UIX XML samples

I found a freely accessible link, that says something about a demobundle for UIX:
http://otn.oracle.com/sample_code/products/jdev/uix/demobundle.html
however I can't download these samples.
Are there ANY samples available for UIX XML at all??
I think samples are absolutely necessary for a framework as complex as UIX.

Has anyone made a UIX-XML Sample?

Has anyone sucessfully made an oerational UIX-XML sample using scott's schema?
Can you email it to me.
I've tried but it fails with some array out of bounds error on all forms except main.xml.
TIA,
Ed.

Hi Ed,
I've never used the "scott's schema" however I have used the wizards to create a UIX/XML BC4J test application using the "HR" schema (employees and departments) in the Oracle 9i DB.
I can email it to you if you provide your email address.
Regarding ">I've tried but it fails with some array out of bounds error on all forms except main.xml."
I've seen that error and in my case it was caused when I used the UIX/XML BC4J wizard generated app that contained * intermedia * datatypes.

Sample UIX XML requested for standard functionality

I am learning UIX XML.
Using scott's emp and dept tables, I have used the wizards to generate a UIX XML application using BC4J.
I would like to enhance the generated UIX XML.
For example...
1. The UIX XML pages that allow inserts/updates to the EMP view object. I would like to have a LOV on the dept_no field so user can use this. Typically any foreign key field to have a LOV with a lookup on the master table.
2. Also I am having some difficulty with radio groups, list items etc that are based on hardcoded values or data in the database. Have you any complete example code. The on-line documentation shows examples but not the whole code working together. Have you got a complete sample app that shows these features?
3. Have you any UIX XML examples that use FORMS containing text input items, lists, radio groups etc that ARE NOT based on BC4J...then have the event logic access BC4J and do the inserts/updates.
Thanks,
Paul.

Paul,
Like you I have been learing using the scott schema.
I too have struggled with this LOV issue in UIX-XML and UIX-JSP and BC4J-JSP. UIX-JSP can allow for a drop down list based upon custom properties in the VO and a "custom" Java class. The HOW-TO Page has an excellent example that when followed (with some tweaks to get what I wanted) the drop down list worked. I know it's not an LOV (like in Forms) but for small FK lookups drop down lists seem to be the requests of most users. But these drop down lists will not happen in UIX-XML or BC4J-JSP. Seems aierd to me but hey, I'm just learning too.
My point is that I too have asked question after question on this forum about UIX-XML or about implementing fearures of UIX-XML in other frameworks (like coulmn sorting) and have gotten zero helpful repsonses. There were some comments about how 9.0.3 would soleve some of these issues, but no one seems to be able to explain a way to show a "broken" example so that I will be elated when 9.0.3 comes out and works.
If you get an answer or some helpful pointers pelase forward them to me at [email protected]
And I apologize for making your heart get all a flutter when you saw the reply count grow by "1" only to find that it's just another loser who can't make the simple things in this IDE work.

UIX-XML

Hello everyone,
I'm fairly new to UIX-XML and I have several questions about it.
First:
I am creating a test project to try out UIX-XML. I wanted to place all the UIX files in a subdirectory within public html. When I try to run the application, the container claims that it can't find the file. But when I put the UIX files directly in public html, it runs fine. Isn't it possible to put UIX files in a subdirectory within public html?
Second:
After studying the tutorial about UIX-XML I know that you can create UIX-XML output just with java code. I assume that all the code should be placed in .java file. My problem is how I can use it to get the output of the .java file. Should I just create a JSP page and implement the .java file or is there another way?
third:
Can someone give me some good resources for more information about UIX-XML? I am having troubles to find good documentation about it.
Can someone please help me with these problems?
thanks a lot.
john

