Intermittent ClassNotFoundException when using the Attach API
I'm trying to load an agent dynamically and I'm getting occasional an occasional CNFE. It doesn't make any sense because I'll run once and it'll work. Then I'll turn around and run the same scenario and it fails. In both instances I KNOW that the class is indeed in the classpath. Any ideas what I may want to look at?
Thanks,
Rick

I would expect a missing parent class, or an exception from a static block happen every time.
Nope. For example if a static block was attempting a socket connection and the timing on that was bordeline such that timeouts occurred sometimes and not others.
Or it reads a file. And something intermittently messes up the format of the file.
I'm running a single threaded application(so this isn't a threading issue) that fails every 3-4 runs. Any other ideas?You are not running the Sun VM then. It always has multiple threads.

Intermittent error when using the Disco Viewer client
Hi, I have a user receiving the following intermittent error when using the Discoverer Viewer client:
“The application encountered an invalid state.
- Discoverer Beans XML Exception. Method: findNode Class: XMLUtils Error: Cannot find parent node. Parent element does not exist in XML document, looking for database_account/eul
OracleBI Discoverer Viewer was unable to find the necessary data for displaying the results of this event. Please correct any errors and try again.”
Any idea what this might be? Any help or direction would be very much appreciated! Thank you!Hello
Is this related to a single machine or common to a single report or is it purely random?
I did a search on your behalf and came up with nothing related to this error. You may therefore need to raise the problem with Oracle Support.
Just out of curiosity which version of Discoverer are you using?

Error when using the Attach to Email... Feature
I currently using Adobe Reader 8.0 as well as Adobe Acrobat Professional 8.0. Whenever I try to use the Attach to Email... feature I get a debugging error. It always brings up the Visual Studioi Just-In-Time Debugger. It will create the email, but it will not attach the document at all. I've also tried this on a computer that only has Adobe Reader 8.0 on it. When using that computer, it always gives me an error message naming the .dll file gwmlt1.dll.
I can't seem to find what the issue is with this feature. Any help would be very much appreciated.
Also, We are using Windows XP on all of our computers here. If anyone needs any additional information about this, just let me know.
Thanks in advance for any help.
TPrimegwmlt1.dll is something to do with GroupWise (your e-mail system)
Maybe Novell can help.

