Redsocks is a transparent socks/proxy redirector. You use iptables to redirect TCP traffic to redsocks, redsocks will forward to upstream SOCKS4, SOCKS5 or HTTPS proxy server. Once set up, the redirection is system wide, so you don't have to set up proxy for each individual application. It is useful when you have to use a SOCKS or proxy server to make the connection but the application does not support proxy settings (for example, the Android browser). Linux/iptables, OpenBSD/pf and FreeBSD/ipfw are supported. Sample configuration file : base { log_debug = off; log_info = off; ... According to the project home page , redsocks is used by ProxyDroid to provide system-wide proxy on rooted Android devices.

Spring MVC 3.1 can send either JSON or HTML response on the same URL, depending on the type of response requested. With this mechanism, a page can be sent when directly requested from a link, but a JSON response can be sent in response to an AJAX request. This is the controller code: package com.example; import java.util.Map; ... In the above example, JSON response will be sent when the HTTP request contains header "Accept: application/json". HTML response will be sent then the header is "Accept: */*", or "Accept: text/html", or anything else. You can add a limitation that the HTML response does not produce "application/json". But then the question is which response will be sent when the HTTP header is "Accept: */*"? Both methods will...

Our custom tag, as implemented in the previous note , is broken when a template is used.

Then request the page with URL: http://localhost:8080/facelet-demo/home.jsf?name=Jack . You'll find that our hello tag works inside ui:repeat but fails to get the value defined by ui:param ! What's the problem? Our hello tag implementation evaluated the EL with the wrong EL context! This is the corrected implementation: package com.example; import java.io.IOExcep...

This is a simple example to demonstrate the templating power of JSF facelets. If you've used struts tiles before, you'll recognize the simplicity of templating with facelets. I've stripped out everything else except the pages themselves, just to put our focus on facelets. This is a Maven based project, and you need Tomcat (or any servlet container) to run the resulting webapp. To begin with this is the list of files: ./pom.xml ./src/main/webapp/home.xhtml ./src... I left faces-config.xml in there for completeness sake, it may not be needed. The Maven POM ( pom.xml ): <?xml version="1.0" encoding="UTF-8"?> <project... Web app configuration ( WEB-INF/web.xml ): <?xml version="1.0" encoding="UTF-8"?> <web-app...

Facelet templates can be nested, for example, a page can use a template which inherits from another template. To demonstrate this, let's start from the simple example and make these additions: Add a place holder for CSS style sheets in WEB-INF/templates/default.xhtml : <h:head> <title>Facelets Template Demo</tit... Add a derivative template ( WEB-INF/templates/default-style.xhtml ) which provides CSS: <?xml version="1.0" encoding="UTF-8"?> <ui:comp... Add a page that uses the styled template ( home-style.xhtml ): <?xml version="1.0" encoding="UTF-8"?> <ui:comp... The only difference between this file and home.xhtml is the template being used. Compare the display of the pages home.xhtml and home-style.xhtml .

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...

Three elements are needed for this to work: security-constraint with the url-pattern to protect, login-config for the type of authentication method to use, and security-role for the role name(s) used in the security-constraint .
