seam remoting works fine on jboss4.2 but not jboss5.1

[thera]

we use seam remoting in out application(seam and iceface), it works fine on jboss4.2.1 always, but now we upgraded to jboss5.1, we had below error and that remoting function doesn't work on jboss5.1.

the error looks like this:

10:36:10,225 ERROR [InterfaceGenerator] Component not found: [ColumnBean]
10:36:10,225 ERROR [Remoting] Error

the web.xml configured like this:

<servlet>
     <servlet-name>Seam Resource Servlet</servlet-name>
     <servlet-class>org.jboss.seam.servlet.SeamResourceServlet</servlet-class>
</servlet>

on cust.xhtml I added below codes:

<s:remote include="ColumnBean"/>

Java codes Class ColumnBean

@Name("trColumnCustomizerBean")
@Scope(ScopeType.SESSION)
public class ColumnCustomizerBean

@WebRemote
public void updateDisTxt(String newDisTxt) {
   //do something
}

in addition, we use seam 2.2.0.

the web.xml I added these lines:

<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>

[thera]

Java codes Class ColumnBean

@Name("ColumnBean")
@Scope(ScopeType.SESSION)
public class ColumnBean {

  @WebRemote
  public void updateDisTxt(String newDisTxt) {
     //do something
  }

}

I would answer my own question.

because we have 2 war in our application.

we resolved it by removeing these lines in web.xml in another war which is not using seam.

<listener>
        <listener-class>org.jboss.seam.servlet.SeamListener</listener-class>
</listener>

one war which is not using seam overides the war which is using seam, so it can't find my bean.

but why it works well on jboss4.2 but get such error on jboss5.1.....
