Question about blazeds turnkey, tomcat and directory structure

hi. this question is pretty basic...been reading sujit reddy g's blog on installing/setting up blazeds.
in one article he creates a samplewebapps directory in C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\samplewebapps and copies the blazeds WEB-INF/lib into that directory and the configuration files in the flex folder across as well...http://sujitreddyg.wordpress.com/2009/04/07/setting-up-blazeds/
in another article on invoking java methods from flex he configures the remote-config.xml file directly in the blazeds\WEB-INF\flex folder....http://sujitreddyg.wordpress.com/2008/01/14/invoking-java-methods-from-adobe-fle x/
wasn't sure why in the first example he copied the files and folders to the samplewebapps directory while in the second example he just configured the files within the blazeds directory...thanx...(i'm a newbie at server side development)

I'll take a stab at it. The key thing to realize is the BlazeDS code is ADDED on
to the appserver. E.g. for Tomcat/WebLogic/et al one adds the reference in the web.xml file in WEB-INF.
So, what is that add-on?
1. Executable files. These are jar files and typically stuck into WEB-INF/lib
2. Configuration files. flex/services-config.xml is specified in web.xml. It refers to the other config files in WEB-INF/flex
So, the config in web.xml tells Tomcat (and its forked commercial products) to load up the Flex jars and run some classes. By standard, the "run some classes" follows the servlet lifecycle and runs specific methods in the class when the servlet is loaded, called, destroyed. So, Flex jars have a class which implements the servlet interface.
Incidentally, you may also see references to log4j, Spring, and other frameworks in the web.xml as well. They do the same sort of stuff. So, Tomcat does the passing of the HTTP packets and stages them into Java classes and the hooked in frameworks do add their own behaviours to the setup.
HTH,
TimJowers
P.S> Also note in Flex when you setup the project properties for a Flex Project then you need to match up your URL and "context" to what you have on your server. In his exampe, the "samples" context may have already been setup so easier to use. What is a "context"? The idea is to have more than one webapp running on an appserver. In Tomcat, its basically just the subdirectory under "webapps". That directory name becomes part of the URL. E.g. webapps/samples -> http://localhost:8080/samples or webapps/mytest -> http://localhost:8080/mytest

There's really not much difference. In some cases, you might already have a web application you are using so you could just copy the contents of the blazeds web app into your existing web application.
Application servers can host more than one web application and a Flex application that uses BlazeDS can be deployed on a different web app than the one where BlazeDS is running or a different server entirely so it really just depends how you want to set things up.
Hope I'm not just making things more confusing for you. . .

Package and Directory Structure

Hello --
I work in a group that supports 3 web sites. (b2b, b2c, b2e)
We're just beginning to develop Java in-house and
currently using Solaris and JDK 1.2.x.
I need to propose a package and directory structure strategy.
The "reverse the domain name" guideline makes sense to me.
My first thoughts are: ("classes" dir could be created anywhere)
classes/com/ppco/b2X/ <--- for .java and .class files (development)
lib/ <--- for b2X JAR files (ready for test or production)
util/ <--- for our utility classes like DBAccessor
lib/ <--- for our JAR files
sun/ <--- for classes like com.sun.mail pkg
lib/ <--- for JAR files like mail.jar
org/ <--- for classes in org.omg.CORBA pkg
lib/ <--- for JAR files
We need to handle 3rd party classes.
Development would be done in the b2X tree and JAR files would
be installed the lib/ dir for testing and release to production.
Does anyone have recommendations or experiences to share ?
Are there some things to avoid ?
Thanks !
Al

