    <p>I am developing my first application in spring security. My applicationContext-security.xml file looks like this:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;!-- - Namespace-based OpenID configuration --&gt; &lt;b:beans xmlns="http://www.springframework.org/schema/security" xmlns:b="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"&gt; &lt;http&gt; &lt;intercept-url pattern="/**" access="ROLE_USER"/&gt; &lt;intercept-url pattern="/index.xhtml*" filters="none"/&gt; &lt;logout/&gt; &lt;openid-login login-page="/index.xhtml" authentication-failure-url="/index.xhtml?login_error=true"&gt; &lt;attribute-exchange&gt; &lt;openid-attribute name="email" type="http://schema.openid.net/contact/email" required="true" count="2"/&gt; &lt;openid-attribute name="name" type="http://schema.openid.net/namePerson/friendly" /&gt; &lt;/attribute-exchange&gt; &lt;/openid-login&gt; &lt;remember-me token-repository-ref="tokenRepo"/&gt; &lt;/http&gt; &lt;b:bean id="tokenRepo" class="org.springframework.security.web.authentication.rememberme.InMemoryTokenRepositoryImpl" /&gt; &lt;authentication-manager alias="authenticationManager"/&gt; &lt;user-service id="userService"&gt; &lt;user name="http://user.myopenid.com/" authorities="ROLE_SUPERVISOR,ROLE_USER" /&gt; &lt;/user-service&gt; &lt;/b:beans&gt; </code></pre> <p>and Web.xml file is:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4"&gt; &lt;display-name&gt;Spring Security OpenID Demo Application&lt;/display-name&gt; &lt;context-param&gt; &lt;param-name&gt;contextConfigLocation&lt;/param-name&gt; &lt;param-value&gt; /WEB-INF/applicationContext-security.xml &lt;/param-value&gt; &lt;/context-param&gt; &lt;context-param&gt; &lt;param-name&gt;log4jConfigLocation&lt;/param-name&gt; &lt;param-value&gt;/WEB-INF/classes/log4j.properties&lt;/param-value&gt; &lt;/context-param&gt; &lt;context-param&gt; &lt;param-name&gt;webAppRootKey&lt;/param-name&gt; &lt;param-value&gt;openid.root&lt;/param-value&gt; &lt;/context-param&gt; &lt;filter&gt; &lt;filter-name&gt;springSecurityFilterChain&lt;/filter-name&gt; &lt;filter-class&gt;org.springframework.web.filter.DelegatingFilterProxy&lt;/filter-class&gt; &lt;/filter&gt; &lt;filter-mapping&gt; &lt;filter-name&gt;springSecurityFilterChain&lt;/filter-name&gt; &lt;url-pattern&gt;/*&lt;/url-pattern&gt; &lt;/filter-mapping&gt; &lt;listener&gt; &lt;listener-class&gt;org.springframework.web.context.ContextLoaderListener&lt;/listener-class&gt; &lt;/listener&gt; &lt;listener&gt; &lt;listener-class&gt;org.springframework.web.util.Log4jConfigListener&lt;/listener-class&gt; &lt;/listener&gt; &lt;welcome-file-list&gt; &lt;welcome-file&gt;faces/index.xhtml&lt;/welcome-file&gt; &lt;/welcome-file-list&gt; &lt;/web-app&gt; </code></pre> <p>Clean and Build of the application is successful, but when I try to deploy the application jetty 7 gives me following error:</p> <blockquote> <p>SEVERE: Context initialization failed<br> org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [<a href="http://www.springframework.org/schema/security]">http://www.springframework.org/schema/security]</a><br> Offending resource: ServletContext resource [/WEB-INF/applicationContext-security.xml]<br> at org.springframework.beans.factory.parsing.FailFastProblemReporter.error(FailFastProblemReporter.java:68)<br> at org.springframework.beans.factory.parsing.ReaderContext.error(ReaderContext.java:85)<br> at org.springframework.beans.factory.parsing.ReaderContext.error(ReaderContext.java:80) </p> </blockquote> <p>Tried everything but can't solve this error. Any help would be appreciated.</p> <p><strong>EDIT</strong> I tried added 3.0.2 version of the Spring-Security and got this:</p> <blockquote> <p>Context initialization failed<br> org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 13 in XML document from ServletContext resource [/WEB-INF/applicationContext-security.xml] is invalid;<br> nested exception is org.xml.sax.SAXParseException; lineNumber: 13; columnNumber: 11; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'http'. at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:396)<br> at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:334</p> </blockquote>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
