It's normal practice to import types from an external xsd file in WSDL like this:
<wsdl:types> <xsd:schema xmlns:xsd="htt... When you use <dynamic-wsdl> and have Commons XMLSchema on the class path, Spring-WS inlines the xsd in the wsdl. But that doesn't happen when you use <static-wsdl> . You can define a SimpleXsdSchema bean to expose the xsd: <?xml version="1.0" encoding="UTF-8"?> <beans x... where the bean id "hello" should match the schemaLocation attribute in the WSDL (without the .xsd suffix). But note that the SimpleXsdSchema does not inline the xsd. It only makes the xsd available via an HTTP URL. Alternatively, you can simply put the xsd file under the content directory of the webapp (just link any CSS or JavaScript). Anyway, that's a lot of manual...

This is a step-by-step guide to create a "contract-first" web service with Apache CXF. It's a lot easier than doing the same thing with Spring-WS. The project uses standard Maven directory layout. Define the data types ( src/main/resources/hello.xsd ):
<xs:schema xmlns:xs="http://www.w3.org/200... Define the service ( src/main/resources/hello.wsdl ): <?xml version='1.1' encoding='UTF-8'?> <wsdl:de... Create pom.xml : <project xmlns="http://maven.apache.org/POM/4....

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......

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...

Create a jax-ws web service with Spring, Apache CXF and Maven.
Create the pom.xml :
<project xmlns="http://maven.apache.org/POM/4.0.0"...
Create the web service interface ( src/main/java/jaxws/JaxwsHello.java ):
package jaxws;
import javax.jws.WebService;...
Implement the web service ( src/main/java/jaxws/JaxwsHelloImpl.java ):
package jaxws;
import javax.jws.WebService;...
Create src/main/webapp/WEB-INF/cxf-servlet.xml :
<?xml version="1.0" encoding="UTF-8"?>
<beans x...
Register the CXF servlet in src/main/webapp/WEB-INF/web.xml :
<?xml version="1.0" encoding="UTF-8"?>
<web-app...
Build:
mvn package
The resulting WAR file can be deployed to any servlet container (for example, Tomcat).

This is probably the easiest way to create a web service in JAX-WS. There are no external dependencies other than Java EE. Assuming that you build the web service as a webapp (say jaxws-example.war), the pom.xml can be as simple as:
<project xmlns="http://maven.apache.org/POM/4.0.0"... You can implement and deploy the web service in 3 easy steps: Code the service as a POJO (annotate class to expose it as a web service) package jaxws; import javax.jws.WebMethod; ... Declare the POJO as a servlet in WEB-INF/web.xml : <?xml version="1.0" encoding="UTF-8"?> <web-app... Build the webapp, and deploy the resulting war: mvn package The only catch is, this only works for a Java EE 5+ compliant container such as WebLogic or JBoss. It does not work for a simple servlet...

In JSP you output the web application context path with:
${pageContext.request.contextPath}
Facelets are not JSPs, and there's no pageContext . So the above does not work.
But in facelets you can use request directly:
${request.contextPath}
For example, a link to the root URL:
<a href="${request.contextPath}">Home</a>
Servlet request URL:
<h2>#{request.requestURL}</h2>

This example gets the annotation attributes of of a web service client generated by JAX-WS RI.
The generated web service client looks like this:
import javax.xml.ws.Service;
import javax.xml.w...
This is how to get the attributes for annotation @WebServiceClient :
WebServiceClient wsc = MyTestWebService.class.getA...
Note that even though name , targetNamespace and wsdlLocation are attributes, you get them using a method call.
Also, annotations are available at runtime only when they have RetentionPolicy.RUNTIME .

To delete a cookie in Java servlet API, call Cookie.setMaxAge(0) . According to Servlet API JavaDoc :
A positive value indicates that the cookie will expire after that many seconds have passed. Note that the value is the maximum age when the cookie will expire, not the cookie's current age.
A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted.
