[jboss-user] [JBoss Seam] - Re: Step-by-Step Seam Getting Started Guide

More findings..

1. seam.sh is missing one more parameter (shown below)

if [ "${seamtask}" = new-wtp-project ] 
	then
		ant new-wtp-project -Dproject.name=${projectname}
fi

2. Using "new-wtp-project" parameter actually works and creates correct ejb-jar.xml like below..

<ejb-jar>
   <assembly-descriptor>
      <interceptor-binding>
         <ejb-name>*</ejb-name>
         <interceptor-class>org.jboss.seam.ejb.SeamInterceptor</interceptor-class>
      </interceptor-binding>
   </assembly-descriptor>
</ejb-jar>

Using "scaffold-wtp-project" does not work since it creates the ejb-jar.xml below..

<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar id="ejb-jar_ID" version="2.1" 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/ejb-jar_2_1.xsd">
	<display-name>
	sampleEJB</display-name>
</ejb-jar>

That needs to be corrected I believe..

3.  After fixing the problem #2, sample project successfully deployed but gave the error below.. 

02:23:01,632 WARN  [ServiceController] Problem creating service jboss.j2ee:service=EJB3,module=sampleEJB.jar
java.lang.RuntimeException: Interceptor class not found: org.jboss.seam.ejb.SeamInterceptor

Checking the web.xml (of sample) revealed what is below..

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" 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">
	<display-name>
	sampleWeb</display-name>
	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>default.html</welcome-file>
		<welcome-file>default.htm</welcome-file>
		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>
</web-app>

However, the blank project had the correct web.xml shown below..

<?xml version="1.0" ?>
<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">

    </context-param>

    <filter-mapping>
        <filter-name>Seam Redirect Filter</filter-name>
        <url-pattern>*.seam</url-pattern>
    </filter-mapping>

    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>*.seam</url-pattern>
    </servlet-mapping>                 
</web-app>

However correcting this problem got me the error below..

02:44:45,210 ERROR [[/sampleWeb]] Error configuring application listener of class org.jboss.seam.servlet.SeamListener
java.lang.ClassNotFoundException: org.jboss.seam.servlet.SeamListener

So I compared the classpath of both web apps (blank and sample)..

blank had "JBOSS 4.0" library group, sample did not.
blank had 5 jars under "Web App Libraries", sample none.

It is no wonder sample project does not work at all..

4. I don't understand why in image http://wiki.jboss.org/wiki/attach?page=JBossSeamGettingStartedGuideStep4%2Ffigure-4.7.png, sampleEJB project does not show the error indicator (red cross). At this point it generated the incorrect ejb-jar.xml and it must show the error indicator.

Later the error indicator is visible in image http://wiki.jboss.org/wiki/attach?page=JBossSeamGettingStartedGuideStep5%2Ffigure-5.5.png. So was there an error or not?

Red cross magically disappears in image http://wiki.jboss.org/wiki/attach?page=JBossSeamGettingStartedGuideStep5%2Ffigure-5.7.png. 



I am baffled.. Why on earth this seam-gen thingy creates a perfect sample project for some people yet does not work for me..

Maybe it is the late hour.. I need to check everything with fresh eyes in the morning.. :)
