Can't access projects or issues

[Ning Lv]

I got following error when accessing a project called "TestDev",

Exception in thread "main" com.atlassian.jira.rest.client.RestClientException: No project could be found with key 'TestDev'.

My code is

public class JiraReader {

	public static void main(String[] args) throws URISyntaxException {
		final JerseyJiraRestClientFactory factory = new JerseyJiraRestClientFactory();
		final URI jiraServerUri = new URI(JIRA_URL);
		final JiraRestClient restClient = factory
				.createWithBasicHttpAuthentication(jiraServerUri,
						USER_NAME, PWD);
		final NullProgressMonitor pm = new NullProgressMonitor();
		System.out.println("Initial done");
		Project myProject = restClient.getProjectClient().getProject("TestDev", pm);
		
		final Issue issue = restClient.getIssueClient().getIssue("TES-1", pm);
		System.out.println(issue);
	}
}

error is No project could be found with key 'TestDev'. Actually I set the project name as "TestDev",
can anyone tell me how to fix it? here's my jira site

First, check that the project KEY is TESTDEV. Not the name, but the actual project key. This is prefixed on to all the issues - testdev-1, testdev-2 etc,

Secondly, does your REST user have access to at least see that project?
