Re: [iPlanet-JATO] jato classes serializable

Unless Todd, Mike, or Matt have slick answer to make it work, my only
solution would be to switch from using the objects themselves and
reference by name instead. I don't know exactly what your Utility class
is doing or how the fields use the Utility class, so I can not be
specific in what you should do.
I fear that I may be taking on too much work by asking, but maybe you
could send me the Utility class (send to me directly as Yahoo Groups
doesnot allow attachments: craig.conover@s...).
I'll take a quick glance at it. Maybe I can make some suggestions to
minimize your migration efforts.

In ND, we had a utility class written whose member variables were visual
objects. This utility object is used to display or not display its elements
depending on user action. The utility object was being put into session.
It could have been implemented in a different way, by storing visual object
names instead of objects themselves. But when we migrated, we tried to keep
re-coding to the minimum and ended up replacing ND visual objects
withcorresponding jato visual objects and ran into this problem.
Since all the jato visual objects extend from DisplayFieldBase which inturn
extends from ViewBase, i started looking at ViewBase and did not understand
why the variable was made transient. Hence the question.

What is your requirement that these be serializable?
The views do not store any values, that is what the model is for, and
they are created lazily as needed.
Is there something you were doing in ND that required it. It is very
likely that you do not need to do it anymore with JATO.
If you are using JATO1.0, you are highly encouraged to start using JATO
1.2. If you are using the iMT, it has an upgrade tool for 1.x to 1.2.

I'll leave the transient parentViewBean to Todd or Mike to justify. But,
again, what is the need for it to be serialized?

Is this change made in jato1.1? It will be good to have this feature as

Also in com.iplanet.jato.view.ViewBase.java, why has this variable been
made
transient?

Re: [iPlanet-JATO] Re: Use Of models in utility classes - Pease don't forget about the regular expression potential

Namburi,
When you said you used the Reg Exp tool, did you use it only as
preconfigured by the iMT migrate application wizard?
Because the default configuration of the regular expression tool will only
target the files in your ND project directories. If you wish to target
classes outside of the normal directory scope, you have to either modify the
"Source Directory" property OR create another instance of the regular
expression tool. See the "Tool" menu in the iMT to create additional tool
instances which can each be configured to target different sets of files
using different sets of rules.
Usually, I utilize 3 different sets of rules files on a given migration:
spider2jato.xml
these are the generic conversion rules (but includes the optimized rules for
ViewBean and Model based code, i.e. these rules do not utilize the
RequestManager since it is not needed for code running inside the ViewBean
or Model classes)
I run these rules against all files.
See the file download section of this forum for periodic updates to these
rules.
nonProjectFileRules.xml
these include rules that add the necessary
RequestManager.getRequestContext(). etc prefixes to many of the common
calls.
I run these rules against user module and any other classes that do not are
not ModuleServlet, ContainerView, or Model classes.
appXRules.xml
these rules include application specific changes that I discover while
working on the project. A common thing here is changing import statements
(since the migration tool moves ND project code into different jato
packaging structure, you sometime need to adjust imports in non-project
classes that previously imported ND project specific packages)
So you see, you are not limited to one set of rules at all. Just be careful
to keep track of your backups (the regexp tool provides several options in
its Expert Properties related to back up strategies).

Great response. By the way, the Regular Expression Tool uses thePerl5 RE
syntax as implemented by Apache OROMatcher. If you're doing lotsof these
sorts of migration changes manually, you should definitely buy theO'Reilly

superbly effective at tackling this kind of migration task.

Please bear in mind that this statement is not totally correct:
Since the migration tool does not do much of conversion for
these
utilities we have to do manually.Remember, the iMT is a SUITE of tools. There is the extractiontool, and
the translation tool, and the regular expression tool, and severalother
smaller tools (like the jar and compilation tools). It is correctto state
that the extraction and translation tools only significantlyconvert the
primary ND project objects (the pages, the data objects, and theproject
classes). The extraction and translation tools do minimumtranslation of the
User Module objects (i.e. they repackage the user module classes inthe new
jato module packages). It is correct that for all other utilityclasses
which are not formally part of the ND project, the extraction and
translation tools do not perform any migration.
However, the regular expression tool can "migrate" any arbitrary
file
(utility classes etc) to the degree that the regular expressionrules
correlate to the code present in the arbitrary file. So first andforemost,
if you have alot of spider code in your non-project classes youshould
consider using the regular expression tool and if warranted adding
additional rules to reduce the amount of manual adjustments thatneed to be
made. I can stress this enough. We can even help you write theregular
expression rules if you simply identify the code pattern you wish to
convert. Just because there is not already a regular expressionrule to
match your need does not mean it can't be written. We have notnearly
exhausted the possibilities.
For example if you say, we need to convert
CSpider.getDataObject("X");
To
RequestManager.getRequestContext().getModelManager().getModel(XModel.class);
Maybe we or somebody else in the list can help write that regularexpression if it has not already been written. For instance in thelast
updated spider2jato.xml file there is already aCSpider.getCommonPage("X")
rule:

