Steve Muench ADF Sample Applications Empty

Not sure if this is the right place to post this, but does anyone else have an issue with retrieving any of Steve's sample applications? I am able to get the zip file, but they are all empty and I get an error saying the zip file is corrupt.
I desperately need his Example #1 https://smuenchadf.samplecode.oracle.com/samples/ArrayOfStringDomain.zip
Thanks!

Weird. I have tried this on two different computers on two different networks with the same issue. Very frustrating as I really need that zip file.
5 points for the first person that posts and emails it to me at [email protected]
Thank you

Not Yet Documented ADF Sample Applications download link not working

Steve Muench Not Yet Documented ADF Sample Applications located at http://blogs.oracle.com/smuenchadf/examples/
The download link for the samples does not work. It directs us to Oracle JDeveloper Products Page instead.
Clicking on the title of any sample application used to enable the download of the sample file. Now it points to http://www.oracle.com/technetwork/developer-tools/jdev/overview/index.html
Is there an alternative way to download the sample applications?
Thanks in advance for your help.
Mitesh

Unfortunately the link https://smuenchadf.samplecode.oracle.com/samples does not work. It gives message URL is not valid.
Your samples are a very important source of reference for us. Hopefully all the samples can be migrated to the new site soon.
I am using JDev 11.1.1.2. I am using editable checkboxes is a table with RowSelection = Single. When I click on a selectBooleanCheckbox on a different row other than the current table row, the checkbox value changes at first but immediately reverts back to the previous state. It works fine so long as I remain on current row of the table. If I turn RowSelection off then I don't face this issue.
For information, I wanted to take a look at your sample 145. Using a CheckBox in an Editable Table with Boolean/Button Binding.
Thank you for your help.

Steve's ADF Sample #131 : What if adding attributes in extendsproject ?

Hi Steve,
I want to further implement your ADF sample #131 : ADF Web Application with Component Substitution
On the example there, on ExtendsProject , a new validation is added. and it changes the behaviour of the application in BaseADFWebApp.
Our requirement is :
- add new attributes on DeptEx entity in ExtendsProject
- drag those new attributes into Departments.jspx in BaseADFProject
( th ebjective is to reuse the jspx for the DeptEx with the new attributes )
Is there any any scenario to make this possible ?
Thank you very much,
xtanto

Our requirement is :
- add new attributes on DeptEx entity in ExtendsProjectThat is possible. No problem.
You'd also need to extend the view object and add the new entity attributes to the extended view object, too. That is possible. No problem.
- drag those new attributes into Departments.jspx in BaseADFProject
( th ebjective is to reuse the jspx for the DeptEx with the new attributes )That would require having a customization layer for the JSPX pages which is not available in 10.1.3, only in 11g.
The only way to have a JSPX page the reacts "automatically" to the presence of added attributes in the view object (due to component substitution) would be to design the page to be rendered dynamically based on the attributes in the data collection. Unfortunately, in 10.1.3, we only supply a "Read Only Dynamic Table" component, but not one for editable forms. The latter is supplied in 11g.

