[L Willie]

    
			HashMap linkDetailMap = new HashMap();
			try{
				AttrRowLineXrefDetail arlxd = (AttrRowLineXrefDetail)linkMap.get(id+"-"+itemNo);
				if(arlxd!=null && arlxd.size()>0){
                                       for(int i=0; i<arlxd.size();i++){
					someFormRow afr = new SomeFormRow();
					
					
					afr.setItemNo(arlxd.getItemNo());
					afr.setRowSetting(arlxd.getRowSetting());
					afr.setQty(arlxd.getQty()+"");
					
					
					linkDetailMap.put(arlxd.getItemNo()+"",afr);
                                        }

First, using Java in JSPs is not a good practice. JSPs meant to be the view part of the application. Of course you can write Java inside JSPs (inside a scriptlet <% ..... %>) but as I said it's not done these days. You may use a combination of JSTL, EL, Custom tags and Standard actions to achieve the same. Checkout the JspFaq for more about those.

Get the JSTL set up as Vijitha Kumara correctly suggested, and use the <c:forEach> tag to iterate over the Map. Be aware that for each iteration, the iteration item will be an instance of Map.Entry.
