带有Equinox OSGi的JAX-WS

我们使用JAX-WS和ProSystem OSGi创建了一个Web服务。 在一个独立的Java应用程序中,使用以下代码访问服务是很好的 以及在ProSystem框架中。

this.service = new MyServicePortService(
            new URL("http://" + host + ":" + port + "/MyService?wsdl"),
            new QName("http://myservice.example.com/", "MyServicePortService"));
this.client = this.service.getMyServicePort();

因为JAX-WS需要一些来自 javax.* 还有一些我必须通过框架包导出它们。这可以通过告诉ProSystem框架通过其配置导出它们来完成,但也可以通过使用以下导出语句编写扩展包来完成:(我们为Equinox所做的工作)。

Export-Package
  com.sun.net.ssl.internal.ssl          
  com.sun.xml                           
  com.sun.xml.internal.bind.api         
  javax.crypto                          
  javax.crypto.spec                     
  javax.jw                              
  javax.naming                          
  javax.naming.directory                
  javax.naming.event                    
  javax.naming.ldap                     
  javax.naming.spi                      
  javax.net                             
  javax.net.ssl                         
  javax.security.cert                   
  javax.transaction.xa                  
  javax.xml.bind.util                   
  javax.xml.stream                      
  javax.xml.transform.stax              
  javax.xml.ws                          
  org.apache.log4j                      
  sun.security.action

我的理解是,这也应该在Equinox中工作,因为它们使用相同的JVM。因此,如果这些包是可访问的,那么JAX-WS应该在这两个包中都工作。

但是,打电话 this.service.getMyServicePort() 将导致以下异常:

有人知道怎么解决这个问题吗?或者是否有其他/更好的可能性从Equinox访问服务?(不使用dosgi,因为其他本地应用程序也应该可以访问该服务)。

谢谢你的好意
