What is the correct way to dynamically change the View?

hi @,
In my application I have a radiobuttonbyKey UI element and based upon the key I have to hide and/or show a particular UI combination placed in the group UI element basically dynamicallly modifying the view.
I have 2 option one on radio button action I will change the visibilkity property of the group or in the wdModifyView method of the View.
I want to know which is the best way in such situation as per MVC concepts to dynamically modify view in UI action or in wdModifyView method.
Regards,
Amit

I would just bind the "visible"-property of the Group to a context attribute (DDIC type "Visibility") and set the value of that attribute from the onSelect-handler of the drop-down list. No need for code in wdDoModifyView().

What's the correct way to handle changes in RDBMS/DBadapter?

In my project all changes to the database are not done via Jdeveloper but via TOAD. This means DBadapters must be made aware of changes in the database.
I tried to re-run the DBad.apter wizard twice (2 different services) - to make it aware of changes in the DB. Both times it failed. I think was after the import database tab. The next tab was just blank.
So what's the correct way of reconile changes in the db backwards into Jdev?
BTW, in the DBadapter wiz its not possible the remove a already imported table. How do I come across the situation where I want the DBadapter to point to af different table? - and possibly remove old references to another one - which might have been removed in the DB.
As It is now - I have to re-work all my DBadapters, which is not very much fun...
Rgds, Henrik

Trust me, I hv done that umpteen nbr of times.
I hate BA's coming to me with changes, for which I hv to modify the DB adapter.
One big loop-hole with BPEL is if we try to modify the adapters/toplink, it doesnt tend to work properly.
The manthra for such modifications is ... "recreate", which is definetely not a good practise.
You may not like but gottu live with it, my friend.
Pointing to a different table, I achieve it by doing a "Shift+Delete" to all the references of the old table in the BPEL project ... :|
There isnt a specific provision in the wzd (I am not sure of the latest version, though).

Attn - The correct way to connect to the repository

From iFS Product Management.
Many people appear to be having trouble connecting to the repository and are using the wrong API calls to do. The recommended API calls changed between beta and production. For the production release here is the correct way to connect:
1. Four pieces of information are need to connect to the repository
1. The iFS User Name
2. The iFS User's password
3. The properties file to be used
4. The database password of the user who owns the iFS Schema
This is different from the beta where the database password was hardcoded into the properties file.
Note that any TNSNAMES information is still containing in the databaseURL entry in the properties file.
package ifs.demo.samples;
import oracle.ifs.beans.*;
import oracle.ifs.common.*;
import java.util.Locale;
public class ConnectionTester extends Object {
public static LibrarySession testConnection()
throws IfsException
LibraryService service = new LibraryService();
CleartextCredential me = new CleartextCredential("gking","ifs");
ConnectOptions connect = new ConnectOptions();
connect.setLocale(Locale.getDefault());
connect.setServiceName("IfsDefault");
connect.setServicePassword("manager");
return service.connect(me,connect);
public static void main(String[] args)
try {
LibrarySession ifs = testConnection();
ifs.disconnect();
} catch (IfsException e) {
IfsException.setVerboseMessage(true);
e.printStackTrace();
Note that in this example "gking" is the iFS user name, "ifs" is the gking user's ifs password. "manager" is the password of the database user who owns the iFS Schema.
"IfsDefault" is the server properties file that describes the ifs connection. This file is in called "IfsDefault.properties" and is located in the package oracle.ifs.server.properties". This means that the folder that contains the 'oracle' folder that is the root of this package must be referenced in the class path when running this example.
Note, if you use the older, 3 argument form of the connect you will get an unable to connect exception as the iFS will not have the Schema Password.
null

When I run the example below on Solaris (after setting the CLASSPATH etc., I get a oracle.ifs.common.IfsException: IFS-21008: Login Failure
oracle.ifs.common.IfsException: IFS-10170: Invalid name/credential.
(I am providing all 4 pieces of information for connecting)
When using the web interface the same userid and password work fine (system/manager).
Please help.....

