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.

I guess what I am thinking about doing is capturing the requested URL,
i.e. /appname/modulename/RequestName. In the onBeforeRequest(). I
would then check to see if the user is logged in, and if not, set the
URL in the session(or page session of the Login bean) and forward to
the Login viewbean using the viewbean manager. Inside the login view
in the handleSubmit() method I would authenticate the user and then
get the URL out of the session (or pagesession). I would then
magically get the ViewBean/Command object for the URL or otherwise
"forward the request" as if the user had typed in
/appname/modulename/RequestName, which is the behavior I am trying to
acheive.
It turns out I cannot forward in the onBeforeRequest() as it will
output the viewbean and then continue to process the request which in
turn trys to do a RequestDispatcher().forward after data has been
written to the stream which does not bode well with the servlet
container. Thus, it appears I have no control of the request in the
onBeforeRequest() method. Is this correct?
In light of this new observation I am now going to create a base view
class that all views will extend from and override the
onSecurityCheck() method to forward to my login bean. If I can't find
any other way, I will get the URL from the page session and do a
response.sendRedirect() to the URL.
Thanks for the help!

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.

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[2].tbFieldName" value=""

Now when I say getTbFieldName().getValues() it returns only the first
element values in the object[] and the rest of the

May be we need to create a utility method do get these values from
requestContext.

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

turned off, and it is turned off for the SQL-based models.

Hi,
I wanted to know how the getValues() method works the reason being,
when the tiled view is NOT bound to a model, it populates all the
fields with the same name as some thing like
PageDetail.rDetail[0].tbFieldValue
PageDetail.rDetail[0].tbFieldValue
in which case, the getValues() method works fine.
But in case where the tiled view is bound to a model, it populates
with different field names such as,
PageDetail.rDetail[0].tbFieldValue
PageDetail.rDetail[1].tbFieldValue
in this case, the getValues() doesn't work. Any soultion to this?
We are using Moko 1.1.1.

Re: [iPlanet-JATO] TiledView - getting Values

Kostas--
This is because in TiledViewBase.mapRequestParameters(), calling
getChild(String name, int tile) before setting the values in the request,
will not set the location for the models other that the primary model-
effectively we are only setting one value (more that once if there aremany
values being submitted). So we get the value of the last value in thetiled
view. This is because getChild only changes the location on the primary
model. Which is why I the following code change worked.Ah, I admit I didn't connect the problem to this. Thanks ver much for
clarifying.
As you stated it might be better to add a place holder for all other
auxillary models and keep them in sync with the primary model.Agreed, this sounds like the correct approach. My unstated assumption was
that all location changes to the primary model would also occur on the
auxiliary models, so that would mean that the mapRequestParameters() method
would then work as intended.
How about making the primary model the controlling model. We would have to
"prime" the other models to ensure they all have the same number of rowsas
the highest model for the request. Otherwise we will the followingsituation
I detailed in the prevoius email:That works for me, but it will no doubt result in some strange behavior for
someone down the road. I'll see what's possible about syncing primary and
auxiliary models more explicitly, or at least checking for the situation
where the primary has more rows than the other models.
This way developers would not have to determine if a DisplayField is bound
to non primary model and do additional processing. I suppose it is aslight
design question as well. Enforcing a MVC approach is about going to the to
the Model to get you data. Onthe other hand NetDynamics just allowed youthe
get the value(s) of a field regardless of the Data Object it was or wasn't
bound to.Right, and I think it's important for JATO developers to preserve both techn
iques. The nice thing the technique of accessing the fields directly gives
you is the ability to obtain data in a non-model-specific way. This can be
just as valuable as providing model-only interactions.
Thanks for your feedback Todd. Let me know what you think.Same to you. I hope others on the list have similar suggestions that they
share with us. I think the above approach is sound and I'll be putting it in
for the next patch version, 1.1.2. If anyone has any final comments, please
let me know ASAP.

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?

Since security was one of the outstanding feature in netD, it will

Subject: Re: [iPlanet-JATO] onSecurityCheckFailedEvent & &

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.

Chidu,
I think that you are mired in the very common confusion of the default
behavior of the ApplicationServletBase.parsePathInfo() which will determine
the controlling/handling ViewBean via a URL design pattern. Lets take a look
at the URL
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.jsp
is decomposed as follows:
/NASApp -> well, this is long story but is absolutely necessary, welcome to
iAS
/MigtoolboxSampleAppWar -> is the web application name, taken as the name of
the WAR file when there is no EAR file (this allows the Servlet/JSP
container to deferences the web application root under
<ias>/APPS/modules/MigtoolboxSampleAppWar) I think this part of the URL is
called th Context Path
/MigtoolboxSample -> is the Servlet Path, and will either directly reference
or match a Servlet Mapping
for instance
<servlet-mapping>
<servlet-name>MigtoolboxSampleServlet</servlet-name>
<url-pattern>/MigtoolboxSample/*</url-pattern>
</servlet-mapping>
tells the Servlet Container that the Servlet Path
/MigtoolboxSample
maps to the Module Servlet MigtoolboxSampleServlet
This is how EVERY request makes its way to the "front controller" pattern in
JATO. It is fundamental to JATO Applicatioan that every request pass
through the ModuleServlet.
every else on the URL past the Servlet Path is the PATH INFO. Based on this
understanding, you will see why the
ApplicationServletBase.parsePathInfo()
is so important. In parsePathInfo() the PATH INFO is compared to the design
pattern
/VIEWBEANNAME*
to determine the handling ViewBean from the first String Token in the path
info. For instance, the starting URL of the Sample Application is
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage
The PATH INFO is [IndexPage]
and IndexPage[ViewBean] is the handling ViewBean. Therefore, any simiarl
URL like
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.jsp
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.matt
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.mike
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.chidu
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.XXX
will all result in the same handling View Bean
IndexPageViewBean
It is very important to understand that you CANNOT hit the JATO JSPs
directly. You must hit the "front controller" ModuleServlet which will
always delegate control to the handling ViewBean (a la, the "service to
workers" pattern)
You can attempt to hit the JSP directly but you need the right J2EE URL
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSampleApp/MigtoolboxSample/IndexPag
e.jsp
this URL will directly hit the JSP. However, you will recieve an error
because the JATO framework quickly determines that there is no
RequestContext in the HttpRequest attributes and assumes that the "front
controller" was bypassed. Try it. You will get ERROR.
Lets go back to what you are trying to do, place Models and Viewbeans in
separate directories. I recommend that you move the Models. Models are
ONLY referenced by TYPE via the ModelManager, the compiler will ensure that
your code is correct and matches the packages, file locations, import
statements, etc. ViewBeans, on the other hand are related to the
ModuleServlet their are contained in and are loaded via type names according
to a design pattern.
if you want to separate models and Viewbean then simply move the Model and
make sure everything compiles.
you cannot move the ViewBeans
if you do want to move the JSP peers of the Viewbeans, then you can put them
anywhere in the web application doc root. When you do, update the
DEFAULT_DISPLAY_URL as Mike suggested

