HowTo: Use Thunar's Bulk Rename with Dolphin
I thought I would post a quick note here on how to use Thunar's Bulk Rename tool with KDE's Dolphin file browser.
Background
I am aware of KRename, but frankly, I find it a bit too complex. I prefer Bulk Rename because it is simpler, and because I often use regular expressions to rename files, which I find a bit quicker to accomplish with Bulk Rename than with KRename.
Prerequisites
Before getting started, one should make sure that dolphin and thunar are installed. This can simply be checked with the following pacman command:
pacman -Qs 'thunar|dolphin'
The output on should be similar to this:
local/kdebase-dolphin 4.14.3-1 (kde kdebase)
File Manager
local/kdesdk-dolphin-plugins 4.14.3-1 (kde kdesdk)
Extra Dolphin plugins
local/thunar 1.6.3-2 (xfce4)
Modern file manager for Xfce
local/thunar-volman 0.8.0-2 (xfce4)
Automatic management of removeable devices in Thunar
KDE Service Menu Entries
A kde service menu entry is, in most simple terms and for the purpose of this 'HowTo', a file that defines an option that can be added to e.g. dolphin's right-click menu. These services are by default in:
/usr/share/kde4/services/ServiceMenus/
... but one can also add a service to the local configuration, which I recommend, unless you want the Bulk Rename feature to appear system wide.
To add a service entry locally, open a Terminal and create the 'ServiceMenus' directory if it doesn't exist yet:
cd ~/.kde4/share/kde4/services/
mkdir ServiceMenus
cd ServiceMenus
Finally create the service entry that will make 'Bulk Rename' appear as a right-click option in dolphin. To do so, use your favorite text editor and create a file called 'bulk-rename.desktop' with the following content:
[Desktop Entry]
Type=Service
ServiceTypes=KonqPopupMenu/Plugin
MimeType=all/all;
Actions=BulkRename;
X-KDE-StartupNotify=false
X-KDE-Priority=TopLevel
[Desktop Action BulkRename]
Name=Bulk Rename
Exec=thunar -B %U
Save this file as 'bulk-rename.desktop' in the previously created service menus directory (~/.kde4/share/kde4/services/ServiceMenus), and you're done!
Be sure to restart dolphin if it was already running. Select a couple of files (it works with folders, too), right-click, and select 'Bulk Rename'. Thunar's Bulk Rename will pop up with the selected files, ready for your renaming actions.
Cheers,
DrTebi
Thanks for wriitng that. I suggest adding it to the wiki. That way the community can help maintain it.

