Need package help
I've got three files in a package. In the .java file with the main method, I've tried putting the package statement at the top, and import statements, but I still get errors in my main method that are unresolved symbols referring to the classes in the other two files. How is this done exactly?
All of my .java files are in H:\wired
All .java files (including main) have package wired; at the top
I import wired.*; in my main file (tried this with and without it)
Nothing works so far. If you need more info about the code, please refer to my "Need help moving to OO" thread below.
If you want your classes to be in package "wired" then you put "package wired;" as the first line of code. So far so good.
You don't need to import anything to use classes in the same package, so "import wired.*;" is unnecessary.
If your .java files are in H:\wired, then you must make sure that H:\ is in your classpath. Not H:\wired. The package has to be in the classpath. You may be able to achieve this just by changing your current directory to H:\, but I'm not going to say any more about how to set your classpath.
And if you want to compile "magazine.java" from that package, you need to type "javac wired/magazine.java" at the command line.

Need your help on performance issue please
Hello everyone!
I need your help to understand an effect I notice with a Thread class I built. I currently work on enhancement of my application Playlist Editor (see http://www.lightdev.com/page74.htm) and a new release will be available soon.
Among other extensions the new release will have a title filter function which is based on audio data that is recursively read from ID3 tags of files found in a given root directory. The data collection is done by a CollectionThread class which reads into a data model class AudioDataModel and the entire process works fine, no problem with that.
However, when my application is started for the first time the CollectionThread runs approximately 3 minutes to collect data from approximately 4300 audio files on an Intel Pentium M 1,4 GHz, 512 MB RAM, Windows XP SP2. When the application is shut down and started again, it takes only a few seconds to do the same task for all subsequent launches.
I already tried to start the application with java option -Xms40m to increase initial heap size. This increases performance in general but the effect is still the same, i.e. first run lasts significantly longer than subsequent runs.
I also tried to build a pool mechanism which creates many empty objects in the data model and then releases them to contain the actual data at is being read in but this did not lead to better performance.
It must have to do with how Java (or Windows?) allocates and caches memory. I wonder whether there is a way to pre-allocate memory or if there are any other ideas to improve performance so that the process always only takes seconds instead of minutes?
I attach the key classes to this message. Any help or ideas is much appreciated!
Thanks a lot a best regards
Ulrich
PS: You can use the news subscription service at
http://www.lightdev.com/dynTemplate.php4?id=80&dynPage=subscribe.php4 to be informed when the new release of Playlist Editor is available.
All classes posted here do not need debugging, they already have proven to run error free. The classes are only posted for information for the interested reader - no need to go through all the stuff in detail - only if it interests you.
My application calls class CollectionThread wich is a subclass of InfoThread. CollectionThread recursively goes through a directory and file structure and stores found ID3 tag information in instances of class ID3v11Tag which in turn gets stored in one instance of class AudioDataModel. All classes are shown below.
This is the mentioned CollectionThread

*Hi Franck,
thank you, mate. I did what you suggested (changed class attached) but that did not change the mentioned behaviour.
The first run is approximately 75 seconds with Java option -Xms40m and approx. double without, the second run and all subsequent runs are only 2-3 seconds each (!!!) even when terminating and re-starting the application between thread runs.
I'm pretty clueless about that, any more help on this anyone?
Thanks a lot and best regards
Ulrich

