Search/Query Form bc4j-uix-jsp

Hi:
Are there any samples of Search/Query jsps using
bc4j -uix jsps?
There are some on OTN using html.
I want to set up a search page that users can select one or more(AND) from about 5 attributes
of a view and then display approx 6-8 different attributes of that same view.
Any input would be appreciated.
Thanks.

Once you create the Query-by-Form datawebbean, you can modify the templates in the templates\webapp directory by changing all usages of the FindForm bean to use your new DWB. You can also create a new webapp template by copying the existing file and creating a new directory. You can add you new template by modifying the templates\apptemplates.xml. The current entries are:
<?xml version="1.0"?>

Master-Detail in UIX-JSP

Hi:
How can i do a master-detail in UIX-JSP similar in functionality BC4J-JSP?. I haven't found an HOW-TO or guide.
Thanks
Marco

Yes this is easily done.
If you have a BC4J project with say Emp and Dept View Objects which are linked via
a foreign key (there should be a BC4J FKDeptnoLink created), then all you have to do
is generate a BC4J UIX JSP application.
In a separate empty project, open the New gallery and select UIX-JSP -> Business Components JSP Application.
Generate a default JSP application for your BC4J components. You can then run main.jsp
to see the app.
To see a master detail view of your app which is based on the Bc4J Link (FKDeptno) just click
on link "FkDeptnoLink" on the left side..

It may be caused by that your browser lauched before the OC4J server initialized.
You can wait a moment till the OC4J server initialized then lauch your browser again.

UIX-JSP vs. BC4J-JSP wizard based question

In BC4J-UIX wizard based forms there exists a button to Insert new rows. In the UIX-JSP wizard based forms there is not. Is this an option I overlooked somewhere or does this need to be hand coded? Detailed instructions on how to implemnt the Insert row capability in UIX-JSP are appreciated.

Ed. Ed -
I'm a bit confused by your reference to the BC4J-UIX and UIX-JSP wizards. There is a 'new' link in wizard-generated
BC4J JSPs and a 'Create' button in wizard-generated UIX JSP browse/edit forms. Is this what you mean?

JDev9i: BC4J JSP or UIX JSP?

Hi,
To develop a large JSP application, I read the document to
decide which one to use BC4J JSP or UIX JSP? but still not sure
which one to start. Any command from experienced JSP developer
would be a great help for me. Thanks.

Hello,
Did you look at the section titled "Which Technology Should I
Use?" in the JDeveloper online documentation? It gives a fairly
decent idea on what you can do with the various pieces if
technology that form a part of the UIX framework. Given that you
are planning on building a huge application I am assuming that
you would be interested in a consistent look and feel across the
different pages of your application. UIX lends itself very well
to build such applications very easily. On the other hand if you
wanted to use JSPs, you could still use the UIX JSP tags which
provide JSP tags which are wrappers for the underlying UIX
elements. However, the UIX elements are much richer in terms of
functionality (attributes, etc.)
Hope this helps,

ADF Search form inside a jsp page's panel page container

I am going through the Oracle JDeveloper 10g for Forms & PL/SQL book and I got to page 391 where I need to drop a search form onto a jsp page set up with a panelpage. The form show up but when I go to delete the extra fields JDeveloper completely locks up. I am running JDeveloper version 10.1.3.3.0.4157. I tried reinstalling it and it still locks up. I tried going back a few steps and recreate the search form and it still locks up.
Can anyone explain why it is locking up or how to delete the extra fields without locking up?

I also tried selecting a field in the source file code window. Just selecting a field in any form or window locks up JDeveloper. My program worked find until I created a search form from a data set. I think it is a bug in the version of JDeveloper I have. I did a similar task in a previous version and it worked fine. I could select and delete fields with no problem.

Bc4j, struts and query form (where)

I have a query form on 1 table created by the wizards (bc4j - struts).
For ex. in the name field I can insert 'Dimi' and the query form will find my record.
But when somebody inserts 'dimi' (not initcap), he doesn't find my record.
How can I adapt the default where clause in the query like eg. WHERE UPPER(FIRSTNAME)=document.form.field.toUpperCase(); ??
In the next release this should be more simple!

You can call setUpperColumns(true) on any instance of your view criteria row that you want to apply this UPPER() function to.
Do you have a functional index at the database level on the UPPER(FIRSTNAME) function?
If not, the query will do a full table scan with the UPPER(FIRSTNAME) in there.

Which Web Client Framework? BC4J-JSP, UIX-JSP, UIX-XML, etc

Trying to determine which, if any of the JDeveloper frameworks, to use for do web browser (HTML) clients.
What are the pros/cons of BC4J-JSP, UIX-JSP, UIX-XML, etc?
What are some common things you might rule out using one or more of the frameworks?
I plan to be using BC4J, updating, inserting data (currently MS-SQL) and the apps will run on WebLogic 7 or Caucho Resin (webapps no EJB) in a cluster. I would like to be as RAD as possible and still be able to do what I need to do. One main concern is being able to add custom HTML/JavaScript for things like client side validation. I didn't see a way to do this when doing BC4J-JSP. Is that right?
If I define any validation in the BC4J, will UIX utilized any of this to define a JavaScript validator or must it be redudantly defined?
One other concern is what the framework requires in terms of architecture, like do I have to have sticky sessions in my web cluster or can it work fine stateless or stateful?
For UIX-XML, how is this architected for performance? Specifically, is the XML effectively compiled and converted into something more efficient and performant or does it do XML parsing all the time? Is there any significant performance differences between the frameworks?
Is there any significant difference in dealing with security? Anything in the framework to make it easier to handle certain users being able to see/edit different set of data?
I have things like some groups can edit only certain entities (product info but not pricing), others only certain types of products (possibly subclass entities) and others situations where what fields than can edit varies. Obviously I can handle this programmatically, but I was wondering what the frameworks had to offer, especially in terms of having different views of the same data.

