<fast4j:list name="PhotoIdAppList" page="<%=pageNo.intValue()%>" pageSize="<%=(session.getAttribute("pageSize") ==null) ? 5 :Integer.parseInt(session.getAttribute("pageSize").toString())%>"/>
I am getting the Exception at thsi point.. Tried to resolve it but coukd not... Its urgent
# 1
try to type cast with (String) rather then using toString().
# 2
type casting can be done as
String
Store the value in any integer variable
Then
String variable = "" + Integer.parseInt(session.getAttribute("pageSize")
<fast4j:list name="PhotoIdAppList" page="<%=pageNo.intValue()%>" pageSize="<%=(session.getAttribute("pageSize") ==null) ? 5 : string variable %>"/>

>(session.getAttribute("pageSize") ==null) ? 5 : Integer.parseInt(session.getAttribute("pageSize").toString())
this can only happen when String you are passing to Integer.parseInt() method does not represent an Integer.
As adviced by my fellow poster i would ask you to go by trying with Type casting the object to a String because, Object.toString() Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
So If Integer.parseInt((String)session.getAttribute("pageSize")) throws
a java.lang.ClassCastException it would be for sure that Object is not representing a String.
And If Integer.parseInt((String)session.getAttribute("pageSize")) throws a Java.lang.NumberFormat Exception then you could be sure that session.getAttribute("pageSize") Object does not hold a Integer Value.
So your next trial tag would be
<fast4j:listname="PhotoIdAppList"page="<%=pageNo.intValue()%>"pageSize="<%=(session.getAttribute("pageSize") ==null) ? 5 : Integer.parseInt((String)session.getAttribute("pageSize"))%>" />
or as adviced by my fellow poster
<%
String Arg = new String("5");
try{
Arg = (String)session.getAttribute("pageSize");
} catch(Exception exp){
log.info(exp.getMessage());
}
log.info("String Cast Succesfull");
Integer PageSize = new Integer("5");
try{
PageSize = Integer.parseInt(Arg);
} catch(Exception exp){
log.info(exp.getMessage());
}
log.info("String has been pared to integer");
%>
<fast4j:listname="PhotoIdAppList"page="<%=pageNo.intValue()%>"pageSize="<%=PageSize%>" />

<fast4j:list name="PhotoIdAppList" page="<%=pageNo.intValue()%>" pageSize="<%=(session.getAttribute("pageSize") ==null) ? 5 : Integer.parseInt(session.getAttribute("pageSize").toString())%>"/>
The problem is probably caused by nested quotes.
Some servers have difficulties determining the proper start/end of the quotes when nested within custom tags.
As a solution try using single quotes to delimit the attribute values, and double quotes to delimit the strings within the expressions:
<fast4j:list name='PhotoIdAppList' page='<%=pageNo.intValue()%>' pageSize='<%=(session.getAttribute("pageSize") ==null) ? 5 : Integer.parseInt(session.getAttribute("pageSize").toString())%>'/>