I need Fusion help creating a demo of BRM JCA Resource Adapter
I need Fusion help creating a demo of BRM JCA Resource Adapter.
I know BRM well but am clueless with Fusion.
I am trying to figure out what Fusion products to download and install and how I manipulate the Fusion side to manipulate BRM.
My BRM docs say:
Installing the BRM JCA Resource Adapter ->
Software requirements
(yada yada install a bunch of BRM stuff I know how to do)
The adapter must be deployed on a J2EE 1.4-compliant application server that has implemented the JCA 1.5 specification. The adapter runs only in a managed environment. (Does this imply some particular Fusion package?)
(more yada yada about installing more BRM packages I know how to do)
Deploying and configuring the BRM JCA Resource Adapter ->
Overview of the BRM JCA Resource Adapter configuration procedure
The procedure for setting up the BRM JCA Resource Adapter includes the following tasks:
Installing the adapter on your BRM system, if you have not already done so. See Installing the BRM JCA Resource Adapter.
Generating the schema files for the adapter. See Generating the schema files for your system. (links to some BRM commands np)
Specifying how to construct XML tags. See Specifying the XML tags for extended fields. (links to an oob file included with directions on how to address BRM customizations np)
Generating the WSDL files for the adapter. See Generating the WSDL files for your system. (links to an oob file with directions to configure. I could use some help if/when I get this far)
The last two look pretty important but I haven't a clue. I pasted the text from the docs below.
Deploying the adapter on your application server. See Deploying the BRM JCA Resource Adapter on an Oracle application server.
Connecting the adapter to the BRM software. See Connecting the adapter to BRM in Oracle AS.
Deploying the BRM JCA Resource Adapter on an Oracle application server
The adapter is dependent on Java Archive (JAR) files to deploy properly. The following table lists the JAR files that the adapter requires from each application in your system.
Application
JAR files
J2EE application server
classes12.jar, connector15.jar, and jta.jar
Oracle BPEL process
bpm-infra.jar, orabpel-thirdparty.jar, orabpel.jar, and xmlparserv2.jar
BRM J2EE Resource Adapter
pcm.jar and pcmext.jar
Apache
xercesImpl.jar
If you are deploying the adapter in a standalone Oracle Containers for Java EE (OC4J) instance, make sure these JAR files are available to the class loader that is loading the adapter.
If you are deploying the adapter by using Oracle SOA Suite, these JAR files are available as part of the oracle.bpel.common code source. You import these libraries as follows:
Open the Oracle_home/j2ee/Instance/config/applications.xml configuration file for the J2EE instance.
Add the oracle.bpel.common entry (shown in bold below) to the imported-shared-libraries section of the file:
<imported-shared-libraries>
<import-shared-library name="adf.oracle.domain"/>
<import-shared-library name="oracle.bpel.common"/>
</imported-shared-libraries>
Save and close the file.
Restart the application server or the J2EE instance.
After you make the JAR files available, deploy the adapter on the Oracle application server by using either the Oracle Application Server (Oracle AS) Application Server Control (ASC) or the Oracle admintool.jar file. Copy the adapter archive file (BRM_home/apps/brm_integrations/jca_adapter/OracleBRMJCA15Adapter.rar) from the installation directory to a location that is accessible to the adapter deployment tool. You can then open and deploy the archive file on your application server.
After successful deployment, return the applications.xml file to its original settings and add the oracle.bpel.common codesource to the BRM Adapter oc4j-ra.xml file:
Open the Oracle_home/j2ee/Instance/config/applications.xml configuration file for the J2EE instance.
Remove the following oracle.bpel.common entry (shown in bold below):
<imported-shared-libraries>
<import-shared-library name="adf.oracle.domain"/>
<import-shared-library name="oracle.bpel.common"/>
</imported-shared-libraries>
Save and close the file.
Open the JCA Resource Adapter oc4j-ra.xml file from the Oracle_home/j2ee/Instance/application-deployments/default/BRMAdapterDeploymentName directory.
Add the oracle.bpel.common entry (shown in bold below) to the oc4j-connector-factories section of the file:
<oc4j-connector-factories...>
<imported-shared-libraries>
<import-shared-library name="oracle.bpel.common"/>
</imported-shared-libraries>
<oc4j-connector-factories>
Save and close the file.
Restart the application server or the J2EE instance.
For more information about deploying the adapter, see your application server’s documentation.
Connecting the adapter to BRM in Oracle AS
You connect the adapter to the BRM software by creating connection pools and connection factories. As part of the adapter deployment, the application server creates oc4j-ra.xml from the packaged ra.xml. The ra.xml file is located in the Oracle_home/j2ee/Instance/connectors/AdapterDeploymentName/AdapterDeploymentName/META-INF directory. For example, Oracle_home/j2ee/home/connectors/BRMAdapter/BRMAdapter/META-INF/ra.xml.
Use the resource adapter home page from the Oracle AS ASC page to create connection pools and connection factories.
Create your connection pool by following the performance and tuning guidelines in Configuring Connection Pooling in OC4J in Oracle Containers for J2EE Resource Adapter Administrator's Guide. See download.oracle.com/docs/cd/B31017_01/web.1013/b28956/conncont.htm.
Make sure you set the pool’s Maximum Connections parameter (maxConnections XML entity) equal to or greater than the Oracle BPEL process manager’s dspMaxThreads parameter. For more information, see Oracle BPEL Process Manager Performance Tuning in Oracle Application Server Performance Guide for 10g Release 3 (10.1.3.1.0) at download.oracle.com/docs/cd/B31017_01/core.1013/b28942/tuning_bpel.htm.
Note To set up JCA Resource Adapter transaction management in BPEL, you must create a private connection pool and set its Inactive Connection Timeout property (inactivity-timeout XML entity) to 0. See About JCA Resource Adapter transaction management in BPEL for more information.
Create as many connection factories as your system needs. For each connection factory, specify the following:
The JNDI location for the connection factory.
The connection pool to use.

