我有一些事务代码在旧版本的Apache Karaf中运行良好.现在在Apache Karaf 4.0.4中我看到了很多例外.

java.lang.IllegalStateException:无法将事务记录为org.apache.derby.jdbc.EmbedXAResource@77cbf3e5不是NamedXAResource.

和

org.apache.aries.transaction.manager - 1.3.0 | 请更正集成并提供NamedXA java.lang.IllegalStateException:无法将事务记录为TransactionContext {transactionId = null,connection = ActiveMQConnection

我想用JPA 2.0创建OSGI持久性服务包.我使用OpenJpa作为持久性提供程序.

我尝试了一个带有JPA支持的示例OSGI包,当我的客户端调用持久性功能时,我遇到了问题.该服务无法创建EntityManagerFactory.始终为空.

我使用Apache Karaf作为安装服务的平台.

目前我正在eclipse中创建一个OSGI包,并将其作为一个包导出并在Karaf中部署.客户端可以调用该服务.但问题是当我得到EntityManagerFactory时.

我使用波纹管代码来获取EntityManagerFactory.

  OpenJPAEntityManagerFactory emf = OpenJPAPersistence.createEntityManagerFactory
    ("StudentServiceProvider","META-INF/persistence.xml");

请告诉我如何使用OpenJPA创建OSGI persitence bundle.

我需要一个命令才能获得osgi/karaf中的活动包,

I know that scr:list / osgi:list will list all the bundles irrespective of state. 

Is there any other easy way to check all the bundles are active in karaf?

问候,哈利

我正在尝试通过将eventadmin和scr功能添加到启动功能来构建自定义发行版。

我根据http://karaf.apache.org/manual/latest/developers-guide/custom-distribution.html的官方文档尝试了以下操作。

我使用以下 pom.xml 创建了一个新项目：

不幸的是，当我运行“mvn install”时，它失败了：

[ERROR] Failed to execute goal org.apache.karaf.tooling:karaf-maven-plugin:4.0.4:assembly (default-assembly) on project jf-framework-karaf: …

在我下面的示例中，OSGi 解析和 Maven 依赖项支持所需的步骤似乎存在差异/重复。

我有一个依赖于外部 3rd 方 jar 的 jar，在这种情况下是 time4j。

<dependency>
  <groupId>net.time4j</groupId>
  <artifactId>time4j-core</artifactId>
  <version>4.16</version>
</dependency>

然后我可以通过导入包和运行等在本地运行我的简单 jar。

导入 OSGi 时，我必须确保首先导入这个 jar，通常使用 PAX Wrap Url。

这对于 1 个 jar 依赖项没问题，但是当存在多个依赖项时呢。我可以使用 features.xml 文件来收集这些罐子，但为什么呢？我已经在我的 pom.xml 中指定了它们。

似乎 OSGi / Karaf 应该有一种方法可以读取 pom.xml 依赖项，并在需要时使用 PAX Wrap url 将它们导入到容器中。

我在这里错过了什么吗？

例如:

from("direct:test")
  .multicast() 
     .to("direct:req1","direct:req2");

from("direct:req1")
  .to(cxf:bean:endpoint1)
  .process("response1");

from("direct:req2")
 .process("requestProcessor2")
 .to(cxf:bean:endpoint2)
 .process(response2);

我是apache camel的新手,我只想知道有没有办法使用我从"requestProcessor2"中的endpoint1获得的响应.

我在 Karaf 4.0.5 启动期间遇到错误。我收到此错误：

(version>=1.8.0)(!(version>=2.0.0))) Unresolved requirements: [[Tracking_Service [11](R 11.0)] osgi.wiring.package; (&(osgi.wiring.package=org.osgi.framework)(version>=1.8.0)(!(version>=2.0.0)))]

您能给我一些如何解决这个问题的建议吗？

我使用这个依赖项：

<dependency>
            <groupId>org.osgi</groupId>
            <artifactId>org.osgi.core</artifactId>
            <version>6.0.0</version>
            <type>jar</type>
        </dependency> 

运行MVN安装时，我的karaf功能项目中出现错误。这是pom.xml：

当我运行mvn clean install时，出现以下错误：

大家好，我在 karaf 中使用 feature install 时遇到以下错误

我有一个简单的Camel应用程序捆绑包，该捆绑包将在Apache Service Mix 6.1下的Karaf 3.0.5中部署。配置文件放置在etc/目录中（假设它名为wf.cfg）。我想在我的应用程序包中具有动态配置更改功能。这样，无论何时更改了内容wf.cfg，都可以立即打包。为此，我在我的 blueprint.xml

<cm:property-placeholder persistent-id="wf"
    update-strategy="reload">
    <cm:default-properties>
        <cm:property name="env" value="local" />
    </cm:default-properties>
</cm:property-placeholder>

<!-- a bean that uses a blueprint property placeholder -->
<bean id="configBean" class="com.jabong.orchestratorservice.basecomponent.config.ConfigBean">
        <property name="env" value="${env}" />
</bean>

我现在面临的问题是如果将update-strategy设置为reload。然后，它似乎正在重新加载整个bean。

有人可以让我知道是否可以只重新加载configBean整个捆绑包吗？如果我能做到这一点，那么可能是我可以对configBean应用程序包可以使用的配置变量进行静态引用？

完整blueprint.xml的放在这里。