HOWTO: Use BC4J With or Without DB Triggers
This HowTo describes how to use BC4J, database sequences and triggers
and what are the ramifications.
INTRODUCTION
BC4J has the ability to work with database sequences in order to obtain a
unique value when inserting records. BC4J also has the ability to
work either with a 'before insert' trigger which automatically creates
a new unique value for the primary key or without a trigger. When not using
a database trigger, BC4J also has the ability to obtain the sequence value
and set the primary key value.
Before discussing the ramifications of using one approach or the other, let's
show examples of how to use both approaches:
BC4J & sequences WITH a database trigger
and
BC4J & sequences WITHOUT a database trigger
HOWTO DEMONSTRATION STEPS
To illustrate both scenarios a simple database setup script is provided which
creates two tables:
CUSTOMER_NT which DOES NOT have a before insert trigger and
CUSTOMER_WT which DOES have a trigger.
Database Install Script:
<code>
drop trigger customer_insert_trigger;
drop table customer_wt;
drop table customer_nt;
drop sequence customer_wt_seq;
drop sequence customer_nt_seq;
create sequence customer_wt_seq start with 1;
create sequence customer_nt_seq start with 101;
create table customer_wt(
id number,
name varchar2(30),
constraint
customer_wt_pk
primary key (id)
create table customer_nt(
id number,
name varchar2(30),
constraint
customer_nt_pk
primary key (id)
prompt Inserting data...
insert into customer_wt (id, name)
values (customer_wt_seq.nextval, 'Mickey');
insert into customer_wt (id, name)
values (customer_wt_seq.nextval, 'Goofy');
insert into customer_nt (id, name)
values (customer_nt_seq.nextval, 'Daffy');
insert into customer_nt (id, name)
values (customer_nt_seq.nextval, 'Porky');
commit
prompt Creating trigger
create trigger customer_insert_trigger
before insert on customer_wt for each row
begin
select customer_wt_seq.nextval into :new.id from dual ;
end;
</code>
The next step is to create the DEFAULT Entity Objects and View Objects using
the Business Components Wizard.
USING BC4J WITH A DATABASE TRIGGER
Let's modify the entity object CustomerWt so it can use the database trigger.
Edit the entity object CustomerWt by right-clicking in the navigator.
Click on the 'Attribute Settings' tab and edit the ID attribute.
- Uncheck 'Mandatory'checkbox. This allows you to insert without a value for the primary key
- Check 'Refresh after Insert'. This obtains the value from the database generated by the trigger.
- Check 'Updateable While New'. Id is only updateable when inserting.
Click finish to complete the wizard. Save all and recompile the project.
Now let's test our work.
In the navigator right-click the application module and select 'Test..'. This will launch
BC4J's built in tester. Connect to the application.
In the tester double-click the CustomerWtView view object to run a test edit form.
After the edit form renders, navigate through the existing records using the navigate
buttons on the edit form. Now let's insert a record to execute the trigger.
click on the '+' button to insert a record. Enter a value in the 'Name' field and commit the change.
Observe that a new value has automatically been inserted into the Id field.
That's it! You have successfully used BC4J and a database trigger.
Now let's try it without a trigger..
USING BC4J WITHOUT A DATABASE TRIGGER
Now edit the entity object CustomerNT so it doesn't need a database trigger.
Similar to before, edit the entity object CustomerNt by right-clicking in the navigator.
Click on the 'Attribute Settings' tab and edit the ID attribute.
- Uncheck 'Mandatory'checkbox.
- Check 'Updateable While New'.
An additional step is also required. The Create method will have to be modified to extract
the value of the sequence.
In the Edit EntityObject Wizard click the Java tab and select Create method and click Finish.
The create method is generated in your Java fil e. In the Workspace view of the Navigator,
expand the CustomerNt entity object in the navigator. Double-click
CustomerNtImpl.java to open it in the Source Editor. In the Structure pane, double-click
create(AttributeList). Modify the Create method so it looks like this:
<code>
public void create(AttributeList attributeList) {
super.create(attributeList);
SequenceImpl s = new SequenceImpl("customer_nt_seq", getDBTransaction());
Integer next = (Integer)s.getData();
setId(new Number(next.intValue())); }
</code>
Save and compile the project.
Now test the ViewObject CustomerNtView using the tester as before.
In the edit form of CustomerNTView click on the '+' to insert a record. Observe that
just as before a new value has automatically been inserted in the ID field!
TO USE A DB TRIGGER OR NOT TO USE A DB TRIGGER.
Using a Database trigger sometimes preferable if you have non BC4J applications
also sharing the database. In this case it is still safest to just let the database
update it's own primary keys.
If you don't have any other non-BC4J applications sharing the database, then not using
a database trigger is perfectly acceptable and can have slightly better performance.
The important thing to remember is that the option is yours to use either approach!
nullThank you for the reply Jonathon. I am using a ViewObject which
consist of several tables. I haven't tried the DB trigger
approach but just using the BC4 approach in overriding the
create method.
Here is the parent class create as a part of the
FasNameImpl.java file which does the job correctly.
public void create(AttributeList attributeList) {
super.create(attributeList);
SequenceImpl l_seq = new SequenceImpl
("SEQ_CUSTOMER_ID",getDBTransaction());
Integer l_next = (Integer)l_seq.getData();
setCustomerId(new Number(l_next.intValue()));
This is when I triedpassing the value to the child table. But I
can't figure it out. I think the link is working fine if I had a
ViewLink deployed but it doesn't look like it's doing the job
for ViewObject.
I am trying to call the childclass.method
(FasCustomer.setCustomerId(l_next);
But I am getting error.
Thanks a lot for your suggestions,
Kamran