Hello Al,
you are on the right track. A typical convention I follow is:
<project>
bin - for startup scripts, etc. to run your application
build - for build scripts (not necessary if you build using your IDE. See below.)
classes - for my compiled classes
lib - for my 3rd party libraries
src - for my source code
test - for my test code (see http://junit.org/ )
That's the project hierarchy. The src (i.e. the package heirarchy) structure is another story.
As you say, you start with the reverse domain name. This is to give your packages a unique namespace. After that, your best guide is practice. Packages can be larger or smaller, depending on your coding practices. Usually you would have these (exact names may differ), plus others:
com/ppco/client
com/ppco/server
com/ppco/common
com/ppco/db
I think your break down of sun, org, etc. is a bit too much. If you would like to do so, however, I recommend you do the separation under /lib. This way, the top level project directory is not polluted by the different types of libraries in use.
Regards,
Manuel Amago.
From build above: I would suggest you always build your release distribution directly with the JDK, not using any IDE compiler. This is because Sun's JDK is the reference implementation, thus, any compatibility issues are not yours.
An easy way to achieve this is by using ANT (see http://jakarta.apache.ort/ant/ ).

Import statement and directory structure

First of all, sorry for such a long post, I believe part of it is because I am unsure of the concept of importing in Java. Secondly, Thanks to anyone who can ultimately enlighten me to the concept of import. I did ask this question before in the "erorr and error handling" forum, and the people who have helped me there did a great job. But, I believe I require a little more clarification and thus have decided to post here.
Anyhow, my question..
Could someone explain to me the concept of the import statement, or direct me to a webpage with sort of explanation for newbies? For some reason, I am having a hard time grasping the concept.
As I understand it, the import statement in Java, is very similar to the namespace keyword in C. That is to say, import doesn't actually "import" any source code, the way that the #include statement does in C.
So I suppose what my question is, say I have a java class file like below:
//filename: sentence.java
//located: c:\school\csc365
package csc365;
class sentence
//some variables here..
//some constructor here..
//some methods here..
And some sample program like the one below which implements the above..
//filename: test.java
//located: c:\school\csc365
import csc365.*;
import java.io.*;
class test.java
//creates some sentence object
//uses the object's methods
//some other things.
As I understand it, the test.java file should not compile because the csc365 package is not in the correct directory. (assuming of course, the classpath is like c:\school\csc365;c:\school )
But, ... where then should the sentence.java be located? In a subdirectory of c:\school called csc365 (i.e c:\school\csc365\) ?
And thus that would mean the test.java file could be located anywhere on the hard drive?
I suppose, I just need a little clarification on the correlation between a package's "name" (i.e package csc365; ) and its corresponding directory's name, and also how the javac compiler searches the classpath for java classes.
..So, theoretically if I were to set the classpath to look in every conceivable directory(provided the directory names were all unique) of the harddrive, then I could compile a test.java anywhere?
As a note: I have been able to get the test.java file to compile, by leaving out the import statement in the test.java file, and also leaving out the package statement for the sentence class, but I assume this is because the files are defaulted to the same package?

Hi Mary,
No, import isn't analogous to C++ namespace - Java package is closer to the namespace mark.
import is just a convenience for the programmer. You can go your whole Java career without ever writing an import statement if you wish. All that means is that you'll have to type out the fully-resolved class name every time you want to use a class that's in a package other than java.lang. Example:
// NOTE: No import statements
public class Family
   // NOTE: fully-resolved class names
   private java.util.List children = new java.util.ArrayList();
}If you use the import statement, you can save yourself from typing:
import java.util.ArrayList;
import java.util.List;
public class Family
   // NOTE: fully-resolved class names
   private List children = new ArrayList();
}import isn't the same as class loader. It does not bring in any source code at all.
import comes into play when you're compiling or running your code. Java will check to make sure that any "shorthand" class names you give it live in one of the packages you've imported. If it can't find a matching fully-resolved class name, it'll give you a message like "Symbol not found" or something like that.
I arrange Java source in a directory structure that matches the package structure in the .class files.
If I've got a Java source file like this:
package foo.bar;
public class Baz
   public static void main(String [] args)
        Baz baz = new Baz();
        System.out.println(baz);
   public String toString()
       return "I am a Baz";
}I'll store it in a directory structure like this:
root
+---classes
+---src
      +---foo
           +---bar
                +---Baz.javaWhen I compile, I go to root and compile by typing this:
javac -d classes foo/bar/*.javaI can run the code from root by typing:
java -classpath classes foo.bar.BazI hope this wasn't patronizing or beneath you. I don't mean to be insulting. - MOD

