problem when class from Java Import-compilation error

Hi all
I made a java class that has methods to return the height and width of the screen.
--------------------------------------------------------------------------------------------------
Tarek package;
to import java.awt.Dimension;
import java.awt.Toolkit;

public class screen
{
Dimension dim.
public Screen()
{
Dim = Toolkit.getDefaultToolkit () .getScreenSize ();
}
public double getWidth()
{
Double w = dim.getWidth ();
Return w;
}
public double getHeight()
{
Double h = dim.getHeight ();
return h;
}
}
-------------------------------------------------------------
I made the 'screen.jar' jar file and make it ready to be used in the form builder
I opened the form builder and make import java class (program > import java class > choose the class anc click import)
The class now imported correctly and the PL/SQL package body is:
-------------------------------------------------------------
PACKAGE screen / * tarek. Screen * / IS

--
-DO NOT EDIT THIS FILE - it is machine generated!
--


Constructor for signature (V)
New FUNCTION RETURN ORA_JAVA. JOBJECT;

-Method: getHeight () D
FUNCTION getHeight)
obj ORA_JAVA. JOBJECT RETURN NUMBER);

-Method: getWidth () D
FUNCTION getWidth)
obj ORA_JAVA. JOBJECT RETURN NUMBER);

END;
---------------------------------------------------------------------
Now, I did a button on the form and I WRITE THIS CODE TO CALL THE CATEGORY on when_button_pressed
----------------------------------
DECLARE
vScreen_Class ORA_JAVA. JOBJECT;
BEGIN
vScreen_Class: = SCREEN. NEW;
END;
---------------------------------------
My problem is that I compile error
error 306 AT LINE 5, COLUMN 25
a wrong number or types of argument in the call to the 'NEW '.

I don't know what the reason for this compilation error?
Is this because the method in java return "data type double' in return 'datatype number' oracle
Help, please

The SCREEN is a reserved word (this is a constant), then try renaming your package/pl at JScreen, then it will work.

    Sorry for the long delay before responding. Unfortunately, there is a bug where forum e-mail notifications stop working from time to time.

    This line shows the problem:

    Caused by: java.io.IOException: could not obtain lock for E:\data\database/je.info

    je.info.N files contain monitoring logging. I use java.util.logging for this. The N at the end of the file name is assigned by java.util.logging and it runs from 0 to 9. What can happen is that you ran the names of the log files, or maybe the file is not closed properly (sounds like you're on Windows). Try to move all the files in je.info. * the environment directory and then open again the environment.

    Hi Verisetti,

    Have you installed security software after formatting windows?

    If so, you can uninstall the security software temporarily and check if you receive the access violation error.

    If the uninstallation of security software solves the problem, you may need to configure the settings of the software of safety accordingly. Please contact the software vendor for assistance in this regard.

    Note: Make sure that you install the security software after the trial.

    What about Windows vista product ID, you can try to validate Windows and check if it helps.

    For more information, see the following articles:

    What is the validation, and how does it work?

  • Problem when booting from USB and bootable DVD

    I tried to boot from a bootable DVD to try Linux and install it. So pressing F9 to select the boot device, so I chose DVD ROM drive But it still does not start.

    Note: It starts on the first run. When I restart the PC and try again to start from the DVD, it jumps the DVD playback. Same thing happens with the USB key. I tried all USB ports.

    Another time all USB ports too and this pen drive work well and the DVD. Don't know what the problem is.

    Please tell me is there any problem with the BIOS?

    Thank you.

  • Problem when upgrading from windows 7 to windows 10

    When I installed the free update for windows 10 on my win 7, he asked me to automatically install updates for her but I clicked on update later, I thought it was a minor update but my windows 10 of the language pack installation package has disappeared...

