For Steve regarding example #88

Hi Steve,
thanks for nice example - finally someone cares about JSF and Graph.
One note - As I already mentioned on this forum there must be some bug in using Graph with JSF (maybe also JSP - I didn't test).
In your example: try to make some folder in your public_html /folder e.g. and move your .jspx page there - try to run that page = I am getting following error:
javax.servlet.jsp.JspException: data attribute evaluates to null
     at oracle.jbo.html.jsp.graph.GraphTag.doStartTag(GraphTag.java:212)
     at folder.PageWithDataAndGraph_jspx._jspService(_PageWithDataAndGraph_jspx.java:548)
     [folder/PageWithDataAndGraph.jspx]....................................
do you know why?
btw. Don't you have feedback possibility on your blog?
thanks,
Branislav

Hi Branislav,
Weird behaviour. I have the same. While trying out some Graph stuff in a "demo" app everything worked fine. When I wanted to use this in my "real" application with a structure like ../pages and ../lov and ../whatever it just doesnt work anymore.
I will play around with this for some time and I hope I'll find an explanation.
Maybe, if you figure it out first, get back to the forum.

Hi everyone,
I have implemented Steve's example 105 for unique key validator using ADF Business components.
Can anyone explain to me how can i implement this functionality using EJB?
Thanks

Set the control hint like the format mask or tooltip on the "Ssn" attribute, then you can edit the Java message bundle directly.

It seems that you do not understand the problem at hand. I can listen on a m3u list using iTunes, VLC and other players, but I wish to listen on m3u lists as streaming music when I am on sites such as eMusic. For instance, I cannot listen on sample music at eMusic, but must download it first. Thus, it is not possible to listen on streaming music with Firefox. On the other hand, Opera and Safari handle m3u streaming music very well.
Can you listen streaming music or samples at eMusic using Firefox without downloading m3u-list on your local disk?

ADF BC : using UI Locale to translate data (Steve M. example 95)

hi
In his example 95, Steve Muench suggests an approach to "Change Preferred UI Locale with a Button in the Page".
I have made some minor modifications to this example, using JDeveloper 10.1.3.3.0, in an attempt to make it work with "translated data".
(1) I added a bind variable "LanguageBVar" and an attribute "CalculatedTranslatedDnameAttribute" to "DeptView" with this expression:
nvl(decode(:LanguageBVar, 'en', dname || ' (en)', 'it', dname || ' (it)'), dname || ' (language not supported)')(2) I added this new attribute to the table and the form on TestPage.jspx
(3) I implemented the executeQuery() method in DeptViewImpl.java like this:
public class DeptViewImpl extends ViewObjectImpl
     public void executeQuery()
          Locale vLocale = getApplicationModule().getSession().getLocale();
          System.out.println("DeptViewImpl.executeQuery()"
               + " : getName() = " + getName() + ", vLocale = " + vLocale);
          setLanguageBVar(vLocale.getLanguage());
          super.executeQuery();
}(4) If I run TestPage.jspx in JDeveloper, my "translated Dname" column shows "translated data" with suffix "(en)".
(5) If I click on "Italian", all the labels change, but my "translated Dname" column still shows "translated data" with suffix "(en)".
(6) After that I added a button to execute "DepartmentListIterator" using an "Execute" binding.
(7) Again, as in (4), I run the page and see the same behaviour and this output on the console:
DeptViewImpl.executeQuery() : getName() = DeptView, vLocale = en
DeptViewImpl.executeQuery() : getName() = DepartmentList, vLocale = en(8) Again, as in (5), I click on "Italian" and see the same behaviour (no extra output on the console in this step).
(9) If I click on the "ExecuteDepartmentListIterator" button, no "translated data" changes on the page, although this line is added on the console:
DeptViewImpl.executeQuery() : getName() = DepartmentList, vLocale = itThe modified version of this application, as described here, is available at (check README.txt):
http://verveja.footsteps.be/~verveja/files/oracle/ChangeLanguageInTheUIForData-v0.01.zip
question:
How can I make this application show "translated data" when changing the UI Locale, as in step (5).
However it is important that a solution for this would be as "non-intrusive" as possible because I would like to be able to use it in an application that has lots of translated data and where the user should be able to change his preferred language on each page.
many thanks
Jan Vervecken