<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getViewBean($1ViewBean.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
Following this example a getDataObject to getModel would look
like this:
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getModel($1Model.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
In fact, one migration developer already wrote that rule andsubmitted it
for inclusion in the basic set. I will post another upgrade to thebasic
regular expression rule set, look for a "file uploaded" posting.Also,
please consider contributing any additional generic rules that youhave
written for inclusion in the basic set.
Please not, that in some cases (Utility classes in particular)
the rule
application may be more effective as TWO sequention rules ratherthan one
monolithic rule. Again using the example above, it will convert
CSpider.getDataObject("Foo");
To
getModel(FooModel.class);
Now that is the most effective conversion for that code if that
code is in
a page or data object class file. But if that code is in a Utilityclass you
really want:
>
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
So to go from
getModel(FooModel.class);
To
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
You would apply a second rule AND you would ONLY run this rule
against
your utility classes so that you would not otherwise affect yourViewBean
and Model classes which are completely fine with the simplegetModel call.

Subject: [iPlanet-JATO] Use Of models in utility classes
Hi All,
In the present ND project we have lots of utility classes.
These
classes in diffrent directory. Not part of nd pages.
In these classes we access the dataobjects and do themanipulations.
So we access dataobjects directly like
CSpider.getDataObject("do....");
and then execute it.
Since the migration tool does not do much of conversion forthese
utilities we have to do manually.
My question is Can we access the the models in the postmigration
sameway or do we need requestContext?
We have lots of utility classes which are DataObjectintensive. Can
someone suggest a better way to migrate this kind of code.
Thanks

Hi Matt,
Sounds like some of the stuff we need to migrate has a lot in common with
Namburi's project.
I would be very keen to get hold of a copy of the 'tactic' document you
mention below, as well as the sample code you mention to replace CspDBResult
stuff with JDBC results.
Thanks in advance,

I will post a document to the group site this evening which has thedetails
on various tactics of migrating these type of utilities. Essentially, you
either need to convert these utilities to Models themselves or keep the
utilities as is and simply use the
RequestManager.getRequestContext.getModelManager().getModel()
to statically access Models.
For CSpSelect.executeImmediate() I have an example of custom helper method

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.

The hidden field was present in the page, but it looked like this:

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

Re: [iPlanet-JATO] onBeforeRequest(); Finding requested view from requestContext

The problem is that you don't know what the target view is until it has
been forwarded to.
Think about it... the request handling view bean (or command object) has
the request handler that has the code that will ultimately forward to
another view bean. This is code that you have written. So, until that
forwardTo() is invoked, there is no notion of a "target page".
What you do know is which "page" (view bean) the request is coming from
(the handling view bean or command class). You can get this from the
HttpServletRequest. The attribute name is "viewBean".
So you can get the view bean name by doing the following in onBeforeRequest:
<HttpServletRequest>.getAttribute("viewBean");
But I suspect this is not going to solve your current issue.
You could add the target page name to the page session. If there is more
than one possible target page, it might get a little more involved.
Let me know if the use of page session needs further explanation.

Re: [iPlanet-JATO] Re: onBeforeRequest(); Finding requested view from requestContext

If you want to stop a JATO request in its tracks, you have a little black
magic at your disposal: you can throw a CompleteRequestException. This
indicates to the JATO infrastructure that it should immeditately stop
handling the request, but not generate an error, as the develper has taken
full control. You can generally throw this error from anywhere, at any
point--it is a RuntimeException, and is "tunneled" through other exception
handlers where appropriate.
In your scenario, you want to check if the user is logged in, and if not,
save the target URL using the parsePathInfo() method. Then, forward to the
login page and then throw a CompleteRequestException.

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.

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

Re: [iPlanet-JATO] Transaction in JATO

Jeff--
I have one thing to add. You can obtain a JDBC Connection in several ways.
First is to simply use a JNDI lookup on your own, as you would in any J2EE
application. The second it to use JATO's SQLConnectionManager (available in
the RequestContext), which provides some additional convenience by
interposing a level of datasource mapping indirection (see docs). Third,
you can obtain the connection that any given QueryModel would use by
default by calling its "getDefaultConnection()" method. This saves you from
worrying at all about the JDBC datasource name used to obtain the
connection.
Any one of these three techniques is perfectly fine; choose the one that
makes sense for the maintainability of the application in the long run.

