problem in logic:iterate using HashMap
Hi, I tried the same mentioned by Rick. But it gives me the following error. java.lang.NullPointerException at java.util.Hashtable.get(Hashtable.java:329) at org.apache.jasper.runtime.PageContextImpl.findAttribute(PageContextImpl.java :308) My code goes like this Here "useradmins" is HashMap in a formbean (I haven't specified name="formbeanName" [because it is Not mandatory]). Surprisingly the error is for Hashtable!!!

Re: logic:iterate using HashMap
O_Parthasarathy Kesavaraj írta: How to iterate thro HashMap using logic:iterate? You did not look into the docs, did you? http://jakarta.apache.org/struts/userGuide/struts-logic.html#iterate Normally, each object exposed by the iterate tag is an element of the underlying collection you are iterating over. However, if you iterate over a |Map|, the exposed object is of type |Map.Entry| that has two properties: * |key| - The key under which this item is stored in the underlying Map. * |value| - The value that corresponds to this key.
