How to test or view data if the source is XML files..?

Hi,
I just got a doubt..
How can we test or view data from BI Admintool if the source is XML files.
If it is database we can perform "Update Row Count" or "view data" from physical layer.
I am just going through the "sample sales" example and could not find the option to test
connectivity with xml file..(I can see the directory which points to samplesales and xml files..
but how can I view those data in BI admintool)..
Help would be appreciable..
Thanks and Regards,
Sri.

Hi Sri,
Yes, this option is not available for XML and multidimensional sources. Check "Show row count in physical view" in Table 2-1 documented here ,

Enhance Req: Business Components Browser close data viewer

Hi JDev team
Regards the Business Components Browser in JDev 11g TP with an open data viewer. To close the data viewer you need to right click on the tab then select Close.
Can you raise an enhancement request please for a 1 click close facility, such as floating the mouse over the tab, an X button appearing in the right side of the tab, which with 1 click closes the tab.
Thanks,
CM.

Hi Andy,
I try set a where clause using the message:
Set where Clause parameter using UIX , but my UIX Page have 2 messageChoice's of different ViewObject's, then I need implement this Java Class:

How to create dynamic View Object and Dynamic Table

Dear ll
I want to create a dynamic view object and display the output in a dynamic table on the page.
I am using Jdeveloper 12c "Studio Edition Version 12.1.2.0.0"
This what I did:
1- I created a read only view object with this query "Select sysdate from dual"
2- I added this View object to the application module
3- I created a new method that change the query of this View object at runtime
    public void changeVoQuery(String dbViewName) {
        String sqlstm = "Select * From " + dbViewName;
        ViewObject dynamicVo = this.findViewObject("DynamicVo");
        if (dynamicVo != null) {
            dynamicVo.remove();
        dynamicVo = this.createViewObjectFromQueryStmt("DynamicVo", sqlstm);
        dynamicVo.executeQuery();
4- I run the application module for testing the method and I passed "Scott.Emp" as a parameter and the result was Success
5- Now I want to show the result of the view on the page, so I draged and dropped the method from the data control as a parameter form
6- I dragged and dropped the view Object "DynamicVo" as a table and I choose "generate Column Dynamically at runtime". This is the page source

How can I remove an object using Photoshop Elements 7?

How can I remove an object using Photoshop Elements 7?

You could probably use the 8 point garbage matte in this situation. I personally think the 8-point garbage matte is a bit cumbersome, but it should get the job done.
1. Use the Razor Blade tool to place a cut before and after the shot with the bottle.
2. Select the bottle clip.
3. Press and hold Shift + Option, then drag the bottle clip up one track. This should create a duplicate clip directly above your original clip. (I'll refer to this duplicated clip as bottle2.)
4. Locate the 8-point Garbage Matte filter and apply it to bottle2.
5. Locate the Gaussian Blur filter and apply it to bottle2.
6. Control click bottle1, and uncheck the "Clip Enable" setting from the shortcut menu. This will disable that clip.
7. Double click bottle2 to load it into the Viewer. Then select the Filter tab.
8. For the Garbage Matte filter, you'll notice 8 rows of numbers, these are the current locations for the control points, which you should be able to see in the Canvas. Start with point #1, and click the "+" button in the filters area, then in the Canvas click and drag to move the point. When you release the mouse button, you'll need to reclick the "+" button in the filters tab. Repeat these steps until you've isolated the bottle.
9. Feather the edge of the matte.
10. Adjust the Blur amount.
11. Reenable bottle1. Playback the clip and make any necessary adjustments.
Depending on your experience with Motion, you might also want to try sending bottle1 to Motion, then use Motion to control the layering.

Have you seen this thread…

The short story is that the new 'certifcate checking' system could be downloading large amounts of data, you can turn it of as follows…

Turning off CRL & OCSP checking in the Certificates Preferences in Keychain Access solved the problem.
You can do as others have done, install Little Snitch & use the Network Monitor to view what is happening, that thread has some good advice. http://www.obdev.at/products/littlesnitch/index.html
@Topher, Activity Monitor is a bit pants for tracking processes that respawn or just go away (I assume its because it's an on-demand job, have you got a nice article on 'mach services', Linc confused me !? ).
ocspd seems to do that in my limited testing,
Little Snitch is the easiest way to monitor & you can get away with the free demo for long enough to test if funds are tight.

View objects referencing the same entity

The behaviour occurs in every version of jdeveloper ADF BC i have tried so far (10g, 11g).
I have 2 updatable view objects referencing the same entity object. When i create a new record using the first view object and before commiting the data to the database i navigate to the second
view object. Suprisingly the second view object is populated with the same data that is posted on the first view object. It seems like both view objects are referencing the same entity object instance.
Is any way to overcome this strange behaviour.
Thanks

As Timo says think of the EO as a record cache. If you had 700 VOs all based on the same EO, it would be ideal to store the same record(s) 700 times in the midtier as it would consume vasts amount of memory. Thus the EO cache.
If you do want to separate the VOs, you've 3 options:
1) Use separate EOs for each VO (not ideal)
2) Expose each VO under their own root level Application Module - a separate EO cache instance for each VO will be created at runtime - however you need to be careful between the VO/EO pairs, you don't update the same record, as you'll get record locks/contention
3) If you're using task flows in 11g, use the Always Begin New Transaction option for each screen/fragment for each VO. This is the equivalent of 2 but from the task flow level - however again you need to be careful on record locks.