    My Installer went up 83% and something, then it restarted and when it started showed 0xc000000f problem and tells me to insert a disk installation and repair my computer, I don't have any drive to win 10 or win 7 disc, but I do had win 8 disk, so I booted my pc with him... and windows 8 works... bt every time my pc displays the message to choose an operating system and the os are windows 8 and another is the clumsy windows installation, when I click on windows 8 it starts normally but when I click on windows installation this old problem 0xc000000f takes place,... What should I do to get back on my windows 7? and I got win 7 in the recovery partition, the icon of recovery showed and I've never touched bt after that when I access win 8 and then access the recovery partition, is to show that the same amount of data, which is full of partition bt icon does not appear and nor my windows recovery tool 8 helps me to do or to recover?

    Hello

    If you can start with 8 Win Media and select REPAIR installation screen, you will get Repair Options...

    Select troubleshooting, then advanced... You MIGHT have an option for going back to a previous operating system...

    Another thing on the start menu...

    If you go into MSCONFIG... The STARTUP tab, you will probably see a list of which appears when you start your machine... There will be options to select one as the default...

    I delete anything again, until get you a better idea as to what is still usable.

  • Stange button problems when exporting from Fireworks

    First of all thanks for the help of others on button issues I've had.

    I created a button with popup menu of fireworks, I saw the button and preview in fireworks gives an overview of the pop-up menu in the excatly the correct position, however when I insert the Fireworks HTML code in a Table in Dreamweaver and previsualisez in IE the table jumps to the top of the button, I tried to move the start position in Fireworks then export again, but the problem is still there. Under the button in the table after insert Dreamweaver adds what looks like a Golden Shield opportunity / anchor with my pop-up Description of the menu, I guess it's the pop-up of the menu Description, this is what causes the problem. ?.

    I enclose the HTML for the experts that I know are hiding on this forum.

    Becomes very frustarted now. !. I'm so close to make the Pop up menu bar done and people here said it does not work, once this fix is over I'm ready.

    Hope someone can help me.

  • folds of 7612-printer Officejet 11 x 17 Paper 3 "from the top when printing from my computer

    Name of product-Officejet 7612.  Operating system - OS X - Yosemite (10.10.1) for my desktop and OS X (10.6.8) for my laptop.  Problem when printing from a Mac machine in the Officejet 7612 on paper 11 x 17, it will always create a mountain/valley fold all the way across the top of the sheet about 3 "from the top.  The folds will be straight through.  Whether it's origami, it would be the perfect machine.

    When I print from the control panel of the printer (for example a printing of print quality, or something www.hpeprint.com like news or some other print it will print properly with no fold either.)

    It seems as if this in case of instructions from the computer to the printer to print, he gets in a hurry to get the document creating the folds, but when it comes to the machine itself, he picks up the paper gently.

    Any thoughts?

    Hi @Bodija ,

    I see that you have problems when printing on 11 x 17 size paper of Yosemite, but you can print the thin material and ePrint test page. I will definitely do my best to help you.

    When you print from the computer, you can print on letter-sized paper or are you just had the problem with the paper 11 x 17?

    Here is a document to clean the rolls of paper to see if that will help.

    A "Paper jam" error displays on the e-all-in-one printer large Format HP Officejet series 7610.

    Go to Solution 5: clean the rolls of paper.

    Using the full feature software drivers?

    Series 7610 Wide Format e-all-in-one-HP Officejet full feature software and drivers.

    Check the name of the driver that is installed by the printer. Make sure that it shows just the name of the printer.
    Click on the Apple menu, click System Preferences. Click on Printers & Scanners, highlight the name of the printer on the left side and right side of the screen it should show the name of the printer. (Officejet 7612)

    If the full name of the printer is not correctly, delete and add the printer name back from the list. Click on the sign - to remove the driver and then click on the + sign to add the driver might have to drop-down list to select the name of the printer to add a click.

    If you still have problems with it is software related, try the following steps.

    Fix permissions of the drive on the Mac:

    Close all applications.

    In the Apple menu, click OK, click Applications, and then click utilities.

    Double-click disk utility.

    Highlight your hard drive / partition on the left.

    Click on check and then repair disk permissions.

