Problem with Ajax
Hello all
I'm relative new in Seam and have a problem with my web application.
The situation:
With the help of the following website (http://docs.jboss.com/seam/latest/reference/en-US/html/remoting.html ) and my book Jboss Seam
I tried to add ajax in my application, but nothings happend. I have absolut no idea where the mistake is. I hope anybody here can help me.
I'd like to call a function in my stateful-bean if a file d lost the focus......thats all.
Here ist my web.xml:
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" 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"> <context-param> <param-name>javax.faces.CONFIG_FILES</param-name> <param-value>/WEB-INF/navigation.xml</param-value> </context-param> <!-- Seam --> <listener> <listener-class>org.jboss.seam.servlet.SeamListener</listener-class> </listener> <servlet> <servlet-name>Seam Resource Servlet</servlet-name> <servlet-class>org.jboss.seam.servlet.SeamResourceServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>Seam Resource Servlet</servlet-name> <url-pattern>/seam/resource/*</url-pattern> </servlet-mapping> <filter> <filter-name>Seam Filter</filter-name> <filter-class>org.jboss.seam.web.SeamFilter</filter-class> </filter> <filter-mapping> <filter-name>Seam Filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- MyFaces --> <!-- <listener> <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class> </listener> --> <context-param> <param-name>javax.faces.STATE_SAVING_METHOD</param-name> <param-value>client</param-value> </context-param> <context-param> <param-name>facelets.DEVELOPMENT</param-name> <param-value>true</param-value> </context-param> <context-param> <param-name>javax.faces.DEFAULT_SUFFIX</param-name> <param-value>.xhtml</param-value> </context-param> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- Faces Servlet Mapping --> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.seam</url-pattern> </servlet-mapping> </web-app>
