Often unknown, or heralded as confusing, regular expressions have defined the standard for powerful text manipulation and search. Without them, many of the applications we know today would not function. This two-part series explores the basics of regular expressions in Java, and provides tutorial examples in the hopes of spreading love for our pattern-matching friends. (Read part two.)

I’m about to show you a pattern that will make your heart sing. I have to thank Brian Leathem for his original idea to use CDI events in the ValueChangeListener, but when combined with a little <f:ajax> magic, there’s almost no limit to what you can do without writing a single line of JavaScript. ValueChangeListeners are also the perfect opportunity to build an Event driven model into your application. Continue reading this article »
Lincoln Baxter, III speaks on the well and lesser known uses for URL-rewriting in modern web applications, how it can be used to increase security, enhance usability, and how it can supplement any new or existing application – no matter the language or technology.
It’s quite simple really. All you need to do is install Apache HTTPd, then set make sure you have a few modules installed and set up:
Instructions below are for Ubuntu, Fedora, RHEL, or other Linux distributions. The results of this configuration can be seen at scrumshark.com, our latest open-source project management software initiative. We’re looking for contributors! (that means you.) So please come get involved! We are looking for help with the front-end graphical design and widgets like charts, graphs, and visualizations (or anything you are interested in.)
We are sorry for any inconvenience that may have been caused by our brief downtime. We have moved to a new server, and are now fully operational once more. Due to the hack, we were forced to re-evaluate the security of our previous host, and decided that we could not be adequately certain that such attacks would not succeed in the future; we’ve subsequently moved to a new host, and are very happy with the provisions (and increased level of service.)
Please enjoy the new, faster, more stable OCPsoft.com.
We regret to inform you that the hosting provider we use for OCPsoft.com, and our website itself has recently come under attack. The hack utilized our caching provider to place inappropriate advertising and unrelated content on our website for the promotion of a product. We have removed the source of the problem, but cached files are still being served from DNS caches and proxies.
Thank you for your patience as we work to clean up the remaining impacts of this problem, and we apologize for any delay or inconvenience that this has caused.
When my family comes together for special occasions, it is official tradition to begin, fill, and end any given evening with a debate on social justice, politics, science, religion, or a combination of the above. This year was no different, with our post-feast discussion ranging from human rights to geological timelines of carbon fuel consumption rates. The topic that interested me the most, however, was HR 3261 – new “Anti-piracy” legislation from the MPAA and RIAA, currently making its rounds through congress.
The MPAA and RIAA are trying blacklist websites, block IP addresses, and change fundamental assumptions about the market we operate in – all under a new law that will tie the hands of the internet…
For those of you who are unfamiliar, this is a bill, quote, “To promote prosperity, creativity, entrepreneurship, and innovation by combating the theft of U.S. property, and for other purposes,” perhaps better known by its short name, the ” Stop Online Piracy Act.” It is an interesting piece of potential law, and in brief summary, increases the responsibility of internet companies to prevent copyright theft on their domains. It also stands to reason that because this bill was sponsored by representatives working with the MPAA and RIAA, that’s who’s going to use it, though I’m sure new powers and interested parties will line up to take advantage of the bill as soon as they find out how. But I’ve got news for you: Intellectual property is dying, and there’s nothing you can do about it. Continue reading this article »
We are proud to highlight Christian Kaltepoth, who gave a fabulous presentation on PrettyFaces at WJAX/JAXCon in Munich on Wednesday, November 10th – 2011. Christan presented with Andy Bosch, who gave a short intro of URL-rewriting, what it means for applications in general, and why you should do URL-rewriting.
Key points include:
URL-rewriting can be used to create human-readable URLs, which is good for user-experience.
REST-ful URLs using keywords benefit search engine optimization (SEO)
Hiding non-essential URL information such as page extensions (.jsp, .xhtml, .do) helps protect your applications from vulnerability.
With URL-rewriting, REST-ful URLs can be applied to any new or existing application
Seizing the opportunity of a new Executive Committee (EC) under a new regime, I’d like to issue a call for reform of the Java Community Process (JCP) to allow it to produce more iterative and timely technology and live up to it’s name as a “community process”, rather than acting as the “corporate process” many believe it is today [1].
The PrettyFaces team is pleased to announce the release of PrettyFaces 3.3.0. PrettyFaces is an OpenSource Servlets extension with enhanced support for JavaServer Faces – JSF 1.1, 1.2 and 2.0 – enabling creation of bookmark-able, pretty URLs. PrettyFaces solves the “RESTful URL” problem elegantly, including features such as: page-load actions, seamless integration with faces navigation, dynamic view-id assignment, managed parameter parsing, and configuration-free compatibility with other web frameworks.
Performance improvements when running JSF 2.0 in project stage ‘development’
Regular expression performance improvements provided by Yann Simon.
Ambiguous View IDs are now resolved automatically when using pretty:mappingIds in action method navigation, <h:link> and <h:button> component outcomes
Ambiguous View IDs may now be resolved manually for outbound URL rewrites by adding ‘?com.ocpsoft.mappingId=…’ to URLs before calling HttpServletResponse.encodeURL(…)
Dynaview URLs* are now resolved during rendering of links and navigation cases, and are now as functional as traditional mappings.
Bugfixes:
Fixed bug that caused path parameter validators to be ignored (#102)
Handle java.lang.ClassFormatError during initialization of bean name resolvers (#101)
Also check Weld 1.1.x specific servlet context attribute while search for BeanManager
Mapping inheritance now working correctly for mappings using the same viewId
* – Previously, DynaView URLs would only function on inbound requests, and once the method was evaluated, the value would be processed and then abandoned. For example, when rendering <h:link /> components, users would actually see the dynaview method definition rendered as their url! That is not a good experience, so in resolving the problem, we simple evaluate the dynaview method a second time (or as many times as necessary) in order to render the desired link target. And we do this using…
