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

x4juli delivers all necessary classes as specified on http://slf4j.org/faq.html section "Implementing the SLF4J API". You simply have to remove all sl4fj-xxxxx.jar from the classpath.

Second part: You have to make Jakarta Commons Logging use the x4juli JCLFactory. There are two possibilities: Specify a system property on your jvm startup (script): -Dorg.apache.commons.logging.LogFactory=org.x4juli.JCLFactory or put in an commons-logging.properties file in your classpath with org.apache.commons.logging.LogFactory=org.x4juli.JCLFactory property line in the file.

Long answer: Java Commons Logging introduces a classloader hell that is discussed to some extend by the author of Log4J here and here. Thus, Coverlipse adds the Java Commons Logging package to those handled by the system classloader. This way, projects that use Java Commons Logging can be tested with Coverlipse. However, it is not possible to test the Java Commons Logging itself with coverage by Coverlipse. Again, this is a problem occurring only with Eclipse 3.0.

x4juli provides a native implementation for org.apache.commons.logging.Log interface and for the org.slf4j.Logger interface. x4juli uses the standard way of each facade to implement the corresponding factory. In case of Jakarta Commons Logging you still have to use the originally provided jar and put an config entry in the right place (System property or config.file). In case of slf4j you have to do nothing but remove all other sl4fj-xxxxx.jar files from the classpath.

SLF4J is conceptually similar to JCL. As such, it can be thought of as yet another logging facade. However, SLF4J is orders of magnitude simpler in design and arguably more robust.

Yes in signed applets, but no in unsigned applets (most cases). Since we do not allow unsigned applets access to any communications port under the JDK1.1 security model, you can not use the Java communications API with unsigned applets. We do plan to be compliant to JDK1.2 security model in later releases, which might allow trusted applet access to ports. The javax.comm.properties file is not intended to be edited by users.

The Enterprise JavaBeans (EJB) 3.0 specification includes an additional persistence specification called the Java Persistence API (JPA). It is an API for creating, removing and querying across lightweight Java objects and can be used both within a compliant EJB 3.0 Container and a standard Java SE 5 environment.

Out of the box -- probably not unless MS started shipping the RMI classes. There's a little bit of RMI used in the admin of Tomcat. Other than that, it should run just fine. IBM has apparently packaged up the RMI classes missing from the Microsoft JVM and is distributing them at http://www.alphaworks.ibm.com/formula/RMI.

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 rules that Digester applies to input XML can be configured from java code, by instantiating various rule object types, and adding them to the digester. Alternatively, Digester can be asked to read the rules from an external configuration file (itself in xml format) that is called an xmlrules file.

There are many flight options for how to get to Jakarta. Please check with your local agent or on the internet to find a cheap and convenient route. We will meet you at the airport in Jakarta and bring you to the venue. But you will have to inform us of the exact date and time you will arrive and depart from the airport (including the flight number).

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.

Simple Solution is safe on all surfaces that you can use water on. Some good examples are carpets, rugs, upholstery, mattresses, tile, grout, concrete, painted walls that can be washed and wood that is sealed. It's perfect for treating stained laundry.

The file LeoDocs.leo contains two "Hello World" programs, one using @file trees and the other using @root trees. The file LeoPy.leo contains a large number of other examples, some small, some large and complex.

JARGON is a pure Java API for developing SRB (or other) datagrid interfaces. The API currently handles file I/O for local and SRB file systems and is easily extensible to other file systems. File handling with JARGON closely matches file handling in Sun's java.io API, a familiar API to most java programmers.

Perhaps you've come across a scenario where you'll want a JSON string like "{'id':1}" transformed back to a Java class, but the catch is that the id property is not a simple value but another class (a complex value), say a wrapper around a primitive long. If you try to serialize such a string back to Java you'll get a ClassCastException.

We have a developed a prototype provider (referred as the WS provider) for invoking simple Web services using the Java CoG Kit task model. The current implementation allows invocation of remote methods with only String parameters. Source code demonstrating its usage is available in the CVS in the file ServiceInvocation.java Furthermore, you can use the cog-ws-invoke command as follows: bash-2.05b$ .
