Access a value in HashMap where key is an object and value is a collection of VO

[amarshi mohanty]

Hi All,

I have the below code in a action class .

    
while(ir.hasNext()){
String trackId = ir.next().toString();
Collection listValues1 = wfmsWorker.getValidationMainPageValues(wfmsId,sortTypeForm, sortDirectionForm, offsetValue, flag, trackId);
hm.put(trackId,listValues1);
}
session.setAttribute("hashMapItems",hm);

The listValues has collection of VO's .
How to access the value in jsp using EL?

${hashMapItems.key}

if i iterate the hm like :

    
Iterator hIter = hm.entrySet().iterator();
	while(hIter.hasNext()){
	String value = hIter.next().toString();
	log.info("value = " +value);
}

m getting:

value = 20100128-2=[class se.ralip.openarchive.vo.WfmsInvoiceManagementVO[ supplier=Mohanty: documentId=54318: invioceNumber= 3386675205: invoiceDate=19/12/2008: dueDate=19/12/2009: amount=400.00: arrivalDate=null: status=archived: scanno=123_457 ], class se.ralip.openarchive.vo.WfmsInvoiceManagementVO[ supplier=Mohanty: documentId=54319: invioceNumber= 3386675205: invoiceDate=19/12/2008: dueDate=19/12/2009: amount=400.00: arrivalDate=null: status=archived: scanno=123_458 ], class se.ralip.openarchive.vo.WfmsInvoiceManagementVO[ supplier=Mohanty: documentId=54320: invioceNumber= 3386675205: invoiceDate=17/12/2008: dueDate=18/12/2009: amount=4010.00: arrivalDate=null: status=archived: scanno=123_459 ]]


so how can i giv the {hashMapItems.key.supplier}
do i need [] operator for this?

Sorry, the jumble you posted makes no sense to me.

If you want to access a member of the map by key, use the syntax I already posted. If what's returned by that is a bean (or another map) you can keep going. For example:

${myMap.person.address.city}    

This assumes that the keys are valid identifiers. If the keys are not identifiers, you need to use the [] notation.
