HDD Error -36 question: Am I on the right track here?

Hey folks,
HDD question here.
I have a 13” early ’11 MBP, 320 GB HDD, came with Lion, now running ML, anticipating a soon upgrade to Mavs. 16 GB of RAM. All updates current.
Started running out of HDD space with all my photo and video work and about a year and a half ago I bought a 1 TB WD portable, used it lots, no problems.
Last night, I bought a 2 TB WD portable. Started copying my Photo folder over, and I got lots of the dreaded Error 36, “The Finder can’t complete the operation because some data in “IMG_0596.CR2” can’t be read or written. (Error code -36)”
This is the first time I have seen this error with either/any drive.
So I have these two external WD drives with two cables, so I tried copying one of the offending folders to both drives
(both the 1 TB and the 2 TB, one at a time) using both/either cables. Both drives and cables give me the same error.
In short, either drive, in either USB slot, with either cable gets the same error.
In shorter, I think I have eliminated the external drives as the source of the problem.
Thoughts?
FYI, the 1 TB is Mac OS Extended (Journaled)
The 2 TB is MS-DOS (FAT32), though I am 99% sure I will be converting it to Extended/Journaled ASAP. (thoughts?)
In the last 6 months I’ve noticed things running slower…a LOT slower, at least it seems like.
Granted, my HDD has been a bit packed, but I’ve offloaded a lot too.
More beach ball action than seems to be normal, etc etc, even with all this RAM.
My total boot time (cold) is:
1:30 to login screen
1:57 to loaded desktop.
By way of comparison, this same MBP will boot to Snow Leopard off an external drive in 1:13 to a loaded desktop.
My question:
I’ve HEARD that the Error -36 can be a likely precursor to drive failure.
[U]Given what I’ve mentioned here, is the most likely candidate for a failed drive my main HDD?
Are there other things I should check first?[/U]
I have a chance to buy a Seagate Momentus XT 750 GB hybrid SSD drive out of a Mac, and it has very little use on it.
(I'd be buying from a family member I trust).
Thoughts on that?

I might not explain my question well in my previous post -- there is no business logic involved in what I am doing to go from the first entity bean to the second entity bean and to go from the second entity bean to the third entity bean.
Based on the login information, I have to go through those entity beans to find the very specific row in the third table in order to get the data field I need. That is to say, only thing involved is searching for rows.
In my view, session bean -- > 1st entity bean -- > 2nd entity bean -- > 3rd entity bean
1. session bean -- > 1st entity bean: remote call and returns the key to the 1st entity bean for locating the 2nd entity bean
2. 1st entity bean -- > 2nd entity bean: local call and returns the key to the 2nd entity bean for locating the 3rd entity bean
3. 2nd entity bean -- > 3rd entity bean: local call and then returns the value of the specific field to the session bean
The alternative approach is:

J2EE Design Question -- Am I On The Right Track?

There are multiple tables in my database. Each table has a primary key, and the table that relates to other tables has foreign keys. I have to match the primary key and foreign key to go from one table to another. The specifics are spelled out below:
The first table has login, pwd, and a primary key as fields, the second table contains completely different fields plus a primary key and foreign keys. The fields in the third table are different from those in the first and second tables plus its primary key. Queries to the third table can be made only if the user login and pwd are found in the first table, and through the second table's relation to the first table and the third table�s relation to the second table.
The fields of all those tables may be accessed concurrently, but the fields are read-only (for the time being).
I have a servlet to handle browser interactions. And I have a session bean to handle the workflow and business logic. However, I am confused with the choices between VO and entity beans.
I first thought that I should use value objects to represent the data fields of the specific rows I looked for in those tables. Here is what I read about Value Object:
"If a business object merely represents a structure to hold data fields, and the only behavior it provides are get and set method for the fields, then it would be wasteful of system resources to implement it as an enterprise bean. To avoid expensive remote methods calls (system resources and network bandwidth) to get the value of entity object fields, a value object is used to represent the details of the entity object. Only one remote call is required to retrieve the value object and then a client�s request to query the state of the object can then be met via local get methods on this details object."
On my second thought, I think I should use entity beans to represent the specific rows I am looking for in those tables because I must use primary key and foreign key relations to go from one table to another.
I do not use DAO because I am using CMP. The first call is within the session bean. It is a remote call to look for a specific row in the first table in my database. Subsequently, the mapping of the row in the first table to the second table, and the mapping of the row in the second table to the third table are all invoked on the �local" interfaces of those entity beans.