The result set that you get back is a JDBC ResultSet, not a "JATO" resultset. In ND, everything was wrapped in a "spider" data

Re: [iPlanet-JATO] Re: Translation hangs tool (retitled Custom Superclasses and warning T008)

Sonal,
I believe that you are misinterpreting the documentation.
I understand that PgCommon has to extend ViewBeanBase. I tried to
make the following changes in PgCommon and compiled it. Then I ran
the extraction which threw up the following error:
I believe that you are confusing extraction issues with translation issues.
The warning message that indicates the need for a class mapping strategy to
address custom superclasses in the original project is a TRANSLATION time
warning.
T008 No mapping found for [<ndClassType>]
Falling back to [Object]. Please add entry for [<ndClassType>] to
class mapping file, restart the toolbox and re-run the translation.
As such, the remedy for this warning is detailed in the documentation under
the heading
Extraction/Translation Error & Warning Messages
3.3 Notes on MigrationClassMappings.properties
It sounds to me that you have misinterpreted the instructions and have
attempted to modify the original PgCommon declaration, and then re-extract.
This is incorrect. This implies that you see this as an extraction tool
situation, which it is not. This is a translation tool consideration, and as
such does not require any adjustment of the original NetDynamics' object. So
please, return to the original PgCommon declaration, and recompile. Then run
the extraction tool. Then run the translation tool, and make note of the
translation tool warnings and deal with them.
As indicated in the documentation (although perhaps not clearly enough), the
solution to warning T008 is not to make your original PgCommon extend
ViewBeanBase, but rather to adjust the MigrationClassMappings.properties so
that the TRANSLATION tool will take your class mappings into account when it
translates the ND objects into JATO objects.
Specifically, if you add the following entry into the
MigrationClassMappings.properties file:
PgCommon PgCommonViewBean
then the translation tool will cause all classes which previously extended
PgCommon to be translated into new classes which now extend
PgCommonViewBean.
Your final step is to adjust PgCommonViewBean's constructor. Note, we are
talking about PgCommonViewBean here (i.e. the output of the Translation
tool, not the original ND object).
Change it from this:
public PgCommonViewBean()
super(PAGE_NAME);
setDefaultDisplayURL(DEFAULT_DISPLAY_URL);
registerChildren();
initialize();
TO THIS
public PgCommonViewBean(String name)
// Adjust the constructor because this is a superclass
// of the other viewbeans. It is NOT a stand along page
// Therefore its constructor should be adjusted to pass the
// page name argument up to the ViewBeanBase class
super(name);
/* Delete the following lines, they are not needed if this is acting as a
superclass of other viewbeans.
setDefaultDisplayURL(DEFAULT_DISPLAY_URL);
registerChildren();
initialize();

Alex,
In addition to Todd saying that the ND security object "is nothing morethan a
sessionable object...", remember that the security object did nothing morethan
retrieve the user profile from some persistent store: a database or athird party
API. So the security object was just a very specialized model (a dataobject in ND
terms, of course), although it need not be a model, it could just be anarbitrary
Java class, whatever works best.
Once the security object was triggered to perform a user profile lookup,the
profile was stored in an instance of CSpUserProfile and kept in the user's
session. The project object was then the object that was responsible forchecking
the user profile for privileges, previous pages, and db logins and such.As Todd
explained, the ViewBean API now does the security check (as opposed toJATO's
module servlet, or ND's project object), so extending ViewBeanBase andoverriding
securityCheck is a convenient way to mimic ND's security hooks. You couldeven
override a method or event in the module servlet to do a lookup if youwant a
greater parallel to ND, but this is unneccessary. Either way, the securitycheck
is performed before the "page" is "loaded".

We're still on the fence. We want to add it, but feel it'll take a fair
bit
of design to do properly and extensibly.
However, realize that the ND security object is nothing more than a
sessionable object with slots for username, password, and priveleges.This
is almost trivially easy to replicate on your own, with a small additionof
code to automatically handle lifecycle and security checking. It wouldbe
extremely easy to create a subclass of ViewBeanBase that would overridethe
securityCheck() method to check the state of a sessioned "user profile"
object. Add to the ViewBean a declared set of "privelege" strings, andyou
can check the profile object against those required.
I feel I'm being unclear--do you see where I'm going?

Hi,
We used a lot of "security object" in netD projects. Each used
username, password and privilege for login. After migration,
we have to hand code all login codes manually. Session control
is pretty standard in j2ee, i'm wondering whether there is a
best practice example available for netD login feature.
Since security was one of the outstanding feature in netD, it will
be a great idea to have a stadard plugin to support this feature

there are several login methods in j2ee.

