我正在尝试构建一个客户端jar文件来访问Web服务。我将jar包含在servlet / war中,使客户端进行Web服务调用。我收到以下错误:
INFO: 2011 Apr 14 14:57:32,780 MDT [http-thread-pool-8181(4)] ERROR my.package.ClientServlet - Caught exception
java.lang.ClassCastException: com.sun.xml.ws.client.sei.SEIStub cannot be cast to org.apache.cxf.frontend.ClientProxy
at org.apache.cxf.frontend.ClientProxy.getClient(ClientProxy.java:93)
at my.package.Client.<init>(Client.java:54)
at my.package.ClientServlet.testService(TestServlet.java:118)
我遇到过这篇文章http://yaytay.wordpress.com/2010/03/06/lsned-29-persuading-jdk-6-to-use-cxf-classes-rather-than-its-own-avoiding-seistub/,其中说明要解决您需要将cxf-rt-frontend-jaxws
作为依赖项进行修复的问题。所以,在我的情况下,这不是问题/解决方案。
我的客户端jar pom有这些依赖项:
<properties>
<cxf.version>2.3.3</cxf.version>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-frontend-jaxws</artifactId>
<version>${cxf.version}</version>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-ws-security</artifactId>
<version>${cxf.version}</version>
</dependency>
</dependencies>
servlet war在其lib中包含以下内容:
asm-3.3.jar
bcprov-jdk15-1.45.jar
commons-logging-1.1.1.jar
cxf-api-2.3.3.jar
cxf-common-schemas-2.3.3.jar

wss4j-1.5.11.jar
xalan-2.7.1.jar
xml-resolver-1.2.jar
XmlSchema-1.4.7.jar
xmlsec-1.4.4.jar
我还阅读了一些关于javax.xml.ws.spi.Provider
文件的帖子,但未能找到任何详细说明应该命名,包含和放置的文章。
有人能指出我正确的方向吗?

解决方案是在战争WEB-INF中包含sun-web.xml(或glassfish-web.xml)文件。见How to pick CXF over Metro on Glassfish
修改强>
glassfish-web.xml的内容:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sun-web-app PUBLIC '-//Sun Microsystems, Inc.//DTD Application Server 9.0 Servlet 2.5//EN'
'http://www.sun.com/software/appserver/dtds/sun-web-app_2_5-0.dtd'>
<glassfish-web-app>
<!-- Need this to tell Glassfish not to load the JAX-WS RI classes so it will
use the CXF ones instead -->
<class-loader delegate="false" />
</glassfish-web-app>

如果所有其他方法都失败了,您可以使用反射来覆盖服务的委托。
QName qName = new QName(wsTargetNamespace, wsName);
service = new YourServiceScheduler(loc, qName);
Field delegateField = Service.class.getDeclaredField("delegate");
delegateField.setAccessible(true);
ServiceDelegate previousDelegate = (ServiceDelegate)delegateField.get(service);
if(!previousDelegate.getClass().getName().contains("cxf")) {
ServiceDelegate serviceDelegate = ((Provider) Class.forName("org.apache.cxf.jaxws.spi.ProviderImpl").newInstance())
.createServiceDelegate(loc, qName, service.getClass());
log.info("The " + getClass().getSimpleName() + " delegate is changed from " + "[" + previousDelegate + "] to [" +
serviceDelegate +
"]");
delegateField.set(service, serviceDelegate);
}
port = service.getYourServiceSoap();

我过去尝试过CXF,遇到过像这样的奇怪例外。我假设您已经尝试CXF mailing list。
我会试着放慢速度:从CFX发行版的一个工作示例开始,一次进行一次更改,直到遇到问题为止。

从buildpath中删除JAX-WS库,这样就可以解决我的问题(ClassCastException
)SEIStub到ClientProxy。

将应用程序升级到Java 11时遇到了这个问题。最后,事实证明,我们有一些奇怪的依赖项设置和两个“冲突的”库:
cxf-rt-frontend-simple与cxf-rt-frontend-jaxws
所以我删除了所有简单的依赖项,并用jaxws替换了它们,现在一切都很好->
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-frontend-jaxws</artifactId>
<version>${cxf.version}</version>
</dependency>
为进一步阅读,我建议在Java> 8迁移中使用此线程:Replacements for deprecated JPMS modules with Java EE APIs

代替使用构造函数
Cebbcws ws = new Cebbcws();
CebbcwsPortType wsport = ws.getCebbcwsPort();
使用JaxWsProxyFactoryBean
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.getClientFactoryBean().getServiceFactory().setWsdlURL(Cebbcws.WSDL_LOCATION);
factory.setServiceName(Cebbcws.SERVICE);
factory.setEndpointName(Cebbcws.CebbcwsPort);
CebbcwsPortType wsport = factory.create(CebbcwsPortType.class);

在使用OpenJdk 11迁移到sbt 1.3.6时,也会发生此错误。
但是我当时在用:
"com.sun.xml.ws" % "jaxws-ri" % "xxx"
并用apache的jaxws替换可修复错误:
"org.apache.cxf" % "cxf-rt-frontend-jaxrs" % "3.3.0"
