How can i use the project code instead of project xml?

hello
i use the sessionbean+toplink structure,after i finish the o-r mapping by using the mapping work bench,i generate the project xml file,then in the "session.xml" file,i refer to the project xml,then i can use it from sessionbean.
i hear that if i use the project code instead of project xml file,it will be more performant,is that true?
otherwise,how can i use the project code instead of project xml file?i mean, in "session.xml", i can use the "<project-xml>" tag to refer to the project xml file,then in my session bean,i get the server session by read the "session.xml" file.but if i use the project code,how can i refer it from the "session.xml"?the examples that come with the toplink installation only tell me how can i use the project xml file within the session bean,it don't give me any clue about using the project code in the sesion bean,who can give me a step-by-step instruction and code snippet?
thank you very much?

There is a slight performance gain during session load at startup but there is no difference at runtime. The choice of which to use is dependent upon you build process. Whether it is easier to submit a new version of the class into the comile build process vs an XML file. In most cases it is just a preference of the development team.
When you use the project-class you'll need to generate the source code and compile it into your system. Typically it is packaged with the persistent classes. You may need to configure your environment so that the class-loaders have access to these classes (same for the XML case).
When using the project-class you simply replace the project-xml entry like this:
<project-class>oracle.toplink.demos.employee.relational.EmployeeProject</project-class>
The DTD for the session.xml file is found at <TOPLINK_HOME>\core\sessions_4_5.dtd. It is also in the documentation at:

Contacts are designed to be synced to a supported application on the computer or a cloud service.
Pictures taken with the device are designed to regularly be copied off the device to a computer as would be done with any digital camera.
If you have failed to use the device as designed it may be too late to recovery anything.
Is the device regularly backed up to a computer via iTunes? If so, the most recent backup (when restored to a replacement iOS device) should contain all contacts and pictures as of when the backup was created.

How can I use the setup utility with my gaming adapter?

How can I use this program (the cd that came with my netgear wireless game adapter) to setup my gaming adapter? I want to configure my gaming adapter but it seems like i cannot do so? How can I achieve this?

Hi again,
thought a bit about this...
This thing looks to me like a special sort of wireless router with one ethernet port, which also is a bit old I guess.
With nowadays wireless router, the configuration usually is made using a Web-Browser like Safari or Firefox and accessing the router through a built-in webpage.
The IP adress of the router is also usually 192.168.0.1.
Have a look inside the Netgear-Documentation, to see if this also possible here.

How Can I unlock the restriction code on my ipad

Hello I am trying to unlock the restriction code on my ipad but can't cuz I forgot the passcode

You can't unlock the restriction code.
You have to restore your iPad as a new device and not from a backup.The backup will only load the forgotten passcode onto the device again. You will have to load all of your content onto the device so make sure that you have all content in iTunes as well - transfer purchases to iTunes on your computer.

How can I use the green screen with iMovie?

Hey guys! I was wondering how does the green screen effect work with iMovie 11? I need to use green screen in iMovie in school for a project and I am trying to troubleshoot the problem.
Help is appreciated.
Thanks,
Ben

Record a video against a green screen and import it to imovie.
Then place the green screen footage ON TOP of the background you want and a list should come up. Select green screen. Also, before you do any of that make sure that your advanced tools are selected under preferences in imovie.

How can I use the Connection Pool with DB2

Hi All,
I am facing the problem with the usage for the Connection Pool.
I want to use DB2 via JNDI lookup.
But when starting the Weblogic server, Error occured with the following message.
<Error> <JDBC> <Cannot startup connection pool "MyJDBCPool" Cannot load driver class : com.ibm.db2.jdbc.app.DB2Driver>
DB2 and Weblogic are on the same machine.
In case of the use of remote DB2 database, I also encountered the same error.
Configurations are as follows.
<JDBCConnectionPool DriverName="com.ibm.db2.jdbc.app.DB2Driver"
MaxCapacity="10" Name="MyJDBCPool"
Password="{3DES}gCGsOfD9M6iwOtgL2v/NpA==" Targets="myserver"
TestConnectionsOnReserve="false" TestTableName="test" URL="jdbc:db2://localhost:6789/yongjoo"/>
<SNMPAgent Name="mydomain"/>
<JDBCDataSource JNDIName="acsdb" Name="acsdb" PoolName="MyJDBCPool" Targets="myserver"/>
Could you please give some information about this problem? I will appreciate your kindness.

Hi Joe,
Thanks your help.
Perhaps It's my fault for Weblogic console's setting.
After I reset the target server in console, Error message disappeared.
But, when I call the TestCode, I encountered another error message. The error
is NameNotFoundException.
When lookingup the JNDI name, NameNotFoundException errer occured. I tried to
change my setting and JNDI name, but the results are the same.
Would you please give me some information about this one more time? I will be
appreciated for your help.
Follows are Config.xml
<JDBCConnectionPool DriverName="com.ibm.db2.jdbc.app.DB2Driver" MaxCapacity="10"
Name="MyJDBCPool" Password="{3DES}gCGsOfD9M6iwOtgL2v/NpA==" Targets="myserver"
TestConnectionsOnReserve="false" TestTableName="test"
URL="jdbc:db2://localhost:6789/yongjoo"/> <SNMPAgent Name="mydomain"/>
<JDBCDataSource JNDIName="acsdb" Name="acsdb" PoolName="MyJDBCPool"
Targets="myserver"/>
and follows are TestCode,
url = "t3://localhost:7001"; //default URL
datasource = "jdbc/acsdb";
Context ctx = null;
Hashtable p = new Hashtable();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
p.put(Context.PROVIDER_URL, url);
try{
ctx = new InitialContext(p);
System.err.println("initialContext(p)"+ctx); <-- success
ds = (DataSource)ctx.lookup("java:comp/env/jdbc/acsdb");
}catch(NameNotFoundException ne){
throw new ConnectionException(); .
}catch(NamingException ne){
throw new ConnectionException();

How can I use the tabbed panel with the accordion panel options of close all panels and over/not overlap the items below?

Ideas for features in Adobe Muse

I assume this is what you want to achieve in the footer....
Make sure in Muse before you export that the panel is closed, and also as Brad suggested, make sure Overlap Items Below is unchecked. I would also check the "Can Close All" button.

Since I am writing the book in Italian,how can I replace the word CHAPTER with CAPITOLO ?

Since I am writing the book in Italian, how can I replace the word CHAPTER with CAPITOLO ?

I think you need to run iBA in Italian so the templates are in that language. You can do that by switching your OS X to Italian and then reopening iBA or perhaps by using this app to just change the iBA language:
