JBuilder5 WebLogic 6.1sp1 Entity Bean
This article assumes that the user has installed JBuilder5 and BAS4.5 correctly.
Install WebLogic
This example is WebLogic 6.1sp1, which is installed by default. The installation directory is set to 12345678.
Open JBuilder, select Enterprise Setup under the Tools menu, switch to the Application Server panel to select WebLogic Installation Directory to c: /bea/wlserver6.1, bea Home Directory is set to C: / BEA, then click OK. Click Default Project Properties to select the Servers panel, select the Servers panel, click on the Application Server - "....", Double-click the WebLogic Application Server 6.0 in the Application Server Selection Server 6.0 Modify VM Parameters as:
-ms64m -mx64m -djava.library.path = c: /bea/wlserver6.1/bin -dbea.home = C: / bea
-Dweblogic.domain = mydomain -dweblogic.name = MyServer
-Djava.security.policy == c: /bea/wlserver6.1/lib/weblogic.policy -classpath c: /bea/wlserver6.1/lib/weblogic_sp.jar; c: /bea/wlserver6.1/lib/ WebLogic.jar;
-Dweblogic.management.password = 12345678
Point OK, close the JBuilder. WebLogic configuration is complete.
Entity Bean
l Constructing a table in the test database
First create a table used to test, and the database name TEST Table Test We set two fields:
Name Vrachar (15) does not allow empty primary key addr varchar (50) allows empty
l Create a connection pool in WebLogic
1. Open the Start Default Server in the Start menu, and enter the password "12345678" to start WebLogic.
2. Start "Start Default Console", enter the username "system" password "12345678" to enter the console, find the "JDBC" item in the left menu, open him, you will find that there is a submenu to "Connection Pools", right Hit this item, then select "Configure a new JDBC Connection Pool ..." configuration connection pool
The property is as follows
Name MyDB URL JDBC: Sybase: TDS: 172.16.4.200: 5000 / TEST / 172.16.4.200 is the database server address, TEST is the database name /
Driver classname com.sybase.jdbc2.jdbc.sybdriver
Properties (key = value): user = sa
Aclname
Password
Click the CREAT button after completion.
3. Click the Targets tab, select MyServer, move it into the Chosen item, click Apply
4. Turn off the console and WebLogic service. The connection pool is already built.
l coding
1. Open JBuilder, create a newly named Hello project, and add WebLogic 6.0.2 in Required Libraries. Newly built an EMPTY EJB Group called HelloWorld.
3. Create a new Enterpris JavaBean, select the HelloWorld group, click Next. Package Select Hello, class name to "fistbean", Options Select Container Managed Persistence EJB 1.1 Entity Bean and click Next. Click Finish.
4. A total of 3 files under the project is

5. Click HelloWorld.ejbgrp in the left menu, then double-click First, the first-page, click the Resource References tab below, click the Add button on the panel, enter "HelloDB" point OK in the input dialog box. Select Type to java.sql.datasource. Select HelloDB and enter MYDB in the JNDI Name box below.
6. Then click on the label Persistence, TABLE (s), and the contents of the container management table are as follows.
CMP
ISPK
FIELD TYPE
Column Name (s)
Column Type
Check Name Name Varchar (15)
Select Addr ADDR VARCHAR (50)
7. Right-click on the JDBC Datasources under EJB Deployment Descriptor to create a new data source named mydb, configured as follows:
JNDI Name MyDB
URL JDBC: Sybase: TDS: OLAP: 5000 / TEST
User Name Sa
Password
Driver class name com.sybase.jdbc2.jdbc.sybdriver
Configuration Finish Click "Test Connection", if it is correct
Attempting to connect to Database ...
Connection succeed.
If you display the following information
Attempting to Connect to Database ... driver not on classpath.
Add the driver to the classpath using The set classpath command.
Then indicate that the JDBC driver of the database is not in the classpath, adds the database's driver to the project's Required Libraries.
8. Click EJB Deployment Descriptor, then click EJB DD SOURCE in the right window, then select WebLogic-Cmp-Rdbms-Jar.xml to find
9. Right-click FirstHome.java to select Properties, then select Build Panel ---> Visibroker Select the generate IIOP point OK under Java2iiop Seting
10. After saving, press CTRL F9 to compile, there should be no problem.
11. New Test EJB Client all uses the default settings.
12. Remove the main method to find fisttestclient1 client = new fistteclient1 ();
Then add the following code:
First ff = client.create ("testname", "testaddr");
Try {
System.out.println (ff.getname ());
System.out.println (ff.getaddr ());
}
Catch (java.rmi.remoteexception ex) {
EX.PrintStackTrace ();
}
Then, save compilation.
13. Right-click HelloWorld.ejbgrp, choose RUN, then select Deploy Options for "HelloWorld.jar" àDeploy
14. Open http://127.0.0.1:7001/console username password after completion, SYSTEM and 12345678 Open EJB in the left menu of the console, then select Targets to turn MyServer in the window. CHOSEN.
15. Go back to jBuilder to stop the running server, then re-right hit helloworld.ejbgrp, select RUN.
16. Right-click on the fisttestclient1.java point run, such as displaying the information below, is successful