Standby Redo Log Files and Directory Structure in Standby Site

Hi Guru's
I just want to confirm, i know that if the Directory structure is different i need to mention these 2 parameter in pfile
on primary site:
DB_CONVERT_DATAFILE='standby','primary'
LOG_CONVERT_DATAFILE='standby','primary'
On secondary Site:
DB_CONVERT_DATAFILE='primary','standby'
LOG_CONVERT_DATAFILE='primary','standby'
But i want to confirm this wheather i need to issue the complete path of the directory in both the above paramtere:
like:
DB_CONVERT_DATAFILE='/u01/oracle/app/oracle/oradata/standby','/u01/oracle/app/oracle/oradata/primary'
LOG_CONVERT_DATAFILE='/u01/oracle/app/oracle/oradata/standby','/u01/oracle/app/oracle/oradata/primary'
Second Confusion:-
After transferring Redo Standby log files created on primary and taken to standby on the above mentioned directory structure and after restoring the backup of primary db alongwith the standby control file will not impact the physical standby redo log placed on the above mentioned location.
Thanks in advance for your help

Hello,
Regarding your 1st question, you need to provide the complete path and not just the directory name.
On the standby:
db_file_name_convert='<Full path of the datafiles on primary server>','<full path of the datafiles to be stored on the standby server>';
log_file_name_convert='<Full path of the redo logfiles on primary server>','<full path of the redo logfiles on the standby server>';
Second Confusion:-
After transferring Redo Standby log files created on primary and taken to standby on the above mentioned directory structure and after restoring the backup of primary db alongwith the standby control file will not impact the physical standby redo log placed on the above mentioned location.
How are you creating the standby database ? Using RMAN duplicate or through the restore/recovery options ?
You can create the standby redo logs later.

Data guard: OMF and directory structure

hi everybody,
i guess this problem is not too complicated, but maybe i´m missing something.
assumption:
- 10.2.0.4
- data guard with physical standby (primary: node_a, standby: node_b)
- primary db_unique_name=primary, standby db_unique_name=standby
- using OMF, primary db_create_file_dest=<myDir>/oradata
- standby_file_management is set to AUTO
- want to use same directory structure for data files on both nodes (<myDir>/oradata/PRIMARY/)
data guard is working as expected so far, data files on both nodes are created in <myDir>/oradata/PRIMARY/datafile/
next assumption:
- failover is initiated
- physical standby is recreated on former primary node (node_a)
from now on, data files are created in <myDir>/oradata/STANDBY/datafile/, old data files remain in <myDir>/oradata/PRIMARY/datafile/.
is there a way to avoid a second directory (and still use the benefits of OMF)? at least at the current standby node it´s possible to avoid this by setting db_file_name_convert, but what about the new primary?
thanks for your input,
peter
Edited by: priffert on Sep 14, 2009 3:07 AM

I have a similar setup with the exception that I'm using ASM for datafiles. The issue I'm having with OMF is that if I create a datafile within a disk group that is not in the location specified by db_create_file_dest then on the standby it's created in the db_create_file_dest. Apparently this will not give me the ability to maintain the exact configuration on both primary and standby without requiring modification after role changes.

