I want to followup to my own message since I finally found a solution to this problem (after many postings with no response) and it might be of interest to the community.
The BeanUtils lib was out-of-date and had fixed a bug around this. Updating that solved the problem. Just a caveat - watch those dependent libraries, the problem may be there and not in Struts or your code. -a -----Original Message----- From: Andy Kriger [mailto:[EMAIL PROTECTED]] Sent: Friday, January 24, 2003 10:26 To: Struts Users Mailing List Subject: how do i use a mapped value in bean:write? I am trying to use mapped values in bean:write but not having any success. * I have a bean named theBean in the session and it defines a method public Item getItem() { ... } * Item defines a method that returns a Map public java.util.Map get Properties() { ... } * The map contains key value pairs e.g. prop1 So, I want to get the value prop1 using bean:write <bean:write name="theBean" property="item.properties(prop1)" scope="session"/> I get a Servlet Exception when I try to load the page java.lang.IllegalArgumentException: object is not an instance of declaring class at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39 ) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl .java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.commons.beanutils.PropertyUtils.getMappedProperty(PropertyUtils.j ava:626) at org.apache.commons.beanutils.PropertyUtils.getMappedProperty(PropertyUtils.j ava:555) at org.apache.commons.beanutils.PropertyUtils.getNestedProperty(PropertyUtils.j ava:747) at org.apache.commons.beanutils.PropertyUtils.getProperty(PropertyUtils.java:78 0) at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:728) at org.apache.struts.taglib.bean.WriteTag.doStartTag(WriteTag.java:290) I've been trying different permutations of single/double quotes around the property name without success.