Please advise if this is the right design. Am I on the right track? Is there improvement to be made?

1. tags around your raw output!1. [ code ] tags around your raw output! 1.
Looks pretty now. Always wondered how that was done
2. Did you deplete the usefulness of https://wiki.archlinux.org/index.php/KVM to its entirety?
that is what I am trying to follow.
Is there more modules needed?
Did it work correctly?
It lacks information on how to add modules.
I got it working the first time by following multiple how tos and in the end I do not know which bits I done was needed and which bits was not and they did.
By the way. You did not answer the question.
Am I on the right track?
After all I am in the newbie corner

Calling a local Webservice from ECC ABAP - Am I on the right track?

Hi all
In my NW2004s landscape I have an ECC system (ABAP 6.40, Java not configured/linked) and an XI system (6.40). My requirement is to call a Webservice (WS) from the ECC system.
I've converted an existing Java class (that contains 3 methods) to a webservice (WS) using NWDS. This WS has then been deployed to the XI system as it is the only one with a JAVA system. I'm able to view and test the WS methods using the Web Service Navigator on the XI system. The wsdl for the WS that was generated has the following format "http://<server>:<port>/<webservice name>/<configuration name>?wsdl (No .asmx extension as per most of the examples on SDN...not sure if this matters).
My understanding is that I should be able to create a client proxy in my ECC system (via Enterprise Services in SE80) using this wsdl and I can also configure a logical port throught txn LPCONFIG. I should then be able to utilise ABAP to call this webservice?
I've found the blog "/people/thomas.jung3/blog/2004/11/17/bsp-a-developers-journal-part-xiv--consuming-webservices-with-abap detailing this (for a 6.40 system)... but when I attempt the program I get a soap 111 error code Unallowed RFC-XML Tag(SOAP_EINVALDOC).
Am I on the right track? Is it possible to call the Webservice from ECC ABAP?
There are no dumps for me to analyse and I've also tried putting on RFC trace with no success.
Could it be that the WS is not correctly formed even though it works fine when tested from the WS Navigator on the XI system?
Thanking you in advance.

The planning which you have mentioned in your reply is of imense value I will start to do that immidiately, also the constant testing through Digital editions.

Strategy Pattern, Am i on the right Track?

The question:
Design a small, prototype, application, which creates, stores and amends warehouse records. This may have little more than a StockItem class.
Using each of the patterns Strategy, Decorator, Adaptor and in turn provide three different adaptations to your prototype application which will enable a user to view the warehouse records in at least three different ways, e.g. by location, alphabetically, by value, by quantity in stock, as continuous plain text, as formatted text, in a list pane, as a printout etc
My Code
package warehouse;
public class StockItem
    private int id;
    private String describtion;
    private double price;
    private int quantity;
    private String location;
    ViewByLocationBehavior locationVar;
    public StockItem()
    public void setId(int id)
        this.id=id;
    public int getId()
        return id;
    public void setDescribtion(String describtion)
        this.describtion=describtion;
    public String getDescribtion()
        return describtion;
     public void setPrice(double price)
        this.price=price;
    public double getPrice()
        return price;
    public void setQuantity(int quantity)
        this.quantity=quantity;
    public int getQuantity()
        return quantity;
    public void setLocation(String location)
        this.location=location;
    public String getLocation()
        return location;
    public void setViewByLocationBehavior(ViewByLocationBehavior locationVar )
        this.locationVar=locationVar;
   public void displayByLocation()
    locationVar.displayByLocation();
    public String toString()
        return String.format("%d %S %f %d %S",id ,describtion,price,quantity,location);
}The interface
package warehouse;
public interface ViewByLocationBehavior
    void displayByLocation();
}Concrete classes arepackage warehouse;
public class PlainText extends StockItem implements ViewByLocationBehavior
    public void displayByLocation()
        System.out.println("Display PlainText");
package warehouse;
public class FormattedText extends StockItem implements ViewByLocationBehavior
    public void displayByLocation()
        System.out.println("Display Formatted Text ");
package warehouse;
public class ListPane extends StockItem implements ViewByLocationBehavior
    public void displayByLocation()
        System.out.println("Display ListPane");
package warehouse;
public class PrintOut extends StockItem implements ViewByLocationBehavior
    public void displayByLocation()
        System.out.println("Display PrintOut ");
package warehouse;
public class StockTest
    public static void main(String args[])
        StockItem obj = new StockItem();
        obj.setViewByLocationBehavior(new PlainText());
        obj.displayByLocation();
        System.out.println(obj.toString());
}But my questions is Am i on the right track applying the Strategy pattern?
Because next i will make the other Interfaces: View by alphabetically, by value, by quantity, and their Concrete Classes are
Display as continuous plain text, formatted text, in a list pane, and printout.
Each interface have four concrete classes
Need your comments Please?

