Suggestion: Better navigation between "applets"

Once you've drilled down into any particular "applet" on
acrobat.com, it's hard to get back to the others, or back to the
main "menu".
I think the applets need to have at least knowledge of the
"main menu", and a way to get back to it.
Howard

I agree entirely. There needs to be a better way to drill
into an application and then return back to the main "menu."

Navigating between applets from the same signed jar (trusted CA) gives err

See [http://www.chrisnewland.com/java-7-update-21-signedunsigned-error-switching-between-applets-in-the-same-signed-jar-trusted-ca-339] for my investigations so far.
Clicking a link to navigate between applets contained in the same signed jar (signed by a trusted CA) pops up an error dialog complaining about a signed/unsigned code mix.
Loading each applet in a fresh browser works fine.
If you click from applet 1 to applet 2 via a non-applet page then both applets run without problem.

How to navigating between layers?( as if they were pages of a book?)

I need a good advice on design and navigating between some different layers.
I am a Adobe Director user, and I am used to think of “navigating between frames”. also frames as pages of a book, while in flash time-frames.
In Director one can navigate between different frames with each containing many components.
And this does not make any conflict since the frames are some kind of pages of a book, you go to any page you want and back again.
I am designing math training application in falsh-CS6, in which the user should be able to navigate from start-menu by choosing an
exercise number and then go to the wanted exercise and then create an exercise by a create_excercise button, there back again to menu to choose another and so on. How I can do it clean in flash?
As I see I have to place everything in the same “frame” in flash, and it becomes little practical and confusing since there
are many things all gathered in the same frame, where they should instead appear in their respective “pages”.
I have done some works in flash: made 4 layers in flash with the following contents:
layer 1: for my menu( contains 3 buttons, q1bt, q2bt, q3bt)
layer 2: for question 1( contains 3 buttons makeQ1bt, chekAns1bt, and gotoMenuBtn)
the same is for layer 3 and 4.
I see no options rather than making different components visible or invisible whole way! but is there a better way?
I appreciate any help.

Flash does allow more than one frame - that is one of the foundations of working with it. You can restrict yourself to using just one frame if you like, but it is not required and very often people use the timeline instead of keeping things in one place.
I have no familiarity with Director, but what you just described sounds like designing using the timeline of Flash. With Flash you can use the timeline in the fashion you just described where different pages occupy different frames of the timeline and you can navigate from one to another. You are not stuck with one frame in Flash... you can create a new keyframe at any point along the timeline and add new/different content to it, while retaining a menu that exists across all pages (or not - it's your choice)..

Navigation between different componets in IC Web Client for CRM 7.0

Once the user click save button in component ICCMP_BT_BUTTON I need to navigate to component ICCMP_BT_SVO that displays the Service Order Data and display the new Service Request that was created.
How can I do navigation between different componets in IC Web Client for CRM 7.0?
Thanks.

Hello,
You can find detailed presentations in the learning maps available on the SAP Service Marketplace http://service.sap.com/rkt-crm for release CRM 2006s, CRM 2007, or CRM 7.0. In case I didn't mention it before, Intent-Driven Interaction (IDI) was first introduced and is only available starting with CRM 2006s and above. In the Interaction Center area, there is a presentation called "Rule Based Automation and Guidance" which covers IDI. I'm not sure if you can access the URL directly, but just in case here it is: [https://websmp104.sap-ag.de/~sapidb/011000358700001162852007E].

Navigation between records in a JSP application

Hi,
I would like to know how to provide navigation between records in a tabular form liked JSP application using JDeveloper 3.2
without using the Oracle or Default template.
I can do it with a singular record view but not in a tabular view. I like to know now I can mimic the navigation provided in Oracle template in which the current selected record is hightlighted. Can we navigate between records using Up and Down
arrow key like in Oracle form instead of using Navigation Bar. Please provide details code.
Thanks a bunch,
Khanh Hoang

You can refer to the source code in jbohtmlsrc.zip for deriving your own implementation.

Better Value between Macbook Pro 17 inch stock or 27inc iMac i5 stock

I need some help, which would be the better value between a stock 17inch macbook pro and a stock i5 27inch iMac? Using it for school, small video and picture editing. Price not a concern, I'm just looking for the better value in the computer itself. Meaning resale, upgradeability, (plan to use for at least the next three years)!

I'm saying to myself why spend the additional $500 for a slower machine?
Um...because it's portable? Because if there's a blackout you can still use it for 8 hours? Because if you travel to another country you can still do your video editing there rather than waiting to get home with all that film and photography to do it? Because it fits in a bag and doesn't require a desk? Because it can be hooked up to larger monitors for presentations in class?
I mean, Dude, it may not seem like a "slower" machine is worth $500, but it's not cheap or easy to make something that is as fast and does as much as that 17" does in something that thin and that light. There is a battery, a camera, an light sensitive keyboard, a gorgeous screen, and all the other components squeezed into that narrow and limited diameter...and you think that's not wroth $500 extra dollars because it's slower than a 27" iMac? If you love the speed and power, go 27" iMac. It's a great, great, machine. Awesomely fast, powerful and beautiful. But don't tell us "cost doesn't matter" and "resale" is what you're interested in and then complain about the 17" costing extra but being slower. You're being dishonest about what matters to you there.
If cost of the machine and its speed matters (far more than portability)--and you want the fastest and cheapest, then it's the 27" iMac. If cost doesn't matter, and you want the best resale value for when you sell the machine after three years, then it's the 17" MBP. That's just how the market is. People like speed yes, but they love portability.
Edited to add: but you might want to wait. Many are saying that the MBP might get a bump to an i5 and that would improve the speed of a 17" considerably.

Code sharing between applets

Hi,
I'm currently using Eclipse and JCOP plugin for applet development, and I'm looking for solutions on how to share custom libraries between applets. I'm particularly not looking for interface sharing between applets, but more how to organize the source code so I can include common custom classes in different applets (e.g. generic ASN1 parsing library, signature library etc)
Thank you for any feedback.

Thanks for the pointer! I also found this thread:
https://forums.oracle.com/thread/2217928?start=0&tstart=0
which cover the same topic with code examples to be very useful.
But I have stumbled upon a couple of problem wrt this approach which I can't quite isolate:
1. I've got a shell script which basically "tags" a package before build with the SVN version number, and if there are local modifications. This code is auto-generated in a file called svnversion.java inside commonlib package:
package commonlib;
public class svnversion {
public static final byte[] TAG = {(byte) 0x00 ,(byte) 0xFB ,(byte) 0x3F } ;
public static final boolean MODIFIED = true ;
When this code was in the same package as the applet, I had no problem accessing the TAG byte array, but after separating the applet and the commonlib in two separate packages, I get SW 0x6f00 whenever I touch the TAG byte array from my applet. I can access the MODIFIED variable, but not the TAG byte array.
(EDIT: Since commonlib declare TAG as a static final byte array, and final cannot be set to null upon release, maybe this is the cause for my memory leaks?)
2. I try to keep everything in commonlib static, and I've added an install() and release() hook in commonlib which keeps track of reference counter and acquire and release memory. Upon release I set every static variable to null. And I call commonlib.install() from the applet, and use AppletEvent and do commonlib.release() upon uninstall. But still it seems I fail to clean-up properly, because I end up in situations where I'm unable to delete the card content - presumably because a memory leak. So I have a few questions related to that:
a) How do I debug memory leaks?
b) In commonlib, if I do:
public class Common {
     private static DESKey des1Key = null;
     private static short refCount = 0;
     public static void install() {
          refCount++;
          if (des1Key == null)
               des1Key = (DESKey) KeyBuilder.buildKey(KeyBuilder.TYPE_DES, KeyBuilder.LENGTH_DES, false);
public static void release() {
     --refCount;
     if (refCount == 0)
          des1Key = null;
Is it a correct assumption that I need to set des1Key to null, because it is declared as static?
c) Does the following code snippets allocate memory, which needs to be freed?
md = MessageDigest.getInstance(MessageDigest.ALG_SHA_256, false);
and
rsaCipher = Cipher.getInstance(Cipher.ALG_RSA_NOPAD, false);
d) Say commonlib should hold one RSA key, but at install time we do not know the key size (actual size shall be requested by client). I chose this approach:
public class RSAlib {
     public static KeyPair rsaKeyPair = null;
     public static Cipher rsaCipher = null;
private static short refCount = 0;
     public static void install() {
refCount++;
          if (rsaCipher == null) {
              rsaCipher = Cipher.getInstance(Cipher.ALG_RSA_NOPAD, false); }
     public static void release() {
          --refCount;
          if (refCount==0) {
               rsaCipher = null;
               rsaKeyPair = null;
public static void createRSAKeyPair(short keySize) {
     switch(keySize) {
     case (KeyBuilder.LENGTH_RSA_1024):
     case (KeyBuilder.LENGTH_RSA_2048):
          break;
     default:
          ISOException.throwIt(SW.CRYPTOGRAPHIC_ERROR);
     try {
          JCSystem.beginTransaction();
          rsaKeyPair = new KeyPair(KeyPair.ALG_RSA_CRT, keySize);
          JCSystem.requestObjectDeletion();
          JCSystem.commitTransaction();
     } catch (Exception e) {
          JCSystem.abortTransaction();
Is this correct usage of garbage collection (I know my JCOP card support it), and will this work in context of a commonlib?

