The "." operator was supplied with an index value of type "java.lang.String" to be applied to a List or array, but that value cannot be converted to an integer

      }

empObjectDao.getAllMyObjectVOs(1) return Object ;in that object myObjectModel.Results returns List ;

Hi,

As you yourself said that the return from myObjectModel.Results is a List. Is it a List of Beans??? Or just a plain List.

I believe, the returned List is a plain List and NOT the list of beans. In that case, mobj.id will not be able to identify "id".

should be
>In that case, mobj.id will not be able to identify "id", "name", "address"..etc

<c:forEach items="${myObjectModel.Results}" var="mobj" varStatus="status">
<tr>
<td> <a href='MyObjectForm.html?id=<c:out value="${mobj.id}"/>' ><c:out value="${mobj.id}"/></a> </td>
<td> <c:out value="${mobj.name}" /></td>
<td> <c:out value="${mobj.address}"/></td>
<td> <c:out value="${mobj.email}"/></td>
<td> <c:out value="${mobj.phone}"/></td>
</tr>
</c:forEach>

try this out , it will most probably work.

i already tried its not working

Kuldeepchaturvedi

just to check what mobj is returning,
print it on the page..

<c:forEach items="${myObjectModel.Results}" var="mobj" varStatus="status">
<td> <c:out value="${mobj}" /></td>
</c:forEach>

I think Fargo is correct in his assumption that the list being returned is not of beans...

dataBaseList is the List of beans;dataBaseList is added into mainList(this is another arraylist) and it is assigned it to searchModel.searchResults;

public SearchModel getAllMyObjectVOs(SearchModel searchModel) {

                  while (maxRows > i++) {
                        dataBaseList.add((Employee)scr.get(0));

                        }

                               mainList.add(dataBaseList);
                               searchModel.totalRecords= l.size();
                               searchModel.searchResults = mainList;

return searchModel;

            }

Hi,

So it means you have list of list. It definitely means you have to change the handling in JSTL tags. OR in the first place why do u need to add it in another list ?

in dataBaseList i have only Employee objects and also i need totalrecords and pagenumber that is not there in employee object so i have taken another object i.e searchModel

fargo

Hi,

May be making a copy is better for you and you need not to change the jstl handling

public SearchModel getAllMyObjectVOs(SearchModel searchModel) {

while (maxRows > i++) {
dataBaseList.add((Employee)scr.get(0));

}

Object[] contents = dataBaseList.toArray();
Object[] newArray = new Object[contents.length];
System.arraycopy(contents, 0, newArray, 0, contents.length);

searchModel.totalRecords= l.size();
searchModel.searchResults = Arrays.asList(newArray);

return searchModel;

}
