Best way to repaint/refresh JFrame classes.

Hello everyone,
I am developing a small application for my studies. I have several classes many representing a user form allowing interaction with my system.
One of my first class instances is a Menu Screen from which the user can for example update their details. When the Update Details frame is closed by the user I invoke
frameName.setVisible(false);
frameName.dispose();This removes the Update Details frame and the Menu Screen is now fully visible.
However this screen does not get refreshed and remains partially obscured by the background color of the JFrame, even if I bring say a browser to the foreground and then click the original Menu Screen to the foreground it does not refresh the Menu Screen and remains half painted.
I was wondering about a few things.
1. Is there a way of detecting when the current JFrame has just received the focus, at which point I could repaint the screen.
2. Is there a way of Menu Screen discussed above being able to detect the closure of the Update Details JFrame (a separate class) and then take appropriate steps to repaint/refresh itself.
3. Ideally what I would like to do is Hide the Menu Screen then allow the user to interact with their menu selection and then Un-hide the Meun Screen when the user is done interacting with their menu selection.
4. Are there any tutorials on this type of thing, that anynone could direct me to.
Thank you for your consideration.
Cheers

Flex/AS3 Best way to construct a derived class instance from an existing base class instance?

What is the best way to handle the instantiation of a derived class from an existing base class.
I have a base class which is being created via remote_object [RemoteClass alias] from the server.   I have other specialized classes that are derived from this baseclass, but serialization with the server always happens with the base class.     The base class has meta data that defines what the derived class is, for example
[RemoteClass (alias="com.myco...')]
public Class Base
     public var derivedType:String;
     public function Base()
public Class Derived extends Base
     public "some other data"
     public function Derived()
In my Cairgorm command which retrieves this object from ther server I want to do this:
public function result (event: Object):void
    var baseInstance:Base = event.result;
     if (baseInstance.derivedType = "derived")
          var derivedInstance:Derived = new Derived( baseInstance );
What is the most efficient way of doing this?   It appears to me that doing a deep-copy/clone and instantiation of the derived class is pretty inefficient as far as memory allocation and data movement via the copy.

Thanks for the assistance. Let me try to clarify.
MY UI requires a number of composite classes.    The individual components of the composite classes are being transfered to/from the server at different times depending upone which component has changed state.    The construction of the composite classes from the base class happens in my clients business logic.
Composition happens in a derived class; but server syncronization happens using the base class.    When I recieve the object from Blazeds through the remote object event, it is in the form of the base class. I then need to instantiate the derived class and copy the elements of the base class into it (for later composite construction).   And likewise when sending the base class back to the server, I need to upcast the derived class to its base class.   But in this case just a mere upcast does not work. I actually need to create a new base class and copy the attrbutes into it. I believe this is limitation of how remoting works on Flex/AS3.
My question is, what is the best way to turn my base class into it's derived class so further composite construction can take place.   The way I am currently doing it is to create a load method on the base class, that takes the base class as on argument. The load function, copies all of the instance attribute references from the base class to the target class.
public Class Base
     public function Base()
     public function load(fromClass:Base)
    { // copy the references for all of the instance attributes from the fromClass to this class }
Then, after I recieve the base class from the server.   I create a new derived class and pass the base class into the load function like this:
            for (var i:int=0; i < event.result.length; i++) {
                var derived:Derived = new Derived();
                derived.load(event.result[i]);
The drawbacks of this approach is that it now requires 2 extra instance creations per object serialization.   One on recieving the object from the server and one sending it to the server.    I assume copying references are pretty efficient. But, there is probably some GC issues.     The worst of it is in code maintenance.   The load function now has to be manually maintained and kept in sync with the server class.
It would be interesting to hear how others have solved this problem.      The server side is an existing application with around 2M LOC, so changing the code on the server is a non-starter.
Thanks for your help.