What's the correct way to get changes in my iTunes library to sync to my iPod

It's been a few years since I've used itunes, so please bear with me.
I'm trying to get my ipod setup but something seems weird. In the past, if I made changes to my itunes library, then plugged in my ipod, those changes would immediately sync. It's not doing that now. When I plug the ipod in, I click on the ipod symbol near the top-right to get to the connected ipod. If I click on "on this ipod" I can clearly see that the old files/metadata are still present. When I click the "sync" button down at the bottom (next to the storage bar) nothing happens. If I click on "Music" near the top (between Summary and Movies) there's a check-box next to "Sync Music" but when I click that it says "Are you sure you want to remove existing music, movies, and tv shows from this ipod and sync with this itunes library?". I don't want to have to wipe the thing clean and then re-write EVERYTHING again every time I want to make a change, that's crazy.
So what am I missing here? Is there some setting that would make it work the way it did in the past, automatically syncing changes as soon as I plug in the ipod? If not, what's the best way to get the changes to sync over without having to wipe the ipod clean every time? Does the "Sync Music" option I mentioned not actually remove everything, but just sync any changes that were made? That's the only thing I can come up with.

Because you are not syncing your music (you have Sync music unchecked).
If not, what's the best way to get the changes to sync over without having to wipe the ipod clean every time? Does the "Sync Music" option I mentioned not actually remove everything,
It shouldn't wipe everything but it will make the iPod match what you have selected in iTunes. So if it's on your iPod now and also in iTunes, it won't remove it then re-add it.
Is everything on your iPod actually in iTunes? If so, click away.
How do I get it to stay checked then? I've checked it and gone through the sync process, but every time I go back to that window, it's un-checked again, and I have to sync manually.
Ok, that's what I was hoping, it just syncs any changes. I've done it this way a couple times but couldn't tell for sure if it was just removing then re-adding evertying or if it was just syncing changes.

What is the correct way of quieting down the CPU fan?

Hello,
Let me first ask for recomendations on an aftermarket CPU Heatsink and Fan to replace the stock one on my AMD x4 965 Black edition CPU please, My profile on this forum has my computers equipment and case etc. But if you need more info please just ask..
Would somebody please give me instructions on how to make the stock CPU cooling fan run at a more appropriate RPM when at idle and or when running with a load on it please.
The stock CPU cooling fan usually runs up there at about 5,000 to 5,500 CPM even when at idle and it's seriously insanely loud, too loud to be sitting next to it and trying to concentrate on work or even playing a game.
I've been loading up the Overclockers Center program and choosing the default profile since that seems to have the CPU fan set to around 3500 RPM which produces an acceptable noise level for the fan. But I figure that having to load up Overclockers Center program and choosing a profile each time I load my computer is probably not the way I should be doing it, so if somebody wouldn't mind, please explain what I need to set in the Bios or elsewhere so that the CPU cooling fan is not blowing my head off with noise all the time.
Thanks

Hello
1-This mobo is strong enough to support such a heavy coolers.Now i have i installed TUNIQ TOWER EXTREM( because of porformance/price here) that is as heavy as v8. although the company dosnt gauranty the failure but it works very well on my case and i rotate and opening the case many times for some experiments!!
2- ZALMAN is a famous cooler producer.I said the rules for choosing a cooler . You can buy one of them .The reviews on net can help you for best choise.BUt v8 is a good proven cooler because the more surface that has and material and big fan.although i didnt have another choice in IRAN.You may find so better coolers.
the fluid mechanic rules say that the surface-material-shape of heat sinks and temperature-velocity-amount of air that moves on the heat sinks are the parameters of a heat sink.
i have a bad experience.In my old case with P4 3 GHZ i bought a good cooler from THERMALTAKE .But the fans is rotating very much and made noise. There was some truth that i didnt mentioned.
The cpu is produce a lot of heat ( more than phenom) and the fan is 10 cmm i think . I replaced the fan with a 12 cmm fan but the system in loads crashed. The heat sink designed for such a fan and it must rotate very much to cool cpu .12 cm fans cant go beyond 2000 rpm i think and this amount of air wasnt enough for cooling.
3- you have a lot of wind in your case!!. I dont know that greater fan than 12 cm is safe because they use more current .But 8 and 12 cm fans works very well with onboard ports and SPEEDFAN program.
After all cooling and making the pc make less noise is a long story .You must have a target . There is a limit that you cant go beyond that so i think you must have a plan and use your money and time on it.
For my new system i had a dream: most powerful-silent-upgradable system so i choosed these parts:
POWER=CM SILENT PRO- for the design and big fan that they have.
CPU=ATHLON II 635 -I knew that phenom is very powerful but make more heat so i used this cpu and have plan for upgrading with a 6 core cpu.
VGA= 1-GIGABYTE 9800GT SILENT
2-ZOTAC 9800GT SYNERGY
choosing a gpu was very hard. 9800gt silent was the most powerful silent cpu that i could buy. but for future i bought a zotac. because it has a single cooler and dosnt occupy a PCI slot that i need.
you may say why you dont buy another 9800 silent? because this card is warm in loads and i had a fear two of them in a case may harm them. I count on HYBRID SLI technology that could shut down the second card but it is not working and i am a little disappoint .
two 9800gt in sli have as power as a GTS 270 in reviews.
CPU COOLER=TUNIQ TOWER EXTREM- According to my counts cooler was silent in ideal but in loads it was noisy so i replaced that
MOBO=NF980-G65-It uses the last chipset from nvidia with sli enabled and ddr3 and phenomii x6 support. (The mobo is hot. According to some reviews it is cooler than AMD chipset motherboards and faster but i hope it was cooler)
Good luck

