• ADF page security - the untold password rule

  - by ankuchak

  I'm kinda new to Oracle ADF. So, in this blog post I'm going to share something with you that I faced (and recovered from) recently. Initially I thought if I should at all put a blog post on this, because it's totally simple. Still, simplicity is a relative term. So without wasting further time, let's kick off.    I was exploring the ADF security aspect to secure a page through html basic authentication. The idea is very simple and the credential store etc. come into picture. But I was not able to run a successful test of this phenomenally simple thing even after trying for over 30 minutes. This is what I did.   I created a simple jsf page and put a panel in it. And I put a simple el to show the current user name.  Next I created a user that I should test with. I named the password as myuser, just to keep it simple. Then I created an enterprise role and mapped the user that I just created. Then I created an application role and mapped the enterprise role to it. Then I mapped the resource, the simple jsf page in this case, to this application role. This way, only users with the given application role can only access this page (as if you didn't know this duh!).  Of course, I had to create the page definition for the page before I could map it to an application role. What else! done! Then I hit the run menu item and it all went well...   Until... I got this message. I put the correct credentials repeatedly 2-3 times. Still I got the same error. Why? I didn't get any error message during the deployment. nope.  Then, as I said before, I spent over 30 minutes trying different things out, things like mapping only the user(not the role) to the page, changing the context root etc. Nothing worked!  Then of course, I bothered to look at the logs and found this. See the first red line. That says it all. So the problem was with that password. The password must have at least one special character and one digit in it. I think I was misled by the missing password hint/rule and the fact that the deployment didn't fail even if the user was not created properly. Well, yes, I agree that I was fool enough not to look at the logs.  Later I changed the password to something like myuser123# . And it worked. I hope it helped.

• how to get wireless to work on my HP Compaq nx6325 Notebook on 12.04

  - by user211487

  When my laptop ran XP, the wireless worked perfectly. Now the only way I get internet is having it wired in my living room - which is MASSIVELY inconvenient for me seeing as my room is outside. I have downloaded the driver from 'Additional Drivers', reset my computer (with difficulty, it also doesn't seem to like turning off, so I have to 'kill' it) and still nothing! I have looked all over the internet trying to find solutions but I just cant seem to get it to work. I have a USB wireless stick but I can't load the driver from the CD. I got this comment on a previous question: "Using either Snaptic Package Manager or Ubuntu's own Software Centre, remove "bcmwl-kernel-source" if it's already installed. Next, search for "firmware-b43-installer” and “b43-fwcutter” and install both. Finally, running Software Sources and checking the Additional Drivers tab you should find Broadcom STA Wireless Driver that you can select, install and on reboot hopefully have wireless working ok..." Which I replied: "Right, so I tried to find/remove "bcmwl-kernel-source" but couldn't find anything. I managed to install both "firmware-b43-installer” and “b43-fwcutter” using terminal, after finding out how it worked. And lastly, I couldn't figure out how to find 'Broadcom STA Wireless Driver' - still no more additional drivers. And my wireless is still not working. My laptop has a button that turns wifi on and off and since I put Ubuntu on it, it hasn't worked. And also, my computer still doesn't seem to restart properly - it just gets stuck on the ubuntu loading screen." - hope that helps, somewhat I am VERY new to Linux, not very technical and in need of help! -Running Ubuntu 12.04 32bit on a HP Compaq nx6325 Notebook Thank you to anyone who replies, its much appreciated

• Linux/OS X dualboot on a Macbook Pro with RAID

  - by GaretJax

  I'd like to install Gentoo Linux on my Macbook Pro by keeping my current OS X installation. I currently have OS X installed on a RAID 0 on two 160GB Intel SSDs and I'd like to create a new partition for Gentoo alongside OS X without losing the RAID setup but, from what I read on the net, Apple's software RAID is poorly (read "not at all") supported: BootCamp refuses to create a windows partition on a RAID volume rEFIt is not able to boot an OS from a software RAID even Apple's recovery partition for Lion can't be created on a RAID volume Is there a way to dual boot my Macbook while keeping the RAID solution?

• How come I cannot make this file executable (chmod permissions)?