Best way to write an Wrapper class around a POJO

Hi guys,
What is the best way to write an Wrapper around a Hibernate POJO, given the latest 2.2 possibilities? The goal is, of course, to map 'regular' Java Bean properties to JavaFX 2 Properties, so that they can be used in GUI.
Thanks!

what about this:
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
public class PersonPropertyWrapper {
     private StringProperty firstName;
     private StringProperty lastName;
     private Person _person;
     public PersonPropertyWrapper(Person person) {
          super();
          this._person = person;
          firstName = new SimpleStringProperty(_person.getFirstName()) {
               @Override
               protected void invalidated() {
                    _person.setFirstName(getValue());
          lastName = new SimpleStringProperty(_person.getLastName()) {
               @Override
               protected void invalidated() {
                    _person.setLastName(getValue());
     public StringProperty firstNameProperty() {
          return firstName;
     public StringProperty lastNameProperty() {
          return lastName;
     public static class Person {
          private String firstName;
          private String lastName;
          public String getFirstName() {
               return firstName;
          public void setFirstName(String firstName) {
               this.firstName = firstName;
          public String getLastName() {
               return lastName;
          public void setLastName(String lastName) {
               this.lastName = lastName;
     public static void main(String[] args) {
          Person p = new Person();
          p.setFirstName("Jim");
          p.setLastName("Green");
          PersonPropertyWrapper wrapper = new PersonPropertyWrapper(p);

Best way to animate refresh arrows

Hi all, I am looking for a best practice for animating two arrows along the path of an O (font: Times new Roman)
See the picture below, it is not as simple of rotating the arrows, as the arrows have to move along a oval path and the paths stroke is not a consistent thickness.
I could animate frame by frame but I figured some guru on here might be able to suggest an expression or some other more optimized way. Thank you in advance for any tips. Chris

A few of the tricky steps I left out:
Change the anchor point of the triangle to be at the "base" with the pan-behind tool
1st arrow:
time-reverse the keyframes.
adjust the rotation and anchor point of the arrow to place it correctly.
set the arrow to "Auto-orient" "orient along path"
2nd arrow:
select mask path again and look at the "first vertex" which is the square vertex--not round.
go to the vertex that is 180 degrees and select it, right click and set first vertex
then repeat above

What's the best way?? Need Master Class POV

I've got material shot with two cameras. The video portion I want to use...the audio I'm using from another source that is better quality (live musical performance).
Somehow, all of this needs to come together in one edited music video.
How do I go about starting such an editing project? We're talking no SMPTE, no code, no sync, no fancy stuff at time of shooting. Just a couple of guys with consumer grade cams shooting a band performance. The audio (DAT recording at the board) I will hot rod in Logic and import in the final product into FCP. I obviously can't import in the finished audio track at this point until I know how the video portion is going to be stirred up and mixed.
How would you guys approach this? I'm in so deep in trying to figure out the proper workflow that my head is about to explode.
Thanks guys.

I would actually take your final audio and lay that portion down into a timeline in FCP and cut based on that - like a music video. (You can always replace that audio later if you are doing some mix in Logic - just a rough is all you need - but make sure the timing is the same if you remix it later - don't add another verse or lose a chorus - unless you can repeat that edit.)
Normally, for something like this, you would use multi-cam - which acts like a switcher between several camera sources. I have only cut multi-cam in AVID - but in AVID you can lock video tracks together that have no timecode - just set in points and it locks from there. Someone else on the forums with better knowledge of the multi-cam in FCP might be able to instruct you.
But, you can do a poor man's multi cam - eye-match all your cameras of the performance to that audio. Maybe put the main camera on V1 and work your way your way up from there. Then all the cameras are in sync and on different layers and then you just select your shots - and pull out what you don't like. Eventually, you would widdle it down to a tight edit.
OR, another option is to just log all the shots you love and the cut it like a music video - you would still eye match any performance shots to get lip sync.

Version Management for classes ; Best way to restore a class and methods

I have a question about the best way to actually restore a class to its previous version.
There is a class that contains about 60 to 80 methods. Now the task it to revert the class back to some previous state.
The desired versions of the class are spread across several transport - so there is no single transport that holds all the right versions.
What is the best and easiest way to proceed from here?
Do we have to revert back each method individually? Or is there a better method?
The desired version are in a another system - having a transport complied in that system does not to seem an option here.
Any tip? Is there any aux. report etc. that might help out?
Thanks for your input,
C.N

Excellent answer - of which I was afraid of. Maybe I can press the matter and get them to initiate a transport of copies from the target system to the source system - which indeed would be the best solution.
But just imagine it is done - the well needed fix applied - what is the best way to revert back to the new version in the source system?
What would the transport of copies do to the transport history?
There seems to be just the manual way...or is it doable to store the current state of the class in a transport having it released but not imported into any other system?
After the fix is applied can that transport be imported back to restore the current version (for which the fix needs to be applied again of course...)
Thanks for you thoughts and input

