Bean tag lib help
Hello,
I got a question. My struts-bean tag doesnot seem to work correctly.
Everytime I use the Bean tag
Eg
I get a
java.lang.ClassCastException
at org.apache.struts.taglib.html.FormTag.lookup(FormTag.java:766)
at
org.apache.struts.taglib.html.FormTag.doStartTag(FormTag.java:481)
at org.apache.jsp.files_jsp._jspService(files_jsp.java:149)
The Java code looks like
_jspx_th_html_form_0.setParent(_jspx_th_html_html_0);
_jspx_th_html_form_0.setMethod("POST");
_jspx_th_html_form_0.setAction("/files");
149-> int _jspx_eval_html_form_0 = _jspx_th_html_form_0.doStartTag();
if (_jspx_eval_html_form_0 !=
javax.servlet.jsp.tagext.Tag.SKIP_BODY) {
do {
out.write("\r\n ");
/* bean:define */
java.lang.Object processName = null;
org.apache.struts.taglib.bean.DefineTag _jspx_th_bean_define_0
= (org.apache.struts.taglib.bean.DefineTag)
_jspx_tagPool_bean_define_property_name_id.get(org.apache.struts.taglib.bean
.DefineTag.class);
Doea anyone have any ideas how to fix it

RE: How to return to form element
Hms sounds nifty but how would I then display an error message as
well
The more I use JS the more I like it

RE: Bean tag help
Hm
Why do I need a bean name and type in struts-conifg.
The JSP I'm running is a basic page all it does is user the bean tag eg:
<%@ page language="java" import="java.net.URLEncoder"
contentType="text/html;charset=utf-8" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/controls.tld" prefix="controls" %>
body bgcolor="white" background="/images/PaperTexture.gif">
It always dies on the first bean saying it had a ClassCastEsception when
trying to locate the Start tag
I'm not clear asd to why you need to use a bean name and type??
Examples would be good

RE: Bean tag help
Huh Sorry but you've lost me completely ... Maybe I should have explained that I've never programmed struts before and that I've been assigned to fix up the work of a person who has left the project, and while I've understood, overcome and finished most of the concepts and problems this particular one completely stumps me.
