Reloading of Dynamic Tiles

I am new to Struts and Tiles framework in Struts. As the header and footer are same for all the JSP pages, will the header and footer tiles be reloaded each time a left navigatin link is clicked. Is there a method that we can have them load only once(for the first time).

I have not really tested in in V6.1 but in V6.0 it was possible to add the line into web-apps.xml file with the following:
<class-loader reload-interval="XX"/>
where XX is seconds between reloads. i.e. 3600 to reload every hour.
In V6.1 that setting is in server.xml
and is called "dynamicreloadinterval". You can try playing with it. But as I said I have not really tested how that works...

ADF:Dynamic Region Refreshing

Hi,
My JDeveloper version is 11.1.1.5
I am facing one problem.
I have one table to which I have Save and Remove buttons.
To the Save button, I have one action which programmatically inserts the row into the table. And Remove button removes the row present from the table programmatically.
The Problem I am facing is, whenever I save or remove I need to reload the page to see the row inserted or deleted. It is not happening automatically...
Could anyone please tell me how to reload a dynamic region which reflects DB table modification onto the Dynamic Region?
Many thanks in advance

Hi Guys,
Here I will try to put my scenario...
There is one table called APPLICATION which displays all the data using ViewObject1. To this table I am adding and saving and deleting a new row.
ViewObject1 Query :
SELECT Application.BUSINESS_UNIT,
Application.DESCRIPTION,
Application.ID,
Application.NAME
FROM APPLICATION Application
And there is one more viewObject which refers the same table which also displays the same columns with the data which is mentioned in below viewobject query.
ViewObject2 Query:
SELECT Application.BUSINESS_UNIT,
Application.DESCRIPTION,
Application.ID,
Application.NAME
FROM APPLICATION Application
WHERE ID not in (select ID_application from project_application)
So
Whenever I am saving/removing a row, the table with ViewObject1 is being reflected with the saved row... but not the table with ViewObject2. So can you please advise me how to reflect the saved row in ViewObject2 also..
ViewObject1 and ViewObject2 are referring to the same table(APPLICATION) in the DB with different queries...
Many Thanks in Advance,

Dynamic Linking Doesn't Renew

I use AME exstensively, normally no issues (lot's of FLash, MPEGs, WMV from various sources).
There is one little thing that seems to crop up when I'm using a dynamic link from AE or PrP.
Once a sequence of comp is linked and I make a change in the original file and then go back to AME the old file content is cached abnd doesn't change. I can remove the file from the queue and replace it but the old content is still there.
If I shut down AME and then reload the link again in the new istance, the new file content is there.
AM I missing something here? Or is there a caching bug bitting me.

Jim:
Thanks for the thoughts. I understand your answer and we're missing the mark here. Let me explain:
Step one: Load a sequence or comp in a dynamic link.
Step two: Discover an error. Stop rendering (Let's say a misspelled title).
Step Three: Go back to AE or PrP and make correction.
Step Four: Go back to AME and reload , not duplicate, the repaired file. However the repaired file is not what reloads. You will get the same earlier version that need the fix. So,
Step Five: Close AME, reopen and load the file in question again. This will show the fresh file and rending can begin again.
I understand reloading the repaired file, but I shouldn't have to shut down AME to reload a dynamically linked file.
If I am in AE or Premiere or even Encore, and I change an outside file such as a PSD or other file, the version loads on refresh (or sooner) as it should be.
I'm running a 64 bit platform here with Cuda graphics, and plenty of memory on a machine that only has Creative suite installed, nothing else.
Back to you

Dminiwm snapwm & bipolarbar

As a consequence of the catwm thread and the thread about my port of catwm to xcb we have this thread about a dynamic tiling window manager with no major bugs!
I saw gold in catwms' save_desktop function.
It's simple; there's no floating windows, no status bar, popups are treated like any other window etc.
There's choice in the tiling method; new window is master or attach aside.
There's choice in the tiling mode used; Vertical, Horizontal, Fullscreen, Stacking and Grid.
You can even resize the window at the top of the stack
Changing a tiling mode or window size on one desktop doesn't effect other desktops.
Most changes can be made in the config.h file:
Like if you want space to run a panel
Whether to focus the window the mouse just moved to
Whether to follow a window when you send it to another desktop
What application to open on what desktop
Colours, keyboard shortcuts etc, etc
It's light on resources both in filesize and memory used.
I paid for the whole screen and I'm going to use the whole screen so dynamic is the way to go.
If you want to try a light dynamic tiler it's on github.
Cheers
Update:
There's been lots of little bugs fixed and a few enhancements along the way. The biggest additions are a bar, which has a clickable desktop switcher, shows the tiling mode and focused windows' name and has space to show external text like conky, and there's a reloadable rc file. Since dminiwm is about staying under 1000 sloc the wm with the bar goes by a different name - snapwm
Here's a pic of snapwm in action:
So this thread is now about two window managers, dminiwm and snapwm, which have the same window manager functions. The only difference between them is snapwm is dminiwm with the reloadable rc file and the bar.
Thanks to stlarch snapwm has a wiki page here.
Update2:
There's now a multi monitor version of dminiwm, that's still under 1000 loc.
Update3:
After some good practise with some_sorta_bar I made bipolarbar(formerly splitter_bar), which is a lightweight bar for window managers that takes two inputs with different timings. It is aimed at, but not limited to, monsterwm users. Here is the first announcement of it or see the Readme on github for usage clues.
Here's a pic of it in action with dminiwm:
Update4:
There's now a stable release of snapwm.