    Restart the computer...

    Reset the printing system:

    Note: This will remove all printers in the print and Fax/Scan, any printer deleted can be re-added later by clicking the sign plus (+) symbol.

    Click on the Apple icon and then click on System Preferences.

    Click on Printers & Scanners.

    Make a right click (or Ctrl + click) in the left white side panel, and then click Reset printing system.

    Click OK to confirm the reset.

    Type the name and the correct password.

    Click OK to reset the printing system.

    Then click on the sign to add the driver, highlight the printer +. (you may need to click the drop down menu to select the name of the printer) Then click the Add button.

    Try to print again.

    How the name of the printer was placed in printers and Scanners?

    If you need help, let me know.

    Have a wonderful day!
    Thank you.

  • problem creating oscustomisationspec from the command line

    Hello

    I have a problem when you create or modify a command line oscustomisationspec

    If I change the administrator password or domain password I have a problem when you use the customisationspec

    error is cannot decrypt the password

    the public key in the specification does not match the public key of vcenter...

    When I create this oscustomisationspec of my xp machine I have no problem

    When I create my Management Server I have the problem

    and when I create it from the vcenter itself I have the question too

    I don't understand why I'm using the right button of my computer and not a server

    If I create the customspec of the client vsphere vcenter or on the management server, it works well

    Another thing

    If I export customization of my computer the plain text for the password value is false

    If I export the customization of the server the value of plaintexst is true

    my machine is xp

    the waiters are win2003 and win2008

    can anyone help?

    Hello, DanielSoares-

    This could be linked to the bug referenced in the thread to the http://communities.vmware.com/thread/297748.  Here, broedi and vitalibaruh done by are the property of plain text for passwords in the spec is set to $false instead of $true when.  They discuss this issue when using New-OSCustomizationSpec to clone an OSCustomizationSpec, but I got the same behavior you describe when you create a new persistent by using New-OSCustomizationSpecOSCustomizationSpec.

    In the thread (the post to http://communities.vmware.com/thread/297748?start=18), vitalibaruh (from the team of PowerCLI) mentions that he's filed a bug for this behavior.

    So for now, the solution seems to be to create the OSCustomzationSpec via the vSphere client and, if you want to work with a copy of the spec (to add/modify credentials, for example), use the API to clone the spec (via the DuplicateCustomizationSpec() method) and then use Set-OSCustomizationSpec to make changes to the clone.  I've posted an excerpt on the use of this method twice in this same thread.

    Is not ideal, but that market.  I hope this helps.

  • Code received the error 80004005 When you try to import photos and video from the camera in Windows Live Photo Gallery.

    Spent several hours in technical support with gun tries to resolve to not be able to download pictures from the camera to my Win XP computer.   Usually the computer detects the camera and demand "How would you import pictures?" and the list of shows in one window.   We don't get any list in this window, but only managed to fill the window briefly for WLPG to detect the photos and video, but when we went to import, we received the 8004005 error.   Thereafter, things have regressed, and we're back to not get any answer computer saying that it detects pictures or video - nothing.   But back to square one.

    There are two issues here - likely related: unable to import photos and videos and the 80004005 error.   Who came first and is there cause and effect here, and which way should we go?  Inquiring minds want to know - and being able to import photos and video of the camera Canon Powershot A3100IS again.

    After hours Technical Support Canon was completely blocked and indicated that it was probably an OS problem with my computer.

    Thanks for all your great suggestions.    I finally solve the problem, but I don't know exactly what fixed it.   I ended up running CCleaner (latest version) and make a 'windows', 'applications' and cleaning of "registry".   This needed a re-boot, and when I rebooted, it's when I could finally download the pictures from the camera.    Not exactly what fixed the problem, but there may be here spirits who may be able to say, ' Yes, with blah, blah, blah, you did...» ».

    As far as I know that is a lot of sterile technical support hours and re - install the software and then, finally, runing CCleaner paid off.    I will record your information in case I need it in the future... Thanks again.