Bulk Renaming Problem in Adobe Bridge
Hi
I have an inconvenient problem in bulk renaming files in Adobe Bridge CS3.
An original file name for example looks like: DSC_5521
I wish to keep the "5521" part in my bulk renaming process so it may look for example like "Landscape5521" but loose the "DSC_" bit of the original file name.
Bulk renaming appears to let me keep all the original file name or none of it. In which case I have to manually knock out the "DSC_" part of each renamed file.
Any suggestions or ideas would be gratefully received!
Many thanks
CarlCarl,
While Bridge's renaming abilities is adequate in some post-production digital workflows it fails in the industrial grade categories.
For a simple no fuss approach I have for many years now used free-ware software. If you look around on the Internet you should be able to find a renaming program that will suit your needs. Most of them are small and unobtrusive in their use and computer requirements. Myself I am quite satisfied with Smart Rename 1.0 by ZByteSoft.Com.
I regularly rename, and apply or change date stamps, for up to 4,000 files at a time. I am also able to apply system attributes to the selected files as I desire.
While such programs may not give you exactly what you wish they should come close. It may require that you slightly change your digital workflow and in that regard you may find that one little application that suits your needs to a tee.

Can I rename a PDF file based on the metadata? (prefer a bulk rename)
I had to do a file recovery on a hard drive with a program called TestDisk. It recovered 30GB+ of files but it recovered data by ignoring the partition/partition table. Because of this it uses its own naming structure during the recovery. The names of the files are f_______.XXX. I noticed that when I hover over the PDF files it actually displayed the original file name. I looked in the file proerties and noticed the PDF tab which contained this. Does anyone know if I can rename the file(s) using this data. The summary tab on the file properties is blank but the file name is located under this PDF tab (I didn't even know this existed). I don't know what I'm going to do with the rest of the files but being able to bulk rename 8GB of PDFs would be great! :-)
Thanks,
Sundiataok I'm not into programming and not familiar with Javascript. Does anyone know any websites to maybe assist me with making this batch file or at least provide enough basic Javascript info to get me started and I may be able to figure this out. Or is this Javascript something that is auto. something created during the renaming process creation?

How can I bulk sort by capture time and bulk rename files off multiple cameras?
I have found many renaming utilities, including bridge, but I have not run across any that allows bulk / batch capture time sort and rename?
I can sort by capture time in Lightroom 3, but when I export it puts the files back in original order....maybe I am doing something wrong....that would not surprise me.
I just tried sorting by Capture Time in LR3 and then exporting and renaming.... renamed but not in the capture time sort order....
so I am open to any suggestions... I shoot 2 cameras 99% of the time so I do not need to change lenses.
Thanx in advance.How can I bulk rename music files in reverse order from artist - song name to songname - artist.
I actually dont need to rename the actual files.
Its just i have a huge txt list of 100,000 music names that are listed as so.
I wonder if we haven't misunderstood what you were asking for. Could it be that you have not a huge file, but just a huge list of names in many small files. If that's the case, you should rather use the following script instead of the previous one.
Since this script does not rename the files, make a backup of your files before running it.

tell application "Finder"
set theNames to name of files of theFolder whose name extension is "txt"

Bulk rename of files in subfolders
Hello All
I have a folder containing 40 subfolders, and inside each of these subfolders are a number of files (between 4 and 45 each) totalling over 500 files.
Each filename starts with a string "orginalstring".
What I would like is the easiest way (whether using Automator or not) to replace all 500+ "orginalstring" with "replacementstring".
Many thanks for your help. PhilipAlthough the original poster's problem is long solved and it doesn't directly help.

