无法部署包含通过 Websphere 8.5 中的 aries 蓝图定义的骆驼路线的 osgi 包

本文介绍了无法部署包含通过 Websphere 8.5 中的 aries 蓝图定义的骆驼路线的 osgi 包的处理方法，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

我创建了一个 .eba 文件(企业包存档)，其中包含一个具有 apache 骆驼路由(Java DSL)的 osgi 包.骆驼上下文定义是通过蓝图 xml 文件完成的.当我尝试在 Websphere Application Server 8.5 中部署 .eba 文件时，出现以下异常:

I created an .eba file (enterprise bundle archive) that contains one osgi bundle having a apache camel route (Java DSL). The camel context definition is done via a blueprint xml file. When I tried to deploy the .eba file in Websphere Application Server 8.5, I got the following exception:

org.apache.aries.application.modelling.ModellerException:CWSAL0126E:建模包 ib-base_0.0.1.SNAPSHOT 时发生异常:org.apache.aries.application.modelling.ModellerException:org.osgi.service.blueprint.container.ComponentDefinitionException:不支持的节点命名空间:http://camel.apache.org/schema/blueprint.

org.apache.aries.application.modelling.ModellerException: CWSAL0126E: An exception occurred while modelling bundle ib-base_0.0.1.SNAPSHOT: org.apache.aries.application.modelling.ModellerException: org.osgi.service.blueprint.container.ComponentDefinitionException: Unsupported node namespace: http://camel.apache.org/schema/blueprint.

我的蓝图xml文件如下:

My blueprint xml file is as follows:

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:camel="http://camel.apache.org/schema/blueprint"
xsi:schemaLocation="
http://www.osgi.org/xmlns/blueprint/v1.0.0
http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-
blueprint.xsd">

<camel:camelContext id="cbrContext" trace="false">
    <camel:packageScan>
        <camel:package>a.b.c.d</camel:package>
    </camel:packageScan>
</camel:camelContext>
</blueprint>

我不太确定为什么这会在 Websphere 中失败.在 Karaf 3.0.0-SNAPSHOT 中成功部署了相同的 .eba 文件.(此版本的 Karaf 使用 Aries Blueprint 版本 1.0.0).

I am not too sure why this fails in Websphere. The same .eba file gets successfully deployed in Karaf 3.0.0-SNAPSHOT. (This version of Karaf uses Aries Blueprint version 1.0.0).

我猜在 Websphere 8.5 中使用了相同的版本或 Aries Blueprint 1.0.0 的分叉版本.

I guess the same is used or a forked version of the Aries Blueprint 1.0.0 is used in Websphere 8.5.

根据 OSGi 规范，自定义命名空间的任何蓝图扩展处理程序，如骆驼:从 OSGi 服务注册表中的键 (osgi.service.blueprint.namespace) 下检索.value 元素告诉实际的命名空间 uri .

As per the OSGi specs, any blueprint extension handlers for custom namespaces like camel: are retrieved from the OSGi Service Registry under the key (osgi.service.blueprint.namespace). The value element tells the actual namespace uri .

例如:

<service interface="org.apache.aries.blueprint.NamespaceHandler">
    <service-properties>
        <entry key="osgi.service.blueprint.namespace" value="http://camel.apache.org/schema/blueprint"/>
    <entry key="osgi.service.blueprint.namespace" value="http://camel.apache.org/schema/blueprint/cxf"/>
    </service-properties>
    <bean class="org.apache.camel.blueprint.handler.CamelNamespaceHandler">
    </bean>
</service>

我不太确定为什么 IBM 不遵守此规范.

I am not too sure why IBM does not honor this spec.

另一个值得思考的有趣点是，当我尝试使用 Websphere Application Developer Tool 创建蓝图 .xml 文件时，它仅显示 4 个扩展名，如下所示:

Another interesting point to ponder over is the fact that when I tried to create a blueprint .xml file using Websphere Application Developer Tool, it shows only 4 extensions as shown below:

IBM 蓝图扩展
JPA 蓝图支持
蓝图事务支持
蓝图资源参考支持

我确保camel-core 和camel-blueprint 包都部署在websphere 的内部存储库中.

I ensured that both the camel-core and camel-blueprint bundles are deployed in the internal repository in websphere.

我尝试将 .eba 文件部署为资产.

I tried to deploy the .eba file as an asset.

不太确定，如果我错过了什么.如果有人能指出我正确的方向，我会很高兴.

Not too sure, if I have missed something. I would be glad if someone can point me in the right direction.

最好的问候，

斯里拉曼.
