Thanx Laurie Harper,
I am using jprofiler to monitor instances.
you are right that it may be possible that my action classes might be
referencing
to any long lived objects and that prevents it from being garbage collected.
yeah, for some action classes spring inject singleton scoped service
dependecies so that might be reason for those action for not getting garbage
collected
but i have one action class which doesn't have any thing which can prevent
that class from
being garbage collected.
its as given below:
*
public* *class* AuctionCentralAction *extends* ActionSupport{
/**
*
*/
*private* *static* *final* *long* *serialVersionUID* = 1L;
*private* String catalogList;
*private* String previousCatalog;
*private* String previousCatalogList;
/**
* This method is called while loading the Auction central page.
* [EMAIL PROTECTED]
*
*/
*public* String initialize() {
*this*.catalogList="Auction";
*this*.previousCatalogList = "Auction";
*this*.previousCatalog = "0";
*return* "auctionCentralAction";
}
/**
* This method is for validating the user going prior to the My personal
Account page.
* If user is valid then he will take to My personal Account page otherwise
same page will
* be displayed.
* [EMAIL PROTECTED]
*
*/
*public* String viewPersonalAccountInfo()
{
String returnString;
UserContext user = ContextProviderRegistry.*getInstance*
().getContext().getUserContext();
String userRole = user.getUserRole();
*if*(userRole.equalsIgnoreCase("ROLE_USER") == *true*){
returnString = "viewPersonalInfo";
}*else*{
returnString = "auctionCentralAction";
}
*return* returnString;
}
*public* String getCatalogList() {
*return* catalogList;
}
*public* *void* setCatalogList(String catalogList) {
*this*.catalogList = catalogList;
}
*public* String getPreviousCatalog() {
*return* previousCatalog;
}
*public* *void* setPreviousCatalog(String previousCatalog) {
*this*.previousCatalog = previousCatalog;
}
*public* String getPreviousCatalogList() {
*return* previousCatalogList;
}
*public* *void* setPreviousCatalogList(String previousCatalogList) {
*this*.previousCatalogList = previousCatalogList;
}
}
In my case ,initialize() method will be executed, can anybody tell me
what's there in
the above class which can prevent this class from being garbage collected.
static data member or what?
thanx in advance,
Manish
