Using setParam in the XSLStyleSheet class?
How can I make use in the stylesheet of a paramater set with this method? Is it even possible to do this?
Actually, you would make use of it the same way as you would a parameter set with xsl:param in a top level element.

Flash Player use to execute the main class entry point before rendering. Now it does not
Adobe Flash Player use to execute the main class entry point before rendering the first frame. Now using the latest browsers and Flash Player 11.8 (11.8.800.94, or 11.8.800.97 for Chrome).
With one of our swf apps, there are visual display objects on the first frame of the timeline. When the main class constructor is executed, those display objects are set to visible = false. So previously those display objects were never displayed because the first frame did not render until after the main class code was ran.
Now when we browse to the our website, we find that those display objects are visible for a split moment of time (such as a quarter of a second).
It appears that this may be a bug. We are wondering this could be new behavior based on loading/unloading the swf to optimize CPU usage and that Flash Player is taking a snapshot of the internal state of the first frame and displaying the cached snapshot before it actually loads.
So...Chris (or other Adobe representative), is Flash Player supposed to be rendering the display before any code executes it runs the main class?Not that I'm aware of. If this is something that just started with 11.8, then we could be running into some sort of bug injection. Could you please open a new bug report on this over at bugbase.adobe.com? When adding the bug, please include sample code, application or URL so we can quickly test this out internally. If you'd like to keep this private, feel free to email the attachment to me directly ([email protected]).
Once added, please post back with the bug number and we'll investigate from there. -
How to use logging in the actions classes extends standart actions?
Hello!
I have some action classes extends standart actions, for example Z_ExtMaintainBasketDispatcherAction extends MaintainBasketDispatcherAction. I tried to use logging functionality in my classes but there were no my lines in log and trace files.
For example I added followed lines in basketPerform() method of Z_ExtMaintainBasketDispatcherAction:
boolean isDebugEnabled = log.isDebugEnabled();
if(isDebugEnabled){
log.debug("++++++++++++++++ Test tracing in B2B_SNG. ++++++++++++++++");
but in there was no such line neither in log file nor in trace file.
How I can use logging functionality in my own classes? I need it for tracing and logging.
CRM 5.0
regards, LevWell, here is solution. I created a log formatter and log destination like this:
<log-formatters>
<log-formatter name="application_sap.com/crm~b2b" type="TraceFormatter" pattern="%d,%-3p %t %s %l %m"/>
</log-formatters>
<log-destinations>
<log-destination name="application_sap.com_crm.b2b" type="FileLog"
count="10" effective-severity="ALL" limit="10000000" pattern=".\log\applications\isa_ru.log">
<formatter-ref name="application_sap.com/crm~b2b"/>
</log-destination>
</log-destinations>
and new log controller like this:
<log-controller effective-severity="ALL" name="ru.sng.isa">
<associated-destinations>
<destination-ref name="application_sap.com_crm.b2b" association-type="LOG"/>
</associated-destinations>
</log-controller>
in file META-INF\log-configuration.xml
Thanks everybody for help!

How to use the Rectangle class to draw an image and center it in a JPanel
I sent an earlier post on how to center an image in a JPanel using the Rectangle class. I was asked to send an executable code which will show the malfunction. The code below is an executable code and a small part of a very big project. To simplifiy things, it is just a JFrame and a JPanel with an open dialog. Once executed the JFrame and the FileDialog will open. You can then navigate to a .gif or a .jpg picture and open it. What I want is for the picture to be centered in the middle of the JPanel and not the upper left corner. It is also important to stress that, I am usinig the Rectangle class to draw the Image. The region of interest is where the rectangle is created. In the constructor of the CenterRect class, I initialize the Rectangle class. Then I use paintComponent in the CenterRect class to draw the Image. The other classes are just support classes. The MyImage class is an extended image class which also has a draw() method. Any assistance in getting the Rectangle to show at the center of the JPanel without affecting the size and shape of the image will be greatly appreciated.
I have divided the code into three parts. They are all supposed to be on one file in order to execute.

Weird one.. i can't return a variable from the extended to the super class
Hey everyone, i hope i'm not annoying you guys :)
So today's problem is to return a variable (int) from a method of the extended class and print it ont the super class.
I'm just testing the super class , if it works fine.
So the extended class ( FileIO) just read the file txt and return the integer or string ( from the txt file)
I already did a main method to that class and tested it, it works fine.
So now the problem is to print the integer ( that the extended class gets from the txt. ) inside the Super class. I mean , is the same thing but now im testing the Super class , just have to do the same thing, a super class method calls the extended class method and receive the integer from the txt file.
i think the problem is when i create the instance of the FileIO object , maybe its constructor ...i don't know.
The name of the txt file is passed from the super class to the extended class, but i think the error is not from there.
this.aero_le = new BufferedReader(new FileReader(super.ficheiroleitura_aero())); // super calls ficheiroleitura_aero() and receive the name of the txt file ( e.g "temp.txt") so i think that is correct.
here's the code of the Super class public class Aeroporto {
private String filereader_voo = "temporary.txt";
private String filereader_aero = "temp.txt";
private String siglaAero = "";
public FileIO file;
public Aeroporto(){};
public Aeroporto(String filereader_voo, String filereader_aero) throws IOException{
this.filereader_voo = filereader_voo;
this.filereader_aero =filereader_aero;
file = new FileIO();
public String siglaAero() {
return siglaAero; }
public String filereader_aero(){
return filereader_aero;
public int nrLines() throws IOException{ // it was supose to retunr the number of lines ( integer) from the txt file .
return Integer.parseInt(file.lerLinhaN(1,1));
// main() {
Aeroporto a = new Aeroporto();
int v = a.nrLines();
System.out.print(v);
// ***********************************************************+
// Extended Class
public class FileIO extends Aeroporto{
private String ficheiroescrita;
private PrintWriter vooescreve, aeroescreve ;
private BufferedReader voo_le, aero_read;
public FileIO(){}
public FileIO(String filereader_voo, String filereader_aero, String ficheiroescrita) throws IOException {
super(filereader_voo, filereader_aero);
this.ficheiroescrita = ficheiroescrita;
//If file does not exists , create one.
try{
this.aero_read = new BufferedReader(new FileReader(super.filereader_aero()));
aero_read.close();
catch(IOException ex){
this.aeroescreve = new PrintWriter(new FileWriter(ficheiroescrita));
aeroescreve.close();
public String lerLinhaN(int line, int column) throws IOException{ // this method works fine , i already tested this class.
this.aero_read = new BufferedReader(new FileReader(super.filereader_aero()));
for(int i = 0; i != line-1; ++i) aero_read.readLine();
String linha = aero_read.readLine();
String [] words = linha.split(" ");
return words[column-1];
Maybe the error is that i use to test the Super class a default contructor on both classes... i don't know where the error is, i also did two small classes ( super and another that extends ) and get the string "Hello" from the super and print it inside the extended..and it works, that's why i think the error is when i call the extended class .. need help.

}Design notes... FileIO is a generic helper class... there is nothing specific to Airports, flights, or any other "domain" specific stuff in it... so it's re-usable... you can keep it and reuse it on other projects, or even share it with your friends.
So... The airport class will just call the static methods on FileIO like this ....
int lineNumber=1;
int wordNumber=1;
String airportCode = FileIO.readWord(airportsFilename, lineNumber, wordNumber);
....How's that?

Tracking Memory usage on iOS using the Stats class
I've been checking memory usage on an app I'm developing for iOS using the Stats class https://github.com/mrdoob/Hi-ReS-Stats ( http://help.adobe.com/en_US/as3/mobile/WS4bebcd66a74275c3-315cd077124319488fd-7fff.html#WS 948100b6829bd5a61637f0a412623fd0543-8000).
I added the Stats class to my project and redeployed and, yikes, memory usage reported in Stats creeps up (pretty slowly) even when there's nothing happening in the app (just showing a loaded bitmap).
To try and track down the issue I created a project with a test class that extends Sprite with just this single call in the constructor :-
addChild( new Stats() );
I deployed it to the device to check that it didn't gobble any memory.
But I was Suprised to watch the memory usage creep up and up (to approx 5) before some garbage collection kicked in and takes memory back down. I left it running and then it crept up again to over 7.5 this time before being kicked back down to just below 3.
So 2 related questions that I'd appreciate any feedback/observations/thoughts on :-
1 - Is this normal (i.e. memory creeping up when there's nothing other than Stats in the project) ?
2 - What is the best way to monitor memory usage within an app ? Is Stats good enough - is Stats itself causing the memory usage ?
All the best guys !Also see thread (http://forums.adobe.com/message/4280020#4280020)
My conclusions are :-
- If you run an app and leave it idle, memory usage gradually creeps up (presumably as memory is being used to perform calcs/refresh the display etc)
- Periodically the garbage collection kicks in and memory is brought back down
- This cycle could be in excess of 5 mins
Run with your real app and memory will increase and be released much more rapidly/regularly.
- It's probably worth performing initial checks by running on your desktop to iron out any initial problems -
Namburi,
When you said you used the Reg Exp tool, did you use it only as
preconfigured by the iMT migrate application wizard?
Because the default configuration of the regular expression tool will only
target the files in your ND project directories. If you wish to target
classes outside of the normal directory scope, you have to either modify the
"Source Directory" property OR create another instance of the regular
expression tool. See the "Tool" menu in the iMT to create additional tool
instances which can each be configured to target different sets of files
using different sets of rules.
Usually, I utilize 3 different sets of rules files on a given migration:
spider2jato.xml
these are the generic conversion rules (but includes the optimized rules for
ViewBean and Model based code, i.e. these rules do not utilize the
RequestManager since it is not needed for code running inside the ViewBean
or Model classes)
I run these rules against all files.
See the file download section of this forum for periodic updates to these
rules.
nonProjectFileRules.xml
these include rules that add the necessary
RequestManager.getRequestContext(). etc prefixes to many of the common
calls.
I run these rules against user module and any other classes that do not are
not ModuleServlet, ContainerView, or Model classes.
appXRules.xml
these rules include application specific changes that I discover while
working on the project. A common thing here is changing import statements
(since the migration tool moves ND project code into different jato
packaging structure, you sometime need to adjust imports in non-project
classes that previously imported ND project specific packages)
So you see, you are not limited to one set of rules at all. Just be careful
to keep track of your backups (the regexp tool provides several options in
its Expert Properties related to back up strategies).

Thanks Matt, Mike, Todd
This is a great input for our migration. Though we used the existing
Regular Expression Mapping tool, we did not change this to meet our
own needs as mentioned by Mike.
We would certainly incorporate this to ease our migration.

Great response. By the way, the Regular Expression Tool uses thePerl5 RE
syntax as implemented by Apache OROMatcher. If you're doing lotsof these
sorts of migration changes manually, you should definitely buy theO'Reilly
book "Mastering Regular Expressions" and generate some rules toautomate the
conversion. Although they are definitely confusing at first,regular
expressions are fairly easy to understand with some documentation,and are
superbly effective at tackling this kind of migration task.

Subject: Re: [iPlanet-JATO] Use Of models in utility classes -Pease don't

Also, (and Matt's document may mention this)
Please bear in mind that this statement is not totally correct:
Since the migration tool does not do much of conversion for
these
utilities we have to do manually.Remember, the iMT is a SUITE of tools. There is the extractiontool, and
the translation tool, and the regular expression tool, and severalother
smaller tools (like the jar and compilation tools). It is correctto state
that the extraction and translation tools only significantlyconvert the
primary ND project objects (the pages, the data objects, and theproject
classes). The extraction and translation tools do minimumtranslation of the
User Module objects (i.e. they repackage the user module classes inthe new
jato module packages). It is correct that for all other utilityclasses
which are not formally part of the ND project, the extraction and
translation tools do not perform any migration.
However, the regular expression tool can "migrate" any arbitrary
file
(utility classes etc) to the degree that the regular expressionrules
correlate to the code present in the arbitrary file. So first andforemost,
if you have alot of spider code in your non-project classes youshould
consider using the regular expression tool and if warranted adding
additional rules to reduce the amount of manual adjustments thatneed to be
made. I can stress this enough. We can even help you write theregular
expression rules if you simply identify the code pattern you wish to
convert. Just because there is not already a regular expressionrule to
match your need does not mean it can't be written. We have notnearly
exhausted the possibilities.
For example if you say, we need to convert
CSpider.getDataObject("X");
To
RequestManager.getRequestContext().getModelManager().getModel(XModel.class);
Maybe we or somebody else in the list can help write that regularexpression if it has not already been written. For instance in thelast
updated spider2jato.xml file there is already aCSpider.getCommonPage("X")
rule:
<!--getPage to getViewBean-->
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getViewBean($1ViewBean.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
Following this example a getDataObject to getModel would look

In fact, one migration developer already wrote that rule andsubmitted it
for inclusion in the basic set. I will post another upgrade to thebasic
regular expression rule set, look for a "file uploaded" posting.Also,
please consider contributing any additional generic rules that youhave
written for inclusion in the basic set.
Please not, that in some cases (Utility classes in particular)
the rule
application may be more effective as TWO sequention rules ratherthan one
monolithic rule. Again using the example above, it will convert
CSpider.getDataObject("Foo");
To
getModel(FooModel.class);
Now that is the most effective conversion for that code if that
code is in
a page or data object class file. But if that code is in a Utilityclass you
really want:
>
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
So to go from
getModel(FooModel.class);
To
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
You would apply a second rule AND you would ONLY run this rule
against
your utility classes so that you would not otherwise affect yourViewBean
and Model classes which are completely fine with the simplegetModel call.
<mapping-rule>

A similer rule can be applied to getSession and other CSpider APIcalls.
For instance here is the rule for converting getSession calls toleverage
the RequestManager.

