That's really stupid ;-)
But now there's the next error:
I think the use Bean Tag is wrong, because the Error ist:
Generated servlet error:
[javac] Compiling 1 source file
C:\tomcatWapen\work\Standalone\localhost\wapen\form\listpersons_jsp.java:92:
person is already defined in
_jspService(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpSer
vletResponse)
java.lang.Object person = null;
^
But if i delete the use Bean Tag, then he says:
org.apache.jasper.JasperException: Cannot find bean person in any scope
What is Tomcat's problem ? I think he don't know what he want !
thanks, Fredy

Betreff: Re: How to iterate over Arraylist
You just have to add at begining of your JSP :
<%@ taglib uri="/WEB-INF/struts-loigc.tld" prefix="logic"%>
Without that, you can see that logic:xx tags appears in resulting HTML not
beeing interpreted by JSP parser.
