Question

I have the following code:

HttpGet httpGet = new HttpGet(serverAdress + "/rootservices");
        httpGet.setHeader("Accept", "text/xml");
        HttpResponse response = client.execute(httpGet, localContext);

        String projectURL = XMLDocumentParser.parseDocument(response.getEntity().getContent(), "oslc_scm:scmServiceProviders", "rdf:resource");
        String workItemURL = XMLDocumentParser.parseDocument(response.getEntity().getContent(), "oslc_cm:cmServiceProviders", "rdf:resource");

The problem here is that I read two times the HttpResponse object. So the second time I get the exception. But although I know the problem, I can´t find an easy solution. So what is a good way to solve that problem?

Answer 1

Read the input stream returned by response.getEntity().getContent() into a byte[], stored in a local variable. See Convert InputStream to byte array in Java.

byte[] content = IOUtils.toByteArray(response.getEntity().getContent());

String projectURL = XMLDocumentParser.parseDocument(new ByteArrayInputStream(content), "oslc_scm:scmServiceProviders", "rdf:resource");
String workItemURL = XMLDocumentParser.parseDocument(new ByteArrayInputStream(content), "oslc_cm:cmServiceProviders", "rdf:resource");