Approve Request App on Fiori Wave2 - Error

Hi,
We are trying to use the Approve Request App on Fiori Wave2.A dynamic tile has been created. While trying to launch the app from the Approver id we get a popup saying Failure-Unable to launch App. Steps mentioned in the Approve Request app on SCN (links referred : http://scn.sap.com/docs/DOC-46215 and http://help.sap.com/fiori_bs2013/helpdata/en/a8/995952d9a6617fe10000000a44538d/content.htm have been followed and checked.
Could you help us with this issue?
Attached is a screenshot of the error.
Regards,
Ann

Hi Ann,
Beside the Dynamic App Launcher Tile, you also need to add a target Mapping in your catalog.
Check if the target Launchpad role (Transaction LPD_CUST) exists in your SAP ECC system
Add an Target-Mapping Tile
•Add the Intent data
•Semantic Object WorkflowTask
•Action approveRequests
•Add Target data
•Launchpad Role UIX01CA1
•Launchpad Instance TRANSACTIONAL
•Application Alias ApproveRequests
•Add General Data
•Specify the supported form factor
Good luck, it works for me.

Struts 1.3.10 problem

Hello
I have a page that has two active portions, "feed" by session objects and iterated. It works fine monolithically. I now want to break it up into a frameset using the struts frame tag for the individual segmented portions. Before I launch to my frameset composed page, I land on a page that confirms that the two segments work, with an strut html:link. It also works, properly formatted with a sessionsID, and when click the page (either) correctly loads. When I jump to my frameset composed page it does not load, does not have the sessionID(reason it doesnt load), but no errors on compiler error. In the example below I show it with a forward, but it is the same/failure with either a properly defined forward or a simple page attribute. Any ideas? If I use Tiles will it not force a reload in one tile when another is submitted and posted back?
the crucial segment on the composed page is:
<html:link page="/inner.jsp" title="innerFrame">InnerFrame</html:link>
<html:link page="/static.jsp" title="staticFrame">staticFrame</html:link>
<frameset rows="85%,15%" id="enclosingFrame" title="totalFrame">
<html:frame forward="innerFrame" frameName="inner" styleId="innerFrame" marginwidth="0"/>
<html:frame forward="staticFrame" frameName="static" styleId="staticFrame" marginwidth="0"/>
</frameset>

Frames == Bad.
Use jsp:include or whatever include tag Struts provides (check their homepage/documentation for details).

Hi,
this question should be asked on the MyFaces Trinidad mail list as it uses the open source components currently in incubator.
http://wiki.apache.org/myfaces/ADF_Faces
Note that the ADF Faces components meanwhile are slightly different from the open source branch. This is an important distinction as you are using tiles.

About different ClassLoader in Applet

I have made an application which can reload updated class dynamically..
for reloading class dynamically from file system, I can't help using URLClassLoader which is different from original ClassLoader.
When the application works in local JVM, the diffrenent class loaders didn't make any problem .. but, when the application works as Applet in web, class loaders make some problems....
for example,
Class A {
protected String name;
public String getName(Class B) { return name; }
Class B {
URLClassLoader classLoader;
public void showName(){
A aClass = classLoader.loadClass("A");
Method method = aClass.getClass().getMethod("getName", this.getClass()); ----> 1
String name = (String)Method.invoke(aClass, this);
the part of 1 generates error :: NoMethodError.
that is the reasion that Class A is loaded from default system class loader,
and Class B is loaded dynamically from URLClassLoader.
but, above code works well in local JVM, but when I execute as Applet in Web,
it generates NoMethodError...
Is there any persion telling me the answer?

This is just a guess, but maybe it's a security issue in the browser ?
Try changing the settings in IE: tools, internetoptions, security, custom level, java permissions: custom
Then, enable 'run unsigned content' and enable 'access to all networkaddresses'

Change the colour of the tile dynamically:

Hi,
I have 12 tiles in my application. Depending upon some condition, few tiles colour should be changed and also to the same tiles image should be added. (I'm creating tiles using Border)
Can anybody suggest how can I achieve this?
Thanks,
Santosh

Please close your previous threads before you start a new one.
Also, you have asked this very same question before here:
https://social.msdn.microsoft.com/Forums/vstudio/en-US/b3752b09-2ee2-46ac-a941-dc7baad78110/change-the-colour-of-the-rectangle-dynamically?forum=wpf#b3752b09-2ee2-46ac-a941-dc7baad78110.
Please don't ask the same question twice.
You could use DataTriggers and/or converters to change the property of some UI element based on some condition as already suggested in the previous thread.
Of course you must post your code, or even better upload a reproducable sample of your issue to OneDrive and post the link to it here, for anyone to be able to provide a specific solution.
But note that the forums are not for anyone else to do the entire work for you. You were given code samples of how to use data triggers and converters in the previous thread. That should certainly give you the idea.
Please remember to close your threads by marking helpful posts as answer and please start a new thread if you have a new question.