Large number of http posts navigating between forms

Hi,
i'm not really a forms person (well not since v3/4 running character mode on a mainframe!), so please be patient if I'm not providing the most useful information.
An oracle forms 10 system that I have fallen into supporting has to me very poor performance in doing simple things like navigating between forms/tabs.
Looking at the java console (Running Sun JRE 1.6.0_17), and turning on network tracing, I can see a much larger number of post requests than I would expect (I looked here first as initially we had an issue with every request going via a proxy server, and I wondered if we had lost the bypass proxy setting). Only a normal number of GETS though.
Moving to one particualr detail form from a master record is generating over 300 post requests - I'v confirmed this looking at the Apache logs on the server. This is the worst one I have found, but in general the application appears to be extremely 'chatty'
The only other system I work with which uses forms doesn't generate anything like these numbers of requests, which makes me think this isn't normal (As well as the fact this particular form is very slow to open)
This is a third party application, so i don't have access to the source unfortunately.
Is there anything we should look at in our setup, or is this likely to be an application coding issue? This app is a recent conversion from a forms 6 client server application (Which itself ran ok, at least this bit of the application did with no delays in navigation between screens).
I'm happy to go back to the supplier, but it might help if I can point them into some specific directions, plus i'd like to know what's going on too!
Regards,
Carl

Sounds odd. 300 Requests is by far too much. As it was a C/S application: did they do anything else except the recompile on 10g? Moving from C/S to 10g webforms seems to be easy as you just need to recompile but in fact it isn't. There are many things which didn't matter in a C/S environment but have disastrous effects once the form is deployed over the web. The synchronize built in for example. In C/S calls to synchronize wasn't that bad; But when you are using web deployed forms...each call to synchronize is a roundtrip. The usage of timers is also best kept on a low level in webforms for example.
A good starting point for the whole do's and dont's when moving forms to the web is the forms upgrade center:
http://www.oracle.com/technetwork/developer-tools/forms/index-095046.html
If you don't have the source code available that's unfortune; but if you want to know what's happening behind the scenes there is the possibility to trace a forms session:
http://download.oracle.com/docs/cd/B14099_19/web.1012/b14032/tracing002.htm#i1035515
maybe this sheds some light upon what's going on.
cheers

Retaining values when navigating between subtabs

Hello everyone
I have a subtab region with 3 tabs in my page. I have some form fields in each tab, when I enter some details in tab1 and click tab2, and then come back to tab1 , my details previously entered in tab1 gets cleared. is there a way to retain these values when navigating between subtabs. all the tabs are based on different VO's
Thanks
Ravi

Here's how I do it...
(1) I always use Sessions. In the main form of my application, I set up the session and I store a single variable: Session.Exists = True. All other forms begin something like this: (It's actually an include-file.)
<cflock ...>
<cfset SessionExists = StructKeyExists(Session, "Exists")>
</cflock>
<cfif NOT SessionExists>
<cflocation ... send 'em back to the home 'cuz their session has expired>
<cfabort>
</cfif>
(2) Now that we know that a session exists, we store various structs in the Session to contain the default or current values that have been used in a particular form. If the Session scope does not contain a particular struct, it is automagically created with appropriate default values.) This becomes "what we display," and when we capture the user's responses, we store them there, even before we validate them. The session pool therefore becomes the vehicle for communication between the various forms.
(3) If we reach a point where a particular piece of information is no longer useful, we delete the appropriate structure from the Session, thereby wiping out the entire set of values at once.
(4) Structs and Arrays can, of course, contain other Structs and Arrays. You can build data structures of arbitrary complexity.
(5) As of late, I have found myself specifying individual CFCs for each logical "object" in my application. This is true object-oriented programming, as best as ordinary CFC techniques can do without plunging headlong into the underlying nether-world of Java. In those CFCs, I deliberately try to conceal just how information is maintained and stored, so that these necessary inter-dependencies within my application are concentrated in just one place. "The structure is 'the object,' and the methods are found 'here and only here.' "

How to remove white fade while navigating between pages?

I created small web page with 4 buttons which each of them leads to other page eg., Home,Gallery, Contacts,Reviews, but when i'm navigating between them there is annoying white flash! Is it possible to remove it?
P.S. I uploaded my site to businesscatalyst Home
Thank you!

That is so strange, I just tried on my OS X Safari and WIN 7 Chrome and everything just fine, but when I'm trying on same OS X Chrome it has white flash while transitioning through navigation. Thanks anyway mac_heibu!