Namburi,
I will post a document to the group site this evening which has
the
details
on various tactics of migrating these type of utilities.
Essentially,
you
either need to convert these utilities to Models themselves or
keep the
utilities as is and simply use the
RequestManager.getRequestContext.getModelManager().getModel()
to statically access Models.
For CSpSelect.executeImmediate() I have an example of customhelper

as a replacement whicch uses JDBC results instead of
CSpDBResult.

Subject: [iPlanet-JATO] Use Of models in utility classes
Hi All,
In the present ND project we have lots of utility classes.
These
classes in diffrent directory. Not part of nd pages.
In these classes we access the dataobjects and do themanipulations.
So we access dataobjects directly like
CSpider.getDataObject("do....");
and then execute it.
Since the migration tool does not do much of conversion forthese
utilities we have to do manually.
My question is Can we access the the models in the postmigration
sameway or do we need requestContext?
We have lots of utility classes which are DataObjectintensive. Can
someone suggest a better way to migrate this kind of code.
Thanks

[email protected]Namburi,
When you said you used the Reg Exp tool, did you use it only as
preconfigured by the iMT migrate application wizard?
Because the default configuration of the regular expression tool will only
target the files in your ND project directories. If you wish to target
classes outside of the normal directory scope, you have to either modify the
"Source Directory" property OR create another instance of the regular
expression tool. See the "Tool" menu in the iMT to create additional tool
instances which can each be configured to target different sets of files
using different sets of rules.
Usually, I utilize 3 different sets of rules files on a given migration:
spider2jato.xml
these are the generic conversion rules (but includes the optimized rules for
ViewBean and Model based code, i.e. these rules do not utilize the
RequestManager since it is not needed for code running inside the ViewBean
or Model classes)
I run these rules against all files.
See the file download section of this forum for periodic updates to these
rules.
nonProjectFileRules.xml
these include rules that add the necessary
RequestManager.getRequestContext(). etc prefixes to many of the common
calls.
I run these rules against user module and any other classes that do not are
not ModuleServlet, ContainerView, or Model classes.
appXRules.xml
these rules include application specific changes that I discover while
working on the project. A common thing here is changing import statements
(since the migration tool moves ND project code into different jato
packaging structure, you sometime need to adjust imports in non-project
classes that previously imported ND project specific packages)
So you see, you are not limited to one set of rules at all. Just be careful
to keep track of your backups (the regexp tool provides several options in
its Expert Properties related to back up strategies).

This is a great input for our migration. Though we used the existing
Regular Expression Mapping tool, we did not change this to meet our
own needs as mentioned by Mike.
We would certainly incorporate this to ease our migration.

Great response. By the way, the Regular Expression Tool uses thePerl5 RE
syntax as implemented by Apache OROMatcher. If you're doing lotsof these
sorts of migration changes manually, you should definitely buy theO'Reilly
book "Mastering Regular Expressions" and generate some rules toautomate the
conversion. Although they are definitely confusing at first,regular
expressions are fairly easy to understand with some documentation,and are
superbly effective at tackling this kind of migration task.

Also, (and Matt's document may mention this)
Please bear in mind that this statement is not totally correct:
Since the migration tool does not do much of conversion for
these
utilities we have to do manually.Remember, the iMT is a SUITE of tools. There is the extractiontool, and
the translation tool, and the regular expression tool, and severalother
smaller tools (like the jar and compilation tools). It is correctto state
that the extraction and translation tools only significantlyconvert the
primary ND project objects (the pages, the data objects, and theproject
classes). The extraction and translation tools do minimumtranslation of the
User Module objects (i.e. they repackage the user module classes inthe new
jato module packages). It is correct that for all other utilityclasses
which are not formally part of the ND project, the extraction and
translation tools do not perform any migration.
However, the regular expression tool can "migrate" any arbitrary
file
(utility classes etc) to the degree that the regular expressionrules
correlate to the code present in the arbitrary file. So first andforemost,
if you have alot of spider code in your non-project classes youshould
consider using the regular expression tool and if warranted adding
additional rules to reduce the amount of manual adjustments thatneed to be
made. I can stress this enough. We can even help you write theregular
expression rules if you simply identify the code pattern you wish to
convert. Just because there is not already a regular expressionrule to
match your need does not mean it can't be written. We have notnearly
exhausted the possibilities.
For example if you say, we need to convert
CSpider.getDataObject("X");
To
RequestManager.getRequestContext().getModelManager().getModel(XModel.class);
Maybe we or somebody else in the list can help write that regularexpression if it has not already been written. For instance in thelast
updated spider2jato.xml file there is already aCSpider.getCommonPage("X")
rule:
<!--getPage to getViewBean-->
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getViewBean($1ViewBean.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
Following this example a getDataObject to getModel would look
like this:
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>