Best way to Unit Test Controller Layer

Hi, I was hoping to get the opinion on this matter. My group is currently discussing which method would be the best to Unit test the Controller Layer (using StrutsTestCase). Basically with StrutsTestCase, you can test your Action methods and verify that the action forwards to the correct place, or that certain errors come up. The problem is that these Action classes will make Model layer calls that affect the DB. Whats the best way to test the Action classes? Some possibilities are:
#1) Make a mock model layer that instead of hitting the DB uses a "switch" statement to return the correct value.
#2) Use a test DB to test this. The problem with this is that after running tests, you want to leave the test DB in the same state as when you started the test. This is not very easy to do if your web application only does inserts to the DB. In addition, the Model layer Unit testing will be designed such that it will insert, select, update, select, and delete (in that order), so the state of the DB will remain the same after the test is run (unless JUnit crashes halfway).
#3) Use a copy of a test DB on your local computer. This is beneficial because you can do anything to the DB, and then just delete it because a "master" copy is located elsewhere. The problem with this is, we also hoped to do performance testing of the model layer by running multiple threads of the Model layer unit tests. This won't work now because each thread would make a copy of the master DB....
Thanks for any suggestions you might have!
-L

I have never unit tested just a controller. I have always done end to end testing with the systems I have worked on, so I am coming from a different viewpoint than yourself. I would tend to think that just running a full unit test all the way to your database would be the best test. You will be more likely to find the issues with your program if you are testing with an environment as similar to production as possible.
After running a test you can either purge the data you entered from your test by having sql scripts run against the db, or if this is difficult just reload the database from its original backup. You would probably be able to purge the data quicker than reloading the database from my experience, but it depends on your complexity of the sql scripts.
best of luck.

Best way for Database Reorg.

Hi Experts
I want your advise on what is the best way for Database Re-Organizing / Database Refresh.
Regards.

Hi,
what is the best way for Database Re-Organizing?Good question!
Oracle's official way to do online table reorgs is with the dbms_redefinition utility, and here are my notes:
http://www.dba-oracle.com/t_online_table_reorganization.htm
Under the covers, it uses CTAS, which can also be done in parallel:
http://www.dba-oracle.com/t_create_table_select_ctas.htm
Of course, you can also do reorgs with Data Pump . . . .
what is the best way for Database Refresh? I use a fast clone procedure:

JPA -- Best way to refresh a List association?

Hi,
I need to refresh a OneToMany association.
For example, I have two entities: Header & Detail.
@Entity
@Table(name="HEADERS")
public class Header implements Serializable {
    @OneToMany(mappedBy="header")
    private List<Detail> details;
@Entity
@Table(name="DETAILS")
public class Detail implements Serializable {
    @ManyToOne(fetch=FetchType.LAZY)
    @JoinColumn(name="HDR_ID", referencedColumnName="HDR_ID")
    private Header header;
}So, I fetch the Header along with all its Details.
At a later point of time, I know that some Detail rows in the database have been changed behind my back. I need to re-fetch the list of Details. What should I do?
1. I could add a cascade parameter to the @OneToMany association. I could specify:
@OneToMany(mappedBy="header", cascade={CascadeType.REFRESH})Then I could run:
entityManager.refresh(header);The trouble is that, since all the Details are already in the cache, the cached entities will be returned, not the ones fetched from the database. So, I won't refresh a thing. A query will be sent to the database indeed, but I will get the cached (i.e. stale) entities. I don't know of a way to specify something like
setHint(TopLinkQueryHints.REFRESH, HintValues.TRUE)dynamically for associations, so that the values in the cache would be replaced with the ones fetched from the database.
2. I could try to turn off the caching for the while Entity class. The trouble is that for some reason this doesn't work (see my other question here JPA -- How can I turn off the caching for an entity? Besides, even if it worked, I don't want to turn off the caching in general. I simply want to refresh the list sometimes.
Could anyone tell me what's the best way to refresh the association?
Best regards,
Bisser

