Renamed Logback Config File for Web Application. There are four frameworks frequently used for logging in Java - java.util.logging aka JUL. Apache Commons Logging aka JCL. I had "luck" to find them all used by a single web application. It was impossible to tell what component uses what logging API for what messages. To make the logging manageable I modified the code base to use SLF4J API with Logback - changes to several places in code were made and bridges were added. And then fails with JoranException.

DIY Wi-Fi Access Point on Linux. From local vendor I bought PCI Express card with Atheros. Chip complying to IEEE 802.11n. It should be versatile and well-supported. In case you are interested in the particular device, it is TP-LINK TL-WN781N. Naturally you must have some decently recent kernel and enabled support for wireless networking, your Wi-Fi chip and bridging (will be explained later). The more or less relevant config options on my machine looks this way:. Bridging Wi-Fi and Ethernet. Wpa supplic...

Maven: The Aggregator vs. The Parent. I have recently realized that even professionals working with Maven for extended period do not fully grasp the differences of Maven's aggregators and parents. The reason for that is probably that both terms are related to multi-module. Projects and that both approaches often 'meet' in single file. Multi-module projects usually have rather flat structure with a single top-level pom.xml. A top-level module serving for joining multiple modules under one roof. So we show...

Git with Attlasian Stash via SSH, on Windows. I do not know why Atlassian decided to name the thing Stash when there was Git stash, probably some "clever" marketing. I used Git for some time but just recently I had to use the SSH protocol on Windows to authenticate to Stash. Integrating Linux-born software to Windows environment is sometimes easy but that was not this case - to prevent more people to curse Git because of that, I made the following HOWTO. First of all you need to install Git. When asked f...

Using Smart Card as Keystore in Java, setup. Using a smart card as a key store promises stronger security compared to storing keys or certificates on a disk. This can be further improved by using a card reader with a PIN pad, an effective counter-measure against key loggers. This article should provide basic information how to use smart card as key store for Java applications. Application java.security.Keystore JVM PKCS11 provider PC/SC middleware CCID USB smart card reader smart card. Sun PKCS#11 provid...

Maven: Creating Executable JAR with Shade Plugin. I was pleasantly surprised by versatility of Maven shade plugin. Creating a custom-named executable JAR and bundle only the dependencies you really need is a piece of cake. The documentation is partly is online, partly in the plugin's help and provides all necessary information. Orgapache.maven.plugins /. Orgapache.maven.plugins.shade.resource.ManifestResourceTransformer. Orgbithill.example.Tool /. Links to this post. Subscribe to: Posts (Atom).

Accessing Oracle User-Defined Type with Spring JDBC. It's not so long I wrote some single-purpose utility which called a stored procedure in Oracle database. The procedure returned as its result an user-defined data type. Definition of the type looked approximately as this one:. I could have specified the mappings between Oracle object and Java class by implementing the SQLData interface. The approach supported by Spring Data. But I had only Spring JDBC. Available so I used the SqlReturnType.

Using Smart Card as Keystore in Java, signing. This is the promised sequel of the article from September 8th 2011. It does not represent the only one way how to achieve the desired result, especially when it comes to manipulation with certificates and keys certificate management. Loading Certificate into the Card. It seems that the easiest approach is to prepare the key store on disk and load it into the card when ready. For that we use mostly two tools - openssl. To manage the key store. In cert. pem.

rostislav.matl: Moving to Selenium 2 on WebDriver, Part No.1

http://rostislav-matl.blogspot.com/2011/03/moving-to-selenium-2-on-webdriver-part.html

Moving to Selenium 2 on WebDriver, Part No.1. I am in the process of trying to move code of some test to the Selenium 2 WebDriver. This is the first part of series of short articles about how to "translate" old Selenium API to the WebDriver-based one. In following, let's state that xpathLocator is Selenium 1 locator, while xpathFinder is more or less By.xpath(xpathLocator),selenium is instance of Selenium, driver is instance of WebDriver (FirefoxDriver).