HT204268; I have purchases on an aol login pre 2008 and all recent stuff under an apple id. I currently see and use everything when i login with the apple id. After March 31st will my apple id account still show and contain all?
I understand the instructions to create a new account id (apple id) from the old aol account. However, does this mean my purchases will be split into 2 accounts; or does the fact that I currently see everything under my apple id (regardless of the purchased by username) mean this will all still appear in my current account as it does now?You see them where when you login your non-AOL account ?
If you currently have two accounts (the AOL username account and an email address account) then you will continue to have two accounts, and nothing should change when you update the AOL account to be an email address (apart from how you access that account).
You will just be renaming the account to have an email address for accessing it, not creating a new account. -
Using Time Machine Backup Drive with NEW Macbook Pro
I just got a new Macbook Pro. I migrated from my old MacBook Pro. Now I want to use my Time Machine Disk with this new machine.
When I connect the external drive, and select back up now, it says there is not enough space (due to the fact this is a new machine and it wants to backup the entire thing)
Also, when I go into the TimeMachine, it doesn't show me anything past today. . . all of my backups are not displayed over the past year. . .
How do I make it so that the external drive displays all my old backups. . . ??
Thank you for your help.Turn off TM or set the backup drive to null. Rename your computer in Sharing preferences to the same computer name of your old computer. Turn TM back on and reselect the backup drive. TM will behave as you expect. Of course if the file dates on the new machine are all changed since the migration, then TM will correctly assume that they require backing up. You will then find that there will not be sufficient space on the drive for the new backups. If this occurs then you should simply erase the backup drive and start your TM backup anew.