Improvement of Steve Muench's sample #62. Cascading Lists in JSF

If you go to
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html#dynamiccascadingpoplist
you will find sample application demonstrating use of Cascading ListBoxes in JSF using selectOneChoice and ADF Master/detail relation.
But it has one problem - if you delete required field "City" you can not longer use cascading list because of validation error. I came to one solution of this problem and I like share it with others.
1. add immediate="true" to selectOneChoice tag. This will prevent client-side validation (in conjunction with autoSubmit="true")
2. add
FacesContext.getCurrentInstance().renderResponse();in the end of onRegionListChanged() in backing.java to prevent server-side validation
There is no validation errors anymore, but now link between lists is broken
3. add following code to onRegionListChanged in backing.java
int position = (Integer)valueChangeEvent.getNewValue();
DCIteratorBinding regionDCIter = bindings.findIteratorBinding("RegionsIterator");
regionDCIter.setCurrentRowIndexInRange(position);Tip: easy way to get bindings in backing bean is to double click on some button in JSF design mode
4. Almost there. Cascading works but we have one small bug. Set some location to Europe/United Kingdom and commit. Now, try to change region to anything else. Doesn't works. If yours logs there is IndexOutOfBounds exception.
To solve this add following code to onRegionListChanged in backing.java:
bindings.findIteratorBinding("LocationsViewIterator").getCurrentRow()
     .setAttribute("CountryId", null);
getCountryIdSOC().setSubmittedValue(null);Tip: to create getCountryIdSOC() method you should edit binding attribute of the Country selectOneChoice
In the end your method will look something like this:
public void onRegionListChanged (ValueChangeEvent valueChangeEvent) {
     FacesContext.getCurrentInstance().getExternalContext().getRequestMap().put("RegionChanged", "x");
     bindings.findIteratorBinding("LocationsViewIterator").getCurrentRow()
          .setAttribute("CountryId", null);
     getCountryIdSOC().setSubmittedValue(null);
     int position = (Integer)valueChangeEvent.getNewValue();
     DCIteratorBinding regionDCIter = bindings.findIteratorBinding("RegionsIterator");
     regionDCIter.setCurrentRowIndexInRange(position);
     FacesContext.getCurrentInstance().renderResponse();
}Note: I casted bindings to DCBindingContainer.
I hope you will find this helpful.

To solve this add following code to
onRegionListChanged in backing.java:
bindings.findIteratorBinding("LocationsViewIterator").
getCurrentRow()
     .setAttribute("CountryId", null);
getCountryIdSOC().setSubmittedValue(null);Tip: to create getCountryIdSOC() method you should
edit binding attribute of the Country
selectOneChoice
What does that do? and what do you mean by editing the binding attribute of the selectonechoice?
Other than that I get what you're doing.

Where to get ADF Sample Applications with Documentation.

Hi All,

Question for Steve Muench - ADF/EJB & Applets?

Steve or anyone who can help - Do you have any sample demo that can demonstrate how to take advantage of ADF caching technology on the server, or an EJB solution integrated with an applet in a web application?
It is kind of late in the game, because we are about to roll out an application in our company, nevertheless we are still researching a better way for handling tremendous amount of data by our applet. We are using F1 Formula engine (spreadsheet like tech) in our applet. But, we have severe performance problems, especially in our remote locations trying to load thousands of rows in the applet and on top of that do all kinds of formatting and Excel like functionality in the applet grid at run time.
We are looking for a way to integrate ADF or EJB caching solution with our applet, so that we can cache the client data on the app server if possible, in order to improve performance.
Any guidance, suggestion and help is very much appreciated.
Thanks,
[email protected]

Hi,
my recommendation would be to use JavaWeb Start with BC deployed as EJB to the Application Server. This way you have a real client installation and don't need to download the Applet classes all the time (and JClient, assuming you use JClient, comes with a couple of libraries slowing down the initial application startup). Using EJB on the middle tier allows you to use batch mode, which reduces the number of roundtrips between the client and the server. Note that the default implementation is synchronous, which is more chatty.

ADF Sample application

Hi ,
I have to deploy some working samples for Jdeveloper ADF demo.
I am trying to use these samples : http://java.net/projects/smuenchadf/pages/ADFSamplesADFFacesUIComponents#UI_Components ;
When I download some of these samples I have the source code. To deploy them on WebLogic Server I need .war or .ear file .
I try to build them on Jdeveloper. I download and install the latest 11g Release 2 with ADF.
When I import the the project (successfully) I use the deploy option. First I create deployment profile and then EAR -file but i receive the following error :
[11:08:28 AM] Deployment cancelled.
[11:08:28 AM] ---- Deployment incomplete ----.
[11:08:28 AM] == ERROR: No Java EE modules detected in EAR archive. Deployment aborted. == (oracle.jdevimpl.deploy.ear.WeblogicAssembler)
Is there any tutorial with step by step description how to deploy these samples on weblogic server and to have this application running ?