Hi,
I've seen thousands of posts about Bluetooth connection issues and interference and stutter/lag for both the Magic Mouse and Trackpad (affecting both Mac OS X and Windows under Boot Camp) but my problem is different.
To summarise my setup, I use:
- Retina MacBook Pro (lid closed or open, doesn't make a difference to this problem)
- Thunderbolt Display
- Wireless Keyboard
- Magic Trackpad (have also tried a Magic Mouse and experience similar issues to the Trackpad)
And in Mac OS X, everything works perfectly. The keyboard and trackpad work smoothly when I'm 6-7 metres from the machine, whether or not the laptop lid is open or closed, and whether or not the Thunderbold Display is connected.
But on to my problem: the bluetooth connection is incredibly unreliable/intermittent when in Windows (I run Windows 7 64-bit and Boot Camp 4.0, and got both devices connected without any trouble via Bluetooth).
But during usage, the cursor stutters/lags frequently, and tap to click (when enabled) seems to get triggered by mistake all the time (even when I'm not touching the Trackpad or even at the computer, clicks get registered).
The Wireless Keyboard is perfect, and works well 5 metres from the machine. The Mouse and Trackpad, though, don't even work reliably when they are 6 inches from the machine. The built-in trackpad on the laptop works perfectly too, in Windows and Mac.
I spent a week assuming I was suffering from Bluetooth interference, so I tried:
- using the laptop with the lid open
- removing the Thunderbolt display completely and trying the Magic Trackpad
- repositioning items on my desk
- disabling wifi
All of these adjustments made minor differences to how good/bad the Trackpad was, but none came close to fixing the problem or making it work as smoothly as under Mac OS X. It was only after doing all of this that I realised perhaps it was just a Apple driver for Windows issue, so I booted into Mac OS X and tested everything out, and sure enough, it's all perfect. But back into Windows, the Trackpad doesn't work reliably at all.
Obviously, the hardware is not at fault, and I assume the signal strength doesn't vary between operating system (why would it?) so I'm left believing this must be a driver issue. The TrackPad and Magic Mouse drivers have been out for a couple of years, so I'm surprised they can still be this bad. I tried both the latest driver from Boot Camp 4.0 (3.2.0.0) for the Trackpad, and also the older one from Boot Camp 3.2 (3.1.0.7) and both are equally bad for me.
So my question is: has anybody else struggled with using the Trackpad (or Magic Mouse) with Boot Camp 4.0 and Windows 7 64-bit, whilst finding it to be perfect under Mac OS? I haven't found many posts complaining about the Windows driver, which is why I assumed it was an interference issue. But I'm almost sure it isn't, having spent 2 weeks investigating.
Any thoughts/suggestions/answers much appreciated!
KyleSOLVED!
After much testing, I have found the cause of lagging/jumpiness on the Bluetooth Magic Mouse and Magic TrackPad in Boot Camp. Hopefully this will help others:
The drivers for the Broadcom 802.11n Wireless Adapter have a setting called "Bluetooth Collaboration" that is Disabled by default. Enabling this option removes the problem instantly. My Magic Trackpad now works flawlessly, even if I stand 6 metres from the machine. It now works just as well as under Mac OS. The setting can be found under:
Control Panel > Device Manager > Network Adapters > Broadcom 802.11n Network Adapter (right click and choose "Properties". Under the "Advanced" tab, highlight the setting named "Bluetooth Collaboration", then change it to Enable. Then click OK.
I narrowed the problem down to the wireless card by disabling ALL startup services and processes for Windows, then re-enabling one by one. As soon as I enabled the Windows Wireless Service, the problem came back. Similarly, disabling the Wireless Card inside the Network and Sharing Center (or Device Manager) removes the problem. This led me to believe it must be a driver issue with the wireless card, since the problem didn't occur with the Magic TrackPad under Mac OS, or on my mother's Windows 7 64-bit computer. So when I went into the Driver Properties to check for an update, I found this setting about Bluetooth Collaboration.
I really hope this helps others trying to use Bluetooth devices under Boot Camp. All Apple notebooks use the Broadcom card (and have done for years), so this driver is installed for almost anybody using Boot Camp on an Apple notebook. I'd assume this problem would affect anybody using Boot Camp + wifi + a Bluetooth device.

Programatically detecting uniqueness constraint violations when using Direct Path API
I'm developing an application that bulk loads data into the
database using the DirectPath API.
According to the DirectPath API documentation uniqueness
constraints must be disabled prior to importing data using the
DirectPath API, then the constraints must be re-enabled.
If duplicate data is inserted when the constraints are disabled,
enabling the constraints results in the constraint's underlying
index being left in an "unusable" state.
The SQL*Loader tool (which also uses the DirectPath API) somehow
manages to deal with this.
It can successfully detect which data causes the constraint
violation, and politely writes the offending data to a bad rows
file.
If SQL*Loader also uses the DirectPath API - how does it detect
which data causes a constraint violation.
The mere fact that SQL*Loader can do this in DirectPath mode,
shows that it is possible.
Any ideas how to detect which data causes a constraint violation
when using the DirectPath API ?