Hi Chris,
First, let me thank you that you take the time to answer my questions. I really appreciate that. I wish to apologize for my late reply but I wasn't around the PC for a while.
TopLink doesn't refresh an entity based on a view. I will try to explain in more detail. I hope you'll have patience with me because this might be a bit longer even than my previous post. I will oversimplify my actual business case.
Let's assume we have two tables and a view:
create table MASTERS
(id number(18) not null primary key,
   master_name varchar2(50));
create table DETAILS
(id number(18) not null primary key,
   master_id number(18) not null,   -- FK to MASTER.ID
   price number(7,2));
create view DETAILS_VW as
select id, master_id, price
from details;Of course, in real life the view is useful and actually peforms complex aggregate calculations on the details. But at the moment I wish to keep things as simple as possible.
So, I create Entities for the tables and the view. Here are the entities for MASTERS and DETAILS_VW, only the essential stuff (w/o getters, setters, sequence info, etc.):
@Entity
@Table(name="MASTERS")
public class Master {
     @Id
     @Column(name="ID", nullable=false)
     private Long id;
     @Column(name="MASTER_NAME")
     private String masterName;
     @OneToMany(mappedBy="master", fetch=FetchType.LAZY, cascade=CascadeType.REFRESH)
     private List<DetailVw> detailsVw;
@Entity
@Table(name="DETAILS_VW")
public class DetailVw {
     @Id
     @Column(name="ID")
     private Long id;
     @ManyToOne(fetch=FetchType.LAZY)
     @JoinColumn(name="MASTER_ID", referencedColumnName="ID")
     private Master master;
     @Column(name="PRICE")
     private Double price;
}So, now we have the tables and the entities. Let's assume one master row and two detail rows exist:
MASTER: ID=1, MASTER_NAME='Master #1'
DETAIL: ID=1, MASTER_ID=1, PRICE=3
DETAIL: ID=2, MASTER_ID=1, PRICE=8And now let's run the following code:
// List the initial state
Master master = em.find(Master.class, 1L);
List<DetailVw> detailsVw = master.getDetailsVw();
for (DetailVw dv : detailsVw) {
     System.out.println(dv);
// Modify a detail
EntityTransaction tx = em.getTransaction();
tx.begin();
Detail d = em.find(Detail.class, 2L);
d.setPrice(1);
tx.commit();
// Refresh
System.out.println("----------------------------------------");
em.refresh(master);
// List the state AFTER the update
detailsVw = master.getDetailsVw();
for (DetailVw dv : detailsVw) {
     System.out.println(dv);
}And here are some excerpts from the console (only the essentials):
DetailVw: id=1, price=3
DetailVw: id=2, price=8
UPDATE DETAILS SET PRICE = ? WHERE (ID = ?)
     bind => [1, 2]
SELECT ID, MASTER_NAME FROM MASTERS WHERE (ID = ?)
     bind => [1]
SELECT ID, PRICE, MASTER_ID FROM DETAILS_VW WHERE (MASTER_ID = ?)
     bind => [1]
DetailVw: id=1, price=3
DetailVw: id=2, price=8You see, the UPDATE statement changes the DETAILS row. The price was 8, but was changed to 1. I checked the database. It was indeed changed to 1.
Furthermore, due to the refresh operation, a query was run on the view. But as you can see from the console output, the results of the query were completely ignored. The price was 8, and continued to be 8 even after the refresh. I assume it was because of the cache. If I run an explicit query on DETAILS_VW with the hint:
q.setHint(TopLinkQueryHints.REFRESH, HintValues.TRUE);then I see the real updated values. But if I only refresh with em.refresh(master), then the DetailVw entities do not get refreshed, even though a query against the database is run. I have tested this both in JavaSE and in OC4J. The results are the same.
An explicit refresh on a particular DetailVw entity works, though:
DetailVw dvw = em.find(DetailVw.class, 2L);
em.refresh(dvw);
System.out.println(dvw);Then the console says:
DetailVw: id=2, price=1So, the price is indeed 1, not 8.
If you can explain that to me, I will be really thankful!

Bisser

Best way to refresh page after returning from task flow?

