JBoss上的JaxWS ClassCastException [英] JaxWS ClassCastException on JBoss
问题描述
我正在使用JBoss 5.1.0.GA（用于JDK6）和jaxws 2.2.6。
当我调用webservice时，我得到以下异常：
I'm using JBoss 5.1.0.GA (for JDK6), and jaxws 2.2.6. When I invoke the webservice, I get the following exception:
java.util.ServiceConfigurationError：javax.xml.ws。 spi.Provider：

我还尝试从3.1.2.GA将jbossws更新到3.4.0版，没有任何改变。
我已经阅读了很多关于检查lib / jars of JBoss中的jar的建议，所以这是内容：
I also tried to update jbossws to version 3.4.0 from 3.1.2.GA, nothing changed. I've read a lot of suggestions related to checking jars in lib/endorsed of JBoss, so this is the content:
activation.jar
jaxb-api.jar
jaxws-api.jar
jbossws-native-factories.jar
resolver.jar
serializer.jar stax-api.jar
xalan.jar
xercesImpl.jar
我是还将switch -verbose：class添加到JVM：
I've also added the switch -verbose:class to the JVM:
[Loaded org.jboss.ws.core.jaxws.spi.ProviderImpl from jar:file:/Users/carlo/jboss-5.1.0.GA/common/lib/jbossws-native-core.jar!/]
并且该类扩展 javax.xml.ws.spi.Provider （http://bit.ly/LK9bNE）
and that class extends javax.xml.ws.spi.Provider (http://bit.ly/LK9bNE)
有人可以帮我解决这里发生的事情吗？
Can someone help me what's going on here?
编辑1
好的，所以我看到ClassCastException来自：ServiceLoader.java line 345
EDIT 1
Ok, so I see that the ClassCastException is raised from: ServiceLoader.java line 345
S p = service.cast(Class.forName(cn, true, loader).newInstance());
调用service.cast时，此是 javax.xml.ws.spi.Provider 并且要转换的arg是 org.jboss.ws.core.jaxws.spi.ProviderImpl 。
我仍然无法理解这个问题。
when service.cast is called, this is javax.xml.ws.spi.Provider and the arg to cast is org.jboss.ws.core.jaxws.spi.ProviderImpl.
I still fail to understand the problem though.
推荐答案
最后，我设法解决了我的问题：我将 jaxws-rt.jar 放入 $ JBOSS_HOME / lib / endorsed 。
Finally, I've managed to solve my problem: I put jaxws-rt.jar in $JBOSS_HOME/lib/endorsed.
编辑
我在JBoss 5.1 EAP上遇到了同样的问题，为了解决这个问题，步骤略有不同：
in $ JBOSS_HOME / lib / endorsed 我删除了旧的jaxb-api.jar，然后复制了
EDIT
I had the same problem on JBoss 5.1 EAP, and to solve it, the steps are a little different:
in $JBOSS_HOME/lib/endorsed I removed the old jaxb-api.jar, then copied
- jaxb-api.jar
- jaxb-impl.jar
- jaxws-api.jar
- jaxws- rt.jar
- jaxb-api.jar
- jaxb-impl.jar
- jaxws-api.jar
- jaxws-rt.jar
来自最新的jaxws-ri软件包，最终有效。
from the latest jaxws-ri package, and eventually it worked.
