I am trying to iterate over a linked list but have not got it to work. Compile error on the 'For' line.

My code:

List temp = new LinkedList(); loop... temp.add(new IndentedBillV8(item, levelCounter, "1")); endLoop… for(IndentedBillV8 indentedBillV8: temp){ }

I have the following code which produces the following:

875987-405
875987-405
875987-405
875987-405
875987-405
875987-405
875987-405
875987-406
875987-406
875987-406
875987-406
875987-406
875987-406
875987-406
875987-406
875987-406
875987-406

String partnoList = ""; int partnumbercount = 0; if(transportStagingPickItemDetailList != null){ if(transportStagingPickItemDetailList.getTransportstagingpickitemsdetaillist() != null){ for(TransportStagingPickItemDetail transportStagingPickItemDetail: transportStagingPickItemDetailList.getTransportstagingpickitemsdetaillist()){ if(transportStagingPickItemDetail.getCono().equals(cono) && transportStagingPickItemDetail.getGroupno() == groupno){ partnoList = partnoList + transportStagingPickItemDetail.getPartno() + "\r\n"; partnumbercount ++; } } } }

What I need is this:

875987-405 7 Ea
875987-406 10 Ea

Found this and is seems to work. Thanks for heading me in the right direction.

value="${fn:escapeXml(text)}">

This is the browser dom out put when viewing with the Dev Tools.

It looks like the double quote is being separated from the rest of the value.

<option value="IV3-1/4" "="">IV3-1/4" ENSOLITE</option>

I have a select list with an option value of IV3-1/4"

But this code returns IV3-1/4

$('.samplinginspectionitemnolist').on("change", function(){ alert($(this).val()); });

Edited to fix code typo

This would solve my challenge but we are not using Java 8 yet. Thanks.

Yes, you have correctly interrupted my challenge. I will try your previous solution. Thanks.

This is an example of one of my strings:

SEAT AY-AAR CTR IAT IVS TPL

This is what I would like my result to be:

CTR IAT IVS TPL

My code:

public final static String QMS_ALLOWED_CHARS_CSS_DESC = "[^(L/H|R/H|IAT|CTR|IVS|TPL)\040]"; myString.trim().replaceAll(GenericPrams.QMS_ALLOWED_CHARS_CSS_DESC, "");

Results I am getting:
SAT AAAR CTR IAT IVS TPL

But if I open 3 Edge windows, they'll all be using the same cookie pool, so all of the windows will be talking to the same session. If one window logs off, the sessionid is now invalid for all 3 windows.

This is my situation. What if any is the best way to deal with this?

Tim Moores wrote:By "instance" I assume you mean "browser window connected to the same web app". It sounds as if you're talking about sessions being invalidated. Why do you need separate session for the same user?

Yes I am talking about sessions, and I do not need separate sessions for same user.

Normal application behavior:
In my web application I have set up certain criteria for invalidation.
….

Now from the users perspective:
I open an instance of the web app - all is good.
For some reason I decide to open a second instance of the same app - again all is good, at least for a bit.
Now thru my normal app process the first instance invalidates.
Oh no, since both instances share the same session handle the second instance invalidates also.

May be wrong forum. If so sorry.

In my web application I have set up certain criteria for invalidation.

If a user opens two instances of the same application on the same machine once the first instance invalidates
the second instance invalidates also.

Is there a way to handle this?

I would like to limit the user to one instance but from what I read that is discouraged.

Articles I read said the response may already be configured and the setting not incorporated if not do this way.

Can you answer another question for me? If I am checking for session = null how do I still get an IllegalStateException on the line session.invalidate()?

if(session != null){ if(session.getAttribute("userDataObj") != null){ User user = (User)session.getAttribute("userDataObj"); QMSConfigurationParms qmsConfigurationParms = (QMSConfigurationParms)session.getAttribute("QMSConfigParmsObj"); DefaultPrams dft = (DefaultPrams)session.getAttribute("defaultpramsObj");        new FileCleanUp(user, qmsConfigurationParms, dft); } RequestDispatcher disp = session.getServletContext().getRequestDispatcher("/Layout/Layout-Misc/TimedOutDisplayForm.jsp"); disp.forward(request, response); session.invalidate(); // Invalidate manuall }

Tim Holloway wrote:First you need to find out why all those sessions are alive at the same time. Do you have actually that many online users? If so, they may be legitimate and the only real choices are A) IBM (Install Bigger Memory), B) reduce the amount of session data being used by the offending application(s), C) Change the apps to minimize their use of an HttpSession environment (if you're using container security, that basically means making pages that don't really need the user to be logged in be unsecured - or Just In Time Login, if you prefer. D) Run a cluster. E) Convert to ReST (which is item B carried to its logical conclusion).

And F) Are these active users, or should you shorten the session timeout to drop people who left the site without logging off?

You might want to add Session Listeners to log the start and stop times (and thus durations) of the sessions, and at destroy time, look at how many/how big the collection of session-scope variables hanging onto it is.

A couple of things I have done is increase the Heap Size to 7G. I am working on code to invalidate the session if idle for a specified time.
I am using Session Listener also.
So the invalidate fires either automatically(inactivity), when the user logs off(does not shut the application down), and when the page is actually closed.

However, when either of the first two fire do I just loop back to the initial application start up?

I am wanting to move some repetitive code into my filter.

In every doPost method of each Servlet I have:

response.setHeader( "Pragma", "no-cache" ); response.setHeader( "Cache-Control", "no-cache" ); response.setDateHeader( "Expires", 0 ); response.setCharacterEncoding("UTF-8");

Here is a part of my Filter code to do this. I just want to know it this is the correct way:

private static class SessionAccessAwareResponse extends HttpServletResponseWrapper { public SessionAccessAwareResponse(HttpServletResponse response) { super(response); response.setHeader( "Pragma", "no-cache" ); response.setHeader( "Cache-Control", "no-cache" ); response.setDateHeader( "Expires", 0 ); response.setCharacterEncoding("UTF-8");        } }