The iMT has a ND to JATO/J2EE mapping document that covers ND
events and
common ND class/variable/method mapping.
To answer you two questions below:
onSessionTimoutEvent is onSessionTimeout in JATO and can beoverriden in
any class the subclasses JATO'scom.iplanet.jato.ApplicationServletBase.
Typically, this is done in you application servlet class which allof
your module servlets in the application will subclass.
onSecurityCheckFailedEvent is an ND specific event that istriggered
when a Security exception is thrown in ND. In JATO, a
SecurityCheckException is thrown when the default securitychecking in
JATO fails. JATO's default security is to make sure theRequestContext
object is not null. This is done in the ViewBean API. The
onSecurityCheck event in JATO allows you to hook into thisbehavior and
write your own security checking, or hook in a third party API.You can
call super so that you still get the RequextContext null check.
You should create a "non-visual" ViewBean (behavior only) thatoverrides
the onSecurityCheck event, and all other ViewBeans in yourapplication
extend it to inherit this security checking behavior.
You could also hook in the security in your application Servlet by
overriding one of the events in ApplicationServletBase, like
onBeforeRequest.

Hi,
We have the following two events (onSecurityCheckFailedEvent

How do you solve the corresponding issues in j2ee ?
Is there any example available ?

Out of curiosity - How do you modify the memory parameters for
the container's VM ?? I know I should try to do some research but
figured you may already have some insight and willingness to
share.
Please consider this as low priority.It differs by container; I don't remember details of any particular one.

Re: [iPlanet-JATO] Re: using begin childName Display method

Steve,
It sounds like you have your display fields in a container view, and
that container view is inside of a view bean. I haven't tested whether
the fireChildDisplayEvents has a "deep" effect on its container view
children. Meaning that you may have to set fireChildDisplayEvents="true"
for the <jato:containerView> tag instead. If all else fails and you need
to just get it working, you can set the fireDisplayEvents="true" for
each display field tag separately.

Subject: [iPlanet-JATO] using begin<childName>Display method
Content-Transfer-Encoding: 7bit
I want to be able to conditionally show/hide data as well as
format
it for display without touching the model. I found the
begin<childName>Display and end<childName>Display methods that
provide the hooks to do this, but I have been unsuccessful in
getting
these method to execute. I added the
fireChildDisplayEvents="true"
attribute to the jato:useViewBean tag, but this has not helped.
I
also added some debug to the ContainerViewBase class in the
public
boolean beginChildDisplay(ChildDisplayEvent event) method to see
what
was happening. The displayMethodMap was returning null for the
child
display methods that were in the view bean. I covered all the
bases
(compiling, redeploying, etc.) and nothing has worked. Is there
anything I am missing or is there some working example of this?

The hidden field was present in the page, but it looked like this:
<input type="hidden" name="jato.defaultCommand" value=""../search"">
Seems like there is a small bug in the code generating this tag.
FYI - I am using JATO1.2
What file displays this text? Maybe I can go in and fix it and rejar
it.

Can you check the HTML source that shows up in the browser? Do you see an entry that looks like this at the bottom of the form in

To answer your question - it should work as you described. Some of the JatoSample make use of the defaultCommandChild. Can you try
running the sample BasicSample->Field Types and let us know what you
see.

Subject: [iPlanet-JATO] Using the defaultCommandChild in a form
I am trying to set the defaultCommandChild in my jato:form tag to be
the searcg button. The search button definition is:
<jato:button name="search"/>.
The form tag definition is:
<jato:form name="PendingIA" defaultCommandChild="/search">
Clicking on the search button works fine, but hitting return in one
of the textFields (which submits the form) passes a value of "" to
the createChild method in my viewBean, which throws an error. Why
does this not just work as normal and trigger the handleSearchRequest
() method?

Re: [iPlanet-JATO] Submit Button in TiledView

John,
Please clarify,
1. You are putting this page together manually? (writing your own JSP and
ViewBean/TiledView classes?)
2. What is the exact location of the button?
Is it below the TiledView but still in the ViewBean (as the traditional
First/Next/Prev/Last buttons are? )
Or
Is it literally within the tiled view itself (in a column, and the button
is displayed repeatedly like any other row member?)
I ask because the latter is a very rare situation, usually people use HREFs
in such cases?

I have a submit button that appears in a TiledView. When I click

Re: [iPlanet-JATO] .select()

Prashanth,
I assume you are trying to set the default values of the selectables.
Matt,
Actually, I believe this is a view type behavior because it is manipulating the
html properties upon preparing the object for display, however, currently it
appears there is no method for this. For now, you could get the raw html (in
the selectable fields end<fieldName>Display event) and manipulate the html
there. This is not the preferred way obviously, but after combing the API, I
don't see a direct way of doing this.
I'm sure Todd will chime eventually to clear it all up.

Craig,
I see your point. I would think that model holds the value and the view
displays it and may control the model too. I would think that the
setter/getter of what's selected is part of the model. I don't know and I
am sure that after I go to bed Todd will clear it up.
