Hi, I'm starting to learn seam and i've some troubles. I've got a project with one web app and one ejb jar (like seam booking) I can deploy my ear on the server but when i want to access login page i've this error : 01:44:41,352 INFO [StartupServletContextListener] Serialization provider : class org.apache.myfaces.shared_impl.util.serial.DefaultSerialFactory 01:44:41,372 INFO [StandardContext] Container org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/extranet-backoffice] has already been started 01:44:41,379 INFO [TomcatDeployment] deploy, ctxPath=/extranet-customer, warUrl=.../tmp/deploy/extranet-customer36254-exp.war/ 01:44:41,480 INFO [StandardContext] Container org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/extranet-customer] has already been started 01:44:41,493 INFO [TomcatDeployment] deploy, ctxPath=/extranet-partner, warUrl=.../tmp/deploy/extranet-partner36255-exp.war/ 01:44:41,719 INFO [StandardContext] Container org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/extranet-partner] has already been started 01:44:41,736 INFO [TomcatDeployment] deploy, ctxPath=/internet, warUrl=.../tmp/deploy/internet36256-exp.war/ 01:44:41,833 INFO [StandardContext] Container org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/internet] has already been started 01:44:41,962 INFO [MailService] Mail Service bound to java:/Mail 01:44:51,130 INFO [MCKernelAbstraction] installing bean: jboss.j2ee:ear=assurix.ear,jar=jboss-seam-1.2.1.GA.jar,name=Dispatcher,service=EJB3 with dependencies: 01:44:51,322 INFO [EJBContainer] STARTED EJB: org.jboss.seam.core.Dispatcher ejbName: Dispatcher 01:44:51,374 INFO [MCKernelAbstraction] installing bean: jboss.j2ee:ear=assurix.ear,jar=jboss-seam-1.2.1.GA.jar,name=TransactionListener,service=EJB3 with dependencies: 01:44:51,429 INFO [EJBContainer] STARTED EJB: org.jboss.seam.core.TransactionListener ejbName: TransactionListener 01:44:51,501 INFO [MCKernelAbstraction] installing bean: jboss.j2ee:ear=assurix.ear,jar=presentation-1.0-SNAPSHOT.jar,name=LoginController,service=EJB3 with dependencies: 01:44:51,522 INFO [EJBContainer] STARTED EJB: com.assurix.presentation.extranet.backoffice.LoginController ejbName: LoginController 01:44:51,571 INFO [Http11Protocol] Starting Coyote HTTP/1.1 on http-0.0.0.0-8080 01:44:51,632 INFO [AjpProtocol] Starting Coyote AJP/1.3 on ajp-0.0.0.0-8009 01:44:51,691 INFO [ServerImpl] JBoss (Microcontainer) [5.0.0.Beta1 (build: CVSTag=https://svn.jboss.org/repos/jbossas/tags/JBoss_5_0_0_Beta1 date=200611191849)] Started in 1m:48s:699ms 01:44:53,708 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception org.apache.jasper.JasperException: /index.jsp(15,15) According to TLD or attribute directive in tag file, attribute value does not accept any expressions at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:40) at org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:406) at org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:147) at org.apache.jasper.compiler.Validator$ValidateVisitor.checkXmlAttributes(Validator.java:1044) at org.apache.jasper.compiler.Validator$ValidateVisitor.visit(Validator.java:818) Index.jsp : <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %> <%@ taglib uri="http://jboss.com/products/seam/taglib" prefix="s" %> Login New User <f:view> <h:form> <s:validateAll> Username <h:inputText value="#{backOfficeLoginController.username}"/> Password <h:inputSecret value="#{backOfficeLoginController.password}"/> </s:validateAll> <h:messages/> <h:commandButton type="submit" value="Login" action="#{backOfficeLoginController.login}"/> </h:form> </f:view> My bean : @Stateful @Name("backOfficeLoginController") public class LoginController extends PresentationController implements LoginControllerInterface { @Logger private Log log; private LoginModule loginModule; .... } My environment : JBoss 5.0.0Beta1 Maven2 Seam 1.2.1GA MyFaces 1.1.4 (install as manifest dependency for webapp) I suppose that my ejb well deployed (see jboss log) but my main supposition is that the JSF/JSP engine produce the error. Do you have any ideas where the problem comes from ? I will try to put directly the myfaces jar directly in WEB-INF/lib to see wha happen.
