distributed osgi java first web service

Anonymous — Sat, 16 Nov 2024 12:12:42 GMT

Hello!
We have web service, wich was created using developer guide java first sample.
We need it to be able to handle requests like usual web service. So we implemented distributed osgi lib.
It works fine with talend esb 4.2.1 and later version 5.0.2.
After migrating to version 5.1.1 web service fail to run.
This is console output:

I thought version of cxf-dosgi i was using was too old(ver 1.1)
I tried every available version, and got errors like:

Hello!
In previous versions of talend my actions were:
- put cxf-dosgi-ri-singlebundle-distribution-1.1 into deploy folder
- put org.osgi.compendium-1.2.0 into deploy folder
- in my Activator:
public class Activator implements BundleActivator{
private ServiceRegistration registration;
public void start(BundleContext context) throws Exception {
try {
ServiceImpl implementor = new ServiceImpl();
Dictionary<String, String> props = new Hashtable<String, String>();
props.put("osgi.remote.interfaces", "*");
props.put("osgi.remote.configuration.type", "pojo");
props.put("osgi.remote.configuration.pojo.address", "http://localhost:9000/ws_customer_portal");
registration = context.registerService(ServiceImpl.class.getName(), implementor, props);
} catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
throw e; }

Hi, perhaps this sample (tested back in May on Talend ESB) is something you can leverage: http://www.jroller.com/gmazza/entry/java_first_web_service

Thanks.
It works for me.
One question. Is it possible to change endpoint address or port? As tutorial tells default URL used by Talend ESB is http://localhost:8040/services/doubleit, how can i change it ot http://localhost:9000/doubleit ?

Edit the etc/org.ops4j.pax.web.cfg
org.osgi.service.http.port = 8040
