Spring-WS documentation says you can use a Jaxb object as parameter or return type, provided that it is annotated with javax.xml.bind.annotation.XmlRootElement , or is an instance of javax.xml.bind.JAXBElement . But that's a lot easier said than done! For example, if sayHelloResponse is defined as:
<xs:element name="sayHelloResponse" type="tns:sayH... then the JAXB generated class is not annotated with XmlRootElement , therefore, unusable for Spring-WS. You have to define the type as: <xs:element name="sayHelloResponse"> <xs:compl... in order to generate a type annotated with XmlRootElement . But that is not always possible. Alternatively, you can use the Maven plugin maven-jaxb2-plugin with the jaxb2-basics-annotate plugin (yes, plugin inside plugin) to inject the XmlRootElement annotation into the generated JAXB class. This is the pom: <project xmlns="http://maven.apache.org/POM/4.0.0"... and the binding file: <?xml version="1.0" encoding="UTF-8" standalone="y......

The C function getsockopt lets you get the error codes with the option SO_ERROR . The possible error numbers are defined in the global errno.h . The relevant values are:
#define ETIMEDOUT 110 /* Connection timed out */

svn does not automatically substitute keywords like $Id$ . To enable keyword substitution, you have to enable it with propset :
$ svn propset svn:keywords "Id" README.txt
To enable keyword substitution for all files:
$ svn propset -R svn:keywords "Id" .
The above examples enabled substitution for $Id$ only. Each keyword must be explicitly listed to be substituted. The keywords recognized by svn are:
svn:keywords - Keywords to be expanded. Val...

You can submit a form via Ajax by the jQuery Form Plugin . There are two main methods:
ajaxForm : prepares a form for Ajax submit.
Example:
$('#myFormId').ajaxForm({
target: ...
When the form is submitted, it is sent via Ajax.
ajaxSubmit : submit a form via Ajax.
Example:
$('#myForm2').submit(function() {

jQuery Form Plugin is not in the core jQuery API, so you have to include an additional JS file:
<head>
<script type="text/javascript" ...

Our custom tag, as implemented in the previous note , is broken when a template is used.
Create a template file ( home-template.xhtml ):

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...

In the simple taglib example , I used a tag handler class to implement a taglib. This is an example to implement a taglib with a UI component. The purpose is to use a custom tag to split a string and print each part in a separate paragraph, i.e., print
<p>john</p> <p>steve</p> <p>mike</p> with custom tag <my:foreach> : <my:foreach var="who" value="john steve mike"> ... These are the files: pom.xml <project xmlns="http://maven.apache.org/POM/4.0.0"... src/main/java/com/example/UIForeash.java : package com.example; import java.io.IOExcep... src/main/resources/META-INF/faces-config.xml : <?xml version="1.0" encoding="UTF-8"?> <faces-c... src/main/resources/META-INF/foreach.taglib.xml : <?xml version="1.0" encoding="UTF-8"?> <facelet... How to use: Put the JAR file generated by the above project in the WEB-INF/lib folder of the web app. If the web app is a Maven project, just add the taglib project as a dependency:...

Summarized from The C Book : There are essentially two types of object in C: the internal and external objects. Anything declared outside a function is external; anything inside one, including its formal parameters, is internal. Since no function can be defined inside another, functions are always external. All function declarations implicitly have the extern keyword stuck in front of them, whether or not you put it there. These two declaearions are equivalent:
void some_function(void); extern void some_func... The term linkage is used to describe the accessibility of objects from one file to another. There are three types of linkage: external , internal , and no linkage . Type of linkage Type of object Accessibility external external Across files, througout the program internal external Within...