Anybody who can help me? I really need your help
I've tried to execute J2ee tutorial examples.
I don't know why this sample didn't execute...I've already finished to set up J2EE and enviornment variables.
I was trying this part from j2ee tutorial titled as "Packing Web modules".
Whenever I type "asant create-war" to make web modules in command window. I always got error.
Packaging Web Modules(From J2ee tutorial for your information)
A web module must be packaged into a WAR in certain deployment scenarios and whenever you want to distribute the web module. You package a web module into a WAR using the Application Server deploytool utility, by executing the jar command in a directory laid out in the format of a web module, or by using the asant utility. This tutorial allows you to use use either the first or the third approach. To build the hello1 application, follow these steps:
In a terminal window, go to <INSTALL>/j2eetutorial14/examples/web/hello1/.
Run asant build. This target will spawn any necessary compilations and will copy files to the <INSTALL>/j2eetutorial14/examples/web/hello1/build/ directory.
To package the application into a WAR named hello1.war using asant, use the following command:
asant create-war
This command uses web.xml and sun-web.xml files in the <INSTALL>/j2eetutorial14/examples/web/hello1 directory.
To learn how to configure this web application, package the application using deploytool by following these steps:
Start deploytool.
Create a web application called hello1 by running the New Web Component wizard. Select FileNewWeb Component.
In the New Web Component wizard:
Select the Create New Stand-Alone WAR Module radio button.

Thank you in advance.ok,
First of all make sure your tutorial folder is installed from the root:
C:\javaeetutorial5
or
D:\javaeetutorial5
it makes things so simple.
Secondly:
set your jee tutorial home
JAVAEE.TUTORIAL.HOME =
C:/javaeetutorial5
Thirdly: check in:
C:\javaeetutorial5\examples\bp-project
make a copy of the build.properties.sample save it as build.propropties, as a property file,
edit the properties file as in:
build.properties
As follows:
# uncomment the property javaee.home, and add the path
# to your GlassFish Java EE 5 SDK installation
javaee.home=c:/Sun/SDK
javaee.tutorial.home=c:/javaeetutorial5
# Uncomment the property j2ee.server.username,
# and replace the administrator username of the app-server
javaee.server.username=admin
# Uncomment the property j2ee.server.passwordfile,
# and replace the following line to point to a file that
# contains the admin password for your app-server.
# The file should contain the password in the following line:
AS_ADMIN_PASSWORD=admin1234and so fourth. Some of the settings as the application server name is all done for you
and then test it again.
Take care of editing the property file. It can give you headache.
Note also that this is for application server 9.1 - JEE5.

Please I need some help with a table
Hi All
I need some help with a table.
My table needs to hold prices that the user can update.
Also has a total of the column.
my question is if the user adds in a new price how can i pick up the value they have just entered and then add it to the total which will be the last row in the table?
I have a loop that gets all the values of the column, so I can get the total but it is when the user adds in a new value that I need some help with.
I have tried using but as I need to set the toal with something like total
totalTable.setValueAt(total, totalTable.getRowCount()-1,1); I end up with an infinite loop.
Can any one please advise on some way I can get this to work ?
Thanks for reading