What is the correct way to upgrade 5.0.4 to 5.1 Universal?

I just received Final Cut Studio Universal, and I have Final Cut Pro 5.0.4 installed what is the correct way to upgrade all the Final Cut Studio applications? Do install over or delete each application and then reinstall?
As always thanks in advance for reading and replying to my Post,
Sebastian

WHEN I do it, I'm going to archive what's necessary and desirable to keep, erase my hard drive, reinstall Tiger, do the upgrades, then install 5.1 clean and do the upgrades.
Might sound like overkill, but I really love a clean, fast machine and nothing does it better!

Dynamically changing the report path

Is there any way to dynamically change the path where the reports are saved. Teststand 4.1.1
Message Edited by glennjammin on 04-21-2010 03:30 PM

Solved!
Go to Solution.

Yes you can run a VI in the ReportOptions Sequence, add it to the Setup of that sequence. If you dont use FileGlobals.Dated anywhere else then use a Local instead. Just remeber FileGlobals are only global to sequences that are contained in a SequenceFile. They are not global across SequenceFile unless you are using the Batch Process Model.
You will probably have to set a number of other parameters up to work with ReportOptions.Directory. The best way to handle this is to setup up you exact conditions statically (ie via the Config | Report Options... menu ). Place a breakpoint in the ReportOptions (use a label if you dont have any steps in the ReportOptions sequence at the moment) and run your Sequence. Remeber to use Test UUTs or Single Pass. You dont have to use your full test sequence just create a simple one step sequence.
When you reach the break point, then you can browse the Parameters.ReportOptions and see what properties are required to ensure your reports are setup correctly.
Hope this helps.

OBIEE 10g AGO Function Dynamically Change the Heading

I created columns in my rpd named Sales Previous Month, Sales 2 months ago and Sales 3 months ago using the AGO Function. This is working fine.
My problem is when displaying these headings the users would like to see the Month Name instead of the Headings I created. For example if looking at a report for January the users would like to see:
Sales Previous Month = December
Sales 2 Months ago = November
Sales 3 Months ago = October
Is there any way to dynamically change the value of the column header to show the name of the month?

Hi SriniVEERAVALLI,
Thanks for the reply. I have found that I might haven't created the relationship between dimension and fact tables correctly.
I initially created the foreign key relationship (instead of creating complex join) in physical diagram between the dimension and fact table. And the relationship type is hence greyed out.
I have deleted the foreign key relationship in physical diagram. Then
1. In physical diagram, create complex join between dimension and fact . The relationship is 'inner' and can't be changed.
2. In Logical table diagram, create foreign key between dimension and fact . The relationship can be changed (inner, outer, etc).
Is this the correct way?
I tried these on two newly created dummy tables and it worked.

Dynamically change the binding of a field

Hi,
I've been looking all over the internet for 2 days to find the answer to my question, but I couldn't get any information on my problem. Here's what i'm trying to do :
Based on a checkbox in my form, I want to export or I don't want to export a field to a XML document.
My checkbox is working properly and I got the Send button with the XML working too. I only need to find a way to dynamically change the binding property of my field. I've read some informations with the ".bind.match", but I can't seem to make it work.
I'm using Windows XP, LiveCycle Designer ES2 v.9.0 and I have to run the form in Reader 8.0.
Thanks alot for your help, it's greatly appreciated.
Jonathan

Hi,
the binding cannot be changed at runtime.
You can use the checkbox to delete the value of the field so the exported xml contains an empty tag.
Or you try to delete the data node of the desired field in the data DOM (xfa.datasets).

