WebSphere Business Integration Adapters: An Adapter Development and WebSphere Business Integration Solution

20.6 Create the back-end application

Our back-end application is a Java application that uses RMI. To create the

back-end application:

1. Ensure that the application configuration properties are correct.

2. In the RedMaintenance folder of the SG246345 directory, open the config file

with a text editor. Example 20-1 shows the contents of the config file.

Example 20-1 The config file settings

# Configuration properties for AppStart

databaseMaxConn=5

databaseURL=jdbc:db2:SG246345

databaseUserName=db2admin

databaseUserPwd=itso4you

jdbcDriverClass=COM.ibm.db2.jdbc.app.DB2Driver

3. Modify the database password to ensure that it is correct.

4. Save and close this file.

5. Start rmiregistry.

6. Open a command window and type:

rmiregistry

Leave this window open in the background.

7. Create a shortcut on the desktop for starting the application engine, as shown

in Figure 20-20 on page 331. Ensure that the start directory is

RedMaintenance.

Note: The rmiregistry command creates and starts a remote object

registry on the specified port on the current host. If the port is omitted, the

registry is started on port 1099. The rmiregistry command produces no

output and is typically run in the background. A remote object registry is a

bootstrap naming service that is used by RMI servers on the same host to

bind remote objects to names. Clients on local and remote hosts can then

look up remote objects and make remote method invocations.

The registry is typically used to locate the first remote object on which an

application needs to invoke methods. That object in turn will provide

application-specific support for finding other objects.

8. Using this shortcut, start the application.

9. You will see in the command window the startup parameters that we use for

our application. Example 20-2 shows these parameters. Leave this window

open.

Example 20-2 Start window

C:\SG246345\RedMaintenance>start_engine

Config file is:.\Config:

10.You will also see a GUI window, shown in Figure 20-21, that is used for tracing

application activity and for problem determination.

The basic application components are now in place. We can now integrate these

components and complete the initial testing of the adapter environments.