Need urgent help in listing out checklist from DBA prespective for BI Implementation Project
Hello Guys,
We are in Designing phase Data Modeling of PDW/APS Implementation Project.
I need urgent help in making a checklist from a DBA perspective.
Like what are things ill be needing at a time of implementation/Deployment.
Your expert comments and help will be highly appreciated.
Thank you,
Anish.S
AsandeenYou can get good summary of checklist from this article about
DBA checklist for data warehousing.
Which highlights on below pointers:
New system or old. (I.e. Up-gradation vs starting from scratch)
Complexity of SQL Server architecture
SQL Server storage
Determining SQL Server processing power
SQL Server installation consideration
SQL Server configuration parameter
SQL Server security
SQL Server Database property
SQL Server jobs and automation
Protecting SQL Server data
SQL Server health monitoring and check ups
SQL Server ownership and control
based on my real time experience, I will suggest you to keep an eye on
Load performance (It will be useful when your database(Warehouse) will have huge amount of data)
System availability (Check for Windows update and up time configuration)
Deployment methodology should be planned in advance. Development of packages and respective objects should be done systematically.
Source control mechanism
Disk space and memory usage
You might or might not have full rights on production environment, so be prepared to analyze production environment via Select statements [I guess you got my point]
Proper implementation of Landing , Staging and Mart tables.
Column size (this can drastically decrease your database size)
Usage of indexes (Index are good, but at what cost?)
I hope this will assist you in building your check list. -
Need some help with threads...
Hello all,
I am working on a project at work, and I am not the best programmer in the world. I have been trying to get my head around this for a couple of days and just cannot get it to work.
I am writing an instrumentation control program that will have three threads. One is the GUI, one will receive control information and set up the hardware, and one will check the hardware status and report it to the GUI periodically. I plan on using the invokeLater() method to communicate the status to the GUI and change the status display in the GUI. Communication from the GUI to the controller thread and from the status thread to the controller thread I had planned on being piped input/output stream as appropriate. I have a control class and a status class that need to be communicated over these piped streams. In some trial code I have been unable to wrap the piped input/output streams with object input/output streams. I really need some help with this. Here is the main thread code:
package playingwiththreads1;
import java.io.*;*
*public class PlayingWithThreads1 {*
public static void main(String[] args) {*
* PipedOutputStream outputPipe = new PipedOutputStream();*
* ObjectOutputStream oos = null;*
* ReceiverThread rt = new ReceiverThread(outputPipe);*
// Start the thread -- First try*
* Thread t = new Thread(rt);*
t.start();*
// Wrap the output pipe with an ObjectOutputStream*
try*
oos = new ObjectOutputStream(outputPipe);*
catch (IOException e)*
System.out.println(e);*
// Start the thread -- Second try*
//Thread t = new Thread(rt);*
//t.start();*
/** Send an object over the pipe. In reality this object will be a
class that contains control or status information */
try
if (!oos.equals(null))
oos.writeObject(new String ("Test"));
catch (IOException e)
try
Thread.sleep(5000);
catch (InterruptedException e)
I read somewhere that it matters where you start the thread relative to where you wrap piped streams with the object streams. So, I tried the two places I felt were obvious to start the thread. These are noted in the comments. Here is the code for the thread.
package playingwiththreads1;
import java.io.*;
public class ReceiverThread implements Runnable {
private PipedInputStream inputPipe = new PipedInputStream();
private ObjectInputStream inputObject;
ReceiverThread (PipedOutputStream outputPipe)
System.out.println("Thread initialization - start");
try
inputPipe.connect(outputPipe);
inputObject = new ObjectInputStream(inputPipe);
catch (IOException e)
System.out.println(e);
System.out.println("Thread initialization - complete");
