    <p>I've looked through all similar Qs on stackoverflow but it didn't help, sorry. The main difference I have from all of them is that I got EMPTY action name in error message. Googling didn't help :( Hope someone just could give a hint where to look for the source of the problem. thx</p> <p>message:</p> <pre><code> Stacktraces There is no Action mapped for namespace [/] and action name [] associated with context path [/struts]. - [unknown location] com.opensymphony.xwork2.DefaultActionProxy.prepare(DefaultActionProxy.java:185) org.apache.struts2.impl.StrutsActionProxy.prepare(StrutsActionProxy.java:63) org.apache.struts2.impl.StrutsActionProxyFactory.createActionProxy(StrutsActionProxyFactory.java:39) com.opensymphony.xwork2.DefaultActionProxyFactory.createActionProxy(DefaultActionProxyFactory.java:58 .................. </code></pre> <p>struts.xml:</p> <pre><code> &lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"&gt; &lt;struts&gt; &lt;constant name="struts.devMode" value="true" /&gt; &lt;package name="default" namespace="/*" extends="struts-default"&gt; &lt;action name="login" class="training.struts.action.LoginAction"&gt; &lt;result&gt;login.jsp&lt;/result&gt; &lt;/action&gt; &lt;/package&gt; &lt;/struts&gt; </code></pre> <p>web.xml:</p> <pre><code> &lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"&gt; &lt;display-name&gt;Struts Lab&lt;/display-name&gt; &lt;filter&gt; &lt;filter-name&gt;struts2&lt;/filter-name&gt; &lt;filter-class&gt;org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter&lt;/filter-class&gt; &lt;/filter&gt; &lt;filter-mapping&gt; &lt;filter-name&gt;struts2&lt;/filter-name&gt; &lt;url-pattern&gt;/*&lt;/url-pattern&gt; &lt;/filter-mapping&gt; &lt;!-- Spring Config --&gt; &lt;context-param&gt; &lt;param-name&gt;contextConfigLocation&lt;/param-name&gt; &lt;param-value&gt; /WEB-INF/springServlet/appServlet/mvc-servlet.xml, /WEB-INF/db/db-cfg.xml, /WEB-INF/springServlet/application-security.xml &lt;/param-value&gt; &lt;/context-param&gt; &lt;listener&gt; &lt;listener-class&gt;org.springframework.web.context.ContextLoaderListener&lt;/listener-class&gt; &lt;/listener&gt; &lt;servlet&gt; &lt;servlet-name&gt;mvc&lt;/servlet-name&gt; &lt;servlet-class&gt;org.springframework.web.servlet.DispatcherServlet&lt;/servlet-class&gt; &lt;init-param&gt; &lt;param-name&gt;contextConfigLocation&lt;/param-name&gt; &lt;param-value&gt;/WEB-INF/springServlet/appServlet/mvc-servlet.xml&lt;/param-value&gt; &lt;/init-param&gt; &lt;load-on-startup&gt;1&lt;/load-on-startup&gt; &lt;/servlet&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;mvc&lt;/servlet-name&gt; &lt;url-pattern&gt;/&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; &lt;!-- Spring Security --&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;!-- *** --&gt; &lt;welcome-file-list&gt; &lt;welcome-file&gt;login.jsp&lt;/welcome-file&gt; &lt;welcome-file&gt;index.jsp&lt;/welcome-file&gt; &lt;/welcome-file-list&gt; &lt;/web-app&gt; </code></pre> <p>well..image is impossible so the project structure is:</p> <pre><code>src/main/java ----+training.struts.action.LoginAction.java src/main/webapp ----+WEB-INF --------+classes -----------+struts.xml --------+db -----------+db-cfg.xml --------+springServlet -----------+appServlet ---------------+mvc-servlet.xml -----------+application-security.xml --------+index.jsp --------+login.jsp --------+web.xml </code></pre> <p><strong>UPDATE: So sad to be stupid =( I've moved my login.jsp from WEB-INF to webapp root and that solved the problem.</strong></p> <p><strong>UPDATE2:</strong> I've made some investigation: if I remove "welcome-file-list" block from web.xml, container will look for "index.jsp" in webapp root to show as first view on application running. If I delete "index.jsp" then I'll got the identical exception message: <em>There is no Action mapped for namespace [/] and action name [] associated with context path [/struts]</em></p> <p>So in my opinion if you have empty action name in error message with correct xml settings for struts, the first step should be start-up JSP availability checking.</p> <p>Cheers, guys.</p>

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).