  - by bappi48

  I downloaded Android Development Tool for linux (ADT) and placed it in home directory. After unzipping the files, when I double click the "eclipse" executable file; the eclipse works perfectly fine. But If I unzip the ADT in a different directory, in my case directory E: (is shown when I boot in windows 7) There double clicking the same "eclipse" executable file does not run eclipse. It shows error message: Could not display /media/Software/00.AndroidLinux/ADT/eclipse/eclipse. There is no application installed for executable files. Do you want to search for an application to open this file? If I press yes in the Dialog, it finds "Pypar2" which is not my solution. I found that the "eclipse" file permission is following -rw------- 1 tanvir tanvir 63050 Feb 4 19:05 eclipse I tried to change the permission by "chmod +x eclipse" , but no use. This command does not change the file permission at all in this case. what should I do? Relevant output of cat /proc/mounts: /dev/sda6 /media/Software fuseblk rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096 0 0 Please not that I'm new to Ubuntu and still learning day by day.

• Remote sessions limited to two of many monitors?

  - by Xaephen

  I have 3 monitors attached to my local PC arranged in a triangle. My goal is to have the top monitor display local content, while displaying a remote session across the bottom two. I have gotten this to work with span and RDP, but I am looking for a software that would allow the remote sessions to be restricted to a number of monitors of my choosing, rather than spanning. Does this software exist? I've looked extensively. If there is a hack or something that might do it, I'm totally down for getting my hands dirty.

• How can I improve the rendering performance of this old DOS application?

  - by MicTech

  I have very old DOS Application (CadSoft Eagle - PCB Designer) and I want to work with it on my workstation with Windows 7. Then I install Windows 98 and that software into VmWare Player. But that software has serious problem with redrawing screen. It's very slow in comparison with my Intel Celeron 333MHz with Windows 98. I have same problem if I try to use DOSBox on Windows XP (same Celeron 333MHz). I also trying run this application directly on Windows XP (same Celeron 333MHz) with compatibility mod set to "Windows 98", but I get "(0Dh): General Protection Fault". Can someone give me good advice how I solve that?

• ADF Hands on Training &ndash; Prerequisites for 22nd March 2011

  - by Grant Ronald

  For those of you coming to the ADF Hands on training on the 22nd March in London, there was a link to the prerequisites.  Unfortunately, in a reshuffle of content on OTN, this page was removed.  So, over the next day or so I’m hoping to the pull together the relevant information into this blog post.  So keep checking back! Firstly, you need to being your laptop with you to do the hands on exercises.  No laptop, no hands on. Recommended 2GB RAM running Microsoft Windows XP SP2, 2003 Server SP2, Vista (32 bit only), Windows 7 or Linux or Mac 2GHz Processor (less will be acceptable but slower) Mozilla Firefox 2.0 or higher, Internet Explorer 7 or higher, Safari 3.0 and higher, Google Chrome 1.0 or higher Winzip or other extracting software Adobe Acrobat reader Flash (if you want to see dynamic graphs in your application) As for software, you will need have installed JDeveloper 11g.  The hands on instructions are based on 11.1.1.2 (or is it 11.1.1.3)! anyway, either of those or 11.1.1.4 would be required. You also need an Oracle database on your machine and access to the HR schema (which should be unlocked).  Don’t expect to have access to a network and VPN to a database. A simple test, unplug your laptop from your corporate network, run up JDev  and select File –> New –> Database connection and make sure you can connect to HR database and see the Emp/Dept etc tables.  If you can do that, you should be good to go. I would strongly recommend ensuring you have this in place before you arrive on Tuesday. Look forward to seeing you there.

• Should I install an AV product on my domain controllers?

  - by mhud

  Should I run a server-specific antivirus, regular antivirus, or no antivirus at all on my servers, particularly my Domain Controllers? Here's some background about why I'm asking this question: I've never questioned that antivirus software should be running on all windows machines, period. Lately I've had some obscure Active Directory related issues that I have tracked down to antivirus software running on our domain controllers. The specific issue was that Symantec Endpoint Protection was running on all domain controllers. Occasionally, our Exchange server triggered a false-positive in Symantec's "Network Threat Protection" on each DC in sequence. After exhausting access to all DCs, Exchange began refusing requests, presumably because it could not communicate with any Global Catalog servers or perform any authentication. Outages would last about ten minutes at a time, and would occur once every few days. It took a long time to isolate the problem because it was not easily reproducible and generally investigation was done after the issue resolved itself.

• What are those CPU control panel softwares called?

  - by Tim

  My computer is running an AMD Phenom II quad core CPU but it didn't come with the piece of software that I see people have in a lot of youtube videos. The software is kind of like the ATI catalyst control center but for the AMD processor instead. It shows things like current core temperature, clock speed, etc and I am not sure but maybe it also allows the user to make changes to those things from the control center as well. I am having a hard time finding the download for this online, especially since I don't even have the name for it.

• Running Windows XP with VMWare Fusion from a Fujitsu-Siemens recovery disk.

  - by Time Machine

  I have installed a trail version from VMWare Fusion. I had (sold now) a very old Fujitu-Siemens laptop (from around 2001) which came with two recovery disks (which I still have :P). One recovery disk is a Windows XP installer, the other is a disk with drivers and useless software you will never use and run permanently in the background. If I install Windows XP from the recovery disk (which did not contain any software except what comes with Windows XP, for as far as I know), will it run in VMWare Fusion? Or do I really have to buy/pirate a new Windows XP installation disk? Thanks. Yes, I need XP, not 7.

• BlueScreens on my ThinkPad with Windows 7 64 Bit and a SSD (CRITICAL_OBJECT_TERMINATION, ntoskernel.exe)

  - by pvorb

  I'm getting BlueScreens about every five days for more than three months. Here's an example: A problem has been detected and Windows has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: ntoskrnl.exe CRITICAL_OBJECT_TERMINATION If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps: Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need. If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode. Technical Information: *** STOP: 0x000000f4 (0x0000000000000003, 0xfffffa80065f2b30, 0xfffffa80065f2e10, 0xfffff80002f9bf40) *** ntoskrnl.exe - Address 0xfffff80002c98d00 base at 0xfffff80002c19000 DateStamp 0x4d9fdd5b It's has always been the same BlueScreen message showing CRITICAL_OBJECT_TERMINATION, 0x000000f4, and ntoskrnl.exe. Of course the addresses change. My computer is a ThinkPad T400 (about 2 years old) with a SSD in it. I'm also running Windows 7 Professional 64 bit. When I bought my computer, it had a 250GByte SeaGate HDD in it, which I replaced by a 500GByte HDD by Western Digital. Last september I bought a Corsair F120 SSD and replaced the HDD by this SSD. Then I bought a LEICKE HDD adapter for the UltraBay II where I plugged in my 500GByte HDD. This configuration ran about half a year without any errors. After re-installing Windows this spring, I am getting regular BlueScreens. Sometimes my system runs for about 2 weeks without a BSOD, sometimes I get several BlueScreens a day. The only thing that I noticed is, that I'm always running Google Chrome when it happens. Is there anyone who has made his/her own bad experiences whith some of my components or is there anybody who can tell me if it would be helpful to send my notebook to Lenovo? Thank you very much for your help on my issue! Regards, Paul

• How to clean a computer with multiple accounts infected with spyware, viruses? [closed]

  - by DjKilla

  Possible Duplicate: What to do if my computer is infected by a virus or a malware? What's the best way to clean a computer with multiple accounts infected with spyware, viruses and malware? Should you install and run software to remove the infections on each account? If you install the software on one account, will it clean the entire computer including each account? For example, some programs like CCleaner will install only on one account and not offer the option for all users (accounts). Does this mean the program will clean the entire computer including other accounts or do I have to install CCleaner on each account to clean up each user's account?

  Hi All, I have a friend that hosts his website on IIS and Windows Server 2003 R2 32-bit. He has .WMV files and .MPG and others and some of these are 30 mb in size! He wonders why users complain the site is slow! So my question is how can we reduce the size of these movies? What software? What settings for bit-rate, etc? Is there free software? I can use either a Mac or a PC. Thoughts are appreciated.

• Backup folder on sometimes attached external usb harddrive

  - by ctrler

  My girlfriend no longer has space her laptops drive to store her photos. The drive she has now is 750GB, so to go to a bigger drive would be expensive, as there isn't many 1.5tb 2.5 inch 9.5mm hdd on the market (as of now, there is only one). Because of that, I am thinking of moving her pictures to a cheap external usb hdd. As of now, I'm automatically backing up her important folders (My Documents, Pictures, etc.) using Windows 7 default backup software to a network drive. My problem is that I don't know of a good solution to automatically backup a folder residing on an usb disk. The usb disk won't be attached to the computer all the time, so I can't just treat it as a normal backup folder. Sometimes the backup would run and the folder would not be there! Anyone knows any software or methodology to backup folders on external usb hard drives that are not always present? Thanks

• Need guidelines for studying Game Development

  - by ShutterBug

  Hello Everyone, I've completed my graduation in Computer Science and currently working as a Software Engineer in a software company. I was wondering if I can build my career in Game Development. If so, what should be my approach. I've a few questions: Which universities to apply for masters? Preferably in Canada. Scholarships available? How shall I prepare myself before applying which shall give me an edge or advantage over others? I know Java, C#, PHP etc. I dont think these languages will be needed in Game Development. In that case, what languages shall I focus on from now? How do I get some ideas about IDE/Engines/Platform of game development? I'm not talking about flash/browser games. Please suggest me anything you want as I don't know much about it so I'm most likely to miss the most important questions. Feel free to make this thread a starter guide for those interested in perusing their career in game development. Post every relevant information. Thanks in Advance. EDIT: I can see a lot of people suggested to build a small project/game. If so, please suggest me how do I start a small game developing (maybe a clone to some existing small games ie pacman, brick game etc) from start to end.

• Entry level engineer question regarding memory management

  - by Ealianis

  It has been a few months since I started my position as an entry level software developer. Now that I am past some learning curves (e.g. the language, jargon, syntax of VB and C#) I'm starting to focus on more esoteric topics, as to write better software. A simple question I presented to a fellow coworker was responded with "I'm focusing on the wrong things." While I respect this coworker I do disagree that this is a "wrong thing" to focus upon. Here was the code (in VB) and followed by the question. Note: The Function GenerateAlert() returns an integer. Dim alertID as Integer = GenerateAlert() _errorDictionary.Add(argErrorID, NewErrorInfo(Now(), alertID)) vs... _errorDictionary.Add(argErrorID, New ErrorInfo(Now(), GenerateAlert())) I originally wrote the latter and rewrote it with the "Dim alertID" so that someone else might find it easier to read. But here was my concern and question: Should one write this with the Dim AlertID, it would in fact take up more memory; finite but more, and should this method be called many times could it lead to an issue? How will .NET handle this object AlertID. Outside of .NET should one manually dispose of the object after use (near the end of the sub). I want to ensure I become a knowledgeable programmer that does not just rely upon garbage collection. Am I over thinking this? Am I focusing on the wrong things?

• Discrete Math and Computing Course

  - by ShrimpCrackers

  I was recently admitted into a Computing and Software Systems program (basically software engineering) and one of the first courses I'll be taking is called Mathematical Principles of Computing. The course description: "Integrating mathematical principles with detailed instruction in computer programming. Explores mathematical reasoning and discrete structures through object-oriented programming. Includes algorithm analysis, basic abstract data types, and data structures." I'm not a fan of math, but I've been doing well in all my math classes mostly A's and B's ever since I started two years ago, and I've been doing math every quarter - never took a quarter without math - so I've been doing it all in sequence without gaps. However, I'm worried about this class. I've read briefly on what discrete math is and from what my advisor told me, its connection with computer science is that it has alot to do with proving algorithms. One thing that my instructors briefly touched on and never went into detail was proving algorithms, and when I tried, I just wasn't very good at mathematical induction. It's one of the things that I ignored every time it showed up in a homework problem (usually in Calculus III which I'm finishing up right now). Questions: 1. What can I expect from this class? 2. How can I prepare myself for this class? 3. Other tips? Thank you.

• Explorer fails to load with UAC enabled

  - by user37679

  While running an InstallShield based installer, my Windows 7 machine became unresponsive. After forcing a reboot, I can log in to the system, but explorer does not run. I can log in as a different user without issue and when I change UAC to its lowest setting, I can log in as the user that was performing the install. However, if I re-enable UAC, I am unable to get explorer to run again on login. I have checked the HKCU\Software\Microsoft\Windows\CurrentVersion\Run and RunOnce, but don't see anything that isn't configured to run on startup. I completed the installation of the software as the "good" user without issue.

• Alternatives to time tracking methodologies [closed]

  - by Brandon Wamboldt

  Question first: What are some feasible alternatives to time tracking for employees in a web/software development company, and why are they better options Explanation: I work at a company where we work like this. Everybody is paid salary. We have 3 types of work, Contract, Adhoc and Internal (Non billable). Adhoc is just small changes that take a few hours and we just bill the client at the end of the month. Contracts are signed and we have this big long process, the usual. We figure out how much to charge by getting an estimation of the time involved (From the design and the developers), multiplying it by our hourly rate and that's it. So say we estimate 50 hours for a website. We have time tracking software and have to record the time in 15 we spend on it (7:00 to 7:15 for example), the project name, and give it some comments. Now if we go over the 50 hours, we are both losing money and are inefficient. Now that I've explained how the system works, my question is how else can it be done if a better method exists (Which I'm sure one must). Nobody here likes the current system, we just can't find an alternative. I'd be more than willing to work after hours longer hours on a project to get it done in time, but I'm much inclined to do so with the current system. I'd love to be able to sum up (Or link) to this post for my manager to show them why we should use abc system instead of this system.
