如何使用OSGi容器启用ApacheTuscany SDO？[类加载器问题],osgi,classloader,apache-servicemix,sdo,apache-tuscany,Osgi,Classloader,Apache Servicemix,Sdo,Apache Tuscany,我尝试在ApacheServiceMix和SDO中使用ApacheCXF。SDO随Apache Tuscany SDO实现一起提供 以下是依赖关系图： 我的osgi包公开了一个web服务，该包依赖于SDO CXF系统包也依赖于SDO 我安装了Apache Tuscany SDO捆绑包堆栈，如下所示： osgi:install -s mvn:org.apache.tuscany.sdo/tuscany-sdo-api-r2.1/1.1.1 osgi:install -s mvn:org.apach

我尝试在ApacheServiceMix和SDO中使用ApacheCXF。SDO随Apache Tuscany SDO实现一起提供

以下是依赖关系图：

我的osgi包公开了一个web服务，该包依赖于SDO

CXF系统包也依赖于SDO

我安装了Apache Tuscany SDO捆绑包堆栈，如下所示：

osgi:install -s mvn:org.apache.tuscany.sdo/tuscany-sdo-api-r2.1/1.1.1
osgi:install -s mvn:org.apache.tuscany.sdo/tuscany-sdo-impl/1.1.1
osgi:install -s mvn:org.apache.tuscany.sdo/tuscany-sdo-lib/1.1.1
osgi:install -s mvn:org.apache.tuscany.sdo/tuscany-sdo-tools/1.1.1
起始级别为：

...

tuscany-sdo-impl                  28
tuscany-sdo-lib                   28
tuscany-sdo-tools                 28

Apache CXF Bundle Jar (2.4.6)     30

camel-cxf-transport (2.8.5)       50
...
MyApplication                     60
重新启动服务器时，会打印以下异常：

tuscany-sdo-api-r2.1中的SDOUtil类依赖于帮助器类commonj.sdo.impl.HelperProvider.java

HelperProvider.java（）的源代码

这意味着getInstance（）方法无法正常工作

如何使SDOHelper在包含的OSGi中正确初始化？
