The default extension for JSF facelet files is .xhtml, which looks so out-of-date these days. I wanted to change the extension from .xhtml to .html, to make it look more modern, even though I still use JSF xhtml in reality. This didn't work ( web.xml ): <servlet-mapping> <servlet-name>Faces Ser... Using the servlet-mapping config without the context-param works, given that the actual file extensions are still .xhtml . But the caveat is, if you request the .xhtml file directly, it will be sent to the browser unprocessed. This worked: <servlet-mapping> <servlet-name>Faces Ser... I'm using myfaces 2.1.11.

After a user resets a password, I want to force the user to change the password before she gets access to secured content. This is usually done with a servlet filter. But with Spring MVC, you can also use a HandlerInterceptor . According to Spring JavaDoc: HandlerInterceptor is basically similar to a Servlet 2.3 Filter, but in contrast to the latter it just allows custom pre-processing with the option of prohibiting the execution of the handler itself, and custom post-processing. Filters are more powerful, for example they allow for exchanging the request and response objects that are handed down the chain. Note that a filter gets configured in web.xml, a HandlerInterceptor in the application context. As a basic guideline, fine-grained handler-related preprocessing tasks are candidates...

Junit does not support specifying execution order of tests until 4.11. The methods were simply invoked in the order returned by the reflection API. So, the tests are executed in a unspecified but deterministic order, i.e., you have no control over the order of execution, but if you repeat the tests, they are run in the same sequence each time. For version 4.11, you can specify the order with the FixMethodOrder annotation: import org.junit.runners.MethodSorters; imp... From the release notes : Test execution order By design, JUnit does not specify the execution order of test method invocations. Until now, the methods were simply invoked in the order returned by the reflection API. However, using the JVM order is unwise since the Java platform does not specify...

This example came from the jQuery validation documentation. The required rule can be used to validate a required selection box when you set the value of the first option to empty. <!DOCTYPE HTML> <html> <head> <scrip... The error message is the title since no error message is specified. A more fully defined validation check would look like this: $('#my-form').validate({ errorElement: "p", ...

Step 1: Repackage a web app as EAR A Java EE application is a multimodule Maven project. At the very least you'll need to package a WAR and an EAR. To get started, I'll simply re-package the simple webapp as an EAR. Create a directory named javaee-app Copy the webapp from here to javaee-app . Rename struts1app to webapp . Create pom.xml under javaee-app : <project> <modelVersion>4.0.0</modelVersion>... Create a directory named ear under javaee-app . Create pom.xml under ear : <project> <modelVersion>4.0.0</modelVersion>... Modify pom.xml in the webapp directory so that it looks like this: <project> <modelVersion>4.0.0</modelVersion> ... Build with " mvn package " in the javaee-app directory. You can see that ear-1.0.ear is successfully generated in javaee-app/ear/target . Maven successfully resolves dependencies between the sub-projects....

More like assign a second ip address to the same nic, instead of a virtual nic. Multiple IP addresses can be assigned to the same NIC, but all IP addresses must be on the same subnet - otherwise some IP addresses will not be accessible. From command line, assign IP address 192.168.0.2 to alias eth0:0 : sudo ifconfig eth0:0 192.168.0.2 netmask 255.255.2... But IP addresses added this way are not persistent. They are lost whent he OS is restarted. To make the additions persistent: For Fedora: $ su - # cd /etc/sysconfig/network-scripts/ ... The contents of ifcfg-eth0:0 should look like this: DEVICE=eth0:0 IPADDR=192.168.0.2 NETMASK=255... Restart network: # service network restart For Ubuntu: $ sudo vi /etc/network/interfaces Append this to the file: auto eth0:0 iface eth0:0 inet static name Et......

The Android unit test framework is based on JUnit 3 , not JUnit 4. Test cases have to extend junit.framework.TestCase or a subclass (such as android.test.InstrumentationTestCase ). Tests are identified by public methods whose name starts with test , not methods annotated with @Test (as in JUnit 4). An Android test suite is packaged as an APK, just like the application being tested. To create a test package, first you need to identify the application package it is testing. Google suggests to put the test package source in a directory named tests/ alongside the src/ directory of the main application. At runtime, Android instrumentation loads both the test package and the application under test into the same process. Therefore, the tests can invoke methods on...