HOWTO: Using a BC4J Application Module in an Stateless EJB Session Bean
HOWTO: Using a BC4J Application Module in an Stateless EJB Session Bean
by Steve Muench
Overview
BC4J provides automatic facilities for deploying any application module as a stateful EJB session bean. If you want to leverage the features of your BC4J application module from a stateless EJB session bean, it's not automatic but it is straightforward to implement. This howto article explains the details.
For our example, we will create a stateless EJB session bean that uses a container-managed transaction. To keep things simple, let's assume the session bean has a single public method on its remote interface named createDepartment() with the following signature:
public void createDepartment(int id, String name, String loc) throws AppException
AppException is an example of an application-specific exception that our method will throw if any problems arise during its execution.The goal of this article is to illustrate how to use the BC4J application module named com.example.hr.HRApp as part of the implementation of this createDepartment method on our stateless enterprise bean. Let's assume that the HRApp application module has a view object member named Departments, based on the com.example.hr.DeptView view object, based on the familiar DEPT table and related to the com.example.hr.Dept entity object so our view can be updateable.
Creating the Stateless Session Bean
We can start by using the JDeveloper Enterprise Bean wizard to create a new stateless session bean called StatelessSampleEJB implemented by:[list][*]com.example.StatelessSampleEJBBean (Bean class)[*]com.example.StatelessSampleEJBHome (Home interface)[*]com.example.StatelessSampleEJB (Remote interface)[list]
We then use the EJB Class Editor to add the createDepartment method to the remote interface of StatelessSampleEJB with the signature above. We edit the remote interface to make sure that it also reflects that the createDepartment method thows the AppException like this:
package com.example;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
public interface StatelessSampleEJB extends EJBObject {
void createDepartment(int id, String name, String loc)
throws RemoteException,AppException;
}Before we start adding BC4J into the picture for our implementation, our StatelessSampleEJBBean class looks like this:
package com.example;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
public class StatelessSampleEJBBean implements SessionBean {
public void ejbCreate(){}
public void ejbActivate(){}
public void ejbPassivate(){}
public void ejbRemove(){}
public void setSessionContext(SessionContext ctx){
public void createDepartment(int id, String name, String loc)
throws AppException {
// TODO: Implement method here
}We can double-click on the ejb-jar.xml file in our project to see the XML deployment descriptor for the bean we just created:
<ejb-jar>
<enterprise-beans>
<session>
<description>Session Bean ( Stateless )</description>
<display-name>StatelessSampleEJB</display-name>
<ejb-name>StatelessSampleEJB</ejb-name>
<home>com.example.StatelessSampleEJBHome</home>
<remote>com.example.StatelessSampleEJB</remote>
<ejb-class>com.example.StatelessSampleEJBBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
</session>
</enterprise-beans>
</ejb-jar>We need to add the extra <assembly-descriptor> section in this file to indicate that the createDepartment method will require a transaction. After this edit, the ejb-jar.xml file looks like this:
<ejb-jar>
<enterprise-beans>
<session>
<description>Session Bean ( Stateless )</description>
<display-name>StatelessSampleEJB</display-name>
<ejb-name>StatelessSampleEJB</ejb-name>
<home>com.example.StatelessSampleEJBHome</home>
<remote>com.example.StatelessSampleEJB</remote>
<ejb-class>com.example.StatelessSampleEJBBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
</session>
</enterprise-beans>
<assembly-descriptor>
<container-transaction>
<method>
<ejb-name>StatelessSampleEJB</ejb-name>
<method-name>createDepartment</method-name>
<method-params>
<method-param>int</method-param>
<method-param>java.lang.String</method-param>
<method-param>java.lang.String</method-param>
</method-params>
</method>
<trans-attribute>Required</trans-attribute>
</container-transaction>
</assembly-descriptor>
</ejb-jar>
Aggregating a BC4J Application Module
With the EJB aspects of our bean setup, we can proceed to implementing the BC4J application module aggregation.
The first thing we do is add private variables to hold the EJB SessionContext and the instance of the aggregated BC4J ApplicationModule, like this:
// Place to hold onto the aggregated appmodule instance
transient private ApplicationModule _am = null;
// Remember the SessionContext that the EJB container provides us
private SessionContext _ctx = null;and we modify the default, empty implementation of the setSessionContext() method to remember the session context like this:
public void setSessionContext(SessionContext ctx){ _ctx = ctx; }We add additional constants that hold the names of the J2EE datasource that we want BC4J to use, as well as the fully-qualified name of the BC4J application module that we'll be aggregating:
// JNDI resource name for the J2EE datasource to use
private static final String DATASOURCE = "jdbc/OracleCoreDS";
// Fully-qualified BC4J application module name to aggregate
private static final String APPMODNAME = "com.example.hr.HRApp";We expand the now-empty ejbCreate() and ejbRemove() methods to create and destory the aggregated instance of the BC4J application module that we'll use for the lifetime of the stateless session bean. When we're done, ejbCreate() it looks like this:
public void ejbCreate() throws CreateException {
try {
// Setup a hashtable of environment parameters for JNDI initial context
Hashtable env = new Hashtable();
env.put(JboContext.INITIAL_CONTEXT_FACTORY,JboContext.JBO_CONTEXT_FACTORY);
// NOTE: we want to use the BC4J app module in local mode as a simple Java class!
env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
env.put(PropertyConstants.INTERNAL_CONNECTION_PARAMS,DATASOURCE);
// Create an initial context, using this hashtable of environment params
InitialContext ic = new InitialContext(env);
// Lookup a home interface for the application module
ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(APPMODNAME);
// Using the home, create the instance of the appmodule we'll use
_am = home.create();
// Register the BC4J factory to handle EJB container-managed transactions
registerContainerManagedTransactionHandlerFactory();
catch(Exception ex) {
ex.printStackTrace();
throw new CreateException(ex.getMessage());
}and ejbRemove() looks like this:
public void ejbRemove() {
try {
// Cleanup any appmodule resources before getting shutdown
_am.remove();
catch(JboException ex) { /* Ignore */ }
}The helper method named reigsterContainerManagedTransactionHandlerFactory() looks like this:
private void registerContainerManagedTransactionHandlerFactory() {
SessionImpl session = (SessionImpl)_am.getSession();
session.setTransactionHandlerFactory(
new TransactionHandlerFactory() {
public TransactionHandler createTransactionHandler() {
return new ContainerManagedTxnHandlerImpl();
public JTATransactionHandler createJTATransactionHandler() {
return new ContainerManagedTxnHandlerImpl();
}The last detail is to use the BC4J appmodule to implement the createDepartment() method. It ends up looking like this:
public void createDepartment(int id, String name, String loc)
throws AppException {
try {
// Connect the AM to the datasource we want to use for the duration
// of this single method call.
_am.getTransaction().connectToDataSource(null,DATASOURCE,false);
// Use the "Departments" view object member of this AM
ViewObject departments = _am.findViewObject("Departments");
// Create a new row in this view object.
Row newDept = departments.createRow();
// Populate the attributes from the parameter arguments.
newDept.setAttribute("Deptno", new Number(id));
newDept.setAttribute("Dname", name);
newDept.setAttribute("Loc", loc);
// Add the new row to the view object's default rowset
departments.insertRow(newDept);
// Post all changes in the AM, but we don't commit them. The EJB
// container managed transaction handles the commit.
_am.getTransaction().postChanges();
catch(JboException ex) {
// To be good EJB Container-Managed Transaction "citizens" we have
// to mark the transaction as needing a rollback if there are problems
_ctx.setRollbackOnly();
throw new AppException("Error creating dept "+ id +"\n"+ex.getMessage());
finally {
try {
// Disconnect the AM from the datasource we're using
_am.getTransaction().disconnect();

