【发布时间】：2013-12-28 01:40:24
【问题描述】：

符号名 ram

线程“主”org.osgi.framework.BundleException 中的异常：捆绑 ram [1] 中未解决的约束：无法解析 1.0：缺少要求 [1.0] osgi.wiring.package； (osgi.wiring.package=android.dalvik) 在 org.apache.felix.framework.Felix.resolveBundleRevision(Felix.java:3826) 在 org.apache.felix.framework.Felix.startBundle(Felix.java:1868) 在 org.apache.felix.framework.BundleImpl.start(BundleImpl.java:944) 在 org.apache.felix.framework.BundleImpl.start(BundleImpl.java:931) 在 test9.Shulkam_Demo.main(Shulkam_Demo.java:35)

我的代码是..

import java.util.HashMap;
import java.util.Map;
import java.util.ServiceLoader;

import org.osgi.framework.Bundle;
import org.osgi.framework.BundleContext;
import org.osgi.framework.launch.Framework;
import org.osgi.framework.launch.FrameworkFactory;

public class Shulkam_Demo {

public static void main(String[] args) throws Exception{
    // TODO Auto-generated method stub

    FrameworkFactory frameworkFactory =    ServiceLoader.load(FrameworkFactory.class).iterator().next();
    Map<String, String> config = new HashMap<String, String>();
    //TODO: add some config properties
    Framework framework = frameworkFactory.newFramework(config);
    framework.start();
    //System.out.println(framework.getSymbolicName());

    //framework.start();

   //System.out.println( "bundle id" +framework.getBundleId());
    BundleContext bc = framework.getBundleContext();

    Bundle b = bc.installBundle("file:C:\\Documents and Settings\\Rishika Inc   Lab\\Desktop\\delete12\\shulkam_accounts-0.0.1-SNAPSHOT.jar");

    System.out.println("symbolic name "+b.getSymbolicName());
    b.start();
    System.out.println("frame work started");

    framework.waitForStop(0);

    System.out.println("shut dow");

}

而 build.xml 是

任何帮助......

【问题讨论】：

标签： java eclipse osgi-bundle

【解决方案1】：

我觉得

<Export-Package>*</Export-Package>

是原因。使用

<Export-Package></Export-Package>

除非你真的导出了一些东西。

【讨论】：

【解决方案2】：

你有一个缺少依赖的问题：

missing requirement [1.0] osgi.wiring.package (osgi.wiring.package=android.dalvik)

并且您已指定不想将其放入导入包中：

<Import-package>
com.mysql.jdbc;version="5.1.15",
org.osgi.framework;version="1.3.0",
!osgi.wiring.package,
!android.dalvik

要获得它，您应该将它放在您的 Import-Package 中。
