Spring+Quartz+commonj+WorkManagerTaskExecutor+Webs phere

[prem11]

Hi,
I am using Spring+Quartz+commonj+WorkManagerTaskExecutor on Websphere to do some job scheduling.
Problem: I would like to call a Jersey Resource by using Jersey Client API or HTTPClient inside the scheduler method at certain time intervals. My job bean gets triggered and a simple system.out works expected. But if i implement my logic (by using Jersey client) within that execute method, then that logic was never called or nothing happens.

Web.xml

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
           classpath:scheduler-config.xml
        </param-value>
    </context-param>

scheduler-config.xml

<bean id="sampleJob" class="de.scheduler.ScheduleTimer" lazy-init="default" autowire="default" dependency-check="default" />

ScheduleTimer.java

public class ScheduleTimer {
    public void executeJob() {
        System.out.println("Job started at: " + new Date());
ClientConfig config = new DefaultClientConfig();
Client client = Client.create(config);
WebResource service = client.resource("http://localhost:10040/AppContext");

// Get plain text
		System.out.println(service.path("webresources").path("addsmsmessage").queryParams(params).accept(			MediaType.TEXT_PLAIN).post(String.class));

Please help me.
