The Habari ActiveMQ Client library for Delphi and Free Pascal can be used for monitoring of Java(tm) applications which use the popular Apache Log4j logging framework.
This screenshot shows the output of a Delphi console application. It listens to a logging topic which receives log messages from an ActiveMQ message broker. The log messages have been sent to the logging topic using the Log4J JMSAppender.

Delphi application receiving Apache Log4j messages
How does it work?
It is possible to use serialization in the opposite direction: a log event object can be created in Delphi code and then sent to the message broker. ActiveMQ will then convert them to native Java log events. A Java application then can create a consumer for the log topic and receive the log events from Delphi.
Update: the HabariActiveMQObjectExchange download now includes the Java and Delphi source code for the Log4j logging message publisher and subscriber examples.

betasoft today announced the public alpha test of madxnet, a web application for processing of bug reports created by madExcept.
Delphi and C++Builder developers are invited to try the alpha version with their own bug reports. Bug reports can be sent to madxnet using the http protocol.
The madxnet web application offers these advantages:
(Go to: Events | Reports | Exceptions | Executables)
Easy to maintain: Google has a reputation for highly reliable, high performance infrastructure. With App Engine you can take advantage of the 10 years of knowledge Google has in running massively scalable, performance driven systems. App Engine will always be free to get started, and you can purchase more computing resources, paying only for what you actually use. An efficient application on a free account can use up to 500MB of storage and up to 5 million page views a month.
The madxnet example installation does not require a Google account. It is free to use and accepts http uploads without restrictions. Only for attached screenshots there is a 200 KB size limit. (This limitation will be changed when automatic scaling of incoming image data is implemented.)
Note to testers: please be aware that all uploaded bug reports are visible for everybody. In case you need to undo a bug report upload: it is possible to delete all bug reports using a simple http request. Please read the Frequently Asked Questions page for more information.
Update: version 0.6 now introduces charts. See the Exceptions page for an example.

The new version of GlassFish is the industry’s first application server to support the new Java™ Platform Enterprise Edition 6 (Java EE 6).
GlassFish v3 includes version 4.4 of Open Message Queue, a Java Message Service (JMS) message broker, as the default JMS provider. For Delphi developers, the interesting new feature in this release of OpenMQ is that it can exchange JMS messages with non-Java clients using the Stomp message protocol.
For Delphi developers, this means that asynchronous message exchange between web applications and EJB (Enterprise JavaBeans) and integration of applications running on GlassFish v3 becomes possible.
This tutorial shows the steps to build and run web application on the Java platform with the NetBeans 6.8 IDE and GlassFish v3 which sends message to the OpenMQ Java Message Service (JMS) message broker included in GlassFish. A Delphi message consumer application created with the Habari OpenMQ Client library then can be used to receive the messages from the broker asynchronously.
Update: the second part of the tutorial will guide you through the creation of a simple EJB application for GlassFish v3 which uses a Message Driven Bean to receive messages from a message queue on the embedded OpenMQ broker. The Delphi ProducerTool application sends messages to the message queue.
About GlassFish v3
GlassFish v3 is the industry’s first application server to support the new Java Platform Enterprise Edition 6 (Java EE 6).
About Open Message Queue (OpenMQ)
Open Message Queue is an enterprise quality, production ready, scalable messaging server. It provides a complete Java Message Service (JMS) implementation for message oriented system integration. Read more: https://mq.dev.java.net/about.html

Sun GlassFish Enterprise Server v3 is the industry’s first application server to support the new Java Platform Enterprise Edition 6 (Java EE 6). Java EE 6 introduces features to increase the flexibility of the platform and enable companies to use the new, lightweight Web Profile, in addition to the full enterprise platform, to help meet their business requirements.
GlassFish is the industry’s most downloaded Java EE compatible application server, with over 24 million downloads to date.
NetBeans IDE 6.8 is the first IDE to offer complete support for the entire Java EE 6 spec with improved support for JSF 2.0/Facelets, Java Persistence 2.0, EJB 3.1 including using EJBs in web applications, RESTful web services, and GlassFish v3.
December 10, 2009 Sun Microsystems, Inc. (NASDAQ: JAVA) today announced the availability of the Java Platform Enterprise Edition 6 (Java EE 6) and significant industry support from Java technology licensees including Caucho, IBM, Oracle and Red Hat. Java EE is the premier platform for web and enterprise application development and deployment. Java EE 6 introduces features to increase the flexibility of the platform and enable companies to use specific application scenarios, in addition to the full enterprise platform, to help meet their use case requirements. The Java EE SDK has been downloaded more than 18 million times and the specification is supported by 28 licensees that market Java EE compatible-products. Developers can download and begin deploying Java EE applications today using the Java EE SDK available at: http://java.sun.com/javaee/downloads/index.jsp

betasoft released a web application at http://hbm2pascal.appspot.com/ which can generate Object Pascal source for database objects based on Hibernate mapping documents.
How to use hbm2pascal: the web page contains a form which shows an example Hibernate mapping document, and a button to start the code generation. The example document may be edited freely. hbm2pascal will parse the table descriptions (including table relationships) and build Object Pascal source code. The generated sources then will be displayed and can be copied from the results page, or sent by email.
Hibernate mapping documents can be created manually, or extracted from metadata for existing databases using Hibernate Tools, a free toolkit available at http://www.hibernate.org/
The code templates used by hbm2pascal can be customized to generate source code specifc for O/R mappers like tiOPF, hcOPF, InstantObjects and the G Framework. Applications which use these object persistency frameworks and hbm2pascal will not require Hibernate at run time. Hibernate Tools are only required in the first step, to reverse engineer the metadata of an existing database to hbm mapping files, which then will be converted by hbm2pascal.
