Question

我创建了一个使用邮件Apache Camel Mail的小项目。像往常一样，他启动了这个项目并运行良好，但是一旦我尝试将其作为一个捆绑包运行，就会出现问题：

文件com.camel.mail.Activator：

public class Activator implements BundleActivator {

private CamelContext ctx = null;

public void start(BundleContext bundleContext) throws Exception {
    ctx = new OsgiDefaultCamelContext(bundleContext);
    ctx.addRoutes(new RouteBuilder() {
        public void configure() {
            Processor myProcessor = new Processor()
            {
                public void process (Exchange exchange)
                {
                    exchange.getIn().getBody(String.class);
                }
            };

            from("imaps://imap.yandex.ru?username=***&password=*****&delete=false&peek=false&unseen=true&consumer.delay=6000&closeFolder=false&disconnect=false")
                    .process(myProcessor);

        }
    });

    ctx.start();
}

public void stop(BundleContext bundleContext) throws Exception {
    ctx.stop();
}
}

如何解决此错误？谢谢！

不要运行bundle org.osgi.framework.BundleException
