I am bit confused with the RQM authentication.

I am able to access through HttpRequester, Rest api client but if I try the Http request with Java code, reports an error - "Javascript is either disabled or not available in your Browser".

Now I am trying the same with commandline still I get the problem with qm value.

which one is a working format, Httprequest or RQMUtility with commandline is a big question for me?

When you develop your own code, you need to be mindful with the HTTP headers. If you use other tools or browsers, they send some particular HTTP headers by default. If you keep getting the text/html format response, it is probable that you have not sent the correct HTTP header to the RQM server. Refer to the below document for details about the HTTP headers.

Hello, I have followed it as it is, below is my code

this.rqmHost = new HttpHost("internalserver.com", 443 , "https"); UsernamePasswordCredentials creds = new UsernamePasswordCredentials( "username", "password"); this.context = HttpClientContext.create();

HttpGet rootServiceDoc = new HttpGet("/qm/oslc_qm/catalog"); rootServiceDoc.addHeader("OSLC-Core-Version", "2.0"); rootServiceDoc.addHeader("Content-Type", "application/rdf+xml"); rootServiceDoc.addHeader("Accept", "application/rdf+xml");

rootServiceDoc.addHeader(BasicScheme.authenticate(creds,"UTF-8",false));

HttpClient httpclient = new DefaultHttpClient(); HttpUtils.setupLazySSLSupport(httpclient);

rootServiceResponse = httpclient.execute(this.rqmHost, rootServiceDoc, this.context);

Kindly let me know if you found something missing.

Your argument (-qm "https://internalserver.com:443/") has two issues:

 Your code looks fine from a REST perspective, but your not handling the authentication with the RQM server.  Please see the com.ibm.rqm.cleaner.internal.client.JazzHttpClient.login(Credential) method from the OSLC Cleaner Utility source. 

com.ibm.rqm.cleaner.internal.client.JazzHttpClient.login(Credential) can't be used directly as login is a protected method inside the abstract class JazzHttpClient in RQMAPIUtility.jar.

I have extended my class to use it. Please see my main functioncode below, serverUrl = new URL("https://internalserver:443/qm"); testplan_ver2 d= new testplan_ver2(serverUrl); d.login(credential);

HttpResponse rootServiceResponse = Connection.INSTANCE.executeGetService(); if (rootServiceResponse.getStatusLine().getStatusCode() != 200) { EntityUtils.consume(rootServiceResponse.getEntity()); throw new HttpResponseException(rootServiceResponse.getStatusLine().getStatusCode(), rootServiceResponse.getStatusLine().getReasonPhrase()); } }

It reports the below error: Unable to create SSL_TLS context, trying SSLv3 Exception in thread "main" java.lang.NullPointerException at com.ibm.rqm.cleaner.internal.client.JazzHttpClient.fixMethodHeader(JazzHttpClient.java:249)

could you please let me know what is missing in my code

 Chethan, you need to debug your Java code to determine the root cause of this exception.  

I debugged it,
trouble with the function:
    private void fixMethodHeader(HttpMethodBase method){     
        Map<String, String> requestHeaders = getRequestHeaders();       
        for(String name : requestHeaders.keySet()){
            method.setRequestHeader(name, requestHeaders.get(name));           
        }
    }
I think the problem is "requestHeaders" is null always. I am not able to understand why getRequestHeaders() is returning null.

methode data:
Auth state: auth requested [false]; auth attempted [false] preemptive [false]
https://internalserver.com
null,[]
org.apache.commons.httpclient.params.HttpMethodParams@2667f029
/qm/j_security_check
Auth state: auth requested [false]; auth attempted [false] preemptive [false]

have deleted few data because of the space constraint
could you help me.

You set the request headers before making a request. The server sets the response headers before sending the response back. Do you set the request headers at all anywhere in your code?

I have set the Header had missed the function: Map<String, String> getRequestHeaders();
Now I am getting ERROR com.ibm.rqm.cleaner.internal.Cleaner: login error (response code) - 401.
Actually the response code is 302 but it was changed in the if condition to 401.
