[equinox-dev] A problem while using OSGI together with ActiveMQ!

["Wang Zhu" <transitwang@xxxxxxxxx>]

ActiveMQConnection.DEFAULT_PASSWORD and ActiveMQConnection.DEFAULT_BROKER_URL are both defined in org/apache/activemq/ActiveMQConnection,and I have import this using "import org.apache.activemq.ActiveMQConnection ;" in my program.

If I run the codes below it works normally
public void start(BundleContext context) throws Exception {
  ServiceReference[] refs = context.getServiceReferences(
    ProducerService.class.getName (), "(ProducerPool=*)");
  String url = "">

}

 

But if change the "String url = "" above to "String pwd = ActiveMQConnection.DEFAULT_PASSWORD;"

as below it does't work

public void start(BundleContext context) throws Exception {
  ServiceReference[] refs = context.getServiceReferences(
    ProducerService.class.getName(), "(ProducerPool=*)");
String pwd = ActiveMQConnection.DEFAULT_PASSWORD ;

}

 

And the error is:Bundle 39 is not active but resolved as showed below.

osgi> ss

Framework is launched.

id State       Bundle
0 ACTIVE      system.bundle_3.2.2.R32x_v20070118

38 ACTIVE      OSGIProducer_1.0.0
39 RESOLVED    ProducerApp_1.0.0
40 ACTIVE      ProducerImplOne_1.0.0

When I tried to start bundle 39 error occurs.
