Preparation
Suppose you have installed J2EE 1.4 SDK in your computer, you must go before the Duke Bank application is created.
http://java.sun.com/j2ee/1.4/download.html #tutorial Download J2ETORIAL Complicated Pack and Unpacking it, assumes that the path you decompress is
l Set the value of J2EE.HOME to your application server (Application Server) installation location, for example your application server is installed in C: / Sun / Appserver, then you should set the following: J2EE.HOME = C: / sun / Appserver
l Set the value of J2EE.TUTORIAL.HOME to your J2EETORIAL installation location, for example: J2EE.TUTORIAL.HOME = C: / J2Eetutorial14
l If you install the application server, the administrator's username is not using the default admin, then you have to change the value of admin.uses to your username.
l If you install an application server, you don't use the default 8080 port, you have to change the value of Domain.Resources.port to your port.
l Sets the value of the "the value of as_admin_password in the
2. Start the server
You must first start the PointBase database server and add information about the customer and account to the database, you have to add some resources to the application server, and finally you can start packaging, deploying, and operating examples.
2.1 Creating a Bank Database
You must first create a database and enter data to the data table, then enterprise beans to read or write data from it, follow these steps to create a data table and enter the data:
1. Start the PointBase database server
2. Open the command line, go to
2.2 Capture Database Mode
After creating a table and entering the data, you can capture the structure of the table and save it into a mode file, capture the mode by following the steps:
1. Open the command line and switch to
2.3 Creating a JDBC Data Source
Duke Bank's enterprise bean uses JNDi Name JDBC / BankDB to reference the database, follow these steps:
1. Open the management terminal page
Http: // localhost: 4848 / asadmin
2. Expand the JDBC branch, select JDBC Resources, select New
3. Name it as jdbc / bandb and map it to PointBasePool
2.4 Add users and groups to the File domain
After adding users and groups to the FILE security domain, the application server can determine which users can access the web client's enterprise bean methods and resources, the steps added are as follows:
1. Open the management terminal page
Http: // localhost: 4848 / asadmin
2. Expand the Configuration branch and expand the Security branch
3. Expand the Realms branch and select the File domain
4. Click Manage Users and click New
5. Enter the user and group of Duke Bank according to the following table
User
Password
Group
200
J2EE
BankcuStomer
Bankadmin
J2EE
Bankadmin
3. Compile DUKE Bank Application Code
Open the command line, go to the
4. Package and deploy DUKE Bank Application
The following process assumes that you are more familiar with the process of packaged enterprise beans, application client, and web applications with deployment tools. Here is how to pack and deploy Duke Bank (if you do this, deploy or run this application) There is also a problem, then you can use our EAR files that are available in the

In the directory, the content is as follows:
Package com.sun.ebank.Web;
Import javax.servlet. *;
Import javax.servlet.http. *;
Import com.sun.ebank.util.debug;
Import com.sun.ebank.web. *;
Import java.io.ioException;
/ **
* this is a dumb Hack. Update 4 Seems to Broken Unless A * Customerbean Is Placesd in The Request Linked to The BeanManager.
* Naturally, we need to add a beanmanager to the session here,
* Doing some of the work the dispatcher sheap.
* /
Public Class Customerhackfilter Implements Filter
{
Private filterconfig filterfig = null;
Public void init (FilterConfig filterConfig)
Throws servletexception
{
THIS.FILTERCONFIG = FilterConfig;
}

IF (beanManager == null) {
Debug.print ("Hack - Creating Bean Manager.");
Beanmanager = new beanmanager ();
Session.setttribute ("BeanManager", BeanManager;
}
Customerbean Customerbean = New Customerbean ();
CustomerBean.setBeanMAGER (BeanManager);
Request.setttribute ("Customerbean", Customerbean;
Debug.print ("Hack - Added Customerbean to Request");
Chain.dofilter (Request, Response);
}
}
2. Re-build source code
3. Select the dukesbankwar module, edit the content, find COM / Sun / EBANK / Web / CustomerhackFilter.class, add it to the package.
4. Select the DukesBankwar module, click Edit Filter List, click Add Filter in the pop-up dialog box, select com.sun.ebank.Web.customerhackfilter, filter name for Customerhack in Filter Class drop-down list, select OK
5. Still in this label, click Add, pop up "Add servlet filter mapping", select CustomerHack in the Filter Name drop-down list, select "Filter this servlet", select OK, as shown below.
6. Save this module and re-deploy it to fix an error