But my questions is Am i on the right track applying
the Strategy pattern?Your assignment explicitly calls for the strategy pattern:
"> Using each of the patterns Strategy, Decorator,
Adaptor and in turn provide three different
adaptations to your prototype application which will
enable a user to view the warehouse records in at
least three different ways, e.g. by location,
alphabetically, by value, by quantity in stock, as
continuous plain text, as formatted text, in a list
pane, as a printout etc"I'm not sure I care for that interface much. I would have expected something more like this (I'm not 100% sure about the parameter that I'd pass, if any):
public interface StockItemFilter
    List<StockItem> filter(List<StockItem> unfilteredStockItems);
}Now you'll pass in an unfiltered List of StockItems and return the List of appropriate StockItems filtered alphabetically, by location, etc. If you want to combine the fetching of StockItems with filtering, replace the unfiltered List with some Criterion.
Your ViewByLocationBehavior doesn't seem to accept any input or return anything. What good is it?

Need to reinstall HTML DB - Am I on the right track????

I have a problem with my admin password not working. This is on a single user computer with htmldb installed in a local personal Oracle 9 database that I use specifically for development and testing. I don't know why the HTML DB admin password stopped working as it is just a lower case version of the ADMIN name. I can still access the user I created and have been working with that. No one else has access to this computer - so somehow I managed to screw something up.
My question is - if I drop / wipe out the FLOWS_020000 and FLOWS_FILES users and then reinstall HTML DB, and then recreate my admin and user(s), will this solve my problem??
Is there anything else I need to do to restore HTML DB?? I assume the HTTP SERVER should still be ok?
I guess what I really need is confirmation that I am on the right track and not about to totally screw up a partially functional HTML DB install.
Thanks for your help

Please ignore the above thread - problem solved. My brainfart. Did 2 installs - kept the handwritten docs for the wrong one. Tracing my way through the install program jarred the memory.

I would like to convert a continuous waveform (created in Labview with the waveform generator vi) into digital form...am I on the right track (see below)

I would like to simulate a sample and hold circuit. I was thinking of using the zero order hold vi (for continuous to discrete conversion) in combination with the AC to DC vi? Am I on the right track, or could anyone suggest a better way to do this? Many thanks in advance!

Hi,

Am I on the right track with the 'secret' OPTION key?

Everyone has questions about 'sharing' itune libraries. I just wanted to know how to keep them separate!
After reading I got this far:
Hold down the option key to view a different library, internal or external as long as it is plugged in and on the desktop.
How to open alternate iTune library
What happens, it a dialog comes up saying that the other users folder is locked or I don't have permission to access.
Troubleshooting permissions on locked folders
then I found a lot of great key cuts (for iPod) too~but using the option key in various configurations;
Keyboard shortcuts
itunes is on an external drive which complicates things, i think. Am I on the right track if
* have to partition the external HD, one for each user.
* drag the actual user folder to the external drive
* change itune music folder for each user to selected partition
* select "copy files to itunes music folder..." (which I still don't really understand)
* make sure sharing is on all the way around
And another discussion of "add to library" and more info on how to use play lists would be helpful.
Is there a less cumbersome way to
Load itunes, load a particular library
then add to it via a playlist?
First Gen iMac G5 17" Mac OS X (10.4.8) iMac G3 350/6GB/1GB/OSX Panther

See, on the external, I can't have three folders that all say iTunes music folder, each one belonging to a different user.
Sure you can. Put them in separate folders (John's music, Mary's music and Sam's music).
But you should be creating new iTunes folders, not simply iTunes music folders. The iTunes music folder is in the iTunes folders but so it the iTunes library file.
Any reason you want the music separated? You can put it all in one library. Everyone uses the same and simply create a playlist of the music they want. This way, if you have any of the same music, you won't have it on the computer more than once.