Ejb dynamic reloading

Hello
I read about ejb dynamic reloading in a few places in ias documentation and
i have the following quastions:
- what will happen if i change deployment descriptors of ejb?
- what will happen if i change some other classes like value object classes
or other helper classes?
- what will happen if i change remote or home interface of ejb?
Does dynamic reloading work in that sytuation?
I also found that I have to call create method for stateless session bean
and entity bean to reflect the changes of dynamic reloading. Is it true?
Artur

Hi Artur,
Please find answer inline.

Dynamic reloading works fine if you change only in Bean Implementation
class. It does not support change in Home, Remote Interface or any other
helper class.
I also found that I have to call create method for stateless session bean

Yes it's absolutely correct.

Dynamic class reloading in modular web application

Hi.
My web application has these requirements:
A. Functional modularization (like plug-ins). Modules will be simple jars containing application logic classes: dto beans, business logic services, dao (jpa), framework stuff (Struts2), etc...
B. At runtime and without restarting the application "class loading" must be aware of classes inside new, changed and removed modules.
C. Some of these jars will be outside the web application folder (WEB-INF/lib), possibly outside the container itself too.
My question:
1. Can I achieve all or some of my requirements with a Java web application?
2. How should I manage the modules?
3. Do I need some special web container feature (maybe osgi)?
4. Can I use a custom class loader in my application?
The architecture objectives are:
I. Provide scalability.
II. Efficient development process (independent deployment and no application restart required).
III. Better production support (no application restart required for changes).
More on the architecture:
a). Functional scalability, meaning this that my application may functionally grow up to an indeterminate number of small functional modules.
b). Modules will be developed, deployed and maintained independently so the application discovers and loads classes on demand.
c). Avoid a big .war file containing all the small modules because a small change in one module would involves deploying all the other modules (possibly hundreds o even thousands of them) and restarting the application.
d). Above point involves dynamic class reloading.
I guess this is addressed by OSGI (looks like heavy to deal with), Jigsaw (still under development) and maybe others. I think the key point is the class loader. I will develop a custom class loader but maybe you have some advice for me before starting to develop.
Thanks and regards.

Classes maintained by the container should not be loaded by an application. You want the container to read those classes and react accordingly. Most of those classes are read when the container starts up a container restart will be required. Trying to leverage another container within a container does not sound like it will be worth (if you can get it to work).
Perhaps you should state the problem that you are trying to solve with these modules so that others may suggest more feasible solutions to achieve your target goals.

Dynamic reloading in iWS 6.0 causes my http session to be lost

Hi,
I have a problem with dynamic reloading in iWS 6.0 Sp2 on Solaris 8. I have not set the reload-interval for the class-loader, in fact i haven't included anything related to the classloader in the web-apps.xml file.
The default behaviour is observed, the classes are reloaded every 30 seconds. So far, so good.
I have seen that if a change a class, iWS reloads the entire application, destroying all the servlets in it. This destroys my HTTP session.
The same behaviour is observed in a redeployment, and in a reloading of config files.
Is there any way of avoiding this?
Thanks.
By the way, could anyone describe the classloader architecture of iWS.
Juan

Scott,
Does the problem only occur on MSIE clients? Do this work properly on Communicator? If so, you may be running into a problem with how MSIE determines the maxage for a cookie.
The criteria that IE uses for creating a new session is the length of time that a session has been alive. For this reason, when a user tries to connect to a web application on the iWS webserver through IE, the time on the client server and on the webserver must be set correctly. Otherwise, the user could experience problems with session data getting lost or discarded by the client.
This problem does not occur on Netscape browsers, as Netscape browsers set the cookie using the client-side clock and the maxage sent by the server.
Refer to this technote and see if the helps:

HTML Tile loaded dynamically based on user interaction is invisible

When I include an HTML Tile in my application XML file, it shows up fine. When I load it dynamically, it doesn't throw a runtime error but it's invisible.
Thoughts?
Thanks in advance!

Here's how I'm loading the tile:
private function onDataGridSelectionSignalReceived():void
    trace("onDataGridSelectionSignalReceived");
    //To read HTML tile from Catalog
    var htmlTile:ITile = mosaicApp.loadedCatalogs[0].tiles[4];
    htmlTile.visible = true;
    var shellPanelParent:IShell = mosaicApp.shell;
    //Itegrate main panel
    for each (var mainPanel:IPanel in shellPanelParent.panels)
        //Iterate content panel
        for each (var contentPanel:IPanel in mainPanel.panels)
            //we are reading existing message tile due to panel alignment issue
            //and this will be again added to the panel as last component.
            var messageTile:ITile = contentPanel.removeTile(contentPanel.tiles[1]);
            //To add HTML tile into panel
            contentPanel.addTile(htmlTile as ITile);
            //To add Message tile into panel
            contentPanel.addTile(messageTile);
            //To remove SearchTile from panel
            contentPanel.removeTile(contentPanel.tiles[0]);