With the EJB-Tier work done, we can build a sample client program to test this new stateless EJB Session Bean by selecting the bean in the Oracle9i JDeveloper IDE and choosing "Create Sample Java Client" from the right-mouse menu.
When the "Sample EJB Client Details" dialog appears, we take the defaults of connecting to embedded OC4J container. Clicking the (OK) button generates the following test class:
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import com.example.StatelessSampleEJB;
import com.example.StatelessSampleEJBHome;
public class SampleStatelessSampleEJBClient {
public static void main(String [] args) {
SampleStatelessSampleEJBClient sampleStatelessSampleEJBClient =
new SampleStatelessSampleEJBClient();
try {
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "welcome");
env.put(Context.PROVIDER_URL,
"ormi://localhost:23891/current-workspace-app");
Context ctx = new InitialContext(env);
StatelessSampleEJBHome statelessSampleEJBHome =
(StatelessSampleEJBHome)ctx.lookup("StatelessSampleEJB");
StatelessSampleEJB statelessSampleEJB;
// Use one of the create() methods below to create a new instance
// statelessSampleEJB = statelessSampleEJBHome.create();
// Call any of the Remote methods below to access the EJB
// statelessSampleEJB.createDepartment( int id, java.lang.String name, java.lang.String loc );
catch(Throwable ex) {
ex.printStackTrace();
}We uncomment the call to the create() method and add a few calls to the createDepartment() method so that the body of the test program now looks like this:
// Use one of the create() methods below to create a new instance
statelessSampleEJB = statelessSampleEJBHome.create();
// Call any of the Remote methods below to access the EJB
statelessSampleEJB.createDepartment( 13, "Test1","Loc1");
System.out.println("Created department 13");
statelessSampleEJB.createDepartment( 14, "Test2","Loc2");
System.out.println("Created department 14");
try {
// Try setting a department id that is too large!
statelessSampleEJB.createDepartment( 23456, "Test3","Loc3");
catch (AppException ax) {
System.err.println("AppException: "+ax.getMessage());
}Before we can successfully run our SampleStatelessSampleEJBClient we need to first run the EJB bean that the client will try to connect to. Since Oracle9i JDeveloper supports local running and debugging of the EJB-Tier without doing through a full J2EE deployment step, to accomplish this prerequisite step we just need to right-mouse on the StatelessSampleEJB node in the System Navigator and select "Run". This starts up the embedded OC4J instance and runs the EJB right out of the current out path.Finally, we can run the SampleStatelessSampleEJBClient, and see the output of the test program in the JDeveloper log window:
Created department 13
Created department 14
AppException: Error creating dept 23456
JBO-27010: Attribute set with value 23456 for Deptno in Dept has invalid precision/scale
Troubleshooting
One error that might arise while running the example is that the database connection information in your data-sources.xml for the jdbc/OracleCoreDS datasource does not correspond to the database you are trying to test against. If this happens, then double-check the file .\jdev\system\oc4j-config\data-sources.xml under the JDeveloper installation home directory to make sure that the url value provided is what you expect. For example, to work against a local Oracle database running on your current machine, listening on port 1521, with SID of ORCL, you would edit this file to have an entry like this for jdbc/OracleCoreDS :
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="OracleDS"
location="jdbc/OracleCoreDS"
xa-location="jdbc/xa/OracleXADS"
ejb-location="jdbc/OracleDS"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="scott"
password="tiger"
url="jdbc:oracle:thin:@localhost:1521:ORCL"
inactivity-timeout="30"
/>This is the data-sources.xml file that gets used by the embedded OC4J instance running in JDeveloper.
Conclusion
Hopefully this article has illustrated that it is straightforward to utilize the full power of BC4J in local mode as part of your EJB Stateless Session Beans using container-managed transaction. This example illustrated a single createDepartment method in the enterprise bean, but by replicating the application module interaction code that we've illustrated in createDepartment, any number of methods in your stateless session bean can use the aggregated application module instance created in the ejbCreate() method.