Problem with package and directory structure

Please... I need help with a directory/package structure that I don't understand
why it is not working...
I want to create a custom login SWF which several other SWF movies will use in case they need some kind of login logic (in this case it is a login logic... but the problem doesn't have anything to do with that logic...)
I have created a FLA movie (LOGIN.FLA) and two helper classes (MAINLOGIN.AS and MAINLOGINEVENT.AS)... they are all under the same directory, for example:
c:\
     abc\
          def\
               ghi\
                    login
In LOGIN.FLA, I have included the source path, c:\abc (for example).
MAINLOGIN.AS and MAINLOGINEVENT.AS, have both a package like:
     package def.ghi.login
MainLogin class uses MainLoginEvent (it dispatches events of that type)... but I don't have to import anything as all 3files are in the same directory...
LOGIN.FLA has its class defined as def.ghi.login.MainLogin
And that's all... now comes the problem:
1. If I leave everything as described and try to publis LOGIN.FLA, it throws error 5001 ("The name of the package def.ghi.login.MainLoginEvent doesn't reflect....) for class MainLoginEvent... don't understand why... it is placed exactly as MainLogin and has the same package definition!
2. I have tried several other options, but when I get the SWF to get published, then, the problem comes when trying to use this SWF from another movie:
The way to publish LOGIN.FLA with no errors is: MAINLOGIN.AS and MAINLOGINEVENT.AS with empty package definition ("package" alone...) and LOGIN.FLA with class MainLogin (not def.ghi.login.MainLogin)... LOGIN.FLA doesn't have to include source path to c;\abc in this case. This way, I can publish LOGIN and get LOGIN.SWF.
The problem now is how to use this information from another Movieclip... I want to be able to use and receive events of type MainLoginEvent but can't (it gives error 5001 again, on MainLoginEvent, saying that the name of the package '' doesnt' reflect....)... If I include the path to c:\abc\def\ghi\login on the FLA, then it gives errors in MainLogin when trying to use a class of its library...
Basically, the problem here is that, the movie which wants to use the LOGIN.SWF, is in c:\abc\def, and it is including the source path c:\abc, so if I import def.ghi.login.*
it is when it throws error 5001 (I understand why, but I dont know how to fix it...), but if I dont import def.ghi.login.* then I can't use MainLogin nor MainLoginEvent...
What is the good way of doing this kind of structure... mainly it is creating a SWF, which can be used from other SWF's and which can dispatch events, which the container SWF will capture...
If anyone can please give me a hint... THANK YOU!

Hi kglad , I don't understand the first point... "don't use absolute paths"... I'm not using them (or I don't understand what you mean).
For the second one... the structure is like:
c:\
     abc\
          def\
               LOGINCONTAINER.FLA
               ghi\
                    login\
                         LOGIN.FLA
                         MAINLOGIN.AS
                         MAINLOGINEVENT.AS
In LOGIN.FLA, I include the source path c:\abc, so MAINLOGIN.AS and MAINLOGINEVENT.AS have a package of "def.ghi.login", and the class for LOGIN.FLA is "def.ghi.login.MainLogin"... when trying to publish LOGIN.FLA, Flash throws error 5001 for MAINLOGINEVENT...¿?
What I want to get is a SWF (LOGIN.SWF), which can be loaded from any other SWF (in this example, LOGINCONTAINER.SWF). LOGINCONTAINER.FLA, has a class path "c:\abc" (the same as the other LOGIN.FLA, because of the directory structure), and it has to be able to receive events of type MAINLOGINEVENT... that is why it has to do an import of "import def.ghi.login.*" (for example)
Any idea of why it is not working (or how to organize it correctly)?
Thank you

Changing file name and directory structure for use outside of iPhoto

Hi,
I was wondering if its possible to get iPhoto to name the files from my library to reflect the names that I've given the files in iPhoto. I'm thinking along the lines of iTunes, where its possible to chose in the preferences how the files are named, and there is some logical directory structure, such as "Artist/Album/01 - Track 1.mp3". These file names are updated to reflect any changes made in iTunes.
I've heard the argument that I shouldn't ever want to do anything with the files themselves because iPhoto can do everything I would ever want to do, but I want to organize the files so that not all of my organizational work is lost if I decide to stop using iPhoto and transition to a different system. Any suggestions would be appreciated.
Thanks,
Adrian

Adrian
No it's not possible.
You can rename the files before bringing them into iPhoto, you can rename them with the titles on Export (Use the File -> Export command, it gives you the option to use the title and filename) but when it's inside iPhoto you cannot rename the files.
However, all is not entirely lost. Using Film Rolls (View -> Film Rolls) you can move pics between rolls, name rolls, create rolls and so on, as long as you do this in the iPhoto Window, and these changes will be reflected in the iPhoto Library Folder.
If at some point you decide to chuck iPhoto then (if the new app won't read iPhoto database files) you can simply export each album you've created to a Folder (using the File -> Export command as I suggest above), this, along with exporting slideshows will preserve your organisational efforts.
The iTunes database has a rather simple job to do: track a file and it's assorted metadata. iPhoto, on the other hand, tracks a file and it's assorted metadata, plus a Modified version, plus a thumbnail. If you consider what happens when you edit a pic, for instance - Copy Original, perform edit, save modified version, remove Original Thumbnail and then create new one - you can see it's a rather more complex job.
Finally, the standard warning: It is strongly advised that you do not move, change or in anyway alter things in the iPhoto Library Folder as this can cause the application to fail and even lead to data loss. Any changes you make must be made in the iPhoto Window.
Need more info? by all means post again.

PC - Moving catalog and directory structure to a new HD

Having filled my internal HD with images, I went out and purchased a new and bigger external hard drive. I want to move my images to the new drive while preserving both my directory structure and catalog information. From what I can see of the "move" command in PS Elements, it moves selected images to a new directory, but that's not what I want to do. I probably have a hundred named folders and I would like to keep the images in folders of the same name on the new drive. I don't want to have to move one directory at a time. Copying through the file manager can obviously do this, but I don't know if it will preserve my tags, etc.
Is there a straightforward way to move files from one drive to another that preserves both directory structure and catalog information?
Thanks in advance.
Artie

Humm, this is strange-Version 4 is supposed to move entire folders; Version 3 did not do this.
Okay, Plan B.
Open Elements and do a Full Backup and point to your external hard drive.
When this has finished running, do a Restore. You should get a pop up asking if you want to use the existing folder structure. Answer Yes and point to your External HardDrive (EHD). This should copy your photos and the Organizer file over to your (EHD).
Now look in Preferences under Files (I think, don't have program open) and you will see one value for where to store photos and one for Organizer location. Change these to your EHD so future photos and tags/collections are written to the EHD.
Verify all your tags and collections came over correctly.
If you are satisfied the transfer went correctly, you can erase your photos from your hard drive to free up space. You can also delete the Organizer file if you want.
Option 2-Use Windows Explorer and move all the files from your hard drive to your EHD. This will keep your folder structure, but will cause havoc with Organizer.
Open Organizer and do File>Reconnect All Missing. It will be all of them. You should have an option to change the drive to your EHD. It may take quite a while to reconnect all of them, but since all the folders/files are the same name it should find them all.
If you wish, you can change the drive location manually. However, I've found many users 1) do not have MS Access on their machine and 2) are not experienced in using the program. If you are comfortable with the program, let me know and we'll get some directions.
Finally, I see a copy of the post in the Technical side. Since most forum users read both sides of this forum, I'm going to reference this thread in that post so anyone can see what we have tried so far.

Some questions about Unity 4.0 and IPC

I have a couple of questions and I was looking for "real world" answers, not specific answers from the design guide.
1.What is this bandwidth requirement between Exchange and Unity and what is it used for?
2. What sort of issues would we experience if we placed the Unity UM Server at the Colo and placed the Exchange server at the customer premise; with a single T1 between the sites?
3.What else is involved with a Unity UM install vs. a Unity VM install?
4.Does the Unity UM and Exchange servers have to be running AD?
5. Can Unity or the Exchange box be the Domain Controller? Or does it need to be a separate server?
6. Where does a vm message get streamed from? The Unity server or the Exchange server?