When using the iphone 6 Plus. I use iMessage and then attach a photo or take a photo... the app does not show the camera fully or even to attach a photo does not work. I have about 8-9000 phones and like 10 short videos in there but it is incredibly slow and almost unable. I have the 128GB iPhone 6 Plus with 46 gb still available. I think this should not be so slow with so much memory still available. Please help. I am using 8.1.2. Yes I have set up the phone as a new phone. Apple store even reformatted this iphone 6 plus 2 months ago but it is still terribly slow Thanks
Hey Bender1031,
Thanks for the question, I can definitely understand how frustrating this issue may be with a brand new phone. Great troubleshooting so far by already attempting a restart and reset. If the issue persists, let’s try restoring your device and updating to the latest software (iOS 8.0.2):
Back up and restore your iOS device with iCloud or iTunes
http://support.apple.com/kb/HT1766
iOS: How to back up your data and set up your device as a new device
http://support.apple.com/kb/HT4137
After erasing and setting up as a new device, your device is now in a factory configuration. Test to determine if erasing and setting up as a new device resolved the issue. Content on the device may have caused unexpected behavior.
- If the issue is still present, you may want to contact Apple Support.
- If the issue is now resolved, sync one type of content at a time back to the device. For example, if you had an issue playing music, add songs from iTunes and confirm they will play. If your contacts weren't loading successfully, add the contacts back. After each sync, test to see if the issue has returned.
Thanks,

Creating junit test cases using the reflection API
In order to use the reflection API to get information about a *.java file's class name and methods, I need to compile the *.java file first, and then get info through the *.class file. Am I right?
Eclipse, the Java IDE, can create junit test cases for java files the user selects right after the *.java files have been created, and even before the *.java files have been compiled by the user. I guess Eclipse internally compiles the java files before creating JUnit test cases for them. Does anyone know about it? Thanks.Let me explain my problem in more details.
Given any java source tree, my program is supposed to create junit test cases for each class using java reflection. My approach is to scan through the source tree to keep the list of classes available, then compile all the java files in the given source tree, then do Class.forName() to load them to get their methods... Obviously I don't know what classes I will have at compilation time. I create a temp_classes directory as the output directory for the given source tree java files, and I add temp_classes to my classpath when I strart up my own program. However, that won't work..
D:\eclipse\workspace\cmpe271_hw4\classes>java -classpath ..\classes;..\temp_classes Test
javac -classpath .\temp_classes; -d .\temp_classes @temp_classes\javalist.txt

PDF: Unable to print a document as PDF from APEX when using the BI Publishe
Hi,
From an APEX application, I am unable to print a document in a PDF format when using the Oracle BI Publisher.\
Here is the configuration:
1) Server A is W2K3 and hosts the Oracle BI Publisher server, with IP address ip01.
2) Server B is a OEL5.2 and hosts the database server of the APEX application, with IP address ip02.
3) Machine C is a W7 desktop from which through an URL both the APEX applicationn and the BI server are accessed, with IP address ip03.
4) The APEX application is configured with the following to use the Oracle BI Publisher:
- Printer server: Advanced (requires Oracle BI Publisher)
- Printer server protocol: HTTP
- Printer server host address: ip01
- Printer server port: 9704
- Printer server script: /xmlpserver/convert
- Network services are enabled (at least I did get any warning/error message)
From C, I access the the APEX application through its URL, if I try to download a page by selecting PDF in the download section of the interative report section for that page, I am unable to open if and get the error:
<file>. pdf file can not be opened because the file type is not supported or because it is damaged (because, for example as an e-mail attachment is not sent and correctly decoded)
Yet, still from C, I am able to open any other PDF document.
The same way, still from C, acessing the APEX application through its URL, I have a query report defined with a PDF output format. Then, when I test the report (Test Report in the Report query) for that query, I get the error:
ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified.
At first sight this could be a wong entry in the priinter configuration for APEX. But with this address, through the URL I can log in to the Oracle BI Publisher server.
Does someone has an idea what the problem could be?
Thanks for any tips.How are you trying to print to pdf?
Don't go via PostScript or Acrobat Distiller, which are old deprecated technology.
You use:
Menu > File > Print > PDF (button bottom left) > Save as PDF…

