LOV Databinding on ADF Struts

Dear All..
I want to migrate my report application from Oracle report into Java with ADF and struts.
my report application on oracle report I made the parameter to display the data using these query
select a.Salesno, a.salesdate, a.prodcode, b.prodname, a.qty
from sales a, products b
where
a.prodcode = b.prodcode
and
a.sales date between :p_date1 and :p_date2
and
a.prodcode between :p_prod1 and :p_prod2
while P_date1, P_date2, P_prod1 and p_prod2 are the
parameter to display data. the parameter itself using
the combo box.
How to make these simple things on ADF struts using LOV data binding with step by step configuration..
Hope anyone can help me to learn about these...
thanks you

Erie,
have a look at the Jdeveloper website (otn.oracle.com/products/jdev). There are howto documents written that explain the use of LOVs.

How to use ActionForm validate() method in ADF/Struts project

Hi
We are developing a project using ADF/Struts. We are not planning to use entity level validation. Rather we prefer to have it at Struts Form Bean level. So we need to have validate() method in Form Bean.
That mean we need to have seperate bean for all the actions /jsp. The ADF's DataForm form bean is not gonna work for us. Is that correct.
Please let me know...am I in the right direction.
That could be a different discussion why we don't prefer entity level validation

You can use the Struts validator plug-in (there's a howto on doing that on OTN) and it will handle the basics for you through XML definitions.
If you want to specifically have a Form bean with a Validate() then the issue is that the current "DataForm" is a generic bean driven of the databinding files, so yes you'd have to write a bean per screen to use instead and loose that benefit of having a universal Bean. (Internally the DataPage and DataActions will respect the ActionForm APIs so you can pluf your own ActionForm subclass in with no problem.
Plan B might be to leave the DataForm Bean in place and instead override the lifecycle of the datapage, probably in prepareModelUpdates()

Help with simple display and add in ADF/Struts app

I created a simple ADF/Struts application based on the HR schema. I have a department view object and entity object based on the Departments table. From the Struts page flow designer, I create a data page action (viewDepartments) that binded to a departments view object by dragging the departments view object as a "Read-Only" form from the palette with the navigation buttons --- this page will just display the departments. Next, I created another data page action (addDepartments) that allows a user to add a department. I did this by dragging the departments view object from the palette as an "Input Form" and then dragging the "Create" operation onto the data page action. Each data page action has its own JSP of course.
I'm noticing that every time when I go to to the "addDepartments.do" and then go to "viewDepartments.do", a blank record is added to the view object. Why is this? Also, I want the Submit button to do the "save and commit" in one step. How do I do that?
If it helps, I can email anybody the workspace file so that you can see this behavior.
Thanks.

Adf-Struts/JSP/BC4J- and setting date fields from jsp

Hi,
I'm working with the new ADF Frameworks (JDev 9.0.5.1) and ran into some questions regarding exception handling using BC4J, Struts and JSPs.
I have a DATE column in database and an entity and VO with a datefield with type oracle.jbo.domain.Date.
My JSP shows a textfield and the user should enter a valid date. Everything fine, until date is of wrong format or contains illegal characters...
Problem:
ADF tries to do a setAttribute on the datefield in VO row which expects a parameter with type oracle.jbo.domain.Date. When the user entered e.g. "NiceWeather" as date, I get an IIlegalArgumentException while converting to the correct Date format. This exception isn't thrown by bc4j as AttrValException and therefore my JSP renders a global error instead of a message directly behind the date field.
I tried to validate the datefield in my DataForm and in my Action in the validateModelUpdates() method, but with no fitting solution.
Any ideas how to validate a datefield with adf/struts/jsp/bc4j?
Thanks for your help!
Torsten.

Torsen - In the first instance I'd recommed that you try and handle it declaritively using the Struts Validator Framework . See http://otn.oracle.com/products/jdev/howtos/10g/StrutsValidator/struts_validator_howto.html
There is a section in there on how to use the validator with ADF databound pages and you can check the format the user enters via generated JavaScript.
Also check out the matching sample project:
http://otn.oracle.com/sample_code/products/jdev/10g/ADFandStrutsValidator.zip - this has a data field check on it as well

The HR schema I used to build the example application had some modifications in the context of https://tuhra2.samplecode.oracle.com/ .
So after running "demo/schema/mksample" as documented in "Resetting Sample Schemas" ...

ADF Struts JSP SelectList

JDeveloper 10g JSP, Struts and ADF application.
I am developing a search form that has a number of criteria fields one of which is a selectlist.
The code that is generated when I drop the data control as a single select list onto the jsp page is as follows:
<html:select property="SearchCodeType">
<html:optionsCollection label="prompt" value="index" property="SearchCodeType.displayData"/>
</html:select>
The list is populated and I can select a value, however the value I need is the value of the prompt not the value of index (the prompt is a string) to be assigned to the parameter SearchCodeType when I submit so I can use this when adjusting the where clause of my view object to return the correct results.
I am looking for a Struts/ADF/JSP solution.

Have you guys find a way to save(commit) the multi-selection that is created as a part of the list. Steve Muenek put me in the right directions but if you guys have find a way or code please let me know since the time is running short and I would hate to move to another tool to get this functionality.
I have the implementation methods using BC4J/View Object and do understand I'll need to override the create() method but just don't know how to read the records using the iterator or from the array of strings that is saved after the user has created multiple selections.
We are using ADF Struts at least for now.
Thanks a lot,

Adf Struts + Logon + Security

Hi All
I have developed an adf web application and have some questions about logging on and security. I have read the jaas security documents and understand the process. The application will have several users.
My question is what is the best way to log users onto the model layer.
Should I use one username and password for the schema and deploy the application and maintain a user table and use the jaas security with this. Will I get record locking ?
Should every user get there own schema username and password and pass this username and password to the app module logon ?
Anyone got any other suggestions ?
Can anyone give me some advice on what ways they have handled user logons to an adf struts application.
Any help would be greatly appreciated.
Thank you
Darren

Hi,
Should I use one username and password for the schema and deploy the application and maintain a user table and use the jaas security with this. Will I get record locking ?
Actually the account a user authenticates with is not the account he works in. In web applications it is common to use a shared application account to access the database.
If you want to keep the user security provider as a table in the database then you can do this as well, with no risk of locks
Anyone got any other suggestions ?
Use container managed security with a JAAS login module that authenticates the user against the database table. This decouples application logic from security logic

ADF/Struts Generated tag code variations? Struts html:text vs Html input

Hi,
JDev 10.1.2.1
ADF/Struts
I noticed that the JDev IDE generates different code for a same component/binding combination.
Example:Data Control of type Input form with same VO selection.
Generated code for 1 field:
case 1)
JSP code:
<tr>
<td>
<c:out value="${bindings['TitleLang1'].label}"/>
</td>
<td>
<html:text property="TitleLang1"/>
</td>
</tr>
HTML output:
<tr>
<td>
Short Title Language 1
</td>
<td>
<input type="text" name="TitleLang1" value="Preliminary Demo">
</td>
</tr>
case 2)
JSP code:
<tr>
<td>
<c:out value="${bindings['TitleLang1'].label}"/>
</td>
<td>
<input type="text" name="<c:out value='${bindings.TitleLang1.path}'/>" value="<c:out value='${bindings.TitleLang1}'/>"/>
</td>
</tr>
HTML output:
<tr>
<td>
Short Title Language 1
</td>
<td>
<input type="text" name="VB_TitleLang1" value="Preliminary Demo"/>
</td>
</tr>
Case 1 generated code is obvious to me, the html name of the field equals the field binding id.
In Case 2, the VB_ prefix is added and the binding variable references bindings.fieldName.path?
Could someone explain me the second flavor?
When should we use the path reference and replace the Struts html:text tag with html input tag?
Thanks
Fred

I dont think you can mix static values and rt expressions together in attribute values.
String onBlurString = "dontLeaveItEmpty(this);referenceEntered(" + recordNumber + ")" ;
html:text styleClass="textFieldInTable" name="refrences" property="referenceName" onblur="<%=onBlurString%>" />cheers,

Problem commit w/intermedia adf struts uix & 1 step submit/commit to user

JDev 9051, ADF, Struts, ix & Intermedia
Problem:
Inserting intermedia data type (ORDSYS.ORDIMAGE) AND wanting the "commit to happen behind the scenes" so the user does not have to press submit and then commit.
I am having a problem committing a record to the DB when the form contains an intermedia data type. If I do not fill in the image column (using file upload) it works fine. My work around for now is to commit twice.
To create a new entry that contains intermedia data type (ORDSYS.ORDIMAGE) I am using the following flow of events.
NOTE: THIS DOES NOT WORK IF I UPLOAD AN IMAGE, HOWEVER, IF I LEAVE THE IMAGE COLUMN BLANK IT WORKS FINE.
01. start at browseInventory.uix
02. press create button which triggers event named createInventoryEvent
03. which gives control to createInventoryFoward
04. which fires Data Action named createInventoryAction
05. which forwards to formInventory.uix
06. user supplies data and presses the submit button which triggers event named commitInventoryEvent
07. which gives control to commitInventoryFoward
08. which fires Data Action named commitInventoryAction
09. which forwards to browseInventory.uix
NOTE: THIS WORKS IF I DO UPLOAD AN IMAGE (COMMIT TWICE)
01. start at browseInventory.uix
02. press create button which triggers event named createInventoryEvent
03. which gives control to createInventoryFoward
04. which fires Data Action named createInventoryAction
05. which forwards to formInventory.uix
06. user supplies data and presses the submit button which triggers event named commitInventoryEvent
07. which gives control to commitInventoryFoward
08. which fires Data Action named commitInventoryAction
09. which (on success) fires Data Action named commitInventoryAction_2
10. which forwards to browseInventory.uix
BTW - is there some codes I can use to display an image (Struts Config - Page Flow) on the OTN forums if I am hosting the image?
Thanks,
Bill G...

Did you ever get a soluction for the duoble commit thingie?
cause I cuirrently have the smae problem. It seems that it uses the first commit to instantiate the object, and the second commit to actually upload it to the database.

Friendly Printed Adf struts and CVS( case 1)

Dear All,
these link has good example for CVS on ADF struts for friendly printed.
Try the CSV sample (#27) at http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html.
The problem is there are no explanation in step by step fashion for new comers like me.
I try to make the same project like the no 27 example. But the searching creteria always has a value that collected from data on the database when we run it from Jdeveloper. While on the example no 27 zip file, it will appear null and we can put the criteria there for our searching....
Anybody can show me my mistakes and the step to solve these problems?

JDev10g and ADF/Struts input form errors

I followed a demo for creating an input JSP form from Business Components. However, although I can create and run a report or read-only form without a problem, I cannot create and run an input form at all as I keep getting the following error:
javax.servlet.jsp.JspException: No getter method for property FirstName of bean org.apache.struts.taglib.html.BEAN
at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:968)
Any ideas?

Justin,
This usually happen because the data binding called FirstName cannot be found in the binding container associated your JSP.
The binding container associated with your page is most likely the name of your page with UIModel.xml.
You can see the list of bindings available in the binding container by selecting the DataBinding.cpx file in the Navigator and look at the Struture Pane.
The FirstName binding might not be thre of the wrong binding container may be associated with the page.
