Java Web服务错误:com.ctc.wstx.exc.WstxEOFException:prolog中出现意外的EOF

Question

我在创建Java客户端并将其连接到正在运行的Web Service时遇到问题.

我使用以下代码:

Service myService  = null;
URL wsdlLocation = new URL("http://myservice?wsdl");
QName serviceName = new QName(wsdlLocation, "MyService");
Service myService = new Service(wsdlLocation, serviceName);

使用以下命令创建Service类的位置:

wsimport -d gen -keep http://myservice?wsdl

我也尝试过使用Apache cxf 2.4的wsdl2java生成的客户端,但得到了相同的结果.

(我已经在我使用原始代码的代码中更改了此帖子的WSDL位置和服务类名称.)

但是当我使用新的Service()命令创建服务时,我在appserver上调用Web Service时遇到异常.但是:我用SOAP UI测试了wsdl位置,它运行得很好.此外,我使用Soap UI创建了一个模拟服务,我的Java客户端可以连接到它,调用它并获得结果.当我想要调用在appserver上运行的Web服务时,会出现问题.

有人可以帮帮我吗？

我遇到此错误，发现它似乎是由于使用了返回HTTP 302重定向而不是直接返回WSDL的URL所致。

我使用的URL格式为/Service?wsdl，该重定向到该格式的URL /Service/wsdl/Service.wsdl。一旦我直接使用重定向目标URL，一切都将正常工作。
