HELP Create Extenstion using JFrame instead of JPanel (10.1.3 Release 3)
Hi,
I manage to create a custom GUI editor in JDev but if i switch it to JFrame, JDev GUI Designer display nothing but an invinsible frame.
I'm using sample from customeditor in extension sdk
Any ideas ?
Thanks
It seems that you are trying to use a JFrame as the GUI of your custom editor. The JFrame is a heavy weight component (has a real window behind it). In JDeveloper custom editors must not use JFrames or AWT Frames as their root GUIs. The windows of these frames will paint on top of other editors even if they are behind in the component stacking order.

Creating aggregates using abap instead of relying on the interface
Does anyone know how to create aggregates in BW by using abap instead of the habitual dragging and dropping?
Hi dear,
I know there is a report to copy an existing aggregate to a cube to another one (look at OSS note 608814 "Program for copying aggregate definitions")...
Maybe this can be useful...

Help creating an instance of an internal JPanel method?
I hope my terminology for this question is correct but I will describe my problem also.
I have several class files but the 2 classes relating to my problem are Main.java and MapNavigation.java
Main.java is my application JFrame to which I add other JPanels.
I would like to add an internal JPanel method from MapNavigation.java to main but do not know how to reference it?
How would I reference the JPanel method in MapNavigation in order to add it to my GUI in Main?
public class MapNavigation
public class ControlPanel extends JPanel implements ActionListener
public ControlPanel()
class Main extends JFrame
public Main()
// I wan't to add ControlPanel from MapNavigation.java here!
}Thanks in advance
I'm very new to java and still have limited knowledge, all of your help is very much appreciated.
DaveHi, I tried your suggestion but I get the error:
C:\Documents and Settings\Dave\Desktop\src>javac Main.java
Main.java:20: cannot find symbol
symbol : class MapNavigation
location: class MapNavigation
MapNavigation.ControlPanel MNCPanel = mapNavigation.new MapNavigation();
^
1 error
what would you suggest to be a better method to my problem as I'm using MapNavigation as a class that extends ViewPlatformAWTBehavior for the controls of my application so therefore cannot add the class directly to my GUI and therefore have to add a method contained in the class.
Thanks in advance

Calling a method on a jFrame from a jPanel that created by the jFrame
Hi all
I can not for the life of me work out how to do this.
Calling a method on a jFrame from a jPanel that created by the jFrame.
I have used this code to set a handle for one jPanel to another.
i.e I can create new jpanel and pass in handles from one to another but not back to the jFrame.
// this is sudo code
private Panel_Top topPanel;
private Menu_Panel menuPanel;
private DataPanel dataPanel;
//create new
topPanel = new Panel_Top();
menuPanel = new Menu_Panel();
dataPanel = new DataPanel();
// add handles from one to another
menuPanel.setDataPanel(dataPanel);
topPanel.setDataPanel(dataPanel);
topPanel.setMenu_Panel(menuPanel);
dataPanel.setMenu_Panel(menuPanel);
// in each class I use this to set
public void setDataPanel(DataPanel dataPanel) {
this.dataPanel = dataPanel;
}But I can not seam to get a handle back to the jFrame that created it.
Please help
as you can see I am trying but no luck so far
Thanksclass Life extends JPanel{
pulic Life( JFrame owner )
owner.doSomething(); // pass the JFrame to the constructor and feel free to use it

Hi guys, need a little help here in creating a Jframe. Its not something I am knowledgeable at all with and I need this done for my Introductory Java class. I have the other parts of the program finished as best as I can get it. I will post the problem and my code so you guys can look at it and maybe help me out. All help is appreciated
Problem:
Congratulations, your fame as a Java programmer is spreading, and you have been hired by Intelecom Group to create a special application. Using multiple classes design an online address book to keep track of the names, addresses, phone numbers, and birthdays of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. This program should load the data from a file, called phoneData.txt.
User Interface: Using JFrame, create a user interface of your design. Remember, unless notified otherwise, ALL input and output will be via this interface.
Functionality: The program should be able to do the following:
a) Search for all of the names and phone numbers by first letter of the last name, (this can be displayed using a message box)
b) Search for a particular person by last name, displaying their phone number, address, and date of birth.
c) Display the names of people whose birthday's are in a given month.
d) Search for a person by their phone number, displaying their name, address, and their relationship (ie. Family, Friend, or Associate

