you use .key or .value, e.g

item.value['key']
item.key

 Subject: Easy EL question
 
 
   Hello !
 
   I'm still having problem with all the different syntax used in
 JSP... so excuse my question if it sound really stupid !
 
   I'm having to iterate on the values of a Map. So I'd like
 something like that :
 
 c:catch
   c:set var=items value=${itemsMap.values}/
 /c:catch
 
 c:forEach items=${items} var=item
   [do something]
 /c:forEach
 
   Of course, it doesnt work because there is no getter in a Map to
 get the values ...  There is probably a very easy and standard way to
 do exactly that ... could you help me on that one ?
 
   Thanks
 
 
  Guillaume

Re: Easy EL question

  Thanks for your answer !  But I'm afraid I dont really understand
how to use it ...  Do you mean I should iterate on the keys of my Map
? But then the question is of course How do I iterate on the keys ?.

  Maybe I should be more precise in my example, so here is my actual
code (which doesnt work).

dmaAssistantSession.deletedDmasSimple is a Map of beans (id, label).
The key to the Map is the id of the bean itself (but I dont use the
key here).

c:catch
  c:set var=deletedDmas value=${dmaAssistantSession.deletedDmasSimple}/
/c:catch

   ul id=overviewDeletedDmas
  c:forEach items=${deletedDmas} var=deletedDma
li
  html:link action=/DMAAssistant/ChooseDeletedDMAToCancelRemove
paramId=id paramName=deletedDma paramProperty=id
bean:message name=deletedDma property=label/
  /html:link
/li
  /c:forEach
/ul

  Thanks a lot for the answer, but I would be even more thankfull if a
bit more explanation goes with it ...

Hi,

With what you supplied, the answer was the best you could have expected. The 
deletedDma item per loop iteration is of type MapEntry. This has getKey and 
getValue, hence why you can call deletedDma.key and deletedDma.value. 

In html your link would be

a 
href=/DMAAssistant/ChooseDeletedDMAToCancelRemove?id=${deletedDma.value.id}Remove/a

I am not sure if you can pass this into the html:link tag.

Try ...

// you don't need this block by the way
c:catch
  c:set var=deletedDmas 
value=${dmaAssistantSession.deletedDmasSimple}/
/c:catch


ul id=overviewDeletedDmas
  c:forEach items=${dmaAssistantSession.deletedDmasSimple} var=deletedDma

li
  html:link 
action=/DMAAssistant/ChooseDeletedDMAToCancelRemove
 paramId=id paramName=deletedDma.value paramProperty=id
 bean:message name=deletedDma.value property=label /
  /html:link
/li
  /c:forEach
/ul

Thanks a lot for the clarification (and for the short time between
question and answer, amazing !). I know, my question was probably not
clear enough, but ... I'm so uncomftable with JSP for the moment that
I dont really know how to ask the questions ...

  I finally resolved it with : 
c:forEach items=${deletedDmas} var=deletedDma
  html:link action=/DMAAssistant/ChooseDeletedDMAToCancelRemove
paramId=id paramName=deletedDma paramProperty=value.id
bean:message name=deletedDma property=value.label/
  /html:link
/c:forEach

  It might be of some help if somebody has the same problem as me one
of this day ...

 // you don't need this block by the way
// I know, it just help type a bit less when reusing the var ...
 c:catch
   c:set var=deletedDmas
 value=${dmaAssistantSession.deletedDmasSimple}/
 /c:catch


  Again, thanks a lot for your great help ! I think I'm slowly getting
into JSP ...