...I am little confused then about how BC4J works and what is meant by "session" here.
When you talk about appmodules in the plural, does this mean that there are potentially multiple instances of the same data on a single server or there is a common datastore with pending data and client specific stuff varying?
The common datastore is the database. Each client (momentarily, during the span of their request) uses an instance of an application module from the pool. The pool can grow and shrink with load on your system and all of the various tuning parameters. Our doc on the AM Pool covers all the parameter settings and their users.
What kind of "session" is this?
It is an abstract notion of a session for a user. The implementation used for Web clients uses the HTTP Session Key as the session key. However, we have other session implementations (and you can provide your own to do custom stuff for more sophisticated needs). We don't store anything else in the HTTP Session to the best of my knowledge. This way in a cluster, the web container doesn't have to waste time propagating all of your serialized HTTP Session state among cluster members. This session key also include an id for the application module and together those provide the key to store your pending state in the database for the "Stateful == Managed State" feature.
I assume that if I have a cluster which doesn't use session-to-same-server-affinity but uses JDBC for http-session persistance or distributed in-memory http-sessions then I cannot use stateful BC4J even though I can use http-sessions.
You can use BC4J in this way because the browser will send a cookie that contains the key to your database-stored pending state. In this way, we work great in a server farm for failover and/or scalability reasons.
Even if I use stateless BC4J, are there issues with round-robin'ng all requests to different servers in a cluster?
As I said, both our Stateless and Stateful features are designed to be used in Server farms, no problem.
BTW I wouldn't necessarily say you picked the wrongs terms for the modes, but I know what you mean. There's problems with these terms. I am trying to explain to my mgrs/engineers that there is some state in stateless transactions - that simply making everything "stateless" doesn't mean don't lose anything in a disastrous failure. I am arguing to get support for sessions in our cluster, that the performance gain and simplified development is worth it as long as you put intelligent limits on what you store in the session. Right now, they are insisting on randomly sending requests into two entirely different data centers, with two different clusters.
Amen. I have seen too many developers make the mistake of trying to be totally stateless, only to completely complicate their development environment with having to peristent partially-completed transaction data to the database. I've seen this done with sets of "Shadow" tables (yuck!) or using hand-written techniques similar to what BC4J provides a robust implementation of in the box.
We've tuned our "Stateless With Affinity for Server Farms" model over several releases of carefully studying the performance of the Web apps built by our internal Oracle Applications teams using BC4J (over 20 of them now, and growing!) so compared with a hand-written strategy for your web-tier state management, using BC4J's implementation will be much more productive for you.
We're tuning and tweaking and enhancing it even more for the 9.0.3 release as new needs are highlighted with continued use by our customers (both Oracle internal and external).

HTML Rendering works on UIX-JSP but not UIX-XML or BC4J-JSP

I built a "custom" renderer following the HOW TO document for HTML rendering. I made a "Drop Down" list that works in a test UIX-JSP application. When I try to attach the DynamicListInputField class to a project created under UIX-XML or BC4-JSP the rendereing does not take affect. No errors, the application runs fine, just no rendereing.
I made all three projects from the same VO's and the same DynamicListInputField.java. The three projects were Wizard Based and created with:
"Business Componets UIX XML Application" from the UIX XML Category
"Business Componets JSP Application" from the UIX JSP Category
"Business Componets JSP Application" from the BC4J JSP Category
What is wrong?
TIA,

What error you are getting...please provide error details.
It is working fine for me.

How to use ShowValue within a UIX/JSP page to display an active link?

I am storing URL's in the DB and want to display them as active links on a UIX/JSP page. I thought that I had this working some time ago, but now it no longer works.
Using <bc4juix:RenderValue datasource="ds1" dataitem="myTextField" /> will display "http://www.otn.oracle.com" as an inactive link using UIX/XML which is expected.
Using <jbo:ShowValue datasource="ds1" dataitem="myTextField" /> will display an active link using if using BC4J/JSP, which is expected.
However, I have not been able to do this using a UIX/JSP page.
Is it possible to use ShowValue within a UIX/JSP page to display an active link?

Reduce the size of Input box comingby default with search query

Hi,
I have created one EO and VO and one jsp for that . Inside that VO , there is one option Named Criteria, which is having All Queriable Attributes option , on drag and drop of this option i have got default search page for all the attributes which i had in my form , But with every dropdown am getting one input box to specify the value of my search, i want to reduce the size of that input box . there is no code in the jsp for those attributes.
Please help

Filed bug# 6501297 to track this issue. Thanks for reporting it.
For now you'll need to manually add an additional facet to the content of the query component's "valueStamp" facet with the id of the same name as the attribute and manually set the properties on an <af:inputText> to the desired width.
Between Tech Preview 2 and production the Query form component is being simplified to be more metadata driven, so this temporary workaround is applicable only to the TP2 release.

Query form requires Logical operators and/or Quotes

In ORACLE 9I Jdeveloper beta I used the BC4J JSP wizard to create a - Query Form. The query form looks nice and runs except I have to also include the logical operators (= > <) and Quotes. For example to query on the name Joe I have to enter it as ="JOE". If I use JOE it gives me a JSP error. The error message shows the generated Select statment with the where clause JOE but is missing the "=" and quotes.
How do I hard code the "=" and quotes around strings so that the user doesn't have to?
