  • How to create a CMS web site using OFBiz

    I need a simple how-to tutorial on developing a simple CMS web site using the OFBiz CMS framework. There are absolutely no documentation of how OFBiz CMS works. Whatever is there in the official website is only about the data model used in OFBiz CMS application. If somebody can illustrate just a "Hello World" like application in OFBiz CMS, it will great help for me. Or can guide me to similar documents in web.

  • windows 7: Event 55 The file system structure on the disk is corrupt and unusable

    - by Radio
    Here is a real bad one! Windows 7 RTM with SP1 installed [Version 6.1.7601]. Recently tried to delete some folder on my hard drive and Windows prompted "Error 0x80070570: The file or directory is corrupted and unreadable", and at the same time placed an Event 55 describing "The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on \Device\HarddiskVolume2." Ran chkdsk, first with /f option, then with /r option. Result in both cases was: no errors found, 0 bad sectors. No problems chkdsk found at all! Went through StackExchange, Google and spent over 6 hours on this. Still cannot figure out the problem. Re-installing/Re-Formatting is not an option! What did I try: Hotfix - Windows6.1-KB982927-x64.msu - gave me an error about incompatibility with my computer, however it totally matches my system. CRC of hotfix was ok. Windows Repair Console found startup errors and fixed those, but this didn't help an issue, even by running chkdsk c: /R from it. http://support.microsoft.com/kb/246026 does not promise anything good. sfc /scannow does not help too. Replaced hard drive by cloning an old one using True Image, repeated all steps above. At the same time, some minor glitches started to appear in my Windows, like side panel and notification area settings are getting reset. Goal is to delete the folder and get rid of Event 55. Sounds like NTFS bug. Please help. This is completely ridiculous.

  • How to compute the probability of a multi-class prediction using libsvm?

    - by Cuga
    I'm using libsvm and the documentation leads me to believe that there's a way to output the believed probability of an output classification's accuracy. Is this so? And if so, can anyone provide a clear example of how to do it in code? Currently, I'm using the Java libraries in the following manner SvmModel model = Svm.svm_train(problem, parameters); SvmNode x[] = getAnArrayOfSvmNodesForProblem(); double predictedValue = Svm.svm_predict(model, x);

  • Should a Stack have a maximum size?

    - by Sotirios Delimanolis
    I'm practicing my knowledge of ADTs by implementing some data structures, even if most already exist. With Stacks, a lot of books and other documentation I've read talk about the stack throwing an error when you try to add an element but the stack is full. In a java implementation (or any other), should I specifically keep track of a maximum stack size (from constructor), check to see if that size is reached, and throw an overflow exception if it is? Or is not such a big deal?

  • Execute Assembly from Pascal

    - by London
    How can I execute this code from Pascal : MOV EAX, variable1 PUSH EBX, EAX MOV EAX, variable2 POP EBX AND EBX, EAX Where I define method/function arguments in function(variable1, variable2). This is a school assignment I don't know why they are making us do Pascal/Assembly instead of Java/C++ or such. This is not the whole assignment I did do plenty of work before I just need help with this, any help is appreciated thank you

  • running code if try statements were successful in python

    - by None
    I was wondering if in python there was a simple way to run code if a try statement was successful that wasn't in the try statement itself. Is that what the else or finally commands do (I didn't understand their documentation)? I know I could use code like this: successful = False try: #code that might fail successful = True except: #error handling if code failed if successful: #code to run if try was successful that isn't part of try but I was wondering if there was a shorter way .

  • Up to date, JPA compliant GenericDAO Implementation

    - by HDave
    I read this article: http://www.ibm.com/developerworks/java/library/j-genericdao.html several times and believe I understand what it is saying. However, it is 4 years old and I have a JPA compliant Java application to contend with. In addition, I see that there is a JPATemplate in Spring that has some good functionality, but the Spring documentation says it is already deprecated! Can anybody point me to a solid, modern, JPA compliant, Spring based, working example of a GenericDAOImpl that proxies an Interface to provide generic finder execution?

  • imageWithCGImage and memory

    - by Adam Ernst
    If I use [UIImage imageWithCGImage:], passing in a CGImageRef, do I then release the CGImageRef or does UIImage take care of this itself when it is deallocated? The documentation isn't entirely clear. It says "This method does not cache the image object." Originally I called CGImageRelease on the CGImageRef after passing it to imageWithCGImage:, but that caused a malloc_error_break warning in the Simulator claiming a double-free was occurring.

  • Karmic iptables missing kernel moduyles on OpenVZ container

    - by luison
    After an unsuccessful p2v migration of my Ubuntu server to an OpenVZ container which I am stack with I thought I would give a try to a reinstall based on a clean OpenVZ template for Ubuntu 9.10 (from the OpenVZ wiki) When I try to load my iptables rules on the VM machine I've been getting errors which I believe are related to kernel modules not being loaded on the VM from the /vz/XXX.conf template model. I've been testing with a few post I've found but I was stack with the error: WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. FATAL: Could not load /lib/modules/2.6.24-10-pve/modules.dep: No such file or directory iptables-restore v1.4.4: iptables-restore: unable to initialize table 'raw' Error occurred at line: 2 Try `iptables-restore -h' or 'iptables-restore --help' for more information. I read about the template not loading all iptables modules so I added modules to the XXX.conf of the VZ virtual machine like this: IPTABLES="ip_tables iptable_filter iptable_mangle ipt_limit ipt_multiport ipt_tos ipt_TOS ipt_REJECT ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_LOG ipt_length ip_conntrack ip_conntrack_ftp ip_conntrack_irc ipt_conntrack ipt_state ipt_helper iptable_nat ip_nat_ftp ip_nat_irc" As the error remained I read that I should build dependencies again on the virtual machine: depmod -a but this returned an error: WARNING: Couldn't open directory /lib/modules/2.6.24-10-pve: No such file or directory FATAL: Could not open /lib/modules/2.6.24-10-pve/modules.dep.temp for writing: No such file or directory So I read again about creating the directory empty and redoing "depmod -a" it. I now don't get the dependancies error but get this and I don't have a clue how to proceed: WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. FATAL: Module ip_tables not found. iptables-restore v1.4.4: iptables-restore: unable to initialize table 'raw' Error occurred at line: 2 Try `iptables-restore -h' or 'iptables-restore --help' for more information. I understand that iptables rules have to be different on the VM machine and perhaps some of the rules we are trying to apply (from our physical server) are not compatible but these are just source IP and destination port checks that I would like to be able to have available . I've heard that on the CentOS template there are no issues with this, so I understand is to do with VM config. Any help would be greatly appreciated.

  • Virtual channel tutorial for terminal services.

    - by Scott Chamberlain
    I am writing a program that will need to communicate to a server through a TS connection. Virtual Channels seems to be exactly what I need but Microsoft's documentation leaves very much to be desired. Does anyone know of good tutorials or just some examples I could use to help me. Preferred language is C# but C++ examples are fine too.