XFI Drivers - Whats the correct way

Considering that after I installed my XFI Extreme music card into my PC and installed the drivers from the CD played games, rebooted and it asks me to reinstall the drivers for the multimedia device.
What is the correct way to install drivers for these cards so that you can reboot your computer without it freaking out?
The only way i've been able to successfully keep the XFI installed is by doing these things in order.
Uninstalling the software
Uninstall the drivers via the CD uninstall tool
Cleaning the registry with aggressi've options (JV 6 power tools)
Using Driver Cleaner Pro and removing all creative audio and Creative audio lite files.
turning the machine off and moving the Sound blaster card to another PCI slot.
Turning back on and using the drivers off the CD.
If i use any other drivers, the Web update 2 or Beta 3, the card will not install.
this is on this system:
AMD Barton CPU 2500+
ASUS A7n8X-x motherboard 00 bios rev
WD800 80 GB hard dri've
Nvidia Geforce 6600 GT vid-card
GB IBM ram

Well this is a strange problem... So what you are essentially saying, is that Windows doen't keep the the records of your newly installed hardware... Or the hardware may be assigned to new resources after restart, which might cause the Installation to commence.
The 2nd can happen pretty often on an ACPI System, or if you change the "Plug and Play OS" section in your BIOS Setup. But even if this happens, Windows should have still kept the Installation Information in its registry, so it wouldn't bother you searching for the drivers.
So I believe it has to lie with your Windows installation...
What exactly do you mean with "the card will not install" with the newer drivers? Are you getting an error message?
Have you tried the?infamous manual installation? (Extract your downloaded drivers, then go to the \Drivers subfolder and execute Setup from there. Select the "...Creative shared files" option.)

[JSF 1.2] - Role Based Web Application: Whats the correct way of doing it?

Hello,
i have a web application that in some pages is role based. I have two database tables, Role and Permissions. Role can have 1..N Permissions and vice versa.
In one page i need to render some forms depending on user role.
What is the best approach to this?
1. I have a sessionBean and on login load all the permissions (it's less secure but faster) based on user role;
2. Everytime i use rendered="#{sessionBean.checkPermissions['can-create']}" i query the database. This checkPermissions gets the user role and retrieve all permissions of that user on demand;
The first option is faster but while the user is logged if permissions changes we might have problems.
The second, if i user 3 rendered attributes i do 3 queries to the database.
Is rendered attribute the correct implementation?
Regards.

Yes, the rendered attribute is the correct way to accomplish this.
As to the question of caching the result or querying the database each time, that is something that needs to be answered on an application by application basis.

I have a macbook air late 2010 and keep getting a warning that my hard drive is full and to delete things so I purchased a external hard drive (1TB) but I'm just not sure what the correct way to transfer and store files to the external drive is. First MAC

I purchased a macbook air about 5 months ago and lately i keep recieving a warning that the hard drive or disk is full and that I will need to move items to trash in order to free up space on it. I purchased a external hard drive 1 TB but I'm very new to mac and ios and unsure as to how I'm suppose to transfer my files (video, pics, music etc.) from my mac over to the external hard drive in the correct way so I won't end up deleting them permenately or screwing anything up with my mac as far as the applications and programs being able to run. Am I supposed to just copy to the external hard drive and then move to and empty the trash? That's pretty much all I could come up with, but then what if i need or want to access that file again at a later time. Also, I have an i Phone and i pad so with i cloud it automatically syncs all my purcheses and if i delete something from itunes on my mac it deletes from my ipad.
I'd appreciate any kind of input i think im just a little lost here. I have to say i love my Mac and wouldn't trade it for anything (except maybe a macbook pro w/more memory)... Is there something I'm missing???

