Question

我已经通过Apache Felix Maven Bundle Plugin创建了OSGi包。输出jar文件似乎很好，MANIFEST.MF如下：

Manifest-Version: 1.0
Export-Package: cz.bach.entities.ui.extensions;uses:="org.osgi.framewo
rk,cz.bach.entities.ui.extensions.output,org.slf4j,cz.bach.dataframe2

gframework.transaction.aspectj;resolution:=optional;version="3.1"

但是当我在我的项目中通过此代码加载此jar文件时..

public void installPackage(File f) throws BundleException  {
    Bundle b = ctx.installBundle("file:" + f.getPath());
    System.out.println("starting bundle: " + b + ", location: " + f.getPath());
    b.start();
}

..输出为：

starting bundle: unknown_0.0.0 [3], location: /tmp/isai-extensions.jar

这意味着bundle的符号名称是null，尽管事实上它是在MANIFEST.MF中通过行：Bundle-SymbolicName: isai-extensions指定的。此外，当我调用b.start()时，不会抛出任何异常。这是很奇怪的行为..我怎样才能正确设置符号名称？

提前致谢！

Answer 1

您可以拨打Bundle.getSymbolicName。

在您的示例代码中，您正在调用Bundle.toString。 OSGi规范没有确切地定义这个方法应该返回什么，但我有点惊讶它返回“未知”。

Answer 2

我通过删除/tmp/org.eclipse.osgi文件夹（在GNU / Linux机器上）解决了这个问题。在那一步之后，我的捆绑开始工作。

OSGi包的名称为unknown_0.0.0