public void run()
System.out.println("Thread started");
try
if (inputObject.available() > 0)
System.out.println(inputObject.read());
catch (IOException e)
System.out.println(e);
Through testing I have determined that no matter where I start the thread, the thread never gets past the "inputObject = new ObjectInputStream(inputPipe);" assignment.
Could someone please help me with this? There are other ways for me to write this program, but this is the one that I would like to make work.
Many thanks in advance,
Rob Hix
Edited by: RobertHix on Oct 6, 2009 3:54 AMThanks for the help, but that did not work. I tried flushing the ObjectOutputStream and it is still hanging when initializing the thread.
Here is a better look at the code since I was helped to figure out how to insert it:
The main method:
package playingwiththreads1;
import java.io.*;
public class PlayingWithThreads1 {
public static void main(String[] args) {
PipedOutputStream outputPipe = new PipedOutputStream();
ObjectOutputStream oos = null;
ReceiverThread rt = new ReceiverThread(outputPipe);
// Start the thread -- First try
//Thread t = new Thread(rt);
//t.start();
// Wrap the output pipe with an ObjectOutputStream
try
oos = new ObjectOutputStream(outputPipe);
oos.flush();
catch (IOException e)
System.out.println(e);
// Start the thread -- Second try
Thread t = new Thread(rt);
t.start();
/* Send an object over the pipe. In reality this object will be a
* class that contains control or status information */
try
if (!oos.equals(null))
oos.writeObject(new String ("Test"));
oos.flush();
catch (IOException e)
System.out.pringln(e);
try
Thread.sleep(5000);
catch (InterruptedException e)
}The thread code:
package playingwiththreads1;
import java.io.*;
public class ReceiverThread implements Runnable {
private PipedInputStream inputPipe = new PipedInputStream();
private ObjectInputStream inputObject;
ReceiverThread (PipedOutputStream outputPipe)
System.out.println("Thread initialization - start");
try
inputPipe.connect(outputPipe);
inputObject = new ObjectInputStream(inputPipe);
catch (IOException e)
System.out.println(e);
System.out.println("Thread initialization - complete");
public void run()
System.out.println("Thread started");
try
if (inputObject.available() > 0)
System.out.println(inputObject.read());
catch (IOException e)
System.out.println(e);
}Does anyone else have and ideas? -
Meric -- Another package helper (packer fork)
Hi. Here is Meric. I have made modifications to famous and well written "packer" (thanks to Matthew Bruenig) to fit my needs. So a packer fork "Meric" has born. I decided to share it with community. But remember, i am neither a coder nor a bash expert. So, my modifications may be an ugly hack to packer; but it just works for me. I hope you'll enjoy it. All credits must go Mr. Bruening.
From Meric README:
Meric is a package helper for Arch Linux. It can retrieve packages from official repositories and Arch User Repository (a.k.a. AUR).
Meric is a fork of famous "packer" which is developed by Matthew Bruenig <[email protected]>
Meric is born from the needs of the autor.
Meric has a few differences from packer:
1- Meric has a config file. Users may use it for daily meric tasks instead of using options in commandline. Also makepkg options can be set there. Once options have been set; meric can call makepkg with these options by default.
2- Meric has the ability of remove installed dependencies after package creation. Like "makepkg -r". Not perfect but it works for my needs.
3- Meric can skip checking and installing from specified repositories with "--skip-repo" option. This is useful when you setup your custom repository with AUR packages. Aur helpers, including packer, won't treat those packages as aur packages because it thouhgt that they came from a repo (your custom repo). So those packages always skipped when AUR updates checking phase. This option prevents this for you.( also can be set in meric.conf to make it default behaviour)
4- Meric can use translations. For the sake of keep package and its dependencies minimal; only one text file (in bash script format) is used to hold and provide all translations. See TRANSLATIONS section.
5- Meric can call pacman with a custom pacman.conf file for all pacman related operations. Just place your custom pacman.conf under $HOME/.config/meric/ directory.

