4.0).
3. What is the current/future Sun/JATO Team policy with regards to
JATO source code access (version 2.0, at least)? The reason of this
question is as follows: in order to display dates formatted on the
screens we adjusted a couple of JATO 1.2 core classes, for example.
The only minimal, absolutely necessary changes in JATO 1.2 was made,
but anyway...
Sorry for so long multiple question. As Todd wrote in his
announcement mail: "We think you will be very pleased with the new
product...". This is exciting moment, I believe, for JATO Team as
well as for any team involved into the conversion of the full size
application/product from ND to J2EE realm with the JATO as
an application framework (1.0, 1.1.x, 1.2.X, and 2.0 finally). The
last step is left in this spiral process to enjoy the ND_Studio
attractive features in the open source environment.
Thank you very much in advance.
Vladimir IvanovI'll get some file templates ASAP and provide them to the group.
As for source code, I'm not sure what the policy is. JATO 1.2 is very
close to what JATO 2.0 is, so that should suffice for now.
The community will be informed when we know more about source availibility.

Craig,
Thank you for the answer. To be honest with you I tried to do exactly
the same: I created the small test project and made an attempt to
adjust the existing *.xml files to the new ones. I got some results,
otherwise I couldn't even see my original 1.2 project in the Studio.
Since I am a newcomer in the Studio, I definitely missed something in
my adjustments. I'll try to observe my changes with the fresh head.
On the other hand, I am afraid that my samples are very pure. If you
could post or send me examples of jatoapp.xml and web.xml files (say
for any of you test project) or excerptions from them with the
appropriate patterns (ViewBean and Model peers, at least), I would be
very appreciated. My mail is: vivanov@b...
In the worst-case scenario I see the workaround: to re-create the
project for one of our releases with the Forte 4.1 IDE and auto-
convert it into the JATO 2.0/Studio world using the Studio
facilities. We must get the current project fully
integrated/converted with/to the Studio (at certain point) because,
first, we expect massive coding with the GUI components involved soon
and, secondly, we have around thousand classes related to JATO only
(and a lot of extras).
Coming back to the question #3 from this post. Now we have full
access to the version 1.2, not only to the JATO 1.2 jar file(I
explained some reasons below). Would we expect the same Sun/JATO Team
policy with JATO 2.0?
Thank you again,
Vlad

It doesn't appear that anyone has responded to this so I am goingto
give you the short answer:
The reason you don't see your ViewBeans and Models showing up with
there "wizard created" icons is because of just that. They weren't
created via the wizards. The wizards create xml formatted filesthat
contain metadata of how/what to generate for the ViewBeans and
Models.
ViewBeans will have a .viewbean fiel, Models will have a .sqlmodel
file (for SQL Models), etc. The content of these files describesthe
code that needs to be generated in the corresponding Java classfile.
So LoginViewBean.java will have a peer LoginViewBean.viewbean file.
The code that is generated is place in protected code blocks thatcan
not be modified in the Studio and should not be modified outsidethe
Studio because the code will likely be regenerated and custom mods
inside the protected blocks will be lost.
Now you can make a JATO 1.2 app appear in the Studio just like aJATO
2.0 app by adding a jatoapp.xml file with the proper content and
adjusting your web.xml properly, but it's much more work to getyour
v1.2 ViewBeans and Models to show up like wizard created versions.
Furthermore, even more work to get the display fields to show up
visually.
The good news is that v1.2 ViewBeans will work with newly wizard
created ViewBeans. And if you do go through the trouble of making
your ViewBeans Studio visible like your wizard created ViewBeans,
adding new display fields visually will work along side yourmanually
created fields.
Try creating a new JATO app using the Studio wizards and then go to
the Filesystems tab and look for the jatoapp.xml file and theweb.xml
file.
I am looking for an email that I have that explains how to do a
partial, manual upgrade.
Also, you will get rid of your JATO 1.2 jar and replace with theJATO
2.0 jar in your lib dir.
Hope this will suffice for now.

JATO Team,
First of all, thank you very much for the Studio integration. It
looks very promising in terms of development time consumption,

The SOAF (JATO) 2.0 is installed on the top of the Sun ONE Studio4,

hi ...
i have just about started using jato in conjunction with S1Studio
and find it a real great asset ...
we are trying to build custom jato components which can be packaged
into a jar file and used like any other standard jato component ...
e.g. i have developed this date component which is basically a
composition of 3 comboboxes - one each for m/d/y ...
to render these 3 comboboxes i have a "date" tag (DateTag.java)
which basically includes a file Date.jsp in the parent jsp - the
contents of Date.jsp:
<jato:pagelet>
<jato:combobox name="month"/>
<jato:combobox name="day"/>
<jato:combobox name="year"/>
</jato:pagelet>
The problem with this approach is that I can't package a JSP in a
jar since the web server would not be able to determine the path to
the jsp ...
Can any of u direct me here? ... Also, if u have an example of a
similar packaged custom jato component - that'd be of great help!
thanks much,
keyurThanks Craig ... but Somehow this didnt work - maybe I didnt follow
the steps correctly ... here is what i did:
the jar file -> date.jar
date.jar has .class files arranged according to their package
names ..
there's also the "COMP-INF" directory ...
in addition to these - i added another folder called "webapp" ...
and within "webapp" i housed the JSPs ...
i then copied date.jar to <context root>/WEB-INF/lib folder and
started the server ...
however, the web server didn't extract out the JSPs ... did i go
wrong somewhere? .... am i to do something other than this - like
create the jar with some special parameter or change some
configuration in the server?
thanks!

Keyur,
You are in luck. There is a way to bundle the JSPs (or any web resources
like images and other jar's) in the component jar file so that the tool
will expand them properly into your web application's doc root.
It's not officially documented yet, as is the case with creating
components in general, but here's what you do:
You have the ability to extract arbitrary files from a component library jar file into the web app's file system. This allows
libraries to automatically unpack files like additional jars,
images, pagelets, etc. All that's needed to take advantage of this
new feature is to create a hierarchy of files in the complib under
a "webapp" directory (off the root). The files under that directory
will then be automatically extracted into the web context's
filesystem.

For example:
/webapp/test/foo.html
will extract to
<context root>/test/foo.html
and the following
/webapp/WEB-INF/lib/foo.jar
will extract to
<context root>/WEB-INF/lib/foo.jar
Anything not under the "webapp" dir in the component jar file will stay packaged in the jar file.

Does that make sense?

RE: [SunONE-JATO] handle...Request() - in different TiledView?
I need probably to reorder Parent-Child relationships,
I have now
- ViewBean
---MenuItemsTiledView.class
---OrderCacheTiledView.class
---Button.class (append)
I will try to have
- ViewBean
---MenuItemsTiledView.class
------OrderCacheTiledView.class
---------Button.class (append)
And I will have to change:
<jato:tiledView name="MenuItems"
<jato:tiledView name="OrderCache"
<go method="post" href="<%=response.encodeURL
("../member/MenuItems") %>">
<postfield name="MenuItems.append" value=""/>
<postfield name="MenuItems.menuItemId"
value="<jato:getDisplayFieldValue
name='MenuItemId'/>" />
</go>
I think it is strict rule to have the same parent-child relationships in
JSP like as in classes
May I have more freedom like as with <jato:text name="...">, where name
could be relative (to parent, to container), absolute?

Subject: [SunONE-JATO] handle...Request() - in different TiledView?
Hello,
I use ViewBean, and two child TiledViews (WML sample).
<jato:tiledView name="TiledView1"
type="mobiledb.member.MenuItemsTiledView">
<go method="post" href="<%=
response.encodeURL("../member/MenuItems") %>">
<postfield name="MenuItems.append" value=""/>
<postfield name="MenuItems.menuItemId"
value="<jato:getDisplayFieldValue name='MenuItemId'/>" />
</go>
I think, "handleAppendRequest()" will work within TiledView1 (I didn't
try yet, I have this handler in ViewBean).
But, logically, better place for it is TiledView2 which contains cached
appended records...
I can have handler in ViewBean redirecting into TiledView2 of course,
What is the best way?
Thanks,
Fuad

OK, I solved it (for WML),
If I use "virtual buttons" on JSP page (within <jato:tiledView.../>
tag), and this buttons are child of MyTiledView class (which is child of
MyViewBean), I can use
<postfield name="MyJspPage.MyTiledView.Append[2]" value=""/>
for emulation of button.
I don't use MyViewBean.MyTiledView.Append[2]!
Next step: I have to understand what to do with index in
MyTiledView.handleAppendRequest... Code seems harder than putting Button
and Handler in main MyViewBean...

Re: [iPlanet-JATO] Re: Retrieving all Values from a Tiled View
Todd,
Let me try to explain you this time. I have a text field in a TiledViewBean.
When I display the page, the text field
html tag is created with the name="PageDetail.rDetail[0].tbFieldName" say
five times/rows with same name.
The html tags look like this.
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
When the form is submitted, I want to get the text field values using the
method getTbFieldName().getValues() which
returns an array object[]. This is in case where my TiledViewBean is not
bound and it is working fine.
Now in case when my TiledView is bound to a model, it creates the html tags
as follows.
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[1].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[2].tbFieldName" value=""
maxlength=9 size=13>
Now when I say getTbFieldName().getValues() it returns only the first
element values in the object[] and the rest of the
values are null.
May be we need to create a utility method do get these values from
requestContext.