Thanks for the help !
Now I receive the error with JDBC . I have running oracle instance but I don't know how to connect jdeveloper with this instance .

hi Cesar
I must say that the RestoreCurrentRowAfterRollback.zip file I downloaded looks a little strange
see http://www.consideringred.com/files/oracle/img/2011/RestoreCurrentRowAfterRollback-zip-20110118.png
It is a ZIP file with one single file inside it "RestoreCurrentRowAfterRollback" (no extension) which seems to be a ZIP file (add ".zip" extension).

Not Yet Documented ADF Sample Applications #113.Apply Bind Varible Val @11g

Hi ,
I am trying to apply this to 11g but I am facing some weird issues. I am using an editable inline detail table and when I edit a row and refresh the page it adds a new row with the updated value to the table.
Should I use a different way to Apply Bind Varible Values to Filter View Link Accessor RowSets in 11g ?

Thanks

Hi Frank,
Would really apprecaite your feedback and Muhammad has same issue and he is
trying work around for this issue using view accessor.
I read your wonderful blog everytime, I am stuck in problem , I would appreciate ,if you can give me answer to my issue.
Let us consider : Item , SubItem relationship.
Component : Item VO , SubItemVO , Item can have many subitem.
1.Created ItemVO
2.Create SubItemVO
3.Create View Link based on ItemVo-ItemId that is FK in SubItem table.
4.Created JSF page and Dragged ItemVO from Datacontrol to JSF Pagen as ADF ReadOnly Table.
5.Expanded Item table structure in Structure window and open the detailstamp.
6.Dragged SubItemVO in detailstamp as ADF ReadOnly table.
Expected Result :
1. ItemVO First Row
1.SubItems belonging to ITEMVO First Row
2.SubItems belonging to ITEMVO First Row
2.ItemVO Second Row.
1.SubItems belonging to ITEMVO Second Row
Current Result :
1. ItemVO First Row
1.SubItems belonging to ITEMVO First Row
2.SubItems belonging to ITEMVO First Row
2.ItemVO Second Row.
1.SubItems belonging to ITEMVO First Row
2.SubItems belonging to ITEMVO First Row
Description: Second ItemVO when expanded shows first ItemVO SUBITEMS.

Need help for file upload - reposted for Steve Muench

Hi Steve,
I have been involved developing a web application that requires a file upload operation. I have studied your example on Upload Text File and Image Example in the Not Yet Documented ADF Sample Applications section. I got the file upload part worked but could not get the original file name to populate the name field..i.e. if I upload myFile.txt to the database, the name field will be myFile.txt (not the name enter by user). Is there a way to capture the filename info? or is it possible to do so within ADF framework? I am using ADF/Struts/JSP with ORDDoc data type. Thanks very much.
Bill

Hello Nani,
You need to change any settings in 'FILE' transaction. This transaction is used to set up Logical file paths. ( In general it will be set already for your system).
You can use the following code.
DATA: LC_LOGICAL_FILENAME_EXPSRC LIKE RCGIEDIAL-IEFILE
                                                VALUE 'EHS_IMP_SOURCES'.
DATA:      L_EMERGENCY_FLAG            TYPE C.
DATA:      L_FILE_FORMAT               LIKE FILENAME-FILEFORMAT.
data : X_RCGIEDIAL LIKE RCGIEDIAL occurs 0 with HEADER LINE.
read the default pathname on application server
    CALL FUNCTION 'FILE_GET_NAME'
         EXPORTING
            CLIENT                  = SY-MANDT
              LOGICAL_FILENAME        = LC_LOGICAL_FILENAME_EXPSRC
              OPERATING_SYSTEM        = SY-OPSYS
            parameter_1             = ' '
            PARAMETER_2             = ' '
            USE_PRESENTATION_SERVER = ' '
            WITH_FILE_EXTENSION     = ' '
            USE_BUFFER              = ' '
         IMPORTING
              EMERGENCY_FLAG          = L_EMERGENCY_FLAG
              FILE_FORMAT             = L_FILE_FORMAT
              FILE_NAME               = X_RCGIEDIAL-IEFILE
         EXCEPTIONS
              FILE_NOT_FOUND          = 1
              OTHERS                  = 2.
    write :/ 'file format', L_FILE_FORMAT,
           / 'file name', X_RCGIEDIAL-IEFILE.