Hello -
(Using jdev 11g release 1)
What is the best way to refresh data in a page after navigating to and returning from a task flow with an isolated data control scope where that data is changed and commited to the database?
I have 2 bounded task flows: list-records-tf and edit-record-tf
Both use page fragments
list-records-tf has a list.jsff fragment and a task flow call to edit-record-tf
The list.jsff page has a table of records that a user can click on and a button which, when pressed, will pass control to the edit-record-tf call. (There are also set property listeners on the button to set values in the request that are used as parameters to edit-record-tf.)
The edit-record-tf always begins a new transaction and does not share data controls with the calling task flow. It consists of an application module call to set up the model according to the parameters passed in (edit record X or create new record Y or...etc.), a page fragment with a form to allow users to edit the record, and 2 different task flow returns for saving/cancelling the transaction.
Back to the question - when I change a record in the edit page, the changes do not show up on the list page until I requery the data set. What is the best way to get the list page to refresh itself automatically upon return from the edit-record-tf?
(If I ran the edit task flow in a popup dialog I could just use the return listener on the command component that launched the popup. But I don't want to run this in a dialog.)
Thank you for reading my question.

What if you have the bean which has refresh method as TF param? Call that method after you save the data. or use contextual event.

What is the best way to deploy/update custom security realm classes to WLS 6.0?

From the WLS 6.0 console, I see that I can specify the Java class that
implements my custom security realm but I am wondering what is the best way
to deploy/update this code. I don't see a way to do this from the console.
Does this mean that I have to manually copy the class files over that
implement my custom security realm?

Thanks Danut,
A jar file seems to be a good way to package it up but it sounds like it
still needs to be manually copied to each Weblogic server install directory
post-installation and whenever it is updated. I thought it would be nice to
be able to deploy/update the custom security realm by uploading it through
the Console just as you can with web applications and EJBs.

You have to have your Custom Realm class in the class path. I usually havea

folder. Then I modify "startWebLogic.cmd" and I add to the classpath
".\lib\CustomRealm.jar"
set

Be aware that in order to have you custom realm besides creating thecustom

that one as your default caching realm.
Here is how the security settings are looking in my "config.xml"

<CachingRealm BasicRealm="CustomRealm" CacheCaseSensitive="true"

Best way to get SharePoint workflow to trigger InDesign XML refresh and PDF export?

What is the best way to get a SharePoint workflow to trigger the refresh of an XML datasource within an InDesign document, and generate a PDF export? The datasource would be hosted by SharePoint.
Would InDesign Server be required?

My understanding of the license is that Adobe requires you to use InDesign Server for this sort of thing.
But the implementation is probably the same either way. Periodically poll, or find some way to trigger it.

The best way to change BO layer (in B2B Java class)

Hi, mate:
One question, what is the best way to modify a business object.
For example: in B2B java, there is a class:
BidMgrImpl.java, however I want to modify some code for method Bid(),and for the action flow and JSP, I do not need to modify them.
I am looking for the simpliest way to implement this. instead of modify from JSP, to config.xml, action, and BidMgrImpl.java?
Cheers,
Eric

Hi, Prashil:
Thanks for your reply.
And a basic question, I am using NWDS now, and have none exprience of the tool.
I followed one PDF file(How_To_Create_Custom_App_ECO5200.pdf) to create my application(b2b_xyz), now I have three applications:
- LPJ_CRM_Db2b_xyzsap.com
- LPJ_CRM_Dcrmhomeshrext~sap.com
- LPJ_CRM_Dcrmisawebb2b~sap.com (this contains all JSP files under webcontent folder).
my question is if I need extend one class, where and how can I create:
for example in SAP application:
com.sap.isa.auction.businessobject.b2x.BidMgrImpl
In this class, if I need extend, what's gonna be the classpath, and where I can create this subclass.
Cheers,

Best way to use library movieclips with classes?

Hi,
I've created a carousel class which takes one parameter, an array of menu item names, these will then be displayed on the carousel. I've then created two movieclips for the left and right controls, added them to the library and given them classes of their own.
Within the carousel class I instantiate instances of the two control classes which then enables me to add event listeners for rollover and rollout.
What I'd like to know is, is this the best way to do this short of creating the controls using pure actionscript?
I'd like to not have to add the class properties for the left and right controls and have a situation where I could just give them the right name and they would work or maybe pass them in as parameters and use them that way.
Any tips for how you would go about doing this would be much appreciated.
Thanks,
eb_dev

Have you tried something that isn't working? If I understand what your intentions are, I would think that the approach would be to create Class ID's for the clips and import the classes into the carousel class.
