.Net高手请来看一下，利用Java向远程asp.net页面post XML字符串的错误

我用Java写了一段代码来发送一个字符串给一个ASP.net URL，当是一个简单的字符串时，可以收到回答，显示出URL的页面内容但当换成XML的字符串时，返回Server returned HTTP response code: 500 for URL:http://10.100.32.65/test/login.aspx这个url是真实存在的，当把message="this is a test"时可以成功，并读取URL的页面内容把它发给asp也面是可以成功读出来的，所以感觉这是asp.net的问题请问高人有人知道根本原因吗public static void main(String[] args) {
HttpURLConnection connection = null;   
        BufferedReader in = null;   
        try {   
            String message="<samlp:LogoutRequest xmlns:samlp=\"urn:oasis:names:tc:SAML:2.0:protocol\" ID=\"LR-1-6QcnfTsfFMDmalJphenILMNwQUTJyUYAGgs\" Version=\"2.0\" IssueInstant=\"2009-12-24T09:36:11Z\"><saml:NameID xmlns:saml=\"urn:oasis:names:tc:SAML:2.0:assertion\">@NOT_USED@</saml:NameID><samlp:SessionIndex>ST-1-9pd4anx1IpLjL50DoGNX-localhost</samlp:SessionIndex></samlp:LogoutRequest>";
            
            String url="http://10.100.32.65/test/login.aspx";
            
            final URL logoutUrl = new URL(url);
            
            final String output = "logoutRequest=" + URLEncoder.encode(message, "UTF-8");            connection = (HttpURLConnection) logoutUrl.openConnection();
            connection.setDoInput(true);
            connection.setDoOutput(true);
            connection.setRequestMethod("POST");
            connection.setReadTimeout(5000);
            connection.setConnectTimeout(5000);
            connection.setRequestProperty("Content-Length", Integer.toString(output.getBytes().length));
            connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            final DataOutputStream printout = new DataOutputStream(connection.getOutputStream());
            printout.writeBytes(output);
            printout.flush();
            printout.close();            in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            
            String str=in.readLine();
            while (str != null) {
             System.out.println("str="+str);
                str=in.readLine();
            }   
     }
        catch(Exception e)
        {
          System.out.println(e.getMessage());

    String message="<samlp:LogoutRequest xmlns:samlp=\"urn:oasis:names:tc:SAML:2.0:protocol\" ID=\"LR-1-6QcnfTsfFMDmalJphenILMNwQUTJyUYAGgs\" Version=\"2.0\" IssueInstant=\"2009-12-24T09:36:11Z\"><saml:NameID xmlns:saml=\"urn:oasis:names:tc:SAML:2.0:assertion\">@NOT_USED@</saml:NameID><samlp:SessionIndex>ST-1-9pd4anx1IpLjL50DoGNX-localhost</samlp:SessionIndex></samlp:LogoutRequest>";
