hi all
i have a doubt over connection pooling.When 5 users are using a project in
struts and if i have defined the maximumnumber of connection to 4 .Then how
many connection will be estblished.What i mean to say is how many visible
connection will be there in mysqlprocess

Subject: Multiple nested Hashmaps. Limit?
I am running into a problem with multiple Mapped nested properties
When I use the following lines to access the Value form my dynaValueObj
Object I get this error
<%
String
value="dynaTableObj.dynaRowObjs("+rowNm+").dynaValueObjs("+key+").dynaCo
lumnValue";
%>
<html:text name="DynaTableDataForm" property="<%=rowNmdd%>" size="20"/>
[ServletException in:/WEB-INF/src/jsp/dyna/dynaTableData.jsp] Null
property value for 'dynaValueObjs(1)''
After tracing I found that it is not calling getDynaValueObjs(String xx)
but calling getDynaValueObjs().
Is there a limitation on how many map-backed properties you can
reference?
Thanks