The best way to remove TM files is via the TM interface: select the files and click the Gear and select delete from all backups.
If you are deleting files on an external drive which once included TM files, it is best to use the terminal and just delete them directly. They go bye-bye without ever seeing the trash bucket.
Of course, using the terminal is not for everyone.
What you might be able to do is restore the files from trash and then delete them properly or in smaller bundles. -
Can i create more than one attributes for the custom class created using java API
Hello everyone,
I have been creating class and its attributes programatically using java APIs, I want to know that is there any way to create multipal attributs for the same class in just one call of API with all the options for each attributes,
thanksYou can create a new class and define all of the Attributes at the time the class is created - this is the preferred way of creating classes. Use the addAttributeDefinition() method on ClassObjectDefinition. If you need to add attributes to existing classes, you can only add them one at a time (using the addAttribute() method on ClassObject).

How to use the implementation class in property palette to display the PJC
Thanks,
Ansaf.The Implementation Class must reflect the full name of the class. For instance, if the full class name is : xx.yyy.zz.class_name, then put this in the Implementation Class property of the corresponding item.
Also, the class must be stored in the equivalent directory structure, so that, in my example: <DEV_HOME>/forms/java/xx/yyy/zz

What is the advantage of using IB to create XIBs/Class Objects over coding?
Hi all,
I hoping someone can provide me some pros and cons as to when I should use IB to create XIBs and/or class objects as opposed to directly coding them.
For example, if I choose Apple's Template for creating a Navigation Based Application (cocoa touch), the project creates two NIB files - MainMenu and RootViewController.
However looking at one of demo apps SimpleDrillDown, it does not have a RootViewController XIB and instead creates it via code.
Another example from the same two apps is that the template generates a "Navigation Controller" class object in the Mainmenu.xib. SimpleDrillDown does not bother with this in the XIB, but uses code to generate the controller:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Create the navigation and view controllers
RootViewController *rootViewController = [[RootViewController alloc] init];
UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
self.navigationController = aNavigationController;
[aNavigationController release];
[rootViewController release];
// Configure and show the window
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
as opposed to the template which only needs this:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Configure and show the window
// Navigation Controller is defined in MainWindow.xib
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
So what are the advantages of each approach. Why does apple suggest one approach and yet all its demos use another.
Any thoughts, answers gratefully received.
TIA, Michael.You can do whatever you're comfortable with, but most of the best Cocoa programmers--the ones on the Mac, I mean--recommend putting everything you can into Interface Builder.
It's a little like the difference between writing a program to do a bunch of financial calculations and using a spreadsheet. Yeah, the program can do everything the spreadsheet can--and more besides--but you'll find it far easier to create, use and modify the spreadsheet.
Interface Builder takes away a lot of completely meaningless choices ("What order should I create the objects in? How should I name the variables? How should I create their frames? What order should I set the attributes in?"), leaving you with an interface optimized for creating and arranging objects, and allowing your code to focus on what you really do need to think about--your application's logic.
(By the way--part of the reason Apple's demos don't all use Interface Builder is that the very first SDK releases didn't have it. Back then, you had to create all your views programatically. Believe me, I have no wish to go back to setting autoresize masks manually. Now get off my lawn, whippersnapper.) -

Now I want to use the Vector class, but this code for example:

1046: Type was not found or was not a compile-time constant: Vector.

I can see that I have Flex 3.2 SDK.
Even more than that: When I search for "Vector" in the help ("Adobe® Flex™ 3 Language Reference") I can see all the details about Vector.
What can I do?
I'd like to avoid installing any newer SDKs due to all the bugs I see listed here in the forums.
Thank you!It looks like you are trying to type Java code in Flex Builder. Flex applications are generally built using ActionScript.
These docs might help you learn ActionScript:
