Log4j is the way Openbravo saves logs (errors or information about the application data). Logs are very useful in order to know where and why the application crashed. Log4j configuration is managed with /tomcat/webapps/openbravo/WEB-INF/log4j.lcf file, here is defined where the log will be stored, this is done in a line that looks like: The previous line means that the log is stored in /tomcat/logs/log4j_TAD.log file.

Messages shown in log files have different categories (debug, info, warn, error and fatal). By default the messages shown are from error to fatal but this can be customized. When you select a category all messages which belong to this category or to a higher one will be displayed. To do this there are two ways: From application Go to General Rules > Data > Utility > Session info > Change logs, this will show every java class used till now.

You configure each section (numbered 1-10) by pointing DSpy to the proper directory on your network. By putting a shortcut to DSpy in your startup folder, it will start with your TSC client during every boot/login and automatically start tracking your TSC progress.

The short answer: the log4j classes and the properties file are not within the scope of the same classloader. The long answer (and what to do about it): J2EE or Servlet containers utilize Java's class loading system. Sun changed the way classloading works with the release of Java 2. In Java 2, classloaders are arranged in a hierarchial parent-child relationship. When a child classloader needs to find a class or a resource, it first delegates the request to the parent.

Yes. Both the DOMConfigurator and the PropertyConfigurator support automatic reloading through the configureAndWatch method. See the API documentation for more details. Because the configureAndWatch launches a separate wathdog thread, and because there is no way to stop this thread in log4j 1.2, the configureAndWatch method is unsafe for use in J2EE envrironments where applications are recycled.

My machine has a system drive and a disk array. Should I setup the file cache to the system drive or the disk array? You should set the File Cache to use the disk array as it Should the file cache be the same as the file location? The File Cache can be any drive attached to the system, or even a network drive. Ideally use the fastest drive available. I set the File Cache to the disk array, but I do not see any temp files created within the folder.

Get Guido Carls' <gcarls@cpan.org> Log::Log4perl extension Log::Log4perl::Layout::XMLLayout from CPAN and install it: perl -MCPAN -eshell cpan> install Log::Log4perl::Layout::XMLLayout Install and start Chainsaw, which is part of the log4j distribution now (see http://jakarta.apache.org/log4j ). Create a configuration file like <log4j:configuration debug="true"> <plugin name="XMLSocketReceiver" class="org.apache.log4j.net.

Log4j versions upto and including 1.2.8 are compatible with JDK 1.1.x and later. Log4j version 1.3 will be compatilble with JDK 1.2 and later. The DOMConfigurator is based on the DOM Level 1 API. The DOMConfigurator.configure(Element) method will work with any XML parser that will pass it a DOM tree. The DOMConfigurator.configure(String filename) method and its variants require a JAXP compatible XML parser, for example Xerces or Sun's parser.

log4j is fail-stop. However, altough it certainly strives to ensure delivery, log4j does not guarantee that each log statement will be delivered to its destination. Logging behavior can be set at runtime using a configuration file. Configuration files can be property files or in XML format. log4j can direct its output to a file, the console, an java.io.OutputStream, java.io.

Tfollowing are the critical configuration lines in your pinerc file. The folder collection syntax is specific to the version of IMAP that is running on SC - and would be unlikely to be guessed by a casual user. This info came from http://www.ii.com/internet/messaging/imap/isps/ Getting Eudora to read SpamCop mail using IMAP is straightforward. Adding Secure Sockets Layer (SSL) encryption requires additional steps. The first step is to create a "personality" for SpamCop email.

To configure the Outlook plugin, you should choose SpamBayes Manager from the SpamBayes button on the SpamBayes toolbar. If you use the POP3 proxy or IMAP filter, then simply open a browser window to http://localhost:8880, click on the configuration link on the top right of the page that opens up, and fill in the details. With the POP3 proxy, when you need to select local port numbers to proxy on, if you are only proxying one server, then try 110 first.

DenyHosts uses a simple configuration file. An example, denyhosts.cfg-dist is supplied in the distribution. This file should be copied to denyhosts.cfg and edited to match your system configuration.

x4juli is a port of the backend part of log4j. It is a full port, so it does not use wrapper classes around the backend, instead it internally extends java.util.logging classes.

I am having the same problem, it keeps saying it can't find the resource specified. Example: a call from a html like href="HelloWorld" I have tried everything, what am I doing wrong? This is just a simple helloworld servlet. I have j2ee, java1.4 installed and variables set.

Connected Communities does not carry out this service. Our installation contractor may choose to offer this service, otherwise local computer retailers may be able to help as may other members of the community.

Because log4j is configured by default to log to a file, you may want to remove it from the implementaton. Doing this is quite simple - modify gov.nist.core.LogWriter.java. You can change its behavior to log to a network connection or remove it entirely and convert to println. The Listener may have blocked while processing a transaction. Do not block in your listener method. If you need to block, start a thread and block in it dont block in the thread that you were called in the listener.

In case of problems with an application, it is helpful to enable logging so that the problem can be located. With log4j it is possible to enable logging at runtime without modifying the application binary. The log4j package is designed so that log statements can remain in shipped code without incurring a high performance cost. It follows that the speed of logging (or rather not logging) is capital. the same time, log output can be so voluminous that it quickly becomes overwhelming.

Make sure to read the short manual. It is also recommended to you read The complete log4j manual which is much more detailed and up to date. Both documents were written by Ceki Glc. Yes, log4j is thread-safe. Log4j components are designed to be used in heavily multithreaded systems. The log output can be customized in many ways. Moreover, one can completely override the output format by implementing one's own Layout.

Contrary to the GNU Public License (GPL) the Apache Software License does not make any claims over your extensions. By extensions, we mean totally new code that invokes existing log4j classes. You are free to do whatever you wish with your proprietary log4j extensions. In particular, you may choose to never release your extensions to the wider public. We are very careful not to change the log4j client API so that newer log4j releases are backward compatible with previous versions.