MAKEPKGOPTS= is different. Possible bug?
Its the only place where the variable gets set.
234c322
< echo "${PKGURL}$(jshon -Q -e results -e URLPath -u < "$tmpdir/$1.info")"
> echo "${PKGURL}$(jshon -e results -e URLPath -u < "$tmpdir/$1.info")"
-Q option
Thank you for interesting in. MAKEPKGOPTS is indeed different and it is not a bug but a feature to allow use of Makepkg options from meric.conf
But you' re right. Somehow i missed -Q option in pkglink function. Will update git with this. Thanks for your feedback! -

Well, these are list of problems with my 9630 Tour, and I need some helps to solve these :
1. My 1st problem is, everytime my 9630 started its also a message appears : "uncaught exception index 8 >= 8"
2. And I also realized that some missing application happened. My m-Banking application (already re-installed well) but it also lost of SMS icon. So the result is, everytime I sent an outgoing SMS I couldn't save it. And I have made a test to sent SMS from my other number to this 9630 device, but 9630 couldn't show that any incoming message, even my other device has given me notification that message has been delivered.
3. Its also often shutdown suddenly by itself, or its shutdown upon charging
4. Charging tasks sometime couldn't be well charged. And finally I realized that my device has off in the middle of charging task, it may caused of charging wasn't recharge the device very well
Hopefully I can read your kindly solution on those problems happened. Thank you for your prompt response.
Anwar HusseinHi and Welcome to the Community!
I actually think that all of your issues are related, and rooted in the same problem...OS corruption or hardware failure. But, before you begin, please be sure you have a good backup...see the link in my auto-sig on this post for instructions for that process.
Then, at the top of each device forum, there should be some "sticky" threads that discuss the OS levels available for many models. If they include your model, then please use those as reference as you proceed. Otherwise, you will have to dig through the official download portal for OS packages for your model:
http://us.blackberry.com/support/downloads/download_sites.jsp
From a PC, you can install any compatible (e.g., for your exact BB Model Number) OS package to a BB via this procedure:
http://supportforums.blackberry.com/t5/BlackBerry-Device-Software/How-To-Reload-Your-Operating-Syste...
Note that while written for "reload" and the Storm, it can be used to upgrade, downgrade, or reload any BB device model -- it all depends on the OS package you download and install to your PC. If that OS package is from a carrier other than the carrier for which your BB was originally manufactured, then delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:
C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML
Be sure that you remove, from your PC, any other BB device OS packages as having more than one installed to the PC can cause conflicts with this procedure.
You may also want to investigate the use of BBSAK (bbsak.org) to perform the wipe it is capable of.
You may also want to try this procedure to perhaps narrow down the precise causal item:
Load your OS "bare bones"...if anything is optional, do not install it.
If the behavior presents immediately, then try a different OS with step 1
If the behavior does not immediately present, then run for as long as it takes for you to be sure that the behavior will not present.
Add one thing -- no matter how tempting, just one.
If the behavior does not present immediately, then again run for long enough to be sure it will not have the same problem
Repeat steps 4 and 5 until all things are loaded or the behavior presents
When the behavior presents, you know the culprit...the last thing you loaded.
If the behavior does not re-present, then you know that either step 1 or 2 cured it.
If the behavior presents no matter what, then you likely have a hardware level issue for which no amount of OS or software can cure.
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:

Upload support package " help"
Hi Expert!! how are you....
i need you help, I will apply support package resouce human, but before making the upload in sap requires decompress in cmd with the command "SAPCAR -xvf Filename extract" since the directory usr/sap/trans/eps/in, but when I write I said "'SAPCAR' is not recognized as an internal or external command,operable program or batch file." It will be something that I am jumping? Some point an area not? I will have to call some command before?
thankHola Luis,
el directorio sapmnt es usualment un share creado para compartir la carpeta \usr\sap asi que si esta apuntando a \sapmnt\eps\in debe haber un path \usr\sap\eps\in.... chequea que el paquete este en esa carpeta...
de lo contrario si es un solo paquete el que vas a cargar en el systema ve a SPAM-> Support package ->Load -> From frontend y apunta a la direccion del SAR file... sap lo descomprimira automaticamente.
Saludos

Bt infinity way to slow !!! Need some help
We just got bt infinity 1 installed with home hub 5 as well, I did a speed test and it was only getting 10mbps download, 5 Mbps upload and 85 ping, is this good or bad. We currently have 10 devices connected to internet in this house, I can't even watch normal you tube videos in 480p, this is annoying as paid a lot of money for it, I know the problem can rely down to the amount I people connected, it may be also down to where the router is ? Need some help to how we can get best performance and how to share the connection between all of us or how to get more as on the best package available ? Thanks will need all the help as the internet is atrocious right now, almost as bad as our non infinity by home hub 2 we had a few days ago
Can you run this checker and post back a screen shot of the results
http://www.dslchecker.bt.com/adsl/adslchecker.welcome
and use this speed tester then carry out the further diagnostics and post back a screen shot of all the results including your IP profile for up and down. This test must be done with a wired connection.

