Ok, I’ve run across my first StackOverflowError since joining this site, I figured this is a must post :-). My environment is Seam 2.0.1.GA, JBoss 4.2.2.GA and I’m using JSF. I am in the process of converting from a facelets view to JSP to take advantage of some existing JSP tags used on our existing site. I changed the faces-config.xml and the web.xml configuration files and started to receive the following error when trying to render a jsp page. Anyone have any thoughts?

2008-09-17 09:45:17,537 DEBUG [org.jboss.seam.contexts.FacesLifecycle] Begin JSF request for /form_home.jsp 2008-09-17 09:45:17,587 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/].[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw exception java.lang.StackOverflowError at org.apache.catalina.core.ApplicationHttpRequest.getAttribute(ApplicationHttpRequest.java:210) at org.apache.catalina.core.ApplicationHttpRequest.getAttribute(ApplicationHttpRequest.java:222) at org.apache.catalina.core.ApplicationHttpRequest.getAttribute(ApplicationHttpRequest.java:222) at org.apache.catalina.core.ApplicationHttpRequest.getAttribute(ApplicationHttpRequest.java:222) …

My faces-config.xml file is now empty with no FaceletsViewHandler:

<?xml version='1.0' encoding='UTF-8'?> <faces-config version='1.2' xmlns='http://java.sun.com/xml/ns/javaee'  xmlns:xi='http://www.w3.org/2001/XInclude'  xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'  xsi:schemaLocation='http://java.sun.com/xml/ns/javaee      http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd'>  </faces-config>

And my Web.xml file:

<?xml version='1.0'?> <web-app version='2.5' xmlns='http://java.sun.com/xml/ns/javaee'  xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'  xsi:schemaLocation='http://java.sun.com/xml/ns/javaee    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd'>  <!-- Ajax4jsf -->  <context-param>   <param-name>org.richfaces.SKIN</param-name>   <param-value>blueSky</param-value>  </context-param>   <!-- Seam -->  <listener>   <listener-class>org.jboss.seam.servlet.SeamListener</listener-class>  </listener>    <filter>   <filter-name>Seam Filter</filter-name>   <filter-class>org.jboss.seam.servlet.SeamFilter</filter-class>  </filter>   <filter-mapping>   <filter-name>Seam Filter</filter-name>   <url-pattern>*.jsp</url-pattern>  </filter-mapping>   <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>  <!-- Seam end -->    <!-- JSF -->  <context-param>         <param-name>javax.faces.DEFAULT_SUFFIX</param-name>         <param-value>.jsp</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>  <servlet-mapping>     <servlet-name>Faces Servlet</servlet-name>     <url-pattern>*.jsp</url-pattern>   </servlet-mapping>

  1. I was able to figure out this problem. Apparently you can not configure web.xml to have the same param-value of .jsp for Javax.faces.DEFAULT_SUFFIX as the Faces Servlet url-pattern (*.jsp). If you change your url-pattern to .jspx or to /whateverdirnameyouwant/ the application starts up with no stack overflow errors. (note: the key is that DEFAULT_SUFFIX and Faces Servlet url-pattern cannot be the same regardless of what they are.) Hope this helps anyone else that experiences this specific problem.