How to add image in virtual dir / i/ 11g when using the embedded gateway
Hi,
Does somebody knows how to 'simple' import a file or directory
into the /images/ or /i/ directory created by APEX without tricks like in How I added a new image to APEX in 11g when using the embedded gateway.
when using Database 11g with the embedded gateway. with webdav of ftp.
When I use the url http://localhost/images
I need to logon.
There is not 1 username/password that I can use. I tried all.
When I try http://localhost/i/16admin.gif then the gif is shown.
I must be something with ACL's or DBMS_EPG or maybe the default port 80 that I use?

after updating my Macbook Pro retina display to os x yosemite 10.10.2, the mause and track pad locks, and do not respond especially when using the Mac for a long period, please help, how can I solve this, I do not like feel like in windows, so I paid good money for this mack, I feel calm
Hi Buterem,
I'm sorry to hear you are having issues with your MacBook Pro since your recent Yosemite update. I also apologize, I'm a bit unclear on the exact nature of the issue you are describing. If you are having intermittent but persistent responsiveness issues with your mouse or trackpad, you may want to try using Activity Monitor to see if these incidents correspond to occupied system resources, especially system memory or CPU. You may find the following article helpful:
How to use Activity Monitor - Apple Support
If the entire system hangs or locks up (for example, if the system clock freezes and stops counting up), you may also be experiencing some variety of Kernel Panic. If that is the case, you may also find this article useful:

FileNotFoundException when using the Help.addBook method
Hi,
I tried to use the following code:
HelpSet helpSet = new HelpSet(myUrl);
Help help = new Help();
help.addBook(helpSet);
However, when trying to launch my application, a "FileNotFoundException: c:\Documents%20and%20Settings\...\myToc.xml" is thrown !
This problem occurs when using the JDK 1.4 (it does not seem to depend on the version of Oracle Help for Java: I tried to use successively 4.1.16, 4.1.17 and 4.2 versions !).
When developping my own application, I encountered a similar problem and found that it was related to a change in the java API. More precisely, prior to JDK 1.4 beta, getClass().getResource("myFile").getFile() would return "/c:/Documents and Settings/myFile" which could be used to read "myFile". But in JDK 1.4 beta, it returns a location that has spaces translated into %20 characters ("/c:/Documents%20and%20Settings/myFile") which cannot be used as a valid file name in java.io.File or java.io.FileInputStream classes.
Could you help me ?

Hi,
I`m getting error message like "None of the apps in your project can be activated in the target. The manifest file of one or more apps contain API sets or Office applications that are not supported by
the target Office client. To debug those apps, update manifest files to exclude any unsupported API sets or Office applications, and then start the project again. Alternatively, you can debug your apps by using Office 365 as a target." when when
updating the JavaScript API for Office and manifest schema files in your Visual Studio project from version 1.0 to 1.1 in manifest file though i have added host elements.
any help in this regard is highly appreciated
Thanks,
Santosh SutarHi Satosh Sutar,
Based on the description, you got the error message when you update the apps from version 1.0 to 1.1.
From the error message, it seems the menifest include some settings no allowed in the new version. Would you mind sharing more detail about how you update the project?
And here is an article about updating apps for Office and menifest schema files in the project for your reference:
How to: Update the JavaScript API for Office and manifest schema files in your Visual Studio project from version 1.0 to 1.1

Hello to all,
this is some sort of theoretical question.
I been reading the JMS documentation for a while.
1.I could not understand what this statement means :
>
This section describes the ways in which using the JMS API in enterprise bean applications or web applications differs from using it in application clients.
What a developer is allowed to do is different depending on whether they are writing code to run in a container or not. The container already provides lots of services so some code you would write for outside a container is not needed when you write for a container. There are APIs that you are not allowed for in container code if you want to adhere to the spec.

2. What is the difference to use the JMS in java EE web orEJB container and application client ?
Thanks.Read more of that document to find out the differences. Application components in Web/EJBs must not create more than one active session per connection while application clients are allowed to do so. -