About the question I made, I tried with a single assembly-descriptor tag and a single container-transaction tag in the deployment descriptor of the session bean and these were the results.
java.lang.NullPointerException
void com.evermind.server.rmi.RMIConnection.EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER(java.lang.Throwable)

Then I tried with multiple assembly-descriptor tags each with a single container-transaction tag and the results were:

How can I make my Stateless Session bean work out? -
I am trying to do batch renaming with a counter. Unfortunately every time I try to use a counter, it stays the same number.
For example/
I have two clips that I want to rename Ceremony 1 and Ceremony 2. When I do the batch renaming, the clips change to Ceremony 1 and Ceremony 2. The counter doesn't work.
I could do keyword collections or rename them individually, but I have too many clips.
I hope someone could help me.I figured it out. As you saw above, I wasn't having a problem batch renaming the title of the clips. I was having a problem with the counter. I learned in a previous posting that when you change the name of a subclip of a clip, it changes the name of both the original clip (clip in event browser, not hard drive) and the other subclips associated with it. It doesn't matter how you rename the clip (changing the name in the Name box of the Inspector, change it by clicking the name of the clip once in the event browser and typing it in, or using custom naming (click on the gear button in Inspector to find it), the name will always change correctly. For some reason (I guess a FCPX thing lol), you can't use the counter in custom naming correctly unless you change the original name through custom renaming. If you change the original name of a clip the other two ways, then try to change the new name of the clip using custom renaming with the counter, the counter will always stay the same number.

Why does iPhoto (9.0/11) not retain the Event name when exporting more than one event? (using File -> Export -> Album name with number).
Exporting a single Event retains the Event name which is what I'd expect. But highlighting more than one event and exporting it renames the images to Events 001.JPG, Event 002.JPG etc.
I was recently on holidays and had all my events nicely split on Dad's computer but when I went to export it I couldn't retain any of this information. Now I have to replicate this all again on my computer.
It wasn't possible to export the entire library as the external drive was fat32 format an I didn't want all of it. It would be nice to export a bunch of events to someone and have it retain the name.
Does anyone have a work around or will this be fixed at some point by Apple?Why does iPhoto (9.0/11) not retain the Event name when exporting more than one event? (using File -> Export -> Album name with number).