Without further clarification, I can say that the setValues() methodsNEVER

multiple fields on the same row. Perhaps what you are seeing is theeffect
of default values. Model that derive from DefaulModel have the ability to
carry forward the values set on the first row to other rows in lieu ofdata
in those other rows. This behavior is for pure convenience and can be
turned off, and it is turned off for the SQL-based models.

ie Something that returns an Object[] or Vector just like ND returned a
CspVector. I tried using the getValues() methods but that allways returns
a
single element array containing the first element.
(I think now, that method is used for multi selecteable ListBoxes)Actually, no. We can add this in the next patch, but for now, I'd recommend
creating a simple utility method to do the iteration on an arbitrary model
and build the list for you.

Re: [iPlanet-JATO] Sorting a resultset
Steve,
Todd will probably address this more, but to set the stage for the discussion,
I will chime in. As per your scenario "say a user wants to resort the results
by some other column" , I think there needs to be some clarification on the
life cycle of the model. You scenario implies that the user sees the data and
then submits a request to sort the data. This implies that the access to the
same data is spread across two HTTP requests.
Unless explicitly or implicitly stored in session, the Model is a per request
object. Therefore, under ordinary circumstances a new instance of Model is
constructed per request and populated as needed. This is done for scalability
reasons. Most applications would not scale properly if all model instances were
kept around in session per user. There is also the issue of data integrity, a
model stored in session may not reflect the current state of the RDBMS from
which the data was previously retrieved, perhaps minutes before. So, the
default action is to instantiate a new model and repopulate that model The
normal solution would be to apply the sort criteria to the data retrieval at
that point.
What I described above is the norm and the default.
If you have compelling reasons to prefer a single retrieval style, you have to
be prepared to store the Model data in session. There are several methods
within the ModelManager class which assist in this regard. You can see them
described in the java doc.
Also bear in mind that the SQLModelBase typically copies the data from the JDBC
result set into JATO specific local storage. This is done because the JDBC
result set is not as flexible as developer needs and requires the JDBC
connection to remain open while it is used.
I suspect that Todd will describe how you can manipulate the underlying JATO
specific local storage to change the order. I just wanted to make sure you
understood the life cycle issues involved and had justification for deviating
from the default.
Also, I'm still waiting for followup on the defaultCommandChild issue - we'd
like to fix it for JATO 1.2.1 if it is a problem and so far your case is the
only one we have heard of.

Subject: [iPlanet-JATO] Sorting a resultset
If I want to sort a result set (Model) after the search has taken
place (say a user wants to resort the results by some other column),
can this be done without issuing another query? The reason I ask is
that the next() method in the ResultSetModelBase calls synchronizeRow
(), which resets the row, which sounds like a sort done outside of
the SQL would be reverted.

To answer your question - it should work as you described. Some of the JatoSample make use of the defaultCommandChild. Can you try

Re: [SunONE-JATO] How to use a tiled view without a model
John,
Check out the docs for DefaultModel. There is an appendRow() method.
So get your tiledview's primary model (the tiledview's primary model
should be set to use an instance of DefaultModel), model.appendRow(),
then model.setValue("fieldname", value) for each value.
Rinse, repeat as needed.

Re: [SunONE-JATO] Re: How to use a tiled view without a model
I'm not sure what is different for you now. You still parse the string
and put it into a data structure. Before the data structure was a
vector, in JATO its just a model with a "hidden" data structure (a hash
map).
MVC only really comes into play when you talk about where your write
this code, and where the data structure is being stored. So really, JATO
takes care of half of the MVC'ness of it all (where the data is store).
You just decide where to be the code to populate the model.
Make sense?
Is there something different required of you in JATO in this scenario
that I am not grasping?

Hoskins, John D. wrote:
Thanks for the feedback.
The problem I was solving involved a single string, which contained
delimited subsets of information.
The string looked like
this:"time|analyst|description|time|analyst|description|..."
In ND, I parsed it apart into it's components (time vector, analyst vector,
description vector), populated the repeated.
With JATO, how would I make a model for something that doesn't have a
database component like this?
I'm pretty new to this MVC thing, so bear with me.

Subject: Re: [SunONE-JATO] Re: How to use a tiled view without a model
I guess the only thing "weird" (for lack of a better term) about what
you are doing is that your are populating the model on the "display
cycle". Typically, the cycle goes like this:
Request -> populate model -> update data store -> retrieve data to
populate model -> display data
some of the above steps are optional but hopefully you get the point I
am making.
So what you are doing is:
Request -> populate model/display data
If it works for you, then it's not necessarilly wrong. But I would
probably have my model populated before I forwarded to the target
(displaying view bean) or at a minimum, in the begin display event of
the view bean or the tiled view, but not during the iteration of the
tiled view.
