Question

I have a question that can I use AS400ConnectionPool in Spring if then pls provide me the example

Answer 1

Yes, you can… I have never seen that class, but looking at the API this is pretty straithforward:

<bean id="as400ConnectionPool" class="com.ibm.as400.access.AS400ConnectionPool">
    <property name="maxConnections" value="128"/>
</bean>

Now you can simply inject the pool into your services:

@Autowired
private AS400ConnectionPool testPool;

//...

AS400 newConn = testPool.getConnection("myAS400", "myUserID", "myPassword", AS400.COMMAND);

It is even easier with Java configuration:

@Configuration
public class As400Config {

    @Bean
    public AS400ConnectionPool testPool() {
        // Create an AS400ConnectionPool.
        AS400ConnectionPool testPool = new AS400ConnectionPool();
        // Set a maximum of 128 connections to this pool.
        testPool.setMaxConnections(128);
        // Preconnect 5 connections to the AS400.COMMAND service.
        testPool.fill("myAS400", "myUserID", "myPassword", AS400.COMMAND, 5);
        return testPool;
    }

}

Note that you cannot easily call testPool.fill() in XML configuration.
