<logic:iterate name="ProjectListForm" id="abcd" property='<%= "projectListValue["+ctr+"].validStatus" %>'  >
<bean:write name="abcd" />
</logic:itwerate>

it is print like " a b c d" .


Now i want to print he same result in drop down  (listbox) like one by one.


<html:select name="ProjectListForm" property='<%= "projectListValue["+ctr+"].validStatus" %>'     styleClass="projectdetaillist"  disabled = "false" >
<html:options name="ProjectListForm" property='<bean:write name="abcd">' /> 
</html:select>

Do you mean validStatus is an array of the Strings "a", "b", "c" and 
"d", or a string array with one entry "a,b,c,d"? I'll assume you mean 
that you used a StringTokenizer to create the 4-element array from the 
simple string "a,b,c,d".

I'm not sure what the projectListValue["+ctr+"] bit is about, but I'll 
assume your form bean has an indexed property 'projectListValue and that 
the individual elements of that indexed property are beans with a 
validStatus property, which is of type String[].

There are several things wrong here. First and foremost, you can't nest 
JSP tags that way (i.e. you can't use a JSP tag to set the value of an 
attribute on another JSP tag).

Secondly, the bean:write tag is referencing the scripting variable 
'abcd', which you're not defining in this case.

Thirdly, you've set the html:select tag's 'property' attribute to point 
to a property which (based on the above) is a String array, but you 
haven't included multiple="true". Unless you want a multi-select, you 
should be pointing to a String property rather than a String array 
property here.

I *think* what you're trying to do is something like this:

   <html:select property="currentSelection">
     <html:options
       property='<%="projectListValue["+ctr+"].validStatus"%>'/>
   </html:select>

(Note that you don't need to explicitly specify the form with the 'name' 
attribute, the html:* tags will automatically use the form bean 
associated with the enclosing html:form tag).
