Hi,
I have a situation where the user has to select the category of the report from a dynamically generated options in a combo box. Based on the option selected, the options for the second combo box are to be generated.
I have been able to dynamically generarate the options for the first combo box. I however need to capture the option selected here and pass it to the dao in the second combo box to dynamically generate the options. This is where I am not able to progress further.
Any suggestions?
The code is as follows :

<TR><TD WIDTH="30%">Choose Category</TD><TD WIDTH="70%"><html:select        property="categoryOption"  >
                   <%!
                          au.com.dao.ReportCategoriesAvailableFrReqQuery     categoryQuery = new au.com.dao.ReportCategoriesAvailableFrReqQuery();
                          java.util.ArrayList al1 = new java.util.ArrayList();
                          java.util.Iterator iterator1 = null;
                          String category = null;
                          String categorySelected = null;
                    %>
                    <%
                           al1 = categoryQuery.getReportCategory("ROL-ERMLEGAL-USER");                                                      
                           iterator1 = al1.iterator();
                           while( iterator1.hasNext()){
                           category =  ((au.com.beans.CategoryAvailableBean)(iterator1.next()) ).getCategory();                           
                %> 
                        
                         <html:option value="<%=category %>" ></html:option> 
                <%    
                             System.out.println("Category Selected is " + categorySelected );
                           }