Chidu,
Did you have it running fine in the original default configuration, before
you started changing things around? The URL should not access the .jsp
directly. The URL should look more like this
"/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage", without the
.jsp.
Also, please read the "Migration Tech Notes" document that is

RE: [iPlanet-JATO] image button handling

Hi Todd,
from what I have seen so far on the Project they are just buttons on
the page.
In the interim, I modified RequestHandlingViewBase.acceptsRequest() to
handle the matching of parameter and command child names.
from
if (request.getParameter(commands)!=null)
return getCommandChildNames()[i];
to
if (request.getParameter(commands[i])!=null ||
(request.getParameter(commands[i]+ ".x")!=null ))
return getCommandChildNames()[i];
This fixed the problem with the image buttons in our cases.

Hi Kostas--
I wanted to get some feedback on the known issue of the
handleXXXXRequest method not being fired for buttons which have
images, due to the the browser submitting
the pixel coordinates back to the server like this:
Page1.ImageButton1.x=...
Page1.ImageButton1.y=...
As the ND conversion project we are currently working on heavily uses
image buttons we would like to get and indication if and when a patch
is planned for this.
Our current work around is to remove the src attribute from the JATO
tags in the JSPs.We are currently working on getting this fixed. One question--what is
the
relative type of usage of image buttons in your project? Are they just
buttons on the page (view bean), or do they appear in tiled views as
well?

OK, here's what I'm trying to do: We have, like you said, a menu
page. The pages that it goes to and the number of links are all
variable and read from the database. In NetD we were able to create
URLs in the form
pgXYZ?SPIDERSESSION=abcd
so this is what I'm trying to replicate here. So the URL that works
is
pgContactUs?GXHC_GX_jst=fc7b7e61662d6164&GXHC_gx_session_id_=cc9c6dfa5
601afa7
which I interpreted to be the equivalent of the old Netd way. Our
javascript also loads other frames of the page in the same manner.
And I believe the URL-rewritten frame sources of a frameset look like
this too.
This all worked except for the timeout problem. In theory we could
rewrite all URLs to go to a handler, but that would be...
inconvenient.

Hi,
We observed the following difference in behaviour between JATO pages
and NetD served pages.
We have the following scenario. User will login to the
site. After login he will get a frame set. This frame set has threeframes.
Top and bottom frames are used for navigation (to switch between various
sections on the site.) .The middle frame(main frame) shows the actual
content. When the the frame set gets loaded main frame shows page1. User
will click on a link on page1. Page 2 will be loaded in main frame. Atthis
point if the user clicks on back button , with migrated application(JATO
pages) the following message appears in the main frame.
In Netscape Communicator 4.61 the following message appears in the main
frame :
Data Missing
This document resulted from a POST operation and has expired fromcache.If
you wish you can repost the form data to recreate the document by
presenting the reload button.
In IE 4.72/5.5 the following message appears in the main frame:
Warning : Page has Expired
The page you requested was created using information you submitted in a
form.This page is no longer available.As a security precaution, Internet
Explorer does not automatically resubmit your information for you. To
resubmit your information and view the web page click teh refresh button.
However, in the NetD site page1 will appear in main frame.
How do we mimic the NetD behaviour with the migrated
applications ?
We think the above behaviour with migrated Apps, is due to the
headers that are get set in Application ServletBase , see the following
code snippet :
protected void addResponseHeaders(RequestContext requestContext)
// These values should make any proxy between the client and
// server avoid caching, and ensure that pages from one user
// can never be seen by another user (if they're cached anyway)
requestContext.getResponse().addHeader("Pragma","no-cache");
requestContext.getResponse().addHeader
("Cache-Control","private");
If we comment the above code , we were able to mimic theNetD
behaviour. Are there any alternatives/thoughts on how to mimic the NetD
behaviour ?
Thanks in Advance,
syam&ravi.

I am experiencing a problem while executing a bounded model. I am usingQueryModelBase. Whenever the following query gets executed inonBeforeModel

of data. Please could you tell us how the mapping between model and

you provide in your model's column descriptors. It sounds as if you are

I'm sorry, this isn't enough information for me to offer any suggestions.
Using the technique above, determine which columns are coming back in the

those column names. The problem could be something as simple as a typo in
the field's bound name, or something more complex like the column in the
result set being named something you don't expect.
Another approach might be to alias the columns yourself using the "AS