I want to know if i am on the right track

'm still working on my DNA sequencing project (i am further along thank goodness) but now, i want to check my thought process.
Okay, i have to write a new method public void addEdge(int i, int k)
that creates an edge sequence between vertex j and k.
What these need to do is take the watson-crick compliment of the last half of j concatenated with the watson-crick of the first half of k. So it looks kind of like this:
sequence
ATTATAAACCA
watson-crick edge compliment
TGGTTTATAAT
here is my thought process
1. take the initial sequence array and divide it by 2
2. then go through the first half and change the compliments
3. then do the same with the second half and concantenate them together
so it would look like
for(int i = 0; i < seqArray.length/2; i++){
base = rand.nextInt(4);
if(base==0)
tube+="T";
else if(base==1)
tube+="A";
else if(base==2)
tube+="C";
else if(base==3)
tube+="G";
for(int j = seqArray.length/2; j < seqArray.length; j++){
base = rand.nextInt(4);
if(base==0)
tube+="T";
else if(base==1)
tube+="A";
else if(base==2)
tube+="C";
else if(base==3)
tube+="G";
new Sequence(tube)= seqArray[i] + seqArray[j];What do you think? am i on the right track?
}

Something like the following?
public class WC {
    private static char complement(char base) {
        switch (base) {
            case 'A': return 'T';
            case 'T': return 'A';
            case 'G': return 'C';
            case 'C': return 'G';
            default:
                throw new IllegalArgumentException("unrecognised base "+base);
    private static char[] complement(char[] bases) {
        int size = bases.length;
        char[] complement = new char[size];
        for (int i = 0; i < size; i++) {
            complement[i] = complement(bases);
return complement;
public static void main(String[] args) {
String s = args[0];
String s1 = s.substring(0, s.length()/2);
String s2 = s.substring(s.length()/2);
char[] c1 = s1.toCharArray();
char[] c2 = s2.toCharArray();
s1 = new String(complement(c1));
s2 = new String(complement(c2));
System.out.println(s);
System.out.println(s2+s1);

Selling Macbook and erasing and restoring to Lion. Am I on the right track?

Hi All,
I'm planning to sell a Macbook from 2008 that originally came with Snow Leopard. I have since upgraded it to Lion.
I've read the discussions and I think I'm on the right track. So far, I restarted and held the command and R keys. That brought me to Disk Utility. I chose "Macintosh HD" from the left hand bar and the format of "Mac OS Extended (Journaled)", selected to erase it, and chose the 7 pass security option.
In addition to being able to choose "Macintosh HD" there was "Mac OS X Base System". However, I don't think I was able to perform an erase function on that. Perhaps I can just leave that alone.
Anyway, I successfully erased Macintosh HD with 7 pass. I assume my next step would be to reinstall Lion. When I try to I'm told to connect to my wi fi network and re-install Lion from the Apple site. I had previously upgraded to Lion using a thumb drive which I no longer have. I guess I have no choice but to reinstall from the Apple site. That's fine for me as long as I get it to work.
Before doing so though I'd like to know whether I missed any steps. Was there anything else I should have done before I go ahead and reinstall Lion?
Also, will the person buying the Macbook be able to operate it since the Lion OS would be tied to my Apple ID?
Thank you.

Follow these instructions step by step to prepare a Mac for sale:
Step One - Back up your data:
       A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
       B. Clone to an external drive using using Carbon Copy Cloner.
          1. Open Carbon Copy Cloner.
          2. Select the Source volume from the Select a source drop down menu on the left side.
          3. Select the Destination volume from the Select a destination drop down menu on the right
              side.
          4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
              sure to opt for that.
               Destination means a freshly erased external backup drive. Source means the internal
               startup drive.
Step Two - Prepare the machine for the new buyer:
          1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
          2, Remove any Open Firmware passwords or Firmware passwords.
          3. Turn the brightness full up and volume nearly so.
          4. Turn off File Vault, if enabled.
          5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
Step Three - Install a fresh OS:
     A. Snow Leopard and earlier versions of OS X
          1. Insert the original OS X install CD/DVD that came with your computer.
          2. Restart the computer while holding down the C key to boot from the CD/DVD.
          3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
              Optionally, click on the Security button and set the Zero Data option to one-pass.
          4. Install OS X.
          5. Upon completion DO NOT restart the computer.
          6. Shutdown the computer.
     B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
         Note: You will need an active Internet connection. I suggest using Ethernet if possible because
                   it is three times faster than wireless.
          1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
              Utilities window appears.
          2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.
          3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
              on the Erase tab in the DU main window.
          4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
              and set the Zero Data option to one-pass.
          5. Click on the Erase button and wait until the process has completed.
          6. Quit DU and return to the Mac OS X Utilities window.
          7. Select Reinstall Lion/Mountain Lion and click on the Install button.
          8. Upon completion shutdown the computer.
*If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

Could you please tell me if I am in the right track?

I am required to develop a online shopping web application which uses JSP and EJB. The first page I need to create is the login page. I would like to know if I am in the right track to implement this system in EJB design pattern.
I got the following classes:

Any advice would be very much appreciated.
Many thanks to you all.

EJB stuff looks ok.
The only comment I could make is that the UserBean should probably implement the User interface
Mixing JSP and scriptlet code is bad.
If you need to do java code most of the time that should be in a Servlet, which then uses the request dispatcher to forward to a jsp to display the result.
The entire java code for retrieving the EJB and testing for login could be in a servlet. It is completely unrelated to displaying a login page.

Error "need to place tarball in the right location" jre & jdk upgrade

Using pacaur to upgrade seom AUR packages - namely jre and jdk Iget this set of errors, ad infinitum:
Due to a change in how Oracle handles the Java SE License Agreement
you are required to:
1) accept the license and download the tarball (jre-7u4-linux-x64.tar.gz) yourself:
http://www.oracle.com/technetwork/java/javase/downloads/jre-7u4-download-1591157.html
2) move it to $startdir (/tmp/pacaurtmp-larry/jre/)
-> If saved in ~/Desktop/, ~/Downloads/ or /tmp/, it will be auto-moved for you
-> Press any key to continue..
==> ERROR: You need to place the tarball in the right location
-> Press any key to retry (or Ctrl-C to cancel)..
==> ERROR: You need to place the tarball in the right location
I have downloaded the java tarball and placed it in the correct directory. Still get same errors as above,
any ideas why?

Thanks for your offering. I have a bit of house cleaning and rearranging due
to my knowing I bought the CS4 software and had installed it and thinking
things would work as before I did not realize that by buying and installing
another software program Proshow Producer on an external HD and then
learning from the company that it had to be on C:/ to work properly. That
forced moving other things around, like CS2, CS3 and CS4 and leaving CS on
C:/ then reinstalling Producer as CS works fine for the pictures used in
Producer and all related files on C: as all my other working photos had to
move with the software!! With 5 and a half terabits on 6 external HD's I got
careless and did not properly set things set up as I should have in
anticipation of my current problem and Adobe's programers, not being mind
readers programmed things to look on C: when CS2,3, and 4 lived elsewhere.
It's all a mess but I do have my serial numbers and did discover, thanks to
your Creative Suite Cleaner Tool offering I found a link to Adobe's original
CS4 trial files that I was told by Adobe were no longer available due to CS6
and I can re-download CS4 there and use it since at the moment my CS4 is
hiding from me. I think a clean re-installation should work before running
the 'cleaner' with its' gottchas. I shall send a later follw up when things
are successfully reloaded. If you think of anything else of value, I would
certainly appreciate your knowledge!

Can this be done and am I on the right track?

