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.

* *@(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.

* *@(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

Hi,



I am migrating an existing application from struts 1 to struts 2. It uses
MessageResources. I found out that the replacement for the same in struts2
(2.0.11)is WrapperMessageResources which extends from the MessageResources.
But to use the WrapperMessageRessource I need to use the struts
1.3.5-core.jar provided along with the struts 2.0.11 release otherwise I get
a compilation error as "MessageResources class not found. It is used
indirectly by one of the class files". So is it proper to use the struts
1.3.5-core.jar? If not Pls suggest a replacement for MessageResources.



Thanks,

Sandeep

Err... sorry Sandeep but I think that you are following a wrong approach.
If you want to convert an application from Struts 1 to Struts 2 you need to
learn Struts 2 almost from scratch. Don't think in "replacements", since
Struts 1 and 2 are two different things.

Hello

I am using struts 1 to show a link to the user like this
<html:link
            page="/editProjectMonitor.do" paramId="report_id"
paramName="report"
            paramProperty="reportId" target="_blank">
          Edit</html:link>

However I want this link to open up from Javascript instead! For javascript
I have a code like the following

function openPopup() {
windowReference = window.open('/cmrs/editProjectMonitor.do?report_id=<%=WHAT
TO PUT HERE? SO I CAN GETT report_id value%>','windowName');
if (!windowReference.opener)
windowReference.opener = self;
}

what can i pass so that report_id value will come. I know in struts2 I could
have used the s:property tag...is there something similar in struts1?

Thanks!!

Mmm... ready for a "do your own homework" answer?

When i extend the Action class to implement the db/business logic



Bad habit, the db/business logic should be elsewhere, not in actions...

is it

If you don't know it, then probably you don't know Struts 1: I feel that you
wanted to fool your interviewer, right?

Sorry for the rant.

         <action name="Dojo">

             <result>/pages/test4Dialog.jsp</result>

         </action>

 

   When I try to access this page with URL(http://localhost:7001/hibernate/events/Dojo.action), I'm getting below error message in firefox console.

 

dojo is not defined

  dojo.require("dojo.parser");

 

I didn't place any dojo plugin jar files in my library? I think struts2 is supporting Dojo inclusively.

 

If I need to install Dojo plugin to correct this problem then where I can find this .jar file(dojo plugin)?

 

  Please let me know, how to correct this problem. 

 

Have a nice day.

 

Thanks,

Sharath.