As you have a Homehub 5 can you also post the stats from 1-12 by logging onto the homehub management pages then troubleshooting > helpdesk. http://bthomehub.home/ -
Need some help learning cue points, etc
I need some help with a Flash project I'm working on. If any
Flash junkies out there are up for sitting down with me through
email or IM and helping me get to the point where I have a template
FLA doing what I want to do, I'd be willing to pay you. It wouldn't
be much, but it would be something. Here's what I'm trying to do:
I need to create an interactive talking-head style flash
presentation with a number of progressive download externally
linked FLV files, playing in succession, supported by movie-clip
text animations and supporting graphics which are triggered by cue
points in the video. I also need a simple navigation menu linking
to the FLV files. I've got some of this down already, namely, I've
laid the FLVs in and they are playing in succession. I'm stuck on
the cue point part. At this point I really just need some hands-on
help. I've bought books, I've scoured the web.
I'm easy to communicate with, and I'm good with computers and
comfortable in many multimedia design programs. Flash is very
powerful, but tougher to learn than I expected, and I'm at the end
of my rope =PMy advice... start with a very simple "proof of concept" project before you attempt the entire package.
It will be much easier to scale up if you first have a very good understanding of what's going on.
So one simple video with just one cuepoint and only one button and additional display. You'll also have to work out the interaction of pausing the video when a cuepoint is reached or button pushed to display the graph, giving the viewer time to read the graph... then when the viewer closes the graph, the video should "resume".
Start very simple and build on that only after you understand the fundamentals.
Second, you mention "video reports"... plural. So that most likely means that you will need a video player with a "playlist".
This may mean that you'll need to learn to use a little .xml to bring in the playlist data. You may also find xml an excellant way to bring other data into you project.
At the link listed above there is an excellant tutorial on "Integrating Flash and XML"
"Flash and XML"
"XML Video Playlist"
"ActionScript 3 XML Basics"
"ActionScript 3 Advanced XML"
Personally I would not even begin a project like this without considering how I could use xml to feed data into the project.
Here's an example of a video player I created that has a playlist, thumbnails, categories, transcipts, "Now Playing" etc. All that data comes into the main .swf via various xml files. Super good way in input data into Flash.
http://www.drheimer.com/video/
Yours is a rather ambitious project and will take awhile to gain the skill and assemble the pieces. So when you come to a new part... first create a real simple "proof of concept" model so you can learn how that section works. Don't expect to be able to assemble the entire project all at once.
Best wishes,

I got my artwork and saved it to my Desktop
Opened up Microsoft Paint and clicked on "File" and "Open" and found it to get it on the screen to resize it
Clicked "resize" and a box for changing it opened up
Checked the box "Pixels" and "Unchecked maintain aspect ratio"
Set Horizontal for 640 and Vertical for 480
Clicked on "OK" and went back to "File" and did a "Save As" and chose JPEG Picture
It came up "File Already Existed" and clicked "OK" (really did not care about the original artwork I found because wrong size)
Went to iTunes and on the movie right clicked on "Get Info", clicked on "Details", then "Artwork"
Go to the little box on the top left that shows your old artwork and click on it to get the little blue border to appear around it and hit "Delete" to make it gone
Click on "Add Artwork" and find it where you put the one from above on your Desktop and hit "Open" and OK and your new artwork is now there and all good.
Sounds like a lot of steps to follow but after around 5 or so you will fly through it. This worked perfect on my iPhone 6 Plus and I have artwork on my Home Videos now. -
Need your help in Remodeling concept
Hi Gurus need your help in time estimations
I have a cube with data and now I need to add 10 new info objects to the cube which are including Date fields (BUDAT, BLDAT) these 10 fields will be populated to the cube from a Z table in ECC as we donu2019t have these fields in the cube we have to go for remodeling of the cube
My client requires how much time it will take to complete this
Now I want to know how much time it would take to do this (if any customer exits and user exits are required) and addition if new fields will have any effect on the current queries
Please advice in this
Thank youThe time taken will depends on a lots of factor like server speed, available memory, background jobs etc. Apart from this, the time will also depends on how much the cube is filled i.e. the no. of records in the cube. Its very abstract to tell you the exact time taken for this. But, please make sure that you have the backup of the cube which you are going to re-model. T0 say, I think 3-4 hours should be ok for the remodelling.
Thanks.
