Hello!
I had the same problem...
You have to include the <html:select> tag into <html:form> tags. Look:
<html:form action="/language" method = "GET" >
<html:select property="language" onchange="javascript: submit ()">
<html:option value="Deutsch"/> <html:option value="Englisch"/>
</html:select>
</html:form>
I have an ActionBean and a FormBean for the action "/language".
Without that you will get the exception
"Cannot find bean under name org.apache.struts.taglib.html.BEAN"
Hope, that will help!
Dirk

Betreff: Error Using select tag To Create Drop-Down Menu
I am doing testings step by step. I simply want to add
a drop-down menu feature to something that works OKay.
I am a newbie to struts. I do not know where to look
for my mistakes when I encounter problems.
Something is wrong in my .jsp page. This .jsp page had
worked fine before <html:select>...</html:select>
tags were added. The error message is:
code:
------------------------------------------------------
2003-07-21 01:24:51
StandardWrapperValve[action]:Servlet.service() for
servlet action threw
exceptionorg.apache.jasper.JasperException: Cannot
find bean under name
org.apache.struts.taglib.html.BEAN
-------------------------------------------------------
Here is the source code of my MainMenu.jsp:
code:
-------------------------------------------------------
<%@ taglib uri="/WEB-INF/struts-html.tld"
prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld"
prefix="bean" %>
<jsp:useBean id="LogonBean" scope="request"
class="resources.version1.LogonBean" /> <HTML> <HEAD>
<TITLE><bean:message key="title.mainmenu" /> </TITLE> </HEAD> <BODY>
<bean:message key="heading.mainmenu" /> <p>
<bean:message key="label.userType" />:
<b><jsp:getProperty name="LogonBean"
property="userType" /></b>
<br>
<B>State: </B>
<html:select property="state">
<html:options collection="STATES"
property="value"
labelProperty="label" />
</html:select>
</BODY>
</HTML>
-------------------------------------------------------
In the LogonBean.java, I inserted in the
setParameters(....) method the following code:
code:
-------------------------------------------------------
public void setParameters( HttpServletRequest request
){ userID = request.getParameter("userID");
password = request.getParameter("password");
ArrayList states = new ArrayList(); states.add(new
LabelValueBean("Virginia", "VA")); states.add(new
LabelValueBean("Maryland", "MD")); states.add(new
LabelValueBean("Ohio", "OH")); states.add(new
LabelValueBean("Rode Island", "RI")); states.add(new
LabelValueBean("New York", "NY"));
request.setAttribute("STATES", states);}
------------------------------------------------------
I would appreciate if anybody could point out my
mistakes.
