CXF代理Web服务

web service proxy

CXF代理Web服务,web,service,proxy,cxf,Web,Service,Proxy,Cxf,我是JavaServlet过滤器的新手，我有一个CXFWeb服务a A的地址是：我想实现一个代理web服务B B的地址是：为了将请求转发到A到B，我在B中添加了一个servlet过滤器： public class RequestFilter implements Filter { public void doFilter(final ServletRequest request, final ServletResponse response, FilterChain chain)

我是JavaServlet过滤器的新手，我有一个CXFWeb服务a

A的地址是：

我想实现一个代理web服务B

B的地址是：

为了将请求转发到A到B，我在B中添加了一个servlet过滤器：

public class RequestFilter implements Filter {
public void doFilter(final ServletRequest request, final ServletResponse response, FilterChain chain)
        throws java.io.IOException, javax.servlet.ServletException {

    HttpServletResponse resp = (HttpServletResponse) response;
    String redirect="http://localhost:8080/AdditionWS/services/additioncls";
    Enumeration<String> enumeration=request.getParameterNames();
    String parameter=null;
    while(enumeration.hasMoreElements())
    {
        parameter=enumeration.nextElement();
        if(parameter.toLowerCase()=="wsdl")
        break;
    }
    // if the parameter 'wsdl' exists forward to http://localhost:8080/AdditionWS/services/additioncls?wsdl
    if(parameter!=null)
        redirect="http://localhost:8080/AdditionWS/services/additioncls?"+"wsdl";
    redirect=resp.encodeRedirectURL(redirect);
    resp.sendRedirect(redirect);
 }
}

由于某些原因，客户端请求未转发到，我收到以下错误：
