Pooling web service client objects

[swaraj gupta]

Hello everyone,

I am new to Spring framework, and constantly enriching my knowledge in it.

Well I got stuck at a point, where I want to pool my web-service client object, and for the same I have made the following configurations in Spring Web Context Configuration file:

<bean id="cmrcClientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"> <property name="serviceClass" value="com.v5.ComServiceApi"/> <property name="address" value="${cmrc.service.loc}"/> <property name="username" value="${cmrc.service.un}"/> <property name="password" value="${cmrc.service.pwd}"/> <property name="features"> <util:list> <bean class="org.apache.cxf.clustering.FailoverFeature"> <property name="strategy"> <bean class="org.apache.cxf.clustering.SequentialStrategy"> <property name="alternateAddresses" ref="alternateWSAddresses"/> </bean> </property> </bean> </util:list> </property> </bean> <bean id="cmrcClient" factory-bean="cmrcClientFactory" factory-method="create" scope="prototype" /> <bean id="pooledCmrcObject" class="org.springframework.aop.framework.ProxyFactoryBean"> <property name="targetSource"> <bean class="org.springframework.aop.target.CommonsPoolTargetSource"> <property name="targetBeanName" value="cmrcClient"/> <property name="targetClass" value="com.v5.ComServiceApi"/> <property name="maxSize" value="2"/> <property name="maxWait" value="5"/> </bean> </property> </bean> <bean id="commerceClient" class="com.swaraj.client.ComClient" scope="prototype"> <property name="cmrcPort" ref="pooledCmrcObject" /> </bean> <bean name="requestController" class="com.swaraj.controller.MyController" scope="prototype"> <property name="wsClient" ref="commerceClient"/> </bean>

Here I am printing cmrcPort in class ComClient at line 12. And I am always getting the same value of cmrcPort for multiple requests that lands on MyController. I suppose, it should come as different at least in some cases.

Here is my java code for ComClient:

public class ComClient{

	CommerceServiceApi cmrcPort;

        public void createOfrs() throws WSException_Exception{
	

		synchronized (cmrcPort) {
					try {
						offers=cmrcPort.createPremiumOffers("\","\",\",null);
						 try {
								    System.out.println("cmrcPort : "+cmrcPort.toString());
									Thread.sleep(13000);
							}catch (InterruptedException e) {
								e.printStackTrace();
						}
					} catch (WSException_Exception e) {
						//e.printStackTrace();
					}	
		
		}

}

I am confused if the pool is actually getting created or not as always getting the same value printed on line 12 of class ComClient .