How to create a view object and attach with extended AM

Hi,
I tried to create new vo and attach this vo with the extended AM. But it is throwing error like 'PC.NAME : invalid identifier' (Actually this PC.NAME is exiting one).
Now i want to know how to create a view object similar like seeded one but with one additional condition in the where clause.
It is possible though extension, but i want to create two view object similar like seeded one, one with some other condition in the where clause
and another one with some other condition.
So for my requirement, i'll extend one VO and i'll add my condition but how to do it for second condition.
But i want same seeded VO with two different condition.
Any suggestions please,
SAN

SAN,
There is no need to attach the newly created VO with extended AM. You need to attach the same with the standard AM.

Gyan

Developing a 2 page form, username on the 1st page, password on 2nd how can i force FF to use the username from previous page when it asks to remember acct info?

I am developing a 2 page signup form, where the person enters their username on the 1st page and password on the 2nd.
When I test the form, FF asks to remember my password for the site - however it thinks the zipcode (field above the password) is the username on the account.
I have tried to put their username/email in a hidden field on the 2nd page, just above the password field - and that did not work.
How can i force FF to use the username from previous page when it asks to remember acct info?

This website is using autocomplete=off to prevent Firefox from saving and filling the name and password.
You can remove autocomplete=off with a bookmarklet to make Firefox save names and passwords and other form data.

3. I create a view link to create master-detail relationship for these 2 view objects.
masterview.SourceBlock (1)->detailview.SourceBlock (*).
4. I create a tree table using these 2 view objects with master-detail relationship.
When I set default value for variable bindings of these 2 view objects and the matching records exist, tree table can work well. I can expand the master row to display detail row in UI.
But I need to pass in dymamic parameter value for variable bindings of these 2 view objects, tree table cannnot work again. when I expand the master row and no detail row are displayed in UI.
I am sure that I pass in correct parameter value for master/detail view objects and matching records exist.
Managed Bean:
        DCIteratorBinding dc = (DCIteratorBinding)evaluteEL("#{bindings.MasterView1Iterator}");
        ViewObject vo = dc.getViewObject();
        System.out.println("Before MasterView1Iterator vo.getEstimatedRowCount()="+ vo.getEstimatedRowCount());
        System.out.println("Before MasterView1Iterator ShiftModeCode="+ vo.ensureVariableManager().getVariableValue("ShiftModeCode"));
        vo.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
        vo.ensureVariableManager().setVariableValue("DateTo", dateTo);
        vo.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
        vo.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
        vo.executeQuery();
        System.out.println("MasterView1Iterator vo.getEstimatedRowCount()="+ vo.getEstimatedRowCount());
        DCIteratorBinding dc1 = (DCIteratorBinding)evaluteEL("#{bindings.DetailView1Iterator}");
        ViewObject vo1 = dc1.getViewObject();
        System.out.println("Before DetailView1Iterator vo1.getEstimatedRowCount()="+ vo1.getEstimatedRowCount());
        System.out.println("Before DetailView1Iterator ShiftModeCode="+ vo1.ensureVariableManager().getVariableValue("ShiftModeCode"));
        vo1.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
        vo1.ensureVariableManager().setVariableValue("DateTo", dateTo);
        vo1.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
        vo1.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
        vo1.executeQuery();
        System.out.println("after DetailView1Iterator vo1.getEstimatedRowCount()="+ vo1.getEstimatedRowCount());
5. What's wrong in my implementation? I don't have no problem to implement such a tree table if using simple master-detail tables view object, but now I have to use such 2 view objects using complex SQL for my requirement and variable bindings are necessary for detail view object although I also think a bit strange by myself.

                ViewObject accessorVO = rs.getViewObject();
                accessorVO.setNamedWhereClauseParam("LowSalary", lowSalary);
                accessorVO.setNamedWhereClauseParam("HighSalary", highSalary);
            executeQuery();
but I have a quesiton in this way. in code snippet, it is first getting current row of current master VO to determine if update variables value of detail VO. in my case, current row is possibly null after executeQuery() of master VO and I have to change current row manually like below.
any idea?
            DCIteratorBinding dc = (DCIteratorBinding)ADFUtil.evaluateEL("#{bindings.SSForecastSourceBlockView1Iterator}");
            ViewObject vo = dc.getViewObject();
            vo.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
            vo.ensureVariableManager().setVariableValue("DateTo", dateTo);
            vo.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
            vo.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
            vo.executeQuery();
            vo.setCurrentRowAtRangeIndex(0);
            ((SSForecastSourceBlockViewImpl)vo).synchornizeAccessorVOVariableValues();

How to access a view object under a nested appmodule in servlet

Hi,
Can anyone tell me how to access a view object under a nested appmodule in a servlet?
I know that I can use
ApplicationModule app = Configuration.createRootApplicationModule(amDef, config);
ViewObject vo = app.findViewObject(viewObjectName);
to get hold of an appmodule and view object.
But in a nested appmodule, for example, I have am0 as root, am1 as child, and voZ within am1, what should I use for this amDef? config? and viewObjectName?
Your help would be much appreciated.

How can I write new objects to the existing file with already written objec

Hi,
I've got a problem in my app.
Namely, my app stores data as objects written to the files. Everything is OK, when I write some data (objects of a class defined by me) to the file (by using writeObject method from ObjectOutputStream) and then I'm reading it sequencially by the corresponding readObject method (from ObjectInputStream).
Problems start when I add new objects to the already existing file (to the end of this file). Then, when I'm trying to read newly written data, I get an exception:
java.io.StreamCorruptedException
at java.io.ObjectInputStream.readObject0(Unknown Source)
at java.io.ObjectInputStream.readObject(Unknown Source)
Is there any method to avoid corrupting the stream? Maybe it is a silly problem, but I really can't cope with it! How can I write new objects to the existing file with already written objects?
If anyone of you know something about this issue, please help!
Jai

Here is a piece of sample codes. You can save the bytes read from the object by invoking save(byte[] b), and load the last inserted object by invoking load.