To free up hard drive space the best bet is to move data files that you don't need access to all the time. Likely candidates are music, video, and photos. Things like word processing and spreadsheet files can also be moved but they tend not to be very large and so don't free up much space. The problem with moving the above mentioned files is that iTunes and iPhoto need to know where the files are stored.
Here's an article explaining how to move the iTunes folder. You can move the iPhoto library using the Finder but there is a slight complication. Start iPhoto, open the Preferences and click on the Advanced tab. The first option is "Copy items to the iPhoto Library". If this option is checked, copy the iPhoto library to your external folder (drag it from the Pictures folder to your external drive) and then delete it from your Picture folder. If this option is not checked, it is a bit more complicated and we'll need to talk a bit.

What is the correct way to add styling to drag-and-drop created calendars?

I have a working instance of a rich client calendar. I generated the view with the required fields (start, stop, provider, ...), put it into the App Module, and dragged it onto a JSF page to create a calendar.
Next I created an activityScope object in a class called CalendarBean (no inheritance)
Class CalendarBean()
private HashMap<Set<String>, InstanceStyles> activityColorMap;
+..+
+public CalendarBean() {+
super();
activityColorMap = new HashMap<Set<String>, InstanceStyles>();
HashSet setEd = new HashSet<String>();
HashSet setLen = new HashSet<String>();
setEd.add("Work");
setLen.add("Home");
activityColorMap.put(setEd, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.ORANGE));
activityColorMap.put(setLen, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.RED));
+}+
+}+
Next, I linked this up as a backing bean and associated the ActivityStyles of CalendarBean to it:
+#{backingBeanScope.calendarBean.activityColorMap}+
I populated some records in the database with properties "Work" and "Ed', but they show default blue.
As I understand it, I need to do something with the getTags() method of the underlying CalendarActivity class, but I'm not quite sure how to do that.
Took a stab at creating a class, CalendarActivityBean, that extended CalendarActivity, and pointed all the CalendarActivity references I had to the new class, but it didn't seem to fire (in debug), and I got into trouble, when inserting records, with
public void calendarActivityListener(CalendarActivityEvent calendarActivityEvent) {
currActivity = (CalendarActivityBean) calendarActivityEvent.getCalendarActivity();
being an illegal cast
What is the correct way to add provider-based styling to drag-and-drop create calendars?
Ed Schechter

A colleague of mine was kind enough to solve this:
The calendar has ActivityStyles property = #{calendarBean.activityStyles}
CalendarBean looks something like this:
package com.hub.appointmentscheduler.ui.schedule;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Set;
import oracle.adf.view.rich.util.CalendarActivityRamp;
import oracle.adf.view.rich.util.InstanceStyles;
+public class CalendarBean {+
private HashMap activityStyles;
private String dummy;
+public CalendarBean() {+
+// Define colors+
activityStyles = new HashMap<Set<String>, InstanceStyles>();
HashSet setPending = new HashSet<String>();
HashSet setArrived = new HashSet<String>();
HashSet setApproved = new HashSet<String>();
HashSet setCompleted = new HashSet<String>();
setApproved.add("APPROVED");
setPending.add("PENDING");
setArrived.add("ARRIVED");
setCompleted.add("COMPLETED");
activityStyles.put(setApproved, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.GREEN));
activityStyles.put(setPending, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.ORANGE));
activityStyles.put(setArrived, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.PLUM));
activityStyles.put(setCompleted, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.LAVENDAR));
+}+
+public void setactivityStyles(HashMap activityStyles) {+
this.activityStyles = activityStyles;
+}+
+public HashMap getactivityStyles() {+
return activityStyles;
+}+
+}+
Now, go into the Bindings tab on the calendar page, double click the calendar binding, and specify the column you've defined as the calendar's Provider in the Tags dropdown.
Should show colors.

1.4.2 - What is the correct way to format output in the java.io.PrintStream

With Java 1.4.2:
What is the correct way to format output in the java.io.PrintStream?
The following is incorrect, even though it is still used in the The JavaTM Tutorial at: http://java.sun.com/docs/books/tutorial/essential/
System.out.formatThis returns "cannot resolve the method 'format'"
Any detailed suggestions or information is greatly appreciated.

The following is incorrect, even though it is still
used in the The JavaTM Tutorial at:
http://java.sun.com/docs/books/tutorial/essential/
The whole format thing has been introduced in 1.5. The tutorial also states it's been "updated to 1.5.".
That's all I've got to say for I don't know how you can format a PrintWriter, let alone a PrintStream, prior to 1.5. I'm not really sure there is any way. Any "legacy way", that is. There almost certainly are third-party API which achieve similar results.
