RE: get the selected values from list box

Is a List box an HTML <select> that allows multiple selections?

What does the corresponding Form bean property look like?  I don't have any
multiple select lists, but I think you use String[] for the get/set methods
in the Form bean, and Struts will populate it from the Request.  Take a look
at the struts-example webapp, it probably has an example of this.

This part is not really Struts-specific.  You need to have already figured
out your data access layer before you add Struts to the mix.  And you
haven't told us what database, whether it has a JDBC driver, etc., so it's
pretty hard to advise.  While you _can_ put JDBC code directly in your
delete Action, resist the temptation!  Unless this is a small one-time
project purely for demonstration purposes, do it right the first time, or
else you'll be back doing it over later.  (BTDT... ;)

RE: get the selected values from list box

[dream weaver <dr...@yahoo.com>]

Hi Wendy, Thanks for the advise, but I still not able
to make it work. Could you please give me more help? 

Yes it has a JDBC driver. I want the list box to make
multiple selections. First how I can get the multiple
selected values (User selected) to my action file for
processing? the following is on my JSP file:

<logic:iterate id="tool" name="listTools"
scope="request">

<option value="<bean:write name="tool"
property="poNbr"/>
<bean:write name="tool" property="ToolNbr"/>
<bean:write name="tool" property="ToolUnit"/>
<bean:write name="tool" property="history"/>
<bean:write name="tool" property="toolId"/>">

<bean:write name="tool" property="poNbr"/> 
<bean:write name="tool" property="ToolNbr"/>
<bean:write name="tool" property="history"/>
</option>
</logic:iterate>
