RE: logic:iterator Class cast exception

[Claudio Parnenzini]

Sorry for late answer I was sick for a couple of days.

Yes, I have imported in my JSP page all relevant classes.

Since the error is a JSP compilation error, it's not related to the code
in
your action. Are you importing all the relevant classes at the top of
your
JSP page?

Subject: logic:iterator Class cast exception


Hi all,

I'm trying to iterate a Vector into a JSP page and I have an Class cast
exception. My vector contains an Hashtable that contains String object.

Here my ActionBean code for the iteration:


      while(rs.next()) {
        Hashtable table = new Hashtable();

table.put(SQLConstants.FieldName.BSP.BSP_ID,rs.getString(SQLConstants.Fi
eldName.BSP.BSP_ID));

table.put(SQLConstants.FieldName.BSP.BSP_FULLNAME,rs.getString(SQLConsta
nts.FieldName.BSP.BSP_FULLNAME));
        vectorBsp.add(table);
request.getSession().setAttribute(Constants.BSP_LIST,loadBsp(errors));
      }

Into my jsp, I iterate in this way.

       <logic:iterate id="<%=Constants.BSP_LIST%>" name="bspList">
        <tr class="TableValue">
                <td><%=
(String)((java.util.Hashtable)bspList).get(SQLConstants.FieldName.BSP.BS
P_ID)%>
                <td><%=
(String)((java.util.Hashtable)bspList).get(SQLConstants.FieldName.BSP.BS
P_FULLNAME)%>
        </tr>
        </logic:iterate>


Here the error message.
