Oh ok... now this is a little time travel for me. Have not used Struts 1 in the past 5 years (thanks heaven). Do you know this tag? http://struts.apache.org/1.x/struts-taglib/tagreference.html#html:options You'll need that and make a bean accessible for this tag. here is a short example which might help you: http://www.vaannila.com/struts/struts-example/struts-html-select-tag-example-1.html Cheers Christian > > > On 9/28/2011 12:14 PM, Christian Grobmeier wrote: >> >> Ajib, >> >> I am using jQuery, which makes an json object out of the json string >> you would get.