No you do not pay for FaceTime. It uses your WiFi network, so if you have access to WiFi it is free.
There is no server required for FaceTime, it will use a direct device to device protocol.
I can't answer the question about using phones in different countries as that will depend on if you buy a phone that is locked to a carrier.
If you buy a phone in Germany and it is locked to a German phone network then it will most likely not work with a SIM from Turkey. You would need to buy an unlocked phone which are very expensive as they do not have any carrier subsidy applied to the price.

Question about using 10g/11g and APEX ...

Hi,
I just recently learned of Oracle's APEX and have a few questions about using it.
Can I use APEX with express, standard, and enterprise editions of 10g and 11g?
Are all of these free to use?

You might want to read about APEX rather than jumping into questions that are reasonably well documented. Info at http://www.oracle.com/technology/products/database/application_express/index.html
Your specific questions:
1) Apex is a package that can be installed into any properly licensed database.
2) The price for the production license of the database varies by edition.
The price for Express Edition is $0 for use in production. Part of the cost for that edition is 'no Oracle Support based support, no patches, data volume limitation, etc.'

Questions about JVC GZ HD7 and Final Cut

i'm planning to buy a JVC GZ HD7, but i have some questions about it...
My imac configuration is
Imac 20" late 2006
1 Gb Ram
Leopard 10.5.2
Final Cut Studio 2
Ok
So my questions are:
1- When shooting the best setting for me is the 1440cbr, or 1920x1080
is better? i would like to have progressive instead of interlaced
moviefiles, but for what i have read the JVC HD7 only shoots interlaced...is possible to turn them into progressive after working in final cut?
2- In Final Cut Pro what are the sequence settings and the video
settings for a video shoot from this camera?
I would like to know the best settings possible for me,
regarding that i would like to edit in real time, no rendering needed,
and to have the best image quality that this camera can offer...

FCE is designed to work with DV/HDV files. It cannot work natively with MPEG2 files. You will need something like MPEG Streamclip to convert your files to a format that FCE understands
Streamclip is free but you need to buy Apple's MPEG Playback Component to make it work

Techie Question about iWeb, outbound links, and Google Analytics

Hi,
I have a kind of pretty technical question about using Google Analytics (GA) with iWeb sites to measure clicks on outbound links. Here's the setup:
1) My website's online, and GA is working properly.
2) I don't sell stuff directly, but I do have a "Purchase" page which contains a link to a specific Amazon page.
3) I'm pretty sure I can measure how many people go to the Purchase page using GA, but how do I measure whether visitors click on the Amazon link? It would be interesting to me to be able to gauge what the conversion rate is; that is, how many people actually proceed to purchase the product at Amazon.
I've checked the GA instructions and there's a page about manually tracking clicks on outbound links but it requires some code inputting. I know zero about coding, but I'm pretty sure that in iWeb you can't get access to the source code to input the required code.
Am I wrong about this? And if I am, then does anyone here know how to measure the clickthrough rate?
Anyway, hope you can help. Thanks in advance.

I don't know about the link tracking but you could have the link take you to a redirect page which automatically sends them to Amazon.com after a preset time, 0 seconds to whatever you'd like. You can put a counter on that redirect page, like StatCounter. StatCounter can tell you how many, from where they came, i.e country and area, repeat visits, etc.
Tutorials #12 & #13 describe how to put a visible counter on a page but with a redirect page you wouldn't have to bother since it wouldn't be seen. You can get all of your information from your account on the StatCounter site.
The redirect page would be a simple plain text page titled redirect.html and would look like this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="refresh"
content="0; Destination URL">
<title>Redirecting or whatever you'd like to appear at the top of the browser</title>
</head>
<body>
</body>
</html>
0 Is the number of seconds to wait before redirecting the visitor. If set to zero the visitor would not know they were being redirected. Replace Destination URL with the Amazon URL you want them to go to.
