Screenscraping from Java using jsoup – effective data gathering from websites

Lucas Jellema 4

In a recent article I discussed screenscraping in a in hindsight fairly clumsy way (https://technology.amis.nl/blog/12786/building-java-object-graph-with-tour-de-france-results-using-screen-scraping-java-util-parser-and-assorted-facilities). While preparing for a series of articles on data visualizations, I had need of statistics regarding the Olympic Games – more specifically: the overall medal count per country during the 2008 Bejing Olympic Games. This […]

Using JPA to persist the Tour de France Java Object Graph to relational database tables

Lucas Jellema 1

In a recent article – https://technology.amis.nl/blog/12786/building-java-object-graph-with-tour-de-france-results-using-screen-scraping-java-util-parser-and-assorted-facilities – I described how I retrieved the statistics for recent Tour de France editions from the official Tour de France website from my Java program and constructed an Java Object Graph for the data on stages, riders and rankings. In this article, I will […]

Turning any XML document into a Java Object graph using JAXB 2.0

Lucas Jellema 1

As a followup to my recent article on how to Produce and XML document based on data in a POJO structure using JAXB (https://technology.amis.nl/blog/12499/creating-an-xml-document-based-on-my-pojo-domain-model-how-will-jaxb-help-me) I will describe in this article how to go the reverse route: how to take any XML document and process it into a Java Object graph. […]

Leveraging HTML 5 Navigator API to show the browser's current location on an ADF Faces 11gR2 Thematic Map component

Lucas Jellema

This article demonstrates how, through a bit of JavaScript interacting with the HTML 5 Navigator API, some more JavaScript using the ADF Faces Rich Components API and the ADF Faces 11gR2 Thematic Map component, it becomes quite easy to not only learn about the end user’s physical location but to […]

Leveraging Spring Beans in ADF Faces applications and using the Spring PropertyPlaceholderConfigurer bean to dynamically configure bean properties from external files

Lucas Jellema 1

The Spring Framework is omnipresent in the world of Java applications. Many developers, teams and organizations make use of Spring for various reasons, such as its persistency support, the AOP features, the MVC framework or the remoting options or the security facilities. Underlying all of these is the bean container, […]

No JDBC based data retrieval in Java applications – RESTstyle, JSON formatted HTTP based interaction from Java to Database

Lucas Jellema 1

This article demonstrates how Java application can query data from relational databases (well, in this case more specifically the Oracle RDBMS) without the use of plain old JDBC but instead through a simple HTTP interaction with a RESTful service that returns the data in JSON format. In this way, issues […]

Oracle Diagnostics Logging (ODL) for application development

Aino Andriessen 1

Logging is a very important aspect of application development as it offers run-time access to the behaviour and data of the application. It’s important for debugging purposes but also to investigate exception situations on production. The Java developer has a choice between logging frameworks but Log4J is probably the most […]

JavaOne 2010 presentation: Why and how to engage a Complex Event Processor from a Java Web Application

Lucas Jellema

Complex Event Processors are capable of handling large volumes of events – by filtering, aggregating or detecting patterns. Java Applications use a CEP to pre-process incoming signals. These applications can also generate the events – for example the user click and navigation behavior in the web application – and report […]