BeginRequest on previously used DataControls (for Oracle guys/Steve Muench)

Hi,
We are using JDeveloper 10g (10.1.2.1.0) and ADF BC+JSP in our application.
In our developer team, in tuning tasks we have detected, that all DataControls that were been used be the user in the past (same session) are activated each request (beginRequest) that user realizes, activated and taking an AM out of the pool and maybe this AM not will be used in this request, and maybe neither in any other future request from the user. Then we have that each AM that were used in the past by the user, must will be activated/passivated if pool is small size limited or pool must will be oversized (server big load situations).
When the user ends using this AM, we call its resetState method, like is recommended by Steve Muench at
Re: application modules and a logoff event (for Steve Muench)
but the next ones user requests will make the ADFBindingFilter call beginRequest on all previous AM anyway. Seems that initially the user BindingContext contains references to DataControls (DCDataControlReference) but when the user uses/gets an DataControl its reference is replaced with the real DataControl instance (DCJboDataControl), and seems that DCJboDataControl.beginRequest, gets an AM instance out of pool, I think that this will make that the AM will not be expired/cleared by the PoolMonitor.
We have hard coded a test in our application that seems to work with the normal ADF and application lifecycle (but I don't like this test too much, too much low level coding), basically the DataControl is replaced by its reference when the user ends using it.
And now the questions. Is it a normal situation? Why we must suppouse that all the AM/DataControl previously used by the user will be used in the current request? There's a normal way to do this, maybe a method that when the DataControl is marked with a flag releases it till the next time user needs it (I'd try release(int) and it didn't works in this way)? Any suggestions/explanations about this?
Comments will be very well received. Thanks in advanced.

Hi Steve,
firstly, thank you very much for your so fast answer.
Ok, I'll open a TAR in metalink. I've searched for the bug# 4566186 in metalink, but I didn't found nothing in metalink for this bug number.

Question on "Master Detail page using ADF" sample

I downloaded the "Master Detail page using ADF" sample application. I modified editDepartment.jsp page to include the Commit button as follows:
<html:submit property="event_Commit">Save and Commit</html:submit>
When I go to edit a department record and click on the new "Save and Commit" button, I SQLed the DEPARTMENTS table and noticed that the edits were not commited. I also restarted the embedded OC4J server and still get the same results. For some reason, the department view object contains the modification but the entity object doesn't. Why?

Scott,
My colleague suggested a workaround, which is to explicitly include the detail table's id in the master table's partialTargets list. So, for example, in MasterDetailDP.uix, changing:
<table model="${bindings.DepartmentsView1}"
       id="DepartmentsView111"
       partialRenderMode="multiple"
       partialTargets="_uixState">to:
<table model="${bindings.DepartmentsView1}"
       id="DepartmentsView111"
       partialRenderMode="multiple"
       partialTargets="_uixState EmployeesView312">...will cause the detail table to be updated when sorting the master table.
There is some question about whether sorting a table should actually cause the currently selected row to change - we're still discussing this point.

Ask for helps and comments for a practicing ADF sample: Entering bank transaction records

Dear experts:
I'm redeveloping a practicing ADF sample application based on an exist application system of my company.
Here is the goal for this redeveloping:
What degree of productivity can adf achieve compare to eclipse?
And hereby is a small example I began from last Monday. some progress has been achieved, but pretty lot of difficulties remained,
so I post all neccessary informations to this forum, and ask for your kind helps and comments.
Thank you all in advance!
Introduction
The X company has some bank accounts in different banks, also it’s customers may have more than one bank account in different banks. Transactions between the X company’s bank accounts and it’s new or regular customers’ bank accounts happened heavily in daily. Bank transfer records in paper form will be collected and need to be entered into an in-house Financial System(NX1) of the X company every day.
This module will implement the function of Entering Bank transactions records for NX1.
In future, this Data Entering work for NX1 will be handled by some data exchange interface automatically.
And the following implementation will be based on ORACLE XE 11g, Jdev/ADF 12c.
This link can download the document for the example, I will upload Database scripts and JDEV application files tonight.