Thanks for your reply Steve.
In your updated testbindlocale.zip example, the buttons "Italian" and "Inglese" behave as expected. The "TranslatedDname" column has the correct translated data.
So, I modified the example in ChangeLanguageInTheUIForData-v0.04.zip, in a similar way an moved up the call to "super.prepareRender(lfContext)" before the check on the Iterator Bindings in the current Binding Container, like this:
public void prepareRender(LifecycleContext lfContext) {
    App app = (App)ELHelper.get("#{App}");
    Locale preferredLocale = app.getPreferredLocale();
    UIViewRoot uiViewRoot = FacesContext.getCurrentInstance().getViewRoot();
    System.out.println("CustomFacesPageLifecycle.prepareRender()"
      + " : preferredLocale = " + preferredLocale
      + ", uiViewRoot.getLocale() = " + uiViewRoot.getLocale());
    boolean changedLocale = false;
    if (preferredLocale == null) {
        app.setPreferredLocale(uiViewRoot.getLocale());
    } else {
        if (preferredLocale != uiViewRoot.getLocale()) {
//        if (!preferredLocale.equals(uiViewRoot.getLocale())) {
            System.out.println("CustomFacesPageLifecycle.prepareRender()"
              + " : preferredLocale = " + preferredLocale
              + ", uiViewRoot.getLocale() = " + uiViewRoot.getLocale()
              + " : different so the Locale has changed");
            uiViewRoot.setLocale(preferredLocale);
            changedLocale = true;
    super.prepareRender(lfContext);
          if (changedLocale)
               DCBindingContainer vDCBindingContainer =
                    (DCBindingContainer)lfContext.getBindingContainer();
               ArrayList vIterBindingList = vDCBindingContainer.getIterBindingList();
               for (Object vIterObject : vIterBindingList)
                    JUIteratorBinding vJUIteratorBinding =
                         (JUIteratorBinding)vIterObject;
                    ViewObject vViewObject = vJUIteratorBinding.getViewObject();
//                    if (vViewObject.getVariableManager().findVariable("LanguageBVar") != null)
                    if (vViewObject instanceof SessionLocaleBasedVO)
                         System.out.println("CustomFacesPageLifecycle.prepareRender()"
                              + " : calling executeQuery()"
                              + " : preferredLocale = " + preferredLocale
                              + ", uiViewRoot.getLocale() = " + uiViewRoot.getLocale());
                         vViewObject.executeQuery();
}(h1) If I run TestPage.jspx, my "translated Dname" column shows "translated data" with suffix "(en)" and I see this output on the console:

DeptViewImpl.executeQueryForCollection() : getName() = DepartmentList, vParamNV[0] = LanguageBVar, vParamNV[1] = enSo, this seems to behave similar to your updated testbindlocale.zip example.
about determining whether the Locale has changed
Consider this scenario ...
(i1) Run TestPage.jspx and the "translated Dname" column shows "translated data" with suffix "(en)", the same as in (h1).
(i2) Select a different row in the table, and click the "Edit Number on AnotherPage" button. This output is added on the console:
CustomFacesPageLifecycle.prepareRender() : preferredLocale = en, uiViewRoot.getLocale() = en
CustomFacesPageLifecycle.prepareRender() : preferredLocale = en, uiViewRoot.getLocale() = en
CustomFacesPageLifecycle.prepareRender() : preferredLocale = en, uiViewRoot.getLocale() = en : different so the Locale has changed
CustomFacesPageLifecycle.prepareRender() : calling executeQuery() : preferredLocale = en, uiViewRoot.getLocale() = en
DeptViewImpl.executeQueryForCollection() : getName() = DeptView, vParamNV[0] = LanguageBVar, vParamNV[1] = en(i3) Without entering an "Example Number ...", just click the "Update and Back to TestPage" button. This output is added on the console:
CustomFacesPageLifecycle.prepareRender() : preferredLocale = en, uiViewRoot.getLocale() = en
oracle.adf.controller.faces.lifecycle.FacesPageLifecycle addMessage
WARNING: JBO-35007: Row currency has changed since the user interface was rendered. The expected row key was oracle.jbo.Key[20 ] ... and the "JBO-35007: Row currency ..." message also shows up on the page.
(i4) Click the "Update and Back to TestPage" button again to return to the "start page".
If I try a scenario similar to "i1 to i4" where I do provide an "Example Number ..." in step (i3), the first row gets updated instead of the one I selected in step (i2).
To imporve this behaviour I replaced this line ...
        if (preferredLocale != uiViewRoot.getLocale()) {... with this line ...
        if (!preferredLocale.equals(uiViewRoot.getLocale())) {And after that, a scenario like "i1 to i4" behaves like this:
(j1) Run TestPage.jspx and the "translated Dname" column shows "translated data" with suffix "(en)", the same as in (h1) and (i1). But only this output is added on the console:
DeptViewImpl.executeQueryForCollection() : getName() = DeptView, vParamNV[0] = LanguageBVar, vParamNV[1] = en
DeptViewImpl.executeQueryForCollection() : getName() = DepartmentList, vParamNV[0] = LanguageBVar, vParamNV[1] = en
CustomFacesPageLifecycle.prepareRender() : preferredLocale = en, uiViewRoot.getLocale() = en(j2) Select a different row in the table, and click the "Edit Number on AnotherPage" button. This output is added on the console:

CustomFacesPageLifecycle.prepareRender() : preferredLocale = en, uiViewRoot.getLocale() = en ... and no message on the page, just returning to the "start page".
If I try a scenario similar to "j1 to j3" where I do provide an "Example Number ..." in step (j3), the correct row is updated.
But, if I precede a scenario like "j1 to j3" with an explicit language change, things go wrong again.
(k1) Run TestPage.jspx and the "translated Dname" column shows "translated data" with suffix "(en)", the same as in (h1), (i1) and (j1).
(k2) Click on "Italian", the "translated Dname" column shows "translated data" with suffix "(it)", similar to step (h2).
(k3) Select a different row in the table, and click the "Aggiorna Numero con AnotherPage" button. This output is added on the console:
CustomFacesPageLifecycle.prepareRender() : preferredLocale = it, uiViewRoot.getLocale() = it
CustomFacesPageLifecycle.prepareRender() : preferredLocale = it, uiViewRoot.getLocale() = en
CustomFacesPageLifecycle.prepareRender() : preferredLocale = it, uiViewRoot.getLocale() = en : different so the Locale has changed

So, ...
It looks like some "row currency issues" remain with this approach.

1 Question for Steve

Hi, Steve!
I'm trying to run the XMLLoader Utility from your book, with a SAXParser and using the MultiTableInsertHandler class, to store a large xml file in several database tables.
When I run the XMLLoader I always get 'Deadlock breakpoint occurred at line 474 in file [C:\Program Files\Oracle\JDeveloper 3.1.1.2\jdbc\lib\oracle8.1.6\classes12.zip]\oracle\jdbc\driver\OracleConnection.class.' after some inserts into the tables.
These inserts are made correctly...
I think this is a problem related with JDBC Thin Driver or it's configuration, but i'm not sure and i just don't know how to solve it.
Can you please help me out with this?
Good work.
Bye.
null