First:
I am creating a test project to try out UIX-XML. I wanted to place all the UIX files in a subdirectory within public html. When I try to run the application, the container claims that it can't find the file. But when I put the UIX files directly in public html, it runs fine. Isn't it possible to put UIX files in a subdirectory within public html? Which version of JDEV are you using? I had no trouble putting a uix file in a sub directory under public html and running
in either 902 or 903 preview.
Second:
After studying the tutorial about UIX-XML I know that you can create UIX-XML output just with java code. I assume that all the code should be placed in .java file. My problem is how I can use it to get the output of the .java file. Should I just create a JSP page and implement the .java file or is there another way?I am a little confused by your question. I think you mean how do you create a UINode tree and then render it to html.
Is that what you mean? Have you read the UIX Developer's Guide in the JDev help? There is a section
in UIX Basics about creating pages in uix that you might want to read.
third:
Can someone give me some good resources for more information about UIX-XML? I am having troubles to find good documentation about it.Again the best source of information is the UIX Developer's guide and reference in the help topics. Hopefully soon
we will post some jdev sample projects with some demos that we have internally.

Help by date format in UIX/XML

In UIX/XML I would like to indicate the date fields in the format to 'DD.MM.YYYY '. I modify the properties of my view object and entity object in the window "structure window". It does not change view for anything.
What wrong do I make?
Who can help me please !!!!

Please post what version of JDeveloper you are using. Also post a small sample application that shows what you are trying to do.
I am not sure what you mean. Are you trying to display a date from the database, or have the user enter a date?
The date format is determined from the client browser locale. It will default to the US date format mm/dd/yy unless the browser locale is overridden.
If you want the user to enter a date, you should be using <dateField>. This will also expect mm/dd/yy unless you override it with a validater. Please refer to the UIX Element Reference. This documents <dateField>. The <onSubmitValidater> is a child of <dateField>, it is also documented in the Element Reference. <date> is the validater you want, it is a child of <onSubmitValidater>. You can specify a validation pattern.

Jdev Team - Frustrated with Simple UIX-XML test case

Why can't I get a simple UIX-XML test case to run? Better still why can't I get a response as to why it won't run? This is my second attempt at a post as the other was just left hanging. Iwas asked for more info, I provided it and that ended that.
Again, I created a workspace. Used the scott schema and created a project with a set of VO's (and took the ALL defaults). I have created a UIX-JSP and BC4J-JSP projects that both run fine (taking all the defaults). In that same workspace without any modifications to the VO's I created a UIX-XML project. The main menu runs fine. None of the forms will run. I get the following error if I choose ANY form from the menu or I get the same error if I just run any form from Jdeveloper (except main.uix of course):
Servlet error: Renderer failed: java.lang.ArrayIndexOutOfBoundsException: -10
What is happening? Why cant I get this to run. Is this a failed technology? I can't seem to find any working UIX samples.
TIA,
Ed.
PS. A footnote: * It seems if you don't get an answer from the Jdev team inside of two days your post is toast (unless it's a rant in which case everyone seems to jump on the band wagon). :-) :-) :-) ;-)

Hmmmmm...... did I mention I was on Internet Explorer 6.0.2600.0000 ? Probably does not matter.
Also, although I loaded the full 9i Developer suite, I also loaded (in a seperate directory), Sun's J2DKSE 1.3.1_03 and J2DKEE 1.3.1 and have the following local environment variables set:
JAVA_HOME = d:\java\j2sdk
JDK_HOME = d:\java\j2sdk
J2EE_HOME = d:\java\j2sdkee
JDEV_HOME = d:\oracle\9iDS\jdev
Are any of these redundant or are they clobbering something for UIX-XML?
TIA,
Ed.

UIX XML & Download Of Uploaded Files.txt

What is the right way (in UIX XML) to show the content of an uploaded file (retrieving it from a BC4J component)?
Documentation, Samples?

your question is rather vague; are you asking how to handle a fileUpload using the UIX controller? Please see the javaDoc for the class
oracle.cabo.servlet.AbstractPageBroker

UIX XML test did not work

I created a sample project based on the Scott Schema for BC4J Business Objects.
I then created sample projects for:
BC4J JSP
UIX JSP
UIX XML
When I run the BC4J LSP and UIX JSP projects the main menus open and I can browse, edit and update all of the scott tables.
However when I run the UIX XML project, the main menu comes up but if I select ANY view to work with I get the following error.
Servlet error: Renderer failed: java.lang.ArrayIndexOutOfBoundsException: -10
What coulbe wrong?

To confirm, you say that the files generated okay, and you were able
to run Main.uix and see it in your browser correctly, but clicking on the
link to the view object generated a Renderer failed exception in the browser.
Is this correct?
What customizations have you made to your View object (or is it simply
as the wizard generated it)? Can you look at the log window in jdev
(or your OC4J servlet log) to see if there is additional debugging
information available? Yes the files generated and compiled ok. I can see the main menu in my browser.
The UIX-XML project was created using the wizard generated VO's. No customizations were made at all.
The Embedded OC4J Server messages window in Jdev shows no errors. The Messages window shows no errors.
FYI, this is on an NT machine that has the full install of Jdeveloper9iDS (Jdev, Forms 9i, Designer, SCM etc.) not just Jdev9i. I'd hope this does not matter but thought I'd mention it. No other Jdev windows (Forms 9i etc.) are up when I run this test.
TIA,
Ed.

UIX/XML and BC4J -- practical???

Has anyone actually used UIX/XML and BC4J to develop a "real" application? The majority of the examples in the help screens use jsp's, yet the comparisons I've read in the help screens seem to indicate that XML is more flexible.
UIX/XML seems like such a clever concept, I like the idea, but it's getting the best of me. Should I jump ship now?
Any comments please!
js

Examples are definitely what's needed and I put my request for a full blown MVC application using UIX/XML (without BC4J in my case) to Adam a while ago which was forwarded to the 'management'. Hopefully something will come from this soon. I agree with Janet that UIX is a great concept (don't jump ship yet!) and it should save us so much work but that real world examples would surely help us all. No disrespect, Juan, but you regularly respond to people's questions with 'Have you read the UIX developer's guide provided in the documentation' - we've all read the documentation many times, if only it were that simple! I'm sure it's easier for someone inside Oracle to get the answers they need whereas we on the 'outside' have to rely on this forum for now which is a struggle.
Bill's idea of illustrations would be great, though I'd like to see the examples relate to the sample screens show on the BLAF standards website. I only found out about the BLAF website accidentally through this forum. The UIX Developer's Guide should explicity reference this as I've found it extremely useful.
Ed,
The UIX Developer's Guide is in the JDeveloper Help.

UIX/XML - BC4J - " a strategic decision"

I have read that you (Oracle JDev Team) suggest using, for new applications, UIX/XML and BC4J.
We are engaging our best resources trying to use these frameworks but, due to poor documentation/samples, we are in serious difficulties.
Every day some new problems rise.
What do you suggest?
- To wait for release 9.0.3 hoping to see a better product and well documented?
- To participate to training courses hoping to find them in our country (Rome - Italy)?
- To continue to solve a problem every day with your help hoping that they are a reasonable number?
Excuse my poor English.
TIA

- To wait for release 9.0.3 hoping to see a better product and well documented?That's a tough one to answer: it depends on where you are in the development
cycle, your schedule etc. 9.0.3 will definitely be an improvement - and these
aren't technologies that will be going away, so there'll be ongoing improvements
in the future.
- To participate to training courses hoping to find them in our country (Rome - Italy)?I wouldn't personally know if those are available. Sorry. :(
- To continue to solve a problem every day with your help hoping that they are a
reasonable number?We'll continue to help! If you're running into problems because of inadequacies
on our documentation, that's our fault, not yours. The questions here on OTN
have been essential in figuring out the most significant holes in BC4J UIX XML,
and I'm sure they'll continue to be.
Excuse my poor English.Your English is pretty darn good. No apologies needed!

How can I render an active link (yrl) within a UIX/XML page

How can I render an active link (url) within a UIX/XML page.
How can I get <jbo:ShowValue> to work in UIX/XML, or is there another way?
Bill G...

It may seem strange, but the <contents> of <rawText> aren't actually
raw - it's only the "text" attribute that's raw. (It seems strange because
it is. Ah well.) This is different from UIX JSP.
So, try something like the following:
<bc4j:attrScope name="Notes">
<contents>
<rawText text="<a href=""/>
<rawText>
<boundAttribute name="text">
<bc4j:attrProperty name="value"/>
</boundAttribute>
</rawText text="">"/>
Some text in the link.
<rawText text="</a>"/>
</contents>
<bc4j:attrScope>
Thankfully, this will be much simpler in 9.0.3, when the following
will work:
<link text="Whatever you want">
<boundAttribute name="destination">
<bc4j:attrValue name="Notes"/>
</boundAttribute>
</link>

How to set system date as a default value in UIX/XML page?

Example: We set default values using following statements:
<set property="inputValue" target="${bindings.PoNumber}" value="${'1234'}"/>
<set property="inputValue" target="${bindings.UserName}" value="${param.MyParam1}"/>
In JDeveloper Help, we cannot find a way to set a Date attribute's default value to today's (system) date. Any suggestions?
Also, does anyone have a reccomendation on a good book for uix/xml?
Thanks, Ali.

Jdev10.1.3: Create an UIX XML Page; Problem: No UIX-Item available...

hello, i am new to jdev. at the moment i'm trying to complete the tutorial "Developing Applications with Oracle ADF UIX". (http://www.oracle.com/technology/obe/obe9051jdev/uixTutorial/lesson_UIX.htm)
my problem: i followed the instructions until i was told, to create an uix-xml page. the picture in the tutorial indicates that there should be an available adf-uix item, but in my jdev there isn't. i know, the tutorial is using an older version of jdeveloper but at least, there should be something similar to the adf-uix item in my jdev.
i thought there is no need in installing some sort of uix files... or am i wrong?

Hi,
Oracle recommends JSF instead of UIX for new projects. If you want to use UIX, take JDeveloper 10.1.2 or 10.1.2.1 instead of 10.1.3.

Georg

UIX-XML BC4J - Unexpected errors using paths and DeltaTree on a particular UIX page

We are using a PageDescription to dynamically change a UIX tree using the DeltaTree technique described in the Dynamic Structure for For UIX Pages chapter of the UIX Developers Guide.

This usage of nested view object scopes has been explained in reply of a previous post, How to databind the children of a UIX XML choice, and before ours attempts to modify the tree it worked fine. Removing the nested view object scope the page makes the page render correctly, but we need it to retrieve the description of its state.
We get the same behaviour (and a much similar stack trace, with the same oracle.cabo.ui.data.DataObjectList oracle.cabo.ui.collection.DataObjectListNodeList.getDataObjectList (oracle.cabo.ui.RenderingContext) throwing a NullPointerException) if we use NodeUtils.createPreorderDescendentAttributeEnumeration method instead of PathUtils.

It's a bug in the DataObjectListNodeList class that's up at the top of
the stack. It's been fixed for 9.0.3. The bit of XML that's triggering
it isn't the <viewObjectScope>s, but the "data:childData".
I believe you can workaround this bug by not passing a null RenderingContext to
findPathWithNodeID(). Now, you don't have a real RenderingContext, and we
don't especially need one - "null" is legit here, but I think if
you just pass "new oracle.cabo.ui.RootRenderingContext()" then you'll
get around this bug.

Uix-xml translated in java

Hi everyone,
I am having a little problem to code uix-xml in normal javacodes. I can built a normal tree with javacode and render it in a jsp file. Now I am trying to translate this:
<ui:cellFormat>
<ui:contents>
<ui:include ctrl:node="defaultLayout" /> (defaultLayout is another uix file)
</ui:contents>
</ui:cellFormat>
According to the tutorial and the javadocs, this should work:
cellNode.setIndexedNodeList( new IncludeUINodeList() );
IncludeBean include = new IncludeBean ();
cellNode.addIndexedChild (include);
But the includeBean still doesn't know that he should include "defaultLayout". Can someone please tell me how I can tell the includeBean, what to include? I really need a simple and precise example, please.....
thx.
John

Try calling IncludeBean.setNode() to set the UINode to be "included".