(The above link is a website of our own. if you meet any difficulty when access it, please let me know: [email protected]).

Hi, Timo and Frank,
Thank you all for your kind replies and sound suggestions!
Now let me talk freely on this thread-and I will limit my topic scope within this Jdev/ADF Space’s theme but maybe in a more broad perspectives. And I will separate topics into different posts to avoid over length of each post. Hope you will have enough patience to read through this some long story!
Notice: Links in this article will refer to somewhere of OTN itself or a website of our own. There is no security concern on the server. For example:

What you are up to?
First of all, I need to make some introduction of myself to answer “what you are up to”.
I come from China, living and working at Shenzhen city which is close to Hong Kong. And now I am running a small software company with 20 employees, our main business is to develop database centered applications which include in-house workflow/information management systems and websites/portals for organizations.
I have a pretty strong conviction that software technology should emancipate people from routine trivial mental works, just like engines in the industry revolution free people from heavily physical works. So I have a strong inclination for everything to be “automated”.
For running a company, this “automation” will not only bring the “aesthetics of everything running by itself”, but also will mean more productivity, quality and profits.—After all, no-living stuff is always cheaper than living creatures, let alone to say human beings.
However, when we software industry tried to automate business fields for our clients, the process of making software itself was still a manpower intensive, less-automation business. and this result a expensive products.
More than 15 years ago, when I began to work in an IT department of a big organization, I got to know the Oracle Designer/Developer 2000, and have being a diligent FORM/REPORT programmer for more than 4 years. I like the concept and practice of declarative design and automated generation.
And then more years past, and I left that organization and began to run a software company myself. And during these days, the mainstream technology of software development had been web oriented, Java/J2EE which I had no idea totally. But we have other guys who had expertise on it. So I just leave these works and decisions to them. And it seemed works at the beginning.
But after several years of business operation of application development for clients, I found this was a difficult-money-earn business. Even if our guys had worked hard, project schedules’ delay, over budget, clients’ complain was easily happened. Sometime we had more projects/contracts than what we can undertake, but we dare not to hire more people. I was confused:
-Was it a common situation in this field all over the world?
-What’s the key factor should responsible for?
-Where to start to improve the situation?
I know there are many factors should responsible, it’s a complex situation. Find more talented people and give better incentives for them to work hard is one choice—but it’s also a difficult task especially for a small company like ours. So to start from easy and confine solution’s scope is:
-We have these guys now, what we can do best?

Previous to this, I had to include the bc4jhtml.jar file as a library in application.xml, and I've tried using the two bc4jhtml.jar files, but neither one seems to work.
I'm thinking that there must be something simple that I'm missing with the servlet setup...
Thanks!

I tried the wayback machine, but unfortunately, it doesn't cache the SWF files either :( I do have a copy of some (ok one) of Steve's old videos (the one that shows how to do a dropdown list in an editable table, back before it was easy to do), but unfortunately, none of the search ones.

Dynamic JDBC credentials example application from Steve Muench

Apologies for this newbie question...but I'm trying to understand the Dynamic JDBC credentials example application from Steve Muench:
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html#14
I think I understand most of it but the one bit I dont understand is why it customizes the ADF Page Lifecycle (DynamicJDBCADFPhaseListener, DynamicJDBCPageLifecycle, DynamicJDBCPageLifecycleContext).
Can anyone explain to an ex-forms developer why this code is there?
I'm also trying to work out a way for the session to be invalidated when the user logins again
e.g. a user logins, he doesnt use the logout function but uses the back button to go back to the login page. when he logs in with another set of credentials, would a new session start or as i supsect, it would use the original login credentials?
Thanks

You can ignore those three classes in the example. They are not related to the dynamic credential solution, and must have been left over from some other example I evolved into what you see. Sorry to have cluttered up the implementation with stuff that isn't really contributing to the actual solution. DOH!