My application was designed based on MVC Architecture. But I made some changes to HMV base on my requirements. Servlet invoke helper classes, helper class uses EJBs to communicate with the database. Jsps also uses EJBs to backtrack the results.
I have two EJBs(Stateless), one Servlet, nearly 70 helperclasses, and nearly 800 jsps. Servlet acts as Controler and all database transactions done through EJBs only. Helper classes are having business logic. Based on the request relevant helper classed is invoked by the Servlet, and all database transactions are done through EJBs. Session scope is 'Page' only.
Now I am planning to use EJBs(for business logic) instead on Helper Classes. But before going to do that I need some clarification regarding Network traffic and for better usage of Container resources.
Please suggest me which method (is Helper classes or Using EJBs) is perferable
1) to get better performance and.
2) for less network traffic
3) for better container resource utilization
I thought if I use EJBs, then the network traffic will increase. Because every time it make a remote call to EJBs.
Please give detailed explanation.
thank you,
sudheer<i>Please suggest me which method (is Helper classes or Using EJBs) is perferable :
1) to get better performance</i>
EJB's have quite a lot of overhead associated with them to support transactions and remoteability. A non-EJB helper class will almost always outperform an EJB. Often considerably. If you plan on making your 70 helper classes EJB's you should expect to see a dramatic decrease in maximum throughput.
<i>2) for less network traffic</i>
There should be no difference. Both architectures will probably make the exact same JDBC calls from the RDBMS's perspective. And since the EJB's and JSP's are co-located there won't be any other additional overhead there either. (You are co-locating your JSP's and EJB's, aren't you?)
<i>3) for better container resource utilization</i>
Again, the EJB version will consume a lot more container resources. -

I have just purchased an iPhone5 and created a new user instead of using my iPhone3 ID. How can I access my previous data?
don't just sign out!
if you simply sign out, the stuff you recently purchased will be an issue in the future when an update comes out for apps or anything else. restore the device as new from itunes then restore from a back if you have one as stated above...or set up as new and use correct apple id. this will ensure you will be using the apple id that you used originally without issues from the new one. -
Can't create Theme using a View - Help
Has anyone created a theme off of a table view?
I'm new to the GIS world. When I try to create a new Theme using a View as my source 'Base Table'. It says that 'the base table <mytableviewname' does not have any sdo_geometry column defined.'
I created the view using PL/SQL developer and it shows the geometry data field named: SHAPE
TABLES
VW_OD_COUNTY
COLUMNS
OBJ - SHAPE
TYPE (Folder)
MDSYS.SDO_GEOMETRY (Yellow cube)
other stuff.....
Anyone have luck using views instead of tables?
Thanks -Joseph-If you have not inserted a record into USER_SDO_GEOM_METADATA for this view that you have created, then you must do that so it is "recognized" by Spatial Advisor and any other application. See the Oracle Spatial Users Guide and Reference for how this is done. Its quite simple.

What is wrong with Firefox ---It will not pull up anything the way it used to --having to use exployer instead ---Help
The catalog of our University will not pull up properly on Firefox but will on internet exployer Why?The #rdn# is a url variable that is pass to this form from
another page. I put it in a hidden filed and originallly used it as
from.rdn. That did not make a difference, so I just used rdn.
The cfoutput to display the rdn, partnumberid,
deliverynumber, totalrows, and row, all display properly. I even
use those in the query anlayzer and the update works.
I will remove the crparam and see if that makes any
difference. This is very frustrating since there are no error
messages and I am led to believe the code works. -
Help to create outlines using javascript in adobe illustrator cs4
Hi,
Please help me to create outlines using javascript in illustrator cs4.
Thanks
KarthikThe textFrame object has a createOutline() method. So if you are wanting to save a version of your file that will not require fonts then loop thru these items in your document… (Loop backwards btw its easier that way) Take a look at the other posts at the top here as others are wanting to do the same thing… If your document is more complex then you may need to iterate all the way though which takes a bit more work…

Creating Weblogic Engine Queues using SAF instead of regular Queues
Hi,
I was just wondering to see if anybody has configured Oracle BPM engine with weblogic using SAF instead of regular queues ? I would like to know the impact. Any comments on Advantages/Disadvantages of this approach is also appreciated
My primary objective for this mode is not lose any process data for lack of access to the underlying resource. I was hoping SAF would queue all the data incase of the resource unavailability and would then update the resource once it is available.
TIA
