关于在java程序里调用webservice报500返回码的问题

我现在写了个程序,是调用webservice的,执行后我打印返回码是500  错误信息是

java.io.IOException: Server returned HTTP response code: 500 for URL: http://10.45.7.18:8071/ocswebservices/services/WebServices?wsdl
	at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1133)
	at com.ztesoft.zsmart.bss.sett.appstore.bll.ProtoSoapHTTPBase.write(ProtoSoapHTTPBase.java:167)
	at com.ztesoft.zsmart.bss.sett.appstore.bll.ProtoSoapHTTPBase.main(ProtoSoapHTTPBase.java:284)

我谷歌了下,所有的回答都是java服务器做了限制,需要加上

con.addRequestProperty("User-Agent", "Mozilla/4.0(compatible;MSIE5.5;Windows NT; DigExt)");

 但是我加上了还是没用  URL写http://10.45.7.18:8071/ocswebservices/services/WebServices?wsdl或者http://10.45.7.18:8071/ocswebservices/services/WebServices都不行。
错误是

InputStream input = con.getInputStream();

引起的
如果url写成http://10.45.7.18:8071/ocswebservices,会有正常的返回(普通页面,不是webservice)
这个怎么办?

附上java代码,其实可以不用看。。

关于在java程序里调用webservice报500返回码的问题
http://10.45.7.18:8071/ocswebservices/services/WebServices?wsdl可以在浏览器直接访问

通过soapUI发送报文可以查询(http://10.45.7.18:8071/ocswebservices/services/WebServices)。

说简单点就是java给webservice发送完整的xml格式的报文 然后就收返回的数据

服务器端有没有验证,如有加上验证,如下

/**

public class MyAuthenticator extends Authenticator {
    // This method is called when a password-protected URL is accessed
    protected PasswordAuthentication getPasswordAuthentication() {
 
        String username = "";
        String password = "";

        ReadProperties rnp = ReadProperties.getInstance();

		username = StrUtil.isBlank(username) ? "admin" : username;
		password = StrUtil.isBlank(password) ? "admin123" : password;

		// Return the information
        return new PasswordAuthentication(username, password.toCharArray());
    }

浏览器输入http://10.45.7.18:8071/ocswebservices/services/WebServices?wsdl是可以的
soapui发送报文也是可以的。

conn.setRequestMethod(“POST”); 改为conn.setRequestMethod(“soap”)

webservice不能发post请求吧