Hi again, Steve!
In fact, I've tried also with the OCI8 jdbc driver and it still doesn't work... the difference is that the number of inserts is a little bit higher before the deadlock appears...
Meanwhile, I found that Chris Cooper has faced this same problem, and posted it in this same forum by the 6th of November 2000... I quote him here:
"I'm using XSU to load a large amount of data into an 8.1.6.1.0 Solaris instance of Oracle from XML files preformatted into the usual ROWSET/ROW DTD.
I take the files and break them down into smaller files (80Mb being a bit big for DOM to handle I'm sure you'll agree).
Once this stage is complete, I iterate through all these small files and use OracleXMLSave to insert the values into truncated tables.
The problem is that I get an intermittent error where the application just locks up.
I am developing using JDeveloper 3.1.1.2, and when I have debugging enabled, the message that comes up is that a deadlock breakpoint has been hit!
The problem here is that, the application is the only connection to the schema, and there is only one connection. I don't see how I can get into a deadlock situation unless this is a deadlock within the development env.
When I examine the data, all the rows in the file that caused the lockup have been successfully inserted, so the implication is that it is the cleanup that is causing the problem.
Has anyone got any ideas? Or has anyone come upon this one before and found a work around?
I have written a thread manager to spin each load off to a separate thread, which gets terminated if the load takes too long, but this still leaves a connection with a lock that I am unable to clean up. (Well it appears to be a lock but there is no entry in v$locks!)
Thanks for your time and attention,
Chris Cooper"
The only difference that I detect between Chris' case and mine is that I'm running Oracle in a Windows NT Server...
Since the problem doesn't seem to be dealt with thin or oci8 driver, do have you any suggestion of what may be happening here?
Thanks again for your time!
My best regards.

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.

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.

License Information for Adventure Builder Example Application

Hello All,
We wanted to use the example application Adventure Builder in one of our research projects as a case study. (Link to adventure builder: http://java.sun.com/developer/releases/adventure/). However, I am not very sure about the license they use. (http://java.sun.com/developer/releases/adventure/adventure-1_0_1-license.txt). We want to use both the architectural documents available at AdventureBuilder wiki and the source code of the application. For the architectural documents, however, we are not sure, whether, we can use them in our project and publish our results based on them or not?
Any help will be appreciated.
Best Regards

Looking for lab view example

My application consists of collecting data from a bank of sensors as pressures and tempratures vary. I would like to run a lab view VI that tests the sensors, varies the environment and keeps track of all results, sorting them into good and bad. Each sensor needs to be tested in different pressures, then the temprature increases and the pressure test begins again. If there is a lab view example that might be able to get me started, I really need to find it. Thanks for any and all help.

There are a number of examples that ship with LabVIEW and their usefulness will depend on information not specified in your questions - such as what version of LabVIEW you have, what type of DAQ card(s) you have, and if you are using any SCXI hardware. If you open LabVIEW and go to Help >> Find Examples, you can search through a number of different examples.
For the application it sounds like a good place to start would be with an Acquire to Spreadsheet type of file that reads, graphs, and logs data. From there, depending on what you mean my using the card to vary the environment, you can find other examples of AO and DIO to perform these type of functions. These examples will give you a good starting place as to how a LabVIEW program works and the general flow
that you will need to follow.
Also, depending on your other needs, you might considering looking into examples with triggering to enable you to control when your program starts.

For transaction data, transaction LBWE is there,similarly is there something like this for master data.
Another Question:

Hi,
I read the demo program. Sorry i am unable understand the concept what is going on in the program. I saw other examples with XML codings with parsing but in this no XML codings are there. I am unable to understand the concept what is going on in J2ME with web services. Give me a simple example if u did any application related to this topic. I have to receive today from the website(web server). Help me...

Looking for simple search example using SELECT

Can anyone link me to an example of how to create a basic search page where the search criteria is selected in a drop-down list (<SELECT> in HTML)?
Here's where I'm coming from so you have a better idea of what I'm trying to do. I've created a search page by creating a method in my App Module java class using setWhereClause(), then dropped my view onto my web page as a read-only table, and finally dropped the method and parameter as a command button and input text field, respectively. This works fine, but I'd like to replace the input text field with a select box so that the users will not have to type in their search criteria. I'd like to populate the drop-down with data from a table, which will then be sent as the argument for the method.
I can create a ViewObject that contains the data I need, but I'm not sure where to go from there. I don't know how to create the drop-down list or connect the command button to the list. (Ultimately, I'd like to have the search text submitted when the drop-down changes, but I'll settle for pressing the button for now). I've fooled with using the LOV component, but without any luck.
Step-by-step would be great, but if you can point me to an example, some documentation, etc., that would be great too.
Thanks,
Andy

Excellent - Thanks for the link to the sample code page. I thought I had seen all the tutorials, etc. but for some reason never came across this page. The example you cited looks like it's just what I'm looking for.
(Edit - For anyone who's interested, here's a step-by-step for creating a databound drop down list:
