This note lists some of the different behaviors I found using different JSF implementations. In the simple JSF facelet example, I used Sun's reference implementation version 2.0.0-RC: <dependency> <groupId>javax.faces</gro... With this version, the DOCTYPE declaration is dropped when the page is rendered. It doesn't matter what DOCTYPE you declare in your templates, the facelet engine simply drops it. The problem with this is, your page is always displayed in quirks mode , despite your intentions to require standards compliant mode. The DOCTYPE problem is fixed in release 2.0.2-FCS . Change the dependency in pom.xml to: <dependency> <groupId>javax.faces</gro... and test again, you'll find that DOCTYPE is faithfully passed over to the browser (view source at browser). You can delete the DOCTYPE declaration in the xhtml template...

When you run automated Android tests with Eclipse or from the command line, you get text output, which isn't good for reporting purposes. If you run a large set of test cases with automated build, the text report isn't very helpful. Fortunately, Android CTS generates test reports in XML with accompanying XSL to make it look nice in a browser. To run your own tests with Android CTS: Download Android CTS Make a new directory MyRepository under android-cts , alongside the existing repository directory. Copy host_config.xml from repository to MyRepository Create directory plans under MyRepository , add a test plan ( MyTests.xml ): <?xml version="1.0" encoding="UTF-8"?> <TestPla...

The first time you sign in with your Google Account on an Android phone, you are asked to set up "Backup & Restore". But it's somewhat scary since it doesn't tell you what's backed up and how to restore. On the phone, backup & restore is managed by Privacy Settings . According to Google, these things are backed up to Google servers: Your wifi passwords Browser bookmarks A list of applications you've installed The words you've added to the dictionary used by the onscreen keyboard Most of the settings you configure with the Settings application Third party applications may backup their data if they support this feature. You have to check each application to find out. Restoration happens automatically when you sign in with the...

A task that a Java developer does so frequently is to find out where a certain class can be found - to resolve compilation errors, classpath issues, or version conflicts of the same class introduced by multiple class loaders. A long while back I wrote a simple Perl script to perform the task. Later I was informed that there are Swing based Jar Browser and Jars Browser . Then, there are a couple of shell one-liners: # one liner 1 find -name "*.jar" -print0 | xarg... But all of them share the same problem: if a class is in a jar nested in another jar, it cannot be found. Such is the case for a class inside a jar under the WEB-INF/lib directory of a...

I tried to find a GZIP compression servlet filter to compress a large log file that we send down to the browser. Most of the implementations I found were overly complicated and many buggy. This is a simple implementation that worked for me. The filter: package filter.demo; import java.io.*; i... Config web.xml : <filter> <filter-name>gzipFilter</filte... The ugly anonymous inner class could have been avoided if the servlet API did not insist on ServletResponse.getOutputStream returning the bogus ServletOutputStream class (instead of the plain OutputStream ). Additional Note: In an earlier version of this filter, the gzip headers were added in doFilter , like this: // This is NOT good! if (supportsGzip) { ... It turned out that the ServletResponse methods sendError bypasses the gzip...

You were tempted by "my fun cards" and installed "my web search" on your computer. Although some people say "my web search" is harmless, but still it behaved scary. So you want to uninstall it. You click the "Add/Remove Programs" and removed the "my web search" toolbar. But then when you type in things in the Firefox address bar you find that it still brings up "my web search"! Here's how to get rid of it: Enter "about:config" in the address bar (and promise that you'll be careful). Enter "myweb" in the filter box Reset browser.search.selectedEngine and keyword.URL , extensions.mywebsearch.openSearchURL , extensions.mywebsearch.prevKwdEnabled , and extensions.mywebsearch.prevKwdURL . The extensions.mywebsearch.* settings will be removed after Firefox restart. The parameter that affects the address bar search is keyword.URL...

This is a script to tail a log file through the web browser. It uses AJAX, apache web server, mod_python, UNIX utilities tail (requires the --lines switch) and wc . The log file may reside on the web server or any other host accessible from the web server through SSH. Although it's written in python, it should be easy to port to other languages such as Perl. Apache httpd.conf : LoadModule python_module modules/mod_python.so ... Python script: import time, os from os.path import basename ...