I guess I just need some advice on how to accomplish this - below is what I am trying to work with right now. I am new and trying - so dont laugh if its stupid.
I need to get information out of the table web groups to build the query for the second database call. I was hoping that I would be able to dynamically name the result set as it iterates through. I am having no luck with that . Is that even possible?
Let me know if you need more information.
Statement contentStmt = Conn.createStatement();
     String group = "SELECT * FROM MT."+ newID +"_Web_Groups ORDER BY orderID";
     ResultSet rsGroup = contentStmt.executeQuery(group);
               while(rsGroup.next()) {
               String buildGroupTable = rsGroup.getString(2); // Stored procedure name
               String buildGroup = rsGroup.getString(3); // Heading for section
          CallableStatement cs+"'buildGroup'" = Conn.prepareCall("{call mt." + buildGroupTable + "('"+ areaID[i] + "')}"); // make stored procedure call
          ResultSet rs+"'buildGroup'" = cs+"'buildGroup'".executeQuery();
          out.println("<tr><td class='reportHeader' colspan=" + colCOUNT + " align='center'>" + buildGroup + "</td></tr><tr>");
               if(rs+"'buildGroup'".next()) {
                    while(rs+"'buildGroup'".next()) {
                         displayContent = "<tr>";
                         for ( int x = 0; x < colCOUNT; x++ ) {
                              displayContent = displayContent +" <td class='reportTxt'> "+ rs" + buildGroup + ".getString(x+1)+"</td>";
               } else {
               out.println("<tr><td class='reportNone' colspan=" + colCOUNT + " align='center'> No Tooling to report. </td></tr><tr>");
               out.println(nextWK + "</tr>");

Am i on the right track for establishing my client connection with BC4J?

I am developing web-application with BC4J JSP project now. However, I find the auto-generated page not that useful as they are not flexible enough. Then, I decided to write coding by myself. But the first problem is - how to write the coding for client connection? To make maintenance easy, I would like to place those connection code in a class file instead of hard-coding each connection details in my JSP or Servlet page.
Question 1: Through the examples I search in my JDeveloper (Candidate 2) directory, found a file TestClient.java in the \BC4J\samples\Caching\src\demo directory with the following codes:
// Create an instance of the application module by name, using local mode
String _am = "demo.DemoModule"; // Fully-qualified application module name
String _cf = "DemoModuleLocal"; // Configuration name for connection info
ApplicationModule am = Configuration.createRootApplicationModule(_am,_cf);
// Find the Managers view object by name in the application module
ViewObject mgrVO = am.findViewObject("Managers");
// We're done with the AM instance, so release it
Configuration.releaseRootApplicationModule(am,true);
Is it for testing only or really useful for the production environment? Am I doing the right thing if i use such method to establish my web client connection? What's the pros and cons for using this method? Any other better alternatives?
Question 2: As I know BC4J automatically takes care of connection pooling as a default manner since version 3.2. Can I still use the following statement
session.setAttribute("user_name", user_name); //Set session attribute
String user_name = (String) session.getAttribute(user_name); // Get session attribute
to capture and assign client session correctly for individual clients?
Question 3: What codes should I use to achieve 'Transaction' update, which assembles the coding as follows:
Connection.setAutoCommit(false); //disable auto commit
connection.commit();
connection.rollback();
connection.close();
Thanks for answering!!!

What's the pros and cons for using this method? Any other better alternatives?The Configuration API (createRootApplicationModule, releaseRootApplicationModule) will work. However, please note
that it is intended for java clients that will hold an ApplicationModule reference for a long duration. The BC4J web
frameworks (represented, for example, by the ApplicationModule and ReleasePageResources tags) all use the
SessionCookie interface to acquire/release ApplicationModule instances on a per request basis. This will allow
better scalability. Please see the pooling sample / documentation / javadoc for more information about using these
APIs. The pooling sample servlet is located in \BC4J\samples\Pooling\src\demo\TestPoolServlet.
Question 2: As I know BC4J automatically takes care of connection pooling as a default manner since version 3.2. Can I still use the following statement
session.setAttribute("user_name", user_name); //Set session attribute
String user_name = (String) session.getAttribute(user_name); // Get session attribute
to capture and assign client session correctly for individual clients?BC4J will not interfere with your use of the HttpSession context. How do you intend the "user_name" to be used? Do
you intend it to represent the DB user, JAAS user, etc. If you intend it to be used as the DB user you will need to declare
the "user_name" to BC4J. Please see:
http://technet.oracle.com/products/jdev/howtos/bc4j/howto_dynamic_jdbc.html
Question 3: What codes should I use to achieve 'Transaction' update, which assembles the coding as follows:
Connection.setAutoCommit(false); //disable auto commit
connection.commit();
connection.rollback();
connection.close();ApplicationModule.getTransaction().commit();
ApplicationModule.getTransaction().rollback();
If you are using the Configuration or SessionCookie APIs, as mentioned above, then the connection lifecycle will be
managed for you. So, you should not need to invoke connection.close().
Thanks for answering!!!
Hope this helps.
