Although both APIs are conceptually similar, the log4j API is significantly more flexible and offers many more features, too numerous to be listed here. You will discover that the additional features and flexibility turn out to be indispensable in the context of a mission-critical application. The open and collaborative way in which log4j is developped ensures that it continues to preserve and even widen its competitive edge.

To answer my own question... I uninstalled 1.5 and installed 1.4. Compiled and works fine. I suspect this is actually a problem with Ant. Is it possible to extend for example the form object in Flow? So that we have our own implementation of it? If so, are there examples. ps why was Flow written in javascript, and not java? Probably a stupid one:). Do you serialize it to JPG or PNG? Otherwise this error can not occur. But if, it's of course no longer SVG.

Retroweaver is a Java bytecode weaver that enables you to take advantage of the new 1.5 language features in your source code, while still retaining compability with 1.4 virtual machines. Retroweaver rewrites class files so that they are compatible with older virtual machines. Check out http://sourceforge.net/projects/retroweaver .

By fail-stop, we mean that log4j will not throw unexpected exceptions at run-time potentially causing your application to crash. If for any reason, log4j throws an uncaught exception, please send an email to the log4j-user@logging.apache.org mailing list. Uncaught exceptions are handled as serious bugs requiring immediate attention. Moreover, log4j will not revert to System.out or System.err when its designated output stream is not opened, is not writable or becomes full.

This is an x4juli FAQ. Please have a look at the project pages for their documentation regarding usage in user code.

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.

In JDK 1.4, there is an Endorsed Standards Override Mechanism which can be used to override the classes in the JDK itself. One way to replace the classes in the JDK with the classes contained in a set of jar files is to place the jar files in some directory, "my-endorsed", and define a system property. For example, to use a newer version of Xalan, place the newer version of xalan.jar in the "my-endorsed" directory and invoke the Java launcher with the -Djava.endorsed.dirs= my-endorsed option.

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.

Yes. Any product conforming to the J2EE 1.3 or later specifications can be used to run this benchmark. CTS certification ensures that the application server being tested is a J2EE technology-based application server and not a benchmark-special application server that is crafted specifically for SPECjAppServer2004. The CTS certification is validated by Sun Microsystems, Inc.

The J2EE 1.4 specification is final and you can use the J2EE 1.4 SDK to deploy applications today. However, for improved reliability,scability, and performance, it is recommended that you deploy your applications on J2EE 1.4 commercial implementations that will be available early in 2004. If you want to deploy your application before 2004, and reliability,scability, and performance are critical, you should consider using a high performance application server that supports J2EE v1.

The Fotolia API is a tool that allows a website to make requests to the Fotolia database and receive results with images. Thus, your website visitors can search images on your website without leaving it, and they will become your affiliates if they register on Fotolia. In addition the Fotolia API can be used to integrate our services in your product (search and purchase functions) or to build applications using Fotolia (plugin, add-on software, web service, widget etc).

The commons-logging project provides the commons-logging API (commons-logging-api-nn.jar) along with an implementation (commons-logging-adapters-nn.jar) that provides a wrapper between the API and the actual logging libraries used underneath (such as log4j, java.util.logging, etc). However, in order to determine what implementation should be used, commons-logging library tries to do some classloading-based discovery that is fragile and can fail unexpectedly.

Signal-chaining enables the Java Platform to better interoperate with native code that installs its own signal handlers. The facility works on both Solaris and Linux platforms. The signal-chaining facility was introduced to remedy a problem with signal handling in previous versions of the Java Hotspot VM. Prior to version 1.

Java Swing GUI applications (including JDebugTool) can hang in JDK 1.4. The work around is to add the following argument to java -Dsun.java2d.noddraw=true

The following document describes what you need to do to get JDK 1.4 (also known as Java 2 version 1.4) operational on your iSeries running OS/400 V5R1 : http://www-912.ibm.com/s_dir/slkbase.NSF/1ac66549a21402188625680b0002037e/0581029cdbcafcbd86256c4f00673b7d?OpenDocument

A sample server that illustrates Non-Blocking Socket I/O can be found at http://www.owlmountain.com/tutorials/NonBlockingIo.htm.

Most likely, a non-daemon thread is running. JVM's do not shutdown until there are 0 non-daemon threads. You will need to perform a thread dump [kill -3 pid for Unix or CTRL+Break for Windows] to determine the code which started the thread.

We recommend to switch the default buffer type to 'heap' by inserting the following code before you start a server: If you prefer direct buffers to heap buffers, JVM might have ran out of direct memory. Please try increasing maximum direct memory size using -XX:MaxDirectMemorySize option (e.g. -XX:MaxDirectMemorySize=128M) Please make sure if you called ByteBuffer.flip() to flip the buffer before writing the buffer out. It is a common mistake NIO beginners make.

We recommend Sun's SDK for Java 1.4 or 1.3. Xindice will not work with the SDK 1.2 or earlier. When using 1.3, be aware that there are known issues with Sun's SDK for Java 1.3.1 on several Linux distributions, but 1.3.0 or 1.4.2 should work without any problems.

Ships" are short for "relationships." This is commonly a fanfic term, but if you support a particular pairing of characters between Harry Potter characters Several of you have accused me of "selling out" and all this other junk. I can tell you that it's downright hurtful, but I understand your own pain. I don't like that I have to put ads up, but there is a reason I must. I cannot afford to run the site on my own accord - and my parent's.

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.

The JavaMail API requires JDK/JRE 1.4 or higher. The JavaMail API is a Java optional package, it is not part of the core Java SE but is included in Java EE.

The JMS API can be used, in general, as a notification service; however, it does not define a distributed version of Java Events. One alternative for implementing distributed Java Events would be as JavaBeans components that transparently, to the event producer and listener beans, distribute the events via the JMS API. Even though there are many similarities, providing separate domains still seems to be important.
