Hi GURUs:
I am doing a drop down box with Struts, and I have seen previous post on the forum regarding how to do that.

Basically I have 2 classes
InquiryAction and InquiryResult.jsp

here is the code snippet from InquriyAction

and here is where I do the population of the drop down box in my JSP code

However when i test the JSP page on my local app server, i got the following error:

javax.servlet.jsp.JspException: Cannot find bean under name org.apache.struts.taglib.html.BEAN
at org.apache.struts.taglib.html.SelectTag.calculateMatchValues(SelectTag.java:301)
at org.apache.struts.taglib.html.SelectTag.doStartTag(SelectTag.java:244)
at jsp_servlet.__inquiryresults._jspService(__inquiryresults.java:544)

I did bind the "inquiryResults" with an arrayList, can somebody tell me what is wrong? thanks...

Well, for starters, you can't place that bean tag in your html tag.
Try:

<logic:iterate id='transaction' collection='<%= request.getAttribute("inquiryResults") %>'>
<% String prKey = ((TransactionBean)transaction).getPRKey(); %>

<html:option value='<%= prKey %>' >
<bean:write name='transaction' property='PRKey'/> (or reuse <%= prKey %>)
</html:option>
</logic:iterate>
</html:select>

or u could simply use <html

ptions> tag as follows:

<html:select property="selectedValue"> <html

ptions collection="inquiryList" property="idValue" labelProperty="displayValue"/> </html:select>

hope this helps,
