本文介绍了OSGI软件包无法启动的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个OSGI包，它到达了RESOLVED状态，但从来没有达到ACTIVE状态。当我运行我的应用程序时，这是我获取的堆栈跟踪： http://tny.cz/fa949f16

I have an OSGI bundle which gets to the RESOLVED state, but never reaches the ACTIVE state. When I run my application, this is the stacktrace I am obtaining: http://tny.cz/fa949f16

之后，当我尝试通过OSGI控制台显式启动捆绑包时，我收到这个错误：

Afterwards, when I try to start the bundle explicitly through the OSGI console, I get this error:

start 53
gogo: BundleException: The activator rsy.home.mac.sm.schedule.service.win.WinServiceActivator for bundle rsy.home.mac.sm.schedule.service.win is invalid

请注意，在stacktrace输出结束时，出现以下消息：

Notice that in the end of the stacktrace ouput, there's the following message:

！ENTRY org.eclipse.osgi 4 0 2014-03-14 10：52：50.984！MESSAGE Bundle
rsy.home.mac.sm .schedule.service.win_1.0.0 [53]不活动。

!ENTRY org.eclipse.osgi 4 0 2014-03-14 10:52:50.984 !MESSAGE Bundle rsy.home.mac.sm.schedule.service.win_1.0.0 [53] is not active.

这是WinServiceActivator中的代码：

Here's the code from WinServiceActivator:

package rsy.home.mac.sm.schedule.service.win;

import java.util.HashMap;

import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.osgi.framework.BundleEvent;
import org.osgi.framework.BundleListener;


public class WinServiceActivator implements BundleActivator {

    private static BundleContext context;

    @Override
    public void start(BundleContext context) throws Exception {

        ServiceActivator.context = context;

        ScheduleService schedServ = new ScheduleService();

        schedServ.setTdMapping(new HashMap<String, String>());
        schedServ.setHtMapping(new HashMap<String, String>());
        schedServ.setDoMapping(new HashMap<String, String>());

        context.registerService(ScheduleService.class.getName(), 
                schedServ, null);
    }

    @Override
    public void stop(BundleContext context) throws Exception {

        context.ungetService(context.getServiceReference(ScheduleService.class.getName()));
        ServiceActivator.context = null;
    }
}

这是我的更新文件：

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: SM Schedule Query Service
Bundle-SymbolicName: rsy.home.mac.sm.schedule.service.sm;singleton:=true
Bundle-Version: 1.0.0
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Service-Component: OSGI-INF/sm_schedule_service.xml
Require-Bundle: rsy.home.mac.sm.jaxrs.lib;bundle-version="1.0.0",
 rsy.home.mac.sm.config;bundle-version="0.1.0",
 rsy.home.mac.log,
 rsy.home.mac.sm.model;bundle-version="1.0.0",
 rsy.home.mac.sm.schedule.service;bundle-version="1.0.0",
 rsy.home.mac.sm.sm.scheduletable;bundle-version="1.0.0",
 resources;bundle-version="1.0.0",
 rsy.home.mac.portal.utilities,
 rsy.home.mac.portal.logging;bundle-version="1.0.0",
 org.eclipse.xsd;bundle-version="2.7.0",
 org.eclipse.osgi
Import-Package: org.osgi.service.http;version="1.2.1"
Bundle-ActivationPolicy: lazy
Bundle-Activator: rsy.home.mac.sm.schedule.service.sm.SmServiceActivator
Export-Package: rsy.home.mac.sm.schedule.service.sm

当googling错误Activator启动错误，ClassCastException： xxxx不能转换到org.osgi.framework.BundleActivator，我发现这个：

While googling the error "Activator start error, ClassCastException: xxxx cannot be cast to org.osgi.framework.BundleActivator", I found this:

That error is telling you that you have two copies of the BundleActivator class loaded into your VM somehow. The framework is using one and your bundle is using another.

Do you have any other bundles exporting org.osgi.framework? Where is your bundle getting this package from? If you issue the following command in the Felix shell you can see the wiring:

inspect package requirement <bundle-id>

or shortened to:

inspect p r <bundle-id>

Where <bundle-id> is the ID of your bundle, then you should see from where it is getting org.osgi.framework. If it is not the system bundle (org.apache.felix.framework), then you have an issue.

当我执行给定的命令时，我获得了这个输出：

When I executed the given command, I obtained this output:

org.osgi.framework; version="1.7.0" -> org.eclipse.osgi_3.9.0.v20130410-1557 [0]

你认为这是什么原因为什么bundle不启动？如果是这样，我该如何解决？按照我在互联网上发现的评论以及下面的人的评论和答案，我试图在MANIFEST文件中替换这一行：

Do you think this is the reason why the bundle doesn't start? If so, how can I fix this? Following this comment I found on the internet and the comments and answers from people below, I tried to replace this line in the MANIFEST file:

Import-Package: org.osgi.service.http;version="1.2.1"

通过这一个：

Import-Package: org.osgi.framework

我在代码中收到了一大堆错误，由Eclipse给出的原因是：

And I get a whole bunch of errors in the code, whose reason given by Eclipse is:

此行上的多个标记
- 访问限制：由于限制所需库
rsy.home.mac.sm.jaxrs.lib / lib / org.osgi.core-4.2.0.jar
- 访问限制：由于对所需库
rsy.home.mac.sm.jaxrs.lib / lib / org的限制，不能访问BundleListener类型.osgi.core-4.2.0.jar

Multiple markers at this line - Access restriction: The type BundleActivator is not accessible due to restriction on required library rsy.home.mac.sm.jaxrs.lib/lib/org.osgi.core-4.2.0.jar - Access restriction: The type BundleListener is not accessible due to restriction on required library rsy.home.mac.sm.jaxrs.lib/lib/org.osgi.core-4.2.0.jar

我真的很感激一些帮助，谢谢！

I would really appreciate some help on this... Thanks!
