使用Apache Felix,我有一个我编写的OSGi组件,它包含了我公司使用的一些中间件.目前它依赖于大量的外部库,我似乎已经遇到Bundle-classpath:参数长度的限制.我不得不将诸如commons-collections.jar之类的库重命名为ccoll.jar.

我很好奇是否有人有任何关于解决这个限制的建议？

Bundle-ClassPath: .,lib/log4j.jar,lib/cvfs.jar,lib/backport.jar,lib/cbeanutils.jar,lib/ccodec.jar,lib/ccoll.jar,lib/chttp.jar,lib/cjxpath.jar,lib/clang.jar,[libs redacted],lib/saaj-api.jar,lib/saaj-impl.jar,lib/Schemas.jar,lib/xbean.jar,lib/clog.jar,lib/dom4j.jar,lib/xml-apis.jar,lib/xerces.jar,lib/xalan.jar,lib/jaxp-ri.jar,lib/japi.jar,lib/mail.jar

我想我可以通过不使用lib/bits来获得更多字符,但我很好奇这是一个错误,一个明确的限制,还是仅仅是我自己的愚蠢.

我有以下组件：

@Component(
    label = "Service name",
    description = "Service description",
    metatype = true,
    immediate = false)
@Properties({
    @Property(
            label = "My Label"
            name = "property-name",
            value = "my value",
            propertyPrivate = true
    )
})
@Service
public class SampleServiceImpl implements SampleService {
    private final Logger log = 
        LoggerFactory.getLogger(this.getClass());

    /**
     * OSGi Properties *
     */
    private static final String DEFAULT_SAMPLE = "hello!";
    private String mySample = DEFAULT_SAMPLE;
    @Property(label = "Prop name", 
              description = "Prop description", 
              value = DEFAULT_SAMPLE)
    public static final String …

我正在尝试将 Apache POI 导入到 Atlassian Jira 插件以读取 excel 文件。

一开始，我开始只添加

<dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
        <version>${poi.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml-schemas</artifactId>
        <version>${poi.version}</version>
    </dependency>

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>${poi.version}</version>
    </dependency>

poi.version 是 3.14

然后当我启动插件时它给出了

Unresolved constraint in bundle com.tezExtensions [165]: Unable to resolve 165.0: missing requirement [165.0] osgi.wiring.package; (osgi.wiring.package=com.sun.javadoc)

然后我用一些指令编辑了 pom，这些指令是我在另一个 StackOverflow 问题Pax Exam issue with Apache POI wrapped bundle 中发现的

我是Apache karaf和OSGI的新手。我试图编写并运行一个非常简单的捆绑软件。但是启动该捆绑包时出现此错误：

我目前正在尝试使用iPOJO为Felix实现自定义shell命令.我的示例实现如下:

import java.io.PrintStream;

import org.apache.felix.ipojo.annotations.Component;
import org.apache.felix.ipojo.annotations.Provides;
import org.apache.felix.shell.Command;

@Component(immediate = true)
@Provides
public class SampleCommand implements Command {


    @Override
    public String getName() {
        return "testcmd";
    }

    @Override
    public String getUsage() {
        return "testcmd";
    }

    @Override
    public String getShortDescription() {
        return "test command";
    }

    @Override
    public void execute(String line, PrintStream out, PrintStream err) {
        out.println("execute testcmd!");
    }

}

当我在Felix上部署Bundle时,我的SampleCommand被实例化并且getName()被调用.但是当我尝试在shell上执行"testcmd"时,我得到:

gogo: CommandNotFoundException: Command not found: testcmd

还有什么需要考虑的问题吗？

我正在尝试使用maven-bundle-plugin创建一个包.该项目的pom.xml是:

    I suggest you use the most current versions of the plugin's. 
    Search the Central Repository for the most current versions http://search.maven.org/

    Use the search strings below and update the appropriate versions

    // Felix

    g:"org.apache.felix" a:"maven-bundle-plugin"

将服务注册为普通服务与将其作为ServiceFactory之间的区别是什么？

例如 :

我有一个正常的osgi组件,我正在使用服务scr注释进行服务

@Component 
@Service 
class Service1 implements Service1Interface { 
...
... 
... 
}

现在,我有另一个osgi组件,我将作为服务注册ServiceFactory标志为true

@Component 
@Service(serviceFactory=true )
class Service1 implements Service1Interface { 
...
... 
... 
}

这两者究竟有什么区别？它们在容器中注册时是否存在差异？在什么情况下我们应该选择ServiceFactory？

我正在尝试使用Configuration Admin将配置信息传递给捆绑包.我正在使用基于Equinox OSGI实现的声明式服务.首先,因为我找不到Config Admin的Equinox实现我已经安装了felix实现,所以如果有人建议我可以获得equinox版本,那将会很棒.

我的主要问题是:当我运行程序时,我一直收到以下错误.看起来像一个null'配置'对象被传递给我的更新方法.

我创建了一个configurator包来创建配置对象,其中的主要内容是activate方法(由声明性服务调用)是:

当在调度程序上请求页面时，我在发布实例error.log中看到了这一点

因此etc.clientlibs不会加载到调度程序中，而是发回 404。

过滤规则似乎默认允许 clientlibs/0002 { /type "allow" /url "/etc.clientlibs/*" }

我在网上做了一些挖掘，发现了以下潜在的解决方法：

\n
1. 允许匿名 读取访问/etc。
\n
2. 明确拒绝 的第一级子级的 匿名 读取访问，/etc以确保您不\xe2\x80\x99t 允许事物通过。
\n

虽然这似乎暂时解决了问题，但我认为这充其量只是一种解决方法。

有谁知道这个问题的解决方案以及如何在不更改 OOTB 权限的情况下解决此问题？

谢谢，
